I have created a file say "abcd.xml".I have created this in a device which can be connected to my system and synchronized(which means data from the device can be synched to the database and vice versa).Now when I reset the device all the details in the device is lost but it exist in the file. When we do a reset and do a sync I need to check a condition and if its true I need to load the details from the file to database.This is what I'm supposed to do
I am new to using databases in applications and i have a code to select data from the database. However, the first time the application starts, new data is inserted into the database which is needed after. But, the data does not appear until the whole application is restarted. How I can refresh the database content.
The current code for selecting the data is: Imports System.Data.SqlServerCe Public Class MSSUI Dim con As SqlCeConnection = New SqlCeConnection(My.Settings.DB1ConnectionString) Dim cmd As SqlCeCommand Dim myDA As New SqlCeDataAdapter [Code] .....
I have a GridView, named GridView1 used to getting data from SQL Server Database, because the data from database always changing, I would like to get the new data to display on the GridView1 when a user press the "Fresh Button"

GridView1.Refresh() - did not work Me.Refresh() - did not work Me.Hide() then Me.Show() did not work
I am trying to place a repeater within a repeater using xml data. I have it working exactly as I want, but the method I have used reloads the data for each repeater. I think I need to cast as an XmlNode but I'll be honest - I have no idea where to start. Here is my code - I'd like to keep everything in the code behind if possible.
when im updating my data through a textbox and i save it, i dont automatically show the updated file on the datagrid, here is my code btw, i already tried some code but it aint working
Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

I am sitting with a situation that I have to combined (3 years) for 26 site of 29000 database files where there is 1 table in each data base called RECDATA, I need to combined all that data Into one database file called RECDATA.
For example there is a database called DB1 with a REDATA table inside it, and then DB2 with a RECDATA table inside it, DB3 with a RECDATA table inside it est. So I need to put all the Recdata into 1 Database file, or to copy all the RECDATA from all the database files to 1 RECDATA they all have the same columns All I need is to get all that data into 1 RECDATA table.
The program where this database comes from is a voicerecording system creating a new database every day. There is 1 database just for indexing (to view the recordings) and then the daily database is where the recording lies in, that Colum is called RECFILE. I will give you a example of the 2 database.
I'm only getting started with VB.Net, using VB Express 2008.Using the System.Data.SQLite wrapper, I need to read data off a SQLite database file, and chart data using basic bars, pies, lines, etc. Nothing fancy.
I am creating a txt file which containing some data. I wish to create a form using vb.net with the browse button which browse my txt file into my sql server database. Can i know how can i do that?Besides, I can i insert picture as well using txt.file ? If not, can i know what is the alternative way ?
I'm using Microsoft.Jet.OLEDB.4.0 to set/get data from database access file, but it isn't working perfectly on 64-bit systems, so I'm looking for an alternative way.set/get data from database access file working on 64-bit systems.
I want, when I show Form2, the form1 should be displayed in background. And when I close Form2, the form1 should be updated or starting complete new Form1. I do this but there are two tabs of Form1 in TaskBar. One is background display Form1 and another is updated. I want only one Form to be displayed.
I've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead If intPlayerOneHealth <= 0 Then btnReplay.Visible = True End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything

I have added the following code to the datagridview rowleave event: [code]I'll figure out a way to skip the update if nothing is changed, but for right now, it doesn't work. I've searched MSDN, the MS Community forum and several other forums for a solution and all I have found is what I already have and it doesn't work.I can make changes at run-time alright, but the exception it triggered when I change rows, and the data is not saved to the database file.When I close/re-run the app, the changes to the data are not thereThere has to be a way to save changes to the datafile, but I'm just not finding it.

I use Visual Basic in Access, and I have no problem writing data directly to a cell in a database table. But I can not figure out how to write the code for Visual Basic 2008. For example I would use Me![cust_Cost] = 20 to input 20 in the database table. I have purchased two different Books on Visual Basic 2008 and not one of them show how to input data manually.
I have a gridview control on my asp.net page(vb.net). I also have a "cancel" button, that when pressed, is supposed to clear the gridview of it's current contents.
However whenever the cancel button is pressed, it just reloads the page and the gridview is still there with the same data that I wanted clear.[code]...
I have a listbox, a textbox, and a button. The button populates the textbox with the selected item & value of the listbox. As below:
Protected Sub GetVariables_Click(ByVal sender As Object, ByVal e As EventArgs) Handles GetVariables.Click Me.txtLetter.Text = lstNames.SelectedItem.ToString & lstNames.SelectedValue.ToString End Sub
The problem I have, is that when doing this it reloads the page each time. Any way around this?
