• How can I create numbered map markers in Google Maps V3?

  - by kaneuniversal

  I'm working on a map that has multiple markers on it. These markers use a custom icon, but I'd also like to add numbers on top. I've seen how this has been accomplished using older versions of the API. How can I do this in V3? *Note -- the "title" attribute creates a tooltip when you mouseover the marker, but I want something that will be layered on top of the custom image even when you're not hovering on top of it. Here's the documentation for the marker class, and none of these attributes seem to help: http://code.google.com/apis/maps/documentation/v3/reference.html#MarkerOptions Thank you . . . . Michael

• Simple Emacs keybindings

  - by User1

  I have two operations that I do all the time in Emacs: Create a new buffer and paste the clipboard. [C-S-n] Close the current buffer. [C-S-w] Switch to the last viewed buffer [C-TAB] I feel like a keyboard acrobat when doing the first two operations. I think it would be worth trying some custom keybindings and macros. A few questions about this customization: How would I make a macro for #1? Are these good keybindings (i know this is a bit subjective, but they might be used by something popular that I don't use) Has anyone found a Ctrl-Tab macro that will act like Alt-Tab in Linux/Windows? Specifically, I want it have a stack of buffers according to the last viewed timestamp (most recent on top). I want to continue cycling through the stack until I let go of the ctrl key. When the ctrl key is released, I want the current buffer to get an updated position on the stack.

• JQuery click event, not working

  - by Roland

  I have the following scenario. I have a index.php page with the following JQuery code included jQuery(document).ready(function(){ jQuery('#sIMG img').click(function(){ var currentSRC = jQuery(this).attr('src'); var altSRC = jQuery(this).attr('title'); var imgID = jQuery(this).attr('id'); var cat = jQuery(this).attr('name'); /*Fade, Callback, swap the alt and src, fade in */ jQuery('#main').fadeOut('fast',function(){ jQuery('#main').load("detail.php?id="+imgID+"&category="+cat); jQuery('#main').fadeIn('fast'); }); }); }); Now I have two div tags called #main and #right in the index.php page. When I click on a menu item right changes to a bunch of images, if I click on one of those images the above code should take effect and load into the main div, but it's just not working. the images are located within a div called sIMG. Any help will be appreciated

• Ria Services loading foreign keys with Linq-to-SQL

  - by Stephan

  I have a database that consists of 5 tables : Course, Category, Location, CourseCategories, and CourseLocations. The last 2 tables just contain the two foreign keys. A Course has many-to-many relationships with both category and location. I am trying to load the data into a Silverlight app using Ria Services. My DB model is Linq-to-SQL. I have tried adding the [Include] attribute to the metadata classes and I have added the DataLoadOptions so it should load the all tables when you ask for a Course. However on the client side I am never getting back any entries in the CourseCategories and CourseLocations properties. What else needs to be done to get the foreign key relationships to exist across the serialization.

• Simple javascript document.write isn't working...

  - by Jascination

  Here's the code in question I'm trying to create a simple application - each of the three men has a rel="x" attribute attached them. I'm using var regionId = $('img.selected-region').attr('rel'); to make the rel of the currently selected item the value of reginId. I want to test this out by performing a simple document.write(regionId) command in a div under the pictures of the men. However, it's not working. Have I put the var regionId definition in the right place in the script window? I'm completely new to javascript so the syntax is confusing to me - and help would be greatly appreciated.

• Self-referential ReferenceProperty in Google App Engine

  - by Ink-Jet

  I'm having a bit of trouble with ReferencePropertys in App Engine (Python). For a bit of fun, I'm trying to model a folder/file system, but having trouble getting folders to reference folders. My first attempt was this: class Folder(db.Model): id = db.StringProperty() name = db.StringProperty() created = db.DateTimeProperty(auto_now_add=True) folder = db.ReferenceProperty(Folder, collection_name="folders") But that fails as "Folder" isn't defined when "folder" is trying to be defined. I've also tried defining "folder" outside of the main declaration for "Folder", like so: class Folder(db.Model): id = db.StringProperty() name = db.StringProperty() created = db.DateTimeProperty(auto_now_add=True) Folder.folder = db.ReferenceProperty(Folder, collection_name="folders") But that fails with: AttributeError: 'Folder' object has no attribute 'folders' I'm kind of stumped. Does anyone have experience with this, or a solution to this problem? Thanks in advance.

• JSTL XML Transforms not working with nested XSL includes

  - by timxyz

  I have a bit of JSP that does this: <c:import url="/xsl/Transformer.xsl" var="xslt" /> <x:transform doc="${actionBean.dom}" xslt="${xslt}" xsltSystemId="/xsl/"> This transforms the XML exactly as expected so long as Transformer.xsl contains no <xsl:include> tags or so long as any documents it does include do not include anything. However, if I use an XSL which includes a document which in turn includes another document, I get the following error: ERROR: 'Invalid URI 'NestedInclude.xsl Could not resolve entity reference: "NestedInclude.xsl"'.' Note that the JSP is contained in the directory below the xsl documents. If all my XSLs and JSPs are in the same directory (and I remove the xsltSystemId attribute) then everything would work fine, but I don't really want to do this. Can anyone see anything I'm doing wrong, as it's a bit of a killer at the moment and the JSTL documentation is next to useless.

• Do I still have to implement a singleton class by hand in .net, even when using .Net4.0?

  - by Hamish Grubijan

  Once the singleton pattern is understood, writing subsequent singleton classes in C# is a brainless exercise. I would hope that the framework would help you by providing an interface or a base class to do that. Here is how I envision it: public sealed class Schablone : ISingleton<Schablone> { // Stuff forced by the interface goes here // Extra logic goes here } Does what I am looking for exist? Is there some syntactic sugar for constructing a singleton class - whether with an interface, a class attribute, etc.? Can one write a useful and bullet-proof ISingleton themselves? Care to try? Thanks!

• ASP.NET MVC 2: Data DataAnnotations validation be convention

  - by stacker

  I have a required attribute that used with resources: public class ArticleInput : InputBase { [Required(ErrorMessageResourceType = typeof(ArticleResources), ErrorMessageResourceName = "Body_Validation_Required")] public string Body { get; set; } } I want to specify the resources be convention, like this: public class ArticleInput : InputBase { [Required2] public string Body { get; set; } } Basically, Required2 implements the values based on this data: ErrorMessageResourceType = typeof(ClassNameWithoutInput + Resources); // ArticleResources ErrorMessageResourceName = typeof(PropertyName + "_Validation_Required"); // Body_Validation_Required Is there any way to achieve something like this? maybe I need to implement a new ValidationAttribute.

• Removing the Default Wrap Character From all records

  - by aceinthehole

  I am using BizTalk 2009 and I have a flat file that is similar to the following "0162892172","TIM ","LastName ","760 "," ","COMANCHE ","LN " "0143248282","GEORGE ","LastName ","625 "," ","ENID ","AVE " When I parse it and start mapping it I need to get rid of the quotation marks. I have marked the Wrap Character attribute for the schema as a quotation mark but it doesn't remove it when BizTalk is parsing the file. Is there an easy way to specify the removal of a wrap character or am I going to have to run it through a script functiod every time? Also I would like to be able to remove the trailing spaces as well, if at all possible.

• DllImport Based on OS Platform

  - by Ngu Soon Hui

  I have a mixture of unmanaged code ( backend) and managed code ( front end), as such, I would need to call the unmanaged code from my managed code, using interop techniques and DllImport attribute. Now, I've compiled two versions of unmanaged code, for both 32 and 64 bit OS; they are named service32.dll and service64.dll respectively. So, in my .Net code, I would have to do a DllImport for both dlls: [DllImport(@"service32.dll")] //for 32 bit OS invocation public static void SimpleFunction(); [DllImport(@"service64.dll")] //for 64 bit OS invocation public static void SimpleFunction(); And call them depending on which platform my application is running on. The issue now is that for every unmanaged function, I have to declared it twice, one for 32 bit OS and one for 64 bit OS. This is a duplication of work, and everytime I change the signature of an unmanaged function, I have to modified it in two places. Is there anyway that I can change the argument in DllImport so that the correct dll will be invoked automagically, depending on the platform?

• Is this __import__ functionality correct?

  - by Jason Baker

  I have a package named jiva_tasks, which I'm trying to import via celery (using the CELERY_IMPORTS attribute of celeryconfig. The import statement that celery is using is this: __import__(module, [], [], ['']) Oddly enough, when this syntax is used, the module gets imported twice, once as jiva_tasks and another time as jiva_tasks. (with a period at the end). Now, chances are good that celery should be passing in globals rather than an empty list, but this seems broken to me. It seems odd that even if given the wrong arguments, __import__ would import something that isn't a valid python module name. I know that the way to fix this is to pass in globals, but I want to understand why I'm getting this result. Is this a bug, or is there something I don't understand about how __import__ is working? Update: It also seems to be working fine if I use importlib.

• Recursively listing, and storing, directory contents

  - by enchilada

  I know how to recursively list directory contents. I will be using Snow Leopard's enumeratorAtURL:includingPropertiesForKeys:options:errorHandler: method to do this. However I want to store my findings into a object hierarchy (of, say, objects of a custom FileOrDirectory class that has isLeaf, children, and count attributes). I need to pre-load the directory and file structure into such a object hierarchy, in order to do whatever I want with NSTreeController and whatnot. I guess the trickiest thing here is to get the children attribute correct in the object hierarchy. Any ideas?

• Gracefully avoiding NullPointerException in Java

  - by Yuval A

  Consider this line: if (object.getAttribute("someAttr").equals("true")) { // .... Obviously this line is a potential bug, the attribute might be null and we will get a NullPointerException. So we need to refactor it to one of two choices: First option: if ("true".equals(object.getAttribute("someAttr"))) { // .... Second option: String attr = object.getAttribute("someAttr"); if (attr != null) { if (attr.equals("true")) { // .... The first option is awkward to read but more concise, while the second one is clear in intent, but verbose. Which option do you prefer in terms of readability?

• Disable link with the prototype observe method...

  - by enyo

  I want to create a link like this: <a href="http://example.com">text</a> and replace the behavior so that the link downloads the content with Ajax instead when clicking. It is important for me not to replace the href attribute (so copying the link still works). One solution would be to do: $('link').onclick = function() { return false; }; but I would like to use the .observe method. But this doesn't work: $('link').observe('click', function() { return false; }); (which is quite logical). Any ideas on how I could achieve this? Thanks.

• Dynamically find the parameter to be passed as <T> to a generic method

  - by Codex

  A generic method is defined as follows: private static T GetComparisonObject<T>(ComparisonAttribute attribute, object objectToParse) { // Perform a some action return (T)resultObject; } The method is invoked as follows: var srcObjectToCompare = GetComparisonObject<DynamicType>(attributeToCompare, srcObject); The type for which the method needs to be invoked is configured in the config file as: <add attributename ="Count" attributetype ="MemberInformation" attributeparam ="Count" type="System.Int32" comparertype="ditCreditEMGTestAutomationDifferenceEngine.Comparers.TypeComparer, ditCreditEMGTestAutomationDifferenceEngine.dll" /> The token that is passed in < for the generic methods has to be the type for which the method is being invoked. From the type key configuration in the XML, an instance of Type represnting the type can be created{i.e. Type.GetType("System.Int32")}, but how can the Type Definition be generated which can then be passed to the the Generic method? Hope am not missing something elementary here!! :-O Thanks in advance.

• Add HTML Id's to tags in .aspx file

  - by slandau

  So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to. Then they click start, and this runs private void btnStart_Click(object sender, EventArgs e) { for (int i = 0; i < listFiles.CheckedItems.Count; i++) { } } It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the id="thisItemId" attribute to each tag that's like a , , , , , etc....

• .NET security: how to check if a method is allowed to execute under current user's perrmissions

  - by Gart

  Given an ASP.NET MVC Controller class declaration: public class ItemController : Controller { public ActionResult Index() { // ... } public ActionResult Details() { // ... } [Authorize(Roles="Admin, Editor")] public ActionResult Edit() { // ... } [Authorized(Roles="Admin")] public ActionResult Delete() { // .. } } I need to reflect a list of methods in this class which may be invoked with the current user's permissions. The [Authorized] attribute is specific to ASP.NET MVC, and this is only an example. I would prefer a universal solution for this problem which works for any .NET class. Please share some ideas of what could be done in this case.

• IE - Color transparent not working

  - by poru

  Hello, I have a problem with the IE (what else?): I generate content with CSS which has also a background-image. I looks like that: #nav ul li:after { content: "--"; position: relative; z-index: 99; background: transparent url(image.png); color: transparent; } The text color is in non-IE-browsers transparent, but in all IE browsers it's black and you could see it. How could I make the text transparent/unvisible? I tried already: visibility - opacity - filter - text-indent ... But none did his job right, either it disappears (with it background which I need) or the attribute doesn't apply.

• How to specify a JRE range in jnlp file?

  - by vicky21

  We have a java app which uses Java Web Start. The jnlp file is configured with [j2se version="1.5+"]. So if JRE 1.5 and 1.6 are installed, the app is run on 1.6. Now, we have requirement where the app should be restricted to run only within the range - JRE 1.5.0_07 through JRE 1.5.0_17 [j2se version="1.5*"] will not work - it will always launch the app with the latest jre from 1.5 family. I can request an exact product version by including the href attribute. [j2se version="1.5.0_14" href="http://java.sun.com/products/autodl/j2se"/] But how do I specify a specific range of JREs in the jnlp file so that JWS picks up a JRE from that range only? So if 1.5.0_07, 1.5.0_17 and JRE 6 are installed, it should run the app on 1.5.0_17. Is there a good way to accomplish this?

• Javascript parent page redirection from iframe.

  - by Danil

  Hello to all. I need to implement parent page redirection from iframe. I know that it is impossible to do in different domains due to browsers security. However I found that links have target attribute and tried to use it in the following way: <a href="http://google.com" target="_top" id="testParentRedirect">someLink</a> It works fine if I click this link manually, but I couldn't find cross-browser solution to simulate it using javascript. document.getElementById('testParentRedirect').click(); This works fine in IE, however Firefox and Safary don't know click function :). I tried to work with jquery, but for some reason they don't simulate click event for links. (see following post) I couldn't find any appropriate solution on stackoverflow. Maybe someone could help me in it. I will appreciate it. :)

• Custom Web Control - ParseChildren & Resource Objects

  - by Raybiez

  I hope someone can help me. I have the following custom server control: [ParseChildren(true)] public class MyControl : WebControl, INamingContainer { [PersistenceMode(PersistenceMode.InnerProperty)] public string MyProperty { get;set; } } It works perfectly with the following mark-up: <acme:MyControl runat="sever"> <MyProperty>Test String</MyProperty> </acme:MyControl> But if I try to localise the property string, I get a parse error: <acme:MyControl runat="sever"> <MyProperty><%=(string)GetLocalResourceObject("MyResourceKey") %></MyProperty> </acme:MyControl> Even if I cast the type, ASP.NET indicates that the property cannot accept controls as children. How should the expression look like if I want to localise it? I can make the property accessible as an attribute of the control's tag, but I prefer the mark-up above, it looks more elegant and clean. Thanks

• Server-side validation and form action

  - by phenry

  I have a page (call it form.php) with a form for users to fill out. When the form is submitted, I want to validate it with a server-side script (call it validate.php if necessary, although the code could also go in one of the other pages if that would be better). If any part of the form fails validation, I want to kick back to form.php with the fields the user needs to fix highlighted. If the form passes validation, I want to go to another page, success.php. Which page should I put in the "action" attribute of the <form> element, and what's the best way to get from that page to one of the others?
