Thank you in advance for any and all assistance.

I'm trying to create a call to a web page to validate and register software.
The code I'm using is:

    Private Sub OK_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles OK.Click
        Dim WebRequest As HttpWebRequest
        Dim instance As HttpWebRequest =
WebRequest.Create("https://www.plimus.com/jsp/validateKey.jsp?action=REGISTER&productId=####&key=LicenseTextBox.text&uniqueMachineId=GetOSProductKey")
    End Sub

The error I'm getting is that .Error   
1    'Create' is not a member of
'EZTechTools.LoginForm1.HttpWebRequest'.    E:\EZTechToolsProMo\EZTechTools\LoginForm1.vb    119    42    EZTechToolsPro
HELP Please!

Show quote Hide quote This looks like a name collision.  There is in .net a shared method, namely
    System.Net.WebRequest.Create
And you have a variable, WebRequest of type HttpWebRequest.
So, when you code WebRequest.Create, it sounds like you want the first and
not the second.  If that is true, then change WebRequest.Create to
System.Net.WebRequest.Create.  In any event, I suggest you change your
declaration
    Dim WebRequest As HttpWebRequest
to a different name (ie change WebRequest to something else).  It is poor
form to use a class name for a variable name.  It is like coding
    Dim String as Integer.

Private Sub OK_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles OK.Click
        If Username.Text Is Nothing And License.Text Is Nothing Then
            MessageBox.Show("Please enter your registered name.")
            Username.Focus()
        ElseIf Username.Text <> "" And License.Text Is Nothing Then
            MessageBox.Show("Please enter your registration number:
###-####-####-####")
            License.Focus()
        Else
            Dim myWebRequest As Net.WebRequest
            Dim instance As Net.WebRequest =
Net.WebRequest.Create("https://www.plimus.com/jsp/validateKey.jsp?action=REGISTER&productId=#####&key="
+ "License.text" + "&uniqueMachineId=" + GetOSProductKey())
            Dim response As Net.HttpWebResponse = request.GetResponse()
            Dim reader As StreamReader = New
StreamReader(response.GetResponseStream())
            Dim str As String = reader.ReadLine()
            Do While str.Length > 0
                str = str + reader.ReadLine()
            Loop

        End If
    End Sub

now the error that I'm getting is:
Error    4    Name 'request' is not
declared.    E:\EZTechToolsProMo\EZTechTools\frmRegistration.vb    122    51    EZTechToolsPro

Please someone help me fix this. I've been trying to get this resolved for
nearly three days now.

Hello Michael,

I think your code logic is absolute right. The error you encounter is
caused by some tiny syntax mistakes.  e.g ,

The following statement in your code

Dim response As Net.HttpWebResponse = request.GetResponse()

should be changed to

Dim response As Net.HttpWebResponse = instance.GetResponse()

since you never declared a variable named "request".

Here is a complete code sinppet on using the webrequest to query a remote
http document:

===============================

Protected Sub btnRequest_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btnRequest.Click

        Dim request As Net.HttpWebRequest
        Dim response As Net.HttpWebResponse

        Dim url As String = "http://www.microsoft.com"

        request = Net.WebRequest.Create(url)


        request.Method = "Get"

        'optional security setting
        request.Credentials = Net.CredentialCache.DefaultCredentials

        'optional proxy setting
        request.Proxy = New Net.WebProxy("jpnproxy", 80)

        response = request.GetResponse()

        Dim sr As IO.StreamReader = New
IO.StreamReader(response.GetResponseStream())

        Dim responseContent As String = sr.ReadToEnd()

        sr.Close()
        response.Close()

        'content is in responseContent variable

    End Sub
===================================

Here are some other web article describing using webrequest component to
access remote http document:
