Vb net tableadapter update not updating database Where can i sex chat with real woman yahoo answers
And sure enough, when you go to Server Explorer and browse to the rows that should have been changed in the first run you can see that the data is unchanged.
That's because, when you press F5, Visual Studio quietly copies your database from your project's root folder to the bin/Debug folder, and that's the version of the database that your code updates.
When you think about it, this is a good idea: Individual test runs leave your test data unchanged.
But if you want one test run to build on the changes from a previous test run…well, you're out of luck.
Hello, i have a Gridview which is bind with a table adapter to a database.
On this form i have a button for deleting records and it works very well.
First decide what database table you want to do this for. To this end, we've added a custom property to My Sql Command Builder called Return Generated Identifiers. Write Line("Pass#1 before update : row.id=" ", Row State=" row. Row State); Table Test Data Set.tabletest Row row2 = dt. Write Line("Pass#2 before update : row2.id=" row2", Row State=" row2. If you checked Return Generated Identifiers a bug appear, if Return Generated Identifiers is true, Updated Row Source must be set to none... Everything should be handled automatically with as little code as possible.Probably everyone in the world but me knows how Visual Studio handles database files during testing in a GUI-based project. NET projects, I didn't clue into this behavior until recently.But even if you do know about this "feature," you may not be aware of how you can improve on Visual Studio's default behavior.
