WebASP ActiveX Control (HTTP and HTTPS)

Use the WebASP control to communicate with Web Servers using HTTP and HTTPS. The WebASP control differs from the PowerTCP Http control in the following ways:

It is WinInet independent, making this control suitable for high-performance web server applications
It uses an intuitive WebMessage object to represent HTTP Requests and Responses
It integrates with the WebPage object, providing powerful HTML parsing and resource collecting

Features include:

Easily Get a complete web page with one method call
Post files to the server using the PostedFile property
Use the WebPage object to gather HTML resources and to parse HTML
Cookie object makes it easy to create and send cookies within your code
Secure (HTTPS) connections fully supported
Customize certificate handling
Client authentication fully supported

Development Environments

Visual Basic (VB)
Visual C++ (VC++)
Delphi
ASP
MS Office
Visual Studio .NET (COM Interop)
more

Code Example

How easy is the WebASP control to use? Check out the following VB example below, which gets an HTML file and saves it to disk.

'Reset the Request Message
WebASP1.Request.Content = ""

'Get a file
WebASP1.Request.Url = "www.test.com/testweb.html"
WebASP1.Get

'Check the result
If WebASP1.Response .Status = 200 Then
    'Good response from server
    'Save it to a file
    WebASP1.Response.Body.Filename = "C:\temp\TestWeb.txt"
End If

Http ActiveX Control (HTTP and HTTPS)

The Http control is used to communicate (send GET and POST requests) with HTTP and HTTPS servers. Features include:

Full support for Secure connections
Easily Get a complete web page with one method call
Simulate form posts
Send cookies or custom headers
Post data and files

Development Environments

Visual Basic (VB)
Visual C++ (VC++)
Delphi
ASP
MS Office
Visual Studio .NET (COM Interop)

Code Example

How easy is the Web Control to use? Check out the following VB example, which gets an HTML file and displays its contents.

Dim Orderform As String
Http1.Timeout = 20000 'Give it 20 seconds to complete
Http1.Url = "http://www.dart.com/" 'Specify the URL to GET
Http1.Get Orderform 'Send a GET request, Orderform will be filled with data
Text1.Text = Orderform 'The HTML code for the web site appears in the text box

WebPage Object

The WebPage object is used to represent an HTML page for parsing and resource collecting. Features include:

Full integration with the WebASP control - get a page and parse it
Get all images, links, meta-content, or other HTML resource on a page
Parse locally saved HTML documents
Powerful HTML table parsing (such as grabbing the value of a cell)
Find content between two tokens

Development Environment

The WebPage object can be used in many development environments including:

Visual Basic (VB)
Visual C++ (VC++)
Delphi
ASP
MS Office
Visual Studio .NET (COM interop)

Code Example

How easy is the WebPage object to use? Check out the following VB example below, which demonstrates getting and saving all images on a web page.

'WebPage object to use for parsing
Dim WebPage1 As New WebPage
Dim blnResult As Boolean

'Set Request url
WebASP1.Request.Url = "www.dart.com"

'Get the page
WebASP1.Get

'Set webpage source to html source from Response
WebPage1.Source = WebASP1.Response.Body.ReadString

'Iterate through WebResources, be sure to set WebPage.UrlHost first
WebPage1.UrlHost = WebASP1.Request.Url
For i = 1 To WebPage1.Resources.Count
    If WebPage1.Resources.Item(i).UrlType = resImg Then
       'This WebResource is an image, so write to file
        blnResult = WebPage1.Resources(i).Get("C:\temp\img", True, 30000)
        If blnResult = True Then
            List1.AddItem WebPage1.Resources(i).UrlName & " is saved"
        End If
    End If
Next

Get a Page or File Code Example

The following example demonstrates a Get using the Web control. The page or file is saved to disk once it is retrieved. Progress is displayed in a log.

Private Sub buttonGet_Click()
GetPage("www.dart.com/myImage.jpg", App.Path & "\myImage.jpg")
End Sub

Private Sub GetPage(ByVal url As String, ByVal filename As String)
    'Reset the Request Message.
    Web1.Request.Content = ""

    'Get the page or file.
    Web1.Request.url = url
    Web1.Get

    'Save the file to disk.
    Web1.response.Body.filename = filename
End Sub

Private Sub Web1_Progress(ByVal Method As DartWebASPCtl.WebMethodConstants, _
    ByVal Status As DartWebASPCtl.WebStatusConstants, ByVal Count As Long, _
    ByVal Size As Long)
    'Show progress during the Get.
    If Method = webGet And Status = webReceiving Then
        textLog.Text = textLog.Text + CStr(Count) + " of " + CStr(Size)
        textLog.Text = textLog.Text + + " bytes transferred." + vbCrLf
    End If
End Sub

Post Data Code Example

The following example demonstrates a data Post using the Web control. The function creates a data string from the parameters passed in and submits it to the specified URL.

Private Function PostData(ByVal url As String, ByVal name As String, _
    ByVal company As String, ByVal quantity As Integer)
    'Set URL of the page to post to.
    Web1.Request.url = url

    'Add data variables to the Request.
    Web1.Request.Variables("name") = name
    Web1.Request.Variables("company") = company
    Web1.Request.Variables("quantity") = CStr(quantity)

    'Submit the data.
    Web1.Post

    'Return response.
    Dim response As String
    response = GetVersion(Web1.response.version) + " "
    response = response + CStr(Web1.response.Status)
    response = response + " " + Web1.response.StatusText + vbCrLf
    response = response + Web1.response.Header.All + vbCrLf
    response = response + Web1.response.Body.ReadString
    PostData = response
End Function

Private Function GetVersion(ByVal version As WebVersionConstants)
    GetVersion = ""
    If version = webHTTP10 Then GetVersion = "HTTP/1.0"
    If version = webHTTP11 Then GetVersion = "HTTP/1.1"
End Function

Upload a File Code Example

The following example demonstrates a file upload using the Web control. Uploading files requires a multipart MIME message, which are created automatically by the Web control. Contrast this with the PowerTCP Http control, which requires the developer to create the MIME message manually.

Private Function PostFile(ByVal url As String, ByVal filename As String)
    'Open file to read and post.
    Dim file As New DartStream
    file.FileMode = createExisting
    file.filename = filename
    file.Ref = "file1"
    file.Position = 0

    'Add file to files to post collection.
    Dim files As New DartStreams
    files.Add file
    Web1.Request.FilesToPost = files

    'Send Post and get server response.
    Web1.Request.url = url
    Web1.Post

    'Return response.
    Dim response As String
    response = GetVersion(Web1.response.version) + " "
    response = response + CStr(Web1.response.Status)
    response = response + " " + Web1.response.StatusText + vbCrLf
    response = response + Web1.response.Header.All + vbCrLf
    response = response + Web1.response.Body.ReadString
    PostData = response
End Function

Get Page Images Code Example

The following example demonstrates using the WebPage object to retrieve all images on a web page.

Private Sub Command4_Click()
GetImages "www.dart.com/default.aspx"
End Sub

Private Sub GetImages(ByVal url As String)
    'Get the page.
    Web1.Request.url = url
    Web1.Get

    'Set the web page source.
    Dim WebPage1 As New WebPage
    WebPage1.Source = Web1.response.Body.ReadString

    'Get and list images.
    Dim result As Boolean
    WebPage1.UrlHost = Web1.Request.url
    For i = 1 To WebPage1.Resources.Count
        If WebPage1.Resources.Item(i).UrlType = resImg Then
            result = WebPage1.Resources(i).Get(App.Path + "\images", True, 10000)
            If result = True Then
                listImages.AddItem WebPage1.Resources(i).UrlName
            End If
        End If
    Next
End Sub
