Introduction

This API requires the version 9.1.15 or newer. When installing the software, the Eng.Wrapper.dll will be installed inside of the binaries folder (xx-9.1). This is the file containing the EngWrapper API.

You must use a WebServer (TWebServer or IIS) configured to the software. When you create a new object for the Project class from the EngWrapper, it will use the WebServer to connect to the project. It is recommended to close the project before using the EngWrapper API or to open the project as a remote development. If you do not do this, you will see the new project configurations when you close and reopen the project.

Every method that adds configuration to a project adds an event to a queue. This event queue will be treated when the Commit method is called. The only methods that do not do this are the runtime methods and the methods that are related to the displays that start with the IntializeCreateDisplays and end with the FinalizeCreateDisplays methods.

There is a Microsoft Visual Studio solution with an example using this API available. Contact support for more information.
