 | |
|  * 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.
 | |
|  *
 | |
|  *  This program is functionally equivalent to EX00WIN.CPP.  The C version
 | |
|  *  uses the translation layer functions to get the job done, but if
 | |
|  *  you put them side by side, you won't see too much difference.
 | |
|  *
 | |
|  * REVISION HISTORY
 | |
|  *
 | |
|  *  June 12, 1994  1.0A  : First release
 | |
|  *
 | |
|  *  July 11, 1994  1.0B  : Using AL_EXPORT instead of _export.  This lets
 | |
|  *                         the example compile and work properly under NT.
 | |
|  *
 | |
|  *  January 12, 1995 1.01A : Had to #ifdef out the GetInstanceData()
 | |
|  *                           call under Win32.
 | |
|  *
 | |
|  *  January 12, 1995 1.01A : Munged with the Ctl3d stuff.  Some of my 32
 | |
|  *                           bit compilers don't support it, so I need to
 | |
|  *                           put a hack in here to quietly turn it on
 | |
|  *                           and off.
