TFileListBox.Drive Property

Specifies the drive which contains the files listed in the list box.

Pascal

property Drive: char;

C++

__property char Drive;

Description

Set the value of Drive to the drive that contains the files that the list box should display. When the value of Drive changes, the Directory value also changes to the current directory on the specified drive.

If the form includes a TDirectoryListBox object, set the FileList property of the directory list box to have the Drive property updated automatically when the Drive property of the directory list box changes.

C++ Examples:

Copy Code

/*
The following example assumes that a drive combo box, a file
list box, and a directory list box are on a form. Add this
code as the OnChange event handler for the drive combo box
and the OnChange event handler for the directory list box.
When the user changes the drive using the combo box, the
directory list box and file list box will update to reflect
the new drive and the current directory on that drive.  When
the user double clicks on a directory in the file list box
will update to reflect the new directory.
