Run with STDERR_CHILD and STDOUT_CHILD fails.

5 posts in this topic

HI,

I'm running a simple "Run" script from windows that runs the dos "find" intrinsic.

$pid = Run(@Comspec & ' /k ' & $findCmd , "someStartupDirectory", @SW_SHOW, $STDERR_CHILD + $STDOUT_CHILD)

thIs fails with a windows error box: "Findi String (grep) Utility has encountered a problem and needs to close. blah blah".

If I Run

$pid = Run(@Comspec & ' /k ' & $findCmd , "someStartupDirectory", @SW_SHOW)

it runs, the output in the dos window is correct.

Anybody have a clue as to what's wrong? Because the short Run command works, I'm not suspicious of the $findCmd string nor of the startupDirectory.

For some reason the hook into stderr and stdout is failing (my guess).

I've gone a bit further.

I've changed $findCmd to run search.bat that turns echo on, echos the input, then runs dos "find".

search.bat

echo on

echo %1 %2 %3

find %1 %2 %3

Running this, I am getting stdout back from the child process (the echo output), but windows find is failing with the error window described above = no output from find.

I'll roll my own find in C/C++.

This may be trouble for others in the future.

It would be most helpful if the whole script was posted, plus the contents of the batch file. Otherwise we're taking shots in the dark, considering $findcmd has no information for us to look at. Also, we could probably suggest ways of doing whatever it is you're trying to do without ever calling up a run command by using internal AutoIt commands to do whatever it is.

RLL,

   Did you ever determine why using @STDOUT_CHILD within the Run command will not work ? I am having the same issues.

 

(yes, I l know its a 4 year old post, but Ive been searching for 2 days now)
