DELPHI XE7 [dcc32 Error] E2250 There is no overloaded version of 'Pos' that can be called with these arguments -

-

itemprop = "text">

Delphi XE7 on Win7 32 bit code: 

  Process TForm1.IdMappedPortTCP1Execute (AContext: TIdContext ); (Position ('Connect', AContext) & lt; & gt; 0) or (Position ('Received', AContext) & lt; & gt; 0) or (Position ('POST', AContext) <0 (OR) (Pos ('HEAD', AContax) & lt;> 0) Then (....) Sleep (100); End;

Error: 

  [dcc32 error] Unit1.pas (49): E2250 is there that can be said with either of 'status' How to fix the code  
 Thanks in advance  After the argument for the text "Itemprop =" text "> 
  pos  are two strings. The function searches for the first occurrence (first parameter) of a substring inside a string (the second parameter). The function is documented here: 
 
 You have  AContext  type  TIdContext  which is passing and that is not a string. To fix the code, you need to pass the string that contains the text in which you want to search.

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. ...
