hi i wanted to write an application where i could open my browsers default mail client, i was unable to find any thing in .NET hence this code.. enjoy


I was writing an emailing application in VB.NET when I came across a situation where I needed to load the default email client of the user's machine with all the email fields filled up.  I was not able to find a suitable solution for this on the Internet hence I thought why not write one.  It is easy to understand.  For comments please mail me at


Building The Message

public class OpenDefaultClient
Function openclient()
'string builder used for concatination
Dim MsgBuilder As New System.Text.StringBuilder
MsgBuilder.Append("<A href=""></A>")
MsgBuilder.Append("<A href="mailto:&,">&,</A>")
MsgBuilder.Append("<A href="mailto:&,">&,</A>")
MsgBuilder.Append("&subject=this is test subject")
MsgBuilder.Append("&body=this is test body")
End Function 

Starting The Default Email Client

Private Function ExecuteFile(ByVal FileName As String) As Boolean
Dim myProcess As New Process
myProcess.StartInfo.FileName = FileName
myProcess.StartInfo.UseShellExecute = True
myProcess.StartInfo.RedirectStandardOutput = False
End Function
