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)
    {

        try
        {Checkofflinestatus();
            bSuccess = pFile->SendRequest(strHeaders, NULL, 0);

        }
        catch (CInternetException* e)
        {
            TCHAR szCause[255];
            szCause[0] = _T('\0');
            e->GetErrorMessage(szCause, 255);

            strResponse = szCause;
                        e->Delete();
            pFile->Close();

Can u tell me reason for error
