Hi,

I'm working on a project which includes XML WebServices and Windows Form
application.

The Windows Form application will call the XML WebServices to retrieve data
from database. The data will be returned as DataSet.

Now, here's the problem. On .NET Framework 1.1, if any rows in the dataset
returned contain errors (marked by calling the SetColumnError() method or
setting the RowError property of the DataRow), I get the following error
message in the Windows Form application,

"There is an error in XML doument (x,xxxxxxx)"

If I forced the Windows Form application to run on .NET Framework 1.0,
everything works fine.

Here's the partial code for the WebService project

Code:

<WebMethod()> _
Public Function RetrieveDataSet() As DataSet
Dim ds As New DataSet
Dim dt As New DataTable
Dim row As DataRow
Dim i As Integer

dt.TableName = "TestTable"
dt.Columns.Add("TestColumn1", GetType(String))
dt.Columns.Add("TestColumn2", GetType(Integer))

ds.DataSetName = "TestDataSet"
ds.Tables.Add(dt)

For i = 0 To 10
row = dt.NewRow
row("TestColumn1") = "This is row " & i
row("TestColumn2") = i
dt.Rows.Add(row)

' The following code trigger the error after the DataSet
' is returned to the calling Window Form application
row.SetColumnError("TestColumn1", "Error message here")
Next

Return ds
End Function



For the Windows Form application, you need to insert a datagrid control
(assumed as datagrid1). It will look something like this,

Code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim ws As localhost.Service1
Dim ds As DataSet

Try
ws = New localhost.Service1
ds = ws.RetrieveDataSet

Me.DataGrid1.SetDataBinding(ds.Tables(0), "")
Catch ex As Exception
MsgBox(ex.Message)
Finally
If (Not (ws Is Nothing)) Then
ws.Dispose()
End If
End Try
End Sub


I really hope someone could help me out with this one.

Thanks in advance.

ps: Please, before anyone reply to state that I did not choose the
appropriate groups when making this post a crossposts post, please know that
I'm currently in blind on what is causing this error. Is it the WebService?
or is it the ADO .Net? or is it Windows Form application? or is it VB .Net?
Well, it has something to do with WebService as it only happens to the
DataSet returned by WebService. It also has something to do with ADO .Net as
I'm using DataSet. And it definitely has something to do with Windows Form
application as if I force the Windows Form application project to run on
..Net Framework 1.0, everything works fine.

I (as well as others) have posted multiple times in different groups and
have yet to recieve any response on this issue. It is extremely frustrating
because it is easy to reproduce and yet I have seen no one from MS offer to
look into it or acknowlege it. It would at least be comforting to hear them
say "yes, there is a problem and we are looking into it" but I haven't even
got that yet. Being able to set RowErrors is a powerful tool but as you see,
it will not work through web services returning a dataset as it will produce
the message you indicate below.

I guess today I searched on the right keywords - I have looked before but

Does this mean I have to pay US99 to get the fix?

(sorry about that last post, I hit the wrong key)

Anyway, hopefully not. From the same page:

"NOTE: In special cases, charges that are ordinarily incurred for
support calls may be canceled if a Microsoft Support Professional
determines that a specific update will resolve your problem. The usual
support costs will apply to additional support questions and issues that
do not qualify for the specific update in question."

It remains to be seen what they consider a "special case".
Unfortunately, it sounds like they still charge you up-front, and then
maybe refund it later...

I live in Malaysia, US99 is about RM396 which is 1/3 of my monthly salary.
Anyway, why should Microsoft do that? It is a fix to their own mistakes
(bugs). Sigh...
