Answer» Here's my code below. I've setup the batch file to read the directories in a folder, and then list them in ALPHABETICAL order with a number beside it so the user can then choose which folder they want to use. The problem is that the counter (which numbers the folders) isn't progressing, and I can't figure out why! Is there something in the code I'm missing, or perhaps a global setting/variable that I don't have that I need? See red items :ListFolders SetLocal enabledelayedexpansion Set Input=0 Set Count=1 Set Folder=%1 Echo Choose a Folder from Below: For /F %%a in ('dir /b /o /a:d C:\MainFolder\%Folder%\*') Do ( Echo !Count! == %%a Set /a Count=!Count!+1 ) Set /P Input= Selection:Just out of CURIOSITY, what does that line do exactly? Quote from: Feidom on March 21, 2008, 03:35:29 PM Just out of curiosity, what does that line do exactly? Normally, in a WINDOWS NT family batch file, ordinary variables (the ones with percent signs like this: %variable%) are expanded just once, at run time. This includes variables inside loops. This means that a variable cannot be created or its value changed in a loop or a multiline IF STRUCTURE. To make that possible, Windows 2000 introduced a new feature - delayed expansion. To use this you need to do the following... 1. Enable delayed expansion by either (a) start a command shell using CMD /V:ON -- or -- (b) include the line setlocal enabledelayedexpansion in a batch file before using delayed expansion -- AND -- 2. Use exclamation marks (!) instead of percent signs (%) around variables as in my suggested code above. Type cmd /? at the prompt and/or Google for "delayed expansion" for more information, and very possibly a better explanation than I have given here. |
