In MFC application
I Created a Dialog with no Border and I put one Picture control on the dialog with one bitmap image

so I wanted to use that picture box as title bar

it means when mouse button is down on the picture and mouse is moved or dragged The window is also be moved

What should I do?

What I have tried:

LRESULT CMoveWinUsingPicDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
	if( message == (WM_RBUTTONDOWN) )
	{
		//I think Here I can do something or suggest any other best place or solution
	}
}
