发送鼠标单击进行处理

Question

I'm trying to accomplish sending a mouse click to a application.

I currently have:

    int hWnd = FindWindow(null, "Window Title Here");
            SendMessage(hwnd, 0x201, 0, 0); //Mouse left down
            SendMessage(hwnd, 0x202, 0, 0); //Mouse left up

I'm using

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

and

    [DllImportAttribute("User32.dll")]
    private static extern int FindWindow(String ClassName, String WindowName);

But I get errors, these are:

"The name 'hwnd' does not exist in the current context"

How can I resolve this?

Answer 1

C# is case-sensitive. hwnd and hWnd are different things.

Answer 2

There's already libraries doing that, Windows Input Simulator would be an example, if you can use it, it would save you from having to write this kind of code. See on CodePlex
