ok got it ronen

Got it :) thanks all Ronen

Do any of the child forms have FormClosing(..) handlers? If so check them to see if they might be doing anything that's interfering, such as setting e.Cancel to true. You might also try stepping through the main form's closing handler with the debugger if you haven't done that already.

thank you very much for your input

you are correct by saying that the worker thread should be event-driven and should not poll... I have used the following example to learn from: Bounded Blocking Queue (One Lock)[^] and within your worker thread (it must be a thread that is started in the constructor) use: while (true) { lock (syncRoot) { //block the thread until there is a message in the queue while (iCount <= 0) Monitor.Wait(syncRoot); //there is work to do, lets dequeue and process it class\_Message MessageWorker = messageQueue.Dequeue(); iCount--; . . . this has worked out really well and eventhough it's a blocking queue it works nice and fast !

I see OK Thanks Ronen

This looks a little like a BitArray. You might take a look at the documentation MSDN[^], and see if it suits. Henry Minute Do not read medical books!

Add it as a linked resource to the dll which you are sending. In Visual studio you can easily add a linked resource by going to project properties / Resources button. Click on the top first dropsown button to change ti to files and then you can easily add. :) Shyam.. My Blog dotnetscoups.blogspot.com

The DataGridView will automatically show ALL public properties of your Node class. So you could do as musefan has suggested, or a possible alternative is to create a new class 'GriddableNode' which holds only the properties you wish to display, then create a list of some sort to use as the datasource for the DataGridView. OR you could edit the columns of the DataGridView, use the SmartTag for the gridview in the designer. Henry Minute If you open a can of worms, any viable solution *MUST* involve a larger can.

Thanks you all Ronen

got it thanks man Ronen

thanks Ronen

The tooltip you can assign in the properties of the control, same place as the event handler goes. But, you do have to do that for each menu item/button/etc. Same for the shortcut. Christian Graus Driven to the arms of OSX by Vista.
