Anybody tried to use the Amazon SQS REST API with .net and ran into the Date header issue? http://developer.amazonwebservices.com/connect/thread.jspa?threadID=18758&tstart=0[^]

How can I get DateTime.now in this format: "Wed, 05 Apr 2006 21:12:00 GMT" ?

/\ |_ E X E GG

Currently, this code will return immediately after the process is started. How can I modify it so that it will not return until the process has stopped? using (Process process = new Process()) { process.StartInfo.FileName = @"C:\myprocess.exe"; process.StartInfo.Arguments = String.Format("-j {0}", path); process.Start(); }

Doesn't XmlIgnore completely ignore the field without any exception?

/\ |_ E X E GG

I have the below campaign class. It is serialized to xml in my code. However, I do not want it to serialize the field if it's set to it's default value. In my case, 0 and 2001-01-01T00:00:00-08:00 for int's and datetime's respectively. How can I have the XmlSerializer ignore them? Is there a global setting for the XmlSerializer class or attributes I can set for each field?

public class campaign : RESTResource
{
    public override String get\_endpoint\_url()
    {
        return campaign.endpoint\_url;
    }

    public static string endpoint\_url = "/campaigns/";

    public int id; //if 0; don't serialize
    public string name;
    public int category\_id; if 0; don't serialize
    public string subject; 
    public string body; 
    public string thumbnail; 
    public string notes; 
    public int ad\_id\_source; //If 0; don't serialize
    public int campaign\_status\_id; //If 0; don't serialize
    public DateTime valid\_after; //if 2001-01-01T00:00:00-08:00, don't serialize
    public int billing\_code; //If 0; don't serialize
    public DateTime created\_at; //if 2001-01-01T00:00:00-08:00, don't serialize
    public DateTime updated\_at; //if 2001-01-01T00:00:00-08:00, don't serialize
}

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)
    {
        //run regex to remove empty Ruby/Rails ActiveRecord nodes for C#/Asp.net compatability
        return System.Text.RegularExpressions.Regex.Replace(p, "<\[^>\]\*><\[^>\]\*>", "");
    }

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.: 0 serilizatoin test 4 i am subject i am body 0001-01-01T00:00:00 4 0001-01-01 0 0001-01-01T00:00:00 0001-01-01T00:00:00 It works find until a field node is empty. For example . 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? -- modified at 19:59 Tuesday 2nd October, 2007 /\ |_ E X E GG

I'm having trouble deserilizing an xml node that has empty tags. See XML: 2007-08-24T16:15:16-07:00 this campaign has alerady been sent 1 4 complete_campaign this campaign is read to send 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...? /\ |_ E X E GG

All I want to do is select all the nodes under the docment root. e.g: 1 2 Traffic Alerts 1 1 News Alerts 1 3 testing category What xpath would return all the Category nodes? But I don't want it to be specific to this xml file. /\ |_ E X E GG

Thanks

I get a compile error on this line: T myClass = new T(); Error 1 Cannot create an instance of the variable type 'T' because it does not have the new() constraint

If Category and any possible other classes have common functionality, then you should go with an abstract base class

Yeah, I have a few other classes... I was just using Category as an example. I'll try out what you've worked out first thing tomorrow. Thanks, Alex

just fixed it.

/\ |_ E X E GG

I have this class structure:

public class Test
{
  public Response Create<T1>()
  {
    string url=//How can I get Category.endpoint\_url here?
  }
}

public class Category
{
    public static string endpoint\_url = "/categories";
    public int id;
    public string name;
    public int content\_provider\_id;

} 

My Category class has a static string endpoint_url. I want to get that string from inside of create using the Type T1 and save it to url. My expected results are to have url set to "/categories"

/\ |_ E X E GG

Thanks. I think I'm going to head in a different direction with this... Now, is this the right use of generics? Category has a static string endpoint_url. I would like to get that from T1 in the Create method.

Create<Category>();
.

public Response Create<T1>()
{
    string url=//How can I get Category.endpoint\_url here?
}

public class Category
{
    public static string endpoint\_url = "/categories";
    public int id;
    public string name;
    public int content\_provider\_id;

}

I guess ruby got my hopes up...

/\ |_ E X E GG

I have a class Categroy that derives from it's base RESTResource.

public class Category : RESTResource
{
}

public class RESTResource
{
public < derived type > Get()
{
}
}

The above example should evaluate to ... public Category Get() ... at runtime. Depending on the Type of the derviced class from RESTResource, how Can I set the return type of RESTResource.Get()?

/\ |_ E X E GG

I have a class Category, that derives from the ServiceResource class.

//Base class for all resources
//Lots of these properties must be overridden by the derived class
//Starting to think it makes more sense for this to be an interface instead...
public class ServiceResource
{

    public string endpoint\_url; //this MUST be over ridden by the derived class
    

    //this takes the object and saves it via API call
    public ServiceResponse Save()
    {
        string post\_params = BuildParameters(); //this should call BuildParameters in the derived class

        ServiceRequest request = new ServiceRequest();

        ServiceResponse resp = request.Send("POST", this.endpoint\_url, post\_params);

        return resp;
    }

    public string BuildParameters()
    {
        throw new Exception("You must set this in the derived class");
        //this MUST overridded by descendent class so this class can make the requests to the API endpoint
    }
}

And the Category class:

public class Category : ServiceResource
{
private int id;
private string name;

        public string BuildParameters()
        {

            return "I am overriding base.BuildParameters()";
        }
        
        //Override base.endpoint\_url
        public string endpoint\_url = "/categories";

        public int Id
        {
            get { return id; }
            set { id = value; }
        }

        public string Name
        {
            get { return name; }
            set { name = value; }
        }
    }

Now I would like to be able to use the Category class like this:

Category c = new Category();
c.Name="new category";
c.Save();

Now when Save is called, it will call the method BuildParameters. However, I want it to call BuildParameters in the derived class and not the base class, same with endpoint_url. At this point, base.BuildParameters is called instead. How can I do this.

How can I have XmlSerializer.Deserializer deserialize an array of Category objects? Right now it'll only work on a single Category object. − 1 2 Traffic Alerts − 1 1 News Alerts − 1 3 testing category − 1 7 curl test − 1 8 sapce test
