DrawTitleButton

Draw your custom buttons where the caption would normally place them. Position doesn't matter. In the WM_COMMANDsection of your callback, use ShowWindow(hwnd, SW_MAXIMIZE) and ShowWindow(hwnd, SW_RESTORE). That's all there is to it.

Custom Button

1) Do not use BeginPaint/EndPaint in WM_ERASEBKGND. Move that code in a WM_PAINT handler.

2) Use SetWindowLong and the GWL_USERDATA index for storing the button state (UP or DOWN) and use GetWindowLong for retrieving the current state.

3) Use SetCapture for capturing the mouse, starting with WM_LBUTTONDOWN. Update the state of the button (UP or DOWN) according to mouse position

4) Use RedrawWindow when you need painting to occur
