V8i MDL application debugging help

Hi, 

I am trying to debug MDL application for the first time and I am using VS 2005 for that. 

Microstation is first manually opened and then the VS 2005 to set breakpoints. There's a info icon on break-point that says "The breakpoint will not currently be hit. No symbols have been loaded for this document". As it says, I don't see my MDL app hitting debug model in VS. How do I solve this ?

I attached the project to the process ustation.exe. Also, my application has a PDB file that's generated during the build process. I read that the symbols are generated in these PDB files and if these symbols are not loaded we have to manually load them. I am not sure how to load them and need some help.

Thanks,
