Hello

If several different strong named assembly releases are deployed into the GAC (e.g. 

Sybase.powerbuilder.core

     v4.0_17.0.0.0_12345897d75b

     v4.0_19.0.0.0_65789084e76b

)

or in our case OLF.Agtech.Shared  etc..

How can we specify a specific release of the service on lookup?

for example

connecttonewobject('OLF.SmartSoft.Shared.Wrappers.EncryptionWrapper') is a far as we can specify?

We need to guarantee that we can get a specific release functionality when multiple releases might be present in the GAC

In Regedit find the following:

HKEY_CLASSES_ROOT\Msxml2.XMLHTTP

Under that is CurVer which has the default version of Msxml2.XMLHTTP. You should also see Msxml2.XMLHTTP.3.0, Msxml2.XMLHTTP.4.0, and Msxml2.XMLHTTP.6.0.

When you connect from PowerBuilder you can specify the version:

oleHTTP = CREATE OLEObject
li_rc = oleHTTP.ConnectToNewObject("Msxml2.XMLHTTP.6.0")

Or you can go with the default:

oleHTTP = CREATE OLEObject
li_rc = oleHTTP.ConnectToNewObject("Msxml2.XMLHTTP")
