How do I modify the test of an enumeration programmatically?

[JasonWB]

Hi everyone,

I have an application with 8 scopes on it and the data displayed on the scope is selected by a drop down menu which is an enum control that is a typedef.  Since this application interfaces with different hardware, I need to be able to change the text in the menus (that is, the data items being displayed) programattically.  How can I do this?  I don't necessarily need to change the basic enumeration data typedef, but I do need to be able to change the text items within the instance, and I need to be able to do so by index - that is, if there are 10 items in the typedef enum, I need to be able to modify the 3rd one, for example.  Also, I may need to add some or remove some.  Any ideas?

Thanks,

Jason

You can't change the values of an enum while the VI is running or waiting to run, so if that's what you want, you should probably use a ring instead of an enum. Then you can use the Strings[] property to extract the array, replace the nth element and rewrite the property.
