Response Time Challenge


Recommended Posts

This website clocks response time. I myself average around at about 250ms. But who cares about a human's response time?
I present a challenge to you to make an application that takes the test. You can use any language you want. Post the **average** response times below!

http://www.humanbenchmark.com/tests/reactiontime

**Rankings**

1. Slasheree with 33ms average in VB.net
2. GalacticGlum with 34ms average in C#
3. Marsh with 47ms average in C++
4. Matt with 60ms average in C#
5. Matt with 60ms average in Python

My submission with a C# application.

Yeah, I just tried writing a lil 2 minute app and I got hung up on conditional expressions and operators.. I've forgotten so much.. Lol. Took me at least 5 minutes to write something as simple as

if (bool != true)
bool = !bool;

Absolutely ridiculous. =/

Source if anyone wants it

```
#include int main()
{
COLORREF green = 7002955;
COLORREF lastColor = 0;

while (true)
{
POINT p;
if (GetCursorPos(&p))
{
HDC dc = GetDC(NULL);
COLORREF color = GetPixel(dc, p.x, p.y);

if (color == green && lastColor != color)
{
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
}

lastColor = color;
ReleaseDC(NULL, dc);
}
}

return 0;
}
