c# - How to call/link a workflow on a web application from a c# program?

I have a C# (WinForms) application that can scan documents via a printer. After scanning, I will be able to enter document details on it and have a button to finalize the documents. The documents details and info will be stored in my database ABC in certain tables.
Now, I have another web application written in Java(IntelliJ) that has some button functionality to upload documents and then start a workflow and route it to another user to approve the document. I won't go into detail on the specifics. This application also connects to the same database ABC.
So now comes the tougher part, I need to link these two applications in a way that when I finalize my document
on the C# application, it has to auto trigger the workflow on the web application side. Rather than manually starting the workflow on the web application, it would just call or trigger the workflow, so I do not need to access the web application at all for the process to start.

Is there a way I could call this from the C# application?

You can send your file directly from your C# app with use of Http client. Here is code sample:
private async Task<bool> Upload(string filePath)
{
const string actionUrl = #"http://126.32.3.178:8111/process/taskmanager/start/start.jsp";
var fileName = Path.GetFileName(filePath);
var fileBytes = File.ReadAllBytes(filePath);
var fileContent = new ByteArrayContent(fileBytes);
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(fileContent, fileName);
var response = await client.PostAsync(actionUrl, formData);
return response.IsSuccessStatusCode;
}
}
Also, note that there maybe some sort of authentication should be performed before you can post a request.

reader stopping after first result c#

Ok, so i have written code to make a PDF file using Itextsharp and variables from a select statement. and updates into a database. the reader has to return multiple results with the query that i have made. for some reason it stops after the first result.
can anyone tell me what i need to change to make it iterate through each row that has been returned and update it to the database within in the while loop.
here is my code.

Try to change the order of your statements like given on msdn's example for the MySqlDataReader:
if (reader.HasRows)
{
while (reader.Read())
{
Console.WriteLine("{0}\t{1}", reader.GetInt32(0),
reader.GetString(1));
}
}
else
{
Console.WriteLine("No rows found.");
}
Also check what #Cameron Tinker asked:
Does the query return more than one result if you run it on the
database directly?
And to avoid resource leaks, don't forget to close the reader with reader.Close(); and also the connections. (or better use the using keyword)

c# Retrieve multiple XML child nodes

I've managed to link up a single XElement successfully into my program though I'm not having any luck with the other two I have in place, I've tried using;
IEnumerable query = from booking in doc.Descendants("Booking")

You have several problems:
Firstly, your data elements are not immediate children of the booking element, there are intermediate elements <Customer>, <Holiday> and <TravelInfo>. Thus you need to do something like
var query = from booking in doc.Descendants("Booking")
let customer = booking.Element("Customer")
let holiday = booking.Element("Holiday")
let travelInfo = booking.Element("TravelInfo")
select new
{
//Customer Elements
CustomerId = customer.Element("CustomerId").Value,
Title = customer.Element("Title").Value,
HolidayId = holiday.Element("HolidayId").Value,
TravelInfoId = travelInfo.Element("TravelInfoId").Value,
}
Secondly, several elements are misspelled:
CheckOutTime should be CheckoutTime
In-FlightMeals should be InFlightMeals.
CarHire should be CareHire (yes "CareHire" is what's in the XML.)
Thus, when you do (e.g.) Element("In-FlightMeals").Value, Element() is returning null so you get a null reference exception and your code is aborted.
Thirdly, the element BookTo is completely missing, so BookTo = holiday.Element("BookTo").Value generates a null reference exception.
More generally, I do not recommend this coding approach. If any of your XML elements are missing, your query will throw an exception because element.Element("name") will be null. What's worse, Visual Studio doesn't seem to report an accurate line number on which the null reference occurs, instead giving the line number of the select new statement. And (on my version at least), it's not possible to step into the constructor for an anonymous type either. This makes debugging well-nigh impossible.
Instead, skip the intermediate anonymous type and do things in a more direct, traditional manner:
foreach (var booking in doc.Descendants("Booking"))
{
var customer = booking.Element("Customer");
var holiday = booking.Element("Holiday");
var travelInfo = booking.Element("TravelInfo");
XElement element;
if (customer != null)
{
if ((element = customer.Element("CustomerId")) != null)
txtCustomerId.Text = txtCustomerId.Text + element.Value;
}
// And so on.
}

How do I use lucene.net for searching file content?

I am currently using lucene.net to search the content of files for keyword search. I am able to get the results correctly but I have a scenario where I need to display the keywords found in a particular file.
There are two different files containing "karthik" and "steven", and if I search for "karthik and steven" I am able to get both the files displayed. If I search only for "karthik" and "steven" separately, only the respective files are getting displayed.
When I search for "karthik and steven" simultaneously I get both the files in the result as I am displaying the filename alone, and now I need to display the particular keyword found in that particular file as a record in the listview.
Public bool StartSearch()

bool bResult = false;

Above is the code i am using for search and the xml i am binding to the listview, now i need to tag the particular keywords found in the respective document and display it in the listview as recordsss,simlar to the below listview
No FileName KeyWord(s)Found
1 Test.Doc karthik
2 Test2.Doc steven
i hope u guys undesrtood the question,

This depends on how your documents were indexed. You'll need to extract the original content, pass it through the analyzer to get the indexed tokens, and check which matches the generated query.
Just go with the Highlighter.Net package, part of contrib, which does this and more.

How can I insert an Blank Line using a Open XML SDK class

I want format my .doc file, because when I retrive information and save in a .doc format using Open XML SDK, the document with all information is just in one line, and I need some information in other lines, just to format.
How can I do that?
This is my method that build an .doc
private static void BuildDocument(string fileName, string id, string conteudo)
{
Utilidade.QuebraToken tk2 = new Utilidade.QuebraToken();
////id = id.Remove(id.Length - 1);

"FROM San_Imovel " +
"JOIN San_Filial ON San_Imovel.Filial_Id = San_Filial.Filial_id " +
"JOIN San_ContatoFilial ON San_Filial.Filial_Id = San_ContatoFilial.Filial_Id " +
"WHERE Imovel_Id IN (" + id + ") " +
" AND San_ContatoFilial.TipoContatoFilial_Id = 1";
using (WordprocessingDocument w = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document))
{
MainDocumentPart mp = w.AddMainDocumentPart();
DocumentFormat.OpenXml.Wordprocessing.Document d = new DocumentFormat.OpenXml.Wordprocessing.Document();
Body b = new Body();
DocumentFormat.OpenXml.Wordprocessing.Paragraph p = new DocumentFormat.OpenXml.Wordprocessing.Paragraph();
Run r = new Run();
Text t = new Text();
t.Text = conteudo;
r.Append(t);
p.Append(r);
b.Append(p);
HeaderPart hp = mp.AddNewPart<HeaderPart>();
string headerRelationshipID = mp.GetIdOfPart(hp);
SectionProperties sectPr = new SectionProperties();
HeaderReference headerReference = new HeaderReference();
headerReference.Id = headerRelationshipID;
headerReference.Type = HeaderFooterValues.Default;
sectPr.Append(headerReference);

d.Append(b);
hp.Header = BuildHeader(hp, "Anuncio");
hp.Header.Save();

You can simply create a run with a break object in it and insert this run in your code everytime a page break is required, please see below for an example:
using (WordprocessingDocument package = WordprocessingDocument.Create("D:\\LineBreaks.docx", WordprocessingDocumentType.Document))
{
package.AddMainDocumentPart();
Run run1 = new Run();
Text text1 = new Text("The quick brown fox");
run1.Append(text1);
Run lineBreak = new Run(new Break());
Run run2 = new Run();
Text text2 = new Text("jumps over a lazy dog");
run2.Append(text2);
Paragraph paragraph = new Paragraph();
paragraph.Append(new OpenXmlElement[] { run1, lineBreak, run2 });
Body body = new Body();
body.Append(paragraph);
package.MainDocumentPart.Document = new Document(new Body(body));
}
