  • Creating a new log file each day

    - by Jason T.
    As the title implies how can I create a new log file each day in C#? Now the program may not necessarily run all day and night but only get invoked during business hours. So I need to do two things. How can I create a new log file each day? The log file will be have the name in a format like MMDDYYYY.txt How can I create it just after midnight in case it is running into all hours of the night?

  • Free en-GB dictionary for spell check in Silverlight

    - by Craig Shearer
    I'm trying to use the Vectorlight spell checker for Silverlight. The demo code comes with the en-US.dic file, but I'm trying to find a compatible one for British English. I have found one here but it doesn't work. The format seems similar to the en-US one, but it just doesn't work (i.e. it doesn't suggest any words).

  • Scheduled Task: Directory cleanup using windows batch script

    - by d03boy
    I have a shared disk that I would like to clean up once per week using a scheduled task of some sort. I would like to use a batch script so that the system admins can easily modify it or reuse it on other directories when needed. The directory has files with multiple file extensions but the ones that need to be deleted end in .bkf and must be over 2 weeks old. Does anyone have a batch script solution for this windows server (not sure which version)?

  • Any disadvantages to this tagging approach

    - by donpal
    I have a table of tags ID tag --- ------ 1 tagt 2 tagb 3 tagz 4 tagn In my items table, I'm using those tags in serialized format, comma delimited ID field1 tags ---- ------ ----- 1 value1 tagt,tagb 2 value2 tagb 3 value3 tagb,tagn 4 value4 When I need to find items that have this tag, I plan to deserialize the tags. But I'm not actually sure how to do it, and if it's better to have a third table for associations instead between the tags and the items.

  • IP address numbers in MySQL subquery

    - by Iain Collins
    I have a problem with a subquery involving IPV4 addresses stored in MySQL (MySQL 5.0). The IP addresses are stored in two tables, both in network number format - e.g. the format output by MySQL's INET_ATON(). The first table ('events') contains lots of rows with IP addresses associated with them, the second table ('network_providers') contains a list of provider information for given netblocks. events table (~4,000,000 rows): event_id (int) event_name (varchar) ip_address (unsigned 4 byte int) network_providers table (~60,000 rows): ip_start (unsigned 4 byte int) ip_end (unsigned 4 byte int) provider_name (varchar) Simplified for the purposes of the problem I'm having, the goal is to create an export along the lines of: event_id,event_name,ip_address,provider_name If do a query along the lines of either of the following, I get the result I expect: SELECT provider_name FROM network_providers WHERE INET_ATON('192.168.0.1') >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1 SELECT provider_name FROM network_providers WHERE 3232235521 >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1 That is to say, it returns the correct provider_name for whatever IP I look up (of course I'm not really using 192.168.0.1 in my queries). However, when performing this same query as a subquery, in the following manner, it doesn't yield the result I would expect: SELECT event.id, event.event_name, (SELECT provider_name FROM network_providers WHERE event.ip_address >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1) as provider FROM events Instead the a different (incorrect) value for network_provider is returned - over 90% (but curiously not all) values returned in the provider column contain the wrong provider information for that IP. Using event.ip_address in a subquery just to echo out the value confirms it contains the value I'd expect and that the subquery can parse it. Replacing event.ip_address with an actual network number also works, just using it dynamically in the subquery in this manner that doesn't work for me. I suspect the problem is there is something fundamental and important about subqueries in MySQL that I don't get. I've worked with IP addresses like this in MySQL quite a bit before, but haven't previously done lookups for them using a subquery. The question: I'd really appreciate an example of how I could get the output I want, and if someone here knows, some enlightenment as to why what I'm doing doesn't work so I can avoid making this mistake again. Notes: The actual real-world usage I'm trying to do is considerably more complicated (involving joining two or three tables). This is a simplified version, to avoid overly complicating the question. Additionally, I know I'm not using a between on ip_start & ip_end - that's intentional (the DB's can be out of date, and such cases the owner in the DB is almost always in the next specified range and 'best guess' is fine in this context) however I'm grateful for any suggestions for improvement that relate to the question. Efficiency is always nice, but in this case absolutely not essential - any help appreciated.

  • MS SQL: Primary file group is full

    - by aximili
    I have a very large table in my database and I am starting to get this error Could not allocate a new page for database 'mydatabase' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. How do you fix this error? I don't understand the suggestions there.

  • Internationalization of static pages with Rails

    - by Gavin
    I feel like I'm missing something really simple and I keep spinning my wheels on this problem. I currently have internationalization working throughout my app. The translations work and the routes work perfectly. At least, most of the site works with the exception of the routes to my two static pages, my "About" and "FAQ" pages. Every other link throughout the app points to the proper localized route. For example if I select "french" as my language, links point to the appropriate "(/:locale)/controller(.:format)." However, despite the changes I make throughout the app my links for the "About" and "FAQ" refuse to point to "../fr/static/about" and always point to "/static/about." To make matters stranger, when I run rake routes I see: "GET (/:locale)/static/:permalink(.:format) pages#show {:locale=/en|fr/}" and when I manually type in "../fr/static/about" the page translates perfectly. My Routes file: devise_for :users scope "(:locale)", :locale => /en|fr/ do get 'static/:permalink', :controller => 'pages', :action => 'show' resources :places, only: [:index, :show, :destroy] resources :homes, only: [:index, :show] match '/:locale' => 'places#index' get '/'=>'places#index',:as=>"root" end My ApplicationController: before_filter :set_locale def set_locale I18n.locale=params[:locale]||I18n.default_locale end def default_url_options(options={}) logger.debug "default_url_options is passed options: #{options.inspect}\n" { :locale => I18n.locale } end and My Pages Controller: class PagesController < ApplicationController before_filter :validate_page PAGES = ['about_us', 'faq'] def show render params[:permalink] end def validate_page redirect_to :status => 404 unless PAGES.include?(params[:permalink]) end end I'd be very grateful for any help ... it's just been one of those days. Edit: Thanks to Terry for jogging me to include views. <div class="container-fluid nav-collapse"> <ul class="nav"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"><%= t(:'navbar.about') %><b class="caret"></b></a> <ul class="dropdown-menu"> <li><%=link_to t(:'navbar.about_us'), "/static/about_us"%></li> <li><%=link_to t(:'navbar.faq'), "/static/faq"%></li> <li><%=link_to t(:'navbar.blog'), '#' %></li> </ul> </li>

  • WPF Reusing Xaml Effectively

    - by Steve
    Hi, I've recently been working on a project using WPF to produce a diagram. In this I must show text alongside symbols that illustrate information associated with the text. To draw the symbols I initially used some png images I had produced. Within my diagram these images appeared blurry and only looked worse when zoomed in on. To improve on this I decided I would use a vector rather than a rastor image format. Below is the method I used to get the rastor image from a file path: protected Image GetSymbolImage(string symbolPath, int symbolHeight) { Image symbol = new Image(); symbol.Height = symbolHeight; BitmapImage bitmapImage = new BitmapImage(); bitmapImage.BeginInit(); bitmapImage.UriSource = new Uri(symbolPath); bitmapImage.DecodePixelHeight = symbolHeight; bitmapImage.EndInit(); symbol.Source = bitmapImage; return symbol; } Unfortunately this does not recognise vector image formats. So instead I used a method like the following, where "path" is the file path to a vector image of the format .xaml: public static Canvas LoadXamlCanvas(string path) { //if a file exists at the specified path if (File.Exists(path)) { //store the text in the file string text = File.ReadAllText(path); //produce a canvas from the text StringReader stringReader = new StringReader(text); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas c = (Canvas)XamlReader.Load(xmlReader); //return the canvas return c; } return null; } This worked but drastically killed performance when called repeatedly. I found the logic necessary for text to canvas conversion (see above) was the main cause of the performance problem therefore embedding the .xaml images would not alone resolve the performance issue. I tried using this method only on the initial load of my application and storing the resulting canvases in a dictionary that could later be accessed much quicker but I later realised when using the canvases within the dictionary I would have to make copies of them. All the logic I found online associated with making copies used a XamlWriter and XamlReader which would again just introduce a performance problem. The solution I used was to copy the contents of each .xaml image into its own user control and then make use of these user controls where appropriate. This means I now display vector graphics and performance is much better. However this solution to me seems pretty clumsy. I'm new to WPF and wonder if there is some built in way of storing and reusing xaml throughout an application? Apologies for the length of this question. I thought having a record of my attempts might help someone with any similar problem. Thanks.

  • Reducer getting fewer records than expected

    - by sathishs
    We have a scenario of generating unique key for every single row in a file. we have a timestamp column but the are multiple rows available for a same timestamp in few scenarios. We decided unique values to be timestamp appended with their respective count as mentioned in the below program. Mapper will just emit the timestamp as key and the entire row as its value, and in reducer the key is generated. Problem is Map outputs about 236 rows, of which only 230 records are fed as an input for reducer which outputs the same 230 records. public class UniqueKeyGenerator extends Configured implements Tool { private static final String SEPERATOR = "\t"; private static final int TIME_INDEX = 10; private static final String COUNT_FORMAT_DIGITS = "%010d"; public static class Map extends Mapper<LongWritable, Text, Text, Text> { @Override protected void map(LongWritable key, Text row, Context context) throws IOException, InterruptedException { String input = row.toString(); String[] vals = input.split(SEPERATOR); if (vals != null && vals.length >= TIME_INDEX) { context.write(new Text(vals[TIME_INDEX - 1]), row); } } } public static class Reduce extends Reducer<Text, Text, NullWritable, Text> { @Override protected void reduce(Text eventTimeKey, Iterable<Text> timeGroupedRows, Context context) throws IOException, InterruptedException { int cnt = 1; final String eventTime = eventTimeKey.toString(); for (Text val : timeGroupedRows) { final String res = SEPERATOR.concat(getDate( Long.valueOf(eventTime)).concat( String.format(COUNT_FORMAT_DIGITS, cnt))); val.append(res.getBytes(), 0, res.length()); cnt++; context.write(NullWritable.get(), val); } } } public static String getDate(long time) { SimpleDateFormat utcSdf = new SimpleDateFormat("yyyyMMddhhmmss"); utcSdf.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles")); return utcSdf.format(new Date(time)); } public int run(String[] args) throws Exception { conf(args); return 0; } public static void main(String[] args) throws Exception { conf(args); } private static void conf(String[] args) throws IOException, InterruptedException, ClassNotFoundException { Configuration conf = new Configuration(); Job job = new Job(conf, "uniquekeygen"); job.setJarByClass(UniqueKeyGenerator.class); job.setOutputKeyClass(Text.class); job.setOutputValueClass(Text.class); job.setMapperClass(Map.class); job.setReducerClass(Reduce.class); job.setInputFormatClass(TextInputFormat.class); job.setOutputFormatClass(TextOutputFormat.class); // job.setNumReduceTasks(400); FileInputFormat.addInputPath(job, new Path(args[0])); FileOutputFormat.setOutputPath(job, new Path(args[1])); job.waitForCompletion(true); } } It is consistent for higher no of lines and the difference is as huge as 208969 records for an input of 20855982 lines. what might be the reason for reduced inputs to reducer?

    - by Pavel Radzivilovsky
    I have a U9 Telit modem which, at first, appears as a disk drive on USB bus. Then, the native software after autorun and install, sends a couple of IOCTLs to tell the device to reappear as other things. I can see them in procexp. I want to better spy on these, to know exactly what they send and how, in order to do the same in proper way.

  • Place images byte into String is not working?

    - by Proyb2
    I tried on Flex 3, facing issue with uploading JPG/PNG image, trace readUTFBytes would return correct bytes length but tmpFileContent is trucated, it would only appear to have upload just 3 characters of data to the server through PHP script which made image unusable. I have no issue for non-images format. What is wrong here? var tmpFileContent:String = fileRef.data.readUTFBytes(fileRef.data.length); Is String capable of handle bytes?
