freepascal - Pascal - size of array -

-

I have a code in which I write each number in 1 line until I write it. I am confused about the size of the array In the beginning I have declared that the array with the A1 to 5 is array. But when I keep writing and put more than 5 numbers, it seems that it is still left and then the latter is used for bicycles. How is that possible? I thought I would get an error if I was out of the index. 

  Programmasters; Var Hermes, I: Integer; A: array [1. 5] of integer; I started: = 0; Repetitive Inc (i); Readln (a [i]); If A [i] = 0 then HMEs: = I-1; Until one [i] = 0; I: for = 1 hmez do writeln (a [i]); End.

You are overwriting memory which is a variable This can be a leak of memory due to an unrestricted exception (run-time error) or any other "strange" behavior sooner or later, in run-time probes of array indexes in 'managed' languages ​​such as C # or Java in parcel Optional feature is not mandatory, applicable language facility.

Pascal compilers usually have the option to turn on or off array index check, which is called 'class check', directive {$ R +} Changes - See.

In your case the code seems to be 'work', because there is probably no other useful variable, after the space allocated for A please note in memory it is just an incredible And this can not happen in all the runways of your program. So generally, your program is wrong.

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. ...
