Hi,
there is no direct way.
Maybe possible, at least an interesting job, would be using some Win32
APIs. First you´need the Calendar´s window handle. With this you could
get its position and size. In this rectangle you can search pixel by
pixel for the color of selected rows. That´s the easy part of the job.
In addition you´d need an algorithm for getting the time. You could
store snaphots of each time, I mean e.g. the picture of 06:00, 07:00,
etc. But maybe there are better methods for recognizing pictures.
If you have e.g. the top position for a selected row then you could
"walk" left to the times and compare the pixels found there with your
stored snaphots.
Alternatively, of course, you could think about a re-design of your
solution. For humans it´s very easy to give you the needed data
