Use of Google Directions Service in VB.Net - asp.net

I am using Google Maps api v3..
According to This Documentation I can able to get the Path between any 2 points as in the Example.
Not I want to get the Same using VB.Net.. I want to get the same result in the server side processing (Means want to get the Path[lat lon pair]).
I have tried with the code
Dim lat As Double = 17.38489
Dim lon As Double = 78.486939
Dim lat2 As Double = 20.296095
Dim lon2 As Double = 85.82459
'For counter As Integer = 0 To 1
Try
Dim myURL As String = "http://maps.googleapis.com/maps/api/directions/json?origin=" & lat.ToString("0.000000") & "," & lon.ToString("0.000000") & "&destination=" & lat2.ToString("0.000000") & "," & lon2.ToString("0.000000") & "&sensor=false"
Dim myRequest As HttpWebRequest = WebRequest.Create(myURL)
myRequest.Method = "GET"
' Add request headers
myRequest.KeepAlive = True
myRequest.Accept = "*/*"
myRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0;)"
myRequest.Headers.Add("Accept-Language: en-us")
myRequest.Referer = "http://www.google.com/mapmaker?ll=16.303005,81.05464&spn=0.021583,0.040684&z=15"
myRequest.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-sg")
'myRequest.ContentType = "application/x-www-form-urlencoded"
Dim c As Char = "c"
Dim sb As New StringBuilder()
' Send the request and get the response
Dim myResponse As HttpWebResponse = myRequest.GetResponse
Dim reader As StreamReader = New StreamReader(myResponse.GetResponseStream())
sb.Append(reader.ReadToEnd())
reader.Close()
myResponse.Close()
Dim s As String = sb.ToString()
Dim ds As String = s
Response.Write(s)
Catch ex As Exception
End Try
Can any one Help me out..

I'm fairly sure doing this server-side is against the TOS? Plus there are limits to how many requests can be made from an IP address. What happens if you go over that limit? You need to check for error messages from Google and handle them gracefully. If you're paying for the service then there will probably be less restrictions.

Authenticating using OATH2 on Azure app registration works fine on IIS express, but fails in IIS

I have an application that I am trying to add a layer of SSO, authenticating against Azure AD app registration. The code works fine running in IIS Express, but fails with a 400 Bad Request whenever I attempt to run it from any IIS environment, including localhost.
I have a working function that requests an authorisation code, which works with no issues and the code is returned in the querystring. The issue happens in the next stage, where I use that code to retrieve the user's Sub ID from Microsoft. This is the code I have:
'Get the base azure values
Dim AzureClient As String = ClientInfo
Dim AzureSecret As String = AzureSecret
Dim AuthRedirectUri As String = "The address of the page"
Dim TenantID As String = AzureTenantID
Dim codeVerifier = Verifier string passed in earlier function
Dim httpWReq As HttpWebRequest = DirectCast(WebRequest.Create("https://login.microsoftonline.com/" & TenantID & "/oauth2/v2.0/token"), HttpWebRequest)
httpWReq.Method = "POST"
httpWReq.Host = "login.microsoftonline.com"
httpWReq.ContentType = "application/x-www-form-urlencoded"
Dim postData As String = "client_id=" & AzureClient
postData += "&scope=openid&20email&20profile"
postData += "&code=" & Code
postData += "&redirect_uri=" & AuthRedirectUri
postData += "&grant_type=authorization_code"
postData += "&code_verifier=" & codeVerifier
postData += "&client_secret=" & AzureSecret
Dim encoding As New ASCIIEncoding()
Dim byteArray As Byte() = encoding.GetBytes(postData)
' Set the ContentLength property of the WebRequest.
httpWReq.ContentLength = byteArray.Length
Using streamWriter = New StreamWriter(httpWReq.GetRequestStream())
streamWriter.Write(postData)
End Using
' Get the response.
Dim response As WebResponse = httpWReq.GetResponse() <--- This is where the 400 Bad Request is thrown in IIS, but not IIS Express
Dim responseString As String = New StreamReader(response.GetResponseStream()).ReadToEnd()
Dim o As OAuth2AccessTokenReponse = DirectCast(JsonConvert.DeserializeObject(responseString, GetType(OAuth2AccessTokenReponse)), OAuth2AccessTokenReponse)
Dim IDToken As String = o.id_token
Dim stream = IDToken
Dim handler = New JwtSecurityTokenHandler()
Dim jsonToken = handler.ReadToken(stream)
Dim tokenS = TryCast(jsonToken, JwtSecurityToken)
Dim subID = tokenS.Claims.First(Function(claim) claim.Type = "sub").Value
Return subID
I've compared the calls coming from both environments and they are identical. I have both localhost addresses (localhost IIS address and IIS Express port) so the only differences are the port numbers used in the redirect URI field.
Does anyone have any idea what could be throwing this?
Problem sorted. After much, much digging about I found that IIS was still supporting TLS1.0 - removed that and everything works fine now.

Downloading html as string

I am trying to download a webpage as string. Can someone please explain why the following code doesn't work?
Dim URL As String = "http://stackoverflow.com/"
Dim client As WebClient = New WebClient()
Dim data As Stream = client.OpenRead(URL)
Dim reader As StreamReader = New StreamReader(data)
Dim str As String = ""
str = reader.ReadLine()
Do While str.Length > 0
Console.WriteLine(str)
str = reader.ReadLine()
Loop
When I run it it never goes inside the loop.
Give this a shot...
Dim URL As String = "http://stackoverflow.com/"
Dim html As String = New WebClient().DownloadString(URL)
Better Solution (Releases resources that the network stack is using. Also ensure's (hope) the CLR cleans these up when needed.)
Using client As New WebClient()
html = client.DownloadString(URL)
End Using

Posted Form data using HtppWebRequest has not effect

I came across a website which seems simple enough that I was pretty confident that I will be able to read its data using HttpWebRequest and will be able to do the GET and POST requests. The GET requests are working fine. POST request also not generating any error but still the posted form data has no effect on the results which are returned. The form data posted have fields to filter the data as per dates but regardless the fact that every required data is posted the data returned is not filtered. I have added every header, form data and also added cookies with the request.
The url for the webpage is http://www.bseindia.com/corporates/Insider_Trading_new.aspx?expandable=0
This seems like a very ordinary website but as it is an aspx page and involves ViewState and Event Validation hence this was expected not to be very easy.
My first step was to analyze the site's GET and POST using Fiddler and this amazes me because Fiddler is not capturing any traffic for this url. I have tried Charles but that itself is not capturing this url. Other then this Url Fiddler and Charles both are capturing everything else. I also like to mention that when I called the Url from a console application using HttpWebRequest then both Fiddler and Charles captured it but they are not capturing it from Chrome, FireFox and Internet Explorer 11.
So I analyzed the Network activity using Developer tool in FireFox and everything was visible which includes (Headers, Parameters and Cookies). In Chrome no cookies were present. When I inspect the cookies by creating HttpWebRequest and got the response there were no cookies present. So something is really strange going o with this website.
I have somehow managed to create a simple function to create the request and get the response. What I am doing is that I am creating a GET request first and get the Website string and extract Viewstate, EventValidation etc from it. I use this information to be used in second HttpWebRequest which is a post. Now everything works fine and I get the response but not as expected. I want the records between two give dates and I have specified these dates in the form data but still the POST request does not return the filtered data. I have mentioned the function that I have created below and I will really appreciate any suggestions that why is this happening and how to handle this. To understand this has become a challenge to me as I cannot understand why this simple website is not showing up in Fiddler. (This uses Javascript Postback)
The code may look long and scary but rather it is very simple and straight forward.

You could consider running the site in a browser and using a tool to control the browser instead directly issuing GET/POST requests. This may be easier and slightly more robust than your current approach.
E.g. Selenium Web Driver http://www.seleniumhq.org/projects/webdriver/
You would load the page, set the values of the form fields (using css style selectors to find the appropriate fields) and then click the button. You can automate all of this and get the page source (unfortunately I don't think you can get the full html in it's current state, after javascript has run, but potentially you can use the api to get the elements you need).
Api documentation: http://seleniumhq.github.io/selenium/docs/api/dotnet/
You indeed should include ALL fields from the form, including hidden ones and ASP session identifier that is stored in cookies. That way you fully emulate browser' request and achieve your goal. To show what you have to submit - http://pastebin.com/AsSABgU6

Problems With Paypal Express Checkout Integration (WEBREQUEST)

So I was struggling with making head or tail out of the PayPal documentation and always felt that something was not right with my Webrequest.
So I stripped all the code back to basic and simply submitted the request via HTTP and the PLUS side is that I now get a response back from the PayPal sandbox server where ACK=Success and TOKEN=Valid-token-value-here there are some other variables returned too, such as CORRELATIONID and TIMESTAMP.
And hence so I tried some of the webrequest samples and I simply get a blank screen instead of being redirected to Paypal for the (sandbox) customer to complete payment.
So if anyone can post their WebRequest method that would be great.
Here is the code I used for my webrequest, I'm sure its wrong but cannot pinpoint where it is going wrong.
Also, when I run the code on my localhost during debugging, everything works fine and the call is completed with SUCCESS and a TOKEN is received.
When I run it live, I recieve Error Number 5 in the Error exception and also the text `Remote host failed to connect' in the STATUS DESCRIPTION.
THIS IS THE UPDATED CODE
Function MakeWebRequest(ByVal pUseSandbox As Boolean, ByVal pRequestMethod As String, ByVal pReturnUrl As String, ByVal pCancelUrl As String, ByRef pRtnStatus As String, ByRef pRtnStatusId As HttpStatusCode, ByRef pRtnResponseString As String) As Boolean

OK, so it's now clear that you're not getting any response from the server because your server isn't able to connect to PayPal's servers at all. Hence, you got no server-response and the message Unable to connect to the remote server. When I tested, I got a HTTP 200 response with the following body:
TIMESTAMP=2015-07-07T09:07:39Z&CORRELATIONID=7f4d2313c9696&ACK=Failure&VERSION=93.0&BUILD=17276661&L_ERRORCODE0=10002&L_SHORTMESSAGE0=Authentication/Authorization Failed&L_LONGMESSAGE0=You do not have permissions to make this API call&L_SEVERITYCODE0=Error
Obviously that's because I tested with a blank username and password.
So, something is wrong with your server setup that's preventing you from making outside connections, either at the IIS level or due to your firewall configuration.
Without physically being present at your machine, there's not a lot we can do to track down what's blocking it, but you can try opening HTTP requests to other public websites like Google.com and see if those succeed.

Paypal Express Payment Execution

I'm developing in vb.net and as of right now I am not using any API's to receive transaction details I have only been using IPN and PDT variables to get my details however I began to notice that, when using Paypal Sandbox to test, after I go through the process of check out, I do receive all the variables of the details but in my test account, there are no transactions shown.
Do I need to be using the REST API in order to actually approve and execute the payment for the transaction in order to complete a transaction? I had assumed that the entire transaction had been completed successful since I was getting all of the details back but now that I noticed there aren't any transactions showing in my account I'm not so sure whats going on?
Here is the code I have been using to view transaction details
