帮忙看看，窗口怎么出不来

Question

debug编译能通过，就是打开执行文件后，什么也没发生，窗口也没有
不过release版能正常运行出来编译器使用vc8.0，设置上就是把默认的unicode改成了多字节字符支持主要代码如下
事件处理函数只是负责一些基本的消息处理，所以就不列出来了

Answer 1

那还问什么啊？？可以用就行了，发行版本也就是用release了

Answer 2

debug应该没问题啊
不过重新建了项目，一样的代码，设置，release版也无法运行了

Answer 3

if (PeekMessage(&msg,NULL,0,0,PM_REMOVE))
------------------------------------------------
应该是 if(GetMessage(&msg,NULL,0,0))

Answer 4

PeekMessage() 是为了构建无等待的事件循环
没什么关系

Answer 5

老兄,你把代码贴全了看看,贴出个能编译的,也没有WinProc,那个Windowed也不知道做什么用的,怎么给你看啊

Answer 6

和回调函数大概也没什么关系#define WINDOWED true  //标识是否为窗口程序LRESULT CALLBACK WndProc(HWND hwnd,                    UINT msg, 
                         WPARAM wparam,
      LPARAM lparam)
{

    PAINTSTRUCT ps;    // used in WM_PAINT
  
    switch(msg)
{
case WM_CREATE: 
        {
// do initialization stuff here
return(0);
} break;    case WM_PAINT:
         {

         BeginPaint(hwnd,&ps);         // end painting
         EndPaint(hwnd,&ps);
         return(0);
        } break; case WM_DESTROY: 
{
// kill the application
PostQuitMessage(0);
return(0);
} break; default:break;    } // end switchreturn (DefWindowProc(hwnd, msg, wparam, lparam));} // end WinProc

Answer 7

在初始化winclass时加上一条
winclass.hIconSm = NULL;
不然的话这里不定是什么值,系统在加载小图标时就出问题了
