I am using labVIEW 7.0. If you will open the example " Temperature system demo.vi" in the example finder :mansad:then you will see that the different controls are grouped together, click on the block "system controls" and you will find that controls for Acquisition,Update period & Analysis have been grouped together so if you resize the size of this block all of them resize accordingly and if you try to move it all three will be selected and move together. Please tell me how it can be done.
