Cannot resize the front panel when fp is closed/hidden

[ummagumma]

I am attempting to resize the front panel of a VI before opening it.

When front panel is set to load on being called, this is how I resize:
Open App Ref
Read FP.WinBounds
Modify WinBounds
{bottom = top + new_vertical_size
{right = left + new_horizontal_size
Save FP.WinBounds

When front panel is not set to load I can resize like this:
Open App Ref
Set FP.Open = True
Read FP.WinBounds
Modify WinBounds
Save FP.WinBounds

What I would LIKE to do:
Open App Ref
Set FP.Open = False (or disable automatic fp load)
Read FP.WinBounds
Modify WinBounds
Save FP.WinBounds
Set FP.Open = True

However this last series of commands doesn't work... I just get the FP completely unchanged/not resized as I wou
ld if I were to resize it with the front panel open.

Is it possible to set the origin / window size (WinBounds) before I open the front panel? Opening then resizing means the front panel objects are visible briefly before the panel is sized/oriented correctly--is there a way to set the default start up state of the VI programatically so the user won't see what's on the fp?

Have you tried to use the defer panel update property. Use a VI reference to a front panel property. This outputs a reference tha can be sent to a second property set to defer panel updates. This properly enables/disables the updated of the image of LV VIs on the front panel. You might try disabling the update then open/modify/set then reenabling the update.
