  • C# pulling out columns from combobox text

    - by Mike
    What i have is four comboboxes and two files. If the column matches the combobox i need to write it out to a file but it has to appened with the second combobox. So for example Combobox1: Apple | Orange Combobox2: Pineapple | Plum I have selected Apple Plum I need to search threw a text file and find whatever columns is Apple or Plum: Orange|Pear|Peach|Turnip|Monkey|Apple|Grape|Plum and then i need to write out just the columns Apple|Plum to a new text file. Any help would be awesome! Better example Combobox1 selected item:Apple Combobox2 selected item:Plum Text FILE: APPLE|Pear|Plum|Orange 1|2|3|4 215|3|45|98 125|498|76|4 4165|465|4|65 Resulting File: 1|3 215|45 125|76 4165|4 Thanks for the advice, i dont need help on adding to combobox or reading the files, just how to create a file from a delimited file having multiple columns.

  • How to Use .NET Assembly from Legacy SQL Server 2000 DTS

    - by shyneman
    Hi All, I have a .NET assembly that needs to be called from a DTS package. There are two options I am considering to get this to work: 1) write a COM-callable wrapper for the .NET assembly and have the VBScript create the COM object to use 2) write a .NET command-line exe that uses that .NET assembly and have the VBScript execute that exe Can anybody comment on the pros/cons of either approach and which is the better way of doing this? If there are other solutions, I'd love to hear them too. Thanks a lot for any input.

  • IIS7 Modules - managed or native?

    - by Simon Linder
    Hi all, as the old ISAPI filters are going to die sooner or later, I want to rewrite an old ISAPI filter that was used in IIS 6 into a module for use in IIS 7. The module will be used globally, meaning it will be used within each site, on a Windows Server 2008 R2 with IIS 7.5 installed, that will host several thousand web sites and managing about 50 application pools. My question now is if I should write that module in managed or unmanaged code? One of my concerns regarding managed code is the massive memory consumption due to the .NET framework overhead. I don't know how this would effect the server's performance. I already wrote modules in managed as well as in unmanaged code. So this is not the bothering my decision. But I would prefer to write the module in C# if there are no huge drawbacks. Any suggestions about that issue?

  • C# setup project output automatically start with administrative rights

    - by Alex
    Hi, i've created an setup project for a .net-application which works fine. The problem is, that the application begins to write log-files after startup and this requires administrative rights on windows vista and windows 7. I know there are some folders which i could use to write into without administrative rights. When i start the application as administrator, everything works fine. I asked myself, if it's possible to change the setup project in visual studio in a way that the installed application automatically owns administrative rights on the target system? Thanks for every help in advance! Alex

  • try...else...except syntax error

    - by iform
    I can't understand this... Cannot get this code to run and I've no idea why it is a syntax error. try: newT.read() #existingArtist = newT['Exif.Image.Artist'].value #existingKeywords = newT['Xmp.dc.subject'].value except KeyError: print "KeyError" else: #Program will NOT remove existing values newT.read() if existingArtist != "" : newT['Exif.Image.Artist'] = artistString print existingKeywords keywords = os.path.normpath(relativePath).split(os.sep) print keywords newT['Xmp.dc.subject'] = existingKeywords + keywords newT.write() except: print "Cannot write tags to ",filePath Syntax error occurs on the last "except:". Again...I have no idea why python is throwing a syntax error (spent ~3hrs on this problem).

  • A web framework where AJAX was not an after thought

    - by Pirate for Profit
    AJAX is a pain in the ass because it essentially means you'll have to write two sets of similarish code: one for browsers with JavaScript enabled and those without. Not only this, but you have to connect JavaScript events to hook into your models and display the results. And if all that weren't bad enough, you need to send an address change with the request, otherwise the user won't be able to "click back" correctly (if confused look at what happens to the address bar when you click links in GMail). We're searching for something that had the foresight and design goals with all these concerns in mind. Performance and security are also obvious major concerns. We love config-based systems as well, where you don't have to write a lot of code you just drop it into an easily read config format. It's like asking for the holy grail right?

  • jQuery Plugin Overwriting Parameters

    - by Travis
    Hey Everyone, This maybe a very mundane question, but this is the first jQuery plugin that I write and I'm a bit fuzzy on understanding the scope rules in Javascript. I'm trying to write an simple jQuery plugin that wraps around the Stack Overflow API. I'm starting off by trying to work with the Flair API. I wanted to make the plugin as configurable as possible so that you can easily pass it the domain and user id, and generate multiple Flairs. var superUser = $.jStackOverflow.flair({domain:"superuser.com", id: 30162, parentId:'#su-flair'}); var stackOverflow = $.jStackOverflow.flair({domain:"stackoverflow.com", id: 55954, parentId:'#so-flair'}); The problem is, when it makes the second call, its somehow using the correct domain and id parameters, but the parentId field that it's using in the callback function to create the html, is using the first parameter. You can see the plugin here and the html here

  • Run shell script using fabric and piping script text to shell's stdin

    - by Peter Lyons
    Is there a way to execute a multi-line shell script by piping it to the remote shell's standard input in fabric? Or must I always write it to the remote filesystem, then run it, then delete it? I like sending to stdin as it avoids the temporary file. If there's no fabric API (and it seems like there is not based on my research), presumably I can just use the ssh module directly. Basically I wish fabric.api.run was not limited to a 1-line command that gets passed to the shell as a command line argument, but instead would take a full multi-line script and write it to the remote shell's standard input.

  • Do Websites need Local Databases Anymore?

    - by viatropos
    If there's a better place to ask this, please let me know. Every time I build a new website/blog/shopping-cart/etc., I keep trying to do the following: Extract out common functionality into reusable code (Rubygems and jQuery plugins mostly) If possible, convert that gem into a small service so I never have to deal with a database for the objects involved (by service, I mean something lean and mean, usually built with the Sinatra Web Framework with a few core models). My assumption is, if I can remove dependencies on local databases, that will make it easier and more scalable in the long run (scalable in terms of reusability and manageability, not necessarily database/performance). I'm not sure if that's a good or bad assumption yet. What do you think? I've made this assumption because of the following reason: Most serious database/model functionality has been built on the internet somewhere. Just to name a few: Social Network API: Facebook Messaging API: Twitter Mailing API: Google Event API: Eventbrite Shopping API: Shopify Comment API: Disqus Form API: Wufoo Image API: Picasa Video API: Youtube ... Each of those things are fairly complicated to build from scratch and to make as optimized, simple, and easy to use as those companies have made them. So if I build an app that shows pictures (picasa) on an Event page (eventbrite), and you can see who joined the event (facebook events), and send them emails (google apps api), and have them fill out monthly surveys (wufoo), and watch a video when they're done (youtube), all integrated into a custom, easy to use website, and I can do that without ever creating a local database, is that a good thing? I ask because there's two things missing from the puzzle that keep forcing me to create that local database: Post API RESTful/Pretty Url API While there's plenty of Blogging systems and APIs for them, there is no one place where you can just write content and have it part of some massive thing. For every app, I have to use code for creating pretty/restful urls, and that saves posts. But it seems like that should be a service! Question is, is that what the website is? ...That place to integrate the worlds services for my specific cause... and, sigh, to store posts that only my site has access to. Will everyone always need "their own blog"? Why not just have a profile and write lots of content on an established platform like StackOverflow or Facebook? ... That way I can write apps entirely without a database and know that I'm doing it right. Note: Of course at some point you'd need a database, if you were doing something unique or new. But for the case where you're just rewiring information or creating things like videos, events, and products, is it really necessary anymore??

  • SQL Server: export data via SQL query?

    - by rlb.usa
    I have FK and PK all over my db and table data needs to be specified in a certain order or else I get FK/PK insertion errors. I'm tired of executing the wizard again and again to transfer data one table at a time. In the SQL Server export data wizard there is an option to "Write a query to specify the data to transfer". I'd like to write the query myself and specify the correct order. Will this solve my problem? How do I do this? Can you provide a sample query (or link to one) The databases are on two different servers - SQL Server 2008 on each ; The database names & permissions are the same ; each table name & col is the same ; I need Identity Insert for each table.

  • Strange results - I obtain same value for all keys

    - by Pietro Luciani
    I have a problem with mapreduce. Giving as input a list of song ("Songname"#"UserID"#"boolean") i must have as result a song list in which is specified how many time different useres listen them... so a output ("Songname","timelistening"). I used hashtable to allow only one couple . With short files it works well but when I put as input a list about 1000000 of records it returns me the same value (20) for all records. This is my mapper: public static class CanzoniMapper extends Mapper<Object, Text, Text, IntWritable>{ private IntWritable userID = new IntWritable(0); private Text song = new Text(); public void map(Object key, Text value, Context context) throws IOException, InterruptedException { /*StringTokenizer itr = new StringTokenizer(value.toString()); while (itr.hasMoreTokens()) { word.set(itr.nextToken()); context.write(word, one); }*/ String[] caratteri = value.toString().split("#"); if(caratteri[2].equals("1")){ song.set(caratteri[0]); userID.set(Integer.parseInt(caratteri[1])); context.write(song,userID); } } } This is my reducer: public static class CanzoniReducer extends Reducer<Text,IntWritable,Text,IntWritable> { private IntWritable result = new IntWritable(); public void reduce(Text key, Iterable<IntWritable> values, Context context) throws IOException, InterruptedException { Hashtable<IntWritable,Text> doppioni = new Hashtable<IntWritable,Text>(); for (IntWritable val : values) { doppioni.put(val,key); } result.set(doppioni.size()); //doppioni.clear(); context.write(key,result); } } and main: Configuration conf = new Configuration(); Job job = new Job(conf, "word count"); job.setJarByClass(Canzoni.class); job.setMapperClass(CanzoniMapper.class); //job.setCombinerClass(CanzoniReducer.class); //job.setNumReduceTasks(2); job.setReducerClass(CanzoniReducer.class); job.setOutputKeyClass(Text.class); job.setOutputValueClass(IntWritable.class); FileInputFormat.addInputPath(job, new Path(args[0])); FileOutputFormat.setOutputPath(job, new Path(args[1])); System.exit(job.waitForCompletion(true) ? 0 : 1); Any idea???

  • Using multiple aggregate functions in an algebraic expression in (ANSI) SQL statement

    - by morpheous
    I have the following aggregate functions (AGG FUNCs): foo(), foobar(), fredstats(), barneystats(). I want to know if I can use multiple AGG FUNCs in an algebraic expression. This may seem a strange/simplistic question for seasoned SQL developers - however, the but the reason I ask is that so far, all AGG FUNCs examples I have seen are of the simplistic variety e.g. max(salary) < 100, rather than using the AGG FUNCs in an expression which involves using multiple AGG FUNCs in an expression (like agg_func1() agg_func2()). The information below should help clarify further. Given tables with the following schemas: CREATE TABLE item (id int, length float, weight float); CREATE TABLE item_info (item_id, name varchar(32)); # Is it legal (ANSI) SQL to write queries of this format ? SELECT id, name, foo, foobar, fredstats FROM A, B (SELECT id, foo(123) as foo, foobar('red') as foobar, fredstats('weight') as fredstats FROM item GROUP BY id HAVING [ALGEBRAIC EXPRESSION] ORDER BY id AS A), item_info AS B WHERE item.id = B.id Where: ALGEBRAIC EXPRESSION is the type of expression that can be used in a WHERE clause - for example: ((foo(x) < foobar(y)) AND foobar(y) IN (1,2,3)) OR (fredstats(x) <> 0)) I am using PostgreSQL as the db, but I would prefer to use ANSI SQL wherever possible. Assuming it is legal to include AGG FUNCS in the way I have done above, I'd like to know: Is there a more efficient way to write the above query ? Is there any way I can speed up the query in terms of a judicious choice of indexes on the tables item and item_info ? Is there a performance hit of using AGG FUNCs in an algebraic expression like I am (i.e. an expression involving the output of aggregate functions rather than constants? Can the expression also include 'scaled' AGG FUNC? (for example: 2*foo(123) < -3*foobar(456) ) - will scaling (i.e. multiplying an AGG FUNC by a number have an effect on performance?) How can I write the query above using INNER JOINS instead?

  • Total of unknown categories in SSRS 2005

    - by Lijo
    Hi, I am working with SSRS2005. I have requirement to display total in the footer. We have to display the total of each category. What I used to do is, write expression for all category names and hide those totals that are not having any value in the current selection. Mango Count = sum(iif(fields!Category.Value = “Mango”,0,1)) Apple Count = sum(iif(fields!Category.Value = “Apple”,0,1)) However, in the new requirement, I don’t have the knowledge of categories. It could be any number of categories. Is it possible to write an expression for this? Please help Thanks Lijo Cheeran Joseph

  • Is there a nice XSL stylesheet for client-side DocBook rendering?

    - by Steven Huwig
    I want the DocBook documents in my SVN repository to look nice if someone looks at them in a web browser. I've started to write a CSS stylesheet, but I think that it will have significant limitations -- particularly ones regarding hyperlinks. There is a large body of DocBook XSL stylesheets at the DocBook site , but they don't seem to be appropriate for browser rendering. I don't want to generate static documents and put them into SVN. I want them to be basically readable for other developers without much hassle. I could write my own browser-appropriate XSL stylesheet to convert DocBook to HTML, but it seems like someone else must have already done this. I just don't know where to find it.

  • How to do call function after client finishes download from tornado web server?

    - by Shabbyrobe
    I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado. I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text: class CrapHandler(BaseHandler): def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) print "done" I get the following output from tornado immediately after making the request: done I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done. Also, if I do the following I get pretty much the same result: class CrapHandler(BaseHandler): @tornado.web.asynchronous def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) self.finish() print "done" Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?

    Hi All, As I am very new to programming, I am very curious about learning the best ways/practices of programming. Whenever I want to write any program , I strat directly with coding while some guys say that you should plan your program first before starting the code. But I don't understand the real value of creating the class diagrams and all that kind of stuff coz I think that ultimately I have to write the code. Can you guys please share your experiences about how you are doing your programming means what is your first step when you start an application.

  • Check which nodes of Beowulf HPC cluster system are free from PHP app?

    - by Skuja
    I am working on my diploma thesis project. I have access to 32Node Dell poweredge HPC cluster system with Linux(Debian i think) installed on it. My first goal is to create web (PHP) app where logged users could see free and busy nodes, turn them on and off. I am planning to do something like this - write some cron daemon that would run every 30seconds or other interval, and it could run ping utility for each node to find out if it is on or off, then write results to some file. Then from my web app i could read the info. Will it be a good solution? What existing for node management solutions are there?

  • Requirements of an issue/bug tracker

    - by James Brooks
    I've been looking at various issue/bug trackers available on the net. There are some very good ones, but I'm unable to use them as my server does not support Perl/Ruby (for example), I'm not too bothered however because I am able to write code in PHP and as such would prefer something in that language. So I've taken it upon myself to write a custom issue tracker system. As of now it's in early planning stages, and before I continue, I'd like to find out what people need from such an application. My current list of things to add include: Creating/Editing/Deleting issues - both on user and admin level Related issues (similar to that of STO) Admins will be able to create builds/milestones and version control of projects Admins will be able to assign users/groups to a project Roadmap of projects Possible SVN integration with Git? What do you think? There are a couple more things I'd like to add, but I'm sure you'll think of a better way of adding such feature. What would you like to see from an issue tracker?
