MessageBox changes the focus from edit control to main window

[jj2007]

I can't remember having seen that documented anywhere, but on Win7-64 at least, it's true. And it's a major nuisance

Testbed attached, pure Masm32 SDK code.

Code Select Expand


      .case WM_SETFOCUS
        invoke SetFocus,hEdit

Code Select Expand


      .case WM_SETFOCUS
        invoke SetFocus,hEdit


That works fine

(as long as you have only one edit control)

[hutch--]

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.

Interesting idea, thanks, but I've already implemented a more straightforward mechanism in the Santa Claus edition

I've already implemented a more straightforward mechanism

but that can return focus in other controls.

How that?

How that?

Your lack of imagination is deplorable

Your lack of imagination is deplorable

Your lack of arguments, too

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.

I'm a professional 

but you rarely prove your points.

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

Just in case. If you make a real program with a real interface, you can find that GetFocus don't return the Edit handle 

Like in this little program (and is not so complex):
