|
// DESCRIPTION
|
|
//
|
|
// This example program creates an archive and adds files to it, while
|
|
// using an ALBarGraph monitor. By default it uses INPUT*.DAT and
|
|
// *.BAK as its input files, but you can modify this by entering new
|
|
// data in the AL_INPUT_FILES text box.
|
|
//
|
|
// This program uses a dialog as its main window. Unlike most of the
|
|
// other Windows examples, this guy doesn't have a dummy frame window
|
|
// around the dialog.
