System.WeakReference<T>
I’d like to recommend a useful gadget. It can help you figure out the most bulky files / folders on the disk, and it works really fast!

Recently I’ve programmed a tool that can automatically generate albums in PowerPoint. What you’re supposed to do is to prepare your photos, and write a script. When these materials are ready, just run this little application and you’ll get the presentation document.
Here’s a quite simple demo
Okay, I’ve to say I put it here so that I can simply copy & paste & run it when it’s needed.
While Application.Presentations.Count > 0 : Application.Presentations(1).Close : Wend
It pains to write submission summary.
We can use My.Computer.Network.IsAvailable in Visual Basic.NET to determine whether the network is connected. The definition of this property is:
'''**********************************************************************
''';IsAvailable
''' <summary>
''' Indicates whether or not the local machine is connected to an IP network.
''' </summary>
''' <value>True if connected, otherwise False</value>
''' <remarks></remarks>
Public ReadOnly Property IsAvailable() As Boolean
Get
Return NetInfoAlias.NetworkInterface.GetIsNetworkAvailable()
End Get
End Property
It leads to the approach in C#. Continue reading “Querying Network Status in .NET programming”

You can generate IL code, and thereby construct a methods, using ‘System.Linq.Expression’ during runtime.Compared to ‘System.Reflection.Emit.ILGenerator’, use expression trees to construct dynamic methods is an easier way to handle IL code.As you know, IL instructions is just like any kind of assemly, which is rather elaborate. I just cannot handle it well enough 🙁 Continue reading “Some debugging tips on Linq.Expression”
Suddenly Visual Basic 6.0 ……
Yesterday once more.
And
There’s virtually no way to debug into it…
So I had to use something like `Debug.Print`. Really had a hard time.

Try it out today and found that 'WebClient' supports asynchronous, but it really does not support concurrent … …
