Re: changing the data type fields using asp.net

What is your question ? I *think* it's 'I took a paid job and have no idea how to do it', but the specifics are lost on me. You have a list of strings, and you have a textbox. Why don't you have a drop down list ? What data field are you changing ? What are you changing it to ? You can't seriously be asking us how to create a drop down list ? Buy an ASP.NET book, and read it. In the meantime, tell your client you lied to them.

touchy touchy. someone thinks they are the master at asp.net coding. i was only asking a general question thought forums were provided to help, and i guess someone has too much time on their hands, coming up with sarky comments to put people down. im actually creating a university project using asp.net coding, i am not getting paid and i have no client to tell them i lied to them. but hey you cant be right all the time better luck next time chum(p)

you should post the actual errror message. However, in this case, it's not hard to see the issue. Buy a basic C# book, and read it. Don't play with things like excel when you have no idea of the basics of C#, it won't help you.

Your error is correct. There is no overload of the Excel method that takes no parameters.

the function written by by needs two parameter, you must pass it in your function call like

Excel(datagrid object,response object)

The miracle is this--the more we share, the more we have.

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.

Thanks again for the reply. Can you post sample code how it be done for the windows application.

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.
