程序怎么无法显示

Question

有菜单呀，这里是源程序
test01.h
HINSTANCE hInst;//这是示范程序test01的头文件test01.h
//函数原型
//过程
LRESULT CALLBACK MainWndProc(HWND,UINT,WPARAM,LPARAM);//函数
BOOL InitApplication(HINSTANCE);
BOOL InitInstance(HINSTANCE,int);
VOID InitAlignMenu(HWND);test01.cpp

Answer 1

运行之前，先加上一句，AFxmessagebox("ok");
如果　对话框能显示出来，说明程序没问题
它只是在DOS上运行，去DOS下执行吧

Answer 2

少打了一个空格：
wcSimpwin.lpszClassName="Simpwin WClass";      //这儿有空格
hWnd=CreateWindow(
        "SimpwinWClass",    //这儿没有空格。
        ...
注册的类名要和创建窗口用的类名一致。
