Demonstrates how to pause in VB, without winding up the CPU, as While/Doevents/Wend code will do.
Inputs
Milliseconds to pause
Assumes
This uses the timeout feature of the WaitForSingleObject API call to break up a pause into smaller millisecond time chunks, allowing for a more responsive pause function. It also eliminates the CPU usage issue when using While/Doevents/Wend loops that make it hard to catchs problems. Since it does not do a comparison to the system clock, it mearly counts up milliseconds, there are no issues with midnight or clocks. You can change the resolution to suit your system. I have not submitted in a long time, so let me know if you would like more like this.
