DDX_CBIndex

The DDX_CBIndex function manages the transfer of int data between a combo 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_CBIndex( 
   CDataExchange* pDX, 
   int nIDC, 
   int& index  
);

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 combo box control associated with the control property.

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

Remarks

When DDX_CBIndex is called, index is set to the index of the current combo box selection. If no item is selected, index is set to 0.
