Far be it for me to be advising you Peter but I do have a thought:

Don't you need a CallBack to trap the %IDC_SYSDATETIMEPICK32_1 Control click and then restore the Focus to whichever Control had it before the %IDC_SYSDATETIMEPICK32_1 click?

DTN_CLOSEUP Notification

I knew better than to advise Peter L on anything regarding PB ("Don't you need a CallBack to trap ...") then went ahead and did it anyway. {arrrghh}

So, I thought wisely, maybe I ought to try what I preached. And, to no one's suprise I'm sure, it didn't work. {sigh}

I'd say

except my 2002 version of the fm does not include what it should: "This notification message is sent in the form of a WM_NOTIFY message. "

I wonder what the current doc at msdn says....let me look....hmm, that's interesting.

Halfway there

Okay Peter, I got you halfway there. The cursor returns to the textbox it was in before the Date control is chosen. But there's just one minor problem as you'll see if you run the code. It works with En_change so a tb needs to have been tyoed in. Probably other msgs would work better.

Mike, I played around with your suggestion but got nowhere. Without actual code for me to see/clip/paste/copy/agonize_over, cryptic clues are lost on this dummy, even if they are in the manual.

Here are a couple of ways to keep the keyboard focus on the Date Time Picker once the SysMonthCal has been displayed..

Code:

    Case %WM_NCACTIVATE  ' Leaves focus on DTP control after SysMonthCal closes
      Static hWndSaveFocus As Dword
      If IsFalse CbWParam Then
        hWndSaveFocus = GetFocus()
      ElseIf hWndSaveFocus Then
        SetFocus(hWndSaveFocus)
        hWndSaveFocus = 0
      End If

I believe MCM was alluding to something like..

Code:

 
    Case %WM_NOTIFY
     Local lpNmhdr As NMHDR Ptr
      lpNmhdr = CbLParam
      Select Case @lpNmhdr.idFrom
        Case %IDC_SYSDATETIMEPICK32_1
          Select Case @lpNmhdr.code
            Case %DTN_CLOSEUP
              Control Set Focus CbHndl, %IDC_SYSDATETIMEPICK32_1 ' change ID to send elsewhere or
              'SetFocus GetNextDlgTabItem(CbHndl, @lpNmhdr.hWndFrom , %FALSE)  ' next Tab item
          End Select
      End Select

Both your methods look simpler than mine, Dave. which involves subclassing the DTP. In any case Peter's question has been answered (I hope).

In any case Peter's question has been answered (I hope).

Yes, thanks all. It was a bit annoying if you have a form displayed, that after every sysdate control the focus went to the first control on the dialog...

**Michael Mattias** · 25 Aug 2008, 07:19 PM

>that after every sysdate control the focus went to the first control on the dialog...

I think that actually might be the expected behavior.

Windows does not remember focus, and if the window on which it was focused (the dropdown) is suddenly gone (destroyed) , it really has no where to go except to the first tabstop control of whatever window it decides to make active.

That's why all that 'boilerplate' code re "hwndSaveFocus" is generated by PBFORMS is there... to 'remember' the last focused control. (Your example in Post #1 had NO callbacks and so never did any of that stuff).
