调用方法

CString strFileName;
TCHAR FileName[MAX_PATH];
TCHAR bigBuff[] = _T(); // maximum common dialog buffer size
TCHAR szFilter[] = _T(Text Files (*mdb)|*mdb|All Files (**)|**
);
CFileDialog dlg(TRUE NULL NULL
OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT szFilter);

// Modify OPENFILENAME members directly to point to bigBuff
dlgm_ofnlpstrFile = bigBuff;
dlgm_ofnnMaxFile = sizeof(bigBuff);

if(IDOK == dlgDoModal() )
{
strFileName = dlgGetPathName();
lstrcpy(FileNamestrFileName);
OpenSchemaX(FileName);
