Working with
lengths of strings can come in handy very often. If you need to find how long a string is you can, or if you need to break a string down into parts, you can.
1. Open a new project
2. Add one textbox and Four buttons (excessive but I am breaking each thing down)
3. Name buttons (text AND name)
button1 = btnCountChars
button2 = btnFirstThree
button3 = btnSecondThree
button4 = btnLastThree
4. Double click your first button and add this
[code]
Dim strLengthDemo As String = TextBox1.Text
MessageBox.Show(strlengthdemo.Length.ToString & " characters")[/code]
-This code will show the length of strLengthDemo. You add the ToString part because integers could be added to the textbox.
5. Double click your second button and add this
[code]
Dim strLengthDemo As String = TextBox1.Text
MessageBox.Show(strLengthDemo.Substring(0, 3))[/code]
-This is giving visual basic a starting point and how many characters to grab.
-This will get the first three characters in your textbox
6. Double click your third button and add this
[code]
Dim strLengthDemo As String = TextBox1.Text
MessageBox.Show(strLengthDemo.Substring(3, 3))[/code]
-This will start after the third character and grab 3 more and display them within a messagebox
7. Double click your fourth button and add this
[code]
Dim strLengthDemo As String = TextBox1.Text
MessageBox.Show(strLengthDemo.Substring(strLengthDemo.Length—3))[/code]
-This tells visual basic to get the last three characters of your string.
8. Run your program (F5) and type in a 9 letter word. Or just 9 letters. Click each button to see how it works!
I will keep thinking of more
beginner tuts soon enough. So keep waiting for them if you think I am helping.
