嗯,首先,我想要做的是单击一个 Flash 对象内的一个特定点,在一个 webbrowser 控件内。我不确定它为什么不起作用,但我似乎无法单击任何窗口,无论是记事本还是实际程序。
这是我正在使用的代码。
[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, IntPtr windowTitle);
[DllImport("user32.dll")]
public static extern IntPtr FindWindow(String sClassName, String sAppName);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
[DllImport("user32.dll", SetLastError = true)]
static extern bool PostMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);
public IntPtr find()
{
return this.Handle;//FindWindow("", "Form1");
}
public enum WMessages : int
{
WM_LBUTTONDOWN = 0x201, //Left mousebutton down
WM_LBUTTONUP = 0x202, //Left mousebutton up
WM_LBUTTONDBLCLK = 0x203, //Left mousebutton doubleclick
WM_RBUTTONDOWN = 0x204, //Right mousebutton down
WM_RBUTTONUP = 0x205, //Right mousebutton up
WM_RBUTTONDBLCLK = 0x206, //Right mousebutton do
}
private int MAKELPARAM(int p, int p_2)
{
return ((p_2 << 16) | (p & 0xFFFF));
}
/** This is the non-working code **/
public void DoMouseLeftClick(IntPtr handle, Point x)
{
SendMessage(handle, (int)WMessages.WM_LBUTTONDOWN, 0, MAKELPARAM(x.X, x.Y));
SendMessage(handle, (int)WMessages.WM_LBUTTONUP, 0, MAKELPARAM(x.X, x.Y));
return;
//I have tried PostMessage, and SendMessage, and both of them at the same time, and neither works.
PostMessage(handle, (uint)WMessages.WM_LBUTTONDOWN, 0, MAKELPARAM(x.X, x.Y));
PostMessage(handle, (uint)WMessages.WM_LBUTTONUP, 0, MAKELPARAM(x.X, x.Y));
}
private void timer2_Tick(object sender, EventArgs e)
{
//I try hovering my mouse over a button I added to the form, and nothing happens.
DoMouseLeftClick(find(), Cursor.Position);
}
所以,我尝试过使用 PostMessage 和 SendMessage,但它们似乎都不起作用。我需要做的就是点击一个特定的点。
另外,我需要提到我不能使用mouse_event,因为据我所知,窗口需要处于活动状态,而且光标需要在您单击的点上方。我正在制作一个自动在 Flash 对象中执行进程的机器人,所以这就是我不能使用 mouse_event 的原因。
谢谢你们的帮助。
