you have two for loops, only one of them is commented out.

this.lsv_user.Items.Add(lstItems);
}
}
With that, you are adding the same record to the ListView n(sReader.FieldCount) times. Your problem is the line in bold, you are adding the same ID/name ((i + 1).ToString()) for each record. Each ListViewItem should have a different name or be blank (no parameter).
I think I know what you are trying to do, so I hope this helps:
if (sReader.FieldCount > 0)
{
_ID.Add(sReader[0].ToString());
lstItems = new ListViewItem(sReader[0].ToString());
for (int i = 1; i < sReader.FieldCount; i++)
{
lstItems.SubItems.Add(sReader[i].ToString());
}
this.lsv_user.Items.Add(lstItems);
}You just need to replace the content of your while loop.

Is there anyway to do this without closing/reopening the file?
I found this in some code I wrote a few years, and after cringing and hitting google, failed to do so.
m_fsXMLLib = new FileStream(m_fileName, FileMode.Create, FileAccess.ReadWrite, FileShare.None);
m_fsXMLLib.Close();
m_fsXMLLib = new FileStream(m_fileName, FileMode.Open, FileAccess.ReadWrite, FileShare.Read);
My intent is to keep anyone from trying to read the file while it's being written and in an inconsistent state. After saving the file, I want it kept open to prevent anyone else from being able to modify it while letting them have read only rights.

Hi Dan,
interesting question.
IMO a pure .NET solution does not exist. This is what I would try:
- create the FileStream with Share.None
- write and flush the data
- now P/Invoke to CreateFile, specify Share.Read and a zero FileMode (which .NET compiles but refuses to run) as explicitly allowed here[^]
- finally close the original FileStream.
That may run all right and yield a file readable for others.

I am writing a web application that I want to use windows authentication for. The only problem is that the users using it may not always be running it from there own machine. I want to check the roles for the current windows user and if they have the required role take them directly into the application. If the current user does not have the required role I will take them to a sign-on page so they can enter their windows user i.d. and password. Then I will check if that user has the required role. The problem is that I can only find a way to check the roles for the current windows user.
Is there a way to validate the user that signs in to the application rather than the windows user and check the roles or groups they are in?
Thank you
Marty

Use the techniques from this article to impersonate the user given their username and password. Create a new System.Security.Principle.WindowsIdentity object from the token you'll get back from LogonUser. Use my code from this post, where currentPrinciple is the WindowsIdentity you created

Hi, i want to create an application that can be loaded into anyone computer.. But the database has to be consistent, so i was thinking of using my web server mysql database.
but how do i use the database from the application i created?

Use a webservice to communicate with the database and have some sort of authentication system for your client.

Hi,
both subroutines and functions are called methods in C#; they may or may not return one value or reference, depending on the return type in the declaration. Same as in C, C++, Java, and a lot of other languages (except they often are called functions, with or without a return value).
I suggest you buy and study a tutorial on C# so you can reach structured and illustrated knowledge in minimal time.
