Question

Is there a way to position a form just above the clicked Notify Icon in windows 7 and windows Vista?

Answer 1

Regarding your comment: “how could i know how is the taskbar positioned?”

Check out the following article which contains a class which exposes a method for retrieving a Rectangle Structure for the tray: [c#] NotifyIcon – Detect MouseOut

Using this class you can retrieve the Rectangle Structure for the tray like so:

Rectangle trayRectangle = WinAPI.GetTrayRectangle();

Which will provide you with the Top, Left, Right and Bottom coordinates for the tray along with its width and height.

I have included the class below:

using System;
using System.Runtime.InteropServices;
using System.Drawing;
using System.ComponentModel;

public class WinAPI
{
    public struct RECT
    {
        public int left;
        public int top;
        public int right;
        public int bottom;

        public override string ToString()
        {
            return "(" + left + ", " + top + ") --> (" + right + ", " + bottom + ")";
        }
    }

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern IntPtr FindWindow(string strClassName, string strWindowName);

    [DllImport("user32.dll", SetLastError = true)]
    public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, IntPtr windowTitle);

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool GetWindowRect(IntPtr hWnd, out RECT lpRect);


    public static IntPtr GetTrayHandle()
    {
        IntPtr taskBarHandle = WinAPI.FindWindow("Shell_TrayWnd", null);
        if (!taskBarHandle.Equals(IntPtr.Zero))
        {
            return WinAPI.FindWindowEx(taskBarHandle, IntPtr.Zero, "TrayNotifyWnd", IntPtr.Zero);
        }
        return IntPtr.Zero;
    }

    public static Rectangle GetTrayRectangle()
    {
        WinAPI.RECT rect;
        WinAPI.GetWindowRect(WinAPI.GetTrayHandle(), out rect);
        return new Rectangle(new Point(rect.left, rect.top), new Size((rect.right - rect.left) + 1, (rect.bottom - rect.top) + 1));
    }
}

Hope this helps.
