Porting C to MFC

Posted on 1998-11-23

I am porting my C to MFC, now I face a problem, i.e. retrieving the wParam and lParam. In C, I have a standard Windows Procedure passing parameters of Message, wParam, and lParam. I can then make use of these wParam and lParam.

In MFC, I use MESSAGE_MAP to map my private message (not Standard Windows' message). Here, how can I retrieve the wParam and lParam parameters that passed to my private message?

#define MY_MESSAGE (WM_USER + 1)


  if (wParam==ONE_PARAMETER)

Any help will be very much appreciated!!

Your CMainFrame::OnMyMessage should actually be CMainFrame::OnMyMessage(WPARAM wParam, LPARAM lParam)...

Map Entry
ON_MESSAGE( <message>, <memberFxn> )

Function Prototype
afx_msg LRESULT memberFxn(WPARAM, LPARAM);
