Public Sub DelModAll(ByVal CCode As String, ByVal DelTable As DataTable)
Dim DelPrm As OleDbParameter
Dim DelCom As New OleDbCommand("Delete from tblmodule where
applicationcode=@CUId", ITRCon)
DelCom.CreateParameter()
DelPrm = DelCom.Parameters.Add("@CUId", CCode)
ModAdapter.DeleteCommand = DelCom
Try
ModAdapter.Update(DelTable)
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub

Public Sub DelApp(ByVal CCode As String, ByVal DelTable As DataTable)
Dim DelPrm As OleDbParameter
Dim DelCom As New OleDbCommand("Delete from tblapplication where applicationcode=@CUId", ITRCon)

End Try
End Sub


Private Sub DeleteApp()
Dim DelRow As DataRow
Dim Delmod, Delmods() As DataRow
If Trim(txtAppCode.Text) <> "" Then
DelRow = ApplicationTable.Select("applicationcode='" & Trim(txtAppCode.Text) & "'")(0)
Delmods = ModulesTable.Select("applicationcode='" & Trim(txtAppCode.Text)
& "'")
If Not (DelRow.IsNull("applicationcode")) Then
DelRow.BeginEdit()
DelRow.Delete()
DelRow.EndEdit()
TempSystemObj.DelApp(Trim(txtAppCode.Text), ApplicationTable)
ApplicationTable.AcceptChanges()
For Each Delmod In Delmods
Delmod.BeginEdit()
Delmod.Delete()
Delmod.EndEdit()
Next
TempSystemObj.DelModAll(txtAppCode.Text, ModulesTable)
ModulesTable.AcceptChanges()
LvwModules.Items.Clear()
ClearMod()
lvwApplications.FocusedItem.Remove()
ClearApp()
End If
End If
