Getting Started with MAPI

Getting Started with MAPI

(update 3/22/2007 1:59pm: see comments for .NetCF equivalent)

 

I’m Jay Ongg, and I’m a developer for Mobile Devices at Microsoft. I’ve been in this division for a little over four years, and as part of my job, I work with OEMs and ISVs. I’m here to write some articles on how to do some useful Messaging tasks.

 

Messaging is one of the areas that developers have trouble with, partly due to lack of documentation or examples. In order to deal with Messaging stores on a Windows Mobile device, developers have to work with MAPI. Unfortunately, until you get used to it, MAPI isn’t an easy beast to tame.

What Messaging Accounts do I have?

 

One of the common questions that we have is, “how do I enumerate all the accounts on a device?” Often, the developer is looking for a particular account by name or with a particular property. I’ll enumerate the steps needed to print out the name of every account on the device.

 

These are the steps needed:

1. Login to MAPI
2. Obtain the table of message stores
3. Iterate through every row in the table
   1. MessageBox each display name
4. Log out of MAPI

 

OK, how do I do it?

Here is the function. I’ll break it down below …

#include <atlbase.h>

#include <cemapi.h>

#include <mapiutil.h>

#include <mapidefs.h>

#define CHR(x) if (FAILED(x)) { hr = x; goto Error; }

HRESULT DisplayMessageStores()

{

    HRESULT hr;

    CComPtr<IMAPITable> ptbl;

    CComPtr<IMAPISession> pSession;

    SRowSet *prowset = NULL;

    SPropValue *pval = NULL;

    SizedSPropTagArray (1, spta) = { 1, PR_DISPLAY_NAME };

   

    // Log onto MAPI

    hr = MAPILogonEx(0, NULL, NULL, 0, static_cast<LPMAPISESSION *>(&pSession));

    CHR(hr); // CHR will goto Error if FAILED(hr)

   

    // Get the table of accounts

    hr = pSession->GetMsgStoresTable(0, &ptbl);

    CHR(hr);

   

    // set the columns of the table we will query

    hr = ptbl->SetColumns ((SPropTagArray *) &spta, 0);

    CHR(hr);

   

    while (TRUE)

    {

        // Free the previous row

        FreeProws (prowset);

        prowset = NULL;

        hr = ptbl->QueryRows (1, 0, &prowset);

        if ((hr != S_OK) || (prowset == NULL) || (prowset->cRows == 0))

        {

            break;

        }

        ASSERT (prowset->aRow[0].cValues == spta.cValues);

        pval = prowset->aRow[0].lpProps;

        ASSERT (pval[0].ulPropTag == PR_DISPLAY_NAME);

        MessageBox(NULL, pval[0].Value.lpszW, TEXT("Message Store"), MB_OK);

    }

    pSession->Logoff(0, 0, 0);

Error:

    FreeProws (prowset);

    return hr;

}

The Breakdown

In this code snippet (as well as future ones), I’ll tend to use ATL smart pointers and the CHR macro a lot. The CHR macro essentially checks the input parameter for an HRESULT failure, and if it fails, goto Error. For the purposes of sample code, I’ll be using it rather than doing manual error checking.

Login to MAPI

    hr = MAPILogonEx(0, NULL, NULL, 0, static_cast<LPMAPISESSION *>(&pSession));

    CHR(hr); // CHR will goto Error if FAILED(hr)

Pretty straightforward. Log into MAPI and get a pointer to an IMAPISession

Obtain the table of message stores

    // Get the table of accounts

    hr = pSession->GetMsgStoresTable(0, &ptbl);

  CHR(hr);

Again, pretty straightforward.

 

Iterate through every row in the table

First we initialized a struct at the beginning of the function. This struct is used to set the columns of the output from the upcoming message stores table query.

 

    SizedSPropTagArray (1, spta) = { 1, PR_DISPLAY_NAME };

       …

    // set the columns of the table we will query

    hr = ptbl->SetColumns ((SPropTagArray *) &spta, 0);

    CHR(hr);

   

SizedSPropTagArray is a helper macro defined in mapidefs.h that creates a sized array. We assign it one element, with the value PR_DISPLAY_NAME, which is defined in mapitags.h. I’ll talk more about this later.

 

After we create the struct, we call IMAPITable::SetColumns to set the columns.

 

The actual iteration:

    while (TRUE)

    {

        // Free the previous row

        FreeProws (prowset);

        prowset = NULL;

        hr = ptbl->QueryRows (1, 0, &prowset);

        if ((hr != S_OK) || (prowset == NULL) || (prowset->cRows == 0))

        {

            break;

        }

       …

    }

This code iterates through every row in the message stores table. We query one row at a time. FYI, IMAPITable::QueryRows will only return a max of 10 rows. IMAPITable::QueryRows will also automatically increment the internal row counter, so subsequent invocations will get the next row.

 

MessageBox each display name

        ASSERT (prowset->aRow[0].cValues == spta.cValues);

        pval = prowset->aRow[0].lpProps;

        ASSERT (pval[0].ulPropTag == PR_DISPLAY_NAME);

After querying the row, we do some ASSERTs to check that we got the expected number of columns as well as the correct property. PR_DISPLAY_NAME is the property that the account name is in, and is of type TCHAR *. You can infer this from the definition in mapitags.h:

#define PR_DISPLAY_NAME PROP_TAG( PT_TSTRING, 0x3001)

 

The SPropValue struct contains a member, Value, which is a union of a bunch of different types. So we have to access the wide-string member of the union, and print it out:

        MessageBox(NULL, pval[0].Value.lpszW, TEXT("Message Store"), MB_OK);

 

The memory pointed to by lpszW is allocated by MAPI, and we need to free the rowset (when we re-enter the loop, as well as when we exit the function):

        // Free the previous row

        FreeProws (prowset);

Log out of MAPI

   pSession->Logoff(0, 0, 0);

The most complex part of the function :)

 

Building

Make sure that when you build your project, you link in cemapi.lib as well.

So what else can I do?

So far I’ve given you a function that prints out the message store names, but there are many properties that you can query for. A quick glance of mapitags.h will give you some tips. Don’t go writing at tags if you don’t know what they do though!

 

In future articles I’ll talk about more advanced topics, such as getting the message store pointer, and iterating through folders/messages.

 

Hope this article helps some of you out. Feel free to leave a comment if you have any questions or ideas for blog topics!

  OK, here's how you do it in C#: make sure you have added Microsoft.WindowsMobile.PocketOutlook to your project (you get this from the Windows Mobile 5 SDK). This is the equivalent function: using Microsoft.WindowsMobile.PocketOutlook; private void showAccounts(object sender, EventArgs e) {    OutlookSession session = new OutlookSession();    MessageBox.Show(session.SmsAccount.Name);    foreach (EmailAccount account in session.EmailAccounts)    {        MessageBox.Show(account.Name);    } } Hope this helps. Yeap, C# is way easier.  However note that in .NetCF, the SMS account is separate from the collection of E-mail accounts.

  Thanks for the post. Keep'em coming. But could you go a little more into detail and cover what's not yet in the SDK docs, say, something about the databases used by MAPI, similar to the article by Werner "Menneisyys" Ruotsalainen on mail-related information? In particular, how could I troubleshoot the mystery of disappearing email accounts (after radio failure).

  Henry, the databases used by MAPI are not going to be in the SDK docs because this gives us the flexibility to make changes as necessary.   Given that, however, about your bug... I've personally never seen or heard of this bug before, but you can start by using the function that I wrote above. If the account disappeared, it may help you troubleshoot a little bit.

  I've read that Microsoft is going to make public the Outlook/Exchange protocol. Any chance of getting information about this with regards to MAPI on Windows Mobile? http://reddevnews.com/news/devnews/article.aspx?editorialsid=192

• Anonymous
  March 25, 2007
  Bill, MAPI is designed for use with on-board messaging databases, not for network access.  So it's unlikely that MAPI will be extended to access the Outlook/Exchange protocol directly. At least, I haven't heard anything.

• Anonymous

  Thanks for the response Jay! Sorry, let me rephrase the question. Any chance of seeing how Windows Mobile populates these on-board messaging databases over the network by using the low level Outlook/Exchange protocol? We're writing a tool that will proxy this traffic. I realize from the article I referenced that a license will likely need to be acquired. Any help would be really appreciated.

  Thanks Jay for this detailed note. You have suggested that folks should look at mapitags.h (and mapi.h) -- but the most confusion part is that which properties are available in what objects? For example, account name is in message store and not in message itself. There are numerous challenges in MAPI with Windows Mobiles. Appreciate you could cover some of them: Here is the non-exausted list:

1. Dynamic menu insertion (one of the most complex jobs -- menus vanish when you change 'views', there is no good way of knowing which menu is being selected, sub-menus pose their own problems)
2. Inserting menus for certain kinds of accounts
3. Retrieving properties such as From, TO, CC/BCC in POP/Outlook accounts
4. Retrieving message body (HTML, TEXT, MIME)
5. Creating your own form and rendering HTML body
6. Developing outlook plugin and establishing proper event notification etc. More later nitin

  Bill, I am looking into your question - so far I haven't heard anything about APIs to be made public. Nitin - I have ideas for blog topics lined up along those lines.  I agree that if you don't know what you're looking for, mapitags.h isn't going to help. However, hopefully in my future articles I will answer.  I intend to cover:

1. How to read the from/to/text of an SMS (and later on, a POP3/Outlook message. The latter uses a different property).
2. How to add a menu extension (to use with the tool I write in #1). I don't understand what you mean by "developing outlook plugin".  What do you mean by Outlook plugin? a menu extension? Creating your own form and rendering an HTML body is something that is more advanced and there exist demos for, especially if you have the OEM Adaptation Kit.  I'm not sure if there is a demo in the SDK though.

  The error handling in this should be an example of how NOT to handle errors. The CHR macro jumps to a label that is followed by a free. What really needs to be done before exiting is the POOM logoff, which is right before the label. So, we've actually jump right past the one thing that needs to be done to clean up. But wait, it gets better. The free after the error jump is for an item that is never allocated until after all uses of the CHR macro, so it never has any possible use where it is. This sample would be better without any error handling at all.

• Anonymous
  March 27, 2007
  Matthew, The destructor of the IMAPISession would handle that Logoff anyway, so the Logoff call strictly isn't necessary. I included it for illustrative purposes. However, the last FreeProws() is actually necessary, otherwise there will be a leak. Note that the last iteration of the loop will obtain a rowset but not free it.

  How would you forward a message using MAPI? Is there any C++ sample code? Thanks.

• Anonymous
  March 28, 2007
  jayongg, My point about the FreeProws() is that it is needed after the while loop, but not in the error jump. Putting it there implies its needed in some way for cleaning up when there is an error, but it all cases there is a juimp there, prowset will always be NULL. Its good to know the logoff is automatic. In that case, you could just do a clean return in the macro rather than a goto and be done with it.

  Hi Dorel, you can "forward" a message using MailComposeMessage and attach a body/subject - it will bring up a new compose form for the user to fill out. The user will still have to hit Send Hi Matthew. I see your point.  Without turning this into a blog about coding styles.. The CHR()/Error macro implies that all cleanup occurs at the end of the function. A developer can confidently know that any usage of rowset will be cleaned up at the end.  I agree that it isn't necessary in this case (because everything will get cleaned up in the loop).  For me, it's force of habit since it ensures that if I error out of the loop early, I won't leak any rowset.  It's kind of like a poor-man's C++ destructor for cleanup (for the purposes of this article there's no point in writing a class to release on destruction). Thanks for looking at the code though.

  Hi Jay, I have tried MailComposeMessage(), bat cannot manage the attachments that are not downloaded yet on the device (and I don't want to download the attachments on the device). Beside that, I don't want to bother the user with a Message form , and to hit the Send button. I was looking for a MAPI function similar to IMessage::SubmitMessage( ULONG ulFlags ); This imaginary function would work perfectly for me: IMessage::ForwardMessage(ULONG ulFlags, LPADRLIST lpTos); What I want to achieve is to forward messages with attachments to a preset email address. The process would be triggered by the user clicking on a Menu Extension Item on Inbox: "Forward to my MSN account..." Is there any programmatically way to invoke Active Sync to send a "SmartForward" Cmd request to Exchange Active Sync? [for example:  POST /Microsoft-Server-ActiveSync?User=meme&DeviceId=4fa4&DeviceType=PocketPC&Cmd=SmartForward&ItemId=1:3&CollectionId=0a093-1d&SaveInSent=F HTTP/1.1] Thanks for your help.

  Hi Dorel, What exactly have you tried so far?  So you are saying that IMessage::SubmitMessage would work, as long as it allowed you to specify a message to forward, correct? imaginary function: IMessage::ForwardMessage(ULONG ulFlags, LPADRLIST lpTos, DWORD cbEntryIdMessageOriginal, LPENTRYID pEntryIdMessageOriginal) ? Unfortunately there is no public way of doing this.  Here is the issues involved: Activesync messages with Smart Forwarding use a private property to store information about text and attachments.  If you need this public, you will have a stronger case if you have an OEM or operator who would desire this functionality. We can't just publicize this functionality because we haven't tested this property/scenario under all circumstances. I hope this helps. Frankly this does sound like a cool feature to have.

  Cloud, you can't add an MMS account via the XML, only email accounts.  To create an MMS account you need to create a message store using MAPI. as for counting unread messages in an inbox, there is a MAPI property one the MAPI folder that will allow you to do this. looks this up in the SDK.

  > To create an MMS account you need to create a message store using MAPI. Can you give a sequence of operations how to create, for example, MMS account? Let us suppose, we have a MMSTransport.dll -- empty analog of MAPI New Messaging Transport Sample. Then we register it, something like this: ATL::CRegKey mms_trans_key; mms_trans_key.Create( HKEY_LOCAL_MACHINE, _T("Software\Microsoft\Inbox\Svc\MMS") ); mms_trans_key.SetStringValue( _T("Name"), _T("MMS") ); mms_trans_key.SetStringValue( _T("DefMsgClass"), _T("IPM.xMMS") ); mms_trans_key.SetStringValue( _T("DLL"), _T("MMSTransport.dll") ); mms_trans_key.SetDWORDValue ( _T("Port"), 0 ); There are questions:

1. where and when we should create a message store using ICEMAPISession::CreateMsgStore()?
2. how to create MMS account and link it with this message store?
3. what else we should make to view the results in builtin Messaging application GUI? Thank you and please excuse me for my bad english.

  _random, in order to create an MMS account, you should do what you did above, but also set this reg key (found in snapi.h): //////////////////////////////////////////////////////////////////////////////// // MessagingMmsAccountName // Gets the name of the MMS messaging account. #define SN_MESSAGINGMMSACCOUNTNAME_ROOT HKEY_CURRENT_USER #define SN_MESSAGINGMMSACCOUNTNAME_PATH TEXT("System\State\Messages\MMS") #define SN_MESSAGINGMMSACCOUNTNAME_VALUE TEXT("Account Name") To answer your questions:

1. Create message store as early as possible. Obviously you want to do it before the user creates an MMS message (or receives one). ideally on cold boot. Or as part of your cab file install.
2. You will need to create a mail transport as in the sample. If you use the sample, it doesn't work?
3. You will need to create message forms to hook this up with the Messaging GUI.  You will need to do this using native code. Have you looked in the SDK on this topic?

  > _random, in order to create an MMS account, you should do what > you did above, but also set this reg key (found in snapi.h): For experiments, I created separate MMSInstaller.exe as some installer analog: int _tmain( int argc, _TCHAR* argv[] ){ Register_DLLs_and_AccountName(); CreateMMSAccount(); return 0; } I have added this code to Register_DLLs_and_AccountName() function: void Register_DLLs_and_AccountName() { // register MMSTransport.dll {...} // you already saw it (roughly) // register MMSForm.dll {...} // similar as above, I have no questions about it // register MMS Account Name, as you said ATL::CRegKey mms_account_key; mms_account_key.Create( SN_MESSAGINGMMSACCOUNTNAME_ROOT, SN_MESSAGINGMMSACCOUNTNAME_PATH ); mms_account_key.SetStringValue( _T("Account Name"), _T("MMS") ); } Then, I write CreateMMSAccount() function based on MSDN's samples: void CreateMMSAccount() { HRESULT hr = ::MAPIInitialize( NULL ); ASSERT( SUCCEEDED(hr) ); ICEMAPISession * pSession = NULL; hr = ::MAPILogonEx( 0, NULL, NULL, 0, (LPMAPISESSION *)&pSession ); ASSERT( SUCCEEDED(hr) ); IMsgStore * pMsgStore = NULL; hr = pSession->CreateMsgStore( _T("MMS"), &pMsgStore ); ASSERT( SUCCEEDED(hr) ); pMsgStore->Release(); hr = pSession->Logoff(0, 0, 0); ASSERT( SUCCEEDED(hr) ); pSession->Release(); pSession = NULL; ::MAPIUninitialize(); } > 1.

I performed the registrations with MMSInstaller.exe on PPC 5.0 Emulator. Then I made soft reset (to restart native messaging application). Nothing changes in the Messaging GUI... The only account I see is Outlook E-mail. What else I should make or, may be, there are some mistakes in samples above? > 2. You will need to create a mail transport as in the sample. > If you use the sample, it doesn't work? It works... but I don't understand why we need to create account with this schema (as it is described in Windows Mobile 5.0 Pocket PC SDKSamplesCPPWin32Transportdemoreadme.txt): "4) Create a new account: a) Menu->Tools->New Account. b) (E-mail setup 1/5) Enter an email address which will use your custom transport. Click the Next softkey." Why email address? I don't want any e-mail on MMS account :). > 3.

I created simple MMSForm.dll that does nothing except show MessageBox( "It works :)" ); in each method of the IMessageFormEx interface.

  I would like to know how I can retrieve MMS attachments. On my device, when I list the message store I get only Activesync and SMS. So I suppose MMS are stored in the SMS store and indeed I can retrieve the MMS subject using the PR_SUBJECT property but nothing more. How can I get pictures/sounds, ... What is the MMS format and properties, nobody has been able to answer this simple question ...

  Hi Mosfet, Unfortunately, OEMs can provide whatever MMS properties and store messages any way they want - Microsoft doesn't dictate that.  Therefore, MMS message information can be stored in any way. You can contact the MMS providers to find out how they store the data - I believe some might even have an SDK.

  Above I wrote about it. First, I call a function (in installer.exe) with this code (on PPC WM 5.0 Emulator): // register MMS Account Name, as you said ATL::CRegKey mms_account_key; mms_account_key.Create( SN_MESSAGINGMMSACCOUNTNAME_ROOT, SN_MESSAGINGMMSACCOUNTNAME_PATH ); mms_account_key.SetStringValue( _T("Account Name"), _T("MMS") ); Second, I call this function: void CreateMMSAccount() { HRESULT hr = ::MAPIInitialize( NULL ); ASSERT( SUCCEEDED(hr) ); ICEMAPISession * pSession = NULL; hr = ::MAPILogonEx( 0, NULL, NULL, 0, (LPMAPISESSION *)&pSession ); ASSERT( SUCCEEDED(hr) ); IMsgStore * pMsgStore = NULL; hr = pSession->CreateMsgStore( _T("MMS"), &pMsgStore ); ASSERT( SUCCEEDED(hr) ); pMsgStore->Release(); hr = pSession->Logoff(0, 0, 0); ASSERT( SUCCEEDED(hr) ); pSession->Release(); pSession = NULL; ::MAPIUninitialize(); } Then, I make soft reset of the Emulator (thinking it restarts Messaging application). Nothing changes in GUI... I don't know what is the account itself: registry key + some directories? I think that pSession->CreateMsgStore( _T("MMS"), &pMsgStore ) -- will create the Directory. Can you point the MSDN article, where this mechanizm is described? Thank you.

  Great articles on Mobile MAPI, but I do have a couple of questions that I can't seem to find an answer to anywhere:

1. If a message is only partially downloaded (ie has MSGSTATUS_PARTIAL set) what command or commands trigger the full download?  (the equivalent of opening pocket outlook and hitting message download, but programmatic)
2. In WM6 there is now HTML mail support, so I want to display the HTML in say a WebBrowser control...works great except for one problem.  Embedded images (images with a CID tag) are not displayed correctly.  I can manually parse the HTML and after saving the embedded attachments to a temp file reroute the src= param however I was wondering if there was perhaps a callback to allow us to fill in the image bytes of an embedded image?

• Anonymous
  April 29, 2007
  Hi Noel, Regarding HTML Mail - you probably will have to write your own event handler to work with the HTML control to deal with embedded images.  I thought there was a callback mechanism, but I haven't looked at that code in a while... Regarding MSGSTATUS_PARTIAL, downloading a whole message is actually more complicated than just setting a flag.  Depending on the transport, you have to think about downloading attachments, which is done different for HTML mail vs normal attachments, I believe.  With that said, this might work... try setting the MSGSTATUS_REMOTE_DOWNLOAD flag to start out, and MSGSTATUS_REMOTE_DOWNLOAD_ATTACH as well. If that doesn't work, it's hard for me to give any advice without knowing exactly what your app is doing. Thanks, Jay

• Anonymous
  May 07, 2007
  Yes, I figured there was a call to download the rest of the message, the MSGSTATUS_PARTIAL flag is already set by the message (I'm simply reading in the message and seeing that it is set) I want to get the body and perhaps the attachments; I'll try setting the DOWNLOAD flags thanks.

  I would really like to be able to change the automatic checking period for an email account. For example, have no automatic check in the evening and every half hour in the day. For activesync these properties are stored in the registry. So I suppose I am asking how do you programmatically change the check period of an email account. Cheers

  Hi Chris, I assume when you say "email account" you mean POP/IMAP accounts.  Unfortunately, there isn't a concept of peak and non-peak schedules with POP/IMAP accounts - I don't believe this is in the UI.

• Anonymous

  This is true. I was refering to IMAP/POP. I was wondering if it were possible to programmatically set it and therefore, I could use the notification queue to give me the peak/off peak behaviour.

  Hi Jay, Off late i have been playing with windows mobile 5.0 apis mostly with the apis available with pocketoutlook namespace (C#). This is what i am trying to implement: I will be having a separate application that has similar  UI as the Email compose form along with additional controls. Once user clicks on save/send i want the EmailMessage to be saved in the "Outbox" folder. After looking to the managed apis i did not find any apis that allow me to deal with folders other then contacts, tasks and appointments. I also went through "SendMail" CPP example available with the sdk which does something similar to what i want. However i was wondering if this is possible in C#. Any help of guidance in this respect will be appreciated. -Amit

  Hi, the PR_BODY is a stream, not a string, so you will have to open a stream, not get the property.

  This can vary... are you trying to open a form? if so, MailComposeMessage with the MMS account should suffice.  Otherwise you will need to work with the vendor of the MMS provider - Microsoft doesn't create the MMS client.

  I have a MAPI application that gets notified when there is new mail coming. What I would like to do is automatically to accept/deny a meeting invite base based on some specific properties of the meeting invite message. I can check those mesage's properties, but I don't know how to do the accepting/denying. Could you let me know which MAPI interface should I use for this purpose? If it is possible, some small code would be great. Thanks, Rocky

  Hi Anton, PR_RTF_COMPRESSED is not public. PR_BODY and PR_BODY_HTML are both streams, not strings. You will need to open them into IStream's and proceed from there. Hope this helps!

  Hi Hendrik, try this: from the message store, get the PR_IPM_SUBTREE_ENTRYID property, cast it to IMAPIFolder. The call IMAPIFolder::GetHierarchyTable, and for each entry in the table you can the PR_DISPLAY_NAME as well as boolean listing whether it has subfolders (PR_SUBFOLDERS).

  Hello, I need help with some iPAQs. We own approx. 100 x HP iPAQ 2210, 30 x HP iPAQ 2410 and 50 x HP iPAQ 2490 iPaqs. Were having trouble using MAPI to retrieve e-mails GUIDs in order to make remote configurations for our Sales Force Team. If we follow MSs documentation, the code works properly in Visual Studios emulator, but not in our equipment. We have found that the iPaqs have a different value for PR_CE_UNIQUE_STORE_ID when we query the property pRows->aRow 0 lpProps ePR_CE_UNIQUE_STORE_ID .ulPropTag (MS says it must be 0x81130048 but the iPaq returns another value). And even if we change this value to match iPaq`s one, the GUID returned does not points to a valid e-mail account and thus we cannot use it to manage them. We need to solve this ASAP, since we have a deadline from our Audit team and this problem is hindering the delivery of the solution. Please if someone have any idea how to solve it, please send me an e-mail: michelle.rosario@garoto.com.br Best Regards. Michelle Santos

• Anonymous
  March 26, 2008
  Michelle, I asked a colleague and this is what he said: "The value of PR_CE_UNIQUE_STORE_ID should not be different for different devices. It’s more likely that the property query is returning a different proptag value because the property cannot be found. (I think the value is PT_ERROR.) From what I can tell, the property only exists on accounts that are created via CSP. Maybe they are configuring the accounts differently on the iPaqs than on the emulator?" Thanks, -Luis Cabrera

  Hi Selva, you can turn off the notification using PR_CE_NO_NOTIFICATION. Set this in ulPropTag field of 'SPropValue' and invoke SetProps. You would see the message notification not being displayed.

  Jay, Could you please help me with setting status of the outgoing SMS. I could dig out 'PR_MSG_STATUS' field as ulPropTag, but could not find an appropriate one for 'Value.ul' Appreciate your help. Thanks!

  How do we delete an account? I created email account that appears as Other (POP/IMAP). How can I delete it through API (C/C++) or .NET? I can see that it can be deleted from messaging application but couldn't find any API.

  Hi :) We have problem with retrieving MMS messages. We are able to get subject, phone nr, date. The main problem is we aren't able to get body like photo file. In our work we use a Palmtop(QTEK S100) with operating system Windows Mobile 2003 SE and library CEMAPI in C++. I know I can use IMessage... but i don`t know how to get a pointer to IMessage:( http://msdn.microsoft.com/en-us/library/bb446198.aspx Can Any one help please?

  I use: SPropValue rgProps[4] = {0}; int rgValues = 0; rgProps[rgValues].ulPropTag = PR_CE_HIDE_FROM_TODAY_PAGE; rgProps[rgValues].Value.b = TRUE; rgValues++; // prevent default notification rgProps[rgValues].ulPropTag = PR_CE_NO_NOTIFICATION; rgProps[rgValues].Value.b = TRUE; rgValues++; pMsg->SetProps(rgValues, rgProps, NULL); and the default notification sounds still is playing... note: when I add to the above: rgProps[rgValues].ulPropTag = PR_MESSAGE_FLAGS; rgProps[rgValues].Value.ul  = MSGFLAG_READ; the sound does not play. of course (?)

  Of course, I undestand, that PR_CE_NO_NOTIFICATION is for pop-up (bubble) notification. but how to prevent from default sound notification too? I think about MRC_HANDLED_DONTCONTINUE but when someone uses also another mapi-rule application, this state breaks that 3rd parts function too, isn't it?

  Hi, I want to create a new message store and see it displayed alongside the existing message stores in the Messaging application. I call CreateMsgStore and it returns OK, and I can then enumerate using GetMsgStoresTable and I see my new store has been created. I don't however see my message store displayed in the messaging application. Is there something else I need to do?  Are there registry keys I also need to set?

  Hi Jay/all, If I tap into mapi (cemapi.dll) from managed code (C#) using com interop is this supported and/or wise.  I note that the desktop mapi libraries are not supported by MS when used with managed code.  If it is 'ok' to access cemapi.dll from managed C# then does anyone have any examples of how to call, say, IMAPITable.SetColumns (I've got code working as far as IMAPISession.GetMsgStoresTable but I'm stuck trying to define my prop array in C# for the SetColumns call).  Any help would be hugely appreciated - thanks very much!
