Hi, I am trying to write a function that reads in individual lines from a txt file and stores them in a string array. The function works correctly except for when it reads in blank lines. Example: Function ifstream flinput( "somefile.txt" ) string line; while( getline(flinput, line) ) { //Add line to array So the problem is if th...
My recent turn-on is using BinaryFormatter instead of some database product. I have an idea to write simple 64bit number into hardware dongle, and encrypt my files with it - via simple XOR operation. Just so it can't be readable at some other end. Do I derive from Stream, or what? I know I can simply put that number into the file and...
I've been told that System.IO.MemoryStream need not be wrapped in a using block because there is no underlying resource, this kinda goes against what i've always been told about streams ("if in doubt, use a using"). Is this true? Why then does MSDN example use one (summarized below)? using(MemoryStream memStream = new MemoryStream(100...
I have an HTTP Handler that is binding an XmlTextWriter instance to Response.Output like so... Sub GenerateXml(ByRef Response As HttpWebResponse) Using Writer As New XmlTextWriter(Response.Output) ' Build XML End Using End Sub And now I also want the same XML to be saved to the local hard drive (in addition to being st...
I'm fetching a web page using the Apache httpcomponents Java library. After connecting the result I get is an HttpEntity which has a method getContent() which returns an InputStream and also has a method writeTo() which writes to an OutputStream. I want to turn the result into a String for extracting information. What is the most elegan...
I have create my code in order to write images in a remote sql server All the details of accessing and writing are fine until now, including the system account right now i'm in the command of: SqlFileStream = New SqlFileStream(filePathName, fileToken, FileAccess.Write) and when i'm trying to execute it the Server returns the error 'A...
I've written a simple chat program to experiment with some basic tcp/socket concepts. For some reason I've found that when I close my writer stream (which I am getting from the TcpClient.GetStream() function) it will send one final null message to my server. To top it all off it doesn't do this if I send one final message over the stream...
I am trying to write a function which will accept an InputStream with Zip file data and would return another InputStream with unzipped data. The Zip file will only contain a single file and thus there is no requirement of creating directories, etc. I tried looking at ZipInputStream and others but I am confused by so many different type...
Hi, I am trying upload multiple files using WCF. Since WCF only supports one stream I need to join multiple file streams together on the client and pass this to the service. The files might be huge and cannot be buffered in memory. How do I do this? Please show some code sample if you have. Regards, Rune ...
Hi, I have a simple text file, that has following content word1 word2 I need to read it's first line in my C++ application. Following code works, ... std::string result; std::ifstream f( "file.txt" ); f >> result; ... but result variable will be equal to "word1". It should be equal to "word1 word2" (first line of text file) Yes, i ...
I am trying to move from a mysql set to a postgres one, and one of the fields that I'm having trouble moving is a mysql LBLOB. I am trying to move it into a LargeObject type in postgres and I'm having some speed issues. I'm doing this in Java/Groovy and, frankly, the streaming business has me confused. I've tried two approaches: Hold...
I'm trying to write a recursive function that does some formatting within a file I open for a class assignment. This is what I've written so far: const char * const FILENAME = "test.rtf"; void OpenFile(const char *fileName, ifstream &inFile) { inFile.open(FILENAME, ios_base::in); if (!inFile.is_open()) { cerr << "Could...
Hello, I'm working with an ASCII input/output stream over a Socket and speed is critical. I've heard using the right Java technique really makes a difference. I have a textbook that says using Buffers is the best way, but also suggests chaining with DataInputStreamReader. For output I'm using a BufferedOutputStream with OutputStreamWri...
Any ideas on how to discard or reset the contents in a Process.StandardOutput, so we can discard the message of the day and any other initial content of a process? ...
I'm trying to implement my own QDebug() style debug-output stream, this is basically what I have so far: struct debug { #if defined(DEBUG) template<typename T> std::ostream& operator<<(T const& a) const { std::cout << a; return std::cout; } #else template<typename T> debug const& operator<<(T cons...
I have been coding Java for a while, but I have to admit that I don't get streams, buffers, etc. 100% I have tried to find a good tutorial on the subject that explains the reasoning behind them and their patterns of usage, but I couldn't find any. Only short, isolated snippets that don't help. Is there something out there? ...
First of all, I love ASP.NET MVC. This question is not a criticism of it. Rather, I want to confirm what I think I see and make sure I haven't missed something. Bear with me ... I can't get to the question without providing a little bit of context. The question has to do with returning data in a Stream in response to an HTTP Post. In th...
I am creating an IronPython engine more or less like so: var engine = IronPython.Hosting.Python.CreateEngine(); var scope = engine.CreateScope(); // my implementation of System.IO.Stream var stream = new ScriptOutputStream(engine); engine.Runtime.IO.SetOutput(stream, Encoding.UTF8); engine.Runtime.IO.SetErrorOutput(stre...
Note: Edited based on responses to receive more appropriate answers. I have a collection of C++ templates that I've made over the years, which I call Joop. It comprises mainly libraries that don't quite fall into the "general-purpose" category but are just useful enough that I keep slapping them into different projects, so most of them ...
I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds. Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files? Dim w_req As System.Net.HttpW...
