QuickFix/n - Custom fields inside Logon

I'm trying to create an initiator based on QuickFix/n.
My counterpart (server) demand the logon message to carry two custom fields.I already added those to the Data Dictionary, in the Fields as well as in the Logon message.
In the code i can manipulate the message to add the username and password, but i can't find how to load custom fields.
Here are some excerpts from what i've done so far:
TradeClientApp.cs
...
public void ToAdmin(Message message, SessionID sessionID)
{
QuickFix.SessionSettings settings = new QuickFix.SessionSettings("./initiator.cfg");
List<SessionID> sids = settings.GetSessions().ToList();
Dictionary settingsDict = settings.Get(sids.First());
var appName = settingsDict.GetString("ApplicationName");
var userType = settingsDict.GetString("UserType");
if (message.GetType() == typeof(QuickFix.FIX44.Logon))
{
message.SetField(new Username("USERNAME"));
message.SetField(new Password("PASSWORD"));
message.SetField(new QuickFix.Fields.ResetSeqNumFlag(true));
//tag 9933
message.SetField(new RawData(string.Format($"9933={appName}")));
//tag 20110
message.SetField(new RawData(string.Format($"20110={userType}")));
}
}
The initiator.cfg file:
[DEFAULT]
UseDataDictionary=Y
DataDictionary=./spec/FIX44.xml
FileStorePath=store
FileLogPath=log
ConnectionType=initiator
ReconnectInterval=60
[SESSION]
BeginString=FIX.4.4
SenderCompID=USERNAME
ResetSeqNumFlag=Y
Username=USERNAME
Password=PASSWORD
TargetCompID=TARGETCOMPID
StartTime=12:30:00
EndTime=23:30:00
HeartBtInt=10
ApplicationName=app-name
UserType=V
SocketConnectPort=446
SocketConnectHost=SERVERHOST
Inside the FIX44.XML
<message name="Logon" msgtype="A" msgcat="admin">
<field name="EncryptMethod" required="Y" />
<field name="HeartBtInt" required="Y" />
<field name="RawDataLength" required="N" />
<field name="RawData" required="N" />
<field name="ResetSeqNumFlag" required="N" />
<field name="NextExpectedMsgSeqNum" required="N" />
<field name="MaxMessageSize" required="N" />
<group name="NoMsgTypes" required="N">
<field name="RefMsgType" required="N" />
<field name="MsgDirection" required="N" />
</group>
<field name="TestMessageIndicator" required="N" />
<field name="Username" required="N" />
<field name="Password" required="N" />
<field name="ApplicationName" required="N" />
<field name="UserType" required="N" />
</message>
<fields>
...
<field number="9933" name="ApplicationName" type="STRING"/>
<field number="20110" name="UserType" type="STRING" />
</fields>
</fix>
When i try to connect i get this log:
<outgoing> 8=FIX.4.49=12035=A34=149=USERNAME52=20191008-21:19:41.49856=TARGETCOMPID96=20110=V98=0108=10141=Y553=USERNAME554=PASSWORD10=097
Using the RawData as shown in my example, the message carries 20110=V as RawData, which is tag 96, which doesn't help me.
I already tried inside ToAdmin:
message.Header.SetField(new StringField(QuickFix.Fields.Tags.UserType, ""));
or
message.SetField(new QuickFix.Fields.UserType(true));
but neither work.
How on earth do you add custom fields to the logon message?

I think you are getting the RawData data type wrong. That is literally meant for raw data, not for Strings that follow the default encoding.
From the spec:
string field containing raw data with no format or content
restrictions. Data fields are always immediately preceded by a length
field. The length field should specify the number of bytes of the
value of the data field (up to but not including the terminating SOH).
I am not so familiar with the C# implementation of QuickFIX but you should simply be able to add these fields with the specific tag number, e.g.
message.SetField(new StringField(20110, "V"));
I hope there are no syntax errors, but you should get the idea.
Edit: I see you are manually setting the ResetSeqNum field on the Logon message. This is discouraged. quickFIX/n should deal with this when you set ResetSeqNum=Y in the settings (you already have that setting).

How to insert an XML File into Another XML File at Specific Node C#

I have two XML Files ,the first one is and Named as XMLTemplate
<DataSources>
<DataSource Name="XXXX">
</DataSource>
<DataSource Name="ABC">
</DataSource>
</DataSources>
<DataSets>
<DataSet Name="abc">
<Query>
</Query>
<ReportSections>
</ReportSections>
and the second xml file is named as XMLGenrated,
<Fields>
<Field >
</Field>
</Fields>
and I need the Output as,
<DataSource Name="XXXX">
</DataSource>
<DataSource Name="ABC">
</DataSource>
</DataSources>
<DataSets>
<DataSet Name="abc">
<Query>
<Fields>
<Field >
</Field>
</Fields>
</Query>
<ReportSections>
</ReportSections>
Both the Files are in .XML Extension and I dont know how to find the node by its Name Can anyone help me out.
I tried this,
XElement xFileRoot = XElement.Load(XMLTemplate.xml);
XElement xFileChild = XElement.Load(XMLGenerated.xml);
xFileRoot.Add(xFileChild);
xFileRoot.Save(file1.xml);
but the XML adds below the XMLTemplate I dont know how to insert at particular node.

Find the node using Linq to XML and Replace its contents
XElement xFileRoot = XElement.Load(XMLTemplate.xml);
XElement xFileChild = XElement.Load(XMLGenerated.xml);
var queryNode = xFileRoot.Element("Query");
queryNode.ReplaceWith(xFileChild) ;
Based on on this answer - How can I update/replace an element of an XElement from a string?
Be aware that you sample XML files contain multiple root nodes, and that if you need to keep the <Query> node you need to change this.

SQL Server bulk insert XML format file with Maximum LENGTH

I want to set the length to MAX for one of my XML fields.
XML Code:
<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="1" xsi:type="CharFixed" LENGTH="3" />
<FIELD ID="2" xsi:type="CharFixed" LENGTH="MAXLENGTH" />
<FIELD ID="3" xsi:type="CharFixed" LENGTH="10" />
<FIELD ID="4" xsi:type="CharFixed" LENGTH="8" />
</RECORD>
<ROW>
<COLUMN SOURCE="1" NAME="Field1" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="2" NAME="Field2" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="3" NAME="Field3" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="4" NAME="Field4" xsi:type="SQLNVARCHAR"/>
</ROW>
</BCPFORMAT>
But 'MAXLENGTH' does not seem to work.
Error message:
bad value MAXLENGTH for attribute "LENGTH"
Any suggestions on how to put the LENGTH to maximum ?

The length of a string is limited to 4000 (nchar) or 8000 (char) type. There is no max length-constant - AFAIC
Refer to this, "Field Attributes"
If you look up the schema meta-data just as SQL Server does, you can follow this link
http://schemas.microsoft.com/sqlserver/2004/bulkload/format/bulkloadschema.xsd
to find this
<xsd:attribute name="LENGTH" type="xsd:positiveInteger" use="required"/>
[...]
<xsd:attribute name="MAX_LENGTH" type="xsd:positiveInteger" use="optional"/>
So the length is required while max_length seems to be optional, but if you specify it, it must be a positive integer.

Deserialize with XmlSerializer having external xmlns reference

I have an ever increasing number of BCP (t-sql) format files in XML that I need to read. I create the xsd file using xsd.exe and a number of BCP format files and attempt to read the xml file as an object. But it fails like this:
Unhandled Exception: System.InvalidOperationException: There is an error in XMLdocument (4, 6). ---> System.InvalidOperationException: The specified type was not recognized: name='CharTerm', namespace='http://schemas.microsoft.com/sqlserver/2004/bulkload/format', at .
The XML file is like this:
<?xml version="1.0" encoding="utf-8" ?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="1" xsi:type="CharTerm" TERMINATOR=";" MAX_LENGTH="32"/>
<FIELD ID="2" xsi:type="CharTerm" TERMINATOR=";" MAX_LENGTH="4"/>
<FIELD ID="3" xsi:type="CharTerm" TERMINATOR=";" MAX_LENGTH="4"/>
<FIELD ID="4" xsi:type="CharTerm" TERMINATOR=";" MAX_LENGTH="20"/>
<FIELD ID="5" xsi:type="CharTerm" TERMINATOR="\r\n" MAX_LENGTH="16"/>
</RECORD>
<ROW>
<COLUMN SOURCE="1" NAME="col1" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="2" NAME="col2" xsi:type="SQLINT"/>
<COLUMN SOURCE="3" NAME="col3" xsi:type="SQLINT"/>
<COLUMN SOURCE="4" NAME="col4" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="5" NAME="col5" xsi:type="SQLFLT4"/>
</ROW>
</BCPFORMAT>
I read the XML file like this:
FileStream fs = File.OpenRead(formatFileName);
XmlSerializer serializer = new XmlSerializer(typeof(FormatSchemasXml.BCPFORMAT));
FormatSchemasXml.BCPFORMAT bcp_format = (FormatSchemasXml.BCPFORMAT)serializer.Deserialize(fs);
fs.Close();
The external xmlns reference does not seem to be used. I have searched a lot of documentation, but failed at seeing how I can fix this. Preferably without having to modify the BCP XML format files (I'd like to use them as is).
Suggestions?

Is it possible to Update Sharepoint List Without "ID"?

I want to Upload File on Sharepoint and while apploading only i want to add all properties of Uploaded Document.
We get ID field only when Document is uploaded on Sharepoint.
Is there any other way to Update List without passing ID Field.
Example:
<Batch OnError="Continue" ListVersion="1"
ViewName="270C0508-A54F-4387-8AD0-49686D685EB2">
<Method ID="1" Cmd="Update">
<Field Name="ID">4<Field>
<Field Name="Field_Name">Value</Field>
</Method>
<Method ID="2" Cmd="Update">
<Field Name="ID" >6</Field>
<Field Name="Field_Name">Value</Field>
</Method>
</Batch>
Refering Link
**** I am using Sharepoint Web Services.And Uploading Document in Chunks.****

This is not possible. First the file should complete uploading, then it will have properties that can be set! (otherwise properties may be set for non-existing files, in case that the file fails to upload.)
