I've been working on a script for to learn a few things (and to save some gnashing of teeth when Firebox blows up).
I used this little function to bring a Firefox window to the front: http://community.idera.com/powershell/powertips/b/tips/posts/bringing-window-in-the-foreground I had it working for a couple of hours, but somehow I broke it, and I can't figure out how I did that. Anyone have any ideas on what I glitched? Here's the script as it stands: ----------begin script---------- function Show-Process($Process, [Switch]$Maximize) { $sig = ' [DllImport("user32.dll")] public static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow); [DllImport("user32.dll")] public static extern int SetForegroundWindow(IntPtr hwnd); ' if ($Maximize) { $Mode = 3 } else { $Mode = 4 } $type = Add-Type -MemberDefinition $sig -Name WindowAPI -PassThru $hwnd = $process.MainWindowHandle $null = $type::ShowWindowAsync($hwnd, $Mode) $null = $type::SetForegroundWindow($hwnd) } # We're going to bring the lowest PID process with this name to the front $Firefox = get-process -Name firefox | sort Id # Let's see what we've harvested $Firefox # Bring the process to the front - give it focus Show-Process -Process $Firefox[0].id ---------end script--------- Here's the output, which contains a set of errors I can't decipher, as today my search-fu is weak. ---------begin output---------- PS C:\batchfiles> function Show-Process($Process, [Switch]$Maximize) >> { >> $sig = ' >> [DllImport("user32.dll")] public static extern bool >> ShowWindowAsync(IntPtr hWnd, int nCmdShow); >> [DllImport("user32.dll")] public static extern int >> SetForegroundWindow(IntPtr hwnd); >> ' >> >> if ($Maximize) { $Mode = 3 } else { $Mode = 4 } >> $type = Add-Type -MemberDefinition $sig -Name WindowAPI -PassThru >> $hwnd = $process.MainWindowHandle >> $null = $type::ShowWindowAsync($hwnd, $Mode) >> $null = $type::SetForegroundWindow($hwnd) >> } >> PS C:\batchfiles> # We're going to bring this process to the front PS C:\batchfiles> $Firefox = get-process -Name firefox | sort Id PS C:\batchfiles> PS C:\batchfiles> # Let's see what we've harvested PS C:\batchfiles> $Firefox Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id SI ProcessName ------- ------ ----- ----- ----- ------ -- -- ----------- 208 26 40604 58772 438 4.17 1480 1 firefox 502 84 334348 333860 993 88.53 4236 1 firefox 735 116 320392 376668 1036 41.20 5008 1 firefox PS C:\batchfiles> PS C:\batchfiles> # Bring the process to the front - give it focus PS C:\batchfiles> Show-Process -Process $Firefox[0].id Cannot convert argument "hWnd", with value: "", for "ShowWindowAsync" to type "System.IntPtr": "Cannot convert null to type "System.IntPtr"."
