I've been messing around trying to get an INSERT statement to work, and because of this, it has created lots of records in my database that I dont need or want.
The problem is, when I open up the table by right clicking on it in the database explorer and selecting "Show table data", I click on the record I want to delete and the following error comes up in a message box[code]...
I am having some issues with an application written in VB.net.
As part of a routine, an sqlce database gets backed up before the routine then if an error occurred gets restored. I am using system.io methods copy and delete.
I have released all the objects (connections, commands, datareaders) asscociated with the sqlce database by disposing them if they are not nothing. I also do a GC.COLLECT however when my delete command runs, an error message says it is open by another process. The PROCEXP.exe process explorer tool says it is attached to 4 undefined processes. After a while in debug mode, these clear and I am able to delete the file. However this is not acceptable as my program cannot "wait around" until they are released! I was under the impression that object.dispose forced an immediate disposal rather than waiting for the garbage collector to clean up (if you were just to use object=nothing), but still there appears to be a finite time before these objects are released.
My question is, is there an alternative way of checking (programatically in vb) for what is holding open an sqlce database (or in fact any other file for that matter) then killing these processes?

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.
