Hi Welcome to Daniweb Friend :)

Hi...Welcome to Daniweb Friend :)

Introduction
When should you use CType and when should you use DirectCast and which one preforms better? The short answer is: DirectCast is twice as fast for value types (integers...etc), but identical for reference types.

Background
The first thing to understand is that CType and DirectCast are not the same thing. Only CType can convert the underlying object to a new instance of an object of a different type. For example, if you want to turn an integer into a string. Since an Integer doesn't inherit a String, a new instance of a String object must be created in order to store the number as a String. CType can do this, DirectCast cannot. Note: There are other ways to do this too such as the Convert.ToString method or CStr().

Dim MyInt As Integer = 123

Dim MyString1 As String = CType(MyInt, String)

Dim MyString2 As String = DirectCast(MyInt, String) ' This will not work

What DirectCast and CType do have in common is their ability to convert an object to a new type based on inheritance or implementation. For example, if you have a String but it is stored in a variable of type Object, you can use DirectCast or CType to treat that variable as an object of type String because type String inherits type Object. In this case, the underlying data in memory is not actually changing, nor is any processing happening on that data.

Dim MyObject As Object = …

This code running good in desktop application, you can try in web application :

Dim i As Integer
    Dim Con As Control
        
    For i = 0 To Me.Controls.Count - 1
        Con = Me.Controls(i)
        If TypeOf Con Is TextBox Then
            Con.Text = 0
        End If
    Next

Hi
System.String is immutable; System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
StringBuilder is faster when Compared to string
String each time it creates an object.Hence its called Mutable that is changable
Stringbuilder just appends instead of creating new object
String builder class can provide the formatted string facility alway's u have the posibility for appending it can store large data comparatively String class

actually its happened in this morning, but now all things in daniweb was fine. I don't know why this happened.

why you don't make user to do not input string/char inputs? make them to input numbers only. so you don't have to convert input from text to number.

oh, great.
Don't forget to mark this thread solved.
Happy coding friend :)

C# code above become in this following code :

Private Sub button1_ON_Click(ByVal sender As Object, ByVal e As EventArgs)

End Sub

make a new form and put your welcome text on label. use timer to set how long the Welcome Screen shown and use progress bar.

Just a little wrong :

For Each Item As Object In ListView1.CheckedItems
        lstResults.Items.Add(Item.Text)
Next

so, your checkbox on listview is true...
