Parameters

cchPropertyName
Type: System.UInt32
[in] Length of szPropertyName.

szPropertyName
Type: array<System.UInt16[]
[out] String containing the property name.

pcchPropertyNameActual
Type: System.UInt32%
[out] Length of property name.

pvspspt
Type: array<Microsoft.VisualStudio.Shell.Interop.VSPROPERTYSTREAMPROPERTYTYPE[]
[out] Pointer to a value from the VSPROPERTYSTREAMPROPERTYTYPE enumeration indicating whether this is a simple property or a substream of the property stream.

pvarValue
Type: System.Object%
[out] A VARIANT containing the property value.

pIErrorLog
Type: Microsoft.VisualStudio.OLE.Interop.IErrorLog
[in] The IErrorLog interface to use for reporting errors.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
