<호출>

CString comStr;

comStr=((CMdbdemoApp*)AfxGetApp())->m_comString;

m_hCom=MDB_OpenComPort(comStr.GetBuffer(comStr.GetLength()),100,m_hWnd);



변수 내용m_comString="COM1"





var

Form1: TForm1;

m_hCo:LongWord;

m_Hwnd:LongWord;



implementation



function MDB_OpenComPort(c:PChar;polltime:integer; hWnd:LongWord):LongWord; stdcall;external 'mdbdll.dll';

{$R *.DFM}



procedure TForm1.Button1Click(Sender: TObject);

begin

m_hCo:=MDB_OpenComPort('COM1',100, m_hWnd);

end;



호출을 하면 손실된 엑스포드 MDB.DLL .... 하고 메시지가 나오네요

도무지 모르겠네요

고수님들의 방법을 알려주십시요 꼭 이요
