Hi All,
Does anyone know of a way to find out which dialog element has the focus with VDS 3.x?

Not possible in VDS 3.x to find out what the focus is on. Unless there's some API for that. VDS 4 does have that though "@focus()".

Thanks Garrett
For the reply so since there is no way to do this with VDS. I wrote a DLL to do get the handle of the control that has the focus  I will be posting it soon for everyone out there...

Mindpower,
That's really nice of you... Thanks for making the dll and for passing it on to others.

Well it is somewhat possible, you can use the 'DESIGN' style which is undocumented. It will generate a CLICK event for all controls I think.
DIALOG CREATE,New Dialog,-1,0,240,160,DESIGN
The other hidden commands are DIALOG ATTACH and DIALOG DETACH, which attachs/detachs the resizing arrows on the control, you probably wont need these to get focus however.
Just keep a variable marked whenever a click event is made for any control and you'll know which one last had the mouse/focus. |

Nice idea Prakash, however...
DESIGN causes a CLICK event as long as the element is clicked on,
but not using the TAB key. Also, since it generates a CLICK event for
all elements, it kills many standard events (BUTTON, EXIT, etc.), and
practically eliminates access to COMBO list items...

| Code: |
rem -- VDS3 & VDS4 compatible --
OPTION SCALE, 96
Title By Mac
DIALOG CREATE,Design Style,-1,0,300,200,DESIGN
DIALOG ADD,BUTTON,B1,5,5,60,20
DIALOG ADD,TEXT,T1,8,70,,," Text Element "
DIALOG ADD,EDIT,E1,30,5,290,20,"Edit Element",,EXIT
DIALOG ADD,COMBO,C1,55,5,290,20,"Combo Element"
DIALOG ADD,LIST,L1,80,5,290,115
DIALOG ADD,STATUS,Stat,"Focus ="
DIALOG SHOW
LIST ADD, L1, List Element
LIST LOADTEXT, C1,
"Option 1
"Option 2
"Option 3
"Option 4
:EVLOOP
WAIT EVENT
%e = @event()
DIALOG SET,Stat,"Focus = "@substr(%e, 1, @diff(@len(%e),5))
goto %e
:B1BUTTON
rem -- Not accessible ---
INFO This is a BUTTON event...
goto EVLOOP
:E1EXIT
rem -- Not accessible ---
INFO Edit EXIT event...
goto EVLOOP
:B1CLICK
:T1CLICK
:E1CLICK
:C1CLICK
:L1CLICK
INFO This is a CLICK event...
goto EVLOOP
:CLOSE
EXIT

Another option might be to just extract the element name from
standard events (CLICK, BUTTON, etc.).
