Windows Form in Shared Add-in not reading App.config settings

[Guest]

Good Morning,
I am developing an Outlook Shared Add-in using VB.Net. A Windows form has
been added to the project, but is not reading the values in the app.config
file during testing. The code (Sub Main) is below and displays "Blank
connection string" is the label. It is called by an Outlook command button
click event:

Private Sub btnCTXNotesHistory_Click(ByVal Ctrl As
Microsoft.Office.Core.CommandBarButton, ByRef CancelDefault As Boolean)
Handles btnCTXNotesHistory.Click
Dim frmNotesHistory As New frmCTXNotesHistory
frmNotesHistory.Main()
frmNotesHistory.Show()
End Sub

Sub Main()
Dim sqlconCTXControl As New SqlClient.SqlConnection
sqlconCTXControl.ConnectionString =
ConfigurationSettings.AppSettings("sqlconCTXControl.ConnectionString")
lblErrorMsg.Text = sqlconCTXControl.ConnectionString.ToString
If lblErrorMsg.Text.Length = 0 Then
lblErrorMsg.Text = "Blank connection string"
End If
End Sub

Thanks.

Only EXE's can read app.config files. An addin is a DLL. You must write
your own custom code to read in your own config values from your own xml
file. You could use something like Enterprise Library Configuration class (a
lot of work if you only have one or two settings -
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag2/html/config.asp).

A dll can read app.config files if it is called from an EXE btw but not on
its own.

Sorry.
