The _OPENFILEDIALOG$ function displays a standard dialog box that prompts the user to open a file. The returned string is an empty string ("") if the user cancelled. The returned string will contain file paths delimited using "|" if allowMultipleSelects& is passed as -1 (true) and multiple files are selected by the user.


Syntax

result$ = _OPENFILEDIALOG$([title$][, defaultPathAndFile$][, filterPatterns$][, singleFilterDescription$][, allowMultipleSelects&])


Parameters

  • title$ is the dialog box title
  • defaultPathAndFile$ is the default path that will be used by the dialog box if not changed by the user
  • filterPatterns$ are the file filters separated using "|" (e.g., "*.png|*.jpg|*.gif")
  • singleFilterDescription$ is the single filter description (e.g., "Image files")
  • allowMultipleSelects& can be 0 (false) or -1 (true) if multiple file selection is to be allowed. If omitted, then this defaults to 0 (false)


Description

  • All parameters accept an empty string ("") in which case system defaults are used
  • If singleFilterDescription$ is an empty string (""), then filterPatterns$ will be shown in it's place
  • The dialog box automatically becomes a modal window if the application window is visible


Availability

  • QB64-PE v3.4.0 and up


Examples

Example
Simple open file dialog example
audiofiles$ = _OPENFILEDIALOG$("Open File", "", "*.mp3|*.ogg|*.wav|*.flac", "Audio files", -1)
IF audiofiles$ <> "" THEN _MESSAGEBOX "Information", "You selected " + audiofiles$
