just would like to ask if it is possible to manually populate the datagrid in asp.net 2003 using vb.netwe usually populate the datagrid using this code, in this code what it does is it populate the datagrid base on your query , it's automated you can't edit or evaluate the data inside.
dataGrid.DataSource = ds
dataGrid.DataBind()
What if if I want to edit or evaluate the data inside the DataSet?

I have a form and some controls as dropdown and textboxes..
The situation is that when the form loads, i want the value in textbox to be incremented, everytime it loads..
This is something i tried.. I get the value '1' everytime !! It shows no sign of increment..
However, i also want it in the format 0001,0002 if possible..I tried something like this..
Private Sub Order_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
textBox1.ReadOnly = True

I have constructed my database and I have used auto increment the ID's of each column. When I was testing and inserting data into my tables the auto increment of these column's of course incremented.
Now I am looking to start each individual Id column at 1 and not at the number where it is now.
I know it has something to do with using max value and +1. I have deleted the entire table and have tried everything to re-insert my data and start the ID's at 1, but I have had no luck.
Also to,
I know within Vb I can use a datagrid view and add there and it starts at the max value of the column +1, but when I have another form to add data within columns the column number is not in numerical order, How do include code within that seperate form to auto increment ID column numerically?

i have a datagridview which have 3 columns, two button columns increase or decrease, 3rd displays the value increased or decreased from button. i have datagridview_CellContentClik behind button columns. The problem is increase in value on pressing button is very slow. i mean if i press button quickly the value should increase quickly but its the same slow pace for increasing or decreasing value on pressing button.

I'm new to the world of VB.Net <-> Databases.I'm currently working on an application with SQL Compact 3.5.I realize that data et values on objects from the database but what I want is more custom...Students should have 3 fields for example, tableId, their name and birthYear.1 | John | 20002 | Peter | 1999And so on. What I want is to display their birthday on some label.text = "(" & DBvalue & ")" based on the selection of a listbox (which has tableId's listed as values). You don't have to worry about the update method of that label.text value, I just want a way to retrieve the birthYear value and put it into my label.text together with those extra characters, based on the tableId selected. (which I already have a way to get, so don't worry about that either).

I have used My.Settings for quite some time now, in both VS2005 and now in 2008, but never noticed this behaviour yet... I must be forgetting something trivial? I create a StringCollection setting and manually enter some data (strings).I write some code to handle this, and I get it to work.
Then, I manually add some new strings (and edit the older ones) in the Settings page, save the project, and run my code again.For some reason, the last changes have not been saved... Whenever I look in the settings page, I see them there, but my code cannot recognize them..

I'm currently working on a project where I am transmitting data from a comm device via the serial port and resorting the raw data (in binary) to its respective ascii values. The problem I'm facing is determining the most efficient method to accomplish my goal. Essentially, I have 68 bytes coming in, the first and second bytes represent the page and packet number and the data itself ranges from 3 to 64, the remaining for my checksum.
What I am needing to do is, grab 50 consecutive bytes per variable in my array, and that is where I'm confused. I have easily pulled my 3-64 bytes and stored that data to a string. I just don't know the most efficient method to accomplish my goal. Should I write directly to file all my data, as there are like 8 pages, of 128 packet data. [Code] I can capture the the first 50 by using a for-loop easily, but what would be the preferred method to track what data chunk I've taken? The more I think about it, I think I may just want to write to file, all my data, and then just take them back to back in 50 byte chunks. Is that the most efficient method?

I have finally figured out how to download a file with background worker and downloader. Now the form does not freeze.. I have only one problem left now... How do I get the progress bar to increment in tandem with the data flow? I have listed my full code below. Towards the bottom where the DoWork() sub resides, I am just a few lines short of this year long goal.

I have a Visual Basic 2008 Windows form application that processes some scores and data. I want to export the data to an Access database. I have created the Access database and connected it to the VB program.I am looking for a simple set of commands or sample code to add records to the database. Perhaps I am oversimplifying the problem, but it seems like it should be so much easier than it has proven to be. I only want to export the data in code; the user should never see the database or do anything to it while the program is running.

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.
