不知道什么地方错了

Answer 1

WndClass.lpszClassName="wintext";hWnd=CreateWindow(
"文本",  
"文本显示实例",  
-->hWnd = CreateWindow("wintext", ...);

Answer 2

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow )
{  
MSG Message;
if(!InitWindowsClass(hInstance))
return FALSE;
if(!InitWindows(hInstance,nCmdShow))
return FALSE;
while(GetMessage(&Message,0,0,0))
{  
TranslateMessage(&Message);  
DispatchMessage(&Message);  
}  return Message.wParam;  
}  把这一个整个提到外面来

Answer 3

把switch(iMessage)那段放到
int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow )这一段后面
