LaunchExecutableEx LE_HIDE make visible

[ISITEC_RIEPER]

Hello,

i have written a program that starts different exe-files with the
LaunchExecutableEx function. The windowState is set to LE_HIDE.
Sometimes i need to make the window of the exe file visible. How can i make
the runnig program visible from within the program that started the exe
using LaunchExecutableEx , after it startet with the parameter LE_HIDE?

Thanks for any help

Hi Norbert,

my understanding of your issue is that you want to control the visibility of a stand-alone LabVIEW application with an external programm.

Controlling FP visibility within LabVIEW is fairly easy. Use a property node with FP:Transparency and set it to 100 for invisibility an 0 for full visibility.

You can communincate from external programs with your LabVIEW stand-alone application by several means. TCP communication is probably easy to establish. You could also use ActiveX.

Thanks Topp,

yes, i want to control the visibility of a stand-alone exe (CVI, not Lab
View) from an external program. I can start the exe with the
LaunchExecutableEx function so that the stand-alone exe is not visible on
startup. But i don't see how its possible to make the stand-alone visible
from within the starter program without any communication between the two
applications....
So i used shared memory to communicate between the two applications because
i don't see that i can show and hide a stand-alone exe from another
application without any communication 😞

Hi Norbert,

please take a look at the following documents:

BTW: Functions for controlling the window-behaviour will you find in the Win32-API.

I hope this will help you out.
