Determines the drive for which the list box displays the directory structure.
property Drive: Char;
__property Char Drive;
When the value of Drive changes, the Directory value changes to the current directory on the specified drive.
C++ Examples:
/* 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. */ void __fastcall TForm1::DriveComboBox1Change(TObject *Sender) { DirectoryListBox1->Drive = DriveComboBox1->Drive; FileListBox1->Drive = DriveComboBox1->Drive; FileListBox1->Directory = DirectoryListBox1->Directory; } void __fastcall TForm1::DirectoryListBox1Change(TObject *Sender) { FileListBox1->Directory = DirectoryListBox1->Directory; }
