Creating the MyData Component Project

The MyData component is an ActiveX DLL that acts as a data source. In this example, we'll use it to provide data through an OLE DB Simple Provider — it could just as easily be used as an ODBC or OLE DB data source. First we'll need to add another project to the AXData project group.

Note   This topic is part of a series that walks you through creating sample data source components. It begins with the topic Creating Data Sources.

To add a test project to the project group

1. On the File menu, click Add Project to open the Add Project dialog box.

   Important   Do not click Open Project or New Project, as these will close your control project.

2. Double-click the ActiveX DLL icon to add a DLL component project. This will add a new project, Project 2, and a new class module, Class1, to the Project Explorer****window.

3. Select Project2 in the Project Explorer, then double-click the Name property in the Properties window and change the Name to MyDataComponent.

4. Choose MyDataComponent Properties from the Project menu to display the Project Properties dialog. Set the properties for the MyDataComponent project as follows:

5. Select References from the Project menu. Add the following references in the References dialog box:

6. Select Save Project Group from the File menu to save your changes before moving on to the next step.

In the next step, we'll create a class that implements the OLE DB Simple Provider interface.
