  1. Download iTextSharp.dll. To download click here > Download iTextSharp.dll
  2. Create New Windows Form Project in VB.Net.
  3. Go to Solution Explorer Right Click on the Project and click on Add Reference.
  4. Browse to iTestSharp.dll and click Ok.










  1. Add TextBox to the Form and Set its MultiLine Properties to True.
  2. Add a Button to the Form and Set its Text Properties to "Save to PDF".
  3. Add a SaveFileDialog to the Form.
  4. Now Right Click the Form and Click On View Code.
  5. Now Import the Following References 
Imports System.IO
Imports System.Linq
Imports System.Text
Imports System.Collections.Generic
Imports iTextSharp.text

      6.  Now Double Click on the Button and write the following code :

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
            'Create Docu ment class obejct and set its size to letter and give space left, right, Top, Bottom Margin
            Dim doc As New Document(iTextSharp.text.PageSize.LETTER, 10, 10, 42, 35)
            Try
                Dim wri As PdfWriter = PdfWriter.GetInstance(doc, New FileStream(SaveFileDialog1.FileName  & ".pdf", FileMode.Create))
                'Open Document to write
                doc.Open()
                'Write some content
                Dim paragraph As New Paragraph(TextBox1.Text)
                ' Now add the above created text using different class object to our pdf document
                doc.Add(paragraph)
            Catch dex As DocumentException
                'Handle document exception
            Catch ioex As IOException
                'Handle IO exception
            Catch ex As Exception
                'Handle Other Exception
            Finally
                'Close document
                doc.Close()
                MessageBox.Show("Pdf File Created Successfully", Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Information)
            End Try
        End If
    End Sub

That's All

VS 2005 trick for obtaining the public key token and blob of a signed assembly

Posted by Pearlson

The way to get the public key token using the .NET 2.0 provided utilities is to open a Visual Studio 2005 command prompt and typing: sn.exe -T [full path to strong named assembly]
However, there's an even easier way using the external tools dialog in Visual Studio 2005

  1. In Visual Studio 2005, click Tools -> External Tools...
  2. Click Add and enter the following into the different fields as displayed in the following screen shot:  
    •  Title: Get Public Key 
    • Command: C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\sn.exe  
    • Arguments: -Tp "$(TargetPath)" 
    • Uncheck all options, except Use Output window\
Now, you have a new entry listed in the Tools menu titled Get Public Key as shown in the following screenshot:




Assuming you have a project open that has been configured to be signed when built, and you've built it at least one time, selecting the new Get Public Key menu item from the Tools window to get the public key token and blob in the Output window, as shown here:





 Very slick! You can even take this one step further by adding a button to a toolbar by customizing your toolbar and adding a button from the Tools category. you should pick External Command # where # is the index of the external command from the External Tools window (in my screen shots above, this is External Command 3). Then you can change the name of the button to be Get Public Key as shown below:


Very cool!
