posted January 17, 2004 3:15 PM Due to the limitation of data base licenses I will sometimes get a message box appearing stating "An Existing connection was forcibly closed by host" when running emulation tool. My question if where can I handle this error at. After I click Ok button, I get a .net unhandled error dialog message. I want to handle this case. |

posted June 25, 2004 7:42 PM I'm having this same problem and could not find any more info about this topic so I'm reopening this thread. I've got everything working (even by reference and adding my event handlers). Telnet.Connect() works and everything looks good until I logoff. Now from my socket programming days I know a little about what's going on here: 1) I'm ready to end my session so I enter "logoff" 2) my telnet client (Vt.Telnet) sends "logoff" to the server without knowing it's meaning 3) the server, however, sees "logoff" and says "make it so" and closes the socket connection 4) any good socket client knows that when a network receive, recv(), returns 0 that the connection was closed by the other side and the socket handle is stale. How do I detect a recv() = 0 so I can close the telnet connection? TIA, Matt |
