I'm using Windows 2000 Advanced Server SP4 and I have tried the code snippet below:
WindowsIdentity winid = WindowsIdentity.GetCurrent();
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsPrincipal prin = (WindowsPrincipal)Thread.CurrentPrincipal;
MessageBox.Show(prin.IsInRole(Environment.MachineName + @"\" + "test").ToString());
My computer is not a domain controller and I dont have active directory installed. I created a group on my local machine named 'test' and added administrator to that group as a member and logged on to windows with administrator account. So the code above returns True and displays it. This is fine but when I remove administator from the group 'test' the code still shows True. This persists until I delete the group itself. Then the code displays 'False'. What do you think is the cause of this behavior?
I also have a problem retrieving a specific user's groups. I thought the IdentityReferenceCollection class would be useful and I used the code below:
IdentityReferenceCollection irc = winid.Groups;
foreach (IdentityReference var in irc)
{
MessageBox.Show(var.Value);
}
But this only displays some numbers that might have meaning to windows itself. but not a visual appearance of the groups on my local machine. such as a string conataining the groups' names. Any idea?

I want to have a loop that checks if a key has been pressed during that time.
The loop has a delay of Time.Sleep(25);
So the loop starts, check if a key is down then continues with the code, the time delay hits then it repeats.
The problem is I can't use ReadKey Read or ReadLine because these all stop the "flow" of the code causing it to physically halt, I want to code(loop) to continue if a key is pressed or not.
And System.Windows.Forms; isnt an option as far as I know.
Thanks guys.

Hi
try using different thread in order to check if a key was pressed
for example
static void Main(string[] args)
{
object key = new object();
bool stopLoop = false;
Thread t1 = new Thread(delegate()
{
while (Console.ReadLine() != "Q") ;
lock (key)
{
stopLoop = true;
}
Console.WriteLine("Stop Command Issued");
});
t1.Start();
while (true)
{
lock(key)
{
if (stopLoop == true)
break;
}
}
}

Wow thanks!
This is great, but is there anyway to use
ConsoleKeyInfo
.key
ConsoleKey
etc instead?
Thanks in advance ^0^

Nevermind I figured it out on my own, all I had to do was change/add these two lines.
^O^. Thanks!
ConsoleKeyInfo keyInput = new ConsoleKeyInfo();
while (Console.ReadKey().Key != ConsoleKey.Escape) ;

Ran into a slight problem.
This performs actions within the while without stopping to check for the key but how do you add additional keys?
So the loop goes constantly checking for an escape key press, and if it happens it breaks the loop.
but what if I want it to perform actions based on other keys while its looping?
If you got any info that would be great. =O)

Don't worry again I think I cracked it.

If anyone is interested in how this is done. I basically modified it so that it reads the key in the thread inside the loop over and over, and it does things according to whatever the key is. This is just an example.
static void Main(string[] args)
{
object key = new object();
bool stopLoop = false;
ConsoleKeyInfo keyInput = new ConsoleKeyInfo();
Thread t1 = new Thread(delegate()
{
while (keyInput.Key != ConsoleKey.Escape) // repeats the below code until...
{
keyInput = Console.ReadKey(); // Constantly checks for pressed key
if (keyInput.Key == ConsoleKey.UpArrow) // does things depending on key
{
Console.WriteLine("Up Arrow");
}
if (keyInput.Key == ConsoleKey.Escape) // the loop break
{
lock (key)
{
stopLoop = true;
}
}
}
});
t1.Start();
while (true)
{
Thread.Sleep(200); // Putting a delay in so it doesnt run at a billion mph
Console.Write("01"); // Writing numbers just to visually check the speed
lock (key) // This stops the loop if Escape is pressed as defined above.
{
if (stopLoop == true)
break;
}
}
}
}
}

Hello everybody!
My team and I is facing a big problem write now, and after two days of searching and testing we didn't succeed!
We have to close a Database File (SQLite) on our local machine, which was opend from our process.
This is kind of a workaround, because the Database crashes thanks to a bug in SQLite, and after that the file is locked!
What we found out is that it would be much more simple, if we wanted to close a locked file from across network shared computer.
Like this[^] very nice post, from Heath Steward shows.
In this case we could use netapi32.dll methods.
Maybe someone can point us the write direction.

As a workaround we now start a freeware program "unlocker" which works.
But this is the soulution we do not prefere (Which is all said by "workaround")!
Thanks for your time!
All the best,
Martin

When i run may application,
My applicaton should find the password field in the internet explorer and edit that control using user32.dll.
for example, in yahoo login page when i press the hot key then i want to find the username and password field and edit it using user32.dll.

Hi,
I have created a sample Windows Service, in which I want to provide a notify icon on the system tray.
I have placed a notify icon and a contextmenustrip on the Service's Designer form, and on the OnStart() method of the Service I have assigned a value to the contextmenustrip property of the notifyicon. The following code snippet is written on the OnStart() event of the service,
contextMenuStrip1.Items.Add("Login");
contextMenuStrip1.Items.Add("ViewRecentDocuments");
notifyIcon1.ContextMenuStrip = contextMenuStrip1;
notifyIcon1.Text = "Notifier";
notifyIcon1.Visible = true;
After that I have installed the Service in the system, and started the service. The notifyicon get displayed, but while right-clicking on it, contextmenu didnt displayed.
Is my code is correct one, if not what change should I do, to make the contextmenu to be displayed on notifyicon's right-click event..
Anyone knows the solution, please reply me.
Thankfully,
jm

You can make a server application within the service...use dotnet remoting

If the windows application is on the same PC as the service best is to use .NET Remoting with IPC protocol. Registering a IPC port will not make the firewall jump and you can use binary serialization.

I am just wondering why you need to take a long route..If the need is to run sone function and get a value back why dont you define OnCustomCommand and pass a value.You have the room to pass between 128 - 256 this you can execute up to 128 custom functions in side the service.
|
|
|
|
|
Because i can't find a any way to get back any values from service application. OnCustomCommand is void and i can't use 'return obj' in OnCustomCommand method. If you know a good way for it, please write it to me.
Thanks.
