• SQL Server Encryption Best-Practices

  Please forgive me if I have overlooked a thread that answers this question, but I assure you that I have looked. I would really appreciate a guide of sorts that would tell me the correct steps to take to properly secure a column in my database. I don't need specifics on how to do each step, I either have those already or can find them myself. In fact, I have already successfully encrypted and decrypted some data. I just want to make sure that I create the right keys and certificates and that I follow best-practices as far as backups and stuff is concerned. Thanks, Todd Sparks Here are some suggestions: - if you will need to ...Show All

  Hi peeps. Iam completely new to all this. I belong in a macromedia world of flash. lol. But I though I would come see what all the fuss is about and downloaded myself a copy of visual web developer. It looks a really nice program and really powerful.

• Windows Forms Retrieve data from listbox

  hi, here i have one listBox1 and populated it (using listBox1.Items.Add()) with data from two columns (name and email address) inside a datagridview. There are about hundreds rows of data and the listbox is meant for displaying whatever user has selected inside DGV. Now, with a click of a button, I want only data from one column (email address) to be inside a textbox, separated by commas. My code cannot call up all email addresses inside the listbox1. It only returns the correct number of items inside listbox1 but keep on repeating same value. Fyi, i set listBox1.ValueMember = emailaddress; here are some lines from my c ...Show All

• .NET Development Missing indexing methods for SortedDictionary?

  I have a fairly standard data structure need: a sorted collection with fast insert, delete that can be accessed efficiently by key and by index. The SortedList has O(n) insertion so the closest is the SortedDictionary but it has no means of indexing. Why not This should be the difference over a standard Dictionary that you can easily perform operations like head and tail. I would expect the method RemoveAt, GetAt etc like the SortedList. The SortedDictioary.ValueCollection seems next to useless. You can foreach it but not index it. Am I missing something thanks in advance, Duncan No, you're not missing ...Show All

Thx A char in .NET is 2 bytes. A string is essentially an array of chars.
