OleUICanConvertOrActivateAs function (oledlg.h)

  • Article

Determines if there are any OLE object classes in the registry that can be used to convert or activate the specified CLSID from.

Syntax

BOOL OleUICanConvertOrActivateAs(
  [in] REFCLSID rClsid,
  [in] BOOL     fIsLinkedObject,
  [in] WORD     wFormat
);

Parameters

[in] rClsid

The CLSID of the class for which the information is required.

[in] fIsLinkedObject

TRUE if the original object is a linked object; FALSE otherwise.

[in] wFormat

Format of the original class.

Return value

This function returns TRUE if the specified class can be converted to another class; FALSE otherwise.

Remarks

OleUICanConvertOrActivateAs searches the registry for classes that include wFormat in their \Conversion\Readable\Main, \Conversion\ReadWriteable\Main, and \DataFormats\DefaultFile entries.

This function is useful for determining if a Convert... menu item should be disabled. If the CF_DISABLEDISPLAYASICON flag is specified in the call to OleUIConvert, then the Convert... menu item should be enabled only if OleUICanConvertOrActivateAs returns TRUE.
