DDX_FieldCheck

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

void AFXAPI DDX_FieldCheck(
   CDataExchange* pDX,
   int nIDC,
   int& value,
   CRecordset* pRecordset 
);
void AFXAPI DDX_FieldCheck(
   CDataExchange* pDX,
   int nIDC,
   int& value,
   CDaoRecordset* pRecordset 
);

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.

  • pRecordset
    A pointer to the CRecordset or CDaoRecordset object with which data is exchanged.

Remarks

When DDX_FieldCheck is called, value is set to the current state of the check box control, or the control's state is set to value, depending on the direction of transfer.
