  • Silverlight RichTextBox Disable Mouse Selection

    - by Fastidious
    I am writing a custom control based on RichTextBox that needs the ability to process MouseLeftButtonDown events but must not allow user-initiated selection (I'm doing everything programmatically). I tried setting a flag in MouseLeftButtonDown to track dragging and then continuously setting the RichTextBox.Selection to nothing in the MouseMove event but the move event isn't fired until after I release the mouse button. Any ideas on how to solve this? Thanks.

  • Eclipselink read complex object model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

  • iPhone: Compressing .app files in command line (Mac OS X) removes CodeSigning

    - by Santthosh
    I am trying to do a simple build automation of my iPhone apps with TeamCity, but having this nagging issue.. When I manually pickup and install .app file from the build folder it works great (syncs smoothly with iTunes and I can see the app on my phone) But when I try to zip this with /bin/zip or ditto...then the zipped contents loose the CodeSigning (iTunes says that it cannot install this app because its not signed) I have tried different combinations of these.. ditto -ck --rsrc --keepParent HelloWorld.app HelloWorld.zip Any more ideas?

  • Programmers - I have a question for you.

    - by jens
    My boyfriend does coding (Rails/C?/PHP) for a job and I don't know what he would appreciate on our first anniversary. Does anyone have any ideas? Yes, he's stereotypical geek, but I'd rather not give a pack of Bawls for an anniversary gift. He dislikes going anywhere, so "experiences" like going to an event are out. Maybe I should just have a giant LAN party in the house.

  • Algorithm putting point into square with maximal minimum distance

    - by Mikulas Dite
    I'm stuck on this: Have a square. Put n points into this square so the minimal distance (not necessary the average distance) is the highest possible. I'm looking for an algorithm which would be able to generate the coordinates of all points given the count of them. Example results for n=4;5;6: Please don't mention computing-power based stuff such as trying a lot of combination and then nitpicking the right one and similar ideas.

  • Changing array values in a VBA dictionary

    - by Pawan Jain
    Hi I have a piece of code that does not seem to do what it is expected to do. VBA Arrays are mutable by all means, but it seems that when they are stored into a Dictionary as values of some keys, they are not mutable anymore. Any ideas? Sub foo() Dim mydict As New Dictionary mydict.Add "A", Array(1, 2, 3) MsgBox mydict("A")(1) ' The above shows 2, which is fine mydict("A")(1) = 34 MsgBox mydict("A")(1) ' The above also shows 2, which is not fine End Sub

  • Font Anti-Aliasing on iPad SDK

    - by Felix Khazin
    I'm using a custom pixel font on the iPad SDK, and I'm trying to find a way to disable font anti-aliasing for UIFont. Pixel fonts usually work best when they don't have Anti-aliasing. I disable it easily in Photoshop when I create static resources, but this time I need a dynamic output with the custom font. Any ideas? Thanks.

  • Convert Unicode char to closest (most similar) char in ASCII (.net)

    - by Andrey
    Hi all! Do you have any idea how to covert different Unicode characters to their closest ASCII equivalents? Like Ä - A. A googled but didn't find any suitable solution. Trick Encoding.ASCII.GetBytes("Ä")[0] didn't work. (Result was ?). I found that there is class Encoder that has Fallback property that is exactly for cases when char can't be converted, but implementations (EncoderReplacementFallback) are stupid and convert to ?. Any ideas? Thanks, Andrey

  • Kohana ORM syntax question

    - by anthony
    I'm using the "join_table" function with Kohana's ORM to build a query. The following works: $category = ORM::factory('category')->join_table('product'); But this doesn't: $category = ORM::factory('category'); $category->join_table('product'); The documentation uses the second as an example, but it returns 0 while the first example returns "categories_products" which is correct. Any ideas?

  • Need to have either example.com/username or username.example.com, but how?

    - by Stefan
    Hey guys, I'm almost finished developing my large project, however I would love it if I could make it so instead of having the users profile pages at: http://example.com/profile/username/USERNAME (i'm currently using .htaccess to rewrite the GET data into forward slashes and profile(.php) being read as just 'profile' profile.php also parses the url correctly to retrieve the GET data) But it would be some much better if I could do it so that it's like http://www.example.com/USERNAME (preferred) or http://www.USERNAME.example.com Any ideas or resources? Thanks, Stefan
