In C/C++ LONG lStyle = GetWindowLong(hwnd, GWL_STYLE); lStyle &= ~(WS_CAPTION | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_SYSMENU); SetWindowLong(hwnd, GWL_STYLE, lStyle); WS_CAPTION is defined as (WS_BORDER | WS_DLGFRAME). You can get away with removing just these two styles, since the minimize maximize and sytem menu will disappear when the caption disappears, but it’s best to … Read more
x86 does not require alignment for a lock cmpxchg instruction to be atomic. However, alignment is necessary for good performance.

Anyways the code bellow let you access the [Audio]::Volume and [Audio]::Mute properties from PowerShell. This also work on … Read more

The EnumSerialPorts v1.20 suggested by Nick D uses nine different methods to list the serial ports! We’re certainly not short on choice, though the results seem to vary. To save others the trouble, I’ll list them here and indicate their success in finding the com0com ports on my PC (XP Pro SP2): CreateFile(“COM” + 1->255) … Read more
There is a simple way to do it in powershell (at least) : $o = new-object -com shell.application $o.Namespace(‘c:\My Folder’).Self.InvokeVerb(“pintohome”) Hope it helps.
Colorization color != the base color chosen. It’s misleading, I know. But I’m confused. The image you borrowed was from my post entitled “Retrieving Aero Glass base color for opaque surface rendering”. Is this not what you want to do? I also indicated in the post the registry location in which all the color information … Read more
