C# WebBrowser send Mouse Click Event to Flash Object

问题

I've been reading around but didn't seem to find an answer to this question. The objective is: I have a WebBrowser in a Windows Forms Project. There is a HTML page loaded, and in that HTML page there is a Flash Object. My goal is to send a Mouse Click to (x, y) positions of that Flash Object.

The (desired) Requisites

The window with the Windows Forms executable doesn't need to be active in order for this to work
The mouse must not be captured
Send a mouse click based on coordinates (x, y), relative to the Flash Object or the Web Page

Example

Imagine I open any Tower Defense game in the WebBrowser. I want to simulate clicks to buy and place new towers. During the proccess the user must not loose control of the mouse. If at pixel (x, y) = (30, 50) was a button and I wanted to click that button, I could just by calling something like WebBrowser.simulateLeftClick(30, 50).

回答1:

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr GetWindow(IntPtr hWnd, uint uCmd);

[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern int GetClassName(IntPtr hWnd, StringBuilder lpClassName, int nMaxCount);

Class can be defined by means of Spy++

public static void MouseClick(int x, int y, IntPtr handle, string Class)
{
    StringBuilder className = new StringBuilder(100);
    while (className.ToString() != Class)
    {
        handle = GetWindow(handle, 5);
        GetClassName(handle, className, className.Capacity);
    }

    IntPtr lParam = (IntPtr)((y << 16) | x);
    IntPtr wParam = IntPtr.Zero;
    const uint downCode = 0x201;
    const uint upCode = 0x202;
    SendMessage(handle, downCode, wParam, lParam);
    SendMessage(handle, upCode, wParam, lParam);
}

WebBrowser handle

IntPtr handle = webBrowser1.Handle
