In VBA, you can compare two strings using the ** StrComp** function. In this tutorial, you will learn how to use this function with different comparison methods.

## Using the StrComp Function to Compare Two Strings

The *StrComp* function takes two strings and comparison method as arguments. There are 3 methods of comparison:

*vbBinaryCompare*– compares two strings binary (case-sensitive);*vbTextCompare*– compares two strings as texts (case-insensitive);*vbDatabaseCompare*– this method is available only in Microsoft Access and not in VBA.

By default, the function uses the binary method. If we omit this argument, the function will be case-sensitive.

The function returns the following results:

- 0 – if strings are equal;
- -1 – if string 1 is less than string 2;
- 1 – if string 1 is greater than string 2;
- Null – if one of the strings is empty.

Here is the example code:

Dim intResult As Integer intResult = StrComp("Computer", "Computer")

In this example, we want to check if strings *“Computer”* and *“Computer”* are equal, using the default comparison method (binary). The result of the function is in the *intResult* variable. As you can see in Image, both strings are equal, therefore the *intResult* has value 0.

## Using the StrComp Function with Binary and Textual Method

You will now see the difference between using the binary and textual method. The binary method has a binary number for each character, so the uppercase and lowercase are different characters in this method. On the other side, the textual method considers “S” and “s” as the same letters. If you want to make the function case-insensitive, you need to set the third argument to *vbBinaryCompare*. Here is the code:

Dim intResult1 As Integer Dim intResult2 As Integer intResult1 = StrComp("Computer", "CompuTer") intResult2 = StrComp("Computer", "CompuTer", vbTextCompare)

We want to compare strings *“Computer”* and *“CompuTer”,* using both methods.

In the variable *intResult1*, we will get the value with the binary method, while the *intResult2* will get the value with the textual method. You can see the values of these two variables:

*Image 2. Using the StrComp function with binary and textual method*

The value of *intResult1* is 1, which means that two strings are different for the binary method. For the textual method, these two strings are equal, so the value of *intResult2* is 0.
