How to pass data to a remote exe?

[Gak]

Hi every1,

We are doing an application in which we are using 4 PC's. I have a panel(Hardware) connected to one PC. I want to pass my data from hardware to remote PC. I am using "Open Application Ref"  for this. It is working fine. But when I am making an exe it is giving me error.

I have mentioned "Exported vis" & " Machine Access list" in option field.

Can you tell me how I can do this.

Please find Jpeg of my vi. It shows how I am sending data through vi now.

Thank you

You could also use network queues. These are an extension of standard LabVIEW queues that will work over the network. I would use something other than directly accessing the front panel controls. This is not a very generalized solution especially given that it will be run across the network and with multiple exe's. You can't open references to a control in a separate exe since each will be running in it's own data space. A solution like the network queue or a simple TCP/IP protocol will be more flexible.

If you get an error in "Open VI Reference" try wiring the VI name as a string. The VI should already be in memory since the application is running.

If you get an error at "Open Application Ref" make sure you're using the correct port (specified in the ini file of the application) and this port is not in use by LabVIEW (main instance or project).

But I agree with Mark that there might be better solutions than VI server.

Hi, thank you for reply.

The path is right as i mentioned Vi is working fine. but if i run exe "Open Vi Ref" gives out error.

I am not able to set  connection

I had build that application with TCP IP only. But most of the time it was giving me error as it imposes sequence..that a particular application must run first. I think it is my coding problem...so i turned to open application ref.

Can you tell me solution of this?

If you're talking to a compiled application the VI you're calling will be part of the exe, so the path you use in the screenshot can't be right.

Hi dan_u ,

I know the path in the code should not be used in exe. I have created exe on remote panel where i want to send data. and the code i have posted is on the machine where my panel is connected.But its not even error of path. "Open appliction ref" is not able to set connection with remote PC where my exe is running.

Can you post the ini file of the application you're trying to connect to?

[Gak]

I have not created any ini file...which file you are talking about?

And now  i am not in the office...its 10.21 pm here...

Tell me which file you want i will post it here tomorrow.
