    maximizing the window

    Working with my WM_CREATE message, I do a ShowWindow(hwnd,SW_MAXIMIZE), which resizes the window to the maximized size and position when it starts up. The strangeness is that the maximize button in the corner is still visible instead of the downsize button. Is this normal?

    Thanks.

    post your code..... this works as expected....

    Code:
    #include "stdafx.h"
    #include "tester.h"
    #define MAX_LOADSTRING 100
    
    // Global Variables:
    HINSTANCE hInst;								// current instance
    TCHAR szTitle[MAX_LOADSTRING];					// The title bar text
    TCHAR szWindowClass[MAX_LOADSTRING];			// the main window class name
    
    // Forward declarations of functions included in this code module:
    ATOM				MyRegisterClass(HINSTANCE hInstance);
    BOOL				InitInstance(HINSTANCE, int);
    LRESULT CALLBACK	WndProc(HWND, UINT, WPARAM, LPARAM);
    LRESULT CALLBACK	About(HWND, UINT, WPARAM, LPARAM);

    Thanks, for the info. I found it. I had several ShowWindow()s in the code. Source is getting too big I guess.

    Sorry for the delayed response. I had a major time headache.
