Evaluation Limitations

The evaluation version provides all the features except the following:

DateTime Limitation

The date year will be converted to 2000 in the projects that will be written through Aspose.Tasks for C++ as explained in the following code example. This example tries to create a project with two tasks through Aspose.Tasks for C++ without using a license file.

The project file created from the code looks like the one below in Microsoft Project. Note that the Start and Finish dates for Task1 have been converted from 06-Apr-2010 to 06-Apr-2000. Similarly, the Start and Finish dates for Task2 have been converted from 10-Apr-2010 to 10-Apr-2000. These dates are written with the same original year if the project is created using a licensed version of Aspose.Tasks for C++.

MPP Write Support

Aspose.Tasks for C++ supports reading MPP files, updating the project summary information and then writing updated project files in original MPP format. That is if original MPP format belongs to Microsoft Project 2003 version, the MPP file updated through Aspose.Tasks for C++ API will also be in Microsoft Project 2003 MPP format. The same is valid for Microsoft Project 2007, 2010 and 2013 MPP formats. However, this support is only available in licensed versions of Aspose.Tasks for C++.

Applying the License

Once you are happy with your evaluation of Aspose.Tasks for C++, buy a license at the Aspose website. Make yourself familiar with the different licenses offered. If you have any questions, contact the Aspose sales team and they’ll be happy to help you.

Every Aspose license carries a one-year subscription for free upgrades to any new versions or fixes that come out during this time. Technical support is free and unlimited and provided both to licensed and evaluation users.

The license is a plain-text XML file that contains details such as the product name, number of licensed developers, subscription expiry date and so on. The file is digitally signed, so do not modify the file: even adding an extra line break to the file invalidates it.

When to Apply a License

Follow these simple rules:

Applying a License

Use the License.SetLicense method to licensing the component. The easiest way to set a license is to put the license file in the same folder as the Aspose.Tasks.dll and specify the file name, without a path, as shown below.

Applying a License Using File or Stream

This code snippet initializes a license stored in a file or in an embedded resource.

1System::SharedPtr<Aspose::Tasks::License> license = System::MakeObject<Aspose::Tasks::License>();

This code snippet initializes a license from a stream.

1System::SharedPtr<Aspose::Tasks::License> license = System::MakeObject<Aspose::Tasks::License>();
2System::SharedPtr<System::IO::FileStream> myStream = System::MakeObject<System::IO::FileStream>(u"Aspose.Tasks.lic", System::IO::FileMode::Open);

Applying Licensing Using an Embedded Resource

Another neat way of packaging the license with your application and making sure it will not be lost, is to include it as an embedded resource into one of the assemblies that call the component’s DLL (included in Aspose.Email). To include the license file as an embedded resource, perform the following steps:

  1. In Visual Studio .NET, including the license (.lic) file into the project using the Add Existing Item on the File menu.
  2. Select the file in the Solution Explorer.
  3. Set Build Action to Embedded Resource in the Properties window.

To access the license embedded in the assembly (as an embedded resource), you don’t have to call the Microsoft .NET Framework’s System.Reflection.Assembly class’ GetExecutingAssembly and GetManifestResourceStream methods. Instead, just add the license file as an embedded resource to your project and pass the name of the license file to the License class’ SetLicense method. The License class will automatically find the license file in the embedded resources.
