.NET Forum / Windows Forms / WinForm General / January 2008How to preload forms
In my application I use an mdi form in which I display several forms, What is the best way to preload this forms ? during the load event I goto the database to fill my comboxes.... thx for your quick response!  SignatureBest regards Luc What do you mean by 'preloading'? Do you want to create/instantiate whole forms in background, or do you just need to create some structures and fetch some data?

What I want to do is, fill the comboboxes with values and fetch some data. If I do this on form load, or in the constructor, the form becomes too sluggish... Is the only alternative to fire a background thread to do the fetching, and then invoke the forms thread to fill the combos?? > Is the only alternative to fire a background thread to do the > fetching, and then invoke the forms thread to fill the combos?? I believe so, yes.

Also dont invoke, just fill the combo from the other thread. I know I am cheating.. ... Else there is actually no difference if you use invoke, cause it is finally going to be executed on the same thread... Free MagazinesGet these publications absolutely FREE for up to 12 months.
