UTF-8 is an encoding of Unicode, so any Uncode character can be stored in UTF-8.
I don't know exactly what you want to find out, but perhaps the Char.IsSurrogate method is something that you are looking for.

b { font-weight: normal; }

Thank you.
I find the Char.isSurrogate() always return false, such as Char.isSurrogate('a'),Char.isSurrogate('10') all return false.
but it give me the right way, and I read the topic of Char class,
and find follow code can answer my question:
Char.GetUnicodeCategory(char1)==System.Globalization.UnicodeCategory.OtherLetter
when char1 is a Eastern character, it return true.

Hello
string SystemPath = Environment.GetFolderPath(Environment.SpecialFolder.System);

It isn't recommended to save files in the system directory and running under Vista it isn't allowed unless you are running with specific elevated privileges (usually only given to installer apps.)
The correct way to find it is
Environment.GetFolderPath(Environment.SpecialFolder.System)

Hi all,
How would i go about trimming the first character in a string?
Example: I want to add "+27" to the Variable that contains "0721234567". But first i need to delete the "0" from the Variable. So then the Variable will contain "+27721234567".
Thank you in advance.

hi
dim str as string = "0721234567"
dim strNew as string = str.Substring(1)
str = "+27" & strNew

Ok
<br />
string strNumber="0721234567";<br />
string strPreCode="+27";<br />
strNumber = strPreCode + strNumber.Substring(1,strNumber.Length-1);<br />
this code add PreCode(+27) to first of Number(0721234567), but first remove zero(0) from first position of Number.

Hi,
Can anybody help me to get Icon details like its name, target path, working directory whenever it is double-clicked to run the application. This is be using Windows API or in C#.
I have already used IShellLink Interface but its been hard-coded for icon name. Suppose the user changes desktop icon name then also coding should be able to change its working directory. This can be done if I can check the existence of the icon.
Regards.

I think you are talking more about shortcuts?? You mean those on the desktop?
If you want to enumerate the links on the desktop:
Directory.GetFiles(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "*.lnk");
Now, shortcuts are .ln; files and inside them you'd find the path to the program they excute. Read them using as FileStream, then use a Regex to find the text of the exe file, and/or anyother details you want.
Regards

I am new on c# ... switched from Delphi, and making windows application using C# + SQL Server 2005.

If you're using VS2005 (Any edition) you might want to setup the columns of the datagridview by hand. The control allows different kinds of columns to be setup (Checkbox,TextBox,ComboBox,Button,...) [^]
Locking a row in a datatable is not possible I'm afraid.
Instead you can use a Transaction on the database connection to lock rows and update them without allowing other clients to update the same rows. If I'm not mistaken, the DataTableAdapters to this automatically

Hi
I am developing Windows Mobile Application, I need a timer to call the callback method , I have used the code below, it worked fine for Windows Application, but device application causing problem.
timer = new System.Threading.Timer(new TimerCallback(OnNextMinute), null,
Timeout.Infinite, Timeout.Infinite);
StartTimer();
}
const long TIMER_INTERVAL = 1000L;
private void StartTimer()
{
// set the timer to trigger an event every 30 seconds
timer.Change(0, TIMER_INTERVAL);
}
public void OnNextMinute(object state)
{
//calling method here
}
Please let me know any other way to use timer in Windows Mobile.

What are your problems exactly?
I even wonder how it worked on windows!! Why the Timeout.Infinite?? If you don't want to start the timer immediately, use -1 instead!! Also, why not setting the interval directly -again Timeout.Infinite!!- instead of assigning it to a constant at runtime??
