• Actionscript blur/shadows/glows how heavy are they on the processor?

  - by Fahim Akhter

  Hi, I have say 10 items in a particular space, If I apply glows and drop shadows to all of them and all of these items are usually static. Other characters do move around them too. So I'm just wondering would it be wise to use vectors with actionscript blurs and glows. Or to have a PNG? and if I cannot have a PNG and have to work with vectors with glows/blurs/shadows. Would they be too heavy on the processor?

• How to use UIWebView to get scrolling text ?

  - by srikanth rongali

  Hi, In my iPhone application I need a scrolling text. I had the text to be displayed and scrolled up and down but I could not get customized text. I mean all the text is of same font. I need some different font size text . I am using UITextView, but UITextView do not support customized text in it. How can I have the scrolling text which has different font size. I read that to use UIWebView for this. But, I could not understand how to use it. the text contains no url's no editing.(It need to be just static text to read). How can I do this ? Thank you.

• I have a problem with the following Java code

  - by Sanjeev

  public class b { public static void main(String[] args) { byte b = 1; long l = 127; // b = b + l; // 1 if I try this then it does not compile b += l; // 2 if I try this then it does compile System.out.println(b); } } I am using this code but I have problem: I don't understand why b=b+l; is not compiling but if I write b+=l; then it compiles and runs. Please explain why this happens.

• WF4RC, How to: Activity to Xaml?

  - by johnny g

  Hello all, I have Googled a bit, and cannot seem to find any examples of Xaml-fying Activities - good, bad, or otherwise! public static string ToXaml (this Activity activity) { // i would use ActivityXamlServices to go from Xaml // to activity, but how to go other way? documentation // is slim, and cannot infer proper usage of // ActivityXamlServices from Xml remarks :S string xaml = string.Empty; return xaml; } Hints, tips, pointers would be welcome :) NOTE: so found this. Will work through and update once working. Anyone wanna beat me to the punch, by all means. Better yet, if you can find a way to be rid of WorkflowDesigner, seems odd it is required.

• Create IEnumerable<T>.Find()

  - by Brian

  I'd like to write: IEnumerable<Car> cars; cars.Find(car => car.Color == "Blue") Can I accomplish this with extension methods? The following fails because it recursively calls itself rather than calling IList.Find(). public static T Find<T>(this IEnumerable<T> list, Predicate<PermitSummary> match) { return list.ToList().Find(match); } Thanks!

• Accessing a Clip Inside Another Clip in a Loaded SWF-File

  - by Anders

  I'm writing a card game in AS3. The artist I'm working with has produced (in Flash CS4) a single swf-file containing all the card graphics and animations. The structure of the fla working file looks something like this: - Scene - CardGraphics (Movie Clip) - CardFront - CardBack - CardValueImage (Movie Clip) ... In the program I create 52 instances of my Card class, each having a MovieClip instance created from the loaded swf. The idea is to set the frame of the CardValueImage MovieClip to correspond to the Card instance's suit and rank member variables. However, I can't figure out how I access CardValueImage and call gotoAndStop (or whatever method I will need to call). This is basically what I want to do: // Card Class [Embed(source = 'CardGraphics.swf')] private static var CardsClip:Class; private var clip:MovieClip = new CardsClip; // Card Constructor this.valueImageFrame = suit * 13 + rank; // Calculate which frame contains the // graphical representation of this card this.clip.CardValueImage.gotoAndStop(valueImageFrame);

• Strange Error - "Object moved to here."

  - by Dkong

  I get the strange error "Object moved to here." on a blank white page when I try to login on a site I created. It works fine locally but not when I deploy it to the test or production server. I am not doing anything odd, just using basic authentication code in a helper function as follows... public static bool AuthenticateUser(string Username, string Password, bool PersistLogin, string RedirectionURL) { if (Membership.ValidateUser(Username, Password)) { FormsAuthentication.SetAuthCookie(Username, PersistLogin); HttpContext.Current.Response.Redirect(RedirectionURL,true); return true; } else return false; }

• C# StringBuilder question

  - by andrew

  in a C# file i have a class Archiver { [DllImport("Archiver.dll")] public static extern void archive(string data, StringBuilder response); } string data is an input, and StringBuilder response is where the function writes something the archive function prototype (written in C) looks like this: void archive(char * dataChr, char * outChr); and it receives a string in dataChr, and then does a strcpy(outChr,"some big text"); from C# i call it something like this: string message = "some text here"; StringBuilder response = new StringBuilder(10000); Archiver.archive(message,response); this works, but the problem, as you might see is that i give a value to the StringBuilder size, but the archive function might give back a (way) larger text than the size i've given to my StringBuilder. any way to fix this?

• UITableView - iPad - Property '' Not Found on Object of type UITableViewCell

  - by user1797508

  I have added a UITableView prototype Cell into a UIView for an iPad application using StoryBoard in Xcode (targeting iOS6). The problem I'm having is that the labels are not being recognized in my viewController when I try to reference them. In my implementation, I have: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"dashboardMessage"; UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } int row = [indexPath row]; cell.messageSender.text = [_matches valueForKey:@"from"]; } The last line is causing an error: Property 'messageSender' Not Found on Object of type UITableViewCell In the cell's header file I have: @interface DashboardMessageCell : UITableViewCell @property (strong, nonatomic) IBOutlet UILabel *messageSender; @property (strong, nonatomic) IBOutlet UILabel *messageDescr; and the header file is imported into the viewController. I'm lost as to what can be causing the issue, any help would be greatly appreciated. Thanks.

• Are there any PHP Frameworks (e.g. CodeIgniter) that support database connections on a per user acco

  - by Brad G

  I'm looking into developing a multi-tenant SaaS application, and I found several sites that describe a solid way to separate the data using tenantIDs and updateable views. e.g. This blog post It all hinges on the ability to have your user accounts authenticated from a master users table and then having their respective database connections use those user-specific credentials. This way, the views can pull the userid and map it to the tenantID to display that user's view. However, most PHP frameworks tend to be very static when it comes to database connections (stored in text config files). They appear to be at odds. Does anyone know: a) how to make CodeIgniter handle this gracefully? b) a different PHP framework that might?

• XSLT 1.0: Sorting by concating portions of date string

  - by dscl

  I'm trying to take XML data and sort elements by their data attribute. Unfortunately the dates come over in mm/dd/yyyy format and are not static lengths. (Jan = 1 instead of 01) So I believe the string will have to be parsed into three components and the month padded. The newly concated value (yyyymmdd) then sorted descending. Problem is I have no idea how to do this. Here is an example of the data <content date="1/13/2011 1:21:00 PM"> <collection vo="promotion"> <data vo="promotion" promotionid="64526" code="101P031" startdate="1/7/2011 12:00:00 AM"/> <data vo="promotion" promotionid="64646" code="101P026" startdate="2/19/2011 12:00:00 AM"/> <data vo="promotion" promotionid="64636" code="101P046" startdate="1/9/2011 12:00:00 AM"/> </collection> </content> Also can anyone please recommend a good book on learning XSLT? Thanks!

• Add up values from a text file

  - by Stanley

  Hi Guys I have a text file that contains Amounts at Substring (34, 47) of each line. I need to sum Up all the Values to the End of the File. I have this code that I had started to build but I do not know how to proceed from here: public class Addup { /** * @param args the command line arguments */ public static void main(String[] args) throws FileNotFoundException, IOException { // TODO code application logic here FileInputStream fs = new FileInputStream("C:/Analysis/RL004.TXT"); BufferedReader br = new BufferedReader(new InputStreamReader(fs)); String line; while((line = br.readLine()) != null){ String num = line.substring(34, 47); double i = Double.parseDouble(num); System.out.println(i); } } } The output is like this: 1.44576457E4 2.33434354E6 4.56875685E3 The Amount is in two decimal Places and I need the result also in the Two decimal Places. What Is the Best way to achieve this?

• Making your own "int" or "string" class

  - by amerninja13

  I disassembled the .NET 'System' DLL and looked at the source code for the variable classes (string, int, byte, etc.) to see if I could figure out how to make a class that could take on a value. I noticed that the "Int32" class inherits the following: IComparable, IFormattable, IConvertible, IComparable, IEquatable. The String and Int32 classes are not inheritable, and I can't figure out what in these inherited interfaces allows the classes to hold a value. What I would want is something like this: public class MyVariable : //inherits here { //Code in here that allows it to get/set the value } public static class Main(string[] args) { MyVariable a = "This is my own custom variable!"; MyVariable b = 2976; if(a == "Hello") { } if(b = 10) { } Console.WriteLine(a.ToString()); Console.WriteLine(a.ToString()); }

• Lucene .NET IndexWriter lock

  - by Pini Salim

  My question related to the next code snippet: static void Main(string[] args) { Lucene.Net.Store.Directory d = FSDirectory.Open(new DirectoryInfo(/*my index path*/)); IndexWriter writer = new IndexWriter(d, new WhitespaceAnalyzer()); //Exiting without closing the indexd writer... } In this test, I opened an IndexWriter without closing it - so even after the test exits, the write.lock file still exists in the index directory, so I expected that the next time I open an instance of IndexWriter to that index, a LockObatinFailedException will be thrown. Can someone please explain to me why am I wrong? I mean, does the meaning of the write.lock file is to protect creation of two IndexWriters in the same process only? that doesnt seems the right answer to me...

• Overriding a method in statically created objects

  - by I82Much

  All, Due to a bug in a library I'm using, I need to override the dispose() method on all objects extending a certain class and make it a NO-OP. I know that if I'm making new instances of the classes directly, this is easy to do: layerManager = new LayerManagerLayer(wwd) { @Override public void dispose() {} }; The problem is that a lot of the object instances I get are not directly constructed by my client code, but instead are created via static library method calls. // Here I want to override the dispose method, but I cannot. Layer l = ShapefileLoader.makeShapefileLayer(this.getClass().getResource("polylines10.shp")); Is there a way I can inject my dispose method into that statically created object without modifying the original sourcecode?

• Why does GetTextFace always return "system"?

  - by user545142

  I am trying to get the font of controls in other applications. When I try WM_GETFONT, it returns 0. This my code: [DllImport("User32.DLL")] public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); IntPtr fx = SendMessage(button1.Handle, 0x31, 0, 0); When I use GetTextFace with a button, it always returns "system". This is my code: StringBuilder Buff = new StringBuilder(256); IntPtr dc = GetDCEx(button1.Handle, IntPtr.Zero, DeviceContextValues.Window |DeviceContextValues.Cache | DeviceContextValues.ClipSiblings | DeviceContextValues.IntersectRgn); IntPtr hfont = GetTextFace(dc, 256, Buff); Of course I'm sure I changed the font type. How can I solve this problem? I am using C# under Windows 7.

• Is my program taking too much time to execute?

  - by Conrad C

  I wanted to solve a question from project euleur about finding the largest prime number of a big number. I run my code on a virtual machine on Visual studio 2012, and the code seems froze. When I step into the loop, the code works well, but when I execute it, the console is always there. It is as if the program is still running. Could it be that the program takes time to execute? My Code static void Main(string[] args) { long number = 5; for (long i = 1; i < 600851475143; i++) { if (i % 2 != 0 && i % 1 == 0 && i % i == 0) number = i; } }
