Sent by a bedit or hedit control to its parent window just before the control puts up any kind of dialog, including the lens, edit text, or garbage-detection dialogs.

The control's parent window receives this notification message through a WM_COMMAND message.



Specifies the identifier of the hedit or bedit control.


Specifies the handle of the hedit or bedit control in the low-order word and the HN_BEGINDIALOG notification message in the high-order word.

Return Value

If the parent window returns TRUE to this notification message, the bedit or hedit control refrains from opening the dialog; otherwise, the dialog is opened. Note that the application can disable the hedit or bedit control's ability to open a dialog by specificying CIH_NOEDITTEXT in the WM_CTLINIT message.
