kill process vi

[Dermot1000]

Hallo,
I need a VI that kills a running process that does not have a window under windows 2000. I am using LabVIEW 6.i.
I tried to convert a VB code that works to LabVIEW but the program I generated crashes LabVIEW all the time at different places. I used the Kernel32.dll and Psapi.dll in that VI.
The Message says that an Area of memory could not be read. I am really interessted why that happened and why LabVIEW crashes, because I want to use Windows dlls in the future.
But first priority is to get a VI that terminates a running process. I would be very thankful for that.
Greetings Dermot
I appended my code. It is a bit chaotic - sorry. Did not have much time.

You can use the "kill" command with SystemExec. The command line should be "kill //f". The f option forces process termination. I have a vi that does this but it is in LV7.1.

I don't think "kill" is a standard command on Windows. If "kill" doesn't work, you can try "taskkill".

[LarsRoe]

The message "An area of memory could not be 'read'" is common and there are lots of reasons why it could be failing. Calling external code is advanced, and if it is not configured exactly correct, it can crash. Be sure that you are using the correct calling convention and the arguments are exactly the same.

I am using Windows2000, and kill is a standard command. Open up a command prompt window then type kill /?. This should display the help file for the kill command. If you get command not found error, then it is not a valid command.

I have XP. Maybe it changed.

I'm using w2k, and both taskkill and kill are no known commands....

Why does kill work on my Win2K machine? I can open up a command window and type kill id# and it works. I also have a vi that passes the kill command to system exec and it works also.

Dermot,

Try it like this. I couldn't figure out exactly what was wrong, so I rewrote
the vi...

Be carefull with the input name. If you just type "a", all processes with a
"a" anywhere in any of the module paths are killed. Also, be aware that the
"\" has a different meaning in the match pattern function.

Regards,

Wiebe.

Thank you for the reply, but I can't open the vi because I only have LabVIEW 6.0. Can you save the VI for 6.0 and repost it?
