Why does my GUI get truncated?

[GUI Guy]

My Labwindows/CVI app builds a GUI for a large test system that has 256 channels. Each channel has it's own panel. Problem is the last dozen or so panels are not displayed unless I delete some from the list. It seems that some display or other limit is being exceeded. Anyone know of a panel number/size limit in CVI? I tried increasing "Interactive Window Memory Size" to no avail.

Hello GUI guy,

I was able to create, load and display 256 panels on the UIR without any problems. I would suggest that if you no longer need a panel, to call DiscardPanel() to free up resources.

Do you see the same issue when you create a release executable?

Thanks.

Hi Wendy,

Thank you for the reply.

The problem occurs when the 256 panels are "expanded out". This makes them 3 times the size and I think the total size is the issue. These "channel" panels are laid on top of a main panel and a right-hand scroll bar is used to navigate through the list.

Hello Alex,

Would it be possible for you to post an example program demonstrating the behavior so we could reproduce it onsite?

Thanks in advance.
