Try using the SetForegroundWindow() and ShowWindow() methods The import for them are

[DllImport("User32.dll")]
internal static extern IntPtr SetForegroundWindow(IntPtr hWnd);

[DllImport("user32.dll")]
internal static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

Declare an an constant called ActiveResize (or whatever name you want. like this. internal const int ActiveResize = 3; More size codes here.

Then generate an Activated event that will look something like this

private void YOURPROGRAM_Activated(object sender, EventArgs e)
{
    Process currentProcess = Process.GetCurrentProcess();
    IntPtr hWnd = currentProcess.MainWindowHandle;
    if (hWnd != User32.InvalidHandleValue)
    {
        User32.SetForegroundWindow(hWnd);
        User32.ShowWindow(hWnd, ActiveResize);
    }
}

What this does is when you the form is made active in any way the form gets an activated message. When it gets the message this code is then run which forces the window to be set to the foreground. Hope this helps.
