Formatting message from .NET MSMQ message so VB6 MSMQ objects can read

I am attempting to package data in a VB.NET application and send it to a message queue.  The application reading that message queue is written in VB6.  The VB6 application is unable to properly read the message body.

I have tried using all the different formatters available but they do not seem to make a difference (other than when using the XML formatter i can read the xml, but i don't want to have to do that).

Specifically I want to packaga a byte array in VB.net and unpackage it in VB6.  All using MSMQ v3.

I believe you have to use the ActiveX formatter in your dotnet application. This will allow the serialization to use the formatting supported by COM. The XML/SOap formatters are not supported natively in VB6, IIRC.

The other alternative is to just use the XML formater, and then use the XML parser on the VB6 size to parse the message. You lose the ability to automatically deserialize a message, but I don't think that's that big of a deal. Basically just read the xml, then load it as an XML document (.LoadXML  method) into an XML Document object and then use XPath queries...

I eventually got to the point where I simply wrote to the BodyStream property of the Message and sent it that way - it worked ok so I just ignored the Formatter property.  I would still like to be able to figure out how to send packets natively (for instance using the ActiveX formatter).  I was unable to get the ActiveX formatter to generate anything that was readable by the VB6 client.
