How to start new browser window in cpecified location whith cpecified size

Question

Hi all! I create a new instance and trying to resize new instance of browser like this:

[System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern bool GetWindowInfo(IntPtr hwnd, ref tagWINDOWINFO pwi);

    [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
    public struct tagRECT
    {
        /// LONG->int
        public int left;

        /// LONG->int
        public int top;

        /// LONG->int
        public int right;

        /// LONG->int
        public int bottom;
    }

    [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
    public struct tagWINDOWINFO
    {
        /// DWORD->unsigned int
        public uint cbSize;

        /// RECT->tagRECT
        public tagRECT rcWindow;

        /// RECT->tagRECT
        public tagRECT rcClient;

        /// DWORD->unsigned int
        public uint dwStyle;

        /// DWORD->unsigned int
        public uint dwExStyle;

        /// DWORD->unsigned int
        public uint dwWindowStatus;

        /// UINT->unsigned int
        public uint cxWindowBorders;

        /// UINT->unsigned int
        public uint cyWindowBorders;

        /// ATOM->WORD->unsigned short
        public ushort atomWindowType;

        /// WORD->unsigned short
        public ushort wCreatorVersion;
    }


    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern bool UpdateWindow(IntPtr hWnd);



    private void button2_Click(object sender, EventArgs e)
    {

        using (System.Diagnostics.Process browserProc = new System.Diagnostics.Process())
        {
            browserProc.StartInfo.FileName = webBrowser1.Url.ToString();
            browserProc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized;
            int i= browserProc.Id;
            tagWINDOWINFO info = new tagWINDOWINFO();
            info.cbSize = (uint)System.Runtime.InteropServices.Marshal.SizeOf(info);

            browserProc.Start();

            GetWindowInfo(browserProc.MainWindowHandle, ref info);

            browserProc.WaitForInputIdle();
            string str = browserProc.MainWindowTitle;
            MoveWindow(browserProc.MainWindowHandle, 100, 100, 100, 100, true);
            UpdateWindow(browserProc.MainWindowHandle);

        }
    }

But I get an "No process is associated with this object". Could anyone help? Or mb other ideas how to run new browser window whith specified size and location?

Oh, I fiend a solution! But, it works (in my system, at least) only whith IE...

We need to wait, until the Windows associate a window with process. Like this:

while (browserProc.MainWindowHandle == IntPtr.Zero)//пока винда не ассоциировала окно с процессом
            {
                Thread.Sleep(50);// ждём 50 мс
                browserProc.Refresh();// обновялем процесс
            }

And then we can obtain MainWindowHandle.
