Hello Every Body
How can I handle a system event that is not exposed by the SystemEvents class using c# ? I read somthing about "InvokeOnEventsThread" method in MSDN :
public static void InvokeOnEventsThread(Delegate method);
But I don't undrestand how I can use it.Please Help Me.
Thanx

What are you calling a "system event"? What "event" are you looking to a notification of?

Hi...
I want to handle system events such as mouse clicks,mouse move and any action that happens out side of my application(When my application is not focused.Such as clicks on desktop or on any other application). Like babylone dictionary and keyloggers.I read an article in code project about system hooks(Global System Hooks in .NET) But hooking is very heavy action.The CPU usage of this sample is 80% to 100% when application is running ! I want a way to trap this events when they happen.
Please Guide me !

The only way to grab the mouse and keyboard events are global system hooks. If written properly, the hooks will not consume any measurable CPU time for days, maybe even weeks. But, of course, this all depends on what your doing with the captured messages.

Hi folks,
I've written a custom installer / uninstaller for my application and everything works fine 
But...
How do i delete my uninstal.exe??
I can't tell it to delete itself but i have been told there is a way to get windows to delete a file next time it starts up. Anyone got any ideas on how to do this?

Very close but not quite.
Assume i have installed my application and there is a file called
c:\uninstall.exe
Uninstall.exe is registered with the windows add / remove programs.
The user tries to remove my application and all files and registry
entries are deleted without any problems. All except one, Uninstall.exe.
I can't tell it to delete itself as it is currently running and would
obviously crash.
Anyone know the answer or able to point me in the direction of an article?

I wasn't aware that i could put commands into the registry.
Could you show me how ot do it using the c:\Uninstall.exe as an example?
Thanks for your help

Colin pointed out the link to help. Here's the pertinent line:
The data value for a key is a command line.
Use a command line command, like "del", as in "del c:\uninstall.exe"
Remember good ol' DOS?

Marc,
Thanks for clearing that up, that's the "Idiot Proof" answer i was after but...
When i create my key with the value of del c:\uninstaller.exe i just get a message saying Cannot find del... when i restart my PC.
I assume i am missing something very trivial and i'll probably kick myself when i get it sorted but can you tell me what i'm doing wrong. Does the registry entry's name have to be anything specific? oir is that irrelevant in this case?
Cheers
Kev

Ew. I had assumed that it would be able to run DOS commands. You might need to do something like c:\uninstaller /u, where you pass a command line parameter to itself. BTW, it won't crash if you tell it to delete itself--why would it? The running version is in memory. There is the potential, though, of a locking issue--a running app might have its file locked by the OS, but I'm not sure.
Strange stuff!

Lol, after all that you are right, you can just tell it to delete itself!!
I just assumed there woudl be file locking issues but there's not.
Thanks to you all for your help.

Check out: Win32 Q&A (MSJ 01/1996)[^]. It's an older article but I think it's an interesting approach (at least if you're not afraid of P/Invoking  ). Now, I haven't checked out if you can use this technique in managed code, but if not you can at least create a helper executable to take care of the final deleting.
Best regards

use System.Timers.Timer
see here for example - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemtimerstimerclasstopic.asp

Look into the System.Threading namespace on msdn.
Simply create a thread and do something like
while (escape condition)
{
thread.Sleep(60000)
if (DateTime.Now.Minute == 15)
{
}
}
The thread.Sleep command simply stops the thread eating system resources by
making the thread wait for 60 seconds between checks.

Override the onDrawItem event:
protected override void OnDrawItem(System.Windows.Forms.DrawItemEventArgs e)
{
// Your menu drawing code
}
and set the OwnerDraw property of the menu items to "True"
