pszFilename
Type: System.String
[in] Name of file dropped.

pHierSource

[in] Source hierarchy containing the dropped file. This value may be nulla null reference (Nothing in Visual Basic) if the file is not associated with a hierarchy.

pfFileProcessed
Type: System.Int32%
[out, retval] If true, then the file was successfully processed. If false, then the file was not processed.

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsToolboxDataProvider::FileDropped(
   [in]LPCOLESTR pszFileName,
   [in]IVsHierarchy *pHierSource,
   [out,retval]BOOL *pfFileProcessed
);

When your data provider receives notification of a file being dropped on the Toolbox, you can then process the file and add items to the Toolbox. If you successfully process the file, then return a value of true for the pfFileProcessed parameter, or false if you do not process the file.
