Opening an Executable(exe) file created by LabVIEW on remote PC

[RTSLVU]

You need to refreash me a bit here but...

Are you trying to open a Labview exe from another Labview exe?

Have you tried the "System Exec.vi"

You will have to know the exact path to the exe you want to open but it should work.

I have used it many times to launch non-LV exe's and batch files.

Yes, I am trying to open LV exe from LV exe.

I have already tried sysexec.vi, but didn't succeed

If you are using it, please let me know the exact command you are using to open an exe on remote pc through sysexec.vi

Ok, I scanned all the old messages in this thread and found with this post,

Tried Everything in my mind, but could not run the exe remotely on XP. The only logic I want to implement is to run a LabVIEW exe on a remote PC directly through a LabVIEW exe from host. Is it not possible in XP?

And a few others that lead me to believe you want to:

1. Launch a LV program on the local computer
2. That program will launch another program on the remote computer

Right?

As far as I know there is no way to make Labview (or anything for that matter) just launch a program on a remote computer without something running on the remote that is waiting and willing to accept the remote connection.

I suggest you make a small "listener" program in LV that runs transparently, or runs in the background on the remote computer and just waits for the local computer to contact it. Then the listener can launch the main program on the remote computer when requested using any of the standard LV methods like the sysexec.vi.

The only caveat here is the listener must be always running on the remote computer. I suggest putting it in the start up group, and I think there was a  post here leading to instructions on on how to make a Labview program run in the background.

Posting in this thread after quite a long time, but I have come across this situation again. I am thinking on how to implement this without having a "listener" program running as a daemon VI on the remote PC. Is there any other way we could do this?

Simple answer, no.

Again you can not launch a program on a remote computer without a program already running on the remote computer waiting for the remote connection.

For example a remote desktop application, possibly a Telnet server (the Windows Telnet program is only a client), or a custom program.

Yesterday some of my colleagues were succesfully able to launch the LV exe on remote pc without DCOM or any other methods.......the application is showing up in the task manager of remote pc......but only its front panel is not shown......we are trying to figure out how to bring up the front panel on the remote pc.....(already used open FP property but aint working)

Sounds like it was launched as a service.  You can try editing the service to allow the program to interact with the desktop.

I would be interested to hear the steps they took to do this without any type of interaction on the remote PC.

Makes me wonder if they are exploiting security holes.

If not it raises security concerns because if you can write a LV program that can launch executables on a remote PC without user intervention then you can write a program to install and run things like key loggers, password sniffers, or other hack and spy type programs.
