Hello Forget the crap I said in my last post. I told you my mind was crashed back then. Anyway, here is the right thing. Two Approaches: Note: x is your object 1- Use the lock statement: lock(x) { DoSomething(); } 2- Use the System.Object obj = (System.Object)x; System.Threading.Monitor.Enter(obj); try { DoSomething(); } finally { System.Threading.Monitor.Exit(obj); } The above codes are quoted from MSDN. I think you already got that by now, but I want to post that just in case you didn't. Regards:rose:

If you have Microsoft Visio, you can create UML diagrams.

I'm no C# expert, but if the ieee488_send method is expecting a pointer for the second and last arguments, then I think you need to declare them BOTH using "ref" (as you did the last one). [DllImport("IIEEE_32M")] public extern static int send(int address,ref string strCommand,int xx, ref int status); send(inGpibAddress, Command, 0, inStatus); Also, does the method expect 3 or 4 arguments? In your VC++ example you have 4 arguments in the header file definition for ieee488_send. In C# you are only defining it as having 3 arguments... ---------- There go my people.

i don't know hoe to display the ellipsis button u can surely show the String collection editor, for this u can create a form with the FormBorderStyle = none and put a Richtextbox on that form and then set the items property by reading each line of the Richtextbox. Regards, Pramod

Use nullptr in lieu of NULL for managed objects.

Create your own button control, inheriting from the original Button class. Override the drawing code and supply your own to draw the correct image you want. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome
