View 6 RepliesIn VB 2008 - Is there a way to capture the value a splitter is set to? Here's the scenario - 2 panels side by side. Panel 1 has a splitter - Split1 houses a tree view and Split 2 houses documents in the tree. Is it possible when a user resizes that splitter to grab the value and set as a default? Also, I am only able to get the splitter to be 50/50 no matter the real estate it's consuming... is there a way to preset that size and shrink the outer panel within an event so panel 2 can consume that realestate?

I have the following code found on internet:
Const WM_CAP_START = &H400S
Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:
'---save the video data into the Image global variable---
Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---

The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.
