Resurrecting MFC/Visual Studio 6.0 project in VS2010
mfc, visual-c++, visual-studio-2010
Solution
Change your ON_MESSAGE macro to ON_MESSAGE_VOID. The ON_MESSAGE macro returns a LRESULT from receiving WPARAM and LPARAM arguments. Your compiler error message states that your OnFinished() method is void arguments returning void. That's what the ON_MESSAGE_VOID macro handles.

Problem
I am trying to build a MFC Visual Studio 6.0 project in Visual Studio 2010. The compiler gives me an error: error C2440: 'static_cast' : cannot convert from 'void (__thiscall ProgressDialog::* )(void)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)' //--------------------------------- // Message map BEGIN_MESSAGE_MAP(ProgressDialog, CDialog) ON_BN_CLICKED(IDC_CANCEL, OnCancelClicked) ON_MESSAGE(MSG_FINISHED, OnFinished) END_MESSAGE_MAP() Any suggestions - ?
