I need to know to turn off a combobox, and a trackBar! I explain, when you select an item from a combobox, I would like to disable another combobox and a trackbar in the same form ... Who can help me?:S
First you want to component to hide when something else happens right? Then here's what you do:
Click on the component you want and on the properties slab (press F4) click on the Lightning Bolt (4th icon from the right).
There you will see a big list of events, just choose the one that fits best for your situation and then press enter or double click it to be taken to the programming part of that particular event. Everything your program here will happen ONLY when your event takes place.
Then it's just a matter of programming the .enabled part of the control to activate / deactivate or the .visible to show / hide it.
