When I discussed some time ago why minimized windows have an apparent size of 160x31, I explained that the minimized icon is a miniature title bar, but I managed not to explain why the values are exactly 160 and 31. The width of the miniature title bar is determined by the What about the height? That's just the height of a caption bar, which you can adjust from the Appearance tab of the Display control panel. (Programmatically, you can use that helpful |

But that doesn’t tell us why THOSE values were chosen. Why not 162×34? Inquiring minds want to know!
So is 160×31 like some kind of cool prime number or something?
I have to ask – is it DorkMaster or DarkMaster?
Graphic designers!?
Since when did graphic designers work on Windows??
I thought the monstrosity called "Luna" was definitive proof that no graphic designer had any input whatsoever…
Most people like Luna.
Because everything that needed to fit fits.
I pity The fool that thinks its DorkMaster. I like dark primes.
@ Dorkmaster
160 x 31 = some kinda cool prime???
Really. Back to 5th grade math for you!
Google will tell you why you are silly.
Granted, setting the MinWidth registry value directly may be "wrong", but it is a documented "wrong". Also, it’s the only way to do it non-programmatically — not everybody knows how to write a program that calls an API function, after all. Plus, the iWidth member of MINIMIZEDMETRICS is expressed in pixels; MinWidth is expressed in [negative] twips, which are not only device-independent but are also an order of magnitude more precise.
I mentioned in the earlier thread that the width of a minimized window is determined not just by the minimized-window width value (i.e., iWidth) but also by the window border width. At 96 DPI, the default minimized-window width value is equivalent to only 154 pixels, not 160. The extra six pixels are accounted for by the left and right window borders.
Similarly, the default minimized-window height of 31 pixels is arrived at by adding iCaptionHeight to the top and bottom window borders.
I would like to know what the significance of the number "1033" is. For years (decades, even?), folders with this name show up in many MSFT apps, including Office and Visual Studio. I’ve asked various high-ranking MSFT people, and to a one they shake their head. But it must be formalized somewhere, because it keeps showing up. Inside joke?
RBL: use the search box to the right and type in 1033 and you’ll find that oldnewthing already answered your question :)
I believe 1033 is the decimal representation of 0x0409, which is the LCID for "English (United States)".
There are other common LCIDs as well that you can see around, and I think MSDN might actually have a list of them somewhere.
The [b]actual[/b] window is given magical, negative constants to place it off-screen when minimized.
CreateWindow* does not check the X and Y values on the creation of a window, meaning that a lack of input validation [i]will[/i] place the window off-screen.
Before you start thinking that there *should* be input validation on window coordinates, Raymond II, consider that virtual window managers rely on being able to have windows off-screen when not visible. Also it would be tricky to figure out when a window would be off-screen on configurations with multiple monitors that are of different sizes.
Gabe, look up Multiple Display Monitors on how to get the monitor associated with a virtual-screen coordinate, and have the window fall back to the primary display monitor in case it’s outside of any monitor, ensuring that the window shows up somewhere it can be seen rather than nowhere.
