DDX_Slider

  • Article

 

The DDX_Slider function manages the transfer of int data between a slider control in a dialog box or form view and an int data member of the dialog box or form view object.

Syntax

      void AFXAPI DDX_Slider(
   CDataExchange* pDX,
   int nIDC,
   int& value 
);

Parameters

  • pDX
    A pointer to a CDataExchange object. The framework supplies this object to establish the context of the data exchange, including its direction.

  • nIDC
    The resource ID of the slider control.

  • value
    A reference to the value to be exchanged. This parameter holds or sets the slider control's current position.

Remarks

When DDX_Slider is called, value is set to the current position of the control's thumb, or the value receives the position, depending on the direction of the exchange.
