ASP.NET nullreference

[Guest]

hi following problem in my asp.net project:

i have embedded folloging ocx object in my aspx html code:
<OBJECT id="VideoCapX1" style="Z-INDEX: 101; LEFT: 216px; WIDTH: 368px;
POSITION: absolute; TOP: 120px; HEIGHT: 288px"
classid="clsid:912FB007-DD9A-11D3-BD8D-DAAFCB8D9378" >


then i want to get the object in my aspx.vb code...

Protected WithEvents VideoCapX1 As VIDEOCAPXLib.VideoCapX
VideoCapX1 = CType(Me.FindControl("VideoCapX1"), VIDEOCAPXLib.VideoCapX)

okay...now i want to change a property of it:
VideoCapX1.Connected = False

and there´s the error message at "VideoCapX1.Connected = False":

"Object reference not set to an instance of an object"
"System.NullReferenceException: Object reference not set to an instance of
an object"

can anyone help me?

My advice is to get away from the embedded object reference and move
completely to code behind. To do this, you will be best served by creating a
..NET wrapper. If you use Visual Studio, adding a COM reference creates the
wrapper for you. If not, use tlbimp.exe to create the wrapper.

I am not fond of declaratively setting up an object that has to be used
programatically. Your mileage may vary.
