CBaseControlWindow::PossiblyEatMessage

The PossiblyEatMessage method forwards keyboard and mouse messages to a specified window.

Syntax

BOOL WINAPI PossiblyEatMessage(
    HWND hwndDrain,
    UINT uMsg,
    WPARAM wParam,
    LPARAM lParam
)

Parameters

hwndDrain

Handle of the window to which messages will be forwarded.

uMsg

Message that was forwarded.

wParam

First message parameter.

lParam

Second message parameter.

Return Value

Returns TRUE if the message was posted or FALSE if it wasn't.

Remarks

When the window is owned, it will pass certain classes of messages to the owning window (such as keyboard and mouse events). In this case, the Win32 PostMessage function is used to post messages to any window specified by hwndDrain which is set in CBaseControlWindow::put_MessageDrain. If a certain message cannot be posted, this message will return FALSE.

The following is a list of messages that will get passed on untranslated and return TRUE.
