Get the latest version (see
Latest Version). To run the Demo select the .SWS file from the Demo workspace that matches your installed versions of VDF and Codejock.
To use the library in your application, in the Studio select Tools | Maintain Libraries and select the .SWS file form the Classes workspace that matches your installed versions of VDF and Codejock.
You will never need to select a Wrapper workspace. The Classes workspace .SWS files have already been linked to the required Wrapper Workspace.
Codejock Evaluation version
The Wrapper workspaces support both the Codejock Full and Evaluation versions. To use the Wrapper with the Evaluation version you will need to edit the file
SigCjLicense_vn.n.n.pkg
located in
…SigCodejock Wrapper nn.n.nAppSrc
where n.n.n is the Codejock version.
Scroll down to the end of the header comments and uncomment the first Define statement.
//Define SigCj_Use_Demo_Codejock_License
This will switch the wrapper from the Full license to the Evaluation license.
Supported Versions
We plan to support all combinations of the current and previous two versions of both VDF and Codejock. For a Codejock version we ignore the last digit, so 12.0.0 / 12.0.1 & 12.0.2 are all considered to be version 12.0. When support is dropped for 12.0, support for all three Codejock versions will be stopped.
VDF 14.1 introduced compatibility issues in the Wrappers and the Data Dictionary classes. The support policy means that when VDF15.1 is released the Demo workspace will be made compatible with VDF14.1. Until then you will see DD compatible warnings in the Studio (VDF14.1 & above) when running the Demo.
The Wrapper workspaces for all Codejock versions release after VDF15.1 is released will only be compatible with VDF14.1 and above.
The project is held in a version control system called Subversion (SVN). If you wish to use Subversion, you need to install a Subversion client on your development PC. We recommend that you install the Tortoise client for SVN. This is available from
After you have installed Tortoise, start Windows Explorer, right click on any folder and select the Tortoise menu item, then select repo-browser to bring up the subversion browser. You will need to enter http://blackbird.asckey.net:81/svn/sigcj/ as the URL.
When it asks for user name and password, enter
Name vdfsig
Password codejock
This will give read only access. If it asks for the name and password again, it’s the same pair.
You can now copy the whole lot to your local disk (the nightly code is in Trunk, the released code is in Tags) by check out or export (don’t use copy, that’s internal to the source). For completeness, "check out" adds hidden material that would allow you to check back in, or use the update docs features of the Subversion system. For "just" accessing the material this is not significant.
An install program is created periodically. This is provided for people who are unable to use SVN. The Demo and Classes workspaces are always changing and the install program will probably be out of date. Click here to download it.
