INPUTBOX$

The _INPUTBOX$ function 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

result$ = _INPUTBOX$([title$][, message$][, defaultInput$])

Parameters

• title$ is an optional dialog box title.
• message$ is an optional message or prompt that will be displayed in the dialog box.
• defaultInput$ is an optional string that is displayed in the text box as the default response if no other input is provided.

Description

• Use message$ to specify instructions to the user.
• All parameters are optional, hence omitting defaultInput$ will display a empty text box
  • However, if defaultInput$ is provided, but is an empty string (""), then a password box is shown, and the text input will be masked.
• The dialog box automatically becomes a modal window if the application window is visible.
• The result$ may be an empty string ("") if the user simply cancelled the dialog.

Availability

• QB64-PE v3.4.0 and up
