In a project with several forms, when some data in one form was changed it is necessary to update another form. Se when the first form closes, the form #2 makes visible and reads some data from a database. For couple of seconds the form window not fully repainted until all data was read. I think that I need to put the process of reading the data from a database into a separate thread, while the second form state changes to visible. So far I have never used threading, so I would appreciate any advice how to implement it.

Thanks
