Hi Luc
I undestand that AppendText do something with memory or other objects ...
And GC can work later. 
Please note that my lalest source code does not call TextBox.AppendText(..)
and does not change Text property of control at all. But Handles are leaking!
It seems like leak is not related with Text property or with AppendText() method of TextBox class.
Problem with cross threading call.
It's very strange.
Anyway thank you very much!

Interesting!
I can't get it to work at all with AppendText. If I use
textBox1.Text += text;
then the handles count up to 155 then reset down to 145 and repeat. Presumably they're being mopped up on garbage collections, so they don't really leak.
Weird.
Regards,
Rob Philpott.

Hi Rob
You are right. It's very interesting.
I see leak even when I don't change Text in the control.
Please see my more detail reply to Luc above.

I have done more tests.
It seems like Handles counter grow up from 150 up to 2500 value.
After 2500 it resets back to 200 handles and increases again to 2500 and so on.
It is stupid behavior. Why "textBox1.Invoke(d, arg);" call takes system resourse (Handle).

Hi Folks,
I would like to make an application to access a network camera(separate IP, AXIS communication device) using C#. I just need to play the video on my desktop and not saving or anything.
I am new towards (High Level or dialog based)windows software development, so please help me and would be nice with some sample code examples.

Hi,
two suggestions:
1.
when new to a combination of issues, get acqainted to each of them individually.
So start creating a very simple app, then add the things you will need one by one.
2.
Look around either here at CodeProject or ask Google.
These are some camera related articles[^].
Hope this helps.

Hello!
You need to create the small client application that caputures the
current desktop using GetWindowDC and GetWindow API.You can save these
bytes or send it to your sever application using SendMessage or by using
the sockets.

He just told you. If you can't understand what he said, then you probably can't get what you're looking for.

I am using VS 2003 to debug an web application.
It works well sometimes, but sometimes it does not. The status bar shows "Setting up server for debugging". It just keeps setting it up forever. I have also put localhost in the trusted sites but no help.
what can be the reason??
|
|
|
|
|
Well, it could be that VS2003 is as flakey as hell when debugging web projects on IIS. This happens to me all the time and I've just got used to either firing IISRESET from the command prompt or killing the ASP.NET worker process from task manager.

Well, I am new to this. Does this mean that have no ti live with this and that I just cannot do anything about it?

If its the same problem I have then you may have to get used to it. I think its something to do with shadowing in IIS which is a feature where you can deploy stuff to IIS without a break in service. Maybe you can switch it off - I haven't looked. First off, determine whether doing IISRESET after a build stops this problem or whether its something else.

Hello everyone,
I am looking for two tutorials, one for C# XML and the other for C# thread. I have performend search, but all I found are comprehensive ones, which involves other materials making the samples too big.
Do you have any ones to recommend which are dealing with pure XML rendering and pure threading control s much as possible?
BTW: I am a beginner with C# and my book does not cover the two topics too much.
thanks in advance,
George

Neither is very specific to a language. XML is a standard there is DOM API and SAX API they are very similar in every language I have used them in. Threading is threading and again not language specific. If you learn the concepts it is very simple to translate the language specific tools for your needs.
www.w3schools.com might have some short tutorials and samples on XML etc. If you do much work with XML you also need to learn XPath which you will also find there. You might also try Wikipedia for anything you need a basic introduction into.
For threading there is a site that people frequently give as a good location for learning. I don't remember it but if you search in the C++ / MFC forum you should find where people have given the URL. When I was trying to get a handle on threading I read Advanced Windows by Richter. I believe he has a .NET or even C# book out now that likely has similar threading coverage in it from the .NET platform perspective.
good luck

Thanks led mike,
1. For XML, I do not mean the basic concept, I mean how to use C# XML SDK/API. Any ideas or recommendations?

MFC forum? Confused? Do you mean C++ threading or C# threading? Could you give me some hint about what you mean please?

I don't know about XML, but there's an excellent (and free) e-book on threading in C# here[^]. It's the first hit you get on google actually, so you might have found it already. I suppose it does require you to have some basic skill when it comes to c#, but I wouldn't recommend starting with threading when you're new to c# anyway. Good luck.
Standards are great! Everybody should have one!

Thanks Bekjong,
Cool book!! Thanks again!!
For XML, I do not mean the basic concept, I mean how to use XML lib/API in C#. Any ideas?

You're welcome. I hardly ever use XML, except perhaps for object (de)serialization, which you can find more about here[^].

Thanks Bekjong,
Cool. What I want to learn is how to generate XML message and parse XML message. Seems a little different from the link. Thanks all the same. Let me know if you have good idea later.

hi,
I want to know how to add animation to windows application
Animation ( swf file ..)
Please tell in a step by step format .
Thank You

Well, if you want to add a .SWF file then the easiest way would be to insert a web browser control, and have it load the flash file.
So, in a step by step format:
Open code
Go to designer
Insert WebBrowser control
Set Url to path to the .SWF file
Run tha app
My current favourite word is: Nipple!
