Hello:
I have here a problem where I am using web services.
From this example you can see that webservices is very tolerant of extra fields or missing fields. One issue though is that if you run one of the webservices and then update the other project's web reference it generates partial class code for your remote object in the namespace of the webservice. This is a problem.
For instance:
If you run the solution Version1 and then open the solution
Version2 and update the Web Reference in the project (you have to show hidden files) you get a file called Reference.cs.
In Reference.cs the system generates a wrapper for the class Foo
/// <remarks>
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml","2.0.50727.1378")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")]
public partial class Foo {...}
The problem is that when it does this it will return this object as when you call HelloWorld.
static void Main(string[] args)
{
ConsoleApplication1.localhost.Service1 s1 = new Service1();
MyLibrary.Foo f1 = new MyLibrary.Foo();
f1.Prop1 = "New";
MyLibrary.Foo f2 = (MyLibrary.Foo)s1.HelloWorld( f1);
System.Console.WriteLine("F1.Prop1=" + f2.Prop1);
}
Which is not what you want. The intended object is MyLibrary.Foo not ConsoleApplication1.localhost.Foo. Please figure out how prevent VS from creating the wrapper or any other solution.
Below are the project codes:
"Version1" Solution:
Webservices:
using System;
using System.Data;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.ComponentModel;
using System.Xml;
using System.Xml.Serialization;
using MyLibrary.Lib;
namespace Version1
{
///
/// Summary description for Service1
///
[WebService(Namespace = "http://localhost/")]
[ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{
[WebMethod(EnableSession = true)]
[XmlInclude(typeof(Foo))]
public MyLibrary.Lib.FooHelloWorld(MyLibrary.Lib.Foo foo1)
{
foo1 = "Updated";
return foo1;
}
}
}
"MyLibrary.cs"
using System;
using System.Data;
using System.Configuration;
using System.Xml;
using System.Xml.Serialization;
namespace MyLibrary
{
public class Foo
{
private string m_prop1 = null;
public string Prop1
{
get { return m_prop1; }
set { m_prop1 = value; }
}
private string m_prop2 = null;
public string Prop2
{
get { return m_prop2; }
set { m_prop2 = value; }
}
public Foo()
{
m_prop1 = "abc";
m_prop2 = "cde";
}
}
}
Console application: "Program.cs"
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using MyLibrary.Lib;
namespace ConsoleApplication1
{
static void Main(string[] args)
{
ConsoleApplication1.localhost.Service1 s1 = new Service1();
MyLibrary.Foo f1 = new MyLibrary.Foo();
f1.Prop1 = "New";
MyLibrary.Foo f2 = (MyLibrary.Foo)s1.HelloWorld( f1);
System.Console.WriteLine("F1.Prop1=" + f2.Prop1);
}
}
*** NOte *** localhost is the name of the web services when i add reference.
If you can provide solution in this Version1 solution it will work also on Version2 solution.
Hope anyone can save me from hell... Thanks

How to make a random number generate? And also, every time it is called, will it generate a new random number? (between 1 and 20, please). Thanks in advance.
|
|
|
|
|
|
It will do what you tell it to.
When I use a Random I prefer to make one static instance that I use throughout the program.
private static readonly System.Random randy = new System.Random() ;
To get a random number in the range 1 -- 20:
int x = randy.Next ( 20 ) + 1 ;

Every day, you post questions that show you have no resources on C#, and are scared to use google. We love to help, but you're never going to learn to code unless you learn how to do basic research, and invest in at least one good book.

Trust me, I do invest in books, but it's not the same as a person telling you directly and so on, not that the site is the same either... The books are things that can't explain it to you if you don't understand what it says, though they usually do help.

Then use that book, to whack yourself on the head if for nothing else.

Well, I taught myself entirely from books, so my advice would be to grab a more basic book to start with. I sure did.
Contrary to what you may think, people here are not trying to take a shot at you, but it is frustrating to see so many people ask the most trivial questions, over and over, it really does make us wonder if anyone does any research at all. We want to help you, I'm giving you advice that I think is the best help I can offer.

Listen to what Christian has to say. He made it to MVP and started out by reading a couple of books. He's living proof that books do work.

The point they are trying to make is that if you goto Google and type "C# random", then you will quickly find what you need. In fact the first 5 (atleast) links explain how to generate a random number in C#.
The answers on those links may not be a quick and short C# snippet that you can directly cut and paste into your code. But I would expect any developer to research it, try some solutions, then if they can't get it to work then ask a question.
A large portion of doing software development is being able to do research, which includes searching the Internet and writing test code (that may never work and may get throw away).
Take care,
Tom

I am not very proficient with VB6, but I am writing an ActiveX EXE for a legacy program to use.
I have code that receives data from the legacy software just fine (I can display it in a msgbox), but need an idea to push that data to a C# event to run some code based on the data.
I know how to hook into the ActiveX from C#, but am having trouble with the C# program recognizing that data is coming.
any help is appreciated and examples greatly appreciated.

You can try with pass or return data the type of object not specific data type (int, string etc).

what is the difference between int? and int
seema
|
|
|
|
|
The question mark denotes it is a nullable value. For example,
int? i = null;
is the same as
Nullable<int> i = null;
The Nullable<T> type wraps a value type, like integers, but allows you to assign null to them. Without this, you couldn't assign null to an int or any other value type.
|
|
|
|
|
int? is shorthand for INullable<int>
A nullable type can be null as well as the normal values and has a HasValue property. Very useful, for example, if you have a numeric column in your database which can be null, or just in general to avoid having to have magic numbers to indicate that no value has been set.

Hi there, i want to know how to setup to nhibernate for use the SysCache2 in my AspNet 2.0 Application... this is what i have been doing, in the web.config:
<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
</configSections>
<hibernate-configuration>
<session-factory xmlns="urn:nhibernate-configuration-2.2">
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="connection.connection_string">server=XXXX;database=XXXX;uid=XXXX;password=XXXX;Max Pool Size=100;Enlist=False</property>
<property name="cache.use_query_cache">true</property>
<property name="cache.use_second_level_cache">true</property>
<property name="cache.provider_class">NHibernate.Caches.SysCache2.SysCacheProvider,NHibernate.Caches.SysCache2</property>
<mapping assembly="Model" />
</session-factory>
</hibernate-configuration>
And in my class i do the following:
public static IList<Country> GetCountryList()
{
string sql = "from Model.Country c Order By c.Countryid";
IQuery query = Base.Session().CreateQuery(sql);
query.SetCacheable(true).SetCacheRegion("nhibernate.country.countrylist");
IDictionaryEnumerator e = HttpContext.Current.Cache.GetEnumerator();
while (e.MoveNext())
{
//The first time nothing happen here
//After that the System.Web.HttpContext.Current.Cache.Count is 2
//How can i get the cached collection??
object o = e.Current;
object k = e.Key;
object v = e.Value;
}
return query.List<Country>();
}
Any help would be appreciated.
Bye.
p.d:oops, its the c# forum, my code was in vb net, now is in the right language

I'm having trouble deserilizing an xml node that has empty tags. See
XML:
<ContentCampaign>
<ad_id_source type="integer"></ad_id_source>
<billing_code type="integer"></billing_code>
<birth type="datetime">2007-08-24T16:15:16-07:00</birth>
<body>this campaign has alerady been sent</body>
<category_id type="integer">1</category_id>
<created_at type="datetime"></created_at>
<id type="integer">4</id>
<name>complete_campaign</name>
<notes></notes>
<subject>this campaign is read to send</subject>
<thumbnail></thumbnail>
<updated_at type="datetime"></updated_at>
<valid_after type="datetime"></valid_after>
</ContentCampaign>
This XML is generated from a rails web service and respresents a table
in the database.
When I try to deserilize this the deserlizer fails on the empty tags.
How can I make the deserializer simply ignore these tags as they have
no value anyways...?

Check out this[^] for elements and this[^] for attributes. Basically, you are going to read them in, but you can trash them later.
Or you could use this[^] to ignore those elements/attributes.

Sorry, But I'm a little overwhelmed. Maybe you can help me more if I'm more specific.
I have this XML that I'm trying to serilize into a ContentCampaign obj.:
<ContentCampaign xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<id>0</id>
<name>serilizatoin test</name>
<category_id>4</category_id>
<subject>i am subject</subject>
<body>i am body</body>
<birth>0001-01-01T00:00:00</birth>
<ad_id_source>4</ad_id_source>
<valid_after>0001-01-01</valid_after>
<billing_code>0</billing_code>
<created_at>0001-01-01T00:00:00</created_at>
<updated_at>0001-01-01T00:00:00</updated_at>
<notes></notes>
</ContentCampaign>
It works find until a field node is empty. For example <code><ad_id_source></ad_id_source></code>. This xml is generated from a database table and when a value is null it simple generates an empty xml node.
The problem with the empty ad_id_source node is tha now, when the deserializer runs, it throws an exception.
Simply, is there a way for the deserializer to ignore these empty nodes?
I noticed that if a node that maps to a string is empty is just defaults to null. Can I configure the deserilizer to set any empty nodes respective type to it's default value? eg. 0 for int, 0001-01-01 for DateTimes?

I'm sorry, I misunderstand what you wanted. I though you had extraneous elements (e.g. items without a matching property in your C# class) that you wanted to skip.
You could derive your own class from XmlTextReader[^]and override the Read[^] method. But that would get messy because you have to take into account elements that only have sub-elements.
The easiest way is to probably define another property that you use for serialization like so:
private Int32 myInt = 0;
[XmlIgnore]
public Int32 MyInt {
get {
return this.myInt;
}
set {
this.myInt = value;
}
}
[XmlElement("MyInt")]
public String MyIntSerialize {
get {
return this.MyInt.ToString();
}
set {
Int32 newValue = 42;
if (!String.IsNullOrEmpty(value))
newValue = Int32.Parse(value);
this.myInt = newValue;
}
}
This gets messy also because you have to double up on your properties.
Take care,
Tom

Hi,
I've just decided to impliment a support layer that removes empty nodes. This is working now and I haven't found any issues with it:
string ct = this.HttpWebResponse.Headers["Content-Type"];
if (ct.Contains("application/xml"))
this.response_text = FilterOutEmptyNodes(this.response_text);
}
private string FilterOutEmptyNodes(string p)
{
return System.Text.RegularExpressions.Regex.Replace(p, "<[^>]*><[^>]*>", "");
}
