WCF / ASMX :: Consuming Freight Price Calculation Webservice?

how to consume a webservice from Brazilian Correios (kind of USA Fedex).

The Web Service address is [URL]

The instructions says that I need to use the method CalcPrecoPrazo and send those parameters listed below (I already filled the variables with the correct content to help you use that webservice).

Dim nCdEmpresa As String = ""
Dim sDsSenha As String = ""
Dim nCdServico As String = "41106"
Dim sCepOrigem As String = "87047130"
Dim sCepDestino As String = "80610320"
Dim nVIPeso As Decimal = 1
Dim nCDFormato As Integer = 1
Dim nVIComprimento As Decimal = 20
Dim nVIAltura As Decimal = 30
Dim nVILargura As Decimal = 30
Dim nVIDiametro As Decimal = 0
Dim sCdMaoPropria As String = "N"
Dim nVIValorDeclarado As Decimal = 0
Dim sCdAvisoRecebimento As String = "N"

The result will be send by the parameter RESULTADO.SERVICOS in a array format.
