Storing And Retrieving Encrypted Contacts From Or To Treeview
Jul 21, 2009
I have an application which saves contacts from Outlook/Csv onto a disk, from a Treeview. Now I want to provide security for this file. I want to provide encryption using AES algorithm to the file before it is saved on the disk. My problem here is how I encrypt it before saving the contents from the treeview into the file on the disk. Also I want to decrypt the file contents and load treeview if i find the file is encrypted.

I basically need to hold a lot of data - the structure is that of a five dimensional array holding integers.What would be the most efficient way of storing this in a file (I was thinking of XML - your opinion?) that would also be quick to extract.

Here is the code I used to store an image in my database (SQL Server 2008 R2) using VB 2010. The images get stored but the problem is the clarity of the image is lost when retrieved and seen in a picture box.
Public Function InsertUpdateImage(ByRef _SqlConnection As System.Data.SqlClient.SqlConnection, ByVal _Image As System.Drawing.Image, ByVal _ImageFormat As System.Drawing.Imaging.ImageFormat) As Integer

Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.

I have been working on an application that has a built in contact database.I would like to be able to syncronize this with Outlook.
Specifically:
1)Bring Contacts in Custom App over to Outlook
2)Keep info on those contacts syncronized in Outlook and Custom App
3)Ignore contacts that are in Outlook but not in Custom App(ie do NOT bring them into custom App)

I want to create a simple treeview from a database table. It is going to be recursive and I want for each item to show the description and in the background of each item hold a key value. Then when the user selects a node I can use that key value to select the data.

I am attempting to find some code to use in VB.NET to decrypt a string that has been encrypted using the Java crypto libary.All of the code I have found so far uses an Initialisation Vector and Key to decrypt but the string has been encrypted using the Key only. (Using an Initialisation Vector is apperently an optional step in Java).Does anyone know of code that I can use (preferably in VB.NET but i could convert C#) to decrypt AES 128 Bit encoded string without an Initialisation Vector?

I have a VB.NET windows application in which I'm using Outlook's contacts as my address book to get a list of email addresses. I'd like it to use Outlook as the address book, but if an Outlook mailbox has not been set up or there are no contacts then I don't want Outlook to come up at all. The problem that I'm having is as soon as I try to access Outlook the Outlook Startup Wizard comes up, which I don't want to happen. Here is my code:
Dim ao As Outlook.Application
Dim ons As Outlook.NameSpace
Dim Contacts As Outlook.Items

I'm trying to detect which contacts are currently opened, the only way I could come up with that was to actually get the items in the windows taskbar then compare the items to the contact list on Msn. This way when Bob@hotmail.com is currently opened my application can show a listbox of all the current opened Msn contacts. Is there an easier way to view the current open contacts with MessengerAPI

from Windows Vista, user contacts are not stored in .wab files anymore...However, they are stored here:
X:UsersYour User NameContacts
I want to CREATE / GENERATE contacts programatically and save them here in the same format.This format is very simple and is user readable.For example, this sample:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<c:contact c:Version="1" xmlns:c="http://schemas.microsoft.com/Contact" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:MSP2P="http://schemas.microsoft.com/Contact/Extended/MSP2P">
[code]....
However, although the final file contents will be exactly in the same format, but Windows will not recognize my created files as contacts!This is strange, I am sure they are in the same format!

I'm making a program for me and my partner to keep track of our contacts via a DataGridView. The thing is, I'm really confused by Databases. I was wondering if anyone can recommend a database or a solution to do this. I want it to be really simple, MySql is a little too much for what I'm doing, I'm just storing a custom class called "Contacts" into a DataGridView. The "Contacts" class has 3 properties at the moment.Name, Phone, Email. The database also needs to be online so my partner can access it. MYSQL might be the only option, I'm not sure

I created a vb.net application that reads a data file (SQL table) and creates contacts and groups from this data. If I run this application and point the Contact folder to my local Outlook folders, the application runs fine. It creates about 550 contact and 10 groups. My problem is when I go to run the application against a public folder that am the "owner" of with full permissions it will run fine until it hits items 250 and then I get a COM error.

I have a for loop going through customers and for each customer a update a list of contacts. If there is an error updating the contacts I want it to move on to the next customer and if there is an error in the customer update I want it to move on to the next customer. At the moment if I get an error it bombs out of the routine. Here is a simple example:-
For iRows = 0 to oledscustomers.tables(0).rows.count - 1
For iContactRows = 0 to oledscontacts.tables(0).rows.count - 1
'make some changes in here.
Next
Update Contact Table
'Make changes to customer tables and save them.
Next
If I get errors in the contact for loop or the customer loop it comes out of the routine altogether. I just want it to either continue to the next contact or customer.
