SUMMARY
When you use SMTP as a Primary Transport, the default subject line that is sent with the message contains the interchange GUID. You can manually modify the subject line by opening the Channel that is bound to the port and overriding the properties by clicking the Advanced button at the end of the Channel Wizard. This article describes how to programmatically change the subject line for a port that is using SMTP as its Primary Transport.



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(&quot;BizTalk.BizTalkConfig.1&quot;) Set objDic = CreateObject(&quot;Commerce.Dictionary&quot;)

' 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 (&quot;XMLFromSource&quot;) objPort.LoadByName (&quot;XMLToFlat&quot;) 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 = &quot;this is a test&quot; 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.
