[2005] Try/Catch Code correctness, advice(seeking).

[smilbuta]

Hello community.

I am handling a nothing value for a set of variables and i want to know what is the best way to do this code wise. This is not an error question but more of how i can improve consiceness of the code.

App info: the combo boxes (usename and status) are databound to tables in sql database. Im dealing with an error if a user trys to type in the feild and submit. since the user enterd data has a selected value of Nothing according to VS , i can throw an error informing the user of his stup.. AHEM!.. issue.

Currently my code looks like the following.

        Try
            If cboUserName.SelectedValue Is Nothing Then
                MessageBox.Show("woops, invalid name")
            Else
                userIdValG = CStr(cboUserName.SelectedValue)
            End If

            If cboStatus.SelectedValue Is Nothing Then
                MessageBox.Show("woops, invalid status.")
            Else
                statusIdValG = CStr(cboStatus.SelectedValue)
            End If

        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

The core of my question deals with my IF statments and is ther a more efficient way to make that code more consice. In the actual app i have 7 combo boxes and the over all code would be slightly long and seemingly bloated... any advice welcome.. Thanx!!!
