CString strFileName; TCHAR FileName[MAX_PATH]; TCHAR bigBuff[2048] = _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); 站.长站

// Modify OPENFILENAME members directly to point to bigBuff dlg.m_ofn.lpstrFile = bigBuff; dlg.m_ofn.nMaxFile = sizeof(bigBuff); @com

if(IDOK == dlg.DoModal() ) { strFileName = dlg.GetPathName(); lstrcpy(FileName,strFileName); OpenSchemaX(FileName); }（出处：风闪网路学院）中国站.长.站
