```APIDOC
IGuidCollection Interface Reference

Represents a GUID collection.

Public Member Functions:

HRESULT Get ( [in] int index, [out, retval] GUID *pGUID )
  Returns the GUID by index.

HRESULT GetS ( [in] int index, [out, retval] BSTR *pGUID )

### Renga Local Server C++ Example

Source: https://github.com/jackdainzh/rengabim-sdk/blob/main/Docs/how-to-local-server.html

Demonstrates how to initialize COM, create a Renga application instance as a local server, manage its visibility, open a project, and quit the process using RAII.

```cpp
CoInitialize(nullptr);

auto renga = Renga::CreateApplication(CLSCTX_LOCAL_SERVER);

renga->PutVisible(VARIANT_TRUE);

renga->OpenProject(bstr_t(argv[1]));

... // use Renga someway

renga->CloseProject(VARIANT_TRUE);

// Quit explicitly:

renga->Quit();

CoUninitialize();

The other way is to use RAII:

CoInitialize(nullptr);

{

auto renga = Renga::CreateApplication(CLSCTX_LOCAL_SERVER);

renga->CloseProject(VARIANT_TRUE);

renga->OpenProject(bstr_t(argv[1]));
