Datagridview not updating Free sex chat rooms no sin up
Good afternoon, I've been searching all over the web for help with this but I'm not getting exactly what I want.I have an application that uses an access database. Its displaying the data just fine in the datagridview but when I make changes in the Data Grid View, its not saving.Since you call New later in the code, do not do it at the declaration. There are different ways to deal with that, but the simplest one would be to declare your da and dt variables at the form level, between Public Class Form1 and the first Sub.This creates a first Data Adapter that you never use and that needs to be destroyed when the second New Ole Db Data Adapter is encountered in the code. When I add the line "da.fillschema(da)" I get an error in my code (see screenshot) I did everything you said (I commented out the da.fillschema(da) line) but it sill wont update. That way you are using the same Data Adapter and the same Data Table everywhere.It includes both the history of SQL and its technical basics.
