VBA ReadyState basics
 

I am new to VBA and am interested in ReadyState. I have gotten much of
my code to work through trial and error of different Do While and Do
Until readystate commands. All that I know about these is the basic
definitions. Is there a way to monitor a webpage's readystate and then
exploit that in code? Can you tell me anything about how Do While and
Do Until work?

Thanks!
