Question

Microsoft Visual C++里制作一个Windows窗口的代码是什么？

我是初学者，现在只会用MessageBox，要做一个Windows的窗口要怎么写呢？

Answer 1

把以下文件编译就可以了，直接用VC打开，然后编译、运行，Ok
#include <windows.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,PSTR szCmdLine,int iCmdShow)
{
static TCHAR szAppNume[]=TEXT("HelloWin");
HWND hWnd;
MSG msg;
WNDCLASS wndclass;

wndclass.style = CS_HREDRAW|CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);
wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppNume;
if(!RegisterClass(&wndclass))
{
MessageBox(NULL,TEXT("This program requires Windows NT!"),szAppNume,MB_ICONERROR);

return 0;
}

hWnd = CreateWindow(szAppNume, //window class name
TEXT("The Hello Program"), //window caption
WS_OVERLAPPEDWINDOW, //window style
CW_USEDEFAULT, //initial x postion
CW_USEDEFAULT, //initial y postion
CW_USEDEFAULT, //initial x size
CW_USEDEFAULT, //initial y size
NULL, //parent window handle
NULL, //window menu handle
hInstance, //program instance handle
NULL); //creation parameters
ShowWindow(hWnd,iCmdShow);
UpdateWindow(hWnd);

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

return msg.wParam;
}

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

switch(message)
{
case WM_CREATE:
break;
case WM_PAINT:
hdc = BeginPaint(hWnd,&ps);
GetClientRect(hWnd,&rect);

DrawText(hdc,TEXT("Hello,Windows 2000!"),-1,&rect,
DT_SINGLELINE|DT_CENTER|DT_VCENTER);
EndPaint(hWnd,&ps);
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hWnd,message,wParam,lParam);
}

#include<afxwin.h>
我用MFC写的一个小例子,希望对你有帮助
class CMyFrameWnd:public CFrameWnd
{
private:
CStatic* m_pStatic;
CButton* m_pButton;
protected:
DECLARE_MESSAGE_MAP()
public:

CMyFrameWnd()
{
Create(NULL,"我的窗口");
m_pStatic = new CStatic();
m_pButton = new CButton();
m_pStatic->Create("我是一个标签",WS_CHILD|WS_VISIBLE|SS_CENTER|SS_GRAYRECT,CRect(200,200,100,100),this,1000);
m_pButton->Create("我是一个按钮",WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,CRect(0,0,100,30),this,2000);
this->SendMessage(WM_COMMAND,2000,0);
}
~CMyFrameWnd()
{
delete m_pStatic;
delete m_pButton;
}
afx_msg void OnPaint();
afx_msg void OnClick();

};

class CMyApp:public CWinApp
{
public:

BOOL InitInstance();
};
BOOL CMyApp::InitInstance()
{
m_pMainWnd = new CMyFrameWnd();
m_pMainWnd->ShowWindow(3);
m_pMainWnd->UpdateWindow();
return TRUE;

};
void CMyFrameWnd::OnPaint()
{
CPaintDC dc(this);
CRect rect;
this->GetClientRect(&rect);
CBrush brush;
brush.CreateSolidBrush(RGB(0,255,0));
dc.FillRect(rect,&brush);
dc.SetTextColor(RGB(255,0,0));
// dc.SetBkColor(RGB(0,0,200));
dc.TextOut(rect.Width()/2,rect.Height()/2,"MFC应用程序");

}
void CMyFrameWnd::OnClick()
{
MessageBox("你单击了我!");
::SetWindowText(m_hWnd,"改变窗口");

}
BEGIN_MESSAGE_MAP(CMyFrameWnd,CFrameWnd)
ON_WM_PAINT()
ON_COMMAND(2000,CMyFrameWnd::OnClick)
END_MESSAGE_MAP()
CMyApp theapp;

这个东西说来复杂了，一般的作法是：继承一个WNDCLASS类，创建一个新的类，然后重载一个初始化的虚拟函数，对窗口的参数进行初始化。然后注册这个类，再调用它，然后把窗口显示出来并进行相应的消息响应。

这个东西不是一两句话说得清的，我现在也在学习这个软件，你对这个有兴趣的话，发信息给我，加我QQ。

用MFC，file->new->projects->MFC AppWizard(exe)，点击下一步进行配置就可以生成了，根据你自己的需要可以生成单文档、多文档或者基于对话框的

建议你看MFC编程实例这本书,
要先注册一个窗口类AfxRegisterWndClass.然后就可以创建窗口了,用CreateWindow函数.
你也可以用VC App Wizard 来生成一个框架,然后自己看是怎么做的
