What I expected After installing Heroes of Might and Magic VI and then starting it through Steam, the game should enter the main menu. What I got The game screen is only black and never enters the main menu. How I solved it Go to My Documents > Heroes of Might and Magic VI. Open ProfileData with your favorite text editor Replace <gfx_Fullscreen2>Fullscreen</gfx_Fullscreen2> with <gfx_Fullscreen2>Windowed</gfx_Fullscreen2> Start game. Game will be in windowed mode, but it’s better than nothing ...

One problem which I encounter time and time again when creating a webpage or applications is matching text color with a changing background color. When creating a GUI you usually create a lot of white boxes with a black text on it, just to get sizes and stuff matching. Then later a designer or customer decides on a theme which affects how that box looks. Most of the time the background and text colors are hand-selected so they match well enough, but from time to time you have to create a box which can change background color on demand, and then you have to have the text color matching to make the box readable. I have done too many slightly different solutions to this problem, so I thought I would write something down here. Since most of the time, text colors are off-white and off-black, the formula should be tweakable to match any given hue. ...

I usually don’t have a keyboard key mapped to caps, since I have my caps mapped to escape instead. However, from time to time it still gets activated.
