Some years ago I made an app with a RemoteDataModule in Delphi 6. I added
some methods to the automatically generated typelib. All this worked fine.
I moved to Delphi 2006, and all the old stuff compiled and runned without
problems.
Now I am creating a new, similar app in Delphi 2006, but I run into some
problems:
1. In the old app I used functions which returned Integers (idl type: long)
and booleans (idl type: variant_bool). The new D2006 typelibrary editor
doesn't allow this, and says: "Functions of Automation Interfaces must have
a return type of HRESULT"
2. In the old app I used an method with a in/out parameter of type
WideString (idl type: BSTR). The new D2006 typelibrary editor doesn't allow
this, and says: "Out parameer requires pointer type". Then I try this with a
PChar (idl type: LPSTR), which AFAIK is a pointer type, but I still get the
same error-message.
Can anyone tell me how to do what I want in Delphi 2006 (or 2007)
