Need Help with MsgBox and Link

[Terrance]

I'm working with ASP.NET 2.0 and I'm trying to figure out; how can I prevent
the link that I have in a datagrid from showing up as a visited link? This is
the code I have in the datagrid for the column:

<asp:HyperLinkColumn HeaderText = "Email"
DataTextField = "Email"
DataNavigateUrlFormatString="mailto:{0}"
DataNavigateUrlField="Email" />

I tried using the attribute Item-Style CssClass and assigning it to a class
value in my style sheet but no luck. Any other suggestions?

Also, I was wondering if I could have someone tell me why my alert box keeps
popping up twice when I run the following code:

Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btnSearch.Click
sqlString = <SELECT STRING>

If ckbIssue.Checked = True Then
Dim blnFlag As Boolean = True
-- If (blnFlag = VerifyData()) = False Then Exit Sub
Dim intIssueNum As Integer = CType(txtIssue.Text, Integer)
Dim strIssue As String = " AND a.track = " & intIssueNum
sqlString = sqlString & strIssue
End If
End Sub
The If statement executes correctly but when it highligts the exit Sub it
goes back to the top of the SQL statement and executes the code a 2nd time.
I can 't figure out why it's doing this.

Thank You,
Terrance Copling
