Hello,

I want to save in a csliderctrl a extended GetPos. This GetPosEx() will return the real position inside a trackbar of a CSliderCtrl.  To Set this I want to do this inside the OnLButtonClick where I have only the position of the mouselick. How to calculate the real position/value of the slider at this position. My Slider has 0-100 value.

Hello,

I'm not sure I got everything.
You wan't to calucalte the position of your silder from the absolut mouse position?

OK.
You got the mouse position
You need the top left position from your slider using GetWindowPos
You need the size from your slider using GetWindowPos
I'm not sure how to get the size of the knobs left and right. I'll use them as consts and get the size by a screenshot.

pos = mouse pox X * ((right - left - (2 * knob)) / 100)

The specific answer depends on how you obtain the position of the mouse pointer.  The calculations will be different depending on if the location is expressed in screen-global or client-local coordinates.
