[RESOLVED] Locate Object reference not set?

HI,

I keep getting this error -

_{"Object reference not set to an instance of an object"}

Does anyone know how to trap the exact error location, or at least get a more informative error message?

Here is an example of my code where the error seems to be happening but everything looks okay to me

VB Code:

Private Sub cmdSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSubmit.Click
        Dim sMsg As String = ""
        Try
            If LCase(txtEdit.Text) = "true" Then
                Response.Redirect("complete.aspx?display=pro_edit")
            End If
 
        Catch ex As Exception
            ' Record any exceptions and exit
            sMsg = "The following exception occurred: Submit<br />" + ex.Message.ToString
        End Try
 
        If sMsg <> "" Then
            Message.Visible = True
            Message.Text = sMsg.ToString
        End If
    End Sub

Cheers Al

1) Just set a breakpoint in your code where ever the error is occurring.

2) Don't use LCase, use txtEdit.Text.ToLower

3) and change this

VB Code:

If sMsg <> "" Then
 
[color=red]To this[/color]
 
If sMsg.Length > 0 Then

Memnoch1207,

Thanks for that and thanks for the tips

If I want to lowercase and trim can I call as follows -

VB Code:

sUsername = Username.Text.Trim.ToLower

Does this work with the querystring? I'm getting yet another object ref error

VB Code:

If Request.QueryString("edit").ToLower = "true" And iUserID > 0 Then

Cheers Al
