Update Command - Errors On The Da.Update Line
Jun 12, 2011Here's my code
Dim suppQuery As String = "SELECT [Supplier ID],[Company],[Last Name],[First Name],[Email Address],[Mobile Phone],[Office Phone],[Address],[City],[ZIP/Postal Code],[Notes] FROM [Suppliers]"
Dim dsSupp As New DataSet
Dim daSupp As New OleDbDataAdapter(suppQuery, cnPharma)
[CODE]...
It errors on the da.Update line and by the way if it helps, the text fields are a product of datarowview. that is when you select an item on the listbox the details of that appears on the text fields. and my goal is i could edit those text fields and save them.

Update A Database Row With The Update Command?
Feb 11, 2010is there a way to update a database row with the update command by first defining all parameters and then all values just like you can in the insert command? "insert into table1 (parameter1,parameter2,....) values (value1, value2,....)"something like "set table1 (parameter1, parameter2) values (value1,value 2,...) where ...."?because I only know the syntax to define each parameters value "set table parameter1=value, parameter2=value2... where"

Update Records In SQL Server Database?
Sep 28, 2010I am using Visual Studio 2008 for creating a Winforms app. I have connected a database to it called XStats. There is one table in it called XGames and in that table 2 fields, XIndex (the primary key field) and GameNumber. Using the following code I can add records to the database, the data is taken from a text box, but once added I cannot view them unless I shut down the app and restart it.
con.ConnectionString = connectionString
con.Open()
Dim cmd As New SqlCommand

List To Update Every Time And Show The Values Each Time To Which The Previous Value Is Added To The New Calculation?
Jun 22, 2010The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:

.net - UPDATE Command With NULL?
Apr 27, 2011I am trying to update a column in my database with the date selected from a control on my ASP.NET web page. I need to ensure that the code is correct because nothing is updating in the column.
Code:
Command = New SqlCommand("UPDATE Parking SET ParkingStartDate = @StartDate1 WHERE Parking_ID = @radio)", myConn)
Command.Parameters.Add("@StartDate1", SqlDbType.Date).Value = StartDate.SelectedDate
Command.Parameters.Add("@radio", SqlDbType.VarChar).Value = radio
Command.ExecuteNonQuery()
myConn.Close()
if the column is already NULL, is it correct to use the update statement?

.Net CommandBuilder Will Update, Insert, But Not Delete Records In SQL DB?
Feb 15, 2012I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.

DGV Update - Allow Users To Edit Existing Records?
Aug 17, 2009I have a DataGridView bound to a non-SQL Server database. I need to allow users to edit existing records but under certain circumstances I need to intercept the edit and instead of committing and updating the dataset I need to delete the edited record and re-add it as a new record. I have tried using every event I can think of to do this but haven't managed to get it right.
The closest I have got is with this:
Dim theRow As DataGridViewRow
Private loading As Boolean = True
Private rowLeft As Boolean = False
Private WithEvents cm As CurrencyManager
Dim copiedRow0 As String
[Code] .....
This almost works but sometimes completely messes up and re-adds rows twice and all kinds of other bad side effects. It seems a really simple thing to want to do but I just can't get it working.
How To Update Records On An Existing Access Database
Sep 28, 2009how to update records on an existing access database using vb.net with just a textbox and a command button and how a specific record of a field can show up in a label or a textbox
i connected vb.net to my access database by just clicking on "add new data source">>"new connection">>"microsoft access database file" and just continue..tested connection and done.
you can see in the screenshot of my form, by default the left side textboxes are disabled but they're enabled if the user checks the checkboxes and disabled again if unchecked.
assuming that the textbox is already enabled and i want to enter a value in the Brewed Coffee area of the form...for example 5. when i click on my Submit button the value of that particular record in the database will be updated, so in my table the value of the quantity field in Brewed Coffee will be 5.
another thing is that how can i see a particular value on a label or textbox from my database like on the Prices area. in my database if a product's price is 80 then it should show a 80 in the label. the values of the prices from the screesnshot of the form are not the ones on the database xD i just typed them in.
