Have you tried the **GetAllVisibleProjectDescriptors** and **ProjectDescriptor** objects?

**GetAllVisibleProjectDescriptors:**
The list of project descriptors under all domains that the current logged in user is allowed to connect to.

**ProjectDescriptor:**
Get a reference from the list returned by TDConnection.GetAllVisibleProjectDescriptors. The ProjectDescriptor.UId property returns the project's Unique ID number.

**ProjectDescriptor** seems to have a Uid property. According to the API Reference - ''Returns the project's Unique ID number.''

If this doesn't work out for you, you could always set up an ODBC connection inside of workflow and query it from qcsiteadmin_db. This would be insecure though as you would have to pass db login info in workflow.

Thanks, Young Steve. Somehow, I was not putting those pieces together even though I did run across the GetAllVisibleProjectDescriptors method.

So, something like the following should work (I haven't tested it, because I found a workaround):

Dim projectID
Set visProjectsList = TDConnection.GetAllVisibleProjectDescriptors
For Each projDescr In visProjectsList
If projDescr.Name = TDConnection.ProjectName Then
projectID = projDescr.UId
Exit For
End If
Next
