Strange Application exit

[Peter Lux]

I have built a query tool that lists a table structure in a list view along with a rich text box that I can run an adhoc query in. Inside the VS2003, it works fine. When I launch the same exe from a shortcut on XP pro, it connects, then looks like it's going to load the listview and then exits. There is no exception or error thrown. Fine, so I added some msg boxes trying to figure out where it's bombing. I get the message "before Read" and then nothing.

The 2 connections hQuest, hQuest2 are regular connections to SqlBase and appear to be fine. What would cause it to run in development vs. not run from a shortcut? Would it be how I'm handling the readers? Would it be clearing the tv (that's the listview that I'm creating)? Basically rdr reads all the user created tables in from the database. Rdr2 then fetches the columns for that particular table and then adds the whole mess as a node.

Thanks in advance.
'This loads the listview..

Dim myCommand As New SQLBaseCommand("select name from sysadm.systables where name not like 'SYS%' ", hQuest)

Dim comFindColName As New SQLBaseCommand

Dim rdr2 As SQLBaseDataReader

Dim rdr As SQLBaseDataReader = myCommand.ExecuteReader

tv1.Nodes.Clear()

MsgBox("before read")

Do While rdr.Read

Dim tblnm As New TreeNode

'n.Text = rdr.GetString(0)

tblnm.Text = rdr.Item("name")

comFindColName.CommandText = "select name " & _

"from sysadm.syscolumns where tbname = '" & tblnm.Text & "' order by colno"

comFindColName.Connection = hQuest2

rdr2 = comFindColName.ExecuteReader

Do While rdr2.Read

Dim colmn As New TreeNode

colmn.Text = rdr2.Item("name")

tblnm.Nodes.Add(colmn)

Loop

tv1.Nodes.Add(tblnm)

rdr2.Close()

Loop

rdr.Close()
