Microsoft CRM 3.0 - Quote To Order converting. (VB.NET)

Well, this goes under the "not very obvious" category with the SDK. You
first need to "win" the Quote and to do that, you first need to setup a
"quoteclose" object that will be the activity related to the "win". Then
you can create the Order from it.

Public Function ConvertToOrder(ByVal QuoteId As String) As String
Try
Dim WsCrm As New WsCRM30.CrmService
WsCrm.Credentials = CType(HttpContext.Current.Application("Credentials"), System.Net.ICredentials)
'***********Activate Quote
Dim SSQR As WsCRM30.SetStateQuoteRequest = New WsCRM30.SetStateQuoteRequest
SSQR.EntityId = New Guid
SSQR.EntityId = New Guid(QuoteId)
SSQR.QuoteState = WsCRM30.QuoteState.Active
SSQR.QuoteStatus = -1
Dim Resp As WsCRM30.SetStateQuoteResponse = CType(WsCrm.Execute(SSQR), WsCRM30.SetStateQuoteResponse)
'***************************

' Create Quoteclose object
Dim QC As WsCRM30.quoteclose = New WsCRM30.quoteclose
QC.quoteid = New WsCRM30.Lookup
QC.quoteid.Value = New Guid(QuoteId)
QC.quoteid.type = WsCRM30.EntityName.quote.ToString()

'***********"Win" Quote
Dim WQR As WsCRM30.WinQuoteRequest = New WsCRM30.WinQuoteRequest
WQR.QuoteClose = QC
WQR.Status = -1
Dim Resp2 As WsCRM30.WinQuoteResponse = CType(WsCrm.Execute(WQR), WsCRM30.WinQuoteResponse)

Dim QToSo As WsCRM30.ConvertQuoteToSalesOrderRequest = New WsCRM30.ConvertQuoteToSalesOrderRequest
QToSo.ColumnSet = New WsCRM30.AllColumns
QToSo.QuoteId = New Guid(QuoteId)
QToSo.ReturnDynamicEntities = False

Dim RQToSo As WsCRM30.ConvertQuoteToSalesOrderResponse = New WsCRM30.ConvertQuoteToSalesOrderResponse
RQToSo = CType(WsCrm.Execute(QToSo), WsCRM30.ConvertQuoteToSalesOrderResponse)

Dim Result As String = "{" + CType(RQToSo.BusinessEntity, WsCRM30.salesorder).salesorderid.Value.ToString + "}"

Dim WSOR As WsCRM30.UnlockSalesOrderPricingRequest = New WsCRM30.UnlockSalesOrderPricingRequest

Dim RespSO As WsCRM30.UnlockSalesOrderPricingResponse = New WsCRM30.UnlockSalesOrderPricingResponse

Return Result
