How to search a property value in a TDMS and return the group name.

[lowbat]

Hi.
Please help

I want to search a TDMS file by property value and then return the group names or channels.
I am using labview 8.2 with the connectivity toolkits.

Use FileIO->Storage API. Configure "Read Data" with your property name, wire value and comparison operator (if necessary), use "Get Properties" to get the group/channel name from the result refnum(s). Note that you need to search for channels and groups separately.

I try your sugestion but I get an error in the block diagram, I gues becouse I have already open the TDMS file. So I try again in a new VI and I was able to run it complete with no error but I get no display. Do I need to search and read for each specific group/channels?

What's the error number / message? Be aware that the second connection needs to be read-only if you already have a writable connection open.

The error # is -2558

I try to close the TDMS file before it reach the search part but still give me the error code -2558

Actually, you're not. There is no "Close Storage" Express VI. If you add that, your code should work.
