Hi Alexander,
Well now that you have seen all of the normal answers to this Q, let me bring up another.
Warning! This is not for the faint of heart!
Please see this thread for an exchange Jean-Pierre (I would have given him 5 stars if this was an answer) and I had about two years ago.
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=137&HOID=506500000005000000AF5E000...
In this exchange he suggests a technique that makes virtual controls a reality. This approach requires quite a bit of work to make it happen but it does work.
I have used variations on this technique ever since and my customers cannot tell the diffence between my virtual controls and LV native controls. I should say the is one big short comming with this approach, that being, the controls look so much like normal LV controls that you find yourself double-clicking on them!).
The technique is based on the fact that you can use an "invoke Node" to get the image of a control. This image can then be inserted into a picture control where ever it is needed. You then use events from the picture control to figure out which virtual device was clicked and then direct your execution as indicated.
I have also extended this idea a bit. Once a virtaul control has been clicked, the "prototype" of the control can be made visable and positioned over its image in the picture control and key focus assigned. The use then can play with the native LV control as they expect. When done changing the control, the prototype is again hidden and the new value is used to update the picture control.
Summarizing:
Yes it is possible to have an unlimited number of controls in LV,
But,
It is not a native functionality and you have to do alot of work to make it happen!
And finally let me quote someone "Be careful what you ask for, you just might get it!"
It is truly amazing what you can do with LV if you really want!
