Buttons work but don't show up until clicked on.

[Aquacold]

I'm currently making a Flash Card Program and just got to making the GUI. Most of the windows have been set up and once done I will be adding the functionality of the program. My study window worked as a wrote it originality but something changed between then and now and I can't pinpoint it. There are two buttons and one static field that are no longer appearing when i switch to that window. The two buttons only appear once I have clicked on their location, they still work. The static field no longer appears though. How can I fix this?

P.S. There is a lot of code so if you don't want to be bothered turn back now!

Note - I won't include the card and deck cpp/h files. I hopefully commented out or removed everything relevant to those files.

You should, after creation (CreateWindow), by order:

1. Show all the little windows (Buttons and so on)
2. Show the window itself.

It will look like:

// All your CreateWindowEx...
ShowWindow(g_CardMaker,SW_SHOW);
ShowWindow(g_Study,SW_SHOW);
//... and so on. Do NOT use nCmdShow for these windows.
ShowWindow(hwndMain,nCmdShow); // But do for this window.
UpdateWindow(hwndMain);

Like this right?

ShowWindow(g_ReturnToMainS, SW_SHOW);
ShowWindow(g_CardNextButton, SW_SHOW);

Still a no go. It worked before, I just have no idea what I changed.

OK I feel like an idiot, a dumb mother trucker.

	g_CardExtraField = g_TextBox = CreateWindowEx(0, "STATIC" , "",
         WS_CHILD | WS_VISIBLE, 0, 222, 400, 40, hwndStudy,
		 (HMENU) 12, hInstance, NULL);

	//EditMenuAddCardsWindow (hwndEditAddCards)

	g_AddCardsInfo = CreateWindowEx(0, "STATIC" , "",
         WS_CHILD | WS_VISIBLE, 0, 222, 400, 40, hwndStudy,
		 (HMENU) 16, hInstance, NULL);

I have TWO static fields doing the same thing. After I fixed that I replaced the buttons after it and it overlapped fine. I had it that why originality but I copied the top static field so I didn't have to write it again for the next window. Thanks anyway man.
