• Visual C++ notification message from CSliderCtrl when starting to drag

  Hi all, in my application, I have a CSliderCtrl and also one timer. at the timer event, I read the values from an instrument, and refresh the interface, also the CSliderCtrl. For some users, the interval of the timer is too short to change the value before it is refreshed.

I did not find any NM_LBUTTONDOWN or so notification. can anybody tell me the correct message to process . thanks, Hardik ...Show All
