* Win32ADA Edit Control Notification @ 1999-04-28 0:00 Shawn Barber 1999-05-06 0:00 ` guru_upya 0 siblings, 1 reply; 3+ messages in thread From: Shawn Barber @ 1999-04-28 0:00 UTC (permalink / raw) I tried to use an edit control for the first time in a piece of software I am developing. I can't seem to trap the EN_CHANGE and the EN_UPDATE messages. I have been able to trap the EN_SETFOCUS and EN_KILLFOCUS messages. I need some new things to try. I've tried checking the high word of the wParam of a WM_SYSCOMMAND with no luck.

Try something like this: case message is when WM_COMMAND => declare wmID : Win32.WORD := Win32.WinDef.LOWORD(Win32.DWORD(WPARAM)); Notification_Code : Win32.WORD := Win32.WinDef.HIWORD(Win32.DWORD(WPARAM)); begin case Notification_Code is when EN_KILLFOCUS => if wmID = MY_EDIT_CONTROL_ID then . . . when EN_UPDATE => end; . . . I use a system where I use the extra bits in a Windows window to store a pointer to an Ada object and since the HWND is passed in the lParam: Control_Window : Pointer := To_GWindow( Win32.WinUser.GetWindowLong(To_HWND(lParam),Win32.WinUser.GWL_UserData) ); Then I can dispatch the Notification_Code directly to the Ada object that handles the control with: return On_Message(Control_Window, Message, wParam, lParam); Be well, David Botton guru_upya@yahoo.com wrote: > In previous versions of Windows, the notification code was in HIWORD(lParam) > for EN_KILLFOCUS.
