Microsoft using a cracked version of Sound Forge 4.5?

2007-06-22T11:28:04Z

So it seems...

Do the following:
Click "My Computer"
Double click the C:/ Drive (Local Disk)
Double click the "WINDOWS" folder
Double click the "Help" folder
Double click the "Tours" folder
Double click the "WindowsMediaPlayer" folder
Double click the "Audio" folder
You will then be presented with WAV files. Right click any one of these, and open it with NotePad. Scroll right to the bottom and you should see this:
"2000-04-06 IENG Deepz0ne ISFT Sound Forge 4.5" The first 4 digits may alter, but everything else stays the same.

Deepz0ne is a very well known cracker.

Are You Ready for 2008? C# 2.0 to C# 3.0 course

2007-06-18T08:04:00Z

Following my previous post, I want to talk more about the course I am going to teach: C# 2.0 to C# 3.0

Course Description:

C# 3.0 introduces several language extensions that build on C# 2.0 to support the creation and use of higher order, functional style class libraries. The extensions enable construction of compositional APIs that have equal expressive power of query languages in domains such as relational databases and XML.

I will go through the 'new'(old...) futures in C# 2.0 (generics, anonymous methods,iterators,...) and while implementing (some of) the fundamentals of LINQ using C# 2.0 futures, you will begin to understand the enormous language change - C# 3.0. Then we will go over the C# 3.0 features and see how easier it is compare to what we did in C# 2.0.

I am preparing a lot of code samples, One is showing C# 3.0 being used to query a process memory for values (wanne hack Solitaire and increase your points?).

The complete syllabus is as follow:

Module 1: C# 2.0 Language Enhancements

Generics
Nullable Types
Anonymous methods
Iterators
BCL Enhancements

Module 2: C# 3.0 Language Enhancements

Implicitly typed local variables
Extension methods
Lambda expressions
Object and collection initializers
Anonymous types
Implicitly typed arrays
Query expressions
Expression trees

Module 3: .NET Language Integrated Query (LINQ)

Getting Started with Standard Query Operators
Language features supporting the LINQ Project
More Standard Query Operators
Query syntax
SQL Integration
XML Integration

Module 4: LINQ to SQL, XML and Object

Queries In Depth
The Entity Life Cycle
Programming XML with XLinq
Mixing XML and other data models

Abracadabra origin.

2007-06-17T17:19:00Z

Have you even wondered what is the origin for this word? I am sure this is going to be quite a shock for some of my Israeli readers.

The origin is from Hebrew/Aramic - Avrei Kadaber, 'I Will create as I speak'.

Have you ever had this moment when you wanted to simply copy and paste something from one computer to another?

Enter a URL that starts with http://cl1p.net.

example: http://cl1p.net/warlike/

Paste in anything you want.

Some text or even a small file. Click 'Save' when done.

On the other computer open a browser to the same URL.

You will find the information you entered in step 2.

No signup, no login. Just enter any URL that starts with cl1p.net. That's it!

CopySourceAsHtml now for Orcas beta 1

2007-06-16T11:03:00Z

If you are not familiar CopySourceAsHtml AddIn for Visual Studio you can read about it here (This is the addin I use to post code in my blog).

Since this addin does not work with Visual Studio Orcas and currently Orcas is my main development enviorment.

I downloaded the source code and compiled it for Visual Studio Orcas beta 1. Visual Studio Orcas just imported the project and it was fine.

You can get the installer and the source

Control.Invoke in C# 3.0 - part 2

2007-06-16T08:27:22Z

After part 1 we can now make the code even more readable by creating Extension Method to System.Windows.Forms.Control

public static class ControlExtentions
{
    public delegate void InvokeHandler();
 
    public static bool SafeInvoke(this Control control, InvokeHandler handler)
    {
        if (control.InvokeRequired)
        {
            control.Invoke(handler);
            return false;
        }
 
        return true;
    }
}

Using it now will look like this:

public void UpdateStatus(string status)
{
    if (transfer.SafeInvoke(() => UpdateStatus(status)))
    {
        transfer.lblStatus.Text = status;
    }
}

The result code has some code that is redundant (the if statement). A small fix and we have this code :

public void UpdateStatus(string status)
{
    transfer.SafeInvoke(() =>
                             {
                                 transfer.lblStatus.Text = status;
                             });
}

Control.Invoke in C# 2.0 and C# 3.0

2007-06-15T20:36:47Z

In C# 2.0 using anonymous methods this code will be:

private delegate void InvokeHandler();
 
public void UpdateStatus(int currentFile, string status)
{
    if (transfer.InvokeRequired)
    {
        transfer.Invoke(new InvokeHandler( delegate() {
            UpdateStatus(currentFile,status);
        }));
        return;
    }
 
    // Do your stuff safe.
}

I really hates the way it looks with anonymous method. In C# 3.0 this code looks much better:

private delegate void InvokeHandler();
 
public void UpdateStatus(int currentFile, string status)
{
    if (transfer.InvokeRequired)
    {
        transfer.Invoke(new InvokeHandler(() => UpdateStatus(currentFile,status)));
        return;
    }
 
    // Do your stuff safe.
}

The only draw is that you have to declare a typed delegate (InvokeHandler) for it because you cannot really create a System.Delegate or System.MulticastDelegate instances.

Thoughts about binding dynamic user controls using LINQ

2007-06-06T17:26:12Z

I am working on a small application which allow the user to create object prefix and suffix. I thought of creating the user controls dynamically and after a few minutes I wrote this cool code sample (not very optimized) that bind a combo box to a dynamic user controls.

Addins.NameAdditionAttribute[] attributes = null;
var list= (from type in System.Reflection.Assembly.GetExecutingAssembly().GetTypes()
            where (attributes = (Addins.NameAdditionAttribute[])type.GetCustomAttributes(typeof(Addins.PrefixAttribute), false)).Length > 0
            select new { Instance = (Addins.ITextAddition)Activator.CreateInstance(type), Name = attributes[0].Name }).ToArray();
 
cmbPrefix.DataSource = list;
cmbPrefix.DisplayMember = "Name";
cmbPrefix.ValueMember = "Instance";

PHEW!

While visiting the Botanic Garden (in National Mall near the Capitol) I got intreduced to the Devil's tongue. This beautiful planet has the worst, disgusting, repulsive, horrible smell you can imagine.

Note: Be careful smelling good looking plants.

The sign says: Pardon my "aroma". I am pollinated by insects that love stinky scents.
