[2.0] VB6 to C#

[Evan]

How does this if statement translate to C# (I dont get the And &H8000 )


Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal vKey As Long) As Integer


Private Sub Timer1_Timer()
Dim keystate(1) As Integer

keystate(0) = GetAsyncKeyState(vbKeyControl)
keystate(1) = GetAsyncKeyState(vbKeyTab)

If keystate(0) And keystate(1) And &H8000 Then
'If hotkey is pressed
End If
End Sub

using System.Runtime.InteropServices;
using System.Windows.Forms;

// ...

[DllImport("user32")] private static extern int GetAsyncKeyState(long vKey);

private void Timer1_Timer()
{
  int[] keystate = new int[2];

  keystate[0] = GetAsyncKeyState(Keys.Control);
  keystate[1] = GetAsyncKeyState(Keys.Tab);

  if (keystate[0] & keystate[1] & 0x8000) {
    // hotkey is pressed
  }
}

edit: you'll need to modify the signature of the tick event handler as appropriate.

Remember that VB6 numbers are half the width of .NET numbers, so it should be:

private static extern short GetAsyncKeyState(int vKey);

Ah, yes. I read VB.NET by mistake.

Change the array to shorts as well.
