Re: [twsocket] THttpCli exception errors
I have tried assigning a procedure to handle this exception using your suggestions, using this code: - HttpCli.CtrlSocket.OnBgException := ExErr; ... procedure TForm1.ExErr(sender: TObject; E: Exception; var CanClose: Boolean); Begin try CanClose := False; Label1.Caption := 'Exception error.'; except end; End; - The error still persists, though, and remains to crash the app. Is there another way to go about this error handling?

Re: [twsocket] UDP Newbie...
Hello Mark, If I call listen and then try to send I get an error 10049 (Bind Address not available) Are you sure you filled in the correct IP? If I call connect and then send, I see the data at the other end but I do not get any response in the DataAvailable callback. No because of the error in previous paragraph it will not listen. If I open a second TWSocket to listen I get a callback. So that is strange. Do you create all in code or do you have TWSocket component on your form? If the latter then I suggest to delete it and try with a fresh one. Maybe you have changed some properties and have a conflikt now. keep a copy of it to check later what exact was changed ! --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] THttpCli exception errors
Hello, The error still persists, though, I don't see your original post. Can you tell me what the error is? and remains to crash the app. What do you mean by 'crash'? Is there an exception error, is the application non responcive, something else? Is there another way to go about this error handling? If you run in the IDE and set 'stop on delphi exceptions' ehen then debugger stops and you can check the callstack and others to see what is wrong. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Tuesday, April 1, 2008, 08:28, [EMAIL PROTECTED] wrote: I have tried assigning a procedure to handle this exception using your suggestions, using this code: - HttpCli.CtrlSocket.OnBgException := ExErr; ... procedure TForm1.ExErr(sender: TObject; E: Exception; var CanClose: Boolean); Begin try CanClose := False; Label1.Caption := 'Exception error.'; except end; End; - The error still persists, though, and remains to crash the app. Is there another way to go about this error handling?

Re: [twsocket] UDP Newbie...
If I call listen and then try to send I get an error 10049 (Bind Address not available) Are you sure you filled in the correct IP? As an additional note: You can probably set the IP string of the server socket to 0.0.0.0 which will listen on all available interfaces. So you don't have to find or configure the appropriate local interface address. Allowing the user of the program to change that interface address is helpful, though, as someone might have two network cards built-in connected to two different networks and wants to attach your application only to one of the networks.

Re: [twsocket] UDP Newbie...
Hello Wilfried, Are you sure you filled in the correct IP? Yes. Do you create all in code or do you have TWSocket component on your form? On the form. I deleted the original component, put a new TWSocket on the form, set the addr to 192.168.245.2, set the proto to udp, called listen, called Send and got the bind failure. Calling connect instead of listen and then send performs without error. I see the data on the other computer. So, it appears UDP does require two TWSocket. One to send and one to listen. Ideas?

[twsocket] Connecting and Disconnecting
Hello What is the implication on the TCP control of disconnecting and connecting using the same TWSocket object? what I mean is that: FSocket.Disconnect; FSocket.Addr := 'x.x.x.x'; FSocket.Port := '80'; FSocket.Connect; What is the implication of doing that on sequence?? I ask that because we are having some problems with the server machines (Server is not ICS), apparently it keeps the connection on it´s memory and after a lot of connections and disconnections it stop working (The host device) because it has a lot of half-closed connections. This is the right way of reconnecting? If not, what should be the best? Try to reconnect on the OnSessionClosed? Thanks!
