  [in] LPOLEUIINSERTOBJECTW unnamedParam1
);

Parameters

[in] unnamedParam1

Pointer to the in-out OLEUIINSERTOBJECT structure for this dialog box.

Return value

Standard Success/Error Definitions

Return code Description
OLEUI_FALSE
 Unknown failure (unused).
OLEUI_OK
 The user pressed the OK button.
OLEUI_SUCCESS
 No error, same as OLEUI_OK.
OLEUI_CANCEL
 The user pressed the Cancel button.
 

Standard Field Validation Errors

Return code Description
OLEUI_ERR_STANDARDMIN
 Errors common to all dialog boxes lie in the range OLEUI_ERR_STANDARDMIN to OLEUI_ERR_STANDARDMAX. This value allows the application to test for standard messages in order to display error messages to the user.
OLEUI_ERR_STRUCTURENULL
 The pointer to an OLEUIXXX structure passed into the function was NULL.
OLEUI_ERR_STRUCTUREINVALID
 Insufficient permissions for read or write access to an OLEUIXXX structure.
OLEUI_ERR_CBSTRUCTINCORRECT
 The cbstruct value is incorrect.
OLEUI_ERR_HWNDOWNERINVALID
 The hWndOwner value is invalid.
OLEUI_ERR_LPSZCAPTIONINVALID
 The lpszCaption value is invalid.
OLEUI_ERR_LPFNHOOKINVALID
 The lpfnHook value is invalid.
OLEUI_ERR_HINSTANCEINVALID
 The hInstance value is invalid.
OLEUI_ERR_LPSZTEMPLATEINVALID
 The lpszTemplate value is invalid.
OLEUI_ERR_HRESOURCEINVALID
 The hResource value is invalid.
 

Initialization Errors

Return code Description
OLEUI_ERR_FINDTEMPLATEFAILURE
 Unable to find the dialog box template.
OLEUI_ERR_LOADTEMPLATEFAILURE
 Unable to load the dialog box template.
OLEUI_ERR_DIALOGFAILURE
 Dialog box initialization failed.
OLEUI_ERR_LOCALMEMALLOC
 A call to LocalAlloc or the standard IMalloc allocator failed.
OLEUI_ERR_GLOBALMEMALLOC
 A call to GlobalAlloc or the standard IMalloc allocator failed.
OLEUI_ERR_LOADSTRING
 Unable to call LoadString for localized resources from the library.
OLEUI_ERR_OLEMEMALLOC
 A call to the standard IMalloc allocator failed.
 

Function Specific Errors

Return code Description
OLEUI_ERR_STANDARDMAX
Errors common to all dialog boxes lie in the range OLEUI_ERR_STANDARDMIN to OLEUI_ERR_STANDARDMAX. This value allows the application to test for standard messages in order to display error messages to the user.
OLEUI_IOERR_LPSZFILEINVALID
The lpszFile value is invalid or user has insufficient write access permissions.This lpszFile member points to the name of the file linked to or inserted.
OLEUI_IOERR_PPVOBJINVALID
 The ppvOjb value is invalid. This member points to the location where the pointer for the object is returned.
OLEUI_IOERR_LPIOLECLIENTSITEINVALID
 The lpIOleClientSite value is invalid. This member points to the client site for the object.
OLEUI_IOERR_LPISTORAGEINVALID
 The lpIStorage value is invalid. This member points to the storage to be used for the object.
OLEUI_IOERR_SCODEHASERROR
 The sc member of lpIO has additional error information.
OLEUI_IOERR_LPCLSIDEXCLUDEINVALID
 The lpClsidExclude value is invalid. This member contains the list of CLSIDs to exclude.
OLEUI_IOERR_CCHFILEINVALID
 The cchFile or lpszFile value is invalid. The cchFile member specifies the size of the lpszFile buffer. The lpszFile member points to the name of the file linked to or inserted.

Remarks

OleUIInsertObject allows the user to select the type of object to be inserted from a list box containing the object applications registered on the user's system. To populate that list box, OleUIInsertObject traverses the registry, adding every object server it finds that meets the following criteria:

  • The registry entry does not include the NotInsertable key.
  • The registry entry includes an OLE 1.0 style Protocol\\StdFileEditing\\Server key.
  • The registry entry includes the Insertable key.
  • The object's CLSID is not included in the list of objects to exclude (the lpClsidExclude member of OLEUIINSERTOBJECT).
By default, OleUIInsertObject does not validate object servers, however, if the IOF_VERIFYSERVEREXIST flag is included in the dwFlags member of the OLEUIINSERTOBJECT structure, OleUIInsertObject verifies that the server exists. If it does not exist, then the server's object is not added to the list of available objects. Server validation is a time-extensive operation and is a significant performance factor.

To free an HMETAFILEPICT returned from the Insert Object or Paste Special dialog box, delete the attached metafile on the handle, as follows:

void FreeHmetafilepict(HMETAFILEPICT hmfp)
{
    if (hmfp != NULL)
    {
        LPMETAFILEPICT pmfp = GlobalLock(hmfp);

        DeleteMetaFile(pmfp->hMF);
        GlobalUnlock(hmfp);
        GlobalFree(hmfp);
    }
    else
    {
        // Handle null pointers here.
        exit(0);
    }
}

Note

The oledlg.h header defines OLEUIINSERTOBJECT as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
