        Call conecDB()
        Call disControl()
        'Validation
        Try
            If invalidSaveEntry() = True Then
                Call enaControl() 'enable text field
                Exit Sub
            End If
            'Start Save

            SQL = "Insert into tblstud_accdata(accdate,lastname,firstname,middlename,age) values(@date,@lname,@fname,@mname,@age)"
            ' Add Parameters to Command Parameters collection
            comDB.Parameters.Add("@date", SqlDbType.Date).Value = accdate
            comDB.Parameters.Add("@lname", SqlDbType.VarChar, 50).Value = txtLname.Text
            comDB.Parameters.Add("@fname", SqlDbType.VarChar, 50).Value = txtFname.Text
            comDB.Parameters.Add("@mname", SqlDbType.VarChar, 50).Value = txtMname.Text
            comDB.Parameters.Add("@age", SqlDbType.Int).Value = txtAge.Text()
            comDB.Prepare() 
            Call execComDB(SQL)    

            MsgBox("Record(s) saved...", MsgBoxStyle.Information, "Record(s) saved...")
            If MsgBox("Do you want to add new record(s) ?", MsgBoxStyle.Question + MsgBoxStyle.YesNo, "Confirmation...") = MsgBoxResult.Yes Then
                Call cleartxt()
                Call enaControl()

            Else
                Me.Close()    'Close the form
                ' Display new record
                SQL = "Select * from tblstud_accdata " & "order by accno desc"
                Call dispRec(SQL)
                Call frmSearch.dispRecCount() 'Display record count
                '--- End of displaying new record

            End If


        Catch ex As Exception
            MsgBox(ex.Message)

Date variable is a keyword so try giving some other name in ur database

He's right, in naming you database fields try to include tablename_[fieldname]. I encountered that issue before and that was the word PASSWORD, I did'nt know it is a reserved word.
