Hello everybody,
Basically the problem is that the UTF8Encoder is not able to get this char '²'.
Is this a known fact, or am I doing something wrong?
This is what I do in a test routine:
using (FileStream fs = File.OpenRead(filename))
{
byte[] b = new byte[10000];
UTF8Encoding temp = new UTF8Encoding(false,true);
int l=0;
FileStream fw= File.Open("copy.txt",System.IO.FileMode.Create);
while ((l = fs.Read(b,0,b.Length)) > 0)
{
string s= temp.GetString(b, 0, l);
Console.WriteLine(s);
}
fw.Close();
}
Thanks for your time and help
All the best,
Martin

Can your console output the character even if it is read correctly? If your console code page does not support it your program won't display it.
UTF8 is multibyte, so your read operation might split the byte stream in the middle of a character. Create a StreamReader with Encoding.UTF8 to avoid having to deal with this manually.
Edit: Are you sure your file is actually UTF-8 encoded?

Hello,
First, thanks for youre time!
Actually I started by using a StreamReader, with the result that the complete line was there but without the '²' character.
Any other suggestions?
All the best,
Martin

First of all, check the source file (in my experience the most likely error). The character should be encoded with the byte sequence C2 B2.
As a quick hack to test it rename the input file so it has a bin extension and load it in Visual Studio - you should now see the byte content in a hex format.

Hmm,
I did the test with following result "B2" and no character is shown.
When I open it with the "TotalComander" Bin style, it's also "B2" but the '²' is shown.
So uses UTF8 really multibyte, or only for special characters?
Thanks again for your time and patiance.
All the best,
Martin

UTF-8 use more than one byte for anything over Unicode character 127. Some refers to these as special, others refer to English characters as special.

Hello,
It really looks like the file isn't really UTF8. (It's a XML file with a discribtion that says its UTF8 formated  )
But I don't know wich encode I have to use.
Is there a way to find this out?
All the best,
Martin

Yes, this is seen before - it's an invalid XML file, a lot of programs spit those out. 
A fair guess is the local ANSI codepage whereever the file was saved. For most Western European languages, this would be the Windows codepage 1252 (or use Encoding.Default if the encoding is the same on the machine reading and writing the file).

Thanks very much!
I'm now using the GetEncoder method, and "Windows-1252" as the parameter.
All the best,
Martin

Use Timer in Windows Forms. If event "tick" comes, then close your form.

You could always use sleep.

If you're using Framework >2.0 you can use the MaskedTextBox control.

Hello,
You need to handle the KeyPressed event or override the OnKeyPessed in your TextBoxControl which inherits from TextBox.
there you have to compare the "e.KeyChar" with the "," or ".".
if (e.KeyChar == ',')
{
if(this.Text.IndexOf(',') > -1)
{
e.Handled = true;
}
}
Hope that helps!
All the best,
Martin

If you have many different combinations to cater for, then patterns and regular expressions may also help. I think I have once used regular expressions for similar problem in the past...

I want to gather data from this page:
http://moneycentral.msn.com/investor/StockRating/srstopstocksresults.aspx?Score=10
and process it in C#.
The problem is the page content is loaded via scripts (I think) and the page's .html source does not contain the data. So my initial idea of getting and processing the page's .html source won't work.
Manually typing Control-A Control-C and pasting into a text document would work, but I'd prefer an automated solution.
A. Is there an easy way to actually handle the scripts from within C# (or .NET in general)?
OR
B. I've never done control of another program through C#, although I understand that .NET allows this. Can my browser be controlled to send me the text or save it to a file?
OR
C. Perhaps a FireFox plug-in should be written? (I've never written a plug-in before, either.)
Suggestions would be appreciated.
Thanks,
Mark

Try System.Net.Webrequest .. to create a request for the page, and if you're not sure of a correct response, use WebResponse.GetResponseStream() to process the response

Thanks for the try, but this just retrieves the general page setup and the scripts themselves... none of the data that is displayed on the page is in what is obtained. (I do really appreciate the pointer to these functions, however. I need them for another project I have in mind!)
Still looking for a solution.

Maybe you can be a little more specific about the "data" you are looking for. I'm assuming you need the items displayed in the 6 column result table on the page ?

Sounds like it uses AJAX to retrieve the data?
Maybe you could see what URL is being called by the script from the page source?
