I am using the built in functionality to define a splash screen using vb.net in VS2008. In Me.Startup, I'm calling a function which does a DB version check, then updates if required. This function then writes to a label, using an invoke if required to write the status. Everything functions fine, all the DB updates complete, but the spla...
