I'm helping someone convert a huge mess of panels and 700 meticulously-placed checkboxes with something slightly more sane. My plan is to implement a custom control that uses the ControlPaint class to draw the checkboxes manually; this will make it easier to work with the data and dropping 700 GDI handles from the form will likely be a ...
So I'm new to C# and have done a few gamey projects as learning exercises. One I'm currently doing is a sort of practice run at an RTS. It's VERY basic stuff. I have a commandbutton that builds tanks; said tanks are instances of a class that contains a picturebox. Said tanks can be moved around by left clicking anywhere on the form wh...

I'm building a control that comprises 15x15 = 225 buttons, and needs to be resizable. Because it's a grid, anchoring and docking won't work. I've tried both TableLayoutPanel as well as handling the resize event to manually place and size controls. In both cases, resizing is unacceptably slow. Suspend/Resume Layout in the resize funct...
I'm looking for an effective way to notify the user that a given form is currently loading (or updating) it's UI and it will take few seconds. This may occurs at initial load or at update.
