CRMActivity.RevokeAccess Method

  • Article

The RevokeAccess method revokes access rights to the activity for the specified security principal. This method also applies to all child objects of the activity. For all child objects, if the caller does not have share privileges for those object types or share rights to the objects, access to the child objects is not revoked. As a result, the owner of the object or a user who shares the object with share rights automatically has share rights to all child objects of the activity. In this case, only the lack of privileges to a particular object type prevents access to the child objects from being revoked.

Syntax

[Visual Basic .NET]
Public Sub RevokeAccess(
  ByVal Caller As CUserAuth,
  ByVal ActivityId As String,
  ByVal Revokee As CSecurityPrincipal
)

[C#]
public void RevokeAccess(
  CUserAuth  Caller,
  string  ActivityId,
  CSecurityPrincipal  Revokee
);

[C++]
public: void RevokeAccess(
  CUserAuth*  Caller,
  String*  ActivityId,
  CSecurityPrincipal*  Revokee
);

Parameters

Caller

Specifies the identity of the caller. The caller must have the prvShareActivity privilege to perform this action. See CUserAuth.

ActivityId

Specifies the ID of the activity.

Revokee

Specifies the security principal for which access is to be revoked. See CSecurityPrincipal.

Return Value

No return value.

Remarks

If there is an error, SOAP throws an exception and the error message is reported in System.Web.Services.Protocols.SoapException.Detail.OuterXml.

All IDs passed to the platform are GUIDs wrapped in braces. For example: {6522D89A-A752-4455-A2B0-51494C6957C3}

Example

[C#]
// strServer should be set with the name of the platform Web server
string strServer = "myservername";

// virtualDirectory should be set with the name of the Microsoft CRM
// virtual directory on the platform Web server
string virtualDirectory = "mscrmservices";
string strDir = "https://" + strServer + "/" + virtualDirectory + "/";

// BizUser proxy object
Microsoft.CRM.Proxy.BizUser bizUser = new Microsoft.CRM.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";

// CRMActivity proxy object
Microsoft.CRM.Proxy.CRMActivity activity = new Microsoft.CRM.Proxy.CRMActivity ();
activity.Credentials = System.Net.CredentialCache.DefaultCredentials;
activity.Url = strDir + "CRMActivity.srf";

string strErrorMsg;
string strActivityId = "{33A081D8-ABFF-4103-9E9B-DB0A4B1FD48E}";
string strUserId = "{ECF99EF1-3858-4E06-ABD9-EBFE526BF9FF}";

try
{
   Microsoft.CRM.Proxy.CUserAuth userAuth = bizUser.WhoAmI();

   // Create a new security principal
   Microsoft.CRM.Proxy.CSecurityPrincipal securityPrincipal = new Microsoft.CRM.Proxy.CSecurityPrincipal();
   securityPrincipal.Id = strUserId;
   securityPrincipal.Type = Microsoft.CRM.Proxy.SecurityPrincipalType.sptUser;

   uint rights = Microsoft.CRM.Flags.AccessRights.CRM_ACCESS_READ;
   
   // Grant access to the activity
   activity.GrantAccess(userAuth, strActivityId, rights, securityPrincipal);

   // Now revoke access
   activity.RevokeAccess(userAuth, strActivityId, securityPrincipal);
}
catch (System.Web.Services.Protocols.SoapException err)
{
   // Process the platform error here
   strErrorMsg = ("ErrorMessage: " + err.Message + " " + err.Detail.OuterXml + " Source: " + err.Source );
}
catch (Exception err)
{
   // Process other errors here
   strErrorMsg = ("ErrorMessage: " + err.Message );
}
