HOWTO: Windows Powershell and DVBViewer

[dbraner]

Hi all,

 

the windows powershell is installed with Windows 7 by default. For older Windows versions it can be downloaded from Microsoft for free. To start powershell in Windows 7 simply type in "powershell" in the search field of the start menu.

 

Here is a short example how DVBViewer can be controlled by powershell:

 

$MyDVB = new-object -comobject "DVBViewerServer.DVBViewer"
$MyDVB.SendCommand(42)

 

The example above will start DVBViewer and activate channel 2 (actionid = 42). There should be no blank between SendCommand and "(42)". The command fails if DVBViewer is already running.

 

EDIT: Accessing an already running DVBViewer:

 

$MyDVB = [System.Runtime.InteropServices.Marshal]::GetActiveObject("DVBViewerServer.DVBViewer")

 

You can get a listing of all methods and properties of the $MyDVB object with the command:

 

$MyDVB | get-Member

 

For further operations see the DVBViewer COM interface documentation. It should be possible to use events too, have to test this.
