I can't remember having seen that documented anywhere, but on Win7-64 at least, it's true. And it's a major nuisance :sad:
Testbed attached, pure Masm32 SDK code.
.case WM_SETFOCUS
invoke SetFocus,hEdit

That works fine :thumbsup:
(as long as you have only one edit control)
At least you can pick which one via the handle. If you have multiple edit windows, you would need a mechanism to switch the handles to the one you are using at the time.
You can subclass all edits, and store the handle in a global variable (lastEdit) when they receive WM_SETFOCUS. :thumbsup:

Interesting idea, thanks, but I've already implemented a more straightforward mechanism in the Santa Claus edition (http://masm32.com/board/index.php?topic=94.0) :winking:

Your lack of imagination is deplorable :biggrin:
Your lack of arguments, too :tongue:
Show me how the MsgBox macro could "return focus in other controls". You love criticising, but you rarely prove your points. Make an effort, demonstrate that you are decent coder.
The problem is so easily solved.
Set a GLOBAL variable.
As each edit control gets the focus, set its handle to that GLOBAL.
Easy, peasy, sleazy, greasy !

That requires a handler - an overkill. My solution is short and foolproof.

Some times is better that who receive the critic find the way, and I know You can :biggrin:

Just in case. If you make a real program with a real interface, you can find that GetFocus don't return the Edit handle :biggrin:
Like in this little program (and is not so complex):

Sorry, it's unplublished yet (and advance is very slow :eusa_boohoo:).
But the trick, apparently, is not a secret :biggrin:

The "trick" is an overkill. Besides, I am looking forward to see a working example. I invite you to modify the simple template at the beginning of this thread - plain Masm32. Btw I
do use a global variable, see here (http://www.jj2007.eu/pics/MsgBoxKeepFocus.png).
It's more complicated than you think.

I don't see the problem:
Yep, you don't see the problem :thumbsup:
mov ebx, rv(GetFocus)
invoke MessageBox, 0, chr$("Focus will change"), chr$("Title"), MB_OK
push eax
invoke SetFocus, hEdit
pop eax
pop ebx
If you have more than one edit, you must use hEdit to store the active edit handle.

You are moving closer now :thumbsup:
