How to Programmatically Change the Subject for SMTP Transport (283234)

MORE INFORMATION

The following code snippet is a Visual Basic Script example that demonstrates how to change the subject line for an SMTP Primary Transport.

Save the follow segment of code to a file named SMTPSubjectChange.vbs:

NOTE: The lines of code that are in uppercase need to be changed to point to a valid channel and port in your environment.

Const BIZTALK_CONFIGDATA_TYPE_PRIMARYTRANSPORT = 0
Const BIZTALK_TRANSPORT_TYPE_SMTP = 8

Dim objConfig             '  BizTalkConfig Interface
Dim objChannel            '  BizTalkChannel Interface
Dim objPort               '  BizTalkPort Interface
Dim objDic                '  CDictionary Interface

' Create the two objects that are needed to change the transport

Set objConfig = CreateObject("BizTalk.BizTalkConfig.1")
Set objDic = CreateObject("Commerce.Dictionary")

' Call the Create methods that return the channel and port objects.
Set objChannel = objConfig.CreateChannel
Set objPort = objConfig.CreatePort

' Load the channel and port that utilize the SMTP transport and retrieve the handle to the port
objChannel.LoadByName ("XMLFromSource")
objPort.LoadByName ("XMLToFlat")
portID = objPort.Handle


' Call GetConfigData passing the port handle, which will result in a Dictionary object being returned.
Set objDic = objChannel.GetConfigData(BIZTALK_CONFIGDATA_TYPE_PRIMARYTRANSPORT, portID, BIZTALK_TRANSPORT_TYPE_SMTP)

' Once the dictionary object is returned, we can change the subject and save the data back to the port.
objDic.subject = "this is a test"
Call objChannel.SetConfigData(BIZTALK_CONFIGDATA_TYPE_PRIMARYTRANSPORT, portID, objDic)
objChannel.Save

Set objConfig = Nothing
Set objChannel = Nothing
Set objPort = Nothing
Set objDic = Nothing
				

When the sample has been executed, open the channel and view the Subject property in the Advanced properties.

To manually view the Subject property, perform the following steps:

1. Open the BizTalk Messaging Manager.
2. Click Channels, and then click Search Now.
3. Double-click the channel in question.
4. Click Next five times, click Advanced, and then click Properties.
