Problem with Streams - Converting VB Code to C#

deV.ch

Hi Everybody,

I'am trying to convert an old vb asp script to convert to asp.net

Now here is the old asp code:

        Set ComCom = Server.CreateObject("NSComCom2.CommunicationComponent")
	Set SBA = Server.CreateObject("SocketBusAdapter.SocketBusAdapter")
	SBA.ReceivingTimeout = 200000

	Set InMsg = Server.CreateObject("MSMQBusAdapter.InMessage")
	Set OutMsg = Server.CreateObject("MSMQBusAdapter.OutMessage")

	ComCom.AddBusAdapter SBA,0
	Set OutMsg = ComCom.CreateoutMessage("Sockets://" & ServKonf.getActNASHostAndPort)

	sendDOM.Save OutMsg.GetStream()

	Set InMsg = OutMsg.SendWaitForReply(0)
        
        RespDOM.async = False
	RespDOM.Load(InMsg.GetStream())
  	InMsg.CommitMessage

I had a lot problems with the Type of Streams, when i tried to write that code in C#. Can anyone convert that code to c# for me?
How can i us de XMLDocument.Load() Method with the Stream from the InMsg and OutMsg?

OK i got it know to work... in a strange way:
Only if i pass simple requests i get an answer, if i pass a big XML Request, than it loses connection to the InMsg Stream and i get this error:
(Ausnahme von HRESULT: 0x80030102 (STG_E_REVERTED))

That happens when the COMXMLDocument tries to read from the InMsg Stream

Here is the Code:

COMXMLDocument COMResponse = new COMXMLDocument();      
      try {

        NSCOMCOM2Lib.CommunicationComponentClass ComCom = new CommunicationComponentClass();
        SOCKETBUSADAPTERLib.SocketBusAdapterClass SBA = new SOCKETBUSADAPTERLib.SocketBusAdapterClass();
        SBA.ReceivingTimeout = 200000;

        ComCom.AddBusAdapter(SBA, 0);
        OutMsg = ComCom.CreateoutMessage("Sockets://" + ServKonf.getActNASHostAndPort()) as NSCOMCOM2Lib.IOutMessage;
                
        COMXMLDocument COMXmlDoc = new COMXMLDocument();
        COMXmlDoc.LoadXml(sendDOM.InnerXml);
        COMXmlDoc.Save(OutMsg.GetStream() as System.Runtime.InteropServices.UCOMIStream);

        InMsg = OutMsg.SendWaitForReply(10000) as NSCOMCOM2Lib.IInMessage;
        if (InMsg != null)
            COMResponse.Load(InMsg.GetStream() as System.Runtime.InteropServices.UCOMIStream);        
        respDOM.LoadXml(COMResponse.InnerXml);
        InMsg.CommitMessage();
      }

Whats the problem here? Why do small requests work and big ones don't? The old asp Script works just fine...
