delphi WideString is actually OLE-String.
I just changed to PAnsiChar

If not, you'll only get unmanaged assemblies,
which you'd need to create a wrapper for,
or use the Source Forge version to enable Delphi 5+ for .Net usage:

hi i built a very simple dll with delphi
library Printing;
uses
SysUtils, Classes, Dialogs;
{$R *.res}
function Hello: WideString; stdcall;
begin
ShowMessage('test');
result := 'blah';
end;
exports Hello;
begin end.
In VB.Net, i tired calling it. the ShowMessage executes, so that's a
start. I get this error afterwards, SEHException - "External component
has thrown an exception."
this is how i declared it
Declare Function Hello Lib "Printing.dll" () As String
It fails on returning a string. Does anyone know why?
.
