Properly convert an array to string in 8086 assembly -

-

I have an array

INPUT 10 DUP (?)

something After the operation, I have to print this array to mov ah, 9

  • finally put $?
  • What is 0DH and 0h after a string? Prior: Prompt 'This is a string', 0h, 0h, '$'

< P> You have an empty array or at least one undetermined content.

You have to fill it with something to be able to print it. To start with

, you can try input 10 dup (?) instead of 'input db test', '$ " . This will put the word "test" in the memory space labeled "Input" after "$".

Then you will need to print whatever you put in the app: 

  mov dx, offset input # wants the BIOS "input" location # Point at (movable with your "test" string) mov ah, 9 # wants BIOS call 9 (a string prints by $ a) int 21h # run BIOS call

Once you have your work, you can worry about how you can fill "input" from another source, such as the user Ut (BIOS calls 1h or 0ah be helpful). Adding a $ character at the end of the string will probably involve a mov [register] 24h or something similar (ascii code for 24 hours "$"). As <@>

@Rold said in the comments, 0ah and 0dh are the characters that you put in the end of the string to the next line of the next string down.

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. ...
