Re: Help please: Trouble getting a value back from COM.

I think Jawin has some problems even after the correction.

Here is what I tried:

In the header file:
STDMETHOD(Garbage)(BSTR InputString, int InputInt, BSTR* returnString);

In the cpp file:
STDMETHODIMP CValidateLogin::Garbage(BSTR InputString, int InputInt,BSTR*
returnString)
{
 *returnString = CString(_T("blah")).AllocSysString();
 return 0;
}

In the idl file:
interface IValidateLogin : IDispatch{
 [id(1), helpstring("method ValidateLogin")] HRESULT ValidateLogin
(BSTR UserName, BSTR Password, BSTR Domain, BSTR Server, BSTR* GroupRet);
 [id(2), helpstring("method Garbage")] HRESULT Garbage([in]BSTR
InputString, [in]int InputInt, [out]BSTR* returnString);


I then called it like this:
  GUID loginGUID = new GUID("{CAAB21D7-C41D-45F9-A610-9ADCAF448161}");
  IValidateLogin iLogin = new IValidateLogin(loginGUID);
  String[] retArray = new String[20];
  iLogin.Garbage("InputString", 5, retArray);

On the last line, it gives me a Type Mismatch error upon execution
(everything compiles of course):
org.jawin.COMException: 80020005: Type mismatch.
