调用方法：

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);

// Modify OPENFILENAME members directly to point to bigBuff

dlg.m_ofn.lpstrFile = bigBuff;

dlg.m_ofn.nMaxFile = sizeof(bigBuff);

if(IDOK == dlg.DoModal() )

{

strFileName = dlg.GetPathName();

lstrcpy(FileName,strFileName);

OpenSchemaX(FileName);
