VB.net在应用程序启动时填充数据集

Question

I have a winforms application that has an sql server backend. I have some tables that have static data, lookup tables, that I would like to fill in my dataset at application start to be used throughout the application when needed.

Normally in a form I would use something like this: Me.TEMSWBSETableAdapter.Fill(Me.EMS_DS.TEMSWBSE)

But I would have to do that in every form that required that data. The problem is it takes awhile to load that data, so I would like to load the data at startup in a background worker that can be used by any form that requires it. Basically filling the dataset with that data for use throughout.

I am not sure how to do this. Can someone point me in the right direction. Thanks

you first need to implement DataReder object that can retrieve data with out creating a database TableAdapter. this will load your data with forward only and read only mode of the ADO.net mechanism.then you can implement ExecuteNonQuery() method to append the changes directly to the database.
