Re: Unhandled Exception in XMPP (General questions)

Also if i comment the statement which was causing the unhandled exception, It went on and ask for login and password, After that it ask for to whom i need to send the message and what, after providing the details it calls SendText but i get following error message

The value of ESP was not properly saved across a function call. This is usually a result of calling a function pointer declared with a different calling convention.

Here the whole code

[code]
//#import c:windowssystem32wodxmpp.dll no_namespace named_guids
#include wodxmpp.tlh

#include <atlbase.h>
CComModule _Module; // dummy required to utilize atlcom.h
#include <atlcom.h>

bool error = false;

// Define the wodXMMP events to be handled:

_ATL_FUNC_INFO OnConnectedInfo = {CC_STDCALL, VT_EMPTY, 0, VT_EMPTY};
_ATL_FUNC_INFO OnDisconnectedInfo = {CC_STDCALL, VT_EMPTY, 2, {VT_I4, VT_BSTR}};

{
m_pwodXMPPCom = pwodXMPPCom;
DispEventAdvise ( (IUnknown*)pwodXMPPCom);
}

virtual ~wodXMPPEvents ()
{
DispEventUnadvise ( (IUnknown*)m_pwodXMPPCom);
m_pwodXMPPCom.Release();
}

void __stdcall OnConnected ()
{
printf(

);
}

void __stdcall OnDisconnected (long ErrorCode, BSTR ErrorText)
{
if (ErrorCode)
{
error = true;
_bstr_t err(ErrorText);
printf(

, (char *)err);
}
else
printf(

);
}

//pXMPP->Contacts->Add(_bstr_t( someone@wippien.com ))->Subscribe(); // you can add someone to your contact list...

//Now here it shows the error message.

Looking forward for quick reply..

Thanks.
