  • does != nil check for 0x0?

    - by 4thSpace
    I have a custom class and check that a property isn't 0x0 by doing: if(myinstance.someproperty != nil){ //do something } However, even if someproperty is 0x0, I still go into the conditional. someproperty is of another class type. Is there some other way to check this?

  • Java: Check if file is already open

    - by hello_world_infinity
    I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?

  • formatting european characters from JSON results

    - by mlecho
    hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

  • drupal views block arguments

    - by slimcady
    I currently have a view (Drupal 6 using Views2) that properly aggregates a custom content type (videos) and filters them for a page display. When I create a block display, it previews the results in live preview just great, but when i go to the page expecting to see the block it doesn't appear. I'm fairly certain the argument I'm attempting to pass it fails because when I select "Display all results" for "Action to take if argument does not validate:" the block shows up on the page just fine. Any advice definitely appreciated.

  • UITableView with multiple selections

    - by NewDev
    I have a UITableView with multiple selections enabled. If I select items and scroll the list back and forth they are remembered and shown and selected (blue background). Using the didDeselectRowAtIndexPath and didSelectRowAtIndexPath I am able to keep my own array of selected items. That part works well. However, if I then use the sectionForSectionIndexTitle and jump to a letter, the selection appears to be forgotten - even indexPathForSelectedRows appears to have been reset and is now empty. My own array remembers that an item is selected and I can set the cell.selected in the cellForRowAtIndexPath but the instant I move the list it is forgotten again. Any ideas? Is this a bug, or how do you retain the selection list when jumping to a letter?

  • how to search for a term only in non test files

    - by dorelal
    I use ack and I like it. However from time to time I need to search for something in my code base and I want to ignore all the files residing in test directory. Basically all the files which have test in their absolute path should be not included in the search. How do I achieve that? I am willing to have a custom bash script. Something like ack_no_test "application" - search for "application" in all files but ignore files residing in test directory

  • UITextField in UITableViewCell Help

    - by W Dyson
    Hello All, I have scoured the internet looking for a good tutorial or posting about having a UITableView populated with a UITextField in each cell for data entry. I want to keep track of each UITextField and the text written within it while scrolling. The tableView will be sectioned. I have been using a custom UITableViewCell but I'm open to any method. Also, is it possible to use the textFields as ivars? If any of you could point me in the right direction, it would be greatly appreciated. Thank you in advance!

  • Service Discovery in J2ME

    - by thiagolee
    Hello, I have an application to run on a cell phone equipped with Wi-Fi and an application on a desktop which I want to communicate with. The problem is that I want to find in a Local Area Network the IP and port of the machine who has my service running. I can guarantee that there will be at maximum only one machine running it. I searched a lot for a way to do this but I ended up with nothing. I read something about WebServices, but it didn't seen to be what I wanted, what I want is really simple. I actually found a solution for it, but it can't be ported to J2ME. Anyone can help? Thanks.

  • Finding ASP.NET MVC User Control

    - by Dave
    I'm creating a custom ActionResult class and I need it to be able to operate on a UserControl. All of the examples I've found so far pass in the full path like so: return MyResult("~/ControllerName/UserControlName.ascx", myModel); But I'd like it to operate the same way as calling View(), i.e. I just pass in the name and MVC determines the correct route: return MyResult("UserControlName", myModel); Is there a way I can find out the correct route to the control without specifying it manually?

  • How can I write fast colored output to Console?

    - by Statement
    Hello world! I want to learn if there is another (faster) way to output text to the console application window using C# .net than with the simple Write, BackgroundColor and ForegroundColor methods and properties? I learned that each cell has a background color and a foreground color, and I would like to cache/buffer/write faster than using the mentioned methods. Maybe there is some help using the Out buffer, but I don't know how to encode the colors into the stream, if that is where the color data resides. This is for a retrostyle textbased game I am wanting to implement where I make use of the standard colors and ascii characters for laying out the game. Please help :)

  • How to arrange labels in a flowlayout manner?

    - by Tim Büthe
    How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

  • How to draw a filled circle in Java?

    - by Roman
    I have a JPanel with a Grid Layout. In the "cells" of the grid I can put different elements (for example JButtons). There is no problems with that. But now I want to put a filled circle in some of the cells. I also would like to relate an ActionListener with these circles. In more details, if I click the circle it disappears from the current cell and appears in another one. How can I do it in Java? I am using Swing.
