MFC - edit File-Open action

Question

I created a MFC application using the MFC app wizard, with the SDI template. Currently, everything is unchanged. So all my classes are the ones generated by the wizard, straight-forward.

Now I want to edit what the File->Open... menu does. Where do I edit this?

Answer 1

If you don't already have one add a message handler in your app class, like this in the message map:

ON_COMMAND(ID_FILE_OPEN, OnMyFileOpen)

void CXXApp::OnMyFileOpen()
{
...
}
