How send Lwin shortcut key in vb.net

Question

Can someone tell mew how to send Shortcut keys in vb.net? The shortcut keys are {LEFTWIN} + {ADD} amd {LEFTWIN} + {SUBTRACT}. Tried SendKeys.Send it does not work.

Answer 1

Finally this worked for me :)

Private Declare Sub keybd_event Lib "user32.dll" (ByVal bVk As IntPtr, ByVal bScan As IntPtr, ByVal dwFlags As IntPtr, ByVal dwExtraInfo As IntPtr)
Private Const VK_STARTKEY = &H5B
Private Const VK_SUBTRACT = &H6D
Private Const VK_ADD = &H6B
Private Const VK_ESCAPE = &H1B
Private Const KEYEVENTF_KEYUP = &H2
Private Const KEYEVENTF_KEYDOWN = &H

Call keybd_event(VK_STARTKEY, 0, KEYEVENTF_KEYDOWN, 0)
Call keybd_event(VK_ADD, 0, KEYEVENTF_KEYDOWN, 0)
Call keybd_event(VK_ADD, 0, KEYEVENTF_KEYUP, 0)
Call keybd_event(VK_STARTKEY, 0, KEYEVENTF_KEYUP, 0)

EDIT The keybd_event is deprecated so I am moving to SendInput(). The first solution works best for me :-)
