Set the range of values for a slider control control

<span style= "White-space:pre" ></span>int m_stransvalue; CSliderCtrl m_ctrltransparency;

Where M_stransvalue is the variable associated with the Slider control control

M_ctrltransparency as a slider control control variable

To set the scope of a control in OnInitDialog ():

<span style= "White-space:pre" ></span>//set the range of the slider control HWND HSlider = (hwnd) m_ctrltransparency;::sendmessage (HSlider, Tbm_setrange, 1, Makelong (0,255));

Makelong (A, B) indicates the scope of the control

Note UpdateData () is required when m_stransvalue or assigning a variable to a control association.

Add:

SendMessage (HSlider, Tbm_setpos, 1, 10);

you can set the default value for the control, where 10 refers to setting the default value

Try:

1. The maximum and minimum values are also set for the Control association variable M_stransvalue

2. Set the maximum and minimum values by SetScrollRange ()

But the discovery is ineffective.
