WM_CTLINIT
Sent to the
parent of a bedit, hedit, or iedit control while the control is being created
in order to get extra information about the control.
Parameters
wParam
Type of control.
This parameter can be CTLINIT_BEDIT, CTLINIT_IEDIT, or CTLINIT_HEDIT.
lParam
Address of a
control structure, depending on wParam. For values of CTLINIT_BEDIT,
CTLINIT_HEDIT, or CTLINIT_IEDIT in wParam, lParam points to
either a CTLINITBEDIT,
CTLINITHEDIT,
or CTLINITIEDIT
structure, respectively.
Comments
Each of the
CTLINIT structures has its first three members already initialized: cbSize
(size of the structure), hwnd (handle to the control window), and id
(child identifier of the control). The parent of the control can set
appropriate values to the rest of the members in the structure and the control
will then use those values when initializing itself.
