}

but, when i want to run this project and i click the button that makes a call to this last function, i get a: Project Project3.exe encountered unhandled exception class Borland.Data.Common.BdpException with message 'Execute failed. unassigned code'.

So i can't make this thing work when i click the button1 showed before...

Please help...
