I have an application to re-sequence some items based on a an alphabetical ordering of the items from another table. I couldn't create an update statement to update the database when I pulled the information by a join query, So I pulled down both tables into a dataset with an XML Schema description where the two are related by the itm_id key as in the database. I then have two datagrids one with the items and one with the bound to the relationship this allows only the records associated with the itm to be displayed in the datagrid, I then run a loop that changes to sequence number for each corresponding record,this all works fine but then I go to update the back end database.
The update from the dataadapter executes successfully, but then if I reload the dataset from the database back end I find that the update did not actually update the records on the back end. The only record that was updated was the very first record which updated with a 0 then all the others did not take, I have re-run it several times and they will not take.
Me.Cursor = cursors.WaitCursor
odbaCatItem.MissingSchemaAction = MissingSchemaAction.AddWithKey
odbaCatItem.SelectCommand = odbsCatItem

Attempting to execute an update command against an Excel 2007 file gives the error:
Operation must use an updateable query. I'm using System.Data.OleDb with a connection string like this:
Dim strConn As String = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=""" & pathToFile & """;" & _
"Extended Properties=""Excel 12.0;HDR=YES"""
I have tried setting ReadOnly=false but that gives Could not find installable ISAM. I have also tried setting Mode=ReadWrite and IMEX=1 which didn't seem to have any effect. My update command is like this:
Dim cmd As OleDbCommand = con.CreateCommand()
cmd.CommandText = "UPDATE [" + sheetName + "] SET [Quantity Error] = 'test' WHERE [Full Name] = 'Mr. Brown White'"
where sheetName was obtained from querying the excel schema. Is it possible to do what I am trying to?

I have some excel file, where I have to programatically delete all hidden columns.The problem if that, when I receive these files, the cells are mainly formulas, and as I delete some columns I get some "#REF#" problems.
I thought a bit about the problem an decided to create a function that loops throught all cells and replace the value by its own value, before deleting the columns, via OLEDB:
dt.Rows(row)(col) = dt.Rows(row)(col).ToString I don't know if this works. So I followed an update example I found in google, but it doesn't work:
Dim conexao_Excel As String = "Provider=Microsoft.Jet.OleDb.4.0;data source=" & fileName & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1;"""
cn = New OleDbConnection(conexao_Excel)
cn.Open()
da = New OleDbDataAdapter("SELECT * FROM [" & sheetname & "]", cn)
da.Fill(dt)

I have login system where once logged in, there is a global variable which holds the users ID. In another form, I have an SQL update which updates rows in the user table. So my dilemma is this: When I try to update it either updates the first user only, or all users.
The SQL I have :
Dim Update As String = _
"Update User Set field1=?, field2=? field3=?"
What I would like is...
Dim Update As String = _
"Update User Set field1=?, field2=? field3=? where ID =?"
However this doesn't work.

Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.

I've been using Visual FoxPro for the past 10 years, and am trying to learn VB.NET, (using VS 2008). I am in the process of re-writing a small VFP app in VB.NET, and am using the VFP DBF tables, (via OleDb). It is a real struggle for me to comprehend all the levels to keep track of and was wondering in anyone knows of some sample code that would point me in the right direction. After I complete this small app re-write, I have others to do that all require the VFP DBF table updates.
