Let's say you have a standard default window with 2 buttons. I have setup the buttons to interactively display text when being pushed, but I want to make the buttons disappear, it's possible right??? Little help?

The ShowWindow should do what you want. Send SW_HIDE to hide a button window, SW_SHOW to restore it.

.IF ax==ButtonID
shr eax,16

.IF ax==BN_CLICKED
invoke SendMessage,hWnd,WM_COMMAND,IDM_GETTEXT,0
INVOKE ShowWindow,ButtonID,SW_HIDE
INVOKE UpdateWindow,ButtonID
invoke InvalidateRect, hWnd,NULL,TRUE
.ENDIF

.ENDIF

This is what I have for my button being pushed, but it doesn't do anything... I'm I implementing the SW_Hide wrong???

I created the button in WM_Create

ELSEIF uMsg==WM_CREATE
invoke CreateWindowEx,NULL, ADDR ButtonClassName,ADDR ButtonText,\
WS_CHILD or WS_VISIBLE or BS_DEFPUSHBUTTON,\
75,70,140,25,hWnd,ButtonID,hInstance,NULL
mov hwndButton,eax
invoke CreateWindowEx,NULL, ADDR ButtonClassName,ADDR ButtonText2,\
WS_CHILD or WS_VISIBLE or BS_DEFPUSHBUTTON,\
225,70,140,25,hWnd,ButtonID2,hInstance,NULL
mov hwndButton,eax

Yah I believe it's a resource ID. How would I create a button manually? Where would that code go to manually create a button?

hi Framework welcome to the board,

anyways you are doing something minor. instead of using your button controls ID (ButtonID) you need to use the buttons handle (hwndButton). so it should look something like this:

.IF uMsg == WM_COMMAND

      .if lParam == hwndButton

         mov eax,wParam

         shr eax,16

            .if ax == BN_CLICKED 

               invoke SendMessage,hWnd,WM_COMMAND,IDM_GETTEXT,0 

               invoke ShowWindow,hwndButton,SW_HIDE

            .endif

       .end

For each call to CreateWindowEx you get the handle of the window (button) returned in eax. That's what the mov hwndButton,eax does -- it saves the window handle for future reference. However, you're overwriting the first window handle with the second mov hwndButton,eax. The solution is simply to declare another variable that will accept the second button handle, like hwndButton2. (Something more meaningful will make your code easier to read and follow... like hPlayButton or hStopButton, or whatever your buttons do).

You can use these handles for ShowWindow instead of ButtonID and they will Show/Hide the corresponding button.
