you may use only a part from it, or remove the dashes.
Also you may use different formatters:
.ToString("N")
.ToString("D")
.ToString("B")
.ToString("P")
Do you want to be nice and simple to guess (the algorithm), or really random and good for security?

i need to use it in url so i need it more nicely
|

and look in youtube http://www.youtube.com/watch?v=1GCqDiLX1dI. so the question was how to make like in youtube
|
|
|
|
|
you may use a few chars from a guid.

Just create a loop that creates random characters from 0-9 and a-z and A-Z. Then combine them for the specified length.

I would imagine that 3Ie7Y3GHayk may resolve into something less than random.
Could just be base 26 or 52 integers.

If you don't ask questions the answers won't stand in your way.
Doing a job is like selecting a mule, you can't choose just the front half xor the back half so when you ask me to do a job don't expect me to do it half-assed.

Having also numbers, I guess it's a base-62 number.
Making some calculation, 11 base-62 digits are roughly equivalent to 64 base-2 digits.
So I guess that a code like 3Ie7Y3GHayk is a base-62 encoded Int64 value.
A guid is 128 bits, so, if you want to generate this code starting from a Guid you must use half of it. I'm not sure that doing so introduces the risk of conflicting ids.
If you want something quick&dirty, you could try the following code (I used base64 that is directly provided by the framework, but keep in mind that the resulting string can containg characters like '/' or '+' that might cause problems when put in urls). Otherwise you must write your own encoding algorithm.
Guid guid = Guid.NewGuid();
byte[] guidArray = guid.ToByteArray();
byte[] halfArray = new byte[8];
Array.Copy(guidArray, halfArray, halfArray.Length);
string id = Convert.ToBase64String(halfArray).Substring(0, 11);

The problem with the grid is scalability from the randomness. That is why I suggested they probably aren't using a random number.

Yes, probably is a database index encoded in string format.

A guid has a specific format; I wouldn't call the code that youtube uses a "guid", even though they use it for identification.
You can use the random-function to create a random string with a given length, store it in a database, and make sure that you don't issue a double. Would that suffice for identification?

Hi, is possible to get the ThreadId of the window if i know the IdProcess?
thanks. Bye Bye
|
|
|
|
|
Hi,
well...based on the processId you can get the Process, by using Process.GetProcessById(idProcess). Then, use Threads property of the process object to get all the ProcessThread's.

ok I have understood, but at the moment of lunch Process (Process.Start()), i can get the process id, but not the specific ThreadId of the window. There are many threadId when i call ProcessThread's...how can i find the ThreadId of the window?
thank you Calin.

May I ask you what do you want achieve with that thread?

Ok i try to explain my problem...
I made a sample application: with a button open a folder
(sorry for italian comment but i'm italian)
if (!IdProcessoCartellaDati.HasValue)
{
if (Processo == null)
{
// istanzia il processo
Processo = new Process();
// nome del processo
Processo.StartInfo.FileName = "explorer.exe";
// la cartella da aprire
Processo.StartInfo.Arguments = "C:\\Temp\\Log";
// controllo di eventuali errori
Processo.StartInfo.ErrorDialog = true;
Processo.StartInfo.ErrorDialogParentHandle = Handle;
Processo.StartInfo.UseShellExecute = true;
try
{
// esegue l'apertura della cartella
Processo.Start();
// memorizza l'id del processo
IdProcessoCartellaDati = Processo.Id;
}
catch (Exception)
{
// gli errori sono gestiti da Windows
}
// rilascia le risorse
Processo.Dispose();
}
}
else
{
Processo = Process.GetProcessById(IdProcessoCartellaDati.Value);
// ripristina la finestra (dimensioni)
ShowWindow(Processo.MainWindowHandle, SW_RESTORE);
// e la porta in primo piano
BringWindowToTop(Processo.MainWindowHandle);
}
This solution it's ok, but if i close the application with a explorer open on the specific folder, if i execute the appication again at the first click event Vista open another explorer window (and it's correct) but if i click again ,Vista open another window, and another...
I hope that you have understand my problem.
Thank you.
Bye Bye

there are so many child nodes in parent node. i want on the selection of child node the another form must be open.how can I do this?
|

you may use NodeMouseClick to handle the selection event.
