Called when a managed VSTO Add-in is loaded.
Syntax
HRESULT Load([in] BSTR bstrManifestURL,
[in] IDispatch *pdispApplication);
Parameters
| Parameter | Description |
|---|---|
| bstrManifestURL | The full path of the manifest for the VSTO Add-in. |
| pdispApplication | A pointer to an IDispatch that represents the host application that is loading the VSTO Add-in. |
Return Value
An HRESULT value that indicates whether the method completed successfully.
Remarks
A manifest is a file (typically, an XML file) that provides information that is used to help load the VSTO Add-in. For example, a manifest can specify the location of the VSTO Add-in assembly and the entry point class to instantiate when the VSTO Add-in is loaded.
The bstrManifestURL parameter contains the value of the Manifest entry under the HKEY_CURRENT_USER\Software\Microsoft\Office\<application name>\Addins\<add-in ID> registry key for the VSTO Add-in. For more information, see IManagedAddin interface.
Implement the IManagedAddIn::Load method to perform tasks such as configuring the application domain and security policy for the VSTO Add-in that is being loaded.
