The EngWrapper API facilitates the automation of engineering solutions, allowing developers to generate outputs directly from .NET programming environments. It supports data ingestion from CSV, XML, and JSON formats, streamlining the integration and processing of varied data sets within engineering applications. This API serves as a bridge between raw data inputs and customized engineering outputs.

Requirements

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.

Using the EngWrapper API

The EngWrapper API allows C# or VB.Net NET applications to create and edit projects using third party applications.

When the software is installed, it will install the Eng.Wrapper.dll inside the binaries folder (xx-2016.2). This is the file containing the EngWrapper API.

For this feature, you will need to have a C# or VB.Net NET IDE installed on your computer. We recommend Visual Studio, as there is a sample solution already developed for it.

Through this IDE, you will be able to call one method to create items in the project, without the need to manipulate the project database.

You must use a WebServer (TWebServer or IIS) configured to the software. When creating a new object for the Project class from 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 remote development. If you do not do this, you will see the created project configuration when you close and reopen the project.

There are more details on every available method for the EngWrapper API on the documentation that comes with the sample project. Contact support if you do not have the project files.

To initiate the project configuration, you need to connect to a project using the syntax below:

Code Block

public Project(
string projectFileName, string  version  =  "xx-8.1",
string server = "http://localhost/TProjectServer/", bool enableLogger = false,
bool assetLevel = true)
// Parameters:
// projectFileName: Full filename of the of project file
// version = Product version
//  server  =  TProjectServer  path.  Defaults:  http://IPAddress:Port/TProjectServer/
// enableLogger = Flag indicating whether log is enabled
// assetLevel = Indicates if the assetLevel is created

For more syntax on the other project objects (Tags, Templates, Devices, etc.), see the EngWrapper documentation.

Examples

This section contains examples on API usage in the C# programming language.

Connect to Project:

Code Block
Project project = new Project(@"C:\Projects\Project.tproj","xx-8.1","http://localhost/TProjectServer/",true)

"return a + 1;" + Environment.NewLine +
"}" + Environment.NewLine;
project.AddScriptClass("class1",Project.eScriptCode.CSharp,Project.eDomain.Server,script);

Add Device Node:
