How do you make an ActiveX server VI the active window?

[Leslie Brooks]

I am working with LabView 5.1 and Windows (NT and 2000). My VI is
compiled as an ActiveX server, and I am successfully calling it.
However, there does not appear to be any LabView method for traversing
the VI's menus, so I have to send keystrokes (via the Windows
Scripting Host) to do that. Windows Scripting Host will only send
keystrokes to the currently active window - so if the VI has been
minimized, I must first make it active. How do I do that?

If I have Notepad running but minimized, I can make it the active
window and send it keystrokes like this:

$WShell AppActivate "Untitled - Notepad" ; Activates but stays
iconized
(wait one second)
$WShell SendKeys "% r" ; Restores (open
s) the
window
(wait one second)
$WShell SendKeys "Hello World"

but this doesn't work with my VI. The VI window appears, but the
menu-activation keystrokes don't do anything. They worked just after
the VI was started (before it was minimized). How do I correctly
re-activate the VI so I can send it keystrokes?

TIA.

Before continuing on this thread, can you tell which VI menu you are trying to trigger? Many menu functions are also available programmatically so there might be a less involved way to achieve your goal...

you might wana try Windows API functions to activate or maximize the VI window. Here is the link to labview VIs that lets you call WinAPI functions.

BTW does the window even activate when you try to execute the script host method? Try changing window title to less than 8 characters without spaces....(just a shot).

Hope this would help
