Total Access Components Tour: Slider

The Slider control is a databound control that is used to adjust a numeric value by dragging or sliding the control’s tab or handle. It is commonly used in Windows Applications to adjust a continuous numeric value smoothly. The Slider control can be associated with another control to adjust that control’s value, or it can be used by itself as a vehicle for input.

Using the Slider control

There are three basic steps for using the Slider control:

Step 1: Associate the Slider control with another control

If you want the slider to adjust the value in another control, determine which control on the form to use. Otherwise, the slider can be used by itself to update a field or a value used in a subroutine.

Step 2: Modify the Slider control’s properties

Open the Slider control’s property sheet by right-clicking on the control, selecting FMS Slider Control 2002 Object, and choosing Properties. The Min and Max properties should always be set to the lower and upper limits of the input required. The control’s Value property is used to set its initial value. The LargeChange and SmallChange properties can be used to increment a value by the amount entered in either property as the Slider control is adjusted.

Step 3: Write code for changes to the Slider control’s value

In the Slider control’s OnChange event, write code to apply the user's changes. This can change the associated text box or other control’s value by applying the Slider control’s Value property, or by adding/subtracting the Slider control’s LargeChange or SmallChange values to the value in the associated control.
