Adding Files To The Project
we add the zlib files to the project, we need to move some of the files
first. Depending on where your project is located and where you
unzipped the zlib source code, you may need to make some adjustments by
moving essential files into your VC++ project's folder, or at least near
it to make including files easier.
I have the following directory structure for my project.
- VBZip (root folder)
- vbgamerzip (contains the VC++ project files)
- zlib122 (unzipped directory tree of the zlib code, version 1.22)
There are other folders, but these are the important ones.
files you need to move are listed below. The most important move
is to move the needed files from the "minizip" folder to the folder
containing the zlib files. For my project I copied the files from
"minizip" to the "zlib122" folder. Optionally you can copy the
contents of zlib122 and minizip to the vbgamer zipfolder. It's
your choice, but you'll need to know the relative location of the zlib
code (in this case ..zlib122) to the vbgamerzip folder.
Organizing The Files
to VC++. Now that you've moved the essential files (listedbelow),
the next step is to add them to the VC++ project. You don't need
to orangize them as I have, so organize the files however you want.
you don't have the Workspace window open, press Alt+0 (number zero) to
open it. In the File View tab, right click on the "SourceFiles"
folder and then select "New Folder..." from the menu.
used the name "Zlib Source" for this first folder. This
doesn't create a folder on your hard drive, this is simply an
organization tool within VC++.
Next, right click on the folder
you just created and then select "Add Files to Folder..." from the
menu. Find the folder that contains your zlib files and add the
following files to this folder. Note, you won't need all files in
the folder. Make sure you only add the files in these lists.
next folder should be created under the "Header Files" folder.
Name this one "Zlib Header" and add the following files:
19 files make up the code needed to compress raw data using
the "deflate" method of compression. The inverse of "deflate"
is called "inflate," which is used for decompression. The next set of files will be the files
copied from the minizip folder. These files contain the code
needed to create and read zip files.
Under the "Source Files" folder create a new folder called "Minizip Source" and then add the following files.
Next, create a new folder under "Header Files" called "Minizip Header." Add the following files:
We're not finished, but to make sure everything works, so let's do a test compile of our DLL.
the toolbar in VC++ there should be a dropdown combo box that allowsyou
select either Win32 Release or Win32 Debug. Since we don't need a
debug version of this DLL, lets select Win32 Release
from the list.
can then click the Build button on the toolbar or select
"Build vbgamerzip.dll" from the Build menu. If you did
everthing correctly, there should be a file named "vbgamerzip.dll" in
If there were any errors reported, go back over the tutorial to make sure you did everything correctly.
