Thanks Dave I will look at it...

Hello,
Is it possible to use the GridView Component in VB.NET?
If yes how can I add it to my project?
Thank you,
Eric H.

Which version of VB.NET (.NET Framework) are you using? GridView showed up in the .NET Framework 2.0, and it should be in the ToolBox. You add it to your Web Form just like any other control.
Anything further and you'll have to provide more detail as to what the exact problem is.

I am using VB.NET (Framework 2.0)
The problem is this component is a web component. Therefore, I don't see it in the toolbox list. I tried to add it as a part of the toolbox but I didn't success.

If your writing a Windows Forms app, then it wont show in the ToolBox. GridView only works in an ASP.NET app. It's in the ToolBox under the Data tab ... or did I miss something in your posts??

This is the first time you mentioned that.

Windows Forms uses the DataGridView. Again, under the Data tab in the ToolBox.

The Web has thousands of them. All you have to do is Google for "VB.NET DataGridView tutorial".

Use the Replace method of the String class, see [^].

You can't actually change a string. The Replace method returns a *new* string with the values changed.

Hi,
How can we get data or characters which is present on image.Actually i have captcha images in .JPEG extension and from that images i have to remove noise, extract the characters and then i have to convert the extracted characters in to string.So please give some idea how to proceed further.
|
|

|

There's a reason why it's noisy and distorted. It's so that you CAN'T use automation to get those characters!

What did I just get done telling you?? You CAN'T DO THAT because CAPTCHA was designed specifically to defeat what you're trying to do!

What part of "YOU CAN'T DO THAT" don't you understand?
The text in those images is deliberatly wavy a filled with noise so that no OCR software can read it. You can't get the text in a CAPTCHA image because there's no technology out there that can read it!
That's the whole point behind CAPTCHA!! It's a test to determine if a machine is trying to access a website or if its a human doing it. The machines will always fail this test because there's no way they can make out the text in the image.

I am sorry Dave, I am afraid can't do that.

No, you haven't understood. The whole purpose of captcha images is to ensure that it is a human that is viewing the image. They are specifically designed to make it impossible for any kind of automated tool to extract the data.
So, not only is it as impossible as makes no difference, you also can't really have a good reason to be doing it - attempting to bypass security controls is a bad thing.

As Dave and Nish have said, CAPTCHAs are explicitly designed to defeat OCR. It may not be totally impossible, you're going to have to do a good amount of research to try and process them. Noone has written a CCaptchaOcrConverter class that you can just copy/paste into your application.

PS IF you don't even know all the right questions to ask, you're probably not the right person to be doing the actual research either.
