How can I use the function OnHScroll() for a CSliderCtrl control?

[Johan Machielse]

Hello,

When I change the position of a slider I simultaneously want to update a
static control with the current position of the slider.
For that problem I will have to use the function OnHScroll, but it only
works for CScrollBar controls?
How can I solve this problem?

Thank you for solving my problem.

Johan,

I believe that the slider control sends WM_HSCROLL messages as well as
the scroll bars, so it should work.

What have you tried that didn't work?

Johan,

Although the parameter is defined that way, it's really just a CWnd
pointer.

Compare the window handle against that of your control. For example:

if ( GetDlgItem( IDC_SLIDER1 )->m_hWnd == pScrollBar->m_hWnd )
{
/* It's IDC_SLIDER1 */
