extract variant data type for case selection

[jyang72211]

I dont' know much about variant, so I am going to ask as many questions as possible on this topic.  If I have an array of variants, and each of these variant was converted from different data type.  This array will be index to a for loop and each element will be processed in a case structure inside the for loop. 

The question is I would like to take the data type from the variant, convert it into enum, and use it to select case on the case structure.  How do I do that?  Or what's the best way to do that?

"Get TDEnum From Data" VI from the Data Tools package.

There's also the "GetTypeInfo" VI that's in the <labview>\vi.lib\Utility\VariantDataType folder.

This is so amazing that it makes me want to cry!!  This is exactly what I want.  There are so many functions available.  I need to explore the website that you sent me.  Thank you so much.

check out also VI package manager. It allows easy install of many openg packages.

I have used the write to ini file, from the openg package, that writes a variant to an ini file.

Should have all the code you need.
