I want to upload a file into an document library having flag value. When we do upload a file flag value should be "Zero" and when we click save flag value should be updated as "one"

// First locate your sharepoint site and hit service in browser.
// It is like "http://fullsitename/_vti_bin/lists.asmx"
// If you do not get 404 then it accessible and seems working for current user.
// Add its reference to project.

// SharePoint 2010 provides web service list.asmx which can be used.
// It can be used with Jquery Ajax calls as well.
// In below example i updated listitem by attaching attachment to it.
// Care fully add web reference in project or you will not get ServiceWebReference.Lists class.
// ServiceWebReference can have different name, as you prefer.
// This is working POC...... Hope this help :)

private void button1_Click(object sender, EventArgs e)
{
string srcUrl = @"C:\Users\prasads\Downloads\birthdaypic.gif";

if (!File.Exists(srcUrl))
{
throw new ArgumentException(String.Format("{0} does not exist",
srcUrl), "srcUrl");
}

FileStream fStream = File.OpenRead(srcUrl);
string fileName = fStream.Name.Substring(3);
byte[] contents = new byte[fStream.Length];
fStream.Read(contents, 0, (int)fStream.Length);
fStream.Close();

ServiceWebReference.Lists listService = new ServiceWebReference.Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;

try
{
string addAttach = listService.AddAttachment("mylistname", "1", fileName, contents);

}

catch (System.Web.Services.Protocols.SoapException ex)
{
// catch error
}
}
