IMAQdx Open Camera.vi very slow

Doc,

 

This is correct and expected behavior. LabVIEW will search the system path for DLLs and find it. If it cannot find the DLL, it would not load.

 

Again, I'd need to see some simple VI that can reproduce this.

I am re-installing ni-imaqdx... the behavior is too strange. Even if I just make open - close example, sometimes it is fast, sometimes very slow.

 

I will then open the "grab" example from labview, then will open my project, then will save it and check if it solved the problem. 

 

If I still the same after re-installation, I will tell you

Hi Eric,

 

I re-installed all vision components and the same problem still occurs .... but I found why. 

 

 

 

If I put the "IMAQdx Open Camera.vi" in a timed loop with a priority not set to -1, then the time to open the camera is 25 seconds. Check the attached vi to see what I mean

 

I don't know why... I will leave the priority to -1...

Hi Eric,

 

 

 

I also noticed that the same applies if the VI priority is set above normal priority.
