ScreenRecorder in .NET 3.0

Requirements:

* .NET 3.0 installed on the computer.
* WPF Extensions for VS 2005

(Both found on Microsoft.com)

What you need to do:

1. Create a new "Windows Application (WPF)"

2. Add a reference to System.Drawing.dll, and System.Windows.Forms.dll
3. Add the following code:

Code

Public Class ScreenRecorder

Private Shared tempDir As String = My.Computer.FileSystem.SpecialDirectories.Temp & "\snapshot\"
Private Shared snap As New System.Threading.Thread(AddressOf Snapshot)
Private Shared _Bounds As System.Drawing.Rectangle = System.Windows.Forms.Screen.PrimaryScreen.Bounds
Public Shared Property Bounds() As System.Drawing.Rectangle
Get
Return _Bounds
End Get
Set(ByVal value As System.Drawing.Rectangle)
_Bounds = value
End Set
End Property
Private Shared Sub Snapshot()
If Not My.Computer.FileSystem.DirectoryExists(tempDir) Then _
My.Computer.FileSystem.CreateDirectory(tempDir)
Dim Co As Integer = 0
Do
Co += 1
System.Threading.Thread.Sleep(50)
Dim X As New System.Drawing.Bitmap(_Bounds.Width, _Bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)
Using G = System.Drawing.Graphics.FromImage(X)
G.CopyFromScreen(_Bounds.Location, New System.Drawing.Point(), _Bounds.Size)
Dim CurBounds As New System.Drawing.Rectangle(System.Windows.Forms.Cursor.Position - Bounds.Location, System.Windows.Forms.Cursor.Current.Size)
Forms.Cursors.Default.Draw(G, CurBounds)
End Using
Dim FS As New IO.FileStream(tempDir & FormatString(Co.ToString, 5, "0"c) & ".png", IO.FileMode.OpenOrCreate)
X.Save(FS, System.Drawing.Imaging.ImageFormat.Png)
X.Dispose()
FS.Close()
Loop
End Sub
Public Shared Sub ClearRecording()
If My.Computer.FileSystem.DirectoryExists(tempDir) Then _
My.Computer.FileSystem.DeleteDirectory(tempDir, FileIO.DeleteDirectoryOption.DeleteAllContents)
My.Computer.FileSystem.CreateDirectory(tempDir)
End Sub
Public Shared Sub Save(ByVal Output As String)
Dim G As New Windows.Media.Imaging.GifBitmapEncoder

Dim X As New List(Of IO.FileStream)
For Each Fi As String In My.Computer.FileSystem.GetFiles(tempDir, FileIO.SearchOption.SearchTopLevelOnly, "*.png")
Dim TempStream As New IO.FileStream(Fi, IO.FileMode.Open)
Dim Frame = Imaging.BitmapFrame.Create(TempStream)
X.Add(TempStream)
G.Frames.Add(Frame)
Next
Dim FS As New IO.FileStream(Output, IO.FileMode.OpenOrCreate)
G.Save(FS)
FS.Close()

For Each St As IO.FileStream In X
St.Close()

Next

End Sub
Public Shared Sub Start()
snap = New System.Threading.Thread(AddressOf Snapshot)
snap.Start()
End Sub
Public Shared Sub [Stop]()
snap.Abort()
End Sub
Private Shared Function FormatString(ByVal S As String, ByVal places As Integer, ByVal character As Char) As String
If S.Length >= places Then Return S
For X As Integer = S.Length To places
S = character & S
Next
Return S
End Function

End Class


To use the code:
Starting:
Code

ScreenRecorder.Start


Stopping:
Code

ScreenRecorder.Stop



Saving:
Code


ScreenRecorder.Save("")


Setting the recording boundries:
Code


ScreenRecorder.Bounds = New System.Drawing.Rectangle(300, 300, 500, 300)


Erasing the recording:
Code


ScreenRecorder.ClearRecording()
