I created a Dos Command action to execute a batch file and it works fine if I don't have "log output" option checked.

If I check "log output" the command keeps "running" forever. &nbsp;When I click on "Stop" button, I get message:

"Program returned code &nbsp;: 1001"

&nbsp;

From the log created by batch file - it seems like batch finishes executing, but FinalBuilder does not detect it somehow.

When I run Batch file directly in Dos CMD&nbsp;it works fine.

&nbsp;

I also tried "Execute Program" action, but same issue.

This is in FinalBuilder 7.0

&nbsp;Hi,  
  
I encountered this problem a while ago, I guess it might has something to do with the pipe buffer deadlock.  
  
I resolved this with suppressing (actually, saving) the command line output to a file by adding "\>\> filename" such as:  
"dir /w \>\> logfile.txt"  
"olala.bat \>\> logfile.txt"  
&nbsp;

But this method won't show the log output (If I don't want it, I'd already unchecked log output),  
so I add a [run script] action and write a script to print the logfile line by line.  
&nbsp;

Hope this helps while they are checking for the problem.

Eric you haven’t really given us enough information to work with. What is the FinalBuilder build number, windows OS & version, and more importantly what does your batch file do? I would suggest you contact us via email support at finalbuild dot com with your batch file and finalbuilder project so that we can try to reproduce the problem here.
