Developing a COM DLL with COM Attributes
Visual Studio .NET 2003
The following topics demonstrate how to quickly develop a simple COM server (an inproc server or DLL) using various attributes. You can develop the COM server in two ways:
- Walkthrough: Creating a COM Server Using a Text Editor
- Walkthrough: Creating a COM Server Using Wizards
The first walkthrough develops the COM server using a text editor and the command-line tools. The second walkthrough develops the same COM server using the Visual Studio integrated development environment.
Note The UUID used in this topic is purely for demonstration purposes only. If omitted, the module attribute (and other attributes) will automatically generate one for you.
This topic focuses on the following attributes:
| coclass | object | threading |
| dual | out | uuid |
| emitidl | pointer_default | version |
| helpstring | progid | vi_progid |
| module | retval |
