Unable To Delete Record In Database
Mar 5, 2009
I am connected to a mdb using OleDb. The Connection code is :
' GET CONNECTED TO DB
Try' Open a connection to the database.cn = New OleDb.OleDbConnection(strConnection)cn.Open()
' Load Data Adapteradapter = New OleDb.OleDbDataAdapter(strSelect, strConnection)
' Create Auto generated Insert, Update, Delete cmds for Tableautogen = New OleDb.OleDbCommandBuilder(adapter)
[Code] .....
Add & Update are working perfectly, but delete doesn't update in the db. While application is running it shows that data is deleted, but when I run again, I see the same data, so its not physically deleting from the db. Add & Update both are working perfectly even after re-running.Can anyone tell me where am I going wrong in delete part. The row is also proeprly selected. No exceptions, yet why not deleting physically.

Dim sqlcheck As String = "SELECT SerialNumber FROM EquipmentDetail WHERE SerialNumber = '" & TextBox1.Text & "'"

Basically, I am making a booking system. On one of the forms, you can: Add, Edit and Delete a record by using the selected index. I can do the Add and Edit part fine but some problems are occuring when I try to delete it. What I'm trying to do when deleting is, copy all the records except the selected one and then copy it back into the original file again.

I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.
