  • Obj-c Turning long string into multidimensional array

    - by Phil
    I have a long NSString, something like "t00010000t00020000t00030000" and so on. I need to split that up into each "t0001000". I'm using... NSArray *tileData = [[GameP objectForKey:@"map"] componentsSeparatedByString:@"t"]; And it splits it up, but the "t" is missing, which I need (although I think I could append it back on). The other way I guess would be to split it up by counting 8 char's, although not sure how to do that. But ideally I need it split into a [][] type array so I can get to each bit with something like... NSString tile = [[tileData objectAtIndex:i] objectAtIndex:j]]; I'm new to obj-c so thanks for any help.

  • Repeater not repeating :0) (asp.net)(vb)

    - by Phil
    Morning stackoverflow, I have a repeater, with the following code in my aspx page; <asp:Repeater ID="Contactinforepeater" runat="server"> <HeaderTemplate> <h1>Contact Information</h1> </HeaderTemplate> <ItemTemplate> <table width="50%"> <tr> <td colspan="2"><%#Container.DataItem("position")%></td> </tr> <tr> <td>Name:</td> <td><%#Container.DataItem("surname")%></td> </tr> <tr> <td>Telephone:</td> <td><%#Container.DataItem("telephone")%></td> </tr> <tr> <td>Fax:</td> <td><%#Container.DataItem("fax")%></td> </tr> <tr> <td>Email:</td> <td><%#Container.DataItem("email")%></td> </tr> </table> </ItemTemplate> <SeparatorTemplate> <br /><hr /><br /> </SeparatorTemplate> </asp:Repeater> Then I have this code in my aspx.vb to get the data; If did = 0 Then s = "sql works on db server" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", Data.SqlDbType.Int) x.Parameters("@contentid").Value = contentid c.Open() r = x.ExecuteReader r.Read() Contactinforepeater.DataSource = r Contactinforepeater.DataBind() End If c.Close() r.Close() If Not did = 0 Then s = "sql works on db server" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", SqlDbType.Int) x.Parameters("@contentid").Value = contentid x.Parameters.Add("@did", SqlDbType.Int) x.Parameters("@did").Value = did c.Open() r = x.ExecuteReader r.Read() Contactinforepeater.DataSource = r Contactinforepeater.DataBind() End If r.Close() c.Close() If 'did' is or is not '0' I still get no data outputted to the page. I just get the 'contact information' h1 header from the header template. I've tested the value of s in sqlsms and it works fine. Position, surname, telephone, fax, email all exist in the db. The particular page I am checking exists and has 1 set of contact information attached. Where am I going wrong? Thanks! ps. Does my syntax appear correct? pps. I am also open to different ways of achieving the same result. I tried via an sqldatasource but ran into problems when using variables as params (there is no option to select them, only controls, querystring etc)

  • Do you code variables in your language?

    - by Phil Hannent
    I am just working on a project where the library has an object with the property color, however being British I always use colour when writing variables and properties. I also just found some legacy code where the British developer used color in a variable name. Is American English the default for development now?

  • An example of advanced database search

    - by Phil
    Hi there, im looking for an example script. I saw one yesterday but for the life of me I can't find it again today. The task I have is to allow the user to search 1 database table via input controls on an aspx page where they can select and , or , equals to combine fields, generating the sql on the fly with a stringbuilder or similar. (it runs behind the corp firewall) Please can someone point me in the right direction of an example or tutorial I've been working on the page, but have run into problems. Here is a snippet; If NameSearch.Text IsNot String.Empty And andor1v IsNot "0" Then sql += "Surname LIKE '%" & name & "%' " & andor1v & " " ElseIf NameSearch.Text IsNot String.Empty And andor1v Is "0" Then sql += "Surname LIKE '%" & name & "%' " End If

  • What is wrong with my SQL syntax for an UPDATE with a JOIN?

    - by Phil H
    I have two tables, related by a common key. So TableA has key AID and value Name and TableB has keys AID, BID and values Name, Value: AID Name 74 Alpha AID BID Name Value 74 4 Beta Brilliance I would like to update the TableB Value here from Brilliance to Barmy, using just the Name fields. I thought I could do it via an UPDATE containing a JOIN, but Access (I know...) is complaining with 'Syntax error (missing operator) in query expression ' and then everything from 'Barmy' here: UPDATE tB SET tB.BValue='Barmy' FROM TableB tB INNER JOIN TableA tA ON tB.AID=tA.AID WHERE tB.Name='Beta' AND tA.Name='Alpha'; What is my heinous crime? Or is it just Access not conforming?

  • What algorithm would you use to code a parrot?

    - by Phil H
    A parrot learns the most commonly uttered words and phrases in its vicinity so it can repeat them at inappropriate moments. So how would you create a software version? Assuming it has access to a microphone and can record sound at will, how would you code it without requiring infinite resources? The best I can imagine is to divide the stream using silences in the sound, and then use some pattern recognition to encode each one as a list of tokens, storing new ones as you meet them. Hashing the token sequences and counting occurrences in a database, you could build up a picture of the most frequently uttered phrases. But given the huge variety in phrases, how do you prevent this just becoming a huge list? And the sheer number of pairs to match would surely generate lot of false positives from the combinatorial nature of matching. Would you use a neural net, since that's how a real parrot manages it? Or is there another, cleverer way of matching large-scale patterns in analogue data?

  • Unable to Connect to Management Studio Server

    - by Phil Hilliard
    I have a nasty situation. I am using Microsoft SQL Server Management Studio Express edition locally on my pc for testing, and once tested I upload database changes to a remote server. I have a situation where I deleted the Default Database on my local machine, and instead of searching hard enough to find an answer to that problem, I uninstalled and reinstalled Management Studio. Since then Management Studio has not been able to connect to the server. Is there any help (or hope for me for that matter), out there????? The following is the detailed error message: =================================== Cannot connect to LENOVO-E7A54767\SQLEXPRESS. =================================== A network-related or instance-specific error occurred while establishing a connection to SQL Server.

  • Copy/publish images linked from the html files to another server and update the HTML files referenci

    - by Phil
    I am publishing content from a Drupal CMS to static HTML pages on another domain, hosted on a second server. Building the HTML files was simple (using PHP/MySQL to write the files). I have a list of images referenced in my HTML, all of which exist below the /userfiles/ directory. cat *.html | grep -oE [^\'\"]+userfiles[\/.*]*/[^\'\"] | sort | uniq Which produces a list of files http://my.server.com/userfiles/Another%20User1.jpg http://my.server.com/userfiles/image/image%201.jpg ... My next step is to copy these images across to the second server and translate the tags in the html files. I understand that sed is probably the tool I would need. E.g.: sed 's/[^"]\+userfiles[\/image]\?\/\([^"]\+\)/\/images\/\1/g' Should change http://my.server.com/userfiles/Another%20User1.jpg to /images/Another%20User1.jpg, but I cannot work out exactly how I would use the script. I.e. can I use it to update the files in place or do I need to juggle temporary files, etc. Then how can I ensure that the files are moved to the correct location on the second server

  • Is there a neater way to get the first occurrence of something?

    - by Phil H
    I have a list which contains a number of things: lista = ['a', 'b', 'foo', 'c', 'd', 'e', 'bar'] I'd like to get the first item in the list that fulfils a predicate, say len(item) > 2. Is there a neater way to do it than itertools' dropwhile and next? first = next(itertools.dropwhile(lambda x: len(x) <= 2, lista)) I did use [item for item in lista if len(item)>2][0] at first, but that requires python to generate the entire list first.

  • getting active records to display as a plist

    - by phil swenson
    I'm trying to get a list of active record results to display as a plist for being consumed by the iphone. I'm using the plist gem v 3.0. My model is called Post. And I want Post.all (or any array or Posts) to display correctly as a Plist. I have it working fine for one Post instance: [http://pastie.org/580902][1] that is correct, what I would expect. To get that behavior I had to do this: class Post < ActiveRecord::Base def to_plist attributes.to_plist end end However, when I do a Post.all, I can't get it to display what I want. Here is what happens: http://pastie.org/580909 I get marshalling. I want output more like this: [http://pastie.org/580914][2] I suppose I could just iterate the result set and append the plist strings. But seems ugly, I'm sure there is a more elegant way to do this. I am rusty on Ruby right now, so the elegant way isn't obvious to me. Seems like I should be able to override ActiveRecord and make result-sets that pull back more than one record take the ActiveRecord::Base to_plist and make another to_plist implementation. In rails, this would go in environment.rb, right?

  • Do you employ any tools for managing technical debt?

    - by Phil.Wheeler
    The site I work with on a day-to-day basis has its share of shortcomings and we often make design decisions to "get us by right now" with the intention of fixing those up later. I've found that making the time to actually go back and fix them, let alone remembering what the full list of to-do items is can be challenging at best. Can you recommend any tools, resources or tricks that help you effectively manage your technical debt?

  • Unusual conversion error (string to integer) asp.net

    I have my repeater item template: <ItemTemplate> <tr><td><%#Container.DataItem("Category")%></td></tr> </ItemTemplate> Hooked up to: s = "SQL that works ok on server" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", SqlDbType.Int) x.Parameters("@contentid").Value = contentid c.Open() r = x.ExecuteReader If r.HasRows Then Linksrepeater.DataSource = r Linksrepeater.DataBind() End If c.Close() r.Close() When I run the code I get: Invalid Cast Exception was not handled by user code (Conversion from string "category" to type 'Integer' is not valid.) I'm not sure how / why it is trying to convert "Category" to integer as in the db it is a string. Can you please tell me how to avoid this error? thanks.

    - by Phil
    I have a class includes.vb that holds some variables (sharing them with other pages) like: Public Shared pageid As Integer = 0 I then have a function that does some work with these variables returning them with values; Return pageid When I step through the code, the variables have values (while stepping through the function), but when they are returned to the page, they come back null. Do they loose value everytime a page is loaded? Can you suggest an alternative method? Thanks a lot.

  • Show/Hide divs with same class - jquery

    - by phil
    Hello, I have 1 div that will contain 3-5 divs with the same class. Below the div is an anchor. I would like for when this anchor is clicked it will hide the first div and then show the second. Another click would show the next and so on. I have set display:none on all divs but the first so only one is currently showing. I just can't figure out how to hide the first and then show the second, then third, then next when clicking the anchor. <div class="container-div"> <div class="inner-div">...</div> <div class="inner-div" style="display:none;">...</div> <div class="inner-div" style="display:none;">...</div> <a href="#" class="more">More</a> </div> So when the more anchor is clicked it would show one inner-div one at a time. Any suggestions or ideas would be greatly appreciated. Also, I would like to use jquery to accomplish this.
