I am looking for a way to open a file using the associated Windows application, i.e. if the file is a *.pdf file use Acrobat reader, iif it is a *.txt file using notepad.exe or whatever application is associated to that file type. If this isn't possible with Labwindows then how would I go about launching an external application without hardwiring in the exact location of said application, i.e. launch Adobe Reader without hard coding in the path to the current version that is installed.
