Are you saying you want the form's controls to have the same values the next time the user opens your app? You can save the data to a file or the registry when you exit, and simply read them when you start again.

Problem with MemorySream

Why does the following code snippet

MemoryStream stream = new MemoryStream();
XmlTextWriter writer = new XmlTextWriter(stream, Encoding.UTF8);
writer.WriteStartDocument();
writer.WriteElementString("Test", "Test");
writer.WriteEndDocument();
writer.Flush();
stream.Seek(0, SeekOrigin.Begin);
Console.WriteLine(Encoding.UTF8.GetString(stream.ToArray()));

produce the following output:

?<test>Test

The question mark at the beginning is meant.
I've tried different encodings, it does not happen with Default and ASCII.

When I use a StreamReader I can get it to work, but I will understand where the problem is.

Let me try that piece out... Looks interesting. It has something to do with the number of bytes in a character. The "old" ASCII uses 7 bits, while UTF8, you guessed it uses 8 bits. But it doesn't really explain why you get the weird character at the beginning.

Have you tried looking up some info about text encoding on google?

Yes, I've tried to find some hints on Google but without success.

Console.WriteLine(new StreamReader(stream).ReadToEnd());

works correct.

when you create a stream or file in UTF8 or in Unicode, it will start with a 2-byte
indication of the encoding; in your case it is 0xFE 0xBB. Only then will appear the
first "real" character (0x3C for <).

If you write to file, then open the file in a text editor, both cases work just fine,
because the editor consumes the optional 2-byte to understand how it needs to interpret
the remainder.

Your reading code however does not discover the encoding, it has that information baked
into the code, so it treats the 0xFE oxBB as real characters and since they are not
really printable (above 0x7E), it turns them into a single question mark.

it doesn't have any special algorithm. you can use .net methods (antialiasing enabled) to do it.
simply create a panel and on paint event use e.Graphics.DrawImage() method to draw your image in your panel that larged according the zoom when e.i. + key pressed.

Hi, thanks a lot for your reply. Actually I am using the same method as you have described but it is bit slow and getting complex. Because I have to draw the whole drawing again. Have u seen such kind of code or any sample. Plz let me know I will be very thankful to you.

Hi there,
I encountered some authentification issue.I have a window application in C#, having program which is calling web services, but I receive a log file said "Error Message: The remote server returned an error: (401) Unauthorized.". What I need to do is to pass credential of NT Login ID and password, then only I am able to access the websservice. Can anyone walk through my coding, any line or command is missing? How i can pass the credential along?

...
string boundaryString = Guid.NewGuid().ToString("N");
string boundaryLine = "--" + boundaryString + "\r\n";
Uri uri = new Uri(requestUri);
HttpWebRequest request;
request = (HttpWebRequest)WebRequest.Create(uri);
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.ContentType = "text/plain; boundary=" + boundaryString;
request.Method = "POST";
...

thanks,
Lee Chuang

Thanks for reply. The content of the link is talking about the using Client Certification. But over my side, I am using service account (NT Login Account) for the credential. My NT login is known by the opposite server. So when I run the web service, remote server knows my present to the service. But bad news is I am not sure how to make my code carry along with the credential.

really need more help...

thanks,
Lee Chuang.

Hi,

I am a self taught programmer who just knows there must be a simpler way of doing this:

<br />
      DataRow[] drx = this.myWebLoggerDataSet.Tables["MonitorList"].Select("DBMonitorNumber = '" +gbi.ToString() +"'");<br />
      gbMonitoredItem[gbi].Text = drx[0]["Name"].ToString();

Surely I don't need to use a DataRow to achieve this?

I can't figure out anything simpler though.

TIA.

If I'm not missing something, then there is really no simpler way as long as you stick to untyped DataSets.

With a typed DataSet it would be a bit simpler:
gbMonitoredItem[gbi].Text = this.myWebLoggerDataSet.MonitorList.FindByMonitorNumber(gbi).Name

In typed DataSets you have also the possibility to add your custom code (partial classes).

He'll still have to deal with DataRow objects (or rather objects derived from DataRow) at some point - it will just be hidden away.

Ok - that fills in the gaps in my broken knowledge Smile | :)

I could use that but I would need to index that column etc so at the end of the day it's probably just as easy to do it "the long way".

Linq does look to be the eventual simplification.

Thanks for the pointer - much appreciated.

It seems sensible for me that the Select method returns an array of DataRow objects.

Because it isn't available yet. LINQ is probably what you are looking for. It will be available in Visual Studio 2008 ("Orcas")
