Reverse a String in VB6

[Javilon06]

Hi! In this tutorial, we will create a program that reverses a string. I already made this one in vb.net but it has different code in vb6.0.

Now, let's start this tutorial!

1.Let's start this tutorial by following the following steps in Microsoft Visual Basic 6.0: Open Microsoft Visual Basic 6.0, click Choose Standard EXE, and click Open.

2. Next, add only one Button named Command1 and labeled it as "Reverse". Add one TextBox named Text1 for your input and also one Label named Label1 that will serve to display your output.You must design your interface like this:

3.Now put this code for your code module. This code is for Command1_Click:

1. Private
   
   Sub
   
   Command1_Click()
   
2. 
   
3. Dim
   
   lLen As
   
   Integer
   
   , lCtr As
   
   Integer
   
4. Dim
   
   sChar As
   
   String
   
5. Dim
   
   sAns As
   
   String
   
6. 
   
7. lLen = Len(Text1.Text)
   
8. For
   
   lCtr = lLen To
   
   1 Step
   
   -1
   
9. sChar = Mid(Text1.Text, lCtr, 1)
   
10. sAns = sAns & sChar
    
11. Next
    
12. 
    
13. Label1.Caption = sAns
    
14. 
    
15. End
    
    Sub
    

Explanation:

We initialized lLen as Integer to hold the length of the text inputted in Text1. Len function returns an integer containing either the number of characters in a string or the nominal number of bytes required to store a variable. Then we have created a For Next loop that the lCtr variable will hold the value of variable lLen up to 1 Step -1. Step specifies an increment value for a loop counter. sChar variable was used to get the middle of Text1, the start of the mid which is lCtr and 1 as the length. Mid Function returns a string containing a specified number of characters from a string. Then sAns variable will hold the value of our variable sChar and will be displayed in Label1.
