Re: how can i send data by using connection of another program?

your app is a game? if so then why do you not do the connection within your own app?

Unless of course your just trying to capture packets and manipulate them from some other game, i.e. some sort of hacking ability...

Last time I did anything like this I had to create an NDIS driver and capture the traffic at the network card. This is not for the faint of heart and if you mess it up you are likely to pull down the entire operating system.

Hi I have used multithreading for udp client/server communication.When i run the server both the threads are executing at the same time.So i used a Thread.Sleep() after the 1st thread.So the 1st thread works properly.When it comes to the 2nd thread it gives"the existing connection was forcibly closed by the remote host".Can you please give me your suggestion

is it because thread 2 is being called from in thread 1? it would be better if you could post some example code

Sorry i didnt read the exception in your OP. That exception says that there is a problem with the host you are connected to. i.e. the server. This means the server is cancelling the connection for one reason or another, it could be your server is limiting connections to just one (your first thread) and thats why the second fails. I cant help much with this kind of thing, but you basically need to look at settings on your server somewhere.

I think your problem may be that you do not know that difference between C# and Java. more specifically on the level of how they are spelt differently.

WebBrowser and AxWebBrowser differences

Member 465172917-Mar-09 3:14

Hi all,

I'm using the WebBrowser control. When I'd like to page down if I write something like;

webBrowser1.Document.Window.ScrollTo(0, y) ; // it is ok no problem

and also I can get easily ScrollBar lenght like;

scrolHeight= webBrowser.Document.Body.ScrollRectangle.Height // it is ok.

But I'm using the AxWebBrowser object which helps me much more than Default webBrowser control in C#.

So How can I do those.

Thanks.

I'm sorry about that.

I'd like to learn how can I do these using AxWebBrower.

1-) webBrowser1.Document.Window.ScrollTo(0, y);
2-) scrolHeight= webBrowser.Document.Body.ScrollRectangle.Height;

Thanks.

Modifying Windows Service app.config file

User 265531917-Mar-09 1:57

User 2655319

17-Mar-09 1:57

Hi all,

I am developing a Windows Service. This Service connects to a database and on every timer_tick retrieves new records from a database. The ID of the last record retrieved is being saved to the app.config file using the code below:

private void UpdateConfigFile(Int32 lastIndex)<br />
{<br />
      Properties.Settings.Default.LastRecordId = lastIndex.ToString();<br />
      Properties.Settings.Default.Save();<br />
}

The service works fine and on every timer_tick it picks up only the new records from the database, but if I open the <projectname>.exe.conifg OR <projectname>.vshost.exe.config the LastRecordId value is always 0. It seems like it is storing and reading the config file from memory or something.

Any help would be greatly appreciated Smile | :)

from memory the config file is a read only document for use in the program so no changes are stored to it. Plus if you change it outside the program while the program is running you need to restart the program for the new readings to take place.

You could save the value to another file that is pointed to by the config file.

So it makes more sense not to use the .config file in the first place for settings as these, and opt for a normal text file.
Correct?
