screenshotmachine-vb

This demo shows how to call online screenshot machine API using Visual Basic programming language.

Installation

First, you need to create a free/premium account at www.screenshotmachine.com website. After registration, you will see your customer key in your user profile. Also secret phrase is maintained here. Please, use secret phrase always, when your API calls are called from publicly available websites.

Set-up your customer key and secret phrase (if needed) in the script:

    Dim customerKey As String = "PUT_YOUR_CUSTOMER_KEY_HERE"
    Dim secretPhrase As String = "" REM leave secret phrase empty, If Not needed

Website screenshot API

Set additional options to fulfill your needs:

    Dim options As New Dictionary(Of String, String)
    REM mandatory parameter
    options.Add("url", "https://www.google.com")
    REM  all next parameters are optional, see our website screenshot API guide for more details
    options.Add("dimension", "1366x768") REM Or "1366xfull" For full length screenshot
    options.Add("device", "desktop")
    options.Add("format", "png")
    options.Add("cacheLimit", "0")
    options.Add("delay", "200")
    options.Add("zoom", "100")

More info about options can be found in our Website screenshot API.

Sample code

Imports System.Net

Public Class Client

    Public Shared Sub Main(args() As String)
        Dim customerKey As String = "PUT_YOUR_CUSTOMER_KEY_HERE"
        Dim secretPhrase As String = "" REM leave secret phrase empty, If Not needed

        Dim options As New Dictionary(Of String, String)
        REM mandatory parameter
        options.Add("url", "https://www.google.com")
        REM  all next parameters are optional, see our website screenshot API guide for more details
        options.Add("dimension", "1366x768") REM or "1366xfull" for full length screenshot
        options.Add("device", "desktop")
        options.Add("format", "png")
        options.Add("cacheLimit", "0")
        options.Add("delay", "200")
        options.Add("zoom", "100")

        Dim sm As ScreenshotMachine = New ScreenshotMachine(customerKey, secretPhrase)
        Dim apiUrl As String = sm.GenerateScreenshotApiUrl(options)
        REM use final apiUrl where needed
        Console.WriteLine(apiUrl)
    End Sub

End Class

Generated apiUrl link can be placed in <img> tag or used in your business logic later.

If you need to store captured screenshot as an image, just call:

    Dim apiUrl As String = sm.GenerateScreenshotApiUrl(options)

    REM or save screenshot directly
    Dim client As New WebClient()
    Dim output As String = "output.png"
    client.DownloadFile(apiUrl, output)
    Console.WriteLine("Screenshot saved as " + output)

Captured screenshot will be saved as output.png file in current directory.

Website to PDF API

Set the PDF options:

    Dim options As New Dictionary(Of String, String)
    REM mandatory parameter
    options.Add("url", "https://www.google.com")
    REM  all next parameters are optional, see our website to PDF API guide for more details
    options.Add("paper", "letter")
    options.Add("orientation", "portrait")
    options.Add("media", "print")
    options.Add("bg", "nobg")
    options.Add("delay", "2000")
    options.Add("scale", "50")

More info about options can be found in our Website to PDF API.

Sample code

Imports System.Net

Public Class ClientPdf

    Public Shared Sub Main(args() As String)
        Dim customerKey As String = "PUT_YOUR_CUSTOMER_KEY_HERE"
        Dim secretPhrase As String = "" REM leave secret phrase empty, If Not needed

        Dim options As New Dictionary(Of String, String)
        REM mandatory parameter
        options.Add("url", "https://www.google.com")
        REM  all next parameters are optional, see our website to PDF API guide for more details
        options.Add("paper", "letter")
        options.Add("orientation", "portrait")
        options.Add("media", "print")
        options.Add("bg", "nobg")
        options.Add("delay", "2000")
        options.Add("scale", "50")

        Dim sm As ScreenshotMachine = New ScreenshotMachine(customerKey, secretPhrase)
        Dim pdfApiUrl As String = sm.GeneratePdfApiUrl(options)

        REM save PDF file
        Dim client As New WebClient()
        Dim output As String = "output.pdf"
        client.DownloadFile(pdfApiUrl, output)
        Console.WriteLine("PDF saved as " + output)
    End Sub
