I have a design question about parsing data in Silverlight. I need to allow my users to validate their csv data (they paste ten rows into a textblock), but I am not sure if I should attempt to do it on the client side where I don't have access to the textfileparser class or send the data to a webservice for validation. If I send it to a webservice how do I ensure the data is secure?

How can I ensure that a user enters data in one text box before being allowed to move on to the next text box Example I have four text boxes the user can enter a grade in. I want to lock the other three box until the user has entered a number in text box 1. Once a valid number has been entered in text box 1, that releases or enables text box 2. Once a valid number has been entered in text box 2, that releases or enables text box 3. And once a valid number is entered in text box 3, that releases or enables text box 4.
View 5 RepliesPlease take a look at the code below. I was told by the individual that developed itoriginally that the code only adds the rows of data the user entered. In other words,there 5 rows of textboxes. user can enter data into one row or into all 5 rows. If the user enters data into one row of textbox, that's what gets inserted into the db.I made some minor change to the code so that users can tell when a payment is made by check or cash payment.Since I made that change, whether a user enters data into one row or all 5 rows, all 5 rows get inserted into the db.How can I modify this code to ensure only rows entered get inserted?

Amend the application:rate of pay to be entered as a real number;Employees are taxed at emergency rate of 40%. Amend to display GrossPay and NetPay.
2.Ensure that the operator cannot accidentally enter data in output areas!!!
The application is to be amended so thet the employees are paid overtime at time and a half for working more than 8 hours in any one session and all data enter by user should be checked to ensure that it is in a valid format and that the values are acceptable. [code]
I'm developing a VB.Net and SQL Server 2005 Express application.Q: How to encrypt string values in the database to secure them from the one using my software and from DBAs (people who have access to the DB Server)? Here is what I tried:First, I used a Symmetric Encryption provided by the .Net Framework. But I noticed that I could not make partial searches (LIKE keyword). So, this is not working.
Then, I used a logic similar to the ROT13 to hide text. Although this logic works fine from VB.Net, once data has been stored in the database, the logic fails to decrypt data correctly. After some tries, I thought that the reason the logic failed was the Collation of the database (I do not know much about Collation topic).So, the first way doesn't allow partial searches, and the second way is not secure and also does not work because of the Collation or maybe another reason.I want to encrypt data. I've successfully hidden the schema by giving meaningless names to tables and columns.
I am interested in making a simple budget program that retrieves current transactions from my bank account and categorizes them appropriately. Is the proper way to do this:
1)Automatically log into the website
2)Read and parse the data
3)Place in correct category?
Is there anything special I would need to do when handling the login/password or should I just do this manually?I'm assuming that is how popular prgrams like Quicken do it.
What would be the best way of storing data securely away from users. What I have is a stack of files that get downloaded by the program, at the moment they COME encrypted, and stored in a temp location. Now where would be the be place to store them, and how would I store them? The program reads normal unencrypted files but in order for me to open them at the moment I nee to decrypt them in the temp folder and open them from there.This is bad because anyone could find the temp folder and simply copy out all the unencrypted files.Opening the files and then decrypting the bytearray is out of the question because the program only takes a filename as a option.
View 2 RepliesI'm just starting to really get into JSON as a tool for my sites. I was showing my friend how I am calling a WS and returning the data, and he asked me about security of passing JSON data to and from a web service as he saw the data from the "POST" (via Firebug). Many of our public facing sites deal with member information and contain PHI.
Can I encrypt the JSON data and then unencrypt it? Is that a good way to go about it to ensure a layer of protection? Or is there another "better/right" way of doing it? Or are his concerns unfounded? how to encrypt or secure the JSON data when needed? Just trying to gather as much knowledge as possible before I go down a path that won't work for the company.

In silverlight, can you bind to a property that contains parameter? For example, the following doesnt seem to work. Am I missing something or is this not possible?

I have a number of very useful extension methods that I'd like to use in my Silverlight project.I've pasted the Module here [URL]The problem I'm having is that visual studio complains that the dlls my module have been written against have not been built against the Silverlight runtime.Is there an easy way to get these extension methods working in Silverlight?I'm thinking my main hurdle is getting IObjectSet and ObjectContext to run against the Silverlight run-time - perhaps there's another way to expose these methods that I'm not aware of.
View 1 RepliesI have a SQL stored procedure that I bind to a Silverlight Datagrid. That works ok, the problem is when I use the same stored procedure to bind a different dataset to the same grid, it doesn't display the new data, only empty columns from the last dataset that was bound. What is going on here? I tried to set the grid = Nothing and I tried using Datagrid1.columns.clear() but that didn't work.

I have created a nested loop and want to write the value of a variable into a record in the database table. Typically I have seen that textboxes, etc are connected to the database. How do I update the details for one record as part of the VB function?
Details are (excuse the pseudocode):
For loop (y axis)
For loop (x axis)
Within these storing values x,y,R,G,B,Y,U,V,mask as integer

I was wondering if anyone knew of a good tutorial for parsing data from a text file and then populating the data into multiple text boxes. I have a text file with information pertaining to my form. The text file consists of key identifiers for each piece of information needed and I was wondering how to programmatically fill in my form by parsing that data.

I am using VB.NET and I am designing a generic network architecture in which data can be transmitted in various ways. I am wanting to strip down things as much as possible, and I do not want to transmit in plain text. My question today is regarding ideas and example code (if applicable) as far as parsing binary data that is sent over the wire in VB.NET.I want each packet to have a very generic architecture such as <packet type> <address> <payload> or whatnot. I understand that I can use certain bytes as delimiters for these packet fields. I don't necessarily want to serialize everything being that for security reasons, the same library has to be used to deserialize the data.
a) Put my protocol into binary data where each field is delimited using a certain byte
b) Parse that data from binary at the other end.
Once again, I don't want to use plaintext since this can cause a bunch of overhead in comparison.

is it possible to communicate with a bluetooth device? I have a fairly simple heart rate monitor which has a USB stick, which connects wirelessly to the monitor.

I am trying to parse incoming data from a serial port that appears to be XML format but a few problems arise when going from a simulated setup to the real deal. I first made a this program at home using a serial port emulator and com port connector program that reads from a text file and then sends it through the com port, I then read it from the com port it is connected to it. My program is able to parse the incoming XML perfectly fine, I'm using an XML Literals syntax.
The problem I run into is when I setup my program with the device and try and parse the data that is coming out of it. The data I receive sometimes has a few lines of garble before it starts seeing my expected XML. Of course these few lines of garbled text throws me an exception, but even when it appears I'm getting a good clean start of my XML data my program still throws exceptions such as "unexpected end of line 1 line number (different lines)" or "multiple root elements line 1".
Am I going about this the right way? using XML Literals to process my XML string properly or should I use something else that will allow for not well formed XML? or am I just missing something. My device outputs data every 500ms and I can poll my device for stored data. An example of what I am receiving sometimes and what I am expecting is below. "The first few lines of text sometimes appear and sometimes don't" [Code]

View 5 RepliesLet me preface this by saying I'm VERY limited in my programming knowledge/experience using any language. I mean I have extremely basic capabilities and don't quite understand this stuff inside and out like most of you do.Anyway, I'm trying to code a fantasy football draft program in VB 2010 that utilizes the MS Internet Transfer Control 6.0. It will retrieve the HTML from a website, say ESPN, and parse the data into player names, rankings, and other stats. Should all be simple strings/sub-strings. It will then populate a DataGridView control so that each row in the DGV has the player's name, ranking, projections for the season, etc. After this has been populated, the program will be designed to allow me to draft players and assign them to the various teams automatically. I am the commissioner and we do an off-line draft, so I will just make picks for everyone and submit them online later.
