void AFXAPI DDX_CBStringExact( CDataExchange* pDX, int nIDC, CString& 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 combo 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
The DDX_CBStringExact function manages the transfer of CString data between the edit control of a combo box control in a dialog box, form view, or control view object and a CString data member of the dialog box, form view, or control view object.
When DDX_CBStringExact is called, value is set to the current combo box selection. If no item is selected, value is set to a string of zero length.
Note If the combo box is a drop-down list box, the value exchanged is limited to 255 characters.
