I don't know how to get it to a variable, but you can use the ShellExecute API
to get the output into a file like so:
Code: Select all
; This example takes the outout of the "dir" command and puts it in a file.
dir$="c:\" ; Folder to examine with the "dir" command.
cmd$=Space(255) : GetEnvironmentVariable_("comspec",cmd$,255) ; Gets "command.com" (Win9x/ME) or "cmd.exe" (Win2K/XP).
ShellExecute_(0,"open",cmd$,"/c dir "+Chr(34)+dir$+"*.*"+Chr(34)+" > "+Chr(34)+dir$+"Output.txt"+Chr(34),dir$,0)

Hi all,
PB your code works fine but on my experience, you may need a delay after shellexecute_ (even short like delay(50) on my PC) otherwise file will not exist when processing result.
This is an issue which makes I prefer to use runprogram with the wait for closing flag (set flag to 1 or 1 | 2) to call external programs. The problem is that in some cases redirect is not easy with runprogram because the calling arguments method.
Using runprogram makes necessary to check how calling parameters are to be sent : sometimes in the filename parameter, sometimes in the args parameter (means runprogram("prog args", "", flag) or runprogram("prog", "args", flag).
I experienced both cases according to different external programs.

I normally check for the existence of the file after using ShellExecute, like so:
Repeat : Sleep_(1) : Until FileSize(dir$+"Output.txt")-1
That way, I know the file is ready for reading and I don't need to use RunProgram,
which lacks several of the needed ShellExecute parameters.

Hi WolfgangS,
Maybe you could try the Execute() function from the external CGI library, available at Paul's site:
http://www.reelmediaproductions.com/pb
It uses the CreateProcess API function to allow IO redirecting. In other aspects, it works like RunProgram().
Hope it helps, bye,
