I have a winforms control with a website loaded in there.
The website has a flash file loaded (a big webbrowser game) and I wish to know wether it be possible to "hack" into that flash game and send it commands.
Like, there's a button in the flash game which I want to click by using C# code.
I have tried messing around a bit with the shockwave player control but I didn't get far on that.
If it is possbile, I would like to get a small start or a point in the right direction on how to start working with this.
First of all you should have the swf source code: the swf is compiled code. Then, you should add code to the source and, using ExternalInterface, you should expose some functions/methods to the cointainer.

I was wondering if there is a possibility to combine an AIR application with a WinForms Application?
Example
I've made some nice animated loading screens / splash screens with Adobe AIR and i want to use them with an .NET program, is that possible?
I don't want to simply call the program executable file (program.exe) within Adobe AIR (Air.exe). I want to use the textfields inside air, and as I click on Submit, I want AIR to pass the information to the .NET C# form and do stuff with that.
What is the proper way to do so, or what are alternative ways? (using WPF to embed a flash (SWF) inside .NET)
Based on the content posted in this tutorial, I think that it's possible to use .NET with Adobe AIR yet I'm not really sure.
You might also like to take a look at this which shows how to use CommandProxy to integrate AIR and .NET
Thanks,
I hope you find this helpful :)
I'm building a Windows Forms application in VS 2010 that smoothly increases or decreases the speed of a video playing back based on the speed of the user input.
I've tried several avenues..
1.) Using the AudioVideoPlayback DirectX class - I set the speed of the video, by setting the current position of the video, based on a timer.. and increased or decreased that value based on user input. While this worked on my PC, it lags a lot on our lower end target PC's. Can anyone think of a more efficient way to increase/decrease the speed of playback using this class?
2.) I've tried the Windows Media Player ActiveX control, and tried setting the rate/position dynamically, but this is extremely jumpy and laggy even on my development PC
3.) I've tried the Apple QuickTime Control 2.0 COM Component that comes with VS 2010, and it's also very laggy.
4.) I'm trying to figure out how to set the speed on the Shockwave Flash Object control, but haven't found that out yet
Can anyone suggest other avenues to explore? I just need to be able to increase/decrease the speed of video playback smoothly based on user input without lag. I don't care what format the video needs to be in, all videos can be converted to the required format.
Any help/ideas will be appreciated.
Thanks
The ultimate way is to decode the Bitmaps from videos, and handle the frames yourself.
Try the CaptureNET example from DirectShow.NET. It allows you to capture bitmaps from each frame. After that, write your own playback control to handle the refresh rate.
After trying many different formats/libraries and components I found the VLC Media Player ActiveX control to be the most efficient method to slow down/speed up video without any noticeable lag.
I'm using DirectShowNet.dll to grab a photo
of my web camera.
Anytime my camera initializes it first shows me this
screen. Where can I turn it off?

Looks like your code is pulling up the prop pages for your camera. I have only been able to get this property page to show if I explicitly write code to do it. How are you getting the image? Graph -> CaptureGraphBuilder2 + SampleGrabber -> SampleGrabberCB?
You could use the Win32 FindWindow command to find it and then send a WM_COMMAND to press the OK button?
Edit: Well if you want to do it the more "proper" way (Though my experience is from the C++ end, but I assume its much the same) you may want to locate the video capture filter. Once you've located that you can query interface it to see if you can access its IPropertyPage (IIRC) interface. If you can then you should just be able to call Deactivate.
Alas I don't have access to a webcam at the moment so I can't check on how exactly to do this ...
Are you using the ICaptureGraphBuilder? If so it may well be worth learning how to enumerate all the devices and attach them together yourself. It will give you a MUCH better understanding of whats going on :)
We have a few flash files f1.swf, f2.swf .... fn.swf.
We would like to be able to display a slide show of these different files in c# using winforms.
Each flash file is a slideshow by itself. At the end of slideshow for f1 we need to display a message and ask the user to repeat it or continue. Just wondering if anyone has any suggestions how to achieve this.
Thanks

I think this is what you're looking for: How to Play Flash (SWF) inside C#
EDIT:
also here is some interesting stuff: Example C# Code for Reading Flash (SWF) Files
I want to play an audio file whenever my page gets loaded onto the client browser. And if a user presses a pause button on the web page then the sound gets paused until he leaves the sound and can resume as well. ?
Here's some examples. But as some said before, its not the best idea to have sound. But if yo do at least have a toggle to mute, turn the volume down or disable it totally.
The easy musicplayer for flash is a easy-to-set up MP3 player solution that does what you need. It provides "play" and "pause" buttons.
Until HTML 5, flash is going to be your best solution, this is mostly because it's an intrusion to have a page commandeer control of the user's speakers, and thus why people have recommended not doing this at all or making it so that the user must explicitly click something.
Here's a page with some freebie flash player options:
http://www.premiumbeat.com/flash_resources/free_flash_music_player/
I found this web site helpful for setting up a sound file from within a page. In my case, I only wanted it to play if they clicked something. I would agree with others here who suggested that.

One problem I have is when I have a number of web pages open and one of them starts making a sound, it is very difficult to find the page to get it to shut up. It is better to have the user launch the sound.
I guess achieving the same with jquery plugins won't be less exciting!
The jquery mediaplayer does the same. Using this jquery plugin, you can play your media player files without the need of windows media player. The limitation is that this works only with the media player type of files.
Further, since mp3 files are highly used in web pages, we could use the bssound jquery plugin to embed mp3 file in our web page.
