How To Decrypt Data From SQL Server
Dec 15, 2011Im having a problem in my coding. I am doing a username and password application (sumtthing like a password keeper).
So I have created the interface and i integrated vb 2008 with sql server 2008. So the adding of account and password all went fine.
I have applied aes 128 bits for the password. that means when the user enters a new record for example an email and he click save, the password will automatically be encrypted before it is saved in the database.
now im having a problem where when i want to display the password in the gridview of vb.net (i decided to use grid view to show all the username and password), i am having trouble in decrypting the password column to show the real password to the user.
of course user cant decrypt the password using their brains. so I want to know how to choose dat particular column (password column) and decrypt it before it appears in the gridview.
bcoz now it is appearing gibberish i.e. aes 128 bits. Below i show u some snippet of my codes in encrypting and storing it in the database. [code....]

Data Logging Application That Stores Data In A Table In A MySQL Database?
Dec 18, 2010I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?

Getting Data From MySQL Database And Editing It?
Sep 27, 2010 well this may be a simple question to some but for me, im not even sure where to start. I have never done a program in VB.NET yet that uses a MySQL database. So this should be a fun thing to learn. I looked at an example for access databases and it seemed pretty straight forward. But I must use MySQL as the database is on a Linux server in Ohio.
What I got so far is how to connect to the database using ADODB. Here the example I'm giving. You got 4 col's call AccountNum (primary key), Phone, Name, and Address. For each row is data of a client. What I'm trying to do: the program asks for the account number. You type in the account number of the client. It then
compares it to the rows of AccountNum col till it finds a row with it. Then it asks if you'd like to change the phone number or address.
So what I'm looking for is the, how to call rows and change data in col's.
Inserting Data Into A MySQL Table Using .NET?
Feb 10, 2012I have a problem inserting data into a table on a MySQL database using a VB.NET application. I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.
