Is it okay to have one table for storing images against multiple tables - SQL Server 2008 R2 -

-

Is there a table to store images against multiple tables? Or is it better for three different tables? There may only be two images in the office.

Schema

  • Inspector - InspectorX (PK), Inspector's Name

    < / Li>

  • Office - OfficeID (PK), OfficeName

  • Employee - StaffID (PK), Staff name

New Photos table (collecting images in binary form for different tables) 

  Photos - Photo ID (PK) , PhotoData, InspectorAD (FK), OfficeID (FK), Staff ID (FK)

New Schema

  • Inspector - Inspectorector (PK), Inspector's Name, Photo ID (FK) 

      or
    • Photo IDI (FK) , Photo IDO (FK)

  • Office - OfficeID (PK), OfficeName, Photo ID (FK) Code> - Staff ID (PK), StaffName, Photo ID (FK)

this is ok But you do not need FK in both the photo table and the other tables. Just put the PhotoID FK in the other three tables.

If you are worried about the second picture only for the offices, then a second photographed in the office table It's OK to add an FK

If you want another scalable solution, and / or if more than one of the pictures can be used for more than one photo, then there may be a sequence.

Or if a picture can be related to only one unit, then you have one-to-many in the opposite direction, and you can put the FK column in the photo table, and you can add them to other entities. You can add an "Order" column to the photo table to remove the order from the table so that the ordering order for the photo can be specified in the photo, or any further information that can use that information.

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. ...
