• Horizontal and vertical center text inside div

  - by Christophe Herreman

  I have a div with a background image that needs to be centered horizontally and vertically. On top of that image, I also want to display some text, also centered horizontally and vertically. I managed to get the image centered, but the text is not centered vertically. I thought vertical-align:middle would do the trick. Here's the code I have: <div style="background: url('background.png') no-repeat center; width:100%; height:100%; text-align:center;"> <div style="color:#ffffff; text-align: center; vertical-align:middle;" > Some text here. </div> </div> Any ideas?

• Silverlight Binding: User controls inside datagrid.

  - by Eric

  I have a DataGrid in my silverlight app that has a few columns. A couple basic columns bound with no issues. One column has a UserControl in it and the XAML is as follows: <data:DataGridTemplateColumn Header="" CanUserSort="True" Width="107"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <local:StaticPageEnlistment EnlistmentName="{Binding SiteName}" Width="400" Height="150"/> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> So I have a public property that's a string called EnlistmentName that I have bound to the SiteName value. I use this same "{Binding SiteName}" in all my other colums with no issues, why can't the user control accept the same binding string?

• Scope of variables inside of javascript

  - by wcpro

  I have the following code sample that im trying to wrap my head around $(document).ready(function () { test("load json", function () { length = 0; // length = 0 $.getJSON("plugins/form.json", function (data) { length = data.fields.length; // length = 4 }); ok(length == 4, "length = " + length.toString()); // length = 0? wtf? }); }); the 'length' variable does not persist when the $.getJSON runs. I cant figure out if its because its asynchronous or because the variable is out of scope.

• building list of child objects inside main object

  - by Asdfg

  I have two tables like this: Category: Id Name ------------------ 1 Cat1 2 Cat2 Feature: Id Name CategoryId -------------------------------- 1 F1 1 2 F2 1 3 F3 2 4 F4 2 5 F5 2 In my .Net classes, i have two POCO classes like this: public class Category { public int Id {get;set;} public int Name {get;set;} public IList<Feature> Features {get;set;} } public class Feature { public int Id {get;set;} public int CategoryId {get;set;} public int Name {get;set;} } I am using a stored proc that returns me a result set by joining these 2 tables. This is how my Stored Proc returns the result set. SELECT c.CategoryId, c.Name Category, f.FeatureId, f.Name Feature FROM Category c INNER JOIN Feature f ON c.CategoryId = f.CategoryId ORDER BY c.Name --Resultset produced by the above query CategoryId CategoryName FeatureId FeatureName --------------------------------------------------- 1 Cat1 1 F1 1 Cat1 2 F2 2 Cat2 3 F3 2 Cat2 4 F4 2 Cat2 5 F5 Now if i want to build the list of categories in my .Net code, i have to loop thru the result set and add features unless the category changes. This is how my .Net code looks like that builds Categories and Features. List<Category> categories = new List<Category>(); Int32 lastCategoryId = 0; Category c = new Category(); using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { //Check if the categoryid is same as previous one. //If Not, add new category. //If Yes, dont add the category. if (lastCategoryId != Convert.ToInt32(reader["CategoryId"])) { c = new Category { Id = Convert.ToInt32(reader["CategoryId"]), Name = reader["CategoryName"].ToString() }; c.Features = new List<Feature>(); categories.Add(c); } lastCategoryId = Convert.ToInt32(reader["CategoryId"]); //Add Feature c.Features.Add(new Feature { Name = reader["FeatureName"].ToString(), Id = Convert.ToInt32(reader["FeatureId"]) }); } return categories; } I was wondering if there is a better way to do build the list of Categories?

• Perl standard input with argument inside Bash

  - by neversaint

  I want to have such pipe in bash #! /usr/bin/bash cut -f1,2 file1.txt | myperl.pl foo | sort -u Now in myperl.pl it has content like this my $argv = $ARG[0] || "foo"; while (<>) { chomp; if ($argv eq "foo") { # do something with $_ } else { # do another } } But why the Perl script can't recognize the parameter passed through bash? Namely the code break with this message: Can't open foo: No such file or directory at myperl.pl line 15. What the right way to do it so that my Perl script can receive standard input and parameter at the same time?

• Drupal, Lightbox: cannot edit the content inside

  - by Patrick

  hi, I'm using Drupal and Lightbox module to display the content of articles in this website: donatellabernardi.ch/drupal if you click on an article the lightbox is displayed. However I have 2 problems with it: 1) I cannot use the libraries such as the tooltip library qTip from it. (If you move the mouse over the balls, you'll see the tooltips) 2) I cannot invert the title with the balls (tags), because it seems that the template of the node in the lightbox is not controlled by my theme. I tried also to change the node template (in the drupal root folder), swapping title and meta data but it didn't work. thanks

• A public struct inside a class

  - by Koning Baard

  I am new to C++, and let's say I have two classes: Creature and Human: /* creature.h */ class Creature { private: public: struct emotion { /* All emotions are percentages */ char joy; char trust; char fear; char surprise; char sadness; char disgust; char anger; char anticipation; char love; }; }; /* human.h */ class Human : Creature { }; And I have this in my main function in main.cpp: Human foo; My question is: how can I set foo's emotions? I tried this: foo->emotion.fear = 5; But GCC gives me this compile error: error: base operand of '-' has non-pointer type 'Human' This: foo.emotion.fear = 5; Gives: error: 'struct Creature::emotion' is inaccessible error: within this context error: invalid use of 'struct Creature::emotion' Can anyone help me? Thanks P.S. No I did not forget the #includes

• Checking JRE version inside browser

  - by Brian Lewis

  Basically, I'm wanting to figure out the best way to check the user's JRE version on a web page. I have a link to a JNLP file that I only want to display if the user's JRE version is 1.6 or greater. I've been playing around with the deployJava JavaScript code (http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html) and have gotten it to work in every browser but Safari (by using deployJava.versionCheck). For whatever reason, Safari doesn't give the most updated JRE version number - I found this out by displaying the value of the getJREs() function. I have 1.6.0_20 installed, which is displayed in every other browser, but Safari keeps saying that only 1.5.0 is currently installed. I've also tried using the createWebStartLaunchButtonEx() function and specifying '1.6.0' as the minimum version, but when I click the button nothing happens (in any browser). Any suggestions?

• Use of properties vs backing-field inside owner class

  - by whatispunk

  I love auto-implemented properties in C# but lately there's been this elephant standing in my cubicle and I don't know what to do with him. If I use auto-implemented properties (hereafter "aip") then I no longer have a private backing field to use internally. This is fine because the aip has no side-effects. But what if later on I need to add some extra processing in the get or set? Now I need to create a backing-field so I can expand my getters and setters. This is fine for external code using the class, because they won't notice the difference. But now all of the internal references to the aip are going to invoke these side-effects when they access the property. Now all internal access to the once aip must be refactored to use the backing-field. So my question is, what do most of you do? Do you use auto-implemented properties or do you prefer to always use a backing-field? What do you think about properties with side-effects?

• calling startActivity() inside of a instance method - causing a NullPointerException

  - by Cole

  Heya - I'm trying to call startActivity() from a class that extends AsyncTask in the onPostExecute(). Here's the flow: Class that extends AsyncTask: protected void onPostExecute() { Login login = new Login(); login.pushCreateNewOrChooseExistingFormActivity(); } Class that extends Activity: public void pushCreateNewOrChooseExistingFormActivity() { // start the CreateNewOrChooseExistingForm Activity Intent intent = new Intent(Intent.ACTION_VIEW); **ERROR_HERE*** intent.setClassName(this, CreateNewOrChooseExistingForm.class.getName()); startActivity(intent); } And I get this error… every time: 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): FATAL EXCEPTION: main 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): java.lang.NullPointerException 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at android.content.ContextWrapper.getPackageName(ContextWrapper.java:120) 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at android.content.ComponentName.(ComponentName.java:62) 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at android.content.Intent.setClassName(Intent.java:4850) 03-17 16:04:29.579: ERROR/AndroidRuntime(1503): at com.att.AppName.Login.pushCreateNewOrChooseExistingFormActivity(Login.java:47) For iOS developers - I'm just trying to push a new view controller on to a navigational controller's stack a la pushViewController:animated:. Which apparently - is hard to do on this platform. Any ideas? Thanks in advance! UPDATE - FIXED: per @Falmarri advice, i managed to resolve this issue. first of all, i'm no longer calling Login login = new Login(); to create a new login object. bad. bad. bad. no cookie. instead, when preparing to call .execute(), this tutorial suggests passing the applicationContext to the class the executes the AsyncTask, for my purposes, as shown below: CallWebServiceTask task = new CallWebServiceTask(); // pass the login object to the task task.applicationContext = login; // execute the task in the background, passing the required params task.execute(login); now, in onPostExecute(), i can get to my Login objects methods like so: ((Login) applicationContext).pushCreateNewOrChooseExistingFormActivity(); ((Login) applicationContext).showLoginFailedAlert(result.get("httpResponseCode").toString()); ... hope this helps someone else out there! especially iOS developers transistioning over to Android...
