smart device - GeneXus: Websession's contents will not be preserved between calls to Refresh -

-

I have to replenish my grid every time the user has set a new date (data from WebServity). According to the event triggering order, I was thinking:

(1) Action event: Call a process to get the data, transform it, fill it up the SDT and place it on a web site.

(2) Refresh Event: Rebuild local SDT with new values.

(3) Load Event: Load the grid.

However, when I make it, I see a warning:

spc0185: not refreshed in the middle of calls to refresh the content of the website Will be done.

And I can confirm that the behavior is a bit strange (the grid only refreshes the user on the fist time, the date changes). 

  Events and myDate.ControlValueChanged Composite Setgrization (& mydate) Refresh Endcompatch & Event Event Refresh & amp; Mydate = ctod (& websession.get ('newDate')) to refresh date // var & amp; MyJSON = & amp; Websession.get ('GridJSON') & mySDT.FromJson (& myJSON) and event event load & amp; ; MySDTItem & amp; MySDT and field 1 = & amp; MySDTI Tem.field1 & amp; Field2 = & amp; MySDTItem.field2 & amp; Field3 = & amp; MySDTItem.field3 load end endevent

Is there any alternative solution for this?

Thanks

I have every & amp; How can I fill the grid in myDate variant?

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
