How to find the IDC in the CUSTOM event??

[Mark Strickland]

I need the IDC_ of the control in a CUSTOM event.  I am using a SENDMESSAGE to do a KILLFOCUS (without setting the focus to a new control) and I need the IDC value.

Is there some way to get the IDC_ value while in the CUSTOM event?

Hi Mark,

If you know the HWND of the Control then you can easily get the IDC_ using GetWindowLong.

Code Select Expand


idCtrl = GetWindowLong( hwndControl, %GWL_ID)


Hope this is what you are looking for.

Thanks for the reply.

My Masked Edit functions have sort of gotten "out of control" (no pun intended).

I have some functions that handle input of SSN/PHONE/DATE and other special formats on the fly as you type.  I was trying to handle the ESCAPE key as an "abort" of sorts for a form.  I was using SETFOCUS in the CUSTOM event for next control in the Z order and was causing problems.

If I do a SENDMESSAGE ... KILLFOCUS then the SETFOCUS of the next control in the Z order does not fire.

Thanks for the help.

Maybe you can use something like the following to set focus to the next control in the zorder:

Code Select Expand


SetFocus GetNextDlgTabItem( hWndForm, hWndControl, %FALSE)


If I do a SENDMESSAGE ... KILLFOCUS then the SETFOCUS of the next control in the Z order does not fire.

I am pretty sure that I read somewhere that you should not explicitly send a WM_KILLFOCUS message to controls.

I tested and a SENDMESSAGE with a KILLFOCUS does what I need.

Previously I used the code below to change the focus in the CUSTOM event to handle function keys.

Code Select Expand


FF_CONTROL_SETFOCUS GETNEXTDLGTABITEM(hWndForm, hWndControl, %FALSE)


This caused a SETFOCUS event on the next control in Z order before the KILLFOCUS on the control where I pressed the function key and it caused a problem with how I am editing fields.

When I do this (below) it fires KILLFOCUS but without moving focus to any other control first.

Code Select Expand


SENDMESSAGE hWndForm, %wm_command, MAKDWD(GETWINDOWLONG( hWndControl, %GWL_ID),%en_killfocus),hWndControl


I will be aware to look for problems based on your previous comment.

Thanks.
