For some reason I seem to be unable to update my DB through the datasource. Is there anything obvious as to why this wouldn't be working?
I even added static values to the update string to see if this works but it still has an issue.
I have 4 file uploader in my form to upload 4 images in the DB for each article submitted. My issue when I want update/edit my article with some new pictures and I want delete or update the old pictures with the replacement with the new one.
How I can implement it? I am using ASP.NET based on VB.NOT .... NOT C#
How can i use update progress(in asp.net) with percentage (may be with remaining time span or remaining under process records) while data access from database but that should not be fixed for a fix time period by using like Thread.Sleep(5000). It should show for the actual accessing time period.

i have the code to test:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =8", Con)
Now, I need something like this:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" + LblInfoEditar.text, Con)
The problem:
The LblInfoEditar is outside the datalist so it works fine. (note: in this label I put a value like the 8)
But I have this label to test because I need to access a label inside datalist:
<asp:Label Visible="false" runat="server" ID="LblNumEntrevista" Text='<%# Container.DataItem("EntrevistadoCodigo") %>'></asp:Label>
The problem is: in this line I've to put something to access this LblNumEntrevista HOW?
I try:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" +
ListaPendentes.LblInfoEditar.text, Con)
But of course I don't work because I can't do this...

View 12 RepliesI am putting together a small database for recording stock movement.I have a table which will hold
StockID
StockItem
QtyInStrock
I want the user to enter in a textbox the number required from stock then do the subtraction before updating the QtyInStockWhat is the best approach for doing this.
I've been out of the ASP.Net arena since 1.1, and I'm starting to get back into it after a hiatus.
In the past, I would generally create SqlDataReaders, wire them up to pull from tables in a database via direct sql or accessing database views (mostly in MSSQL), grab the data, and display it in some datatable, or datalist.
Modifying data would usually be calling a stored procedure in the database to add/modify data, and then retrieve it afterward.
Now that I read up, I see there are alot of new things in ADO.Net world; strongly typed datasets, auto-generated adapters, etc.
My question is, does anyone have a good reference on best practices (or a book recommendation) on how to handle data access, and data manipulation and display now? I'm assuming that there are more automatic ways to show and manipulate data than before, but the new details are quite vast (which is good), but slightly overwhelming for me.
In Edit mode, when I check unchecked items, the Update works correctly, but when I clear the checked items, the items are still true in the database. My textboxes and dropdown lists all work as expected. The related code is below. Why won't the cleared checkboxes write to the db? When I set a breakpoint in the ContactRecordOnUpdating method, the values for the unchecked checkboxes are true (which is undoubtedly why they are written to the db that way).

I'm writing an update statement to update a user's password in the linked Access Database when they input (and confirm the input) of the new password in a textbox on my webpage.
The SQL statement that is being generated is - UPDATE tblUser SET [Password]=[chuck68] WHERE UserID=0000009
With tblUser being the correct name for the table, Password being the correct name for the field I wish to change and UserID being the linked field to lookup the password from.
The entirety of my code is as follows: (with the necessary import statement at the top of the class).
Protected Sub ChangePasswordButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ChangePasswordButton.Click
i am trying to update my database via a textbox on my web page.

Currently I run 2 separate queries to update + retrieve a tickent number. What happens if there're 2 users clicking on the same button at the same time? Could somehow two updates being run first and then both users get back the same ticket number?
string mySql = "UPDATE TicketCounter SET TicketNumber = (TicketNumber + 1)";
OleDbConnection myConnection = new OleDbConnection(accessConnStr);
OleDbCommand myCmd = new OleDbCommand(mySql, myConnection);
myCmd.Connection.Open();
myCmd.ExecuteNonQuery();
mySql = "SELECT TicketNumber FROM TicketCounter"
myCmd.CommandText = mySql;
OleDbDataReader myReader = myCmd.ExecuteReader();
