I am trying to debug a problem where users occasionally have locked files which they try to open. The code appears to have correct exception handling but users are still reporting seeing error messages. How can I simulate a locked file so that I can debug this myself?
EDIT: For Windows.

Right-click on the file. In the menu that appears, select Lock File. To unlock, right-click the file and select Unlock File.
As you said, notepad cannot lock it exclusively. Luckily, declaring a streamreader locks a file exclusively unless you specify otherwise.
try this:
( >&2 pause ) >> yourfile.txt
>> opens yourfile.txt in append mode
see this for a reference
