I use Leadtools 15 document image and VisualStudio 6.0
WindowProc(UINT message, WPARAM wParam, LPARAM lParam){
      switch(message){
            case WM_COMMAND:
                  switch(HIWORD(wParam)) {
                       case L_ILN_KEYDOWN:
                             AfxMessageBox(TEXT("KeyDown!!"));
                       break;
                  }
      }
}

Do not working the MessageBox, Why?

This
notification code is used in our Main API demo. Please see the WM_COMMAND processing inside the BrowseDlgProc() function in the file

LEADTOOLS15\Examples\API\MainDemo\Frame.cpp

If
you can't get it to work, put your code in a small sample project (not your full application) that isolates the problem in a ZIP or RAR file.
You
can either attach the project here or send it to support@leadtools.com and mention this post.

If you attach the project here, make sure that you do not include any unlock keys and do not hit preview when attaching.
