Can I SIMULATE a MOUSE CLICK in a minimized window ? ?

private const int BM_CLICK = 0x00F5;
//Used by EnumChildWindows returns true if should continue
public delegate bool CallBack(IntPtr hwnd, IntPtr lParam);

//Enumerate the child controls until the callback returns false
[DllImport("User32.dll")]
public static extern bool EnumChildWindows(IntPtr hWndParent, CallBack lpEnumFunc, IntPtr lParam);

//Gets the text of the window at the passed pointer address
[DllImport("User32.dll")]
public static extern Int32 GetWindowText(IntPtr hWnd, StringBuilder s, int nMaxCount);

//Gets the classname of the window at the passed pointer address
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
static extern int GetClassName(IntPtr hWnd, StringBuilder lpClassName, int nMaxCount);

[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

[DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);

[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam)

IntPtr hwnd=IntPtr.Zero;

//Get a handle for the Calculator Application main window
hwnd = FindWindow(null, "FormToBeCaptured");
//Should check for empty hwnd (== IntPtr.Zero)
//Enumerate through Children until callback returns false
EnumChildWindows(hwnd, ButtonClickCallback, IntPtr.Zero);

//Get the text in the object at the pointer
private static string GetText(IntPtr hWnd)
{
    StringBuilder formDetails = new StringBuilder(256);
    GetWindowText(hWnd, formDetails, 256);
    return formDetails.ToString().Trim();
}

//Get the class name of the object at the pointer
private static string GetClassName(IntPtr hWnd)
{
    StringBuilder formDetails = new StringBuilder(256);
    GetClassName(hWnd, formDetails, 256);
    return formDetails.ToString().Trim();
}
        
// This method is called as a delegate each time a child is enumerated. 
// If it returns false, enumeration will stop.  
// The whole tree will be traversed without further code despite only
// passing the root.
public bool ButtonClickCallback(IntPtr hWnd, IntPtr lParam)
{
    string text = GetText(hWnd);
    string className = GetClassName(hWnd);

    //OK: These need to be class level feilds or something
    if (text == "Add" && className.StartsWith("WindowsForms10.BUTTON"))
    {
        //send BN_CLICKED message
        SendMessage(hWnd, BM_CLICK, IntPtr.Zero, IntPtr.Zero);
        return false;
    }
    return true;
}
