InputBox Function

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

Displays a prompt in a dialog box, waits for the user to input text or click a button, and returns a String containing the contents of the text box.

Syntax

InputBox(prompt[, title] [, default] [, xpos] [, ypos] [, helpfile, context])

The InputBox function syntax has these named arguments:

Part

Description

prompt

Required. String expression displayed as the message in the dialog box. The maximum length of prompt is approximately 1024 characters, depending on the width of the characters used. If prompt consists of more than one line, you can separate the lines using a carriage return character (Chr(13)), a linefeed character (Chr(10)), or carriage return–linefeed character combination (Chr(13) & Chr(10)) between each line.

title

Optional. String expression displayed in the title bar of the dialog box. If you omit title, the application name is placed in the title bar.

default

Optional. String expression displayed in the text box as the default response if no other input is provided. If you omit default, the text box is displayed empty.

xpos

Optional. Numeric expression that specifies, in twips, the horizontal distance of the left edge of the dialog box from the left edge of the screen. If xpos is omitted, the dialog box is horizontally centered.

ypos

Optional. Numeric expression that specifies, in twips, the vertical distance of the upper edge of the dialog box from the top of the screen. If ypos is omitted, the dialog box is vertically positioned approximately one-third of the way down the screen.

helpfile

Optional. String expression that identifies the Help file to use to provide context-sensitive Help for the dialog box. If helpfile is provided, context must also be provided.

context

Optional. Numeric expression that is the Help context number assigned to the appropriate Help topic by the Help author. If context is provided, helpfile must also be provided.

Remarks

When both helpfile and context are provided, the user can press F1 (Windows) or HELP (Macintosh) to view the Help topic corresponding to the context. Some host applications, for example, Microsoft Excel, also automatically add a Help button to the dialog box. If the user clicks OK or presses ENTER , the InputBox function returns whatever is in the text box. If the user clicks Cancel, the function returns a zero-length string ("").

NoteNote

To specify more than the first named argument, you must use InputBox in an expression. To omit some positional arguments, you must include the corresponding comma delimiter.

This example shows various ways to use the InputBox function to prompt the user to enter a value. If the x and y positions are omitted, the dialog box is automatically centered for the respective axes. The variable MyValue contains the value entered by the user if the user clicks OK or presses the ENTER key . If the user clicks Cancel, a zero-length string is returned.

Dim Message, Title, Default, MyValue
Message = "Enter a value between 1 and 3"    ' Set prompt.
Title = "InputBox Demo"    ' Set title.
Default = "1"    ' Set default.
' Display message, title, and default value.
MyValue = InputBox(Message, Title, Default)

' Use Helpfile and context. The Help button is added automatically.
MyValue = InputBox(Message, Title, , , , "DEMO.HLP", 10)

' Display dialog box at position 100, 100.
MyValue = InputBox(Message, Title, Default, 100, 100)
