Type a page name and press Enter. You'll jump to the page if it exists, or you can create it if it doesn't.
To create a page in a module other than user32, prefix the name with the module name and a period.
Changed the IntPtr lParam to string lParam to enable the possibility to use a string as input.
Sample Code:
// notify all windows that User Environment variables are changed
IntPtr HWND_BROADCAST = (IntPtr) 0xffff;
const UInt32 WM_SETTINGCHANGE = 0x001A;
UIntPtr result;
IntPtr settingResult = SendMessageTimeout(HWND_BROADCAST,
WM_SETTINGCHANGE,
(UIntPtr)0,
"Environment",
SendMessageTimeoutFlags.SMTO_NORMAL,
10000,
out result);

An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.
