Remove step icons from CVI Operator Interface to improve execution performance

[DaveMCG]

The CVI Operator Interface updates the icons for each step (lower right) when tracing is enabled. Can these be stopped but the steps still visable and would this improve execution performance.

Hi Dave,

I take it you are using the old style Teststand Operator Interface.

The only way would be to modify the code in the exedisp.c, in UpdateOnStepChange() function. Just comment out the SetCtrlBitmap() function there are two calls in this function.

As to whether it is going to make a noticable different in performance, well that depends on the spec of the controller (PC), graphics card etc. you are using. But you probably wouldn't notice any diference.

Before you make any changes, copy the sub-folders from the NI folder to the User folder and work from the User folder.
