Hi cweber,
I tested with the solution in your first link, it works fine in ProjectWise environment. Please following the below steps to use this solution:
1. Download the attached test.mvba file and save it into your ...\Workspace\standard\vba folder;
2. Start MicroStation, load this test.mvba into VBA Project Manager and tick "Auto-Load" column of Test. Shown as below:
3. Restart your MicroStation, and see what happen for the title of your MicroStation application window.
