3 things which look odd are: - the stdcall calling convention - the delphi string parameter - C knows nothing of delphi's reference counted strings, and by looking at Andre's declaration, it looks very likely that Henrick's declaration is wrong. - procedure declaration rather than function (thus being unable to check the return value if it failed on that call) (and "far" is a no-op in 32 bit delphi, but not an error) HTH R.
