Cannot pass XML doc using Callback

[jhermer]

Hi all,

I have an ActiveX exe running as my server and a standard exe as my client. I have setup a standard callback between the two (copied from the Coffee2 example in msdn).

My callback is defined as follows in an ActiveX dll (the interface definition)

Public Sub StationSoftwareEvent(ByVal stationMsg As FreeThreadedDOMDocument)
End Sub

In my client (which is receiving this document) I append the document to a local copy using the following code:

mtmpDOC.childNodes(0).appendChild stationMsg.childNodes(0).childNodes(0)

Where mtmpDOC is also created as a FreeThreadedDOMDocument

I however get the following error message when the above line tries to execute:

Run-time error '-2147024809 (80070057)':
the parameter is incorrect.

I am using MSXML v3 sp1 with ADO 2.6 (the xml component didn't seem to work without it installed).


I have sucessfuly done the above when I include all the code in one project and do not use callbacks or events. So what am I missing when I use callbacks?

Any help would be appreciated.

Regards,
Jarrod
