Returning a value

OK, I may be showing up my lack of knowledge of command lines, but... can I only return to VB a boolean value?.

Coding in VB, with "-xmp-xmp:Label -b -k" I can see that exiftools is seeing the correct tag value "Yellow" in the command line window but all I seem to be able to return is a 1 or 0 value. Any thoughts/help?

       Set Wshshell = CreateObject("wscript.shell")

       retcode = Wshshell.Run(dngCommandLine, 1, True)

       Debug.Print retcode

The return code indicates only success or failure of the command.

What you need to do is capture the console output of the command
to return the value of a tag.  I don't know how to do this in VB, but
it is an easy thing to do in C or scripting language in Unix.

Also, you probably don't want to use the -k option here, because it waits
for keyboard input which doesn't make sense from within a VB script.

Thanks Phil, I'll follow that up. C? Eek, that's real programming isn't it?
