HttpWebRequest problem...

Hello!

Is there anything something like HttpWebRequest.Close(), but in .NET 2.0?

What's it for? I need to close HttpWebRequest. I know that when I am creating new HttpWebRequest .NET keeps the connection, but is there any way to close it?

You may set Connection property = "Close"

Yes I can, but I get exception:

System.ArgumentException: Keep-Alive and Close may not be set with this property.

But I found this:

"The "ArgumentException" will be thrown if we directly set the Connection to "Close" or "Keep-Alive". And after some further dig into the HttpWebRequest's code, I think we should use the "KeepAlive" property instead of the "Connection" property to set the Connection header. For example:

use webrequest.KeepAlive = false; // to set "Connection:Close"
use webrequest.KeepAlive = true; // to set "Connection:Keep-Alive"

And that's it! Smile | :)

I forgot that KeepAlive is set to 'true' as default Smile | :)

So when I've changed it to 'false' the connection is closing while the request and response is handled Smile | :)

Thank you very much Smile | :)

Yeah, KeepAlive solves the problem.
No problem.

I found another solution.
In fact it closes all connections that are in HttpWebRequest's connectionGroup but it is that what we are looking for Smile | :)

So, you can do it like this:

wreq.ServicePoint.CloseConnectionGroup(wreq.ConnectionGroupName);//where wreq is HttpWebRequest object

I think you can use it instead setting KeppAlive to false Smile | :)

Of course we are talking about .NET 2.0. In 3.5 this is not a problem at all.

No-one can tell you, since there aren't any people here that can read your mind. What's the "handwriting interpret" library called?

Once you found this name, prepare to give answers to questions such as;
- Where's the code you tried on this library
- What error-description did the library return
- What color does an apple have?

handwriting interpreter = OCR

Check this: http://www.codeproject.com/KB/dotnet/simple_ocr.aspx[^], its more complex based on neural networks.

Mea culpa, I misread and have a bad temper. Bad excuse, I know Sigh | :sigh:

The Neural Network could easily be trained well, or read this[^] article about using the Office-component for OCR.

So the picturebox does fire the event when you move the mouse? What do you mean by "no info", does e equal "null"?

It's useless to stand in a street and fill a sentence or two with keywords, waiting for an answer - unless you want to talk to God.

Back to your question; there isn't a default design for handling 2-way sms. In fact, you can send and receive messages without using a database. So, if your specs say that a database is needed, ask yourself "why".

What facts are you going to store in that database? Make a list, please - then search Google or CP for "normalization principles", and convert your list to a design.

You need to reencode the video and overlay the watermark on it.

Wow - this is an old question. You need to reprocess the video, and put the watermark on top. That's if you want a video file to contain a watermark, you need to put it there. If you just want to SHOW it with an overlay, you can play it using WPF.
