Hello Everyone,
I am having problems with my VB 2008 Express project. Here is a quick outline of what I have done.
Used WSDL Tool to create a file named “Racing.vb”.
I then added this file to my project by using Project>Add Existing Item.
This added a file to my Solution Explorer Window named “Racing.vb”
I then searched the new file to find the method I would use to send a web request. This method is copied straight from the Racing.vb file:
'''<remarks/>
<System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://direct.tab.com.au/LiveOdds/MeetingSummary", RequestNamespace:="http://direct.tab.com.au/LiveOdds/", ResponseNamespace:="http://direct.tab.com.au/LiveOdds/", Use:=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)> _
Public Function MeetingSummary(ByVal Key As String, ByVal Jurisdiction As String, ByVal [Date] As String, ByVal TypeCode As String) As System.Xml.XmlElement
Dim results() As Object = Me.Invoke("MeetingSummary", New Object() {Key, Jurisdiction, [Date], TypeCode})
Return CType(results(0),System.Xml.XmlElement)
End Function
From this I wrote the following code as the request for the web service:
Dim objMSInfo As New Racing()
Dim MSResult As String
MSResult = objMSInfo.MeetingSummary(myKey, strJ, strRD, strTC)
As soon as I had finished typing the last line of this code, I got the error message in the Error Box, saying:
Value of type 'System.Xml.XmlElement' cannot be converted to 'String'.
So figuring that the returned values could not be declared as a String, I decided to change my code a little and see if I could return it as an Xml Document, so I changed my code to the following:
Dim objMSInfo As New Racing()
Dim MSResult As New XDocument
MSResult = objMSInfo.MeetingSummary(myKey, strJ, strRD, strTC)
This brings back the same error message, only this time saying:
Value of type ‘System.Xml.XmlElement’ cannot be converted to ‘XDocument’
So I am now resigned to asking for the help of someone who has been through this and can see where I am going wrong. I am migrating up from VB4, which I learnt a few years ago now, to VB.Net using the 2008 Express edition, and so I am a bit lost with this Xml Stuff.
Oh and for clarification, this is the structure of the data that should be coming back from the MeetingSummary request:
- <Meetings Jurisdiction="NSW">
- <Summary MID="SR_20040705">
<VenueName>COFFS HARBOUR (NSW)</VenueName>
<Type>R</Type>
<Events>12</Events>
<track>GOOD</track>
<weather>FINE</weather>
- <Races>
- <Race RID="SR_20040705_01">
<Name>MARES SC PLTE</Name>
<Distance>1200M</Distance>
<Class/>
<RunnerNo Acceptors="14">12</RunnerNo>
<JumpTime>16:52</JumpTime>
<TimeToJump>+03:01:00</TimeToJump>
<RaceStatus>Betting Open</RaceStatus>
</Race>
+ <Race RID=" SR_20040705_2">
+ <Race RID=" SR_20040705_3">
+ <Race RID=" SR_20040705_4">

+ <Race RID=" SR_20040705_7">
+ <Race RID=" SR_20040705_8">
+ <Race RID=" SR_20040705_9">
</Races>
</Summary>
+ <Summary MID="MR_20040705">
+ <Summary MID="MH_20040705">
+ <Summary MID="SH_20040705">
+ <Summary MID="BH_20040705">
+ <Summary MID="SG_20040705">
+ <Summary MID="PG_20040705">
+ <Summary MID="MG_20040705">
</Meetings>
Can anyone shed some light on how I can display this information in my program. I intend to declare each element as a variable so that I can display them in a particular way. I can also paste the entire Racing.vb file if needed, however it is a really big file and so for now to save space I will not include it unless needed.
Thanx in advance to anyone who can help guide me with this problem.
