javascript - Powershell Scroll down a webpage / Powershell Screenshot

Question

How to open a webpage in powershell and scroll down.

Actually I am making a script which will do a network report on its own and give me a screenshot which I want. I can open the webpage and start the test with my script, but I want my script to scroll down so that the correct screenshot could be taken. Please Help.

To be precise, I want my script to open a website called testmy.net and do a network report. I want to take the screenshot of just the report and crop everything else. I would really appreciate any help.

Q) How do I scroll down a webpage in PS? I open the website and I want to scroll down?

Q) How do I take a screenshot of only a particular thing? (After some research I got some part which could take a screenshot of the whole desktop)

I have attached the screenshot of exact thing I need.

Script Starts Here:

$ie = new-object -comobject InternetExplorer.Application -property `
    @{navigate2="http://testmy.net/SmarTest/combinedAuto"; visible = $true}

# Wait for the page to finish loading

$ie.fullscreen = $true

do {sleep 5} until (-not ($ie.Busy))

# Take A ScreenShot (Script taken from Stackflow)
[Reflection.Assembly]::LoadWithPartialName("System.Drawing")
function screenshot([Drawing.Rectangle]$bounds, $path) {
$bmp = New-Object Drawing.Bitmap $bounds.width, $bounds.height
$graphics = [Drawing.Graphics]::FromImage($bmp)

$graphics.CopyFromScreen($bounds.Location, [Drawing.Point]::Empty, $bounds.size)

$bmp.Save($path)

$graphics.Dispose()
$bmp.Dispose()
}

$bounds = [Drawing.Rectangle]::FromLTRB(0, 0, 1000, 900)
screenshot $bounds "C:screenshot.png"

I think you're looking for really quick and dirty. If that's true, and you don't mind ugly, try using SendKeys.

$ie = new-object -comobject InternetExplorer.Application -property `
    @{navigate2="http://testmy.net/SmarTest/combinedAuto"; visible = $true}

# Wait for the page to finish loading

$ie.fullscreen = $true

do {sleep 5} until (-not ($ie.Busy))

[System.Windows.Forms.Cursor]::Position = New-Object system.drawing.point(700,700)
[System.Windows.Forms.SendKeys]::SendWait({DOWN 10})

# Take A ScreenShot (Script taken from Stackflow)
[Reflection.Assembly]::LoadWithPartialName("System.Drawing")
function screenshot([Drawing.Rectangle]$bounds, $path) {
    $bmp = New-Object Drawing.Bitmap $bounds.width, $bounds.height
    $graphics = [Drawing.Graphics]::FromImage($bmp)

    $graphics.CopyFromScreen($bounds.Location, [Drawing.Point]::Empty, $bounds.size)

    $bmp.Save($path)

    $graphics.Dispose()
    $bmp.Dispose()
}

$bounds = [Drawing.Rectangle]::FromLTRB(0, 0, 1000, 900)
screenshot $bounds "C:mpscreenshot.png"

Keep messing around with the number of down arrows you send until it's right -- so edit {DOWN 10}.

NOTE: Chirishman says that you need to have two squiggle brackets around DOWN 10 -- {{DOWN 10}}. The version above almost certainly worked verbatim on my box at the time of writing, but ymmv.

Scared you're going to have enough timing issues that you eventually go back and use another tool, however. How many of these do you have to take?

Note that I did change the URL to espn.com while testing. Not sure what's going on at yours -- a speed test? Seemed to load about three different pages.
