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 true(-1) 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 false(0) or true(-1) if multiple file selection is to be allowed. If omitted, then this defaults to false(0)
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
