Don't prematurely optimise. If you find that this is a performance bottleneck (which I really, really doubt) then you can look for clever tricks.
Often the simplest way is the best. How would you optimise '2+2'?

Often (at least with computers), what at first appears to be simplest is not.

Hi
I'm woundering if there is a way to detect a mouse click in a Word document that I have opened in my Form.
Many thanks

AFAIK if you call Mouse.Capture()[^] the control specified will get the mouse events, no matter where the mouse is going, or what window has focus. But then, if you hover a Word document, you won't be able to select words, set the caret, or do anything to it.

Hi
Thank you for the answer. Can you give me a code example. The only thing I want to know if the users click on the word document.
I'm using these objects
ap = new Word.Application();
doc = ap.Documents.Open(path, ReadOnly: false, Visible: true);
Many Thanks
Fia

I don't have any. I suggest you read MSDN, and use Google. It has nothing to do with Word, Mouse.Capture is a general-purpose tool.

Hi
I'm sorry I haven't found anything that helps me or I'm not understanding the examples. Is there anybody who can help with some code how to do this.
Please
Thanks

Hi 
Thanks for all the replies. I have found a solution.
Microsoft.Office.Interop.Word.Application ap;
Microsoft.Office.Interop.Word.Document doc;
ap = new Word.Application();
ap.WindowSelectionChange +=new ApplicationEvents4_WindowSelectionChangeEventHandler(ap_WindowSelectionChange);
doc = ap.Documents.Open(path, ReadOnly: false, Visible: true);
private void ap_WindowSelectionChange(Microsoft.Office.Interop.Word.Selection Sel)
{
}
When I click in the doc I have opened the event ap_WindowSelectionChange runs.

If your application is running in the user's security context, and it has access to the file, then the user also has access to the same file. If the user's an administrator then you're screwed, from a software solution point of view. The best you can do is (i) keep rewriting it if it is deleted (though this might get you flagged as a virus) and (ii) refuse to operate if the file is not present.

I would guess that it is possible to manufacture a USB drive that was read only.
Basic process would be
1. Find a manufacturer.
2. Set up an business relationship.
3. Create an image.
4. Ship image to manufacturer.
5. manufacturer burns image to usb and constructs device
6. You deliver to customers

It's kinda simple; if you have the USB-stick, you can format it and wipe any data that was stored on there.
If the key only comes near to computers that are under your control, then you can use a setting in the registry[^].
If not, you'd buy a key with a hardware "write protection" lock, (list here[^]) Put your files on there, put it in readonly-setting and glue the button in it's place with superglue.
However, if the file is "crucial" for your system and people's would depend on it, I'd say you need TWO internal SSD-drives and a darn good lock. USB-sticks don't fail often, but once-in-a-million events are bound to occur.

I think you may have to go for embedded programming.Only USB manufactures can do that..i guess.Anyway I just stopped taking flights ...uffffffffffffff

Guessing is a bad form of answering. If you read my post you would have seen two options for the specified scenario.

First let me try to translate the subject of your message for those who neither speak Spanish nor are willing to accept #2 of "HOW TO ANSWER A QUESTION":
"How to protect an XML file so that it cannot be deleted from the computer"
A very simple solution is to make the file hidden (see file attributes http://msdn.microsoft.com/es-es/library/system.io.file.setattributes(v=VS.90).aspx[^]). Of course, that's simple and the user can easily find that out.
You can make it more difficult for the user when you write a Windows service. That would run with "Local System Account" and thus has different access rights to files. A user with admin privileges could still delete it.

Hi,
I have an application build with VS2005 + SP1 on Windows XP + XP SP 3. This application simply copy a file from some folder to "C:\". When I copy my release build .exe from XP machine to Windows 7 machine. It does not copy the source file to "c:\" I am using following code to copy my file.
class Program
{
static void WritetoLog(Strings)
{
System.IO.StreamWriter file = new System.IO.StreamWriter("D:\\Test\\CopyFileApp.log", true);
file.WriteLine(s);
file.Close();
}
static void Main(string[] args)
{
try
{
File.Copy("D:\\Source.txt", "c:\\target.txt", true);
}
catch (Exceptione)
{
WritetoLog("got Exception");
}
}
}
Surprisingly, there is no exception on Windows 7 and neither there is file copied. Please let me know what is wrong here and if there is any workaround to this. If I build the same application using VS2008, I get an exception on Windows 7. I am working on a big application and can't move to VS2008.

This is your issue. Your StreamWriter is set up to write to D:, not C:
I wasn't, now I am, then I won't be anymore.

The problem is not with StreamWriter. It is with File.Copy

Does D:\Test exist? If not, your logging code will fail and the whole thing will exit with an unhandled exception.
