How to detect if any video is being played now using autohotkey, autoit, vbscript, c#, or c?
Video could be being played/streamed in any local player, web based player, or html5 player. We do not know the name of player also player may not be in the full screen.
PS. Detecting CPU load may not give the correct result always, so it is not acceptable.
I've done a small bit of work on this back in the day. There is a WIN32API (old school) that gets/sets whether or not to disable the screensaver (in user32.dll, GetScreenSaverActive(), SetScreenSaverActive - see: http://www.codeproject.com/Articles/17067/Controlling-The-Screen-Saver-With-C). This is the most likely flag to be set when a video is playing but it not 100% reliable as not every player will implement it. It WILL work for most browser videos, whether played through plugin, natively, or via DirectX. This also works for most (all?) external players such as vlc, windvd, etc.
But.
There is no sure-fire, 100% way of determining a video playing. You cannot;
1. Check for sound playing as the user may be using iTunes and not all videos have sound
2. Check for full screen (usually the better option) as the video may be playing in a browser
3. Check cpu/gpu load as it's not reliable and you have no other way to determine
4. Be absolutely sure that the player hasn't cleared/reset the win32 flag when minimized
Another option would be to try and collate a list of possile executable names for all known players (doable but time consuming to find data, espesially on older versions), and check to see if they're running. This isn't 100% reliable either as a plugin by be preloaded but a browser but not actually playing a video at that moment in time.
In short, there's no 100% way that I know of but several ways that'll get you 90-95% there. That is the purpose of knowing if there's a video playing? Perhaps there's an easier way to find what you're looking for...

I need a digital typeing sound effect.when numbers are typed,Sound effect appears in background of the video.I want to make a program that when I press the keyboard, I also listen this sound effect.How can I find this sound effect or take from this video?
the sound effect between 0:50 and 1:15

For the 'extracting the sound effect' part of the question, you would likely want to use an online video/audio downloader/converter. In the past, I have used youtube-mp3.org and clipconverter.cc.
For the second part of the question, it depends what exactly you want. If you want it to apply only to a specific text box in a WinForms/WPF/UWP app you are writing, this should be reasonably easy. The exact method depends on what you are doing, but involves adding a keydown, keyup, or keypress event handler to the text box
If you want it system wide, this is more difficult. Searching for 'Global Keyboard Hook C#' appears to give good results.
Once you have detected the key press, have a look at this question for how to play the sound. The answer by bporter gives the following code:
System.Media.SoundPlayer player = new System.Media.SoundPlayer(#"c:\mywavfile.wav");
player.Play();
Use this to convert the video to mp3. Clip the sound effect out of the mp3. Then play the mp3 file with your code.

For my college project, I have decided to create a rhythm game which is similar to Beatmania, with notes falling from the top of the screen to an area where the user needs to make an input.
Now, for the main menu, I would like to include a visual equalizer, with bars moving up and down in rhythm with the music that is playing in the background:
This would need to be customisable to be added into the main menu (transparency so that background behind the bars is visible etc.
Currently, I have been looking all over the internet to try and find a way to program such a thing. However (unless I'm using the term wrong), all results come up with actually equalising sound based on bass etc. and since I'm somewhat of a C# beginner I am baffled as to what is said.
XNA Visual Equalizer Video - this is the closest thing I have found to what I would like. Unfortunately, I have no idea how to use XNA and there is a chance that my college will not install XNA, so working on the project will take longer, as I can only work on it at home. So Windows Forms would be preferred.
Any input on this would be appreciated. If you have any questions then please ask :)
Edit: (Not sure how to narrow this question down) - I need a Visual Equalizer in Windows Forms, does Windows have such a method, class or reference that can be used right off the bat without having to download plugins, extensions etc.?
What you are looking for is called an Audio spectrum analyzer. XNA is commonly used in games, and should just be included as a .dll in your files. I don't think you have to install that b/c you can publish XNA content as a native executable.
However, instead of reinventing the wheel, the nice folks at code project have shared a project that analyzes the frequency of sound. You should be able to modify this and get it to work to your specifications.

I want to start a web project in which:
User first signs up.
Uploads his desired favorite image to website.
Selects which action, filter, plugin or even photo editing feature he wants to be applied to the image and the solution came to my mind is automating Photoshop, I mean user submits his request to the server and server opens up Photoshop and automatically applies the desired operation through Photoshop to the image uploaded by user and saves and returns back the result to the user.
Now the problem is that how can i do so and automate Photoshop through ASP.NET or PHP.
Any solutions appreciated.
The very first thing you need to check out is Adobe's licensing on using Photoshop in this fashion.
Once you've addressed any licensing concerns, it would be fairly straightforward to automate. You need to write the actual photoshop automation part using Adobe's ExtendScript (a flavor of javascript) to do the image manipulation you want. If you include the line '#target Photoshop' at the top of this script that should take care of making sure Photoshop is automatically launched when you execute your script from ASP.NET or PHP.
Chances are you'll want to pass parameters to your scripts - and the only way I am aware to do this would be to write them to a parameters.xml file in a predefined location so that the script can read them in from there. I do not think you can supply them directly when you call your script.
You won't have a good way to tell when Adobe is finished with the image. The best thought I can come up with off the top of my head is to predefine an image drop location and have ASP.NET/PHP poll for the resulting image occasionally. Depending on what you are doing, and what size images the manipulation could take a significant amount of time - you may want to come up with an alternative solution.
ETA: From .NET you can also automate photoshop more directly via its COM interface. You'll need to do a bit more research to get it working, but this link should get you pointed in the right direction.

I have a C#/WPF application that displays collections of components. I want to know how to create an image that is styled like the Windows 7 folder icon, where one or two of the content thumbnails are enclosed by a yellow leaf folder. (The collections I have aren't real Windows folders, and their contents aren't real Windows files)
Google Approach
I have spent a fair amount of time searching for code samples on how to do this, or anything even remotely similar. I can't find a single example of anyone doing this, which has truly surprised me. It tells me one of two things:
I can't find the right keywords to search on (combinations of: thumbnail, windows, c#, wpf, icon, folder)
Nobody else has ever wanted to do this, and that's because there is a better way of doing what I want to do.
Coding Approach
I can see that there might be a back image drawn first, and then skew transforms applied to each content thumbnail, overlaid, and then finally the front image. I've seen some code examples that show how to skew images, etc. There are some very subtle effects being drawn here too (shadows), though they could be "canned". I'm not sure how to separate the example images below into a front and back portion, though I could give it a try in Photoshop.
Windows API Approach
The closest approach I've been able to find without coding this from the ground up is to write a component's thumbnail to a real Windows .PNG file, inside a real folder, and then use Windows.Storage.StorageFolder.GetThumbnailAsync() to get Windows to do it for me. Obviously this makes me die a little inside, but it might be the quickest way to do this.
Can anyone help me? Ideally I am looking for a library or existing code sample that could show me how to generate these. Otherwise, I will attempt to code this myself using the coding approach outlined above. I'm not looking for someone to write this code for me, but I would appreciate any pointers.
Thank you!

I have an WPF application that starts a live tv recording using Windows Media Center, using the Windows Media Center SDK, waits 2 minutes and then plays the currently recording file (.wtv) in a WPF MediaElement. The problem is that the video visual will freeze and it is not consistent on when it happens. I have looked into it and discovered that the timeline is still moving so the MediaElement still thinks that the video is playing.
This happens only when trying to play a video file that is currently being recorded, previously recorded shows play just fine. Both Media Center and Media Player can play those files without any hiccups; it is only the WPF MediaElement that has this problem. Any help would be appreciated.
My guess is that the way the media element works is that it grabs the size of the file it's about to stream at the time you first play it and gets stuck after that. It's just a guess but I have no other information to go off of.
I do know that the MediaElement is really good at switching streams and resuming in those streams. Perhaps there is a work around you can find where every so often it will refresh the stream and resume from it's current position.
This sounds like an MS bug.
You could possible set up an HTTP proxy for the wtv file, then tell the MediaElement to play the stream and not give it the actual size. Its a lot of work but may just work.
