[求助]：GetOpenFileName函数问题

flydyt

请问我的这些代码有什么错误，为什么总不显示打开对话框。谢谢
CString FileName;
char szFile[128];
OPENFILENAME ofn;
bool Falg;

ZeroMemory(&ofn,sizeof(OPENFILENAME));
ofn.lStructSize=sizeof(OPENFILENAME);
ofn.lpstrFile=szFile;
ofn.nMaxFile=sizeof(szFile);
ofn.lpstrFilter="Access 数据库\*.MDB";
ofn.lpstrCustomFilter="Access 数据库\*.MDB";
ofn.lpstrTitle="打开数据库";
ofn.Flags=OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;

if (GetOpenFileName(&ofn)==TRUE)
{
FileName=ofn.lpstrFile;
AfxMessageBox("OK!");
}

去看看这片文章：http://www.vckbase.com/vckbase/v ... dvui_01/0801006.htm
   OPENFILENAME ofn;  // older version
   memset(&ofn, 0, sizeof(OPENFILENAME));//加上这句就可以了
   ofn.lStructSize = sizeof(ofn);
   int nResult = ::GetOpenFileName(&ofn);


//ZeroMemory(&ofn,sizeof(OPENFILENAME));
ofn.lStructSize=sizeof(OPENFILENAME);

谢谢。问题解决。但是为什么返回的文件名是空。我的代码
if (nResult==TRUE)
                {
                        FileName=ofn.lpstrFile;
                        AfxMessageBox(FileName);
                }
