  • How to embed a google map with a changeable area?

    - by Tom
    I haven't worded this very well But basically, I'd like to embed a map on my site - but the area it shows will change. I've tried doing this, but it never seems to work as it will focus on the wrong area - the old area, rather than the new area. Basically, I'd like a google map code that uses $place as a location. Thanks.

For example, if I click button where id is array[3] so id gets value of 3 in Jquery's function. Hope you got what I mean.

  • Why the generated key size is not constant?

    - by Tom Brito
    The following code prints randomly 634, 635, 636, each time I run it. Why its not constant? public static void main(String[] args) throws Exception { KeyPairGenerator keyPairGen = KeyPairGenerator.getInstance("RSA", "BC"); keyPairGen.initialize(1024); RsaKeyPair keyPair = new RsaKeyPair(keyPairGen.generateKeyPair()); System.out.println(keyPair.getPrivate().getEncoded().length); }

  • In String.replace("\c","") what ASCII value is ""?

    - by Tom
    Hi, im just writing my own replace method for any weird characters and i used the ASCI value 0, null to replace unwanted characters, i was hoping for them to be 'deleted', but this doesnt work. A gap just appears in the string. What exactly does String.Replace() do when removing a character for ""? Does it shift them all down and then 'delete' the final character or something?

  • Eclipse Type Hierarchy Question

    - by Tom Tresansky
    In Eclipse, the Java Method Override Indicator is the little upwards arrow next to a method in the Type Hierarchy view. A solid arrow means a method overrides an existing method lower in the hierarchy. What does the hollow arrow mean? Do annotations effect either arrow?

  • A UI over Windows Workflow

    - by Tom
    Hi there, Are there any build in UI capabilities when using Windows Workflow.. Lets say I have a workflow that takes an hour to run where different activities are happening all the time. While it's running I want to see what activity is currently active, what activities have already ran etc.. Do I have to code this UI myself or does WF have built in features that graphically show the status etc of the workflow?

  • Any way to anticipate session timeout ?

    - by Tom
    Hi, Is there a way to "catch" the session timeout event, so as to retrieve data from HttpSession before its invalidated ? We're implementing the Filter Interface, and in the doFilter method, the user we stored in the session object at login is null when session times out. Thanks in advance.

    - by Tom
    Switching aged 2003 SRV to 2008 caused my Asp.net 2 application fail: The application is no more loading the required library DLL from /bin/ folder anymore. What should I change in my code or web.config to make this webapp load OK also in new 2008 server? Now I receive this error when I access the application: This type is in IMPORTS ( Dll ). Compiler Error Message: BC30002: Type 'Facebook.Entity.User' is not defined.

  • How to get the parameter names of an object's constructors (reflection)?

    - by Tom
    Say I somehow got an object reference from an other class: Object myObj = anObject; Now I can get the class of this object: Class objClass = myObj.getClass(); Now, I can get all constructors of this class: Constructor[] constructors = objClass.getConstructors(); Now, I can loop every constructor: if (constructors.length > 0) { for (int i = 0; i < constructors.length; i++) { System.out.println(constructors[i]); } } This is already giving me a good summary of the constructor, for example a constructor public Test(String paramName) is shown as public Test(java.lang.String) Instead of giving me the class type however, I want to get the name of the parameter.. in this case "paramName". How would I do that? I tried the following without success: if (constructors.length > 0) { for (int iCon = 0; iCon < constructors.length; iCon++) { Class[] params = constructors[iCon].getParameterTypes(); if (params.length > 0) { for (int iPar = 0; iPar < params.length; iPar++) { Field fields[] = params[iPar].getDeclaredFields(); for (int iFields = 0; iFields < fields.length; iFields++) { String fieldName = fields[i].getName(); System.out.println(fieldName); } } } } } Unfortunately, this is not giving me the expected result. Could anyone tell me how I should do this or what I am doing wrong? Thanks!

  • Trying to understand Java RSA key size

    - by Tom Brito
    The key generator was initilized with a size of 1024, so why the printed sizes are 635 and 162? import java.security.KeyPair; import java.security.KeyPairGenerator; import java.security.NoSuchAlgorithmException; import java.security.NoSuchProviderException; import java.security.interfaces.RSAPrivateKey; import java.security.interfaces.RSAPublicKey; public class TEST { public static KeyPair generateKeyPair() throws NoSuchAlgorithmException, NoSuchProviderException { KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA", "BC"); keyPairGenerator.initialize(1024); return keyPairGenerator.generateKeyPair(); } public static void main(String[] args) throws Exception { KeyPair keyPair = generateKeyPair(); RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate(); RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic(); System.out.println("Size = " + privateKey.getEncoded().length); System.out.println("Size = " + publicKey.getEncoded().length); } }

  • Multiple dropdowns, combination check and filter

    - by Tom
    Using Javascript / jQuery, I'm trying to build a "combination checker" that will take the values of three (but can be more) dropdown lists and filter the options based on a supplied list of allowed combinations. For example: DROPDOWNS Field 1: - value_1 - value_2 Field 2: - value_3 Field 3: - value_4 - value_5 COMBINATIONS - value_1, value_3, value_5 - value_1, value_3, value_4 - value_2, value_3, value_5 When a user selects Field 3 - value_4, the unavailable options will be disabled - ie, Field 1 - value_2 (there is no combination that allows value_2 and value_4 to be selected together). It would be really great if someone could provide some pointers on how this can be achieved or just provide a fresh perspective - I'm going round in circles on this one!

  • Android/ iOS how to determine small changes in distance using sensors?

    - by Tom
    I have been doing a bit of research, but I cannot seem to find a way to determine small distances (centimeters and meters) using the sensors in Android or iOS devices. Bluetooth appears too inaccurate and require more than one device, GPS only works over larger variations in distance, and small variations in rotation seem to make using the accelerometer nearly impossible. Is there a method that I am unaware of that would allow me to do such a thing? I am familiar with Calculus, so using Integrals to determine distance based on changes in time and velocity/ acceleration is not a problem for me, I just do not know how to determine those things. Thank you.

  • How to set Main Inerface in xCode programatically

    - by Tom Tallak Solbu
    I am using Apples MultipleDetailViews http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html for template as a source for my iPad app. The template is using a splitviewController in the interface builder (MainWindow). In the iPhone/iPad Deployment info of the target, MainWindow is set as the "Main Interface". I want my app to also run on iPhone. This means I need to load a different xib when the app is run on an iPhone. I must then remove "MainWindow" from "Main Interface" because the app will crash when I load on an iPhone due to the splitViewController. The AppDeleagte of the template look like this: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; self.window.rootViewController = self.splitViewController; [self.window makeKeyAndVisible]; } If I remove "Main Window" from "Main Interface", how do I then need to change the APpDelegate, or maybe I need to change the MainWindow.xib to also work for iPhone?

  • javascript: How to assign a function to an element.

    - by Tom
    Hi, Here's what I want: I have an element in my html code, and I want to assign a function to the onClick event, depending on some conditions to be known down the road. For example <a href="" id = "element"><img .....> //other code </a> Then I want to do something like this <logic:equals some_condition> <script> var e = document.getObjectById("element"); e.onClick = my_function(); </script> </logic> But I cant get it working. Is there any special syntax? I've tried with e.onClick = my_function; e.onClick = function(){my_function();} Sadly i'm in IE 6. Thanks in advance.

  • No such file to load, Model/Lib naming conflict?

    - by Tom
    I'm working on a Rails application. I have a Module called Animals. Inside this Module is a Class with the same name as one of my Models (Dog). show_animal action: def show_animal require 'Animals/Bear.rb' #Works require 'Animals/Dog.rb' #Fails end So the first require definitely works, the seconds fails. MissingSourceFile (no such file to load -- Animals/Dog.rb): I noticed that Dog.rb is the same file name as one of my models, is that what's causing this? I'm using Webrick.

  • XSLT; parse escaped text to a node-set and extract subelements

    - by Tom W
    Hello SO; I've been fighting with this problem all day and am just about at my wit's end. I have an XML file in which certain portions of data are stored as escaped text but are themselves well-formed XML. I want to convert the whole hierarchy in this text node to a node-set and extract the data therein. No combination of variables and functions I can think of works. The way I'd expect it to work would be: <xsl:variable name="a" select="InnerXML"> <xsl:for-each select="exsl:node-set($a)/*"> 'do something </xsl:for-each> The input element InnerXML contains text of the form <root><element a>text</element a><element b><element c/><element d>text</element d></element b></root> but that doesn't really matter. I just want to navigate the xml like a normal node-set. Where am I going wrong?

  • Android - Opening phone deletes app state

    - by Tom G
    Hey everyone, I'm writing an android application that maintains a lot of "state" data...some of it I can save in the form of onSaveInstanceState but some of it is just to complex to save in memory. My problem is that sliding the phone open destroys/recreates the app, and I lose all my application state in the process. The same thing happens with the "back" button, but I overloaded that function on my way. Is there any way to overload the phone opening to prevent it from happening? Thanks in advance.
