vb.net - Problems creating folders in vb -

-

I can not create a folder in drive C: Using VB.NET it says, "Access is denied" I Tried a lot of ways but it does not work. I have tried to use this code: 

  If my.Computer.FileSystem.DirectoryExists ("C: \ log.txt") then the system to use as author. IO.TextWriter = System.IO file. CreateText ("C: \ Log. TTTT") author. Viryline (m and amp; vbCrLf & "top") author. Virline (M. Left and VBCRF & "LRFT") "SA Writer Writer. WrightLine (Me.Width & amp; vbCrLf & amp; "Width") Authors. Use other directory to finish WriteLine (Me.High & amp; vbCrLf & amp; "Height"). CreateDirectory ("C: \ log.txt") Use the system as the author. IoActochrower = System. IOFILE Crete Text ("C: \ Log. TT TT") Writer. Whiteline (100 and VBCRLF) Authors Viraline (100 and VBCRLF) "An author writer (100 & amp; vbCrLf) writer.WriteLine (100 & amp; vbCrLf) ends use if

should I do?

The problem appears that you are getting the concept of directory (i.e. folders) First of all, with files , you see whether a folder named log.txt is present. If it exists, you can use a new name Trying to create a file On the contrary, if the log.txt folder is not present, you create the folder, and then you try to create a file with the same name in the same place. , It is always going to fail, you can not create a file named log.txt , if there is already a folder with the same name in the same place.

I doubt That's what you want to check if Folder C: \ file that folder in For example, something like this: 

  If My.Computer.FileSystem.DirectoryExists ("C: \") then the author of the system Use. IO.TextWriter = System.IO.File.CreateText ("C: \ log.txt") ... ... Finally use another directory. CreateDirectory ("C: \") Use the system as the author. IO.TextWriter = System.IO.File.CreateText ("C: \ log.txt" ... ... end the end use if

this is definitely a more logical meaning However, in this special case, since C: \ It is a little silly drive, so it will always be present (unless the drive volume is present, in which any folder will fail by making the folder.)

As Plutonics told in the above comments, even if it works you, it is still bad Practice is quite possible, if it is not possible, then the user will not have access to the root of C: drive. This is the separate storage , or system's temporary folder, or user's application data folder, or Somewhere else that is likely to be accessible will be a priority for writing.

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. ...
