    Thanks again! 🙂

    About the custom pipeline component:

    That’s what I did, indeed 😉 But I keep on getting that error… It’s strange though, because I find the same information when I google a bit for the problem. It seems there must be something else wrong with my piece of code? When I step through the code (debug it), it gives no errors. But when I check the eventlog afterwards, I get the “object reference not set to an instance of an object” errors…

    Here’s the piece of code I’m using:

      public Microsoft.BizTalk.Message.Interop.IBaseMessage Execute(Microsoft.BizTalk.Component.Interop.IPipelineContext pc, Microsoft.BizTalk.Message.Interop.IBaseMessage inmsg)
            {
                string messageTypeIncomingMessage = “”;
                object oMessageType = inmsg.Context.Read(“MessageType”, “http://schemas.microsoft.com/BizTalk/2003/system-properties“);
                if (oMessageType != null)
                {
                    messageTypeIncomingMessage = (string)oMessageType;
                    messageTypeIncomingMessage =
                        messageTypeIncomingMessage.Substring(messageTypeIncomingMessage.IndexOf(‘#’) + 1);
                }

                // Make sure the properties aren’t null and the messageType was found
                if (!String.IsNullOrEmpty(messageTypes)
                    && !String.IsNullOrEmpty(messageTypeIncomingMessage))
                {
                    String[] messageTypesArray = messageTypes.Split(new char[] { ‘;’ }, StringSplitOptions.RemoveEmptyEntries);

                    // Loop all elements to check if the message needs to be ignored
                    for (int i = 0; i < messageTypesArray.Length; i++)
                    {
                        string messageTypeFromArray = messageTypesArray[i];
                        if (messageTypeIncomingMessage == messageTypeFromArray)
                        {
                            // messageType was found -> message needs to be ignored
                            return null;
                        }
                    }
                }

                return inmsg;
            }

     

    About the null adapter:

    Thanks a lot for the information about the 64-bit systems! This adapter works like a charm and does exactly what we need it to do! Great! 🙂
