C++ CATIDs
The following Visual C++ project system CATIDs are not exposed in type libraries in Visual Studio .NET 2003 and have to be included in your code whenever you want to extend these project objects. These CATIDs will be included in the type libraries in later releases of Visual Studio.
| Name | GUID |
|---|---|
CVCProjectNode |
{EE8299CB-19B6-4f20-ABEA-E1FD9A33B683} |
CVCFolderNode |
{EE8299CA-19B6-4f20-ABEA-E1FD9A33B683} |
CVCFileNode |
{EE8299C9-19B6-4f20-ABEA-E1FD9A33B683} |
The following code example demonstrates how to program these CATIDs in your code.
const LPOLESTR CVCProjectNode::s_wszCATID = L"{EE8299CB-19B6-4f20-ABEA-E1FD9A33B683}";
const LPOLESTR CVCFolderNode::s_wszCATID = L"{EE8299CA-19B6-4f20-ABEA-E1FD9A33B683}";
const LPOLESTR CVCFileNode::s_wszCATID = L"{EE8299C9-19B6-4f20-ABEA-E1FD9A33B683}";
The following Visual C++ project system CATIDs are also not exposed in the type libraries in Visual Studio .NET 2003 and have to be included in your code whenever you want to extend these project objects. These CATIDs are available only in Visual Studio .NET 2003 and will not be available in the later releases of Visual Studio.
