public const int MOUSEEVENTF_LEFTDOWN = 0x02;
public const int MOUSEEVENTF_LEFTUP = 0x04;
public const int MOUSEEVENTF_RIGHTDOWN = 0x08;
public const int MOUSEEVENTF_RIGHTUP = 0x10;

public void MouseClick()
{
int x = 100;
int y = 100;

Hi, I'm using the following user32 functions: - SetCursorPos() to move the mouse - SendInput() to give a MOUSEEVENTF_LEFTDOWN and MOUSEEVENTF_LEFTUP IIRC the x,y parameters of mouse_event describe a relative mouse movement, so I keep them at zero. Here are my P/Invoke prototypes:

\[DllImport("user32.dll", CallingConvention=CallingConvention.StdCall, SetLastError=true)\]
public static extern IntPtr SendInput(int count, ref INPUT2 input, int size);

\[DllImport("user32.dll", CallingConvention = CallingConvention.StdCall, SetLastError = true)\]
public static extern IntPtr SetCursorPos(int x, int y);

public struct MOUSEINPUT {
	public int dx;
	public int dy;
	public int mouseData;
	public int dwFlags;
	public int time;
	public IntPtr dwExtraInfo;
}

public struct INPUT2 {
	public uint type1;
	public MOUSEINPUT mi1;
	public uint type2;
	public MOUSEINPUT mi2;
}

I only read code that is properly indented, and rendered in a non-proportional font; hint: use PRE tags in forum messages

And how exactly did you solve the problem? I'm interested because I'm working on same thing. Lukas
