This function gets a url as input and returns keywords that relevant to that url as output in the following format:
KeywordName1###CPC###SearchVolume
KeywordName2###CPC###SearchVolume
for some reason no matter what website I type in it returns 180 results,
Im aware that pageSize is set to 180,
In-fact if you lower pageSize to 179, you only get 179 results, the problem is that i cant get more then 180 results whatsoever..
Optional help: also why the CPC value returned in the first function is different from the CPC value returned from that function:

how can I get EXCAT CPC in the first function?
because now only the second function return good CPC and the
first function return the wrong CPC(checked in israeli adwords frontend)

If I manually put my address in for EmailMessage.To.Add(GetDelimitedField(x, strEmailRep, ";")) It sends me the message just fine. However If I use the code as is below which is using a list that looks like ;email1#mail.com;email2.mail.com

You can split the list easier using string.Split:

Any Ideas on why this is going wrong?????
You aren't attaching your _eCourse to your context so it won't update it.
UpdateModel I don't believe is required here at all as that simply takes your posted form values an assigns to your model which you already have since eCourse is a parameter. Do something like (on phone here sorry)
DB.Entry(_eCourse).State = EntityState.Modified
And then save changes
I want to get latlng object in google maps in advance. Basically my json result is returning array of address which I need to convert to glatlng to use for markers. But if i will use GeoCoder object then it will send asynch request which I don't want.
Is there any way other than GeoCoder object to convert an address string to GLatLng object?
You can take a look at the json object returned by any query to the maps api.
Then you use the json serializer in system.web.extensions to serialize the json into a class that you have to create from the JSONresponses which you analyze manually.
Note that you can get localized language return results by adding this to the http web request:
wrHTTPrequest.UserAgent = "Lord Vishnu/Transcendental (Vaikuntha;Supreme Personality of Godness)"
wrHTTPrequest.Headers.Add("Accept-Language:" + System.Globalization.CultureInfo.CurrentCulture.Name)
wrHTTPrequest.ContentType = "text/html"
Edit:
The example, from one of my files (remove all the SharpMap.Map stuff, it requires an external assembly.
