Re: OpenURL chrashes

Norbert,

you were right: the * was missing, thank you.

However, there is still an issue
with the following code:

    CWnd * pWnd = AfxGetMainWnd();
    URLstatus status;
    int bufgr = 2500000;
    BYTE* buffer = new BYTE[bufgr];
    int nBytesRead = 0;

    CInternetSession Isession;

    CHttpFile* pFile = NULL;
    try
        {
            pFile = (CHttpFile*)Isession.OpenURL(URLadr);
        }
    catch(CInternetException * e)
        {
            _BrowseInfo.CSmessage = "Wrong URL: " + URLadr;
            delete [] buffer;
            if(pFile) delete pFile;
            Isession.Close();
            _BrowseInfo.i_visitedSitesSession ++;
            _BrowseInfo.i_unvisitedLinksDB --;
            _BrowseInfo.i_Imagesfound = 0;
            status.Bsucces = FALSE;
            pWnd -> PostMessage(WM_Protocol, 10, 0);
            return status;
        }

I use it in a programme with up to 60 threads to browse many websites
simultanious.
After serveral minutes with a 1 MBit connenction some of the threads
crash (Runtime error).
The code works perfect in single threaded use.
It runs also stable if the number of treads are restricted to 10.
I find it very hard to trace the reason.
Does anybody know about general limitations of multithreading?

Thanks for any hint and a happy 2008!
