Ravi, Are you talking about a Windows message:
#define MYMESSAGE WM_APP+1
... or something else?

Hi Ravi, I don't know if there's a language problem here, but I'm totally
confused over what you need to know.

User defined messages.. Hi Dave, Sorry for not making it clear.
I wanna use a user defined message in my ATL application.
I want to post my own message.
I did like the following way..
#define WM_STARTRECORDING (WM_USER+100)
//in the message map
BEGIN_MSG_MAP(CRecord)
MESSAGE_HANDLER(WM_STARTRECORDING,OnStartRecording)
END_MSG_MAP()
LRESULT OnStartRecording(WPARAM w, LPARAM p)
{
MessageBox(NULL,"start recording","Record",MB_OK);
Quote: }
But I m not able to build this code.. I m getting error's So please can you tell me how to do this in ATL ?? I did this in MFC by
changing the macro ..it worked fine ..
Please kindly reply me ..
thanking you,
Ravi

User defined messages.. Hi Ravi, The signature for message handlers should be:
LRESULT OnStartRecording(UINT uMsg, WPARAM w, LPARAM p, BOOL& bHandled)
Hope that helps,

User defined messages.. You've changed the signature in the declaration, but forgot to do that in the implementation. Change it in all places where OnStartRecording appears -- With best wishes, Igor Tandetnik "For every complex problem, there is a solution that is simple, neat,
