instead of using window.Show() use window.ShowDialog()

ok, so what if you make a function in your control, let's call it SaveStructure() In your mainform/mainwindows/mainapplication you add this code to FormClosing event: MyFancyInstanceOfMyObject.SaveStructure(); done ... To be honest I don't know(I don't think there is an UnLoad event for user-controls by standard). But this should work anyway...

Thanks for your answer, I implemented it using MemberwiseClone() easiest right now and I think it will do. But if for some reason any of you have got a nice way to show ... please feel free to do so.

what do you mean by validating the path of a file? Check if it contains "valid" characters? use regexp. If you wan't to check if the folder specified exist use: System.IO.Directory.Exists(folder) If you wan't to check if the file exists use: System.IO.File.Exists(file) You will have to explain a little bit more for me what you mean by your first question. Every form has a FormClosing event, maybe you could use it to trigger other events/methods to do your work...

Hi! Recently I have bumped into a problem which I never have had before. I've got an object which have a couple of onChange events, I am doing some clones of this object and I really need to "copy" the events that the original object had into the new ones. Anyone who can help me Thanks // Daniel

check out www.mathschallenge.net register free for "project euler" lots of good programming problems. Best regards // Daniel Persson

Have you tried: A aObj = new A(); if(aObj is B) //do something

Thanks for your answers, I am about to implement this behaviour with an ownerdrawn component, built upon one "bar" class, and one "container" class. I am just asking to see if you know of, or ever have seen a component with these capabilities (or atleast somewhat close to these capabilities) or if you have any suggestions on how to build this component. I am NOT going to use labels. Also, the bars have to be containers for other objects which can be retrieved by clicking and so on...(this ain´t a problem though)

Is there some one here who knows of a component that works like the score in cubase. Let me explain: I want the capability to add and remove "boxes" boxes which should be possible to drag against a "timeline" please look at this simple picture for explanation: http://img140.imageshack.us/img140/6339/example8rm.jpg[^]
