View 2 RepliesThis class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

View 4 RepliesI'm developing an adding for office powerpoint application.I'm trying to display a description of the object(Customized object) currently dropped on the powerpoint slide in design mode(Design mode of the powerpoint).When i click on my addin the related object description will be displayed on a tabbed window as the first tabpage.
There is a button on the tab page, and when i click on it i need the description to get copied to windows clipboard.I tried this using clipboardclass it throws the following exception, System.Threading.ThreadstateException {"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it."}
Code for clipboard:
Clipboard.Clear()
Clipboard.SetText(lblObjectID.Text)
I searched the net for a solution and got couple of answers like, Put [STAThread] in the main function Thread.CurrentThread.SetApartmentState(ApartmentState.STA) Immediately before your call to SetDataObject.
But I'm not sure where to put the 1st one and the 2nd option didn't work.
I have used system.timers.timer to watch several folders and move files in my windows service. But the timer event stops now and then. I have read that it is better to use system.threading.timer in services.This is my system.timers.timer

AddHandler Timer.Elapsed, New System.Timers.ElapsedEventHandler(AddressOf Me.Timer_Elapsed)
Timer.Interval = 4000
Timer.Start()

How do this code look like in system.threading.timer?How do i start and stop the timer using threading? That is very important because i stop the timer when it comes to the elapsed event and when the code har run it starts the timer again!

I'm just looking for other people's thoughts and opinions on the way I have done something.I have a console application which needs to connect to various computers and reset the local admin password on each one. I got it all working but then decided that as there are a lot of PCs, it would be a good idea to use the thread pool to do a few at the same time.The problem is, I need this program to be run without any human interaction - so I cant just use ThreadPool.QueueUserWorkItem and pass it all of the computers to connect to, because then the program would exit after it had called QueueUserWorkItem for each one because there is nothing left for it to do. I cant stick a Console.ReadLine in there because like I said, it needs to be run automatically without anyone typing anything.
