问题描述

LRESULT CALLBACK WindProc(HWND, UINT, WPARAM, LPARAM);
	//prototype

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
	TCHAR		szAppName[] = _T("my window");

	wndclass.hIcon			=	LoadIcon(NULL, IDI_APPLICATION);
	wndclass.hCursor		=	LoadCursor(NULL, IDC_CROSS);

		CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
		NULL, NULL, hInstance, NULL);

	ShowWindow(hWnd, iCmdShow);
	UpdateWindow(hWnd);

	while (GetMessage(&msg, NULL, 0, 0))
	{
		TranslateMessage(&msg);
		DispatchMessage(&msg);
	}
	return msg.wParam;
}

LRESULT CALLBACK WindProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	HDC				hdc;
	PAINTSTRUCT		ps;
	RECT			rect;

	switch (message)
	{		
	case WM_PAINT:
		hdc = BeginPaint(hWnd, &ps);
		GetClientRect(hWnd, &rect);			
		DrawText(hdc, _T("hello window"), -1, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);			
		EndPaint(hWnd, &ps);
		break;

	case WM_DESTROY:

	}

	return DefWindowProc(hWnd, message, wParam, lParam);
}

它没有最小化，关闭和最大化按钮。我想知道为什么会这样？我应该做些什么改变来获得这些按钮？

提前谢谢

That's the code I've tried..

It hasnt minimize, close and maximize buttons. I want to know why this happens ? And what changes should I make to get those buttons ?

推荐答案

hWnd = CreateWindow（szAppName，

_T（我的窗口），

WS_OVERLAPPEDWINDOW，

CW_USEDEFAULT，CW_USEDEFAULT，CW_USEDEFAULT，CW_USEDEFAULT，

NULL，NULL，hInstance ，NULL）;



第三个参数应该是WS_OVERLAPPEDWINDOW，然后你会看到按钮。

hWnd = CreateWindow(szAppName,
_T("my window"),
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL);

The third parameter should be WS_OVERLAPPEDWINDOW,then you will see the buttons.
