如何检测多个显示器及对其进行设置，以及如何在窗体中模拟鼠标点击

[hb1122]

电脑显卡有两个输出接口连接了显示器，桌面在其中的一个接口显示，另一个显示展示窗体界面，问题是，如何找到本机的显示器，以及如何把窗体显示到某个屏幕上去。
如何在窗体中模拟鼠标点击。

不胜感激!

可以买一个接口连接多显示器就可以了。

Screen.PrimaryScreen '主显示器
将界面显示到另一个显示器没试过,可能可以通过矩形区域来实现,如同鼠标拖窗口到另一屏幕思路.

模拟鼠标事件:
Private Declare Sub mouse_event Lib "user32" Alias "mouse_event" (ByVal dwFlags As Integer, ByVal dx As Integer, ByVal dy As Integer, ByVal cButtons As Integer, ByVal dwExtraInfo As Integer)

Const MOUSEEVENTF_RIGHTDOWN = &H1
Const MOUSEEVENTF_RIGHTUP = &H2
Const MOUSEEVENTF_LEFTDOWN = &H3
Const MOUSEEVENTF_LEFTUP = &H4

示例:

mouse_event(&H3, 0, 0, 0, IntPtr.Zero)
鼠标左键按下

[System.Runtime.InteropServices.DllImport( "user32.dll ")]
static extern bool SendMessage(IntPtr hWnd, Int32 msg, Int32 wParam, Int32 lParam);

private void SetNoCurrentCell()
{

SendMessage(Form2.Handle, WM_LBUTTONDOWN, 0, 0);
SendMessage(Form2.Handle, WM_LBUTTONUP, 0, 0);
}

Screen [] screens = Screen.AllScreens;
if( screens[0].Primary)
Console.WriteLine("screens[0] is Primary Screen!");

Console.writeline(screens[0].DeviceName);
还有些有用的属性和方法可查MSDN

Screen 类

Cursor.Position 属性

Cursor.Position = new Point(
    Screen.Bounds.Width / 2,
    Screen.Bounds.Height / 2);
