小弟我最近学习DX编程,按照书上教的,写了个窗口程序,把一个图片加到程序里头去,编译的所有错误都解决了,但是,就是无法运行程序...我都快疯了,我仔细看了代码,就是不知道错在那里,希望各位高手,给我指明活路,我给你们跪下了[em10][em10][em10]
以下是代码,希望各位大哥们帮帮我,救救我啊.!!
主程序 MAIN.CPP

#include <windows.h>
#include "Wnd.h"
#include "MyDDraw.h"
#include <ddraw.h>

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
Win w;
CDDraw d;

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine,int nCmdShow)
{   
    HWND hWnd;
    LPDIRECTDRAWSURFACE7 lpSurf;
    hWnd=w.InitWin(WndProc,hInstance,nCmdShow);
    d.InitDDraw(hWnd);
    d.BlitBack(lpSurf);
    d.FLIP();
    w.RunMsg();

LRESULT CALLBACK WndProc(HWND hWnd,UINT nmsg,WPARAM wParam,LPARAM lParam)

最最基本的窗口类　Wnd.h

#include <windows.h>

        wc.lpszMenuName = NULL;
        wc.lpszClassName = app;

        if(!RegisterClass(&wc))
        {
            MessageBox(NULL,"注册失败","Error!",MB_OK);
        }

        hWnd = CreateWindow(app,"练习1",WS_POPUP,0,0,1027,760,NULL,NULL,hInstance,NULL);

        ShowWindow(hWnd,nCmdShow);
        UpdateWindow(hWnd);

        return hWnd;

int Win::RunMsg()

    while(GetMessage(&msg,NULL,0,0))

求求各位大哥们帮帮小弟我了，我都快崩溃了，就是不知道怎么回事，写了Ｎ次，都是这样，程序可以生成，就是没办法顺利运行，一运行就错误终止，我给你们下跪了，求你们帮我....当然不是没放图片在ＤＥＢＵＧ下面的那个错误，所以这个回答，可以省略了...
