  • bind a two-dimensional array to a repeater - error

    - by Cristian Boariu
    Hi, I have this array: string[,] productData = new string[5,7]; I bind it to a repeater and a call a method like: <img src="<%# getPhoto1WithReplace(Container.ItemIndex) %>" which is defined like: public String getPhoto1WithReplace(Object itemIndex) { int intItemIndex = Int32.Parse(itemIndex.ToString()); if (productData[intItemIndex, 3] != null) return this.ResolveUrl(productData[intItemIndex, 3].ToString()); else return String.Empty; } I do not understand why it calls getPhoto1WithReplace with itemIndex as 5. My array has 5 indexes: 0,1,2,3,4, so HOW Container.ItemIndex can be 5...?

  • [IE 7/8] Loading HTML content in via Javascript nulls my <title> tag in some instances

    - by Simon
    This is an Explorer only problem and the symptoms are: I have links that when clicked will load in HTML chunks (none of which contain html header tags) using javascript. The html chunks are placed in various <div>s around the page, perhaps 3 different places with 3 different chunks brought in via javascript. When these chunks load in the <title> tag of the page gets set to <title></title> for some unknown (to me) reason. I've used the IE developer toolbar to confirm this by inspecting the DOM tree. I have other pages that do similar things but it does not seem to be a problem there.

  • Looking for a C# code parser

    - by Blindy
    I'm looking for a set of classes (preferably in the .net framework) that will parse C# code and return a list of functions with parameters, classes with their methods, properties etc. Ideally it would provide all that's needed to build my own intellisense. I have a feeling something like this should be in the .net framework, given all the reflection stuff they offer, but if not then an open source alternative is good enough. What I'm trying to build is basically something like Snippet Compiler, but with a twist. I'm trying to figure out how to get the code dom first. I tried googling for this but I'm not sure what the correct term for this is so I came up empty.

  • Need sorted dictionary designed to find values with keys less or greater than search value

    - by Captain Comic
    Hi I need to have objects sorted by price (decimal) value for fast access. I need to be able to find all objects with price more then A or less than B. I was thinkg about SortedList, but it does not provide a way to find ascending or descending enumerator starting from given key value (say give me all objects with price less than $120). Think of a system that accepts items for sell from users and stores them into that collection. Another users want to find items cheaper than $120. Basically what i need is tree-based collection and functionality to find node that is smaller\greater\equal to provided key. Please advice.

  • Parsing and validating arbitrary date formats in ruby (on rails)

    - by Matt Briggs
    I have a requirement to handle custom date formats in an existing app. The idea is that the users have to do with multiple formats from outside sources they have very little control over. We will need to be able to take the format and both validate Dates against it, as well as parse strings specifically in that format. The other thing is that these can be completely arbitrary, like JA == January, FE == February, etc... to my understanding, chronic only handles parsing (and does it in a more magical way then I can use), and enter code here DateTime#strptime comes close, but doesn't really handle the whole two character month scenario, even with custom formatters. The 'nuclear' option is to write in custom support for edge cases like this, but I would prefer to use a library if something like this exists.

  • What is the best method for implementing mouse wheel activity in Delph1 VCL forms?

    - by Brian Frost
    As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behaviour? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

  • Flagging complex properties as Browsable in the compact framework

    - by Rowland Shaw
    I'm working on a compact framework project and whilst most of the properties are fairly straight forward (I.e. mark them as browsable in the xmta file), I'm struggling to get this to work for more complex types - on the full framework, I'd just implement a custom TypeConverter and go from there, but it seems the CF TypeConverter doesn't have any of the type converting methods to override, which has left me a little stuck? It probably should be blindingly obvious but how would I go about supporting design time property support for more complex types (for the sake of argument, assume I can already convert to and from a string, but I'd prefer to keep this strongly typed, rather than just pretend it was a string and parse it both ways. Where should I be looking to achieve this?

  • Regex expression with leading zero

    - by user1874087
    I'm rather new to regex expressions and need help with a simple expression. I'm using Pentaho for ETL (Replace in String transformation) and I have column values that I need to add leading zeros to and parse out text as part of the database import. So far I have been unable to add the leading zero. The column is called Region and the values are "region 8", "region 10", "region 11". My regex expression is ['Region'] which will eliminate the region text but produces results = "8", "10", "11". I need values to produce "08", "10", "11". So all the single digit numbers must have leading zeros.

  • Get a string sequence from a node-set in xpath 1.0

    - by Miguel
    I'm using xpath 1.0 to parse an html file and I want to get a string sequence from a node-set. First I select a node-set (eg: //div) and then I want the string-value of each node of the set. I've tried with string(//div) but it only returns the string-value of the first node in the set. Example <foo> <div> bbbb<p>aaa</p> </div> <div> cccc<p>aaa</p> </div> </foo> I expect a result like ('bbbbaaa', 'ccccaaa') but I only get 'bbbaaa'

  • PHP - Too many mysql_query("SELECT .. ") .. ?

    - by Mike
    Hey, I'm making an e-shop and to display the tree of categories and all the products with their multiple variations of prices I made like more than 150 mysql_query("SELECT ..."); queries on one page. (If I count the "while" loops). Is it too many, and if yes, can it have any negative effect? (ofc. it takes longer to load the data ..) Also can I anyhow achieve the effect of this code without doing it that way? $result2 = mysql_query("SELECT * FROM ceny WHERE produkt_id='$id' ORDER BY gramaz"); $result3 = mysql_query("SELECT * FROM ceny WHERE produkt_id='$id' ORDER BY gramaz"); $result4 = mysql_query("SELECT * FROM ceny WHERE produkt_id='$id' ORDER BY gramaz"); $result5 = mysql_query("SELECT * FROM ceny WHERE produkt_id='$id' ORDER BY gramaz"); while( $row2 = mysql_fetch_array( $result2 )) { } while( $row3 = mysql_fetch_array( $result2 )) { } while( $row4 = mysql_fetch_array( $result2 )) { } while( $row5 = mysql_fetch_array( $result2 )) { } Thanks, Mike.

  • scanf formatting issue

    - by da_rockwilder
    I have a log file with the following format: INFO 2011-03-09 10:26:15,270 [user] message I want to parse the log file using PHP: // assume file exists and all that $handle = fopen("log_file.txt", "r"); while ($line_data = fscanf($handle, "%s %s %s [%s] %s\n")) { var_dump($line_data); } fclose($handle); When I run this code I get: [0]=> array(5) { [0]=> string(4) "INFO" [1]=> string(10) "2011-03-09" [2]=> string(12) "10:26:15,270" [3]=> string(5) "user]" [4]=> NULL } // snip It appears the closing bracket in the format string ("%s %s %s [%s] %s") is disrupting the rest of the line from getting parsed. I checked the PHP docs for scanf (as suggested by fscanf), and I didn't see anything mentioning having to escape a left bracket. Any suggestions on how to get the 4th and 5th elements to look like "user" and "message" respectively?

  • Passing data between Castle Windsor's Interceptors

    - by Nhím H? Báo
    I'm adopting Castle Windsor for my WCF project and feel really amazed about this. However, I'm having a scenario that I don't really know if Castle Windsor supports. For example I have the following chained Interceptors Interceptor 1 > Interceptor 2 > Interceptor 3 > Interceptor 4 > Real method Interceptor 1 returns some data and I want that to be available in Interceptor 2 Interceptor 2 in turn does it work and returns the data that I want to make avaialbe in the 3,4, interceptor. The real case scenario is that we're having a WCF service, Interceptor 1 will parse the request header into a Header object(username, password, etc.). The latter interceptors and real method will ultilize this Header object. I know that I can use Session variable to transport data, but is it a built-in, more elegant, more reliable way to handle this?

  • In python writing from XML to CSV, encoding error

    - by user574435
    Hi, I am trying to convert an XML file to CSV, but the encoding of the XML ("ISO-8859-1") apparently contains characters that are not in the ascii codec which Python uses to write rows. I get the error: Traceback (most recent call last): File "convert_folder_to_csv_PLAYER.py", line 139, in <module> xml2csv_PLAYER(filename) File "convert_folder_to_csv_PLAYER.py", line 121, in xml2csv_PLAYER fout.writerow(row) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe1' in position 4: ordinal not in range(128) I have tried opening the file as follows: dom1 = parse(input_filename.encode( "utf-8" ) ) and I have tried replacing the \xe1 character in each row before it is written. Any suggestions?

  • XMLEncoder and PersistenceDelegate

    - by Johannes Rössel
    I'm trying to use XMLEncoder to write an object graph (tree in my case) to a file. However, one class contained in it is not actually a Java bean and I don't particularly like making its guts publicly accessible. It's accessed more like a list and has appropriate add methods. I've already written a custom PersistenceDelegate to deal with that. However, is there any way for XMLEncoder to pick it up on its own or do I really need to add it whenever I use an encoder to write a graph that may contain said class?

  • SEO URL building - simple or hierarchy

    - by Pawel
    I run an online shop and I wonder what would be more SEO-friendly URL for a product page: a) domain.com/category-name/product-name OR b) domain.com/product-name I already have URL-s for product category pages with format domain.com/category-name. On one hand I heard (but cannot find proof for) that Google like tree hierarchies in URL (vote for "a"). On the other hand though longer URL could lead to smaller kewyord density, also "product_name" comes as the last URL part so probably the least important (vote for "b"). Maybe both options are equally SEO-effective? PS. I know about canonical URL's but this is not the case, I don't want/need both URL's formats, just want to choose the best.

  • Core Data fetch request with array

    - by JK
    I am trying to set a fetch request with a predicate to obtain records in the store whose identifiers attribute match an array of identifiers specified in the predicate e.g. NSString *predicateString = [NSString stringWithFormat:@"identifier IN %@", employeeIDsArray]; The employeeIDsArray contains a number of NSNumber objects that match IDs in the store. However, I get an error "Unable to parse the format string". This type of predicate works if it is used for filtering an array, but as mentioned, fails for a core data fetch. How should I set the predicate please?

  • Whats the best data-structure for storing 2-tuple (a, b) which support adding, deleting tuples and c

    - by bhups
    Hi So here is my problem. I want to store 2-tuple (key, val) and want to perform following operations: - keys are strings and values are Integers - multiple keys can have same value - adding new tuples - updating any key with new value (any new value or updated value is greater than the previous one, like timestamps) - fetching all the keys with values less than or greater than given value - deleting tuples. Hash seems to be the obvious choice for updating the key's value but then lookups via values will be going to take longer (O(n)). The other option is balanced binary search tree with key and value switched. So now lookups via values will be fast (O(lg(n))) but updating a key will take (O(n)). So is there any data-structure which can be used to address these issues? Thanks.

  • MVC Serve audio files while preventing direct linking using HttpResponseBase

    - by VinceGeek
    I need to be able to serve audio files to an mvc app while preventing direct access. Ideally the page would render with a player control so the user can start/stop the audio linked to the database record (audio files are in a folder not the db). I have a controller action like this: Response.Clear(); Response.ContentType = "audio/wav"; Response.TransmitFile(audioFilename); Response.End(); return Response; and the view uses the RenderAction method <% Html.RenderAction("ServeAudioFile"); %> this works but it won't display inline on the existing view, it opens a new page with just the media control. Am I totally barking up the wrong tree or is there a way to embed the response in the existing view? works exactly as I would like but I can't control access to the file.

  • Removing the Default Wrap Character From all records

    - by aceinthehole
    I am using BizTalk 2009 and I have a flat file that is similar to the following "0162892172","TIM ","LastName ","760 "," ","COMANCHE ","LN " "0143248282","GEORGE ","LastName ","625 "," ","ENID ","AVE " When I parse it and start mapping it I need to get rid of the quotation marks. I have marked the Wrap Character attribute for the schema as a quotation mark but it doesn't remove it when BizTalk is parsing the file. Is there an easy way to specify the removal of a wrap character or am I going to have to run it through a script functiod every time? Also I would like to be able to remove the trailing spaces as well, if at all possible.

  • How do I store in subversion my customizations to a public open source project?

    - by Clyde
    Hi, I'm working on customizing a couple of open source projects in ways that are very much personalized -- i.e., not appropriate to send the patches back to the maintainers for the public. One of them is stored in CVS, one in SVN. I use SVN for my own work. The CVS project is fine. I check the tree in to my svn repository, including the CVS directories. I can commit all my changes, and still do a cvs update to stay up to date with bug fixes/features of the public project. How should I work on the svn project? Is there a 'best practice' or known procedure for this kind of scenario?

  • XML DOM Manipuation

    - by kunalsawlani
    Hi, I am new to XML and have been trying some simple examples and they work fine. I want to do something like the following, but I am not able to figure out how to go about doing this. I have a HTML web page, where the user types in some data in an input field. I want to take that data, parse it to create an XML string, and the apply XSLT transformation to it, and display the result back on the page. All this needs to be done on the client browser, with JavaScript. If some one could point out the steps or the general procedure to go about doing this, it would be great. I have been looking over the net, but the information is so vast, that I have not been able to locate exactly what I need. Thanks
