  • Writing custom sections into app.config

    - by Michael M.
    I want to save some custom data into application configuration file and I need to create some custom sections in app.config. Reading custom data from app.config is simple task, but I can't write information from my programm into app.config. For finding solution of this problem I create test project. For reading data from custom section app.config I used information from this article: http://devlicio.us/blogs/derik_whittaker/archive/2006/11/13/app-config-and-custom-configuration-sections.aspx

  • Problem with Writing files using FileWriter automatically with Quartz Scheduler

    - by Jeeva
    I have chosen nearly 200 files to write on a position automatically on a particular time. Created a separate job names in Quartz scheduler. The job will be triggered on a time. I can read the files only after all the files have been written. I could not read after one file is written. I have closed the FileWriter after one file written. What is the solution to access the file and read which have been written into the hard Disk

  • Writing tests for Rails plugins

    - by Adam
    I'm working on a plugin for Rails that would add limited in-memory caching to ActiveRecord's finders. The functionality itself is mature enough, but I can't for the life of me get unit tests to work with the plugin. I now have under vendor/plugins/my_plugin/test/my_plugin_test.rb a standard subclass of ActiveSupport::TestCase with a couple of basic tests. I try running 'rake test' from the plugin directory, and I have confirmed that this task loads the ruby file with the test case, but it doesn't actually run any of the tests. I followed the Rails plugin guide (http://guides.rubyonrails.org/plugins.html) where applicable, but it seems to be horribly outdated (it suggests things that Rails now do automatically, etc.) The only output I get is this: Kakadu:ingenious_record adam$ rake test (in /Users/adam/Sites/1_PRK/vendor/plugins/ingenious_record) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -Ilib:lib:test "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb" "test/ingenious_record_test.rb" The simplest test case looks like this: require 'test_helper' require 'active_record' class IngeniousRecordTest < ActiveSupport::TestCase test "example" do assert false end end This should definitely produce at least some output, and the only test in that file should produce a failed assertion. Any ideas what I could do to get Rails to run my tests?

  • Lots of questions about file I/O (reading/writing message strings)

    - by Nazgulled
    Hi, For this university project I'm doing (for which I've made a couple of posts in the past), which is some sort of social network, it's required the ability for the users to exchange messages. At first, I designed my data structures to hold ALL messages in a linked list, limiting the message size to 256 chars. However, I think my instructors will prefer if I save the messages on disk and read them only when I need them. Of course, they won't say what they prefer, I need to make a choice and justify the best I can why I went that route. One thing to keep in mind is that I only need to save the latest 20 messages from each user, no more. Right now I have an Hash Table that will act as inbox, this will be inside the user profile. This Hash Table will be indexed by name (the user that sent the message). The value for each element will be a data structure holding an array of size_t with 20 elements (20 messages like I said above). The idea is to keep track of the disk file offsets and bytes written. Then, when I need to read a message, I just need to use fseek() and read the necessary bytes. I think this could work nicely... I could use just one single file to hold all messages from all users in the network. I'm saying one single file because a colleague asked an instructor about saving the messages from each user independently which he replied that it might not be the best approach cause the file system has it's limits. That's why I'm thinking of going the single file route. However, this presents a problem... Since I only need to save the latest 20 messages, I need to discard the older ones when I reach this limit. I have no idea how to do this... All I know is about fread() and fwrite() to read/write bytes from/to files. How can I go to a file offset and say "hey, delete the following X bytes"? Even if I could do that, there's another problem... All offsets below that one will be completely different and I would have to process all users mailboxes to fix the problem. Which would be a pain... So, any suggestions to solve my problems? What do you suggest?

  • Writing to a specific line of a file.

    - by helpmeh
    I have a .dat file with data like this in "James","Project5","15/05/2010","3" "Matt","Project1","01/05/2010","5" "Ellie","Project5","24/04/2010","1" "Ellie","Project2","10/05/2010","3" "Matt","Project3","03/05/2010","4" It gets written in with thise code. Private Sub Command2_Click() Open jobs For Append As #1 Write #1, Combo1, Combo3, Combo2, Text3 Close #1 End Sub I instead would like to write it to the file so that if a persons name is already in the file then it would just put the data in the file, under their that is already there but without the name. I can't figure out how to do this but this is what I would like it to end up like. "James","Project5","15/05/2010","3" "Matt","Project1","01/05/2010","5" "Ellie","Project5","24/04/2010","1" "Project2","10/05/2010","3" "Matt","Project3","03/05/2010","4" Any help would be fantastic!

  • Best Practise for Writing a POS System

    - by Gary
    Hi, I'm putting together a basic POS system in C# that needs to print to a receipt printer and open a cash drawer. Do I have to use the Microsoft Point of Service SDK? I've been playing around with printing to my Samsung printer using the Windows driver that came with it, and it seems to work great. I assume though that other printers may not come with Windows drivers and then I would be stuck? Or would I be able to simply use the Generic/Text Driver to print to any printer that supports it? For the cash drawer I would need to send codes directly to the COM port which is fine with me, if it saves me the hassle of helping clients setup OPOS drivers on there systems. Am I going down the wrong path here? Thanks, Gary

    I intend to develop an SMS gateway in c#, but i am doubtful about it's feasibility, because my initial research had shown that an SMS gateway had to cover for protocol differences. So what exactly a gateway had to do, further if i use SMPP, so is it possible to send/receive SMS to/from any number in the world by simply using SMPP ?

  • utf8 codification problem C#, writing a tex file, and compiling with pdflatex

    - by voodoomsr
    Hi, i have the next code written in C#....it create a tex file using utf-8.....the problem is that appears that is not a real valid utf-8 file because, when i use pdflatex it doesn't recognize the characters with accents. Somebody knows a way to write a real UTF-8 file? When i use TexmakerX to create a utf8 file with the same latex code, pdflatex doesn't complaints, so the problem must be in the generation. FileInfo file = new FileInfo("hello.tex"); StreamWriter writer = new StreamWriter("hello.tex", false, Encoding.UTF8); writer.Write(@"\documentclass{article}" + "\n" + @"\usepackage[utf8]{inputenc}" + "\n" + @"\usepackage[spanish]{babel}" + "\n" + @"\usepackage{listings}" + "\n" + @"\usepackage{fancyvrb}" + "\n" + @"\begin{document}" + "\n" + @"\title{asd}" + "\n" + @"\maketitle" + "\n" + @"\section{canción}" + "\n" + @"canción" + "\n" + @"\end{document}"); writer.Close();

  • Can someone provide an example of seeking, reading, and writing a >4GB file using boost iostreams

    - by Queueless
    I have read that boost iostreams supposedly supports 64 bit access to large files semi-portable way. Their FAQ mentions 64 bit offset functions, but there is no examples on how to use them. Has anyone used this library for handling large files? A simple example of opening two files, seeking to their middles, and copying one to the other would be very helpful. Thanks.

  • Android: writing a file to sdcard

    - by Sumit M Asok
    I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. All I could find was using the openFileOutput("",MODE_WORLD_READABLE) method, of the activity but how my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. Please, someone help me? CODE: File file = new File(bgdmanip.savLocation); FileOutputStream filecon = null; filecon = new FileOutputStream(file); // bgdmanip.savLocation holds the whole files path byte[] myByte; myByte = Base64Coder.decode(seReply); Log.d("myBytes", String.valueOf(myByte)); bos.write(myByte); filecon.write(myByte); myvals = x * 11024; seReply is a string reply from HttpPost response. the second set of code is looped with reference to x. the file is created but remains 0 bytes

  • How to overcome vc++ warning C4003 while writing common code for both gcc and vc++

    - by compbugs
    I have a code that is compiled in both gcc and vc++. The code has a common macro which is called in two scenarios. When we pass some parameters to it. When we don't want to pass any parameters to it. An example of such a code is: #define B(X) A1##X int main() { int B(123), B(); return 0; } The expect output from the pre-processing step of compilation is: int main() { int A1123, A1; return 0; } The output for both gcc and vc++ is as expected, but vc++ gives a warning: warning C4003: not enough actual parameters for macro 'B' How can I remove this warning and yet get the expected output? Thanks.
