SUMMARY

In Microsoft Excel, you can create a Microsoft Visual Basic for Applications procedure that uses an input box to gather data from a user. To create an input box, you can use the InputBox method or the InputBox function. The main difference between the InputBox method and the InputBox function is how you use them to check the entered data to see if it is correct.

InputBox Method

The InputBox method contains a type argument that you can use to specify the type of data to be entered. You can recognize that the InputBox method is being used if "InputBox" is preceded by the Application object. Also, if you click Cancel in the input box, the InputBox method returns False.

InputBox Function

You must use conditionals such as If statements or Case statements to verify the type of data that is entered. The InputBox function can give you more control over the input and allows you to use custom error messages.

You can distinguish the InputBox function from the InputBox method by the Application object; the function is not preceded by the Application object. In addition, the function lacks an argument for checking the type of the entered data. If you click the Cancel button in an input box, the InputBox function returns an empty text string, "".

The following examples display an input box that asks you for a number. When you enter a number and press ENTER or click OK, the number is written to cell A1 in the first worksheet of the active workbook. If you enter text, an error message appears and the box continues to be displayed. If you decide not to enter anything, you can click Cancel and the box is dismissed.

InputBox Method

In the following example, the "1" just before the closing parenthesis indicates that only numbers are accepted by the input box. If you enter anything else, such as text or a formula, the InputBox method displays an error message. The macro uses the If statement to see if Cancel is clicked. If Cancel is not clicked, the macro writes the entered value to cell A1 on the first worksheet.

   Sub Using_InputBox_Method()
      Dim Response As Integer

      ' Run the Input Box.
      Response = Application.InputBox("Enter a number.", _
         "Number Entry", , 250, 75, "", , 1)

      ' Check to see if Cancel was pressed.
      If Response <> False Then

         ' If not, write the number to the first cell in the first sheet.
         Worksheets(1).Range("a1").Value = Response

      End If

   End Sub 

The Input Box Function

In the example below, a series of If statements is used to check the entry. The InputBox is inside a While loop to allow it to be re-shown if an error occurs. If all the conditions are true, the entered number is written to cell A1 on the first worksheet and the loop is ended.

   Sub Using_InputBox_Function()
      Dim Show_Box As Boolean
      Dim Response As Variant

      ' Set the Show_Dialog variable to True.
      Show_Box = True

      ' Begin While loop.
      While Show_Box = True

         ' Show the input box.
         Response = InputBox("Enter a number.", _
            "Number Entry", , 250, 75)

         ' See if Cancel was pressed.
         If Response = "" Then

            ' If Cancel was pressed,
            ' break out of the loop.
            Show_Box = False
         Else
            ' Test Entry to find out if it is numeric.
            If IsNumeric(Response) = True Then
               ' Write the number to the first
               ' cell in the first sheet in the active
               ' workbook.
               Worksheets(1).Range("a1").Value = Response
               Show_Box = False
            Else
               ' If the entry was wrong, show an error message.
               MsgBox "Please Enter Numbers Only"
            End If
         End If
      ' End the While loop.
      Wend
   End Sub 
After you run the macro, the number you entered into the input box is in cell A1 on Sheet1.
