hi
How can I create a full screen window?
what must change in this program? or what should I add?:

#undef UNICODE

#define STRICT

#include <windows.h>

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)

{

	switch(msg)

	{

		case WM_CLOSE:

			DestroyWindow(hwnd);

			return 0;

		case WM_DESTROY:

			PostQuitMessage(0);

			return 0;

		default:

			return DefWindowProc(hwnd,msg,wParam,lParam);

	}

}

void register_class(const HINSTANCE& hInstance)

{

	WNDCLASSEX wcx;

	wcx.cbSize        = sizeof(WNDCLASSEX);

	wcx.style         = 0;

	wcx.lpfnWndProc   = WndProc;

	wcx.cbClsExtra    = 0;

	wcx.cbWndExtra    = 0;

	wcx.hInstance     = hInstance;

	wcx.hIcon         = LoadIcon(0,IDI_APPLICATION);

	wcx.hCursor       = LoadCursor(0,IDC_ARROW);

	wcx.hbrBackground = (HBRUSH)(COLOR_WINDOWFRAME);

	wcx.lpszMenuName  = 0;

	wcx.lpszClassName = "classname";

	wcx.hIconSm       = LoadIcon(0,IDI_APPLICATION);

	RegisterClassEx(&wcx);

}

void message_loop()

{

	MSG Msg;

	while(GetMessage(&Msg,0,0,0) > 0)

	{

		TranslateMessage(&Msg);

		DispatchMessage(&Msg);

	}

}

void create_window(const int& nCmdShow)

{

	HWND hwnd = CreateWindowEx

	(

		0                   ,// dwExStyle

		"classname"         ,// lpClassName

		"title"             ,// lpWindowName

		WS_OVERLAPPEDWINDOW ,// dwStyle

		CW_USEDEFAULT       ,// x

		0                   ,// y

		CW_USEDEFAULT       ,// nWidth

		0                   ,// nHeight

		0                   ,// hWndParent

		0                   ,// hMenu

		0                   ,// hInstance

		0                    // lpParam

	);

	ShowWindow(hwnd, nCmdShow);

	UpdateWindow(hwnd);

}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,

	LPSTR lpCmdLine, int nCmdShow)

{

	register_class(hInstance);

	create_window(nCmdShow);

	message_loop();

	return 0;

}

I didn't get to see your full post, but I know you would need to use the SetWindowLong () function after using CreateWindow () or CreateWindowEx (), and you also need to specify a particular value for the show style parameter of ShowWindow (); that's all I can remember off the top of my head. Ask if you need more details.

Thanks
I don't know what's happen to my post! maybe a vBulletin bug.
the code is the simplest windows api program which creates a window.

Ask if you need more details.

what must be the arguments in:

LONG SetWindowLong(HWND hWnd,

    int nIndex,

    LONG dwNewLong

);

[RhetoricalRuvim]

Here's a segment from a program that I have written before:

	invoke SetWindowLong, eax, GWL_STYLE, WS_MAXIMIZE 

	

	invoke ShowWindow, [hwnd], SHOW_FULLSCREEN 

	invoke UpdateWindow, [hwnd] 

I no longer use the invoke syntax, as I have gone to doing things manually, but it's the same idea.

So the hWnd is obviously the handle to the window you just made, the nIndex is GWL_STYLE, and dwNewLong is WS_MAXIMIZE.

Also, instead of passing SW_SHOWDEFAULT, etc., to ShowWindow (), you pass SHOW_FULLSCREEN to it.

[irancplusplus]

thanks.
with this code I get a full screen window:

SetWindowLong(hwnd,GWL_STYLE,WS_MAXIMIZE);

ShowWindow(hwnd, SHOW_FULLSCREEN);

how can I restore the full screen window to it's former style?

[RhetoricalRuvim]

dwStyle is the third parameter if you're using CreateWindow (), or fourth parameter if you're using CreateWindowEx (). You would perform another function call to SetWindowLong (), with the first two parameters the same, but with the third parameter equal to what you used for the dwStyle value, when you first made the window.

Also, you would want to make a call to ShowWindow (), with the second parameter as SW_SHOWDEFAULT, SW_SHOWNORMAL, or whatever you prefer to use.
