Question

Background: I have a post-build process that copies a file to another location. It looks like this:

copy $(TargetPath) "%programfiles%\mypath"

This step can fail if the another process is using the file. The step is not critical, so if possible I would like to ignore the failure. To do this I need the script to check to determine if the file is being used by another process.

Question: Is there a way of testing a file in a DOS script to determine if it is being used by another process?

Answer 1

Ok, so I needed to check the errorlevel after performing the copy, so that I could handle the exit properly. The solution is below:

copy $(TargetPath) "%programfiles%\mypath"
if errorlevel 1 goto BuildProcessFailed

goto BuildProcessOK
:BuildProcessFailed
echo BUILDPROCESS FAILED FOR PROJECT $(ProjectName)
goto ExitBuildProcess
:BuildProcessOK
echo BUILDPROCESS OK FOR PROJECT $(ProjectName)

:ExitBuildProcess
