EDIT: I just can't make a working about box without it closing the whole program.
See attachment in my later reply.

I can't find the code attachment in your post. It would be easier for us to help you if you gave us something to work with, because we don't know what you have done.

Code:
proc WindowProc, hWnd, uMsg, wParam, lParam
local pt:POINT
mov eax, [uMsg]
mov ebx, [wParam]

cmp ebx, IDM_ABOUT
jne @f
invoke ShowWindow, [hwndabout],SW_SHOW
jmp .returning
@@:
cmp ebx, IDM_EXIT
je exit
cmp eax, WM_DESTROY
jne @f
;invoke ShowWindow, [hwndabout],SW_SHOW    When pressing the x, it should just hide itself
jmp exit ;if i didn't put this here, I would always have to kill the process
@@:
cmp eax, WM_SHELLNOTIFY
jne .returning
cmp     [lParam],WM_RBUTTONDOWN
jne      .returning
lea     eax,[pt]
invoke GetCursorPos, eax
invoke SetForegroundWindow,[hwnd]
invoke TrackPopupMenu, [hMenu], TPM_LEFTALIGN,[pt.x], [pt.y],0,[hwnd],0

.returning:
invoke DefWindowProc,[hWnd],[uMsg],[wParam],[lParam]

ret
endp     

I don't want the main invisible msg only window [hwnd]to be closed when I close the other [hwndabout]

rohagymeg: I can't compile your code. It appears to be incomplete.

I made it compileable. Please show me how one can make it so when you close the about box/window, the program doesn't close, only the window hides.

You must process WM_CLOSE message, not WM_DESTROY.
Example:
Code:
cmp eax, WM_CLOSE
je  .closeit
;........
;..........
.closeit:
        invoke ShowWindow, [hWnd], SW_HIDE
        xor    eax, eax
        ret
    


Note that you should not pass WM_CLOSE to DefWindowProc, because it will destroy the window.
Also, there are many flaws in your code, including the whole structure and source layout.
If this is intended to become usable program, you have to clean the mess and make it more readable.

Thanks for the help! I know I am a beginner, but I removed a lot of things like comments and unrelated code for the simplicity of the example. I'm reading msdn all day like crazy:) When the main functions are ready, I will clean it up.
