Add a handler for that key combination and do nothing there.

Handle the WM_SYSKEYDOWN message and simply return 0 for wParam==VK_SPACE. WM_SYSKEYDOWN is received instead of WM_KEYDOWN always when the alt is held down, (or when the F10 is pressed). If the alt+Space handling is in your accelerator table then you have to put special handling code to your message loop that drops this WM_SYSKEYDOWN msg before calling TranslateMessage() or DispatchMessage() or something else.

Is the problem just alt-space or does it relate to the entire system menu (even when accessed by the mouse?) In the first case, just discard the WM_SYSKYDOWN for "space", (but the sysmenu can be invocate by other keywords or by the mouse) In the second case, make your window without the WS_SYSMENU style.

If you just want to disable the system menu by pressing keys (but you want to allow it by mouse clicks) then the best solution is to return zero from WM_SYSCOMMAND when wParam==SC_KEYMENU. This disables the system menu for ALT+SPACE, ALT+ALT_RELEASE+DOWN, F10+F10_RELEASE+DOWN, and should disable for all other combinations too.

It might actually be useful to the OP if you respond to him instead of everyone replying to him.

What OP stands for? I replied to the previous message because my reply was in relation with that.

OP = Original Poster. Your answer adds information to my answer respect to what the OP wanted, but it is not itself a response to me since it is not me having the problem. But -if you answer to me- the system will notify myself, and the OP (that wants to know the solution) will never know until he will visit this page randomly later (may even be never, if he already solved somehow the problem).
