Re: This application has requested the Runtime to terminate it in an unusual way

Hi,
I checked in relase version but erro didnt occur.Error occur sometime
in release exe

I think problem should be in this function as it is repeatedly call

bool CChatManager::SendRequest(CString strObjectName, CString&
strResponse)
{
CString strHeaders = _T("Content-Type: application/x-www-form-
urlencoded");
        CInternetSession pSession;
        strResponse = _T("");
        CHttpFile* pFile = NULL;

        char* szBuffer = NULL;

        //Here the virtual directory will be appended with query
string
        strObjectName = m_strVirtualDir + strObjectName;

        CHttpConnection* pConnection;

        if(m_bSecureMode)
        {
                pConnection = pSession.GetHttpConnection
(m_strServerName,
INTERNET_FLAG_TRANSFER_ASCII, 443, NULL, NULL);
                pFile = pConnection->OpenRequest
(CHttpConnection::HTTP_VERB_GET,strObjectName,NULL,
1,NULL,NULL,INTERNET_FLAG_DONT_CACHE|INTERNET_FLAG_SECURE);
        }
        else
        {
                pConnection = pSession.GetHttpConnection
(m_strServerName,
INTERNET_FLAG_TRANSFER_ASCII, 80, NULL, NULL);

                pFile = pConnection->OpenRequest
(CHttpConnection::HTTP_VERB_GET,strObjectName,NULL,
1,NULL,NULL,INTERNET_FLAG_DONT_CACHE);
        }

        if (pFile)
        {

                        strResponse = szCause;
                                                e->Delete();
