HttpCOntext is null for windows application

Hi

I am developing an windows application that tries access our handler which calls a provider for the configuration settings. Our Provider cs file contains constructors that access the current httpcontext which is null always, if i access it from my application. My colleague suggested to find a way to instantiate that HttpContext. I googles it but could find any thing. Does anyone here have any idea please!!

Any Ideas would be great!

Thanks in advancs,

Hi,

i'm just guessing but I don't think it is possible to have an HTTP context within an windows application. How do you use the HttpContext? Maybe it is easy to replace this one against sth that is useful within windows apps and web apps.

Hi Sebastian,

Thank you for your reply. I didn't get exactly. The followign code explains clearly how I want to have it in windows applciation.

My dll which access my handler.

private void button1_Click(object sender, EventArgs e)
{
LoadConfigFile(System.Threading.Thread.GetDomain().BaseDirectory);
HttpContext context;
try
{
context = (HttpContext)HttpContext.Current;
}
catch { }
doXtopNotifications.EmailNotifications emailNotifications = new doXtopNotifications.EmailNotifications(this.lastExecutionTime, this.actions, context);
}

EmailNotifications.cs

public GlobalSettings gs;

public void Init(HttpContext ctx)
{
ConfigurationProvider configProvider = new ConfigurationProvider(ctx);
this.gs = configProvider.GlobalSettings;
}

public EmailNotifications(DateTime lastExecTime, XmlNodeList actions, HttpContext ctx)
{
Init(ctx);
}

My Handler class:

public class ConfigurationProvider
{
GlobalSettings _globalSettings = null;
HttpContext context = null;

public ConfigurationProvider()
{
context = HttpContext.Current;
}

public ConfigurationProvider(HttpContext ctx)
{
context = ctx;
}

public GlobalSettings GlobalSettings
{
get
{
//My Code fails in this block of code. I need to get GlobalSettings to access.

if (this.context != null)
{
if (this.context.Application["GlobalSettings"] == null)
loadSettings();
else
_globalSettings = (GlobalSettings)this.context.Application["GlobalSettings"];
}
return _globalSettings;
}
}
}

Well, as I can see it you are using the context to get the "GlobalSettings" from the Application-wide cache (ApplicationState). As a windows app itself does not use the same "session-model" like webapps, you have to load the settings when you want them to access.

I propose a little refactoring of your code. Maybe the "loadSettings"-method should return an instance of "GlobalSettings". If you have an instance of HttpContext, store the settings within the context. This will work for your webapps. If there is no HttpContext you are propably within a windows app, so you don't store them within a context, just return them. (If you like to cache them, just use the singleton-pattern).

Hope this helps you a bit.

1. Change the signature of your loadSettings-method

public GlobalSettings LoadSettings() {
  // load the settings (but don't store them in the context)
  // return loaded settings
}

2. Then change your GlobalSettings-property in ConfigurationProvider

 public GlobalSettings GlobalSettings {
    get {
          GlobalSettings oSettings = null;
          // check for context
          if(this.context != null) {
             // load from context ApplicationState
          } 

          // check if found
          if(oSettings == null) {
             // load
             oSettings = this.LoadSettings();

             // check again for context
             if(this.context != null) {
                // save settings in ApplicationState
             }
          } 

          // return result
          return oSettings;
    }
}

This should work.

There's been some examples posted, even tonight.

You need the client side ids of both controls ( which you get on the server with the ClientID property ). The you use document.getElementById to find both controls. Then you copy the value across.

It means I'd fire someone who wrote that code, but you've got the basic idea, you just need to make it reliable, make it work cleanly, etc.
