谁能帮我看看我的代码哪错了。。。


            TCHAR szFilePath_Name[MAX_PATH][256];//存放多个文件的全路径（路径+文件名）
            int pianyi = 0;//打开歌曲时记录歌曲的编号，为了多次打开时编号能连续，所以设为全局变量
            int xuhao = 0;//为列表中的歌曲添加序号

            OPENFILENAME ofn;
            TCHAR szFile[256*MAX_PATH];//文件全路径
            TCHAR szPath[256];//文件纯路径
            char * p;//指向歌曲的名字
            int zk = 0;

            ofn.lpstrFile = szFile;
            ofn.lpstrFile[0] = TEXT('\0');
            ofn.nMaxFile = sizeof(szFile)/sizeof(TCHAR);
            //以上为真正有用的代码(定义打开文件窗口)
            //以下代码为了丰富窗口模块和限定打开文件
            ofn.lpstrTitle = NULL;
