Refreshing the tdrivecombobox drive list
<![CDATA[
Question:
How can I get the TDriveComboBox component to refresh its' list,
given that networked drives can be added, deleted, and remapped, and
drives can be hot swapped by using plug and play devices?
Answer:
The following example demonstrates surfacing the protected
BuildList() method of the TDriveComboBox component to regenerate the
list of current disk drives.
Example:
type
TNewDriveComboBox = class(TDriveComboBox)
end;
procedure TForm1.Button1Click(Sender: TObject);
var
Drive : char;
begin
Drive := DriveComboBox1.Drive;
TNewDriveComboBox(DriveComboBox1).BuildList;
DriveComboBox1.Drive := Drive;
end;
