How do you get the hwnd to the active child window? I want to give it focus when my main window regains focus.

Process the WM_KILLFOCUS message and store the currently focused control handle with GetFocus, when you recieve a WM_SETFOCUS message you restore the focus to the control using SetFocus.

Use API GetWindow with the GW_CHILD as uCmd.

Active child window?

donkey - it does'nt work! That's the first thing I tried. I have two list boxes side by side and naturally I want to restore focus to the correct one. But when I leave and return to the window I find that I can't cursor up/down with the keyboard - the SetFocus did not work.

Hi gfalen,

Yes you're right, it wouldn't work. Sorry it was late and I wasn't thinking perfectly clearly, I look at it in the clear light of morning and I ask myself "where did I get that from ?". I had seen that your post had received no replies and was in danger of being pushed off page one into obscurity so I decided to answer, but I should have thought more about it.

cath the window handle from LBN_SETFOCUS (or NM_SETFOCUS for listviews) message and restore handle when receiving WM_SETFOCUS.

Yes japeth, I'm trying to get around having to do this. It is only a partial solution. As soon as you add new controls you have to add 'special' code to proccess they're XX_KILLFOCUS messages too!

I'm having some luck with the WM_ACTIVATE message. It works in all cases except when you minimize from the system menu or the minimize button.

So I'm looking into the WM_SYSCOMMAND message right now.

For anyone interested this seems to work.

     

WndProc proc uses ebx edi esi, hwin, umsg, wparam, lparam

local hactive   

      

        ...



        case WM_ACTIVATE

            .if word ptr wparam == WA_INACTIVE

                invoke GetFocus

                .if eax != hwin && eax

                    mov hactive, eax

                .endif

            .else

                invoke SetFocus, hactive

            .endif
