[dba-VB] VB.net 2005 data sources screwy

John,
	If I understand your problem correctly you need to open multiple
data sources at the same time.  We got around this by creating separate
functions to open individual data sources.  Their may be a better way but
this has worked well for us.

 Dim cn As SqlConnection
	Dim cmd As SqlCommand
	Dim dr As SqlDataReader
	Dim cn2 As SqlConnection
	Dim cmd2 As SqlCommand
	Dim dr2 As SqlDataReader


	Dim cnmass As SqlConnection
	Dim cmdmass As SqlCommand
	Dim drmass As SqlDataReader

Sub OpenConnection(strDB as String)
		If cn Is Nothing Then
			cn = New SqlConnection( "server=" & SQL_SERVER &
";uid=" & DB_User & ";password=" & DB_Password & ";database=" & strDB )
			cn.Open()
		End If

		If Not dr Is Nothing Then
			If Not dr.IsClosed() Then dr.Close()
		End If
	End Sub

	Sub SQL_Select(strDB as String, SQL as String)
		OpenConnection(strDB)
							
		cmd = New SqlCommand( SQL, cn )
		cmd.CommandTimeout = 300
		dr = cmd.ExecuteReader()	
	End Sub

	Sub OpenConnection2(strDB as String)
		If cn2 Is Nothing Then
			cn2 = New SqlConnection( "server=" & SQL_SERVER &
";uid=" & DB_User & ";password=" & DB_Password & ";database=" & strDB )
			cn2.Open()
		End If

		If Not dr2 Is Nothing Then
			If Not dr2.IsClosed() Then dr2.Close()
		End If
	End Sub

	Sub SQL_Select2(strDB as String, SQL as String)
		OpenConnection2(strDB)
							
		cmd2 = New SqlCommand( SQL, cn2 )
		cmd2.CommandTimeout = 180
		dr2 = cmd2.ExecuteReader()	
	End Sub

	Sub SQL_NonSelect(strDB as String, SQL as String)
		OpenConnection(strDB)
		
		cmd = New SqlCommand( SQL, cn )
		cmd.ExecuteNonQuery()
	End Sub

	Sub SQL_NonSelect2(strDB as String, SQL as String)
		OpenConnection2(strDB)
		
		cmd2 = New SqlCommand( SQL, cn2 )
		cmd2.ExecuteNonQuery()
	End Sub

Sub CloseConnection()
		If Not dr Is Nothing Then
			If Not dr.IsClosed() Then dr.Close()
		End If

		cn.Close()
		cn = Nothing	
	End Sub

	Sub CloseConnection2()
		If Not dr2 Is Nothing Then
			If Not dr2.IsClosed() Then dr2.Close()
		End If

		cn2.Close()
		cn2 = Nothing	
	End Sub
	
Hope this helps you.

I have used the Data Sources wizard to build data sources, but they don't
display in the data sources window.  If I build another, it tells me that
the previous one exists, and if I do build another, it is not displayed
either.

Also, if I drop a data adapter into a form it does so, but immediately says
that the data source doesn't exist.  Has anyone seen / worked around
behavior like this?
