Calling WDS Programmatically from C++

Hi all,

I was trying to get WDS queried from C++ for a whole day and it's
pretty clear
I need some help Since I'm Java developer, this is probably trivial
for you.

Here's scenario: i got VC++ express 2005 from
http://msdn.microsoft.com/vstudio/express/visualc/ and than platform
SDK as
explained at
http://msdn.microsoft.com/vstudio/ex...alc/usingpsdk/
and finally WSSDK from http://addins.msn.com/support/WDSSDK.zip

Btw, why VC doesn't save directory settings for exec,include and lib
files when
I add them via Tools/Options/Projects and Solutions/VC++ Directories/?
I have to add them every time i start VC or edit manually
VCProjectEngine.Dll.Express.Config

Now, new Win32 console app project is created. wdsQuery.h and
wdsQuery.idl were added from
And add/existing item... I had to turn off 'treat wchar_t as built-in
type' to solve some linking errors.
It seemed logical to add WDSSDK folder as 'Additional Library
Directories' in project settings.

I tried Brandon's example from
http://forums.microsoft.com/msdn/sho...15291&siteid=1
and 'official' example from
http://msdn2.microsoft.com/en-us/library/aa965714.aspx
but the result is the same: ExecuteQuery fails and I get some
CException in console output:

First-chance exception at 0x7c812a5b in wds_query.exe: Microsoft C++
exception: CException at memory location 0x0012e470..

here's the code:
<code>

#include "stdafx.h"
#include "wdsQuery.h"
#include <comdef.h>
#include <conio.h>
#include <stdio.h>
#include <wchar.h>
//#include <msnldl.h> //???
#include <adoint.h>
#include <adoguids.h>

HRESULT TestExecuteQuery(ISearchDesktop *psd)
{
ADORecordset *prs = NULL;

HRESULT hr;

hr = psd->ExecuteQuery( L"eclipse",
L"DocTitle,DocFormat",
L"PrimaryDate DESC",
NULL,
&prs);
if (SUCCEEDED(hr))
prs->Release();
else
printf("query has failed!\n");
return hr;
}

void queryWds2() {
SCODE sc = CoInitialize(0);
ISearchDesktop *psd = NULL;
HRESULT hr;

if (SUCCEEDED(hr = CoCreateInstance(__uuidof(SearchDesktop), NULL,
CLSCTX_INPROC_SERVER, __uuidof(ISearchDesktop),
(void**)&psd)))
{
TestExecuteQuery(psd);
psd->Release();
}
CoUninitialize();
}

int _tmain(int argc, _TCHAR* argv[])
{
char cont;
queryWds2();

printf("press enter to continue...");
scanf("%c", &cont);

return 0;
}

</code>

TestExecuteQuery(psd); gets executed but it fails ( SUCCEEDED(hr)
returns false).

What am I missing here ? Thanks in advance. Milan

p.s. I'm working on a search project where we have to merge search
results
from client's desktop and corporate server, that's why I need this.
WDS will be queried from Java actually using jawin, but I need working
C++ example first.
