How To Capture A Frame From A DVD
Aug 1, 2010
I have a personal project to complete and one of the smaller aspects is to capture about 10-20 seconds of video or a screenshot (bitmap,jpg, etc)from a DVD. This is made even more complicated by the fact that the video files may be .VOB, .AVI or .MPG and using numerous codecs (DivX, Xvid, etc).
I have searched on google and the tutorials here, but nothing seems to fit.
Does anyone have some "simple" references, URL's, blogs, code examples that would help with my quest? (My policy is not the KISS principal, but the KISFSP ... "Keep It Simple For Stupid People")

Now I do have code already I found online, but it is just using API's like I would in VB6. Is there any .Net code to find if web cam is available, and if so, just take a pic and save to a JPG.
Note, the API methods work however I can only get it to work if I paint it onto a form or picture box. I don't want any forms or picture boxes. I just want .Net code to grab a picture with the web cam and save to file.

While I have got some leads from an older SO post and from this site, I haven't been able to figure out how to capture each frame of a web-cam.
What I would like to do is something like this capture a frame then do some image processing on it and display the output and then move on to the next frame.
Can I can access to web-cam frame events or is there any efficient way to achieve this?

how does this function works. How does it copy the frame? HDC BiBlt???
ublic Function copyFrame(ByVal src As PictureBox, ByVal rect As RectangleF) As Bitmap
If isRunning Then
Dim srcPic As Graphics = src.CreateGraphics[code].....
the above function is called from the below command which is in a timer event. mycam is a class including the copy frame function.
bm2 = myCam.copyFrame(PictureBox1, New RectangleF(0, 0, PictureBox1.Width, PictureBox1.Height))

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

I am writing code to automate internet explorer. I have successfully done it for a few sites, essentially I need to be able to access the html, and elements such as input boxes to automatically fill out forms, and pull back the results. But for the current project the website has a framset and frames, I was wondering if there is a way to get access to the html and elements within the frame.
I am using Interop.SHDocVw to control internet explorer. I have been trying some code similar to the following, but after I get the frame I need and the documentElement off of it, I can't get the actual html inside the frame. I can get the outer page/framset html, but whenever I try to get inside the frame is comes up as Nothing. I was thinking it may have to do with IE frame security

How can I draw a frame or groupbox or panel whose style effect is 'Raised' (See attachment). In most of the cases when we set the Frame or Panel borderstyle to 3D, the style effect is 'Sunken'. But I want it to be 'Raised'. This is possible if you add the reference- Microsoft Forms 2.0 Object Library, choose Microsoft Forms 2.0 Frame from 'Choose Toolbox Items' and set its SpecialEffect property to Raised. But that is a COM component and I want it to be done through core .Net framework components.

I thought I could use this, to loop through all checkboxes in a frame:
For Each cb As CheckBox In Me.frameSearch.Controls
cb.enabled = False
Next
But it walks through once, then it comes with error:
Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.CheckBox'.
There are indeed labels within 'frameSearch', but I thought that the "For Each cb as Checkbox" would loop only through all checkboxes..? Following does work, but it seems a bit of waste of CPU time, since it will loop through all controls!
For Each cb As Control In Me.frameSearch.Controls
If TypeOf (cb) Is CheckBox Then
cb.Enabled = False
End If
Next
How to do this more effectively?
