link error with msxml http request on winCE pocket PC

Please assist. I'm getting this link error caused by the
iXMLDOM function ->open(...

two errors
1)
error LNK2019: unresolved external symbol "void __cdecl
_com_issue_error(long)" (?_com_issue_error@@YAXJ@Z)
referenced in function "unsigned short * __cdecl
loadAssignment(int)" (?loadAssignment@@YAPAGH@Z)
2)
error LNK2019: unresolved external symbol "unsigned short
* __cdecl _com_util::ConvertStringToBSTR(char const *)" (?
ConvertStringToBSTR@_com_util@@YAPAGPBD@Z) referenced in
function "unsigned short * __cdecl loadAssignment(int)" (?
loadAssignment@@YAPAGH@Z)

I've got these libraries in use :UUID.LIB and wininet.lib
and ole32.lib and oleaut32.lib

And header
namespace MSXML
#include
{
<msxml.h>
}

and code snippet :
hr = CoInitializeEx(NULL,COINIT_MULTITHREADED);
if(!SUCCEEDED(hr)) return 0;

hr = CoCreateInstance(MSXML::CLSID_DOMDocument,
NULL, CLSCTX_INPROC_SERVER |
CLSCTX_LOCAL_SERVER,MSXML::IID_IXMLDOMDocument, (LPVOID *)
&iXMLDoc);



if(iXMLDoc)
{
iXMLDoc->put_async(VARIANT_FALSE);

// Pocket PC requirement:
// Remove document safety options
IObjectSafety *pSafety;
DWORD dwSupported, dwEnabled;

if ( SUCCEEDED(iXMLDoc->QueryInterface
(IID_IObjectSafety, (void**)&pSafety)))
{
pSafety->GetInterfaceSafetyOptions
(
MSXML::IID_IXMLDOMDocument,
&dwSupported, &dwEnabled );
pSafety->SetInterfaceSafetyOptions
(
MSXML::IID_IXMLDOMDocument,
dwSupported, 0 );
}

vXMLSrc.vt = VT_BSTR;
//
http://169.254.139.171/scripts/easyvoice.exe?
user=dave
// vXMLSrc.bstrVal=SysAllocString
(L"http://169.254.139.171/scripts/easyvoice.exe?
user=dave"); // url for xml document
pXH->open(L"GET", gszPOSTURL,_variant_t
(VARIANT_FALSE), _variant_t(""), _variant_t(""));
pXH->setRequestHeader(L"Content-Type",
L"text/xml");

pXH->get_statusText(&bStr);

Thanks for taking a look !!

Hi

_com_issue_error is not implemented under Windows CE 3.0 since the compiler
does not support C++ exceptions. Have a look at the article below for
details.
