You may have more problems then you realize when
you put functions with CANCEL buttons inside of
other functions, but I guess you will discover that
soon enough. :-)

You might try moving to the directory you selected (not
possible with the way you are writing the code, but it
shouldn't be written that way anyhow, so...) and *then*
using FILE_SEARCH to look for the files. You can use the
CD command to change directories.

theDir = DIALOG_PICKFILE(/DIRECTORY)
IF theDir EQ "" THEN RETURN
CD, theDir, CURRENT=currentDir
theFiles = FILE_SEARCH('*.tif')
CD, currentDir

Cheers,
