Question about “SetWaitCursor(1);”

[chris_chua]

Hi

Currently I study the program below and have some question needed advice:

A) What is the reason  to need “SetWaitCursor(1);” on the below code?

B) Does it cause a run time delay on the whole program? 

C) can we remove " SetWaitCursor(1);” from the below code?

code

//daqmx configure code

SetWaitCursor(1);

DAQmxErrchk (DAQmcCreateTask("",&taskHandle));

DAQmxErrchk (DAQmxcreateDIChan........

1. Possibly the desire to let the user know about an operation that can take some time by changing the cursor shape to the hourglass
2. As any code it will take some microseconds to execute, if you call it a delay depends on your time scale 😉
3. Yes, you can safely omit the command - and the corresponding SetWaitCursor(0), too.

I am wondering if your questions have been answered...
