vb调用delphi dll

我用DEPHI7.0编写了一个DLL,在DELPHI里可以调用,但我不知道怎么在VB里调用,有高手懂请一定赐教,感恩不尽!
     下面是DLL模块里的部分代码:
     library prjDLL;
     
     uses
     SysUtils,
     Forms,
     Windows,
     Messages,
     Classes,
     DLLFormUnit in 'DLLFormUnit.pas' {frmDLLForm},
     AboutUnit in 'AboutUnit.pas' {frmAbout},
     sumt_fgh in 'sumt_fgh.pas' {Form3};
     
     {$R *.res}
     
     var
     DLLApp: TApplication;
     DLLScr: TScreen;
     function CreateDLLForm(App: TApplication; Scr: TScreen):TForm;
     
     
     var
     ptr:PLongInt;
     begin
     Application := App;
     Screen := Scr;
     Application.CreateForm(TfrmDLLForm, frmDLLForm);
     Application.CreateForm(TfrmAbout, frmAbout);
     Application.CreateForm(TForm3, Form3);
     result:=frmDLLForm;
     end;
     
     procedure ExitDLL(Reason: Integer);
     begin
     if Reason = DLL_PROCESS_DETACH then
     begin
     Application := DLLApp;
     Screen := DLLScr;
     end;
     end;
     
     exports
     CreateDLLForm;
     
     begin
     DLLApp := Application;
     DLLScr := Screen;
     DLLProc := @ExitDLL;
     
     end.
