System Tray Icon with background processes [modified]

[synunn]

Hi kids :) Background I'm writing a system service style application. It consists of a NotifyIcon in the sys'tray that has several functions that are called from the ContextMenu/Events. When the app' starts it should do nothing but sit there until the 'Start Sending' MenuItem's Event is called. This event starts a new Thread which checks a file repository between Thread.Sleep(15*60*1000). Problem To cut to the chase, the application is maxing out the cpu usage during a loop: while(this.Created){ Application.DoEvents();} How to I prevent this excesive usage? Do I need to access the System Idle Process? This usage doesn't actually halt the server or even slow it down it just capitalizes the usage as there is no other contender for the cpu's attention. I have tried to drop the Thread.Priority to BelowNormal but the applications Thread remains at Normal in Task Manager. -- modified at 5:41 Wednesday 5th July, 2006

Just make it sleep between the times it handles the messages: while (this.Created) { Application.DoEvents(); Thread.Sleep(100); } --- b { font-weight: normal; }

I thought that too but it causes a crash, The problem is that Events don't stack up between each Sleep so you have to click during the split second that Application.DoEvents(); is running :omg: -- modified at 12:34 Thursday 6th July, 2006 Not to worry though, I found a solution

Yes, the messages are queued. If the program crashes, there is something else that causes that. --- b { font-weight: normal; }
