I want this to happen in a loop where there is no sleep; adding any sleep hurts performance as I basically want the events to go in to the event loop immediately once they have been generated. Of co...

A google search shows a few examples on how to download a file in Delphi but most are buggy and half of the time don't work in my experience.

I'm using the AnimateWindow API to show or hide a Form with a slide animation. The problem is that if the Form contains a RichTextBox control, it doesn't display this control correctly. It's transparent and doesn't show any text. After the animation is complete, double clicking somewhere in the control will reveal lines of text. I've c...
