Hi Lasse,
the line that seems it causes the problem:
mqQMgr = New MQQueueManager(mManagerName, channelName, connectionName)
yes, i know it is not C# problem althouhg i use bv and C# together.
Thank you

Hi,
Currently I have been working on a project sending a file with
certfication and signature (the application is running on Windows
2003
Server Standard Edition) to IBM MQ server via IBM Websphere MQ
windows
client v6.0.
And I get the followoing error message when I debug my application :
"An unhandled exception of type 'System.NullReferenceException'
occurred in Unknown Module.
Additional information: Object reference not set to an instance of an
object."
When I do connect to MQ server on DOS by using put messages and get
messages, no problem with connections.
IS this a known bug ? IS there any fix patch or refresh patch?
IS this may be a memory problem?
I cannot clearly debug my application.
Any help will be appriciated.
Some of my code that may give a light:
Dim fs As FileStream
Dim sr As StreamReader
Dim sw As StreamWriter
Dim hexString As String = ""
Dim sb As StringBuilder
Dim i As Integer
Dim xmlBuffer As String
Dim key As String
