void CDisplay_Crystal_RPTDlg::OnDisplay()
{
// TODO: Add your control notification handler code here
// by default the ID of the CCrystalCtrl is IDC_CRYSTALREPORT1

UpdateData(TRUE);
// by default the ID of the CCrystalCtrl is IDC_CRYSTALREPORT1
CCrystalCtrl *m_cryscontrol =
( CCrystalCtrl*)( GetDlgItem(IDC_CRYSTALREPORT1));
CString str;
str = "{Table1.ID} = 1";
// where Table1 and Name is a name and a field
//in your Database, m_StudentName is a member variable of an edit box.

m_cryscontrol->SetReportFileName("C:\\Documents and Settings\\Owner\\My Documents\\Bryan\\C++code\\Display_Crystal_RPT\\Re port1.rpt");
