Input Box

Have you ever had an Excel worksheet that needed specific input from the user for some calculations? Most applications rely on data inputs from users to determine various functions or procedures. Excel has a number of functions that allow you to gather user input for your applications. This article will show you how to use the Excel VBA InputBox function to get user input for your worksheets.

 

An InputBox is a function that allows the user to enter a value into a dialog box. The result of an InputBox is Stored Normally to a variable and remembered for later use in a procedure.

Note: result of an InputBox is always a String Value

Now suppose you want to change the title of the InputBox function. You can use the InputBox function optional argument to do this. The following code will allow you to change the title of the InputBox function

myValue = InputBox(“Enter a number”,”Hi”,1)

STEP12 The result will be an InputBox having the title Hi. That's it you have now successfully created an InputBox function.
