Directing mouse events [DllImport("user32.dll")] click, double click
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, UIntPtr dwExtraInfo);
private const uint MOUSEEVENTF_LEFTDOWN = 0x02;
private const uint MOUSEEVENTF_LEFTUP = 0x04;
private const uint MOUSEEVENTF_RIGHTDOWN = 0x08;
private const uint MOUSEEVENTF_RIGHTUP = 0x10;
You should Import and Define these Constant's to work with Mouse using Win32API
Use method's below to do Mouse Operation's
void sendMouseRightclick(Point p)
{
mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, p.X, p.Y, 0, 0);
}
void sendMouseDoubleClick(Point p)
{
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, p.X, p.Y, 0, 0);
Thread.Sleep(150);
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, p.X, p.Y, 0, 0);
}
void sendMouseRightDoubleClick(Point p)
{
mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, p.X, p.Y, 0, 0);
Thread.Sleep(150);
mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, p.X, p.Y, 0, 0);
}
void sendMouseDown()
{
mouse_event(MOUSEEVENTF_LEFTDOWN, 50, 50, 0, 0);
}
void sendMouseUp()
{
mouse_event(MOUSEEVENTF_LEFTUP, 50, 50, 0, 0);
}
If you want to do a Mouse Drag you should First Send MouseDown(Mouse Click) and keep it Clicked While Changing the Mouse Position than Send MouseUp(Release Click) something like this .
sendMouseDown();
Cursor.Position = new Point(30,30);
sendMouseUp();
Using long type raises an "PInvoke" error.
We should use int type:
[DllImport("user32.dll")]
static extern void mouse_event(int dwFlags, int dx, int dy,
int dwData, int dwExtraInfo);
[Flags]
public enum MouseEventFlags
{
LEFTDOWN = 0x00000002,
LEFTUP = 0x00000004,
MIDDLEDOWN = 0x00000020,
MIDDLEUP = 0x00000040,
MOVE = 0x00000001,
ABSOLUTE = 0x00008000,
RIGHTDOWN = 0x00000008,
RIGHTUP = 0x00000010
}
public static void LeftClick(int x, int y)
{
Cursor.Position = new System.Drawing.Point(x, y);
mouse_event((int)(MouseEventFlags.LEFTDOWN), 0, 0, 0, 0);
mouse_event((int)(MouseEventFlags.LEFTUP), 0, 0, 0, 0);
}
