DLL

I have a simple example on my website:

Good luck!!

And how can I use dll in VB? I need a simple example of using delphi dll in VB.

In a module type something like:

Public Declare Function DelphiFunc Lib "MyDelphiDLL.dll" (ByVal TestInt As Long) As Long

or for a procedure:

Public Declare Sub DelphiProc Lib "MyDelphiDLL.dll" (ByVal TestStr As String)

Your Delphi DLL unit would look something like:


library MyDelphiDLL;

...
....

uses Windows;
...
...

function DelphiFunc(TestInt: integer): integer;
begin
  Result := TestInt * 2;
end;

procedure DelphiProc(TestStr: PChar);
begin
  MessageBox(Application.Handle,TestStr,'DelphiProc', MB_OK or MB_APPMODAL);
end;

...
...

exports DelphiFunc, DelphiProc;
