- hostViewOfAddIn
- Type
The type that defines the host's view of the add-in.
- location
- PipelineStoreLocation
The host application's base directory.
Returns
A collection of tokens that represent the add-ins that were found.
- Attributes
Exceptions
There is an access violation to the pipeline directory structure.
location is an invalid PipelineStoreLocation value.
Examples
The following example finds add-ins at the location specified by the PipelineStoreLocation enumeration.
// Search for add-ins of type Calculator (the host view of the add-in)
// specifying the host's application base, instead of a path,
// for the FindAddIns method.
Collection<AddInToken> tokens =
AddInStore.FindAddIns(typeof(Calculator), PipelineStoreLocation.ApplicationBase);
' Search for add-ins of type Calculator (the host view of the add-in)
' specifying the host's application base, instead of a path,
' for the FindAddIns method.
Dim tokens As Collection(Of AddInToken) = _
AddInStore.FindAddIns(GetType(Calculator), PipelineStoreLocation.ApplicationBase)
Remarks
The PipelineStoreLocation enumeration currently contains only the ApplicationBase value, which points to the host's application base directory.

- hostViewOfAddIn
- Type
The type that defines the host's view of the add-in.
- location
- PipelineStoreLocation
One of the enumeration values.
Currently the only value in this enumeration is the directory specified by the ApplicationBase property that was used to set up the host's application domain.
- addInFolderPaths
- String[]
(Optional). The path of the directory that contains one or more subdirectories of add-ins. Because this parameter takes an array of strings, you can specify more than one path.
This parameter is not required if your add-ins are located in the pipeline directory structure under the AddIns folder.
Returns
A collection of tokens that represent the add-ins that were found.
- Attributes
Exceptions
There is an access violation to the pipeline directory structure.
location is an invalid PipelineStoreLocation value.
Remarks
Use this method overload to enable a partially trusted host, which may not have path discovery permission to discover its own location, to find add-ins in its own directory.

- hostViewOfAddIn
- Type
The type that defines the host's view of the add-in.
- pipelineRootFolderPath
- String
The path of the root of the pipeline directory structure.
- addInFolderPaths
- String[]
(Optional). The path of the directory that contains one or more subdirectories of add-ins. Because this parameter takes an array of strings, you can specify more than one path.
This parameter is not required if your add-ins are located in the pipeline directory structure under the AddIns folder.
Returns
A collection of tokens that represent the add-ins that were found.
- Attributes
Exceptions
There is an access violation to the pipeline directory structure.
Remarks
This method examines the store files of cached add-in and pipeline segment information to find all add-ins that match a specified hostAddInView type. You can then use one of the tokens in the returned AddInToken collection to activate a specific add-in by calling the Activate method of the AddInToken class.
