converting OLE variants in a FileSystemObject script

[aartjan]

I am currently exploring the scripting power of labview and have some serious issues with converting a simple OLE variant to a LV datatype. I also tried with OpenG tools. Take a look at my example script
The ActiveX reference to FileSystemObject works with windows XP and maybe some older windows operating systems. Thanks

aartjan,

OpenG Data Tools are for LabVIEW Variant data only. AcviveX Variant is a totally different beast under the same clothes.

However, the solution to your problem is simple. The variant type VT_R8 tells that it is a 8 byte real value, e.g. a LabVIEW double. You simply use "Variant to Data" to convert it to a LabVIEW double. See the attached VI. Also notice the use of "Format into String" to generate the string, a node that is much more convenient to use than string concatenation.

thank you Jean-Pierre
I was trying to use the variant to data tool, but got stuck on the idea I had to feed it the right datatype. Thanks for the clear explanation and tips.
