Visual Studio Tip: Reference files in Project Directory.

Lars Hundebøl — Sat, 24 Apr 2010 07:47:00 GMT

Here is a nice little tip to reference files located in Visual Studio project directory, when running the project from within Visual Studio.

Use the following code:

string path = Path.Combine(Environment.CurrentDirectory, 
  @"..\..\Test.xml");

Using doskey macrofile to optimize work within the Command Prompt

Lars Hundebøl — Wed, 02 Dec 2009 13:59:00 GMT

The following is helpfull little tip to create shortcuts to commonly used applications when working in the command prompt.

1. Create a new doskey macrofile (e.g. notepad c:\doskey)
2. Edit doskey macrofile to include all your shortcuts:

sub="C:\Program Files\Sublime Text\sublimetext.exe" $*
ie="C:\Program Files\Internet Explorer\iexplore.exe"

3. Change cmd.exe shortcut to include the following doskey command:

%SystemRoot%\system32\cmd.exe /k doskey /macrofile=c:\doskey

Relevant doskey links:

Reminder to self: How to use ASP.NET AJAX PageMethods

Lars Hundebøl — Wed, 10 Jun 2009 13:45:00 GMT

I keep forgetting how to use the ASP.NET AJAX PageMethods (.NET 3.5), so here is a short examples that gets me up to speed:

In Default.aspx.cs insert the following static method declared with the WebMethod attribute:

[WebMethod]
public static Person DoSomethingServerSide(
  string name, string email)
{
  Person p = new Person()
  {
    Name = name,
    Email = email
  };

  return p;
}

...and in the Default.aspx insert some JavaScript that leverage this PageMethod:

function DoSomethingClientSide()
{
  PageMethods.DoSomethingServerSide(
    "Test", "test@test.com", Callback);
}

function Callback(res)
{
  alert(res.Name + " " + res.Email);
}

And that's it... no wonder I keep forgetting how easy it is.

Installing Ruby on Rails on Windows with SQLite

Lars Hundebøl — Sun, 26 Apr 2009 09:12:00 GMT

The following is a step-by-step guideline to how I installed Ruby On Rails for Windows with SQLite as the database.

Download the latest version of Ruby One-Click installer for Windows here, and run the installer. This will install Ruby (naturely) and RubyGems, the package manager for Ruby.

At the time of writting this tutorial, I downloaded and installed Ruby-186-26 (stable).
Update RubyGems by executing the following line in a command prompt:
```
gem update --system
```
Now install Rails using RubyGems, by executing the following line in a command prompt:
```
gem install rails --include-dependencies
```
This will install Rails and all relevant dependencies. Please note that this may take some time to install.
Download the lastest SQLite from here, and unzip it into the Ruby bin directory (by default c:\ruby\bin). You'll only need the pre-compiled DLL; at the time of writing, the version I downloaded and unzipped was sqlitedll-3_6_13.zip.
Finally install SQLite3-Ruby using RubyGems, by executing the following line in a command prompt:
```
gem install sqlite3-ruby -v 1.2.3
```
By the time of writing version 1.2.3 was the latest version actually working with Windows.

I've used the installation guideline on Windows Vista and Windows 7 (Build 7000) without any problems. The latest version of Ruby on Rails is preconfigured to use SQLite, and therefore no additional configuration is required after creating a new rails project.

Old School Google

Back in the days, Google was a little more primitive.

SketchFlow - prototyping by Microsoft

Lars Hundebøl — Fri, 20 Mar 2009 16:18:00 GMT

At MIX 09 this week, Microsoft released the prototyping tool SketchFlow. SketchFlow allows the designer, to "sketch" up a simple prototype, using a combination of flow diagrams and hand drawn pictures or controls that looks hand drawn.

By using Silverlight, SketchFlow can create a prototype that easily can be shared with the client using the Web, and with annotating tools, the client can comment on different aspects of the prototype.

In that the prototype is a Silvelight application, it is also possible to use animations, within the prototype, to better illustrate different transition within the proposed application. There is also the added benefit of using this tool when developing Silverlight and WPF applications, it that the prototype can easily be used as the base for the actual implementation (check out the MIX 09 day 1 keynote).

Not knowing existing prototyping tools, I can't say whether or not this product is all that different from existing prototyping tools. The SketchFlow will be able for preview later this yaer.

Silverlight 3 - the morning after

Lars Hundebøl — Thu, 19 Mar 2009 16:37:00 GMT

In all my excitement yesterday, I forgot some of the crucial items on my personal wish list for Silverlight, which still is not supported by Silverlight 3. Unfortunately there is no support for webcams or microphones, as there is in Flash, and most regrettably there is no support for printing.

Microsoft said they working hard to get support for printing, so hopefully we might see this in the RTM release of Silverlight 3.

SuperPreview

Lars Hundebøl — Thu, 19 Mar 2009 16:17:00 GMT

Yesterday Microsoft announced the SuperPreview feature as part of Expression Web and as a standalone install. The cool thing about SuperPreview is that you can overlay you HTML mockup onto of the actual composition, to see how "pixel perfect" it is, and you can test different browsers (IE 6, 7, 8, Safari, FireFox, e.g.) opposite each, and even without some of them being installed (by leveraging a service on the Net).

Check it out by downloading the trial here.

Heart Your Silverlight 3

Lars Hundebøl — Wed, 18 Mar 2009 19:33:00 GMT

Maybe it's the brainwashing drugs they give you here at MIX, or maybe it's just because Microsoft have really listen to the developers, but I'm in love with Microsoft.

The new enhancements made to Silverlight 3 (just released in Beta), can now fully compete with Adobes Air/Flex. Here's the short list of cool new features:

GPU accelaration support in both Windows and Mac
H.264 support
Outside Browser support in both Windows and Mac
Perspective 3D support
Bitmap+Pixel API
Support for Pixel Shaders
Improved Deep Zoom
Deep Linking
Improved Text Quality
Multi Touch
100+ Controls (as part of the SDK)
Library Caching Support
