Specifies the names of virtual channel client DLLs to be loaded. Virtual channel client DLLs are also referred to as Plug-in DLLs.

This property is write-only.

Syntax

HRESULT put_PluginDlls(
  [in] BSTR PluginDlls
);

Property value

Comma-separated list of the names of the virtual channel client DLLs to be loaded. The DLL names must contain only alphanumeric characters. For more information about the format of these names, see DVC plug-in registration.

Error codes

Return S_OK if successful.

Remarks

For security reasons, if the control is hosted in a webpage the PluginDlls property only accepts a named list of virtual channel client DLLs. The control returns an error if a file system or UNC path is specified.

Virtual channel client DLLs that will be accessed from a webpage must be installed in the "%WinDir%\system32" directory because the Remote Desktop ActiveX control only accesses DLL files in that location. If the control is not hosted in a webpage, this security restriction does not exist and full paths may be used to access and load virtual channel client DLLs located anywhere on the file system.
