Hi guys,

I'm having an issue when i'm trying to save the modification I make in my dbase. I'm using a save button, the first save work fine but if I modify my data and try to save again I get this message: concurrency violation the updatecommand affected 0 of the expected 1 records. I get this message at the tableadapter.udapte line. I'm using visual basic express 2010. Here's my codes for my save button:

Me.validate()
Me.donneesoiseauxbindingsource.endedit()
Me.donneesois_oiseauxtableadaptater.update(datatable)

Thanks for helping me
