Internal Constants
Many of the fields in the DWebPro configuration file specify a path. Since the drive letter of the CD/DVD on which the Web site will run will not be known, it is obvious that paths referenced by DWebPro will have to be dynamically determined at run time. DWebPro solves this issue by using several internal constants to access and substitute dynamic values. The following table details the DWebPro internal constants.
| Internal Constant | Description |
|---|---|
##TEMP## or ##DWEBPRO_TEMP## ##PROGRAMFILES## or ##DWEBPRO_PROGRAMFILES## ##WINDOWS## or ##DWEBPRO_WINDOWS## ##SYSTEM## or ##DWEBPRO_SYSTEM## |
These internal constants refer to standard Windows folders. |

This constant contains the MD5 value of the dwebpro.exe file. This value is useful in helping
to protect a distributed Web application against piracy. |
