Hello,
Obviously something has changed (and as I think
resulting in a bug) with the handling of refnums when updating LV form 8.2 to 8.5:
As I found out using probes, my calling vi starting an
instance of a template vi with “FP.Open” is reporting a certain refnum (e.g.
0xE1800013), the called vi itself reports another one about itself (e.g. 0xE1900011), and none of them is recognized by
the property node FP.IsFrontmost. I used this feature successfully in LV 8.2 to
detect which of my image stack players is topmost (because one has clicked on
it), so it was possible to change its conversion policy from the main program.
I’m afraid that this feature is not used very often in
that way so nobody reported a similar problem in your forum. There should be some way to do this job, as
in commercially available image managing programs like Photoshop.
Can you understand my problem? I have already uploaded
an exe file build with LV
8.2 on ftp://ftp.ni.com/incoming using the
SRQ 629758 (because an upload via my WEB browser was refused by your
server) which shows how it was working before, together with a reduced version
of the „source code“.
After
starting the program Easytrack:
1. Resolution > OK
2. Stack > Load > Test.stk
> OK
3. Stack > Display
4. a Player (Nr.0) appears
Repeat Step 3.
several times.
You will be able to change the brightness in each
player after having clicked on it using the „Display“ panel at the main
program.
I hope that you can help me, we need it very urgently.
Many thanks in advance.
