I use LTMM 17.5 Capture sample(.Net).

When I use LTMM 16, I just use like below.
-----------------------------------------
Dim nIndex As Integer
Dim cropsize As LMVCrop

nIndex = AxltmmCaptureCtrl1.VideoProcessors.Find("UNIQUE CODE")
AxltmmCaptureCtrl1.SelectedVideoProcessors.Add(AxltmmCaptureCtrl1.VideoProcessors.Item(nIndex), 0)

cropsize = AxltmmCaptureCtrl1.GetSubObject(ltmmPlay_Object_SelVideoProcessor)
cropsize.Enabled = True
------------------------------------------------
I tried to do like above, but I cannot.

I think I should use different method.
I want to know, how to use video processor more details.

If you can, please give me some sample code or suggest the section of help. (I already read LEADTOOLS filters Help -> Video filters ..)
(I just want to use video filter using one button, not like sample.(popup dialog -> select filter ->...)

If you are using LEADTOOLS Multimedia v17.5 .Net DLLs, you can select a video processor programmatically by using the following code:
+--------------+
Private Crop As New LMVCropLib.LMVCrop
...
CaptureCtrl1.VideoDevices.Selection = 0
CaptureCtrl1.Preview = False      

CaptureCtrl1.SelectedVideoProcessors.Add(CaptureCtrl1.VideoProcessors.Crop)

Crop = CaptureCtrl1.GetSubObject(Leadtools.Multimedia.CaptureObject.SelVideoProcessor)
Crop.Left = 10
Crop.Right = 10
Crop.Right = 500
Crop.Bottom = 500
Crop.Enabled = True

CaptureCtrl1.Preview = True
+--------------+

Thanks,
