CB_RESETCONTENT (Compact 2013)

  • Artigo

3/28/2014

This message is sent by an application to remove all items from the list box and edit control of a combo box.

Syntax

CB_RESETCONTENT wParam = 0; 
  lParam = 0;

Parameters

  • wParam
    Not used.
  • lParam
    Not used.

Return Value

This message always returns CB_OKAY.

Remarks

The Windows SDK documentation says this message always returns CB_OKAY (0). This is inaccurate. This message always returns TRUE.

If you create the combo box with an owner-drawn style but without the CBS_HASSTRINGS style, the owner of the combo box receives a WM_DELETEITEM message for each item in the combo box.
