Here is an image of my table data and design I am trying to read some values from a database using the oledb dataset however when I run the sql command and get down to outputting the value I am greeted with the following error: "IndexOutOfRangeException: There is no row at position 0.". Yet when I run the very same sql command in access I get back the data I wanted.When I am running the above code, no errors are produced until I get down to the last writeline where I want to output my data.
I'm developing application in VB.NET 2008.I'm reading data from Excel through OledbConnection. Here data are reading sometimes perfectly but sometimes it is missing to read some data.
Example :In Excel ,I have 79 columns in excel and 4 rows , first 3 rows are headers so after import i'll delete that rows and actual data starts from 4, so here i have only one row.After Reading through oledb, that dataset's datatable has only first 3 rows( first row became header and 2 & 3 row only in datatable, its ignoring 4th row)

I have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

I am using oledbconnection object with access database engine 64 bit to get data from Excel file. While using sqlconnection object if sql string has these statements "SET ARITHABORT OFF;SET ANSI_WARNINGS OFF;" , then division by zero exception doesn't cause any problem. But while using oledbconnection these statements cause error. My code samples are below:
Dim PbpConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=C:BuzBeatDataPBPData.xls" & ";" & _
[Code]....
When SUM(pbA) has value "0" then it causes error and can't get data. is there a way to close the warnings and division by zero exceptions?
I'm converting a VB6 + ADODB app to VB.NET 2010 and targeting both x86 and x64 I understand that ADO is available in both 32 and 64 bits and that .NET supports it.The VB6 code uses ADODB and ADOX to work with OleDb and Odbc data sources. It also uses the Jet and Replication Objects 2.6 library to compact and copy Access database files (if the uderlying database it's using is Access)I'm wondering if I should consider using OleDbConnection/OdbcConnection in the .NET version of the software or stick with ADO.I've looked at OleDbConnection, OdbcConnection and SqlConnection and can see that porting the old code over would be time consuming and risky.

View 9 RepliesIn my application, I open a "Customer Details" form and on confirming I have to delete all records from other 2 tables (Order & OrderDetails) of the database. I am not able to delete records. It somehow stops by on - ordDetAdap.Update(ordDetDs) . The code is as follows :
[Code]...
There may be N number of Orders and each order may have N number of OrderRedetails. There are rows and also shows proper data in MsgBox, also row.Delete works fine, BUT why does it stop at Update(OrdDetDs) I can't make out. Any idea where am I going wrong.
Also Is their any easy way out to delete all records using just a single statement providing OrderId from OrderDetails table ? As of there are 10 rows of a single order, then For loop will iterate 10 times and delete 10 rows, instead if I can delete all 10 rows at once would be beneficial.
