If this is your first project, you really shouldn't be attempting something like this. What I have described is hard to do properly and will not fit into a single forum answer. You are going to have to implement threading so that you don't block things while you do the read/draw/write operation. You have to understand how to work with video. Assuming this is in realtime, you need to understand DirectDraw.
And no, I don't just hand over code. If you search in Google, you might find an implementation, but given your inexperience, I don't think you'll understand it.
Pick an easier topic to start your C# programming career with. If you don't, I suspect you will become disheartened and that would be a shame.

Using code. Find a programmer, maybe (s)he'll write some for you.

There you are;
Console.WriteLine("Hello world");
If you need more code, I suggest you learn to WRITE it, or HIRE someone who can. No-one is going to write your work, based on your wishes, "just for the fun of it".

Please read How to get an answer to your question [^] Specifically item 1. Also, in general, it helps to add what you have tried and what is going wrong, otherwise people here will assume you just want the code written for you. If you are having problems getting started, say so though a quick Google search[^] has at least two results that should get you started, so I doubt that is the case here.

Hi,
I wish to start and run an application automatically.
I can create a task in Task Scheduler (It's still called this in Vista, don't know about windows nt, 7 or 8) to start the application daily at a specific time. No problem.
However, I actually want the app to perform some functions.
I'm thinking that passing some command line parameter through to the app when it starts through the task I've set up but a) I'm not sure how to do that
in Task Sceduler and b) hot sure what code I need to include in the application to pick up on the command line parameter.
I'm using c# 3.5 and viz stud 2008 and i guess it's a winform application at the mo too.
thanks
Mat

Picking up command line parameters works the same for all; you have a main-method, and if correct, it'll have an array of string that hold the params.
Take a look at the example here[^].

Hey thanks,
command line args 101...it's just been ages since I've had to use them. Task scheduler also has a property for adding the command line arg as well..so job done, cheers

suppose I have the code was inserting records into the file c: \ \ test.dat see the code http://www.koders.com/csharp/fid4FB06ED9F7F6AA6BB805F9152B3DB29BBD1D0C61.aspx?s = CDEF% 3Afile
ith now want to delete the records in the file c: \ \ test.dat I can copy the code
btnAppend_Click to delete sample letter how i
code:
'Add items
private void btnAppend_Click (object sender, System.EventArgs e)
{
....
sf.Open (System.IO.FileMode.Append, System.IO.FileAccess.Write, System.IO.FileShare.None);???
...
}
'Delete the ith sample
private void btnDelete_Click (object sender, System.EventArgs e)
{
....
sf.Open (System.IO.FileMode.Append, System.IO.FileAccess.Write, System.IO.FileShare.None);???
...
}

The steps are generally pretty simple. Read the file in, and look for the record you want to delete. Delete the record. Save the file back out.
What, exactly, are you having trouble with?

Looks like a spooky way to serialize something. I suggest you use a BinaryFormatter, and use a Collection to manipulate the data.

for example: add, delete, edit, ... struct binary record form and load the data into the listview? I'm using C # 2005, if you share yourself with, thank you

Same way as for a text file.
1. Open file
2. Read to just before place you want to delete.
3. Mark that spot - call it A.
4. Read to just after you want to delete.
5. Keep reading but as you read write back to position A (incrementing A as you go of course.)
6. Keep going until you reach the end of the file.

I would like to know when a program was installed on a remote machine.
I can read HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\[XXXXXXX] remotely, but I can't seem to translate the UninstallString into a date remotely via MSIGetProductInfo, so I then tried to see if I could read the keys last modified date via RegEnumKeyEx and did not have success there either. If anyone knows how to do this, I would be very appreciative, I cannot find a single working example of RegEnumKeyEx so that I can plug in a server name, hive, path and key name to test with.
Thank you for reading.

You could remove half of those cases by normalizing the capitalization. Do a ToUpper and the code will be a bit smaller/easier to read.
