空白窗口应用程序不显示？

Question

当我键入此，我没有得到我的计算机上的一个空白窗口显示：

#define WIN32_LEAN_AND_MEAN 

#include<Windows.h> 

bool InitMainWindow(HINSTANCE, int); 
LRESULT CALLBACK MsgProc(HWND, UINT, WPARAM, LPARAM); 
const int WIDTH=800; 
const int HEIGHT=600; 

HWND hwnd=NULL; 

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdline,  int mCmdShow) 
{ 
    if(!InitMainWindow(hInstance,mCmdShow)) 
     return 1; 
    MSG msg={0}; 

    while(WM_QUIT!=msg.message) 
    { 
     if(PeekMessage(&msg,0,0,0,PM_REMOVE)) 

     { 
      TranslateMessage(&msg); 
      DispatchMessage(&msg); 
     } 
    } 
    return static_cast<int>(msg.wParam); 

} 

bool InitMainWindow(HINSTANCE hInstance, int mCmdShow) 
{ 
    WNDCLASSEX wcex; 

    wcex.cbSize=sizeof(wcex); 
    wcex.style=CS_HREDRAW|CS_VREDRAW; 
    wcex.cbClsExtra=0; 
    wcex.cbWndExtra=0; 
    wcex.lpfnWndProc=MsgProc; 
    wcex.hInstance=hInstance; 
    wcex.hIcon=LoadIcon(NULL,IDI_APPLICATION); 
    wcex.hCursor=LoadCursor(NULL,IDC_ARROW); 
    wcex.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH); 
    wcex.lpszClassName = (LPCWSTR)"tutorialClass"; 

    wcex.lpszMenuName=NULL; 
    wcex.hIconSm=LoadIcon(NULL,IDI_WINLOGO); 

    if(!RegisterClassEx(&wcex)) 
     return false; 

    hwnd=CreateWindow((LPCWSTR)"tutorial class", 
      (LPCWSTR)"tutorial window", 
      WS_OVERLAPPED | WS_SYSMENU |WS_CAPTION, 
      GetSystemMetrics(SM_CXSCREEN)/2-WIDTH/2, 
      GetSystemMetrics(SM_CYSCREEN)/2-HEIGHT/2, 
      WIDTH, 
      HEIGHT, 
      (HWND)NULL, 
      NULL, 
      hInstance, 
      (LPVOID*)NULL); 

    if(!hwnd) 
     return false; 

    ShowWindow(hwnd, mCmdShow); 

    return true; 

} 

LRESULT CALLBACK MsgProc(HWND hwnd, UINT msg,WPARAM wParam,LPARAM lParam) 
{ 
    switch(msg) 
    { 
     case WM_DESTROY: 
      PostQuitMessage(0); 
      return 0; 
     case WM_CHAR: 
      switch(wParam) 
      { 
       case VK_ESCAPE: 
        PostQuitMessage(0); 
        return 0; 
      } 
      return 0; 
    } 
    return DefWindowProc(hwnd, msg ,wParam,lParam); 
} 

在的Visual Studio 2010 Express Edition的，我收到以下错误和警告：

有时在我的电脑上编译需要很长时间，因为它很慢。我不明白代码中有什么错误。我刚开始学习，我试着改变参数，顺序，重新输入所有内容，创建一个新项目，但空白窗口似乎没有出现。这是为什么？

我不知道这段代码有什么问题。或者有些图书馆可能缺失？我有Windows 7 64位家庭版，我也安装了DirectX 11 SDK。

Answer 1

您还可以使用LPCTSTR是在安全方面，如：

wcex.lpszClassName = (LPCTSTR)_T("tutorialClass"); 

做同样的事情，同时呼吁CreateWindow()功能也。

另外尝试从Visual Studio中的Build菜单中选择一次重建解决方案。

或者先选择清洁解决方案，然后再生成解决方案以查看这是否解决您的问题。

您可以执行的另一项操作是删除.ncb，.sdf，.opt，.aps文件（如果它们存在于解决方案目录中），然后再次重新构建解决方案并进行检查。

Answer 2

我知道你的课程名称与wcex.lpszClassName = (LPCWSTR)"tutorialClass"不同;和hwnd=CreateWindow((LPCWSTR)“tutorial class”，
