{
The SHFormatDrive API provides access to the Shell's format
dialog box. This allows applications that want to format disks to bring
up the same dialog box that the Shell uses for disk formatting.

Normally, if a diskette is not in the drive when SHFormatDrive is called,
the system displays a critical error dialog box that asks the user
to Abort, Retry, or Ignore.
You can prevent the system from displaying this dialog box by calling
the SetErrorMode API with SEM_FAILCRITICALERRORS.
}
var
EMode: Word;
begin
EMode := SetErrorMode(SEM_FAILCRITICALERRORS);
// ShFormatDrive Code....
SetErrorMode(EMode);
end;
