Get output from chcp command?

Recommended Posts

I have a script that tests the output of the windows chcp command in order to get the current code page (typically 437 or 850). I can make this work easily by redirecting chcp's output to a temporary file and then reading the file, but I can't get the output from StdoutRead. The following code works perfectly if I use the commands "ver" or "dir", but produces empty output from chcp. What am I doing wrong?

#include <AutoItConstants.au3>
$pid = Run(@ComSpec & " /c chcp",'',@SW_HIDE,$STDOUT_CHILD)
ConsoleWrite (Return_Output($pid) & @CRLF)

Func Return_Output($job)
  ProcessWaitClose ($job)
  Return StdoutRead ($job)
EndFunc

Thanks for any help with this slightly puzzling problem.

Replace your run statement with this one :

$pid = Run(@ComSpec & " /c chcp",'',@SW_HIDE, $STDIN_CHILD+$STDERR_MERGED)

Perfect! Thank you! I don't want to waste your time, but if you could explain how chcp differs from (for example) ver, I'd be grateful.

I am not exactly sure why some internal commands require to open both directions stream.  If you look at @error after StdoutRead, you will notice that there is an error (EOF probably).  Error handling can greatly help to find where the issue is located.

But why that particular command is different from others, Just know it from experience :unsure:

Simpler:

Local $s = RegRead("HKLM\SYSTEM\CurrentControlSet\Control\Nls\Codepage", "OEMCP")
ConsoleWrite($s & @LF)
