String functions in visual basic 6

Visual Basic String Manipulation Functions

Do you want to perform string operations? And looking for the string functions in visual basic 6.0, then we have provided the easy coding for every string function. If you are performing the basic string operations in visual basic 6.0 then you need the string manipulation functions. Without this function, you cannot perform the visual basic string functions. Every string function is performing the specific task.

There are many types of visual basic string functions like Len Function, Ltrim Function, Rtrim Function, and strRevers function. About these string manipulation functions, we will see in detail in another article. Currently, we will discuss source code and the program of string functions in visual basic 6.0. Most of the programmers who want to learn the visual basic 6.0 need this function at least once. So, I have given easy solutions for the string manipulation functions.

This program of a string function is based on three type’s functions. This program will learn about how to concatenate two strings, how to do uppercase string, and how to convert that uppercase string into lower case string. If you want to need more information about these string functions then comment to me in the comment box. Otherwise, you can get more information on these string functions on Wikipedia. First, we will see the program of a string function. So without wasting time let’s see the string functions in visual basic 6.0.

Steps for creating the program of string functions in visual basic

1. Open visual basic 6.0.
2. Create a new form draw the controls.
3. Then draw three textboxes and five buttons (you can draw more controls as per your requirements).
4. After that type the code for every button for performing the specific operation (source code is given in the following with a particular name in the comment section).
5. Then execute the program.

Source code for the String function in visual basic 6.0

Private Sub cmdcon_Click()

'concatinate string

txtr.Text = txtf.Text + txtl.Text

End Sub

 

Private Sub cmdlwr_Click()

'lowercase string

txtr = LCase((txtf.Text + txtl.Text))

End Sub

 

Private Sub reversbtn_Click()

'revers string

txtr = StrReverse(txtf.Text + txtl.Text)

End Sub

 

Private Sub upr_Click()

'uppercase string

txtr = UCase(txtf.Text + txtl.Text)

End Sub

Private Sub clearbtn_Click()

txtf.Text = ""

txtl.Text = ""

txtr.Text = ""

End Sub

What are string functions in Visual Basic?

String functions are the normal functions that are used to manipulate the string. For example, we want to join two strings or write the code to convert a lowercase string into uppercase then we can use these visual basic built-in functions. By using these built in functions in visual basic 6.0, we can perform many types of operations. When you create the projects or any desktop application at that time these functions are very useful for you.

The built in string functions are save most of the lengthy coding of the programmer. Due to these reasons a lot of the programmers like built in functions. Here we also see reverse string function, by using built in reverse string function we can only reverse string, if you want to reverse the number then I have already provided another program you can check here How to display the reverse number in vb 6.0.

How to work this program of sting operations in visual basic 6

After creating the program then executes that program. When you execute the program without any type of error then one form will be displayed. Which are you designed. After that, you want to enter two strings into the two textboxes respectively. Then click on the particular buttons for performing the various operations. When you click a lowercase button then the string will convert into the lowercase and when you click on the uppercase button then the string will be converted into the uppercase.

After the executing program, you can bitterly understand the string functions in visual basic 6.0. Here I have used a few functions, you can try more functions with the same method. I know you understand properly visual basic string manipulation functions. Now we will see the details of every function which we have used in our program.

How to concatenate strings in visual basic 6.0

For concatenating the string you can use the concatenate or plus operator. This operator is also used for performing mathematical operations. Otherwise, you can use another operator that is the “ & ” operator, & the operator also used for the concatenation and perform the logical operations. Both operators can concatenate the string. For example, you want to concatenate the two string, suppose that strings are: (visual) (basic) then the coding will be

Private Sub cmdcon_Click()

display.Text = txtfirststrig.Text + txtlatstring.Text

End Sub

Here the txtfirststring and txtlaststring are the value of the two textboxes that accept strings from the users. I hope now you understood how to concatenate strings in visual basic 6.0. if you have any queries then send your query to us.

How to convert lowercase string to uppercase in visual basic 6.0

For converting the uppercase string into the lowercase then you do not write any type coding. You have simply use the UCase() function. This is the built in function that will automatically convert the lowercase string into the uppercase. For example, you can see the above coding. For displaying the result of this function you want to enter some character of the string in the lowercase format.

How to convert uppercase string to lowercase in visual basic 6.0

Same as UCase() function, converting the lowercase into the uppercase, we want to use a function for converting the string lowercase to uppercase. That functions are LCase(). By using these functions we can convert the lowercase string into the uppercase. When you use this built-in function then you can avoid most of the coding.

Reverse string function in visual basic 6

 This string function is reversing your entered string. Suppose you enter the string “visualbasic” then the output will be display as “cisablausiv”. For reversing the string using the string function. The string function is strReverse. Remember that this function is only reversing the string, not numbers. So, if you entered the numbers sometimes this function will not work. But sometimes it will be work because we are entered the numbers as the string. We have not applied the validation for textboxes.

Why you need visual basic string manipulation functions

If you have read the article properly, you will have noticed that why string manipulation functions are important for us. Normally we can use the string functions in visual basic 6.0 for manipulating the string operations. This program is helpful for the visual basic 6.0 projects. When you create the project in visual basic at that time in the project you used the many types of a form like a login form, registration form, etc.

There you can use these visual basic string functions for validation purposes. You can see our another article How to create traffic signal in visual basic 6.0, which will provide the reference for your projects. I hope you enjoy this article and understood the concept of string functions in visual basic 6.0. if you have any query regarding the string function then comment to me in the comment box.
