Summary: Problem with Internet Exceptions ! Product: Wine Version: unspecified Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: test AssignedTo: wine-bugs@winehq.org ReportedBy: aran@discardmail.de
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;
}

Sleep(1000); goto RELOADDATA;

Sleep(1000); goto RELOADDATA;
}
printf("%s\nBuffer\n", Buffer ); //getch(); return 0;
Sleep(1500); // Sleep 1500 before the Next Reload of Data
} while(!kbhit()); // Repeat until a Key is Pressed
HttpConnection->Close(); InternetSession->Close();
delete HttpConnection; delete InternetSession;
