UserInfoGet is an object that replaces retrieveglobals.dll in GP10. Like the following page says. http://www.microsoftdynamicsforums.com/forums/forum_posts.asp?TID=1499

 I realize that this object is only accesible from VBA, but I am developing a winfows form application. I am not using VS tools.

I was migrating a windows form application that used retrieveGlobals9 to get the credentials of the current connected GP user.

I think I am going to have to create a form requesting the username and password . :-(
