GetOpenFileName method
Syntax FileName = object.GetOpenFileName([FileFilter] [, FilterIndex], [,Title], [,ButtonText])
Opens a standard Windows dialog box for opening a file and gets the name of an existing file from the user (without actually opening any files).
FileFilter Argument type: String
Optional
Specifies one or more file filtering criteria. These are used to fill a List files of type list box in the dialog box, and allow the user to select from different types of files to open.
A file filtering criterion has two parts, separated by a comma: A description, such as "Text Files (*.txt)" or "Settings Files (*.rsf)", and a DOS wildcard file filter specification corresponding to that type of file, such as "*.txt" or "*.rsf". You can specify a single file filtering criterion as shown in these two examples:
"Text Files (*.txt),*.txt"
"All Files (*.*),*.*"
Or multiple file filtering criteria, also separated by commas:
"Text Files (*.txt),*.txt,Bitmaps (*.bmo),*.bmp"
If this argument is omitted, all files are listed.
FilterIndex Argument type: String
Optional
Identifies the default FileFilterthat is, what type of files are listed in the File Type list box when the dialog box first opens. Use 1 to specify the first FileFilter, 2 to specify the second FileFilter, and so on. If you omit this argument, the dialog box will default to the first FileFilter.
Title Argument type: String
Optional
Specifies a title for the dialog box. If this argument is omitted, the title is "Open".
ButtonText Argument type: String
Optional
Specifies the text for the default button in the dialog box. If this argument is omitted, the button text is "Open".
FileName Return type: String
The file name (including drive and path information) the user selects, or an empty string if the user selects Cancel.
