How to i insert Variable @ClassID(If Identity Propeties) @LecturerID , @StudentID and a Date from Calendar Control into the Date Collumn , into a Database Called Fingerprint, TableName= Attendance.
The Collumn Are ClassID, LecturerID, StudentID, Date.
I've been staring at this and can't seem to come up with a solution. I've tried several different methods that i found on the web but to no avail. I'm hoping you all could take a look at the code below and give me some direction as to why I'm receiving the error "The INSERT INTO statement contains the following unknown field name: 'Deposit_Date' . Make sure you have typed the name correctly and try the operation again. Sorry if it's kinda jumbled below
Code:
Dim SQL As String = "INSERT INTO Deposits ( Deposit_Date, Deposit_Time, Location, Miscellaneous, " & _
"Miscellaneous_Adjustment, Dispense, Dispense_Adjustment, " & _
"Replacement_Card, Replacement_Card_Adjustment, Deposit, " & _

Thought I should probably say im using Windows 7 and the 2010 beta Visual studio
I have been following a tutorial in a book Vb 2005 Jumpstart Ch 4..Anyway I have followed the books code exactly and the program runs.It connects to Amazons web service and allows the user to search and display books, the application also allows the user to save the titles that they wish by clicking an Add Title button, when the user does this the current focus title is saved to the database and can be viewed off line.When I hit the add title the record gets saved as I can hit the catalog button which opens a new form with a datagrid that has all the titles I just saved in it!! But when I close the app and run it again the catalog is gone?? back to no records again?Now ive never worked with SQL databases before and this is me just having a go at .Net so I have no idea whats wrong or where to look.[code]

I have an access database with 3 tables, want to collect data from 2 and insert them into a new row in the third (although this seems redundant there are reasons for wanting it that way). I created a form and call the data from the two tables fine, once the form is filled I try to add a new row to the third but it will not add the row even though it is telling me that is has. When I open my access table the record is not there. I am new at this and just can't figure out why it won't work, I have tried several approaches the latest is

Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

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?
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.

View 5 RepliesI have an Access database with a table called Events.I created a new VB.net 2008 project and created a MicrosoftReportViewer control. I also added a "Report" component (which created a .rdlc file).I am easily able to drag things from my Access database I added to the data sources onto the report. However, one part of the report I would like to add data to a Matrix that I calculated with VB (ie it is not in the database). The database has a list of names and a bunch of times associated with each name. and then I calculate some fancy stuff based on those times. I would like the matrix to be a list of names (from the database) on the rows, a list of dates (which I specify in the code) on the columns, and the data of the matrix I also calculate.

Ive got a web page so that the users select a day from the calendar and the date is input to a text box, the format is dd/mm/yyyy, it is the same format in the database table.
I want to select the data from the database when it is = the date in the text box but it is retrieving data in mm/dd/yyyy format. My sql is:
SELECT Booking.Date, Booking.RoomNo, Booking.Lesson, [NoComps] - " & students & " AS diff FROM Rooms INNER JOIN Booking ON Rooms.RoomNo = Booking.RoomNo WHERE booking.Date= #" & txtdate.Text & "# AND booking.Lesson = '" & lessonlist.SelectedValue & "' AND booking.Type IS NULL
how can i make sure it retrieves the data using the correct date format?

View 1 RepliesI was wondering which way would be the easiest in VS2005 to connect to and pull data from a MS SQL database. I have already setup the database connection by choosing the datasource for a DataGridView but I'm not able to retreive any information.
The steps I have taken so far:
1. Make new form
2. Drag and drop DataGridView onto the form
3. Setup the data source and respective username password
Not sure where to go from here....

View 4 RepliesI need to extract specific data from a database. With starting point in this data, I will collect information on the internet. After the information is collected I need to check if this information is already stored in the database, and if not, then add it. This action is being repeated about 500-50000 times each time the procedure is being executed. (not often)
The approach I'm taking seemes sleazy and ineffecient and I was hoping you could point out some places where I might be able to optimize it. I've two open connections at the same time. The first I use to extract data, and it stays open throughout the whole session. The second connection is being used first to check if an entry already exist and if not, to add the data.
The reason I am using two connections is due to the fact that I got a reader bound to the first one, so it is rendered unavailable.
I was thinking that maybe checking if the data existed, and adding it if not, maybe could be contracted into one command execution instead of two. I don't know if it would be possible to do this with one connection only as well, as it seemes more proper.
