Drawing on top of everything

[eissug]

I would like to draw a semi transparent circle on to of everything in Windows using LabView.  Does anyone know how I could do this?  Make a window with some kind of circular mask, make it transparent and always on top, and move it around ?

I can use windows messages.  Any ideas would be a huge help.  This is to indicate eye fixation for a quadcopter project for disabled people, specifically my dad.  For more info, look here:  http://www.rcgroups.com/forums/showthread.php?t=2284163

Hi eissug,

to get an idea what is possible you can start using this community example!

That sounds like a bit of a challenge.  If you're looking for control for a quadcopter, you might find this interesting: https://labviewhacker.com/doku.php?id=libraries:lvh_ardrone:lvh_ardrone

Thank you!  Sometimes it all depends on the right search terms!  I also managed to find two other resources right before going to sleep.

The second link includes an example of a clock that can be moved around the screen.  Just delete all of the clock code, the face, and set its transparecy...done!  : )

I will look into the example you gave and see if it works better for me.

It has been hard, but at this point I'm stuck with what I have.  If this project is successful, maybe I can justify further "research".  🙂
