I am using
void diaryListView_MouseMove(object sender, MouseEventArgs e)
{
ListViewHitTestInfo lvhti;
lvhti = diaryListView.HitTest(e.X, e.Y);
ListViewItem item = diaryListView.GetItemAt(e.X, e.Y);
}
to ascertain which row I am over in a sortable ListView.
How can I search through a dataTable for a match for all the columns in the ListView row please?

we devlop program for big ISP company
have 3 SQL table
Provider Table [Combobox1]
ID Name
1 prov1
2 prov2
3 Prov3
////
Location Table [Combobox2]
ID Name
1 Loc1
2 Loc2
3 Loc3
////
End_User Table [Listview1]
ID Name Provider_ID Location_ID
1 ab 1 2
2 bc 1 3
3 cd null 1
4 de 2 null
////
Actually we add "All Provider" to provider combo also "All Lcoation" for location combo to get all even null. value for both "All Provider" & "All Location" set to 0
I can get fill listview user with specific provider
like
var user = from s in db.End_User
where s.Provider_ID == comboprov.value...
slect s
foreach(.......
this good if all location slected in comoboboxlocation or nonvalue select)
i need to fill full four condition in this one statement for Linq to sql
A- prov = 2 & Loc = 0(all)
B- prov = 0(all) & loc = 1
c- prov = 1 & loc = -1(nothinselect)
D- prov = -1(nothinselect) & Loc = 3
something like
var user = from s in db.End_User
where s.Provider_ID = {"*" @(if combopro.value == 0) || combopro.value} + {s.Location_ID = {"*" @(if comboloc.value == 0) || combopro.value}
select s.
foreach(.......
Thank you...

Hi
If I develop a dll that deals with most of my data security in C++ or Delphi for example, a malicious user could replace it with a bad copy and this way it would void my security.
Is it the same in C#? When I add a dependency it may run with malicious copies (with the same metadata)?
In other Windows Application I would just check the dll CRC before using it... Would that be enough in C#?
Thanks,
Dirso.

.NET assemblies can be signed, that prevents tampering like this.
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - out now! ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

Looks like a nice solution... Let me see if I can work it out 
Thank you so much!!!

Other than the signing that was mentioned in the other post to your question, you can use an obfuscator. With an obfuscator you can scramble an assembly so that it cannot be decompiled and obfuscation also allows you to embed watermarks that you can check when an application starts. (All of this, of course, depends upon the obfuscator you use). I happen to use Spices Obfuscator from 9rays.net, but the company seems to be dying so I wouldn't look into getting that particular obfuscator.

That would be nice. I hope to find something cheap... I use Aspack for years and it was always a good product, but sadly it works with native windows applications only.
Thanks,

Hi all!
I am just playing around trying to learn more about C# and I wrote the contents of textBox1.Text to a file on my hard drive using System.IO, the following way:
string[] lines = new string[] { textBox1.Text };
string filepath = "C:\\Users\\Jase\\JTS\\myfile.txt";
File.WriteAllLines(filepath, lines);
..And it works perfectly. But when I started to type the word File (at the beginning of File.Write AllLines.) the IDE IntelliSense thing popped up and I noticed there is an Encrypt option. Then it got me thinking... Does this actually encrypt the file? I tried the following code to encrypt but does not work:
string[] lines = new string[] { textBox1.Text };
string filepath = "C:\\Users\\Jase\\JTS\\myfile.txt";
File.Encrypt(filepath, lines);
Does anybody have any thoughts/ideas/suggestions? I've looked on Google and MSDN and some other forums and haven't found anything that helps. I'd appreciate any help that I can get  .
Thanks for readin'.
j.t.

Have you looked at the documentation?
MSND Library: File.Encrypt method[^]
You can't use the Encrypt method instead of the WriteAllLines method. You use the Encrypt method on an existing file, so you have to save the file first.
Despite everything, the person most likely to be fooling you next is yourself.

Thanks for the reply I have checked that page several times but I can't use any of the code that's on there. Everytime I debug, I get about 20 errors. No matter what I change, or remove I get more errors. I ended up trimming most of the code down to:
private void EncryptFileLickLabel_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
try
{
string FileName = "C:\\Users\\Jase\\Documents\\jt.txt";
File.Encrypt(FileName);
}
catch (Exception)
{
}
..The file already exists, but it still won't work.

j.t.

What do you mean by not working? can you explain?

Login to some other user account and try to open the encrypted file? File.Encrypt will encrypt the file and give access to the user account where this code is executed. AFAIK, this works only with NTFS file system.

Thanks Navaneeth,
I just tried doing that, but it just won't encrypt the file.

Do you fulfil the requirements of the method?
From the docs: "The current file system must be formatted as NTFS and the current operating system must be Microsoft Windows NT or later."
I'm guessing your drive isn't NTFS

Are you expecting encrypt will make the file unreadable when you open it? AFAIK, the user who encrypted the file can still view it. Try to open the same file in another user account. Also make sure your file system is NTFS.
