I will refrain form making any comment except to point out that you have the following for loop:
for (int i = 0; i < Quescnt; i++)
and within this loop you have the following statement
Quescnt++;
Using the debugger could have helped you locate this fairly quickly.

Irrespective of this error, s/he's not going to get 6 unique random numbers from a range of only 5 possibilities.

I thought s/he's complaining that it goes into an infinite loop. There seems little point in worrying about anything else until that logic is fixed.

I thought it was going into an infinite loop because its looking for the next unique random number, and all possibilities have already been found.

In the following code:
for (int i = 0; i < Quescnt; i++)
{
int RandomNumber = RandomClass.Next(28, 33);
if (!Randomnos.ToString().Contains(RandomNumber.ToString() + ","))
{
Randomnos = Randomnos + RandomNumber.ToString() + ", ";
}
else
{
Quescnt++;
}
}
every time it hits the else clause it is incrementing Quescnt so the for loop will keep going because Quescnt will always stay ahead of the loop variable.

Now for extra credit (that is, beyond being able to blindly paste your code into this window) can you tell us why this goes into an infinite loop?
Hint:-
Documentation :Random.Next(Int32,Int32)[^]
Relevant part of documentation:
minValue
Type: System..::.Int32
The inclusive lower bound of the random number returned.
maxValue
Type: System..::.Int32
The exclusive upper bound of the random number returned. maxValue must be greater than or equal to minValue.

Hi all
on form closing event i check if it is windows shutdown and if yes i uninstall the program it is not working for me.
i tried writting to a log file on form closing event if it is windows shutdown it worked.
from another application on ckick of a button also the uninstall program worked.
plz help me
private void ChatApplication_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.WindowsShutDown)
{
Uninstall();
}
}
private static void Uninstall()
{
Process oProcess = new Process();
oProcess.StartInfo.FileName = "cmd.exe";
oProcess.StartInfo.CreateNoWindow = true;
oProcess.StartInfo.UseShellExecute = false;
RegistryKey oRegKey = null;
string sUninstallString = "";
string[] asSubKeys = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\").GetSubKeyNames();
foreach (string sSubKey in asSubKeys)
{
oRegKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\" + sSubKey);
if (oRegKey.GetValue("Displayname") != null && oRegKey.GetValue("Displayname").ToString() == "Setup1")
{
sUninstallString = oRegKey.GetValue("Uninstallstring").ToString();
break;
}
}
if (sUninstallString.LastIndexOf("exe") != (sUninstallString.Length - 3))
{
sUninstallString = sUninstallString.Remove(0, 14);
oProcess.StartInfo.Arguments = "/k msiexec.exe /x" + sUninstallString;
}
else
{
sUninstallString = sUninstallString.Replace("C:\\", "");
string sExe = sUninstallString.Substring(sUninstallString.LastIndexOf('\\') + 1);
sUninstallString = sUninstallString.Remove(sUninstallString.LastIndexOf('\\'));
oProcess.StartInfo.Arguments = ("/k cd\\ & cd " + sUninstallString + " & " + sExe);
}
oProcess.StartInfo.RedirectStandardError = true;
oProcess.Start();
oProcess.WaitForExit();
oProcess.Close();
oProcess.Dispose();
}

You need to stop the form from closing ( by setting the event args ), then close it AFTER you have run your program. Even then, if windows is shutting down processes in general, I'm not sure it will work. You could perhaps put the uninstaller in the runonce registry key, so it uninstalls on startup.

i tried to stop the form closing event also i that case it is giving me some error. which states the formate of the file is not correct i dont find any link between this error and my application. plz help me

sorry to say u this method has no effect on the shutdown procedure of windows
|
|
|
|

 Thought you were talking about app window
|
|
|
|

I'm curious, what is the reason for uninstalling your app when closing down. Seems a little drastic to me.

im not uninstalling the same application that im running im uninstalling any setup1 if previosly installed by me by mistake.

Have you stepped through the code ? Why on earth are you using the ArrayList class ? It's obsolete.

Well, I don't know. I am just wondering if you can explain what you've done to help yourself, using the debugger,etc. If you can tell us what line of code isn't doing what you expect, it would help us to narrow it down, without having actually build your code and run a client/server to see what happens.
Someone who has done more of this sort of work than me may come along and just answer it, but in the meantime, I think it's valuable to explore the things you should have mentioned in your original post, like what happens when you run it in the debugger.

Sir these what i have done
1. i made a dll remoting in which i had 2 methods AddClient and ALLClient
2. i made a server add reference of remoting.dll file and here i am calling the method allclient to view the clients connected to the server
3. i made a client add reference of remoting.dll file and here i am calling the method addclient.
>>> anything wrong ?

What makes you think that adding to the list in one program, will make it appear in the other one ?

You have two instances of the same class type. They are on different machines. They are not the same instance, nor can they be. Therefore, passing the value to one, does not pass it to the other. At least, that's how it looks to me.
