Hi @

I've taken your VI and modified it to use an event structure such that when you press a "Delete/Disable" button, the last entry in the table is removed and the entry in the combo box is also removed to stop it be selected. I'm not sure if this is exactly what you want but it may give you some ideas.
Notice that a feedback node cannot be used in the event case so I use the current table state instead.

Good luck

Instead of using a combo box, using a text ring makes it much easier to disable items in the list. Here is a vi that will do what you want. Also you can delete the last element in the table and make it enabled in the text ring for selecting again.

woh!!! NeiR & tbob you two really save my life!!!

You two's VI really work great... i think from here i can solve that problem that bother me long time...... actually i just learn about labVIEW around one month only.. so there still got many functions i still don't know to use. Like event case, i still can't understand exactly about it function... and my country here is very hard to find those reference books...

so.... do you all know about the where can i got it?

One more question... is it combo box cannot be disable like text ring?

anyway thanks you two again... you two's VI really help me so much so much!!! ^_^

The examples are always a good place to start learning about a new function.
If on the menu bar you go to Help >> Find Examples... ,then click on the "Search" tab at the top and type in a keyword, for example "events". Click on the Search button and a list of examples will be displayed.

As tbob has said you can't disable separate items in a combo box, you can only add or remove them.
If you specifically want to disable them then a text box is the way to go.

Good luck

below is the VI after i modified from tbob's....

You can enable whatever has been disabled by wiring to the Disabled Items[] property node. If you previously had elements a,b,c disabled, and now you wish to enable a, just wire b,c to the Disabled Items[] property node. You need to add this to your Remove event. Look at my example again and you will see how it is done.
