Summary: Problem with Internet Exceptions !
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2

Hello.

I have the following code compiled with Visual C++ 6.0 and it run very well
under Wine in Linux until i disconect the Ethernet Cable from the PC and cut of
the connection to the Internet manually.

If i make the same thing with the Programm in windows then the Programm does
immediatly go (less then a Second) to the CInternetException Routine and Catch
there the Lost and Timeouted Connection.

Under Wine the Programm wait about more than 70 Seconds till it show the Message
from the CInternetException Routine.
After this the Programm is for about 60 seconds totally Blocked and crash then
with a Error Message from Wine.
> From my side of View something with the Implementation of the function

"CInternetException" is wrong.
It wait extremly long till it catch the Timeouted Internet Conection block then
the Application Totaly and Crush it after this the Application.

Here is the little Programm code which i use for Compiling it under Visual C++
You need the following two DLL Files if you want it to run under Wine additionaly

MFC42.DLL
MSVCP60.DLL

if(ReadToken_i!=0)
    			{
    				Puffer[ReadToken_i]='\0';
    				strcat(Buffer,Puffer);
    			}

}
    		while(ReadToken_i!=0);

HttpFile->Close();
    		delete HttpFile;

    		e->Delete();

Sleep(1500); // Sleep 1500 before the Next Reload of Data

}
    while(!kbhit()); // Repeat until a Key is Pressed

    InternetSession->Close();

delete HttpConnection;
    delete InternetSession;
