Parsing Data From A Loop To A SQL Record?
Feb 23, 2010
I'm using Visual Studio 2008 and am creating a Visual Basic application. This is connnected to a SQL server database - standard settings.
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 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?

I'm trying to loop over record set with While sqlResults.Read() But it seems that if i only have one record in the collection it will skip it and won't enter the loop, is there some kind of fix to this?

I am trying to loop through a dataset and process n numbers of records at a time.For example lets say I have around 240 records in my dataset. I need to loop through the dataset and then create a new batch of 50 records. so for the dataset which has 240 records I want to create 6 batches. Out of these 6 batches, 5 would have 50 records and and last batch would have 40 records.

Okay, if someone gets to my website using something like the following address:
ww.mywebsite.com?FirstName='John'?LastName='Smith'
Is there a way that I can pull out the FirstName and LastName and assign to them variables to be used later?
I've looking around but I'm not sure what it's called so I don't know how to search it.

As you all know, If the dataBase requires a numerical value then an error will occur when the user tries to insert the incorrect data type. With the code below after the user types in a value beside an int value type then it will go into an Loop through more than what is needed. How can I apply the same logic but allow the program not to check the 60 rows (I set the row size to 60). I want to break out of it if there are blanks ONLY if a row is blank and not for a black cell, because if the user leaves one cell blank then it would loop through the 'for each' for how many rows that they is. Initially there are 60 rows.
MIS
For Each item As DataGridViewRow In dgvLaser.Rows
If IsNumeric(item.Cells(3)) Then
Exit For
Else
MessageBox.Show("Check Record Count. Numerical values only..!")
End If
Next

I have created an auto emailer to distribute our work routes for my colleagues. Problem is I made it easy for the management team to update the list. List is ordered by Tech Number, First name, Last name, Email address.
I have coded this in VB.NET 2008 using Database sources and drag-n-drop the table on the form. I let VB do most of the coding of the connection and text boxes. (IE If (Tech_TextBox.Text <> "9999") Then)What I would like to do, instead of using a bogus tech number as an exit. I need an 'IF Then" or 'DO UNTIL' after last record.

I only need the two items in bold for each row, but these fields need to stay together and match up.I have the XML loaded as type XmlTextReader, but I'm not sure how to read through it and extract what I am wanting.

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 reading from an IO.port and returning the data to a string. I need to parse this to data rows that each represent a data record which I will add to a datagridview.
The data basically looks like this. I have inserted <SOH>,<US>, etc. for readability.

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

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.
It utilizes a serial port (COM3), where I can communicate with it. I've tried all sorts of data formats to parse the incoming bytes, from ASCII to INT32 to string... Nothing.

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]

Let 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.
