Error in Accessing DLL in Development mode

Hi,

I wrote a .NET DLL(at21_sba.dll) which refers to a few other .NET
Assemblies DLL(SBAAPI.dll).

The I followed some instruction from Microsoft to 'register' the DLL
into my registry so it can be called using CreateOject or OleObject
method.

Then I write a PB application to call a function in at21_sba.dll.
The call works fine in EXE if i copied the refered DLL (SBAAPI.dll)
into my local folder.

However it doesnt work in Development environment. I tried all sorts of
things including Path the my local directory to even copy the
SBAAPI.dll to Windows System directory but to no success. ...

Any ideas ?

Thanks
Kwan
