SharePoint 2010: show hidden columns with WebService

I create a list, add 2 columns and insert 2 items via c# Webservice. In SharePoint I cannot see the 2 columns, only Title. When I edit the items, I see the other columns. In SharePoint I can change the view to see the 2 columns. But how to change the view with Webservice?
I try this:
private void SetView(string listName, string viewName, String[] arr)
{
AllViews.Views viewService = new AllViews.Views();
viewService.Credentials = System.Net.CredentialCache.DefaultCredentials;
//from msdn
//string strQuery1 = "<Where><Gt><FieldRef Name=\"Title\" />" +
// "<Value Type=\"Title\"></Value>" + "</Gt></Where>" +
// "<OrderBy><FieldRef Name=\"Title\" /></OrderBy>";
string strQuery = "<Query><Where><IsNotNull><FieldRef Name=\"Title\" />" +
"</IsNotNull></Where></Query>";
string strRowLimit = "150";
string strViewFields = "";
int count = arr.Length;
for (int i = 0; i < count; i++)
{
strViewFields += "<FieldRef Name=\'" + arr[i] + "\'/>";
}
System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
System.Xml.XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
System.Xml.XmlNode ndRowLimit = xmlDoc.CreateNode(XmlNodeType.Element, "RowLimit", "");
System.Xml.XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
ndQuery.InnerXml = strQuery;
ndRowLimit.InnerXml = strRowLimit;
ndViewFields.InnerXml = strViewFields;
XmlNode retNode = viewService.AddView(listName, viewName, ndViewFields, ndQuery, ndRowLimit, "HTML", false)
}
All without error, but columns hidden in the list. Maybe the query is wrong. Or the way that I use. Any tipps for me? Searching results are all about the SharePoint.dll, but I need a way with Webservice.

Solution
Change strQuery to:
string strQuery = "<Where><IsNotNull><FieldRef Name=\"Title\" />" +
"</IsNotNull></Where>";
// is in Node ndQuery, dont need it again. Maybe a dirty trick to hide new Columns
Set the new View as default with UpdateView. Be sure to use the GUID from the view.
For viewProperties only the prop that you want to change
string strProp = "DefaultView =\"TRUE\"";
All works fine. Have a nice weekend.

GetListItems() causes a 401 error but Checkout() works

I want to get the contents of a Sharepoint 2007 list via web service. I'm using this code, which I mostly copied from the MSDN page for GetListItems:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
namespace testGetListItems
{
class Program
{
static void Main(string[] args)
{
sharepoint.Lists listService = new sharepoint.Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlDocument xmlDoc = new System.Xml.XmlDocument();
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode ndQueryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
ndQueryOptions.InnerXml =
"<IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns>" +
"<DateInUtc>TRUE</DateInUtc>";
ndViewFields.InnerXml = "<FieldRef Name='Field1' /> <FieldRef Name='Field2'/>";
ndQuery.InnerXml = "<Where><And><Gt><FieldRef Name='Field1'/>" +
"<Value Type='Number'>5000</Value></Gt><Gt><FieldRef Name='Field2'/>" +
"<Value Type= 'DateTime'>2003-07-03T00:00:00</Value></Gt></And></Where>";
try
{
bool checkoutResult=listService.CheckOutFile("http://sharepoint/sites/mysite/myFile.xlsx", "false", null);
XmlNode ndListItems =
listService.GetListItems("Test List", null, ndQuery,
ndViewFields, null, ndQueryOptions, null);
}
catch (System.Web.Services.Protocols.SoapException ex)
{
Console.WriteLine("Message:\n" + ex.Message + "\nDetail:\n" +
ex.Detail.InnerText +
"\nStackTrace:\n" + ex.StackTrace);
}
}
}
}
The call to CheckOutFile() works correctly. But the GetListItems() call gives me this error:
An unhandled exception of type 'System.Net.WebException' occurred in System.Web.Services.dll
Additional information: The request failed with HTTP status 401: Unauthorized.
I don't understand why CheckOutFile() succeeds but GetListItems() fails, especially because the document that I'm checking out is in the list that's being accessed by GetListItems().

UPDATE: This worked in a test console app, but not in my main application. Leaving this answer up for now, but I'm not going to accept it until I get this fixed.
It turned out the problem was with the URL of the web service. Even though I had added it as:
http://sharepoint/sites/mySite/_vti_bin/Lists.asmx
the app.config file had it listed as:
http://sharepoint/_vti_bin/Lists.asmx
This remained a problem even after I deleted the reference and re-added it; I had to change the app.config contents manually. Once I'd done so, the GetListItems() call succeeded.

You must set a user and password who can get the items in the library/list this way (for me it works, you could try):
public string GetIDFromList(string parameter)
{
string retorno = "";
try
{
string path = "http://www.test.com/web/";
// Reference to the SharePoint Lists web service:
WSSharePointCSCLists.Lists listsWS = new WSSharePointCSCLists.Lists();
listsWS.Url = path + "_vti_bin/lists.asmx";
listsWS.Credentials = GetUserCredential();
string listName = "MyList";
string viewName = "";
//string webID;
string rowLimit = "500";
// Web ID:
webID = "098304-9098asdf-qwelkfj-eoqiula";
XmlDocument xmlDoc = new System.Xml.XmlDocument();
// Query em CAML (SharePoint):
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields =
xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode ndQueryOptions =
xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
ndQueryOptions.InnerXml =
"<IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns>" +
"<DateInUtc>TRUE</DateInUtc>" +
"<ViewAttributes Scope=\"RecursiveAll\" />";
ndViewFields.InnerXml = #"<FieldRef Name='Title' />
<FieldRef Name='ID' />";
string caml =
String.Format(
#"<Where>
<Contains>
<FieldRef Name='MyColumn' />
<Value Type='Text'>{0}</Value>
</Contains>
</Where>",
parameter);
ndQuery.InnerXml = caml;
XmlNode retornoWS = listsWS.GetListItems(listName, null, ndQuery,
ndViewFields, rowLimit,
ndQueryOptions, webID);
retorno = retornoWS.InnerXml;
}
catch (Exception ex)
{
Debug.WriteLine("Exception: " + ex.Message);
throw;
}
return retorno;
}
public NetworkCredential GetUserCredential()
{
return new System.Net.NetworkCredential("<username>",
"<password>",
"<domain>");
}

Query to get files URL from sharepoint

Is it possible to get a perticular file from sharepoint instead of getting all files at onlce?
In below query when I queryNode is empty I am getting all the files but when queryNode is commented query I am not getting any file.
What is missing here?
XmlDocument xmlDoc = new XmlDocument();
XmlNode queryNode = xmlDoc.AppendChild(xmlDoc.CreateNode(XmlNodeType.Element, "Query", ""));
//queryNode.InnerXml = "<Where>" +
// " <Eq>" +
// " <FieldRef Name='FileLeafRef'></FieldRef>" +
// " <Value Type='File'>" + SomeFileName + "</Value>" +
// " </Eq>" +
// "</Where>";
queryNode.InnerText = "";
XmlDocument xmlDoc1 = new XmlDocument();
XmlNode viewNode = xmlDoc.AppendChild(xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", ""));
viewNode.InnerXml = "";
XmlDocument xmlDoc2 = new XmlDocument();
XmlNode optionsNode = xmlDoc.AppendChild(xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", ""));
optionsNode.InnerText = "";
XmlNode nodeListItems = wsList.GetListItems("Documents",
"",
queryNode,
viewNode,
"1",
optionsNode,
null);

This will retrieve all items in a list with a filename of "filename" only.
var list = web.Lists["ListTitle"];
var fileQuery = new SPQuery();
fileQuery .ViewAttributes = "Scope=\"Recursive\"";
string strQuery = "<Where>" +
"<Eq>" +
"<FieldRef Name=\"FileLeafRef\"/>" +
"<Value Type=\"Text\">" + fileName + "</Value>" +
"</Eq>" +
"</Where>";
fileQuery .Query = strQuery ;
SPListItemCollection collListItems = list.GetItems(fileQuery );

Can't get inner text from FQL using Xpath C#

I'm trying to get the inner text from a XML tag called sharecount, I need to get it by the normalized_url tag like so:
string ShareCount;
string Url = "'" + "http://www.example.com/Article.aspx?id=" + GuideID + "'";
XmlNode Node;
try
{
//return Share count (using Xpath).
XmlDoc.SelectSingleNode("fql_query_response/link_stat[normalized_url=" + Url + "]/share_count");
ShareCount = XmlDoc.InnerText;
int.TryParse(ShareCount, out Value); //Turn string to int.
return Value;
}
catch
{
return 0;
}
and this is the XML:
<fql_query_response xmlns="http://api.facebook.com/1.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" list="true">
<link_stat>
<url>http://www.example.com/Article.aspx?id=1909</url>
<normalized_url>http://www.example.com/Article.aspx?id=1909</normalized_url>
<share_count>11</share_count>
<like_count>3</like_count>
<comment_count>0</comment_count>
<total_count>14</total_count>
<commentsbox_count>8</commentsbox_count>
<comments_fbid>10150846665210566</comments_fbid>
<click_count>0</click_count>
</link_stat>
</fql_query_response>
<link_stat>
<url>http://www.example.com/Article.aspx?id=1989</url>
<normalized_url>http://www.example.com/Article.aspx?id=1989</normalized_url>
<share_count>11</share_count>
<like_count>3</like_count>
<comment_count>0</comment_count>
<total_count>14</total_count>
<commentsbox_count>8</commentsbox_count>
<comments_fbid>10150846665210566</comments_fbid>
<click_count>0</click_count>
</link_stat>
</fql_query_response>
The thing is i got in the return value: "www.example.com/Article.aspx?id=1132http://www.example.com/Article.aspx?id=190900000101502138970422760" what am i doing wrong? thanks!

The problem is you are Selecting a single node but obtaining the content from the root element. On top of that, you have a root namespace, therefore use of NameSpaceManger for searches is required. Try this sample:
string GuideID = "1989";
string Url = "'" + "http://www.example.com/Article.aspx?id=" + GuideID + "'";
var XmlDoc = new XmlDocument();
XmlDoc.Load(new FileStream("XMLFile1.xml",FileMode.Open,FileAccess.Read));
var nsm = new XmlNamespaceManager(XmlDoc.NameTable);
nsm.AddNamespace("s", "http://api.facebook.com/1.0/");
var node = XmlDoc.SelectSingleNode("s:fql_query_response/s:link_stat[s:normalized_url=" + Url + "]/s:share_count", nsm);
var ShareCount = node.InnerText;
And here is the LINQ way with same namespace manager and an XPathSelector.
XDocument xdoc = XDocument.Load(new FileStream("XMLFile1.xml", FileMode.Open, FileAccess.Read));
var lnode = xdoc.XPathSelectElements("s:fql_query_response/s:link_stat[s:normalized_url=" + Url + "]/s:share_count",nsm).First();
var ret = lnode.Value;

is there any easy wasy to convert the XML output from sharepoint GetListItems() to a DataTable

i am able to retrieve data from sharepoint
com.sharepoint2.Lists lists = new Lists();
lists.Credentials = new System.Net.NetworkCredential("user", "pwd", "domain");
lists.Url = "http://sharepoint2.company.com/sites/mysite/_vti_bin/Lists.asmx";
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode ndQueryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
XmlNode listitems = lists.GetListItems("MyList", null, ndQuery, ndViewFields, null,ndQueryOptions, null);
i now have this huge XML blog with all of my data. Is there any easy way to convert this to a datatable so i treat this like a matrix to loop through each row ??
i tried something like this but it doesn't seem to work:
System.IO.StringReader sr = new System.IO.StringReader(listitems.OuterXml);
XmlTextReader tr = new XmlTextReader(sr);
DataSet ds = new DataSet("resultDataSet");
ds.ReadXml(tr);

Ahh, xml returned from GetListItems is almos the same as SPListItemCollection.Xml. I have an extension method that converts this XML into datatable.
You can just try to use ConvertZRowToRegularXml method on your returned XML - and you would get back an XML that DataTable understands.
Credits for the solution goes to Vincent Rothwell.

You should pass the XmlNodeType to the XmlTextReader like this:
DataSet ds=new DataSet();
using(var reader=new XmlTextReader(listItems.OuterXml,XmlNodeType.Element,null))
{
ds.ReadXml(reader);
}
Concering the object model vs the web services: The usual way to create web parts, event receivers etc. is to use Sharepoint's server object model. The web services are not used that much, because they are a bit cumbersome. In Sharepoint 2010 a new client object model and the WCF Data Services makes things a LOT easier and the old ASMX web services are considered deprecated.
BUT Sharepoint Online is actually a 2007 version that doesn't allow server-side code, so AJAX and the ASMX web services are the only way to customize and communicate with a Sharepoint Online site. This has brought the ASMX services to the front just as they became deprecated. Go figure.
