How to send a command to an already open command window?

[kech]

Hi,

I experience the same error message when executing the (System Command (cmd.exe) test.vi)  but on a 32bit Win 7 Pro OS...

Err =  "The process tried to write to a nonexistent pipe".

Albeit the response to "dir\n" was displayed  in the data2 display.

I also tried to change the Write to Pipe string from "dir\n" to "ipconfig\n" - but here there was no response in the data2 display.

oglib_pipe-1.0-1 has been installed via VI Package Manager

I would greatly appreciate some assistance.

Cheers

KC

I realize this is a very old thread, but for anyone who wants to do this in the future, there is a .NET API for it that JKI has conveniently already wrapped for use in LabVIEW: https://www.vipm.io/package/jki_lib_dotnet_system_exec/
