Error calling COM-component Sapgui.ScriptingCtrl.1 (OpenConnection)

Question

Hi, All !
#include "stdafx.h"
#include "wtypes.h"
#include "atlbase.h"
int _tmain(int argc, _TCHAR* argv[])
     IDispatch *qqq = NULL;
     HRESULT hr;
     LPCOLESTR lpszProgID = OLESTR("Sapgui.ScriptingCtrl.1");
     CLSID lpclsid;
     DISPID dispid;
     OLECHAR FAR* szMember0 = OLESTR("OpenConnectionByConnectionString");
     EXCEPINFO pExcepInfo;
     unsigned int puArgErr = 0;
     DISPPARAMS dispparams;
     VARIANT dispRes;
     VARIANTARG var[3];
     BSTR cmd0 = SysAllocString(L"/H/192.168.1.1/S/3211");
     hr = ::CoInitializeEx(0, COINIT_MULTITHREADED);
     hr = CLSIDFromProgID(lpszProgID, &lpclsid);
     hr = ::CoCreateInstance(lpclsid, 0, CLSCTX_INPROC_SERVER | CLSCTX_LOCAL_SERVER, IID_IDispatch, (LPVOID *)&qqq);
     hr = qqq->GetIDsOfNames(IID_NULL, &szMember0, 1, LOCALE_SYSTEM_DEFAULT, &dispid);
     var[0].vt = VT_BSTR;
     var[0].bstrVal = cmd0;
     var[1].vt = VT_BOOL;
     var[1].boolVal = 0;
     var[2].vt = VT_BOOL;
     var[2].boolVal = 0;
     dispparams.rgvarg = var;
     dispparams.cArgs=3;
     dispparams.rgdispidNamedArgs=NULL;
     dispparams.cNamedArgs=0;
     hr = qqq->Invoke(dispid, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD | DISPATCH_PROPERTYGET , &dispparams, &dispRes, &pExcepInfo, &puArgErr);
     if(qqq)     {     qqq->Release();     qqq = NULL;     }
     ::CoUninitialize();
     return 0;
Calling of qqq->Invoke displayed this dialog box:
Error parsing sapgui commandline
'0'
SAPGUI USAGE
Syntax:...................................
and returned hr == 0x80020009 Error.....
OLE-COM Viewer say next info:
[id(0x00008096)]
GuiConnection* OpenConnectionByConnectionString(
                BSTR ConnectString,
                [optional] VARIANT Sync,
                [optional] VARIANT Raise);
In what my mistake?
Regards, Victor.

Closed !!!
     var[2].vt = VT_BSTR;
     var[2].bstrVal = cmd0;
     var[1].vt = VT_BOOL;
     var[1].boolVal = 0;
     var[0].vt = VT_BOOL;
     var[0].boolVal = 0;
