mysql - Update all post that is not in another table -

-

मेरे पास इस tow तालिका है: - 

  an_post आईडी का नाम बॉडी पिक दिनांक बनाएँ

और तालिका 2 है: - 

  an_taxonomy PostId TaxId

हमें table 1 < / Code> में तालिका 2 में एक रिकार्ड है, वह वील है ("10", "1") ।

जहां 10 < / Code> है PostId , और 1 है टैक्सआईडी ।

कैसे तालिका 2 सभी पोस्ट तालिका 1 से मान ("post_id", "1") , और पहले जोड़ा नहीं।

इसे डुप्लिकेट नहीं करना चाहिए तालिका 2 में दर्ज करें

अगर PostId an_taxonomy तालिका पर एक अनन्य अनुक्रमणिका है तो केवल 

  एक_taxonomy (PostId, TaxId) का चयन करें आईडी, 1 से an_post

में प्रवेश करें, यदि नहीं तो आपको यह देखना चाहिए कि पंक्ति पहले से मौजूद है या नहीं । इस तरह से कुछ: - 

  an_taxonomy में प्रविष्ट करें (पोस्ट आईडी, कर आईडी) SELECT a.ID, 1 से an_post एक बाएं OUTER पर an_taxonomy b में शामिल करें a.ID = b.PostId और b, TaxId = 1 WHERE b.PostId NULL है

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. ...
