How can I print a web page?

Some browsers support Javascript's Window.Print() method. You can use it in the click event of a control, say a button.

<input type="button" value="Print this window" onClick="Window.Print()"/>

This will bring up a Print Dialog which is good thing since it will allow you make up your mind whether you really want to print; allows you to see if Printer is turned on, etc.


Another way would be to place a Web Browser Control on a windows form. Use the WebBrowser's navigate() method to go to the page you want at form load. Then use the click event of a button to Print.

Ofcourse you need to add a PrintDocument control from Toolbox to your form.



Code Follows:

Imports System.Windows.Forms.WebBrowser

Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Me.Load

WebBrowser1.Navigate("http://hodentek.blogspot.com/")
End Sub


Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click

PrintDocument1.Print()

'The above will print the Form1

End Sub

End Class

What can the string function StrDup() do ?

First of all StrDup() fuction is a member of the Microsoft.VisualBasic.Strings.

It comes in three flavors:

StrDup(Integer,Char) as String

StrDup(Integer, Object) as Object

StrDup(Integer,String) as String

What it returns in each case is the first character of the

string the number of times.

Say, if the string is "yes" and the integer is 7 you would get

yyyyyyy as the return value. In the case of the argument

Object, the object should be either a string or a char.

Observe the following listing:

I need to convert a string into a Byte Array. How do I code it in Visual Studio?

Visual Studio has Microsoft Visual Basic already referenced and you can use the following code. Of course you need to add an imports statement as shown. This code was tested using Visual Studio 2008.

In this code I am converting the string "Welcome" to a Byte array and writing it to the immediate window.
