Hello!
if you like linux or mac os, you should also like the windows dragging cool trick right?
In linux you can drag windows anywhere by pressing ALT+CLICK… I’m not sure, but it should be the same thing in OS X.
Googling around… I found an interesting article in howtogeek.com that explains how to do that in Windows OS!!
The original script is here:
http://www.autohotkey.com/docs/scripts/EasyWindowDrag.htm
And this is the
howtogeek.com revisited script:

Oh, you want the complete package?
Ok ok… click here, extract it and put it in Autorun of your Winz.
If you want to write and compile you personalized version, I have coded a C# version, easy to use!
First of all, include Win32API in your code. This library is needed to send events to external windows.

static extern IntPtr SendMessage( int hWnd, uint Msg, int wParam, int lParam );
[DllImportAttribute( "user32.dll", CharSet = CharSet.Auto, SetLastError = false )]
public static extern bool ReleaseCapture();
[DllImport( "user32.dll" )]
static extern int GetForegroundWindow(); |
After that, set a timer and call GetForegroundWindow() just like this:
1
| int handle = GetForegroundWindow(); |
Now, create the KeyHook listener class:

Ok. Now, run it on Form_Load():

| KeyLoggerListener keylogger = new KeyLoggerListener();
keylogger.OnKeyPress += new KeyLogger.KeyLoggerListener.KeyPressHandler( keylogger_OnKeyPress );
keylogger.Run(); |

case Keys.Alt:
ReleaseCapture();
SendMessage( handle, 0xa1, 0x2, 0 );
break;
default:
break;
}

It’s all!
When the ALT key is detected, the program will launch a SendMessage( handle, 0xa1, 0×2, 0 ) passing the control (handle) of the foreground window and… you can move it!
Oh, by the way, you can also move an opened Windows’ Start Menu!
You don’t believe me? Watch this!!!
happy summer.
