How to tell when all a form and all it's elements are done loading
I thought about doing something like this, but I kinda thought of it as a
hack. What about if on some systems the images load very fast but some of
the other controls don't?
I think that what I might do is on the form load event, start a timer which
will check every few ms if everything is loaded, if everything is loaded,
then I will show the form (I will leave it's visibility off by default).
That should be pretty full proof no matter what, and I can do a splash
screen before I enable the timer.
In the timer tick event, which checks if everything is loaded, I would have
a series of nested ifs, and everytime it gets passed an if (the control IS
loaded), it will increment the splash screen load indicator bar (but it it's
already been incremented for that if(from a previous tick), then it won't
increment again).
I am still thinking about how to go about it.
