Maximized IE windows launch from PowerShell

[Balazs Torocsik]

Since I did not find the correct solution anywhere, including the below VBScript thread (which is closed), I would like to to share my solution to this problem in PowerShell.

thread329-1364653

#We will use the Win32 API function ShowWindowAsync, and spawn an IE Window Maximized.
#Parameters can be used for ShowWindowAsync
$Hide = 0
$Normal = 1
$Minimized = 2
$Maximized = 3
$ShowNoActivateRecentPosition = 4
$Show = 5
$MinimizeActivateNext = 6
$MinimizeNoActivate = 7
$ShowNoActivate = 8
$Restore = 9
$ShowDefault = 10
$ForceMinimize = 11


#Specify an interwebs address :)
$URL="[URL unfurl="true"]http://www.google.com/"[/URL]
#Create internetexplorer.application object
$IE=new-object -com internetexplorer.application
#Set some parameters for the internetexplorer.application object
$IE.TheaterMode = $False
$IE.AddressBar = $True
$IE.StatusBar = $False
$IE.MenuBar = $True
$IE.FullScreen = $False
$IE.visible = $True
#Navigate to the URL
$IE.navigate2($URL)

#the C#-style signature of an API function
$code = '[DllImport("user32.dll")] public static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);'

#add signature as new type to PowerShell (for this session)
$type = Add-Type -MemberDefinition $code -Name myAPI -PassThru

#get the window handle
$hwnd =(Get-Process -Name "iexplore").MainWindowHandle
$hwnd

#Magic  -- in my case, $hwnd is an array with 2 IDs, but only 1 integer can be used as IntPtr for ShowWindowAsync, so I am taking the later one.
if($hwnd[0].ToInt32() -gt $hwnd[1].ToInt32()){
    $type::ShowWindowAsync($hwnd[0], $Maximized)
}else{
    $type::ShowWindowAsync($hwnd[1], $Maximized)
}
