Capture A Bitmap From A Firewire/Camera Source?
Aug 6, 2009
I have a firewire and a camera. I can see the video as in a preview using tools like MS Movie maker.I want to write a simple program that allows a Preview and when a button is clicked, grabs the snapshot bmp,jpg.I have written a program that works with a webcam and a usb interface. It uses capCreateCaptureWindowA
But this technique displays a blank screen when trying to capture a WDM device. So i am back to square one. There must be a snippet of code out there somewhere to do this.

There is Bitmap data on the clipboard from a screen capture. If I paste it into a RichTextBox it works OK. That is, if I remove the first two lines below.
Dim clipboardDataO As DataObject = CType(Clipboard.GetDataObject(), DataObject)
Clipboard.SetDataObject(clipboardDataO)
RichTextBoxTxt.Paste(DataFormats.GetFormat(DataFormats.Bitmap))
However, If I capture the clipboard data and restore it before I paste I no longer get my bitmap displayed in the box. My problem is, in the real situation I need to use the clipboard before I paste which is why I save it and restore it above.
1) Do you know why restoring doesn't appear to work here?
2) I can't paste before the save/restore. Is there something else I can do?

I've got a function that's supposed to extract and return a 32x32px bitmap from a larger bitmap which has a set of 32x32 tiles inside it.
Here's the code I have now, but it's wrong since the Tile.GFX_Pos properties are telling it where in the destination image to draw, not where in the source image to draw from.
Overloads Shared Function TileGFX(ByVal SrcGFX As Bitmap, ByVal Tile As TileDef) As System.Drawing.Bitmap
Try
[Code]....
So since this doesn't work, what I'm wondering is if anyone knows a good way to select where in the SrcGFX bitmap to blit from, instead of (as currently and incorrectly) selecting where in the destination bitmap to blit to.

I think that changing from WinForms to WPF just because the blur effect is easier to do in WPF is the stupiest thing i can do right now it took me time to understand how the windows form application works i dont even how change the source of an image in WPF so here we are again. how to blur a speciefied image using CODE ONLY ?
See what im trying to do:
1. Imagine that you turn on your pc. takes some time to load.
2. Finally for the first time you are on the desktop.
3. Before you do something after every icon is loaded my program
takes a picture of the desktop and blurs it.
4. then it runs fullscreen showing the desktop behind as blurred and
not giving you access to the desktop.
5. a login/register border pops up
6. if you login the program closes if you dont it stays there
waiting for you to login or register.
I wont use it that way im planning to do it on the startup of my program only blur the window not the screen (i mean the content of my window) untill you login or register then it clears again. What i need to learn:
1. How to take a screenshot of my program (only yhe content of the window) [Progress: 1% (cause i know how to take a screenshot of the desktop)]
2. How to blur that image [Progress: 100%]
No need for third party programs or dlls i mean isnt there a default function in vb.net the stupiest way to do it?

Here is a short program to demonstrate my question. I just want to extraxct a rectangle bitmap from a big bitmap.Code as follows:
Private
Sub Button3_Click(ByVal sender
As System.Object,[code]....
Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:
"MissingMemeberException was unhandled.
No default member was found for type 'bitmap"
I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

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")

How can I take pictures using a digital camera based on a button click in WinForm application? I tried googling, and got WIA. Used WIA 2.0 and wiaut.dll, and it is working fine for webcams. But I am not able to automate the actions of my Sony W220 camera. I tried googling for WPD, but it appears to be active only in Windows 7 and Vista, and I am using XP Sp2

I want to write a .NET application to show and save video streams from an ip camera. But I'm not yet sure what would be the best way to get started. Should I look for an Axis camera so I'd be able to use their api or will I be fine accessing the video stream using directshow or whatnot using any other camera ?

I don't know what this is called so I've struggled to find an answer from google but I have a vague memory of it from t'old days.I've sub-classed (* see below) about 8 framework controls, overriden some properties and added some functionality into each one.The changes I have made are identical in every case. If I make a change, I have to go through each class and apply the same change there.I was hoping there may be a keyword such as <IncludeSourcefile "common.vb> that I can put into each class.
(* note) I use the term sub-classed but I don't know if that's the correct terminology. I've also seen it used for call-backs. Is sub-classed the correct term to use?
