I suspect that the event that is created is not an OS event , but rather local to the running application.

HANDLE h = CreateEvent(NULL, FALSE, FALSE, "TestEvent");
WaitForSingleObject(h, 5000);
cout << "past event";

[DllImport("kernel32.dll")]
static extern bool SetEvent(IntPtr hEvent);

[DllImport("Kernel32.dll", SetLastError=true)]
static extern IntPtr OpenEvent(uint dwDesiredAccess, bool bInheritHandle, string lpName);

IntPtr handle = OpenEvent(0x000F0000 | 0x00100000 | 0x3, false, "TestEvent"); // First parameter is EVENT_ALL_ACCESS
SetEvent(handle);

I want to use LineTo(), but each time do I have to store the previous mouse point into a global variable as the starting point for lineto().
