IWMSCacheItemDescriptor.GetContentSize (Visual Basic .NET)

The GetContentSize method retrieves the size of the content, in bytes.

Syntax

Parameters

plContentSizeLow

[out] Reference to an Integer containing the low-order 8 bytes of the content size.

plContentSizeHigh

[out] Reference to an Integer containing the high-order 8 bytes of the content size.

Return Values

This method does not return a value. To report an error, the plug-in can throw a COMException object to the server. If the plug-in uses the IWMSEventLog object to log error information, it is recommended that it throw NS_E_PLUGIN_ERROR_REPORTED (0xC00D157D). Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog object to send custom error information to the Windows Event Viewer, throwing NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about plug-in error information, see Identifying Plug-in Errors.

Remarks

The parameters are 32-bit signed long integers that represent the upper and lower 8 bytes of a 64-bit integer.

Example Code

Imports Microsoft.WindowsMediaServices.Interop
Imports System.Runtime.InteropServices

      SizeLow = ' Determine the low-order bytes of the content size.
      SizeHigh = ' Determine the high-order bytes of the content size.

    Catch Exc As COMException
      Throw New COMException()
    End Try

End Sub
