i would like to achieve to get my transparent window over another, but dont want to lose z-order, so i need to force my hud to be always the 2nd in z-order (to be the top of a specific window). Is there a good workaround for this?

I'm not exactly sure of your question but if you change any window position Z-Order will always change with it, there is no work-a-around to force one window over another without changing Z-Order. If you know both window handles you can ensure the one you want at the top of the Z-Order remains there by checking if it is still in the foreground using the GetForegroundWindow function. You can even organise them in Z-Order if desired providing you know the window handles.

If GetForegroundWindow_() <> hWnd                                                 ; Check if the window is in the foreground (top window in Z-Order)

  SetWindowPos_(hWnd,#HWND_TOPMOST,0,0,0,0,#SWP_NOMOVE|#SWP_NOSIZE)               ; If it's no longer in the foreground set it TopMost again

EndIf
