Comments

Call DTwainInterface::StartSession function to start a TWAIN session.  If hTwainWnd is NULL, DTWAIN will internally create a window that will capture the TWAIN messages.  If szTwain is an empty string, DTWAIN uses the default name for the TWAIN Source Manager DLL.

Alternately, a Twain session can be started on construction of the DTwainInterface object.
