I am converting a VC++6.0 project to Visual Studio 2008 (enroute to 2014). I am encountering the above error.

Here is my code snippet:

BEGIN_MESSAGE_MAP(CImportProjectDlg, CDialog) //{{AFX_MSG_MAP(CImportProjectDlg) ON_WM_SIZE() ON_WM_GETMINMAXINFO() ON_WM_SIZING() ON_WM_PAINT() ON_WM_NCHITTEST() ON_BN_CLICKED(IDC_MERGE_IN, OnAdd) ON_BN_CLICKED(IDC_MERGE_OUT, OnRemove) ON_BN_CLICKED(IDC_IMPORTPROJECT_CLEARALL, OnClearAll) ON_BN_CLICKED(IDC_IMPORTPROJECT_APPLY, OnApply) ON_BN_CLICKED(IDCANCEL,OnCancel) //}}AFX_MSG_MAP END_MESSAGE_MAP()

And the error is indicated on the ON_WM_NCHITTEST() line.

Very puzzling.

The correct signature for OnNcHitTest handler is afx_msg LRESULT OnNcHitTest(CPoint);. You have it return UINT instead of LRESULT.

It is unclear to me how and where to change the UINT into LRESULT.
CImportProjectDlg has a method named OnNcHitTest. This method is currently defined to return UINT. Change it to return LRESULT.
I feel a little out of my depth.... do I change the declaration: UINT CImportProjectDlg::OnNcHitTest(CPoint point) to LRESULT. or do I change the return code to LRESULT?
You change the return type from UINT to LRESULT, so the declaration becomes LRESULT CImportProjectDlg::OnNcHitTest(CPoint point)
The function is likely declared in an .h file, and defined in a .cpp file. You've updated it in one place but not the other. Update both.

If you need to let the source code compiled both on VC6 and vs2008 (unfortunately), you may use _MSC_VER to handle it.

Full list here

#if _MSC_VER >= 1500 // For vs2008+ LRESULT #else UINT #endif CImportProjectDlg::OnNcHitTest(CPoint point)
