What I want to happen is that the button from my system will remove the previous data from database and then insert new data to database from text file. Im done with inserting new data. The thing is that I dont how to control or where to put the Delete Command from my code.
[Code]...
I got a system which i want to insert, delete, update the data into my database and the data from database will be display using datagrid. The below is the coding for one of my button, delete.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Try
btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?
Try
Dim SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand
SQLconnect.ConnectionString = "Data Source=" & Application.StartupPath & "Databasedb" & ";"
SQLconnect.Open() ' VS highlights this line

Is it because of the database extension ? I used sqlite Admin to create tables
Edit : I just tried it out in VS 2008, it works flawlessly. Why is it not working in VS 2010. Does it something have to do with app.config file ? or .net framework 4 ?This is what I added in the app.config file
<?xml version="1.0"?>

I am looking for ways to retrieve data from textfile and save it into access database. Currently, I am doing a attendance record project. I need to save the attendance record which is given in a text file to the database. The version of VB i using is VB 2008.
The content of the text file look like this:
E010,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR
E022,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR

I tried to create a class and store the record but it just don't work.
I'd like to export a table from Access to a text file (or a spreadsheet) using VB code in Excel 02. I'm using the transfertext command but my code runs through without actually doing anything or throwing up any errors. If I swap the code round and change Export to Import and move the data into the text file manually then the code will happily import the table into Access.
Sub Export()
dbfile = "C:XLSMDBTable.mdb"
Dim a As Object
Set a = CreateObject("access.application")

when i try to insert data from database into dataset using data adapter, it takes long time, i want to use hourglass but i'm confused how or when i type the code so user will know that application still work.
View 1 RepliesHow do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:

I know of a long way that is to just create a createVendor1, createVendor2 as many time as i need to insert the data..but i don't think this is the right way to do it. this is what i have currently, if i remove the 2nd insert , it works. NOTE: There is a semi colon at the end of the insert but that is not the problem as removing it also doesn't work.
