Question

I am unable to write any records to my database using a web service. Service is set up OK and can access it via uri and also query my database via the service using a simple page i created.

When it comes to writing to the database, I am not getting any errors, and the instance of my WebClient which is populated with variables to write to the db is holding all the variables OK but when it comes to actually writing to the db (see below code) nothing seems to happen except that the Member ID of the last existing member added to the database is returned.

        'assign all abMem fields to values within form to write to database
        newMem.Title = ddTitle.SelectedValue
        newMem.Initials = txtInitials.Text
        newMem.Surname = txtSurname.Text
        newMem.Address1 = txtAdd1.Text
        newMem.Address2 = txtAdd2.Text
        newMem.Address3 = txtAdd3.Text
        'etc etc .... additional fields have been removed

        Try
            cc.Open()
            cc.CreateMember(newMem)
            returnMem = cc.GetMember(newMem)
            MesgBox(returnMem.MemberID & " - Member Created")
            cc.Close()
        Catch cex As CommunicationException
            MesgBox("CommEX - " & cex.Message)
            cc.Abort()
        Catch tex As TimeoutException
            MesgBox("TimeEX - " & tex.Message)
            cc.Abort()
        Finally
            MesgBox("Closed the Client")
        End Try

When i run the above, I’ve noticed in the log file for the service (in the system32 folder on my server) that 2 requests are made each time – presumably one for where I am trying to add a record and the other I would think would be the request for the ID of this member (which isn’t created, hence why I believe it it is simply returning the last successful entry in the table).

I know there isn’t a problem with the actual web service as there is another user successfully able to add to the db via the service (unfortunately I am unable to simply copy their set-up as they are hitting it via a php page) so i know there is a problem somewhere in my code.

Is cc.CreateMember(newMem) the correct syntax for passing a member’s details to the function in the webservice is what I am wondering?

Answer 1

I’ve re-wrote the code (seems identical to above) and republished the web service. Seems to be working OK now so I must have had some silly mistake somewhere!
