Hello Ishtiaque,
It seems you're new in CP, am I right? 
So, take a look at the first post in page 1 titled "How to get an answer to your question" by "Chris Maunder". There are several great articles here in CP also, like CodeProject Forum Guidelines[^] by Scott Dorman or Some guidelines for posting questions in the forums[^] by Pete O'Hanlon. They will help you posting your question.
For this question, you better ask it in ASP.NET forum or Php forum.
Good Luck

Hi!
I'm working on an application which will need to insert text into a RichTextBox where the user is currently writing. But to do that I need the index of where the text marque is. Does anyone know how to insert some text into the a RichTextBox where the text marque is or how to get the index position of the text marque?
(I don't know what it's called, therefore I call it text marque. I mean the thing which is in front of the text you're writing in e.g. a RichTextBox)

It's called the "caret". The property you're looking for is SelectionStart.

You should contact the company directly and se if they have an API. If they don't, you may have to use amy built in export/import functions to make the data .net accessible.

I want to write a program in C#.
This program prevents specified files from being deleted.
Anyone can offer some ideas?If you'd like to provide part of code,it's better.
Thank you very much!!

If your program holds on to the file by having it open then the file cannot be deleted.
|
|
|
|
|
It also may prevent any/all access to that file.

Even less chance of the file being damaged then.

This doesn't sound like a very nice program. The files on a computer are the user's files and they should be able to delete them if they wish so long as they have the necessary credentials. Most of us have had to deal with 'undeletable' virus and/or spyware & adware files at one time or another and they are a PITA. I can't imagine why you'd want to add this 'feature'.

I'm sorry,I'm sure that you(DaveyM69) misunderstand my idea!
I have some very important files.Certainly,I don't hope that other people delete them by mistake.
However,thank you all the same for reply!

Google "C# file permissions" for lots of ideas and code samples.
Also, for .NET 2.0+, see the FileSecurity Class[^].

A lot of hostile answers, as it is not the 'polite' thing to do. Users want to control their computer, and they tend to get upset if the computer dictates what they should do.
The nice way of protecting users against accidental deleting would be called a backup-technique. You simply make a copy of the file when the user marks it as 'important'. If someone deletes it, you can always restore the file from your backup.
Good luck

That's not gping to work since the FSW only reports things that have already happened and will only work so long as the app is running.
|
|

That's up to the users to determine, not you or your code. You really can't do what you want unless the user creates a special user account your app has to use that modifies permissions on the files. That way, the permissions get copied with the files if moved to other NTFS volumes and are also backed up during a tape back up. This special account requires its own user name and password that your code would have to manage and generally makes your app more difficult to support in the long run. Not worth the effort...

Look, it's extrememly unlikely you're ever going to get an answer to this question, no matter how many times you ask it, simply because of the obscurity of the information you're looking for. There are very few people on the planet that have ever messed around with the old OLE file format of Word.
If you want the file format, you can look at this[^].

Hi,
When should i use this:
protected virtual void OnEvent_PageMenu_Info(string msg)
{
if (Event_PageMenu_Info != null)
{ Event_PageMenu_Info(msg); }
}
and this:
Event_PageMenu_Info(msg);
Sometimes i use one or the other but dont know why 
Thanks

Assuming Event_PageMenu_Info is an event....
What happens if you raise the event before checking for null and
there's nobody subscribed to the event? NULL reference exception 
If you've implemented a OnEvent_PageMenu_Info(), then that should be used
to raise te event.

He could add a do-nothing event handler inside the class that throws the event so that the invocation list is never empty.

I found a neat trick recently - can't remember where.
You can add a dummy handler when declaring the event:
public event EventHandler<...EventArgs> MyEvent = delegate { };
Then the event is never null.
