Hi,
I have created a windows service which monitors the activities of files on the server. This windows service is using a filesystemwatcher.
Every time there is an activity, i.e. when a file is moved or created, etc., then the system sends an email.

All works fine.

Question:

Imagine something will have to get installed on the server and the user forgot to turn off this windows service. Then as a result, a lot of emails will get sent.
This is what I am trying to avoid (Sending un-necessary emails).
Ideally, the user will turn this windows service off but what if he doesn't? certainly we do not what the system to send so many emails as the result of something being installed which can cause alot of files movements and creations, etc...

Thanks

Well, if you were stupid enough to set the folder to C:\ and then allow it to watch subfolders for "*.*" as well, you deserve what you get.

How about this... write the service to be more selective about what it's watching for. I know, this might be a huge mental leap for you, but sometimes, programming requires, ummm...., programming.

What would you do if someone decided to copy 500 files from somewhere? You need to reconsider your requirements and design.

Hi,
That will not happen as this system will be used for files which are not supposed to be changed.
Thanks

I think what you mean is

That should not happen as this system will be used for files which are not supposed to be changed. Smile | :)

Anyway, back to your original problem. AFAIK an install is the same as copying files (at least to a file watcher), so how about seeing how many changes there are in say 30 seconds and send a single email out listing them? Not a perfect solution but maybe a viable work around?

Hi,

You can do this using XSLT and XPATH but if the HTML you want to parse is in XHTML format.

How to create setup for C# Windows Application exe. I have tried uisng the Publish option in the application. The problem is with database path. I have put the database(.mdb) file in a separate folder called database. So in the ConnectionString I have given the database path as @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source =" + Application.StartupPath + @"\Database\dbCIMS.mdb;"

How do I include this database in the Setup using the Publish wizard. When I run the setup it was giving Invalid database path error.
Please help

Wild Card Search

Hi,
I have a textbox in which i want to implement wild card search. Like if i enter one char 'A', all the names starting with 'A' in database for that table should be listed. If i enter two chars, correspondingly data should be listed. Can anyone please tell me the solution? Code is in C#

Your problem shows there must be a table in your database which you want to target.If you are using that text box on ASP.Net page,
Try this one:

string searchkeyword=yourtextbox.text + "%"; (special character is for use with stored procedure)

stored procedure:
create procedure searchwithkeyword
(
@keyword nvarchar(50)
)
as
select names from yourtable where name like @keyword

now the code for button click event:

sqlconnection con=new sqlconnection(yourconnectionstring);
con.open();
sqlcommand com=new sqlcommand("searchwithkeyword",con);
com.commandtype=commandtype.storedprocedure;
com.parameters.addwithvalue("@keyword",searchkeyword);
sqldatareader dr=com.executereader();
if(dr.read());
{
//display results
}
else
{
//show message
}
dr.dispose();
com.dispose();
con.dispose();

The code is a bit messy as it is not implementing try catch and finally blocks but if it is worth helping do that yourself and let me know what happened to your problem. Smile | :)

You just do something like:

string searchstring = "%" + textbox.Text + "%"

and pass this search string as a parameter to a SQL LIKE in the WHERE clause, which will result in something like this:

SELECT id, name FROM users WHERE name LIKE '%A%'

But make sure that your app won't be vulnerable to SQL Injections[^].

Using List?

dipuks24-Jul-08 16:20

I have a List declared as,

List<string> myList = new List<string>;

myList.Insert(0, "One"); // this line works fine.

myList.Insert(1, "Two"); // This throws an exception, saying the index should be with in the range.

What am i doing wrong here?

I want to add the string in a order to the List. And this order i decided on the run time of the program. So i don't wanna use the "Add" method.

Re: Using List?

The Insert method doesn't work that way. MSDN[^] clearly states that if index is greater than Count, you will get an ArgumentOutOfRangeException exception.
