outputstream

问题 This was originally a part 2 of a different thread, but another use suggested that I separate the part 2 into it's own topic, so here we go. Original thread is here (Original Thread) I am using Jackcess to create a V2010 mdb file that I need to transfer to a client that will use Access 2013 to open it. Jackcess itself works - V2010 creates a file that Access 2013 can open when the file is FTP'd to the client by a third party software, such as FAR. However, when I try to upload this file to

问题 I am can try to run NHTTP(simple asynchronous HTTP server written in C# for the .NET framework. You can download this dll in nuget, or view source code on github) But i am cant write my own response to client from my server, because i am can't write to OutputStream. My powershell script: Add-Type -Path "NHttp.dll" $server = New-Object NHttp.HttpServer $server.EndPoint = new-object System.Net.IPEndPoint ([System.Net.IPAddress]::Parse("127.0.0.1"), 8080) $RequestReceived = { $request =

问题 I have a activity that contains a listview and sends different url when different list item is clicked via intent in onitemclicklistener In the singleitemview activity which is opened when list item is clicked i have a button to download images The problem is only 1 image is getting downloaded even different URLs are provided through different list item clicks I think this is happening because of providing only 1 outputstream like this OutputStream output = new FileOutputStream("/sdcard

问题 I've been trying to figure out this problem for hours now and I cant seem to figure it out. I'm trying to use JSch to SSH to a Linux computer from an Android phone. The commands always work fine but the output of the channel is usually empty. Sometimes it displays the output but most of the time it doesn't. Here's the code that I found online. String userName = "user"; String password = "test123"; String connectionIP = "192.168.1.13"; JSch jsch = new JSch(); Session session; session = jsch

问题 In Java, how can I find the name of the stream which is passed as an argument, provided the given stream is either System.err or System.out ? public String getStreamName(OutputStream arg0) { String streamName = ????; return "This is stream: " + streamName; } should return something like: This is stream: System.err I've tried arg0.toString() , but that doesn't seem useful, as the name returned is something like java.io.PrintStream@71cb25 and changes with each run. If the name was fixed, I

问题 this question could seem as duplicate, i have tried all the suggested solution but in vain , i wanna redirect python script output using this code : System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.StartInfo.FileName = "python.exe"; proc.StartInfo.Arguments = Application.StartupPath.Replace("\\bin\\Debug", "") + "\\scripts\\test.py"; proc.OutputDataReceived += OutputDataReceived; proc.ErrorDataReceived += ErrorDataReceived; proc.StartInfo.RedirectStandardOutput = true;

问题 I'm developing an android application that transfers images from one device to another. The received image will be stored in the local database of my application created by help of SQLite. To achieve my goals, I've converted the bitmap into byte[] and transferred it to another device by help of outputStream. I did achieve success from the above implementation but, failed in transferring the second image on the connected device. The problem which I am facing is the following: The first

问题 is there any possible way to write a file to a FTP directory using some sort of OutputStream without having to write a local file first? I've found some 3rd party libraries which achieve this, but I was wondering if there is some java "standard" class that makes it possible, I mean, some class that is packaged into the standar Java API. Thank you!! 回答1: URL url = new URL("ftp://user:pass@ftp.something.com/file.txt;type=i"); URLConnection urlc = url.openConnection(); InputStream is = urlc

问题 I'm using the following code to close an InputStream and an OutputStream from a connection to a server: try { if (mInputStream != null) { mInputStream.close(); mInputStream = null; } if (mOutputStream != null) { mOutputStream.close(); mOutputStream = null; } } catch (IOException e) { e.printStackTrace(); } However, the streams are not closing, they are still alive. If I connect again there are two different InputStreams. No exception is being caught in the catch section. What am I doing wrong

问题 In Java I need to put content from an OutputStream (I fill data to that stream myself) into a ByteBuffer. How to do it in a simple way? 回答1: You can create a ByteArrayOutputStream and write to it, and extract the contents as a byte[] using toByteArray() . Then ByteBuffer.wrap(byte []) will create a ByteBuffer with the contents of the output byte array. 回答2: There is a more efficient variant of @DJClayworth's answer. As @seh correctly noticed, ByteArrayOutputStream.toByteArray() returns a copy
