I want to run ipconfig within my program and write the data to a file.
I tried the following codes but none of them worked.

ShellExecute(0, PChar('open'), PChar('ipconfig.exe'), PChar('/all > C:\output.tmp'), nil, SW_HIDE);

ShellExecute(0, PChar('open'), PChar('ipconfig.exe > c:\output.tmp'), PChar('/all'), nil, SW_HIDE);

If I run those commands in a DOS-Box they both work!
What am I doing wrong ??

Thanks in advance,
Tulip

I'm a bit confused everyone concerned... Does the /all flag really work? On my Win98 machine it doesn't, however the /batch filename command work fine..
And therefor the commandline parametr I'd use is similar to all above..
ShellExecute(Application.handle, 'open', 'ipconfig.exe', '/batch C:\output.tmp', nil, SW_Hide); - This works just fine, though I'm still puzzled regarding that /all flag...

good Luck

WinExec doesn't work, but Igor's example does !
This is strange.
Anyway, thanks to all of you.

Tulip,
I have NT too, there no "/batch" option in our case;).
I can explain why you sample didn't work, if you need.

Best regards,
Igor.

Tulip,

The problem is that "> redirection" is option for command.com, not for executable module. It come from MS-DOS. If you run your applicaton with command.com and look at parameters, you even don't see "> ...". And, of course, IPCONFIG can't process this option. I mean that redirection of output is command.com's deals.

The option "/C" is command.com option. It mean "carries out application, then stop".

My expression is analog of
C:> command /C ipconfig /all > C:\output.tmp

Best regards,
Igor.
