There is no method to do this from the IDE. My company built a utility (in VB6) to do our automated build process including steps like you mention (updating version numbers, etc).
The essential trick is that you can run VB6.exe from the command line to compile projects. To see a list of all the option just goto the VB6 directory and type
VB6 /?
A list of all the command line options will appear.
This is what we use for our build utility.
VB6 /Make <project name> /out <errorlog filename>
We copy our project to a temporary project files and alter it using check boxes and parameters files. For example we can choose to compile everything as binary compatible or project compatible. The VB6 project files are easy to manipulate as they are just text. There are any number of things you can do if you write your own build utility.
