VB 6 – UCase() and LCase()

In Visual Basic 6, there are two important functions to change a string to uppercase or lowercase. In this example, you will build a small application that takes a string and returns uppercase or lowercase version depending on user choice.


Program Code: UCase () and LCase()

First look at the code for first button – UpperCase.

Private Sub Command1_Click()
Text2.Text = UCase(Text1.Text)
End Sub

Now code for button – LowerCase.

Private Sub Command2_Click()
Text2.Text = LCase(Text1.Text)
End Sub

Output – UCase () and LCase()

Output - String Handling - LowerCase and UpperCase
Output – String Handling – Lowercase and Uppercase
