Unable to uncheck a $DTS_SHOWNONE time

Recommended Posts

Consider the following time GUI box:

$my_time = GUICtrlCreateDate("", $x, $y, 85, 20, bitor($dts_timeformat,$DTS_SHOWNONE))

This is a standard Gui box showing just the time, but with a clever check/uncheck status to determine whether you actually want to use the contents of it or not.

Clicking on the checkbox works.

However, I'm completely unable to programatically check/uncheck the box. For instance:

GUICtrlSetState($my_time,$GUI_UNCHECKED)

doesn't unchecked it as expected.

I'm also unable to read the check status. Unchecking it doesn't seem to change the status nor data from a readable point of view.

How can I set and read this box?

DTS_SHOWNONE

It is possible to have no date currently selected in the control. With this style, the control displays a check box that users can check once they have entered or selected a date. Until this check box is checked, the application will not be able to retrieve the date from the control because, in essence, the control has no date. This state can be set with the DTM_SETSYSTEMTIME message or queried with the DTM_GETSYSTEMTIME message.

...according to http://msdn.microsoft.com/library/default....time/styles.asp

OK, that's great. Can someone possibly post a quick example of how this would work? I've not used GUICtrlSendMsg, and it doesn't seem obvious to me what to do.

cheers

Hmm. After fiddling about with GUICtrlSend/RecvMsg a bit, I've come up with the following:

#include <GUIConstants.au3>
#include <Date.au3>

GUICreate ("Date Test")
$dateBox = GUICtrlCreateDate ("16/01/2006", 10, 10, 100, 20, $DTS_SHORTDATEFORMAT + $DTS_SHOWNONE)
$label = GUICtrlCreateLabel ("", 10, 40, 100, 20)
$btn = GUICtrlCreateButton ("get", 10, 70, 40, 20)
$Label2 = GUICtrlCreateLabel ("", 10, 100, 100, 20)
GUISetState (@SW_SHOW)

Const $DTM_GETSYSTEMTIME = 0x1001; (I googled for these since MSDN doesn't seem to tell you!)
Const $DTM_SETSYSTEMTIME = 0x1002;
Do
    $msg = GUIGetMsg ()
    If $msg = $btn Then
        $lParam = GUICtrlRecvMsg ($dateBox, $DTM_GETSYSTEMTIME, 0, 1)
    ;$state = GUICtrlRead ($dateBox, 1)
        $asc = ""
        For $i = 1 To StringLen ($lParam)
            ConsoleWrite (Asc (StringMid ($lParam, $i, 1)) & " ")
        Next
        GUICtrlSetData ($label, $lParam)
        GUICtrlSetData ($Label2, GUICtrlRead ($dateBox))
    EndIf
until $msg = $GUI_EVENT_CLOSE

Click the 'get' button to fetch the checked state of the date picker using DTM_GETSYSTEMTIME. For me at least, it returns 0 when the box is ticked, and a byte string consisting of (255,15,1) when it's not. A bit weird but at least I can make it work.

Hi,

just had the same issue - wanted to uncheck the control. After some research and attempts, this is the only way which works for me:

...
$hControl= GUICtrlCreateDate("", 10, 10, 120, 22, $DTS_SHOWNONE)
...
GUICtrlSetState ($hControl,$GUI_FOCUS)
Send("{SPACE}")

Basically you are sending a space bar key stroke to the CTRL do uncheck it.

Works for me so far.

Hope this helps

Best

You're responding to a 5 1/2 year old thread, I doubt the poster is still looking for an answer


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I'm pretty sure that people who run into the same problem will still appreciate it. I would have done so if I could have found a solution to this problem.
