Mr. A — Fri, 23 Mar 2012 19:26:26 +0000

Actually this is because Objects are cached. You can refresh cache using

Edit -> Intellisense -> Refresh Local Cache (CTRL+Shift+R)

Creating “Rate This App” link for iPhone/iPad

Mr. A — Mon, 06 Jun 2011 01:37:51 +0000

You can add the following link to your app to redirect users to the “Write A Review” section for your app:

http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=353432042&pageNumber=0&sortOrdering=1&type=Purple+Software&mt=8

Just replace the id parameter of the url with your app’s id.

Parallelizing Windows Applications in .NET 4.0

Mr. A — Fri, 20 May 2011 19:31:05 +0000

I needed to create different threads for a foreach loop and found this great article: http://dotnet.dzone.com/articles/parallelizing-windows

var magicString =string.Empty;
var list = new List&lt;string&gt; {".NET", "Zone"};

Parallel.ForEach(list, oneString =>;

{

magicString += oneString;

});

Excluding unnecessary files from the build and publishing

The E — Wed, 02 Mar 2011 22:41:42 +0000

I dont know whether to feel proud or disappointed about this one. For the past four years I have published my site from Visual Studios 2005 way over a thousand times because of updates or whatnot. Every time it would take anywhere from 10 to 15 minutes. Today I decided to do something about it…FOUR YEARS LATER! I found out that there is a property you can set in your web.config folder that will define the extensions you would like the compiler to ignore when building and publishing your site. My publishing is now taking a whopping 1 minute. I will stick the example that microsoft used, which ignores .doc, .psd, and .vsd files, as well as the source link.

  
          type="System.Web.Compilation.IgnoreFileBuildProvider" /> 

          type="System.Web.Compilation.IgnoreFileBuildProvider" />

Rails: Using uncached

Mr. A — Mon, 21 Feb 2011 17:05:00 +0000

I need to retrieve some data from my DB but I have caching turned on in my rails app. After doing some research, I found that you can call uncached and it will ignore the cache.

Example:

def test_action

     ActiveRecord::Base.connection.uncached do

          job = Workflow.find(10911)

          job = Workflow.find(10911)

          job = Workflow.find(10911)

     render :xml => job.to_xml(:skip_types => true, :dasherize => false, :camelize => true)

     end

end

When Visual Studios quits debug mode right after debug start on an ASP.net application

The E — Thu, 27 Jan 2011 17:22:06 +0000

This is a problem that was coming and going for me and every time I figured it out I was content and moved on with my life, but then it happened to me again months later and I forgot the solution, hence this post. What would happen was that when I pressed debug on an asp.net application the browser would pop up correctly but in visual studios the debugger would turn off, as if it was set to auto stop debug on start. Pretty much whenever this happens what you have to do is to make sure the web server and the browser that ran the application, in this case internet explorer are off. To make sure this is implemented I do it through the task manager.

Mimicking a HashTable in ASP by using the Dictionary Object

The E — Wed, 26 Jan 2011 16:32:12 +0000

So I needed to imitate the functionality of a hashtable in asp. I needed a number and name key/value pair so that I could loop through them and display them in a select box. Using an array wont work of course since you can only display one value, unless the index of the array is the second value (or first value, you know what I mean). Using the dictionary object allows you to pair two values together just like the good ole’ hashtable that our friendly neighborhood languages offer.

<%
dim d,a,b,i
set d=Server.CreateObject("Scripting.Dictionary")

d.Add"n","Norway"

d.Add"i","Italy"

d.Add"s","Sweden"
Response.Write("
Key values:
")

a=d.Keys

b=d.Items
for i=0 to d.Count-1
Response.Write(a(i)&", "& b(i))
Response.Write("
")
next
set d=nothing

%>

Capturing iPhone/iPad Screenshots from Xcode Simulator

Mr. A — Sat, 22 Jan 2011 14:53:58 +0000

While trying to submit our iPad app Let’s Multiply. We found an easy way to capture screenshots of the iPad/iPhone Simulator. All you have to do if hit Control + Command + C. This will capture the screenshot and copy it to the clipboard, just paste and save the image in any image editor.
For the iPad, make sure that you you Scale the Simulator to 100% (It will capture the whole iPad screen even if the simulator screen doesn’t fit on your monitor)
