Hi all, I am completely new to Labview Object-Oriented Programming, and I have a problem about make a choice between using classes (or LVOOP) or not, to solve my problem. If you take a quick look my previous question at this link: http://forums.ni.com...1852395#M630661 you can find my VIs and help me to choosing the right way. To summarize, I try to write a program which will used for "Palletizing Machine". In my VI, there are "Boxes" that are held with a mouse click to drag operation and released with the mouse to drop operation and a "Pallet " (boxes are placed on this pallet) and some buttons. I have a problem with number of boxes which will use Palletizing. If i want to placed 100 Boxes on a pallet, i must add the nearly same "mouse up, mouse down and mouse move cases" and it is a long way to hoe and wasting time and increasing the size of VI. So please check the my questions at link above, and help me which way should I choose? Or just say should I use the LVOOP for box generator, because according to your answer and suggestions I will start to learn LVOOP or try something else (like picture controls). Best regards. drycsr

Thanks for your help Ton.

hi, i want to move objects to a pane by using mouse (drag and drop to pane). there are more than one objects (as box). how to make when an object (box #1) which is clicked by mouse is active, the other objects are passive? So , when i rotate the box #1, the others (box #2, #3,...etc.) are not affected?

in the attached picture, button #1 is on the stop button and under the array. how to fix this error? the block diagram is also added. and there are more than one buttons. how to make when a button (button #1) which is clicked by mouse is active, the other buttons are passive?
