DDX_Check

The DDX_Check function manages the transfer of int data between a check box control in a dialog box, form view, or control view object and a int data member of the dialog box, form view, or control view object.

void AFXAPI DDX_Check( 
   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 check box control associated with the control property.

  • value
    A reference to a member variable of the dialog box, form view, or control view object with which data is exchanged.

Remarks

When DDX_Check is called, value is set to the current state of the check box control. For a list of the possible state values, see BM_GETCHECK in the Windows SDK*.*
