Write a loop statements im visual basic.
Answers
loop statements are those in which the same functions is performed many a times..
Answer:
Visual Basic loop structures allow you to run one or more lines of code repetitively. You can repeat the statements in a loop structure until a condition is True , until a condition is False , a specified number of times, or once for each element in a collection.
Explanation:
Do while
counter <=1000
num.Text=counter
counter =counter+1
Loop
* The above example will keep on adding until counter > 1000
The above example can be rewritten as
Do
counter=counter+1
Loop until counter>1000
9.2 Exiting the Loop
Sometime we need exit to exit a loop earlier when a certain condition is fulfilled. The keyword to use is Exit Do. You can examine Example 9.2 for its usage.
Example 9.2
Dim sum, n as Integer
Private Sub Form_Activate()
List1.AddItem "n" & vbTab & "sum"
Do
n=n+1
sum=sum+n-resize
List1.AddItem n & vbTab & sum
If n=100 Then
Exit Do
End If
Loop
End Sub
Explanation
In the above example, we compute the summation of 1+2+3+4+……+100. In the design stage, you need to insert a ListBox into the form for displaying the output, named List1. The program uses the AddItem method to populate the ListBox. The statement List1.AddItem "n" & vbTab & "sum" will display the headings in the ListBox, where it uses the vbTab function to create a space between the headings n and sum.
