Hi, In a Mouse Down? on a tree, I need to know if the user clicked on a expand/contract symbol, because I need to discard clicking on items but I still need the expand/contract mechanism.

I have been trying to understand what's going on with my tree control and I'd like to share this with the community to see if somebody has seen this behavior before. Maybe there is something obvious that I am not seeing... I attached the VI (LV2011) with instructions inside (will take you 20s to perform the experiment, I dismantled the VI to its bare minimum). Please don't comment on the overall architecture (state machine...) since I modified the VI just for the sake of posting it here and removed all advanced features. Long story short, after programmatically modifying the value of t

I am writing a performance-sensitive application which requires the use of a nearest-neighbor lookup. Originally I used a brute-force method, but unfortunately this gets to be very slow as the data size increases . I have a point cloud of ~100k points in 2D, and need around 50k nearest neighbor lookups per second as a minimum performance requirement. As a solution I wrote a kd-tree in .Net and used LabView to call the .Net dll. However, I discovered that each .Net transaction carries with it about a 0.5ms delay. I've tried bunching the data up into groups, but this only helps so much, as I am
