Windows 7 Theme isn't being applied to my simple win32 program.

Hey guys,

I am just starting to learn how to program with the win32 API so that I can make some GUI's for my programs instead of having them all just be console applications. So far everything has been going well, but now that I am starting to add controls I have noticed that they are not in the windows 7 theme.

Here is a simple program that I created to make a window with a button on it. The window has the look of a windows 7 window however the button does not.

I am currently using Code::Blocks 12.11 with the GNU GCC Compiler and my operating system is Windows 7.

    }
    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, INT nCmdShow) {
HWND hwndMain;

MSG Msg;

wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;

wc.lpszMenuName = NULL;
wc.lpszClassName = g_ClassName;

if (!RegisterClassEx(&wc)) {
    MessageBox(NULL, "Failed to register window class!", "ERROR!", MB_OK | MB_ICONWARNING);
    return 0;
}



hwndMain = CreateWindowEx(
    WS_EX_CLIENTEDGE,
    g_ClassName,
    "Controls Test",
    WS_OVERLAPPEDWINDOW,
    CW_USEDEFAULT, CW_USEDEFAULT, 500, 500,
    NULL, NULL, hInstance, NULL);



if (hwndMain == NULL) {
    MessageBox(NULL, "Failed to create window!", "ERROR!", MB_OK | MB_ICONWARNING);
    return 0;
}

ShowWindow(hwndMain, nCmdShow);
UpdateWindow(hwndMain);

while (GetMessage(&Msg, NULL, 0, 0) > 0) {
    TranslateMessage(&Msg);
    DispatchMessage(&Msg);
}
}


Does anyone know why this is happening or how to fix it? Any help would be appreciated!

Thanks!
