Deletes the current message.
HRESULT DeleteMessage(
LPMAPIVIEWCONTEXT pViewContext,
LPCRECT prcPosRect
);
Parameters
pViewContext
[in] A pointer to a view context object.prcPosRect
[in] A pointer to a RECT structure that contains the current form's window size and position. The next form displayed also uses this window rectangle.
Return Value
S_OK
The call succeeded and has returned the expected value or values.MAPI_E_NO_SUPPORT
The operation is not supported by this message site.
Remarks
A form object calls the IMAPIMessageSite::DeleteMessage method to delete the message that the form is currently displaying.
Notes to Callers
Following the return of DeleteMessage, form objects must check for a new message and then dismiss themselves if none exists. To determine whether the message DeleteMessage acted on was deleted or moved to a Deleted Items folder, a form object can call the IMAPIMessageSite::GetSiteStatus method to determine whether the DELETE_IS_MOVE flag was returned.
Notes to Implementers
If a form viewer's implementation of the DeleteMessage method moves to the next message after it deletes a message, the implementation should call the IMAPIViewContext::ActivateNext method and pass the VCDIR_DELETE flag before performing the actual deletion. If a form viewer's implementation of DeleteMessage moves the deleted message (for example, to a Deleted Items folder), the implementation must save changes to the message if the message was modified.
A typical implementation of DeleteMessage performs the following tasks:
If the implementation is moving the message, it calls the IPersistMessage::Save method, passing NULL in the pMessage parameter and TRUE in the fSameAsLoad parameter.
It calls the IMAPIViewContext::ActivateNext method, passing the VCDIR_DELETE flag in the ulDir parameter.
If the ActivateNext call fails, it returns. If ActivateNext returns S_FALSE, it calls the IPersistMessage::HandsOffMessage method.
It deletes or moves the message.
To obtain the RECT structure used by a form's window, call the Windows GetWindowRect function.
