How to modify Application level variable
-
I read some [semi] constant values from a file at application start -- File: global.asax.cs --
protected void Application_Start(Object sender, EventArgs e) { Application.Set(Name1, value1); } static public string Name1 { get { return "NAME1"; } }Later, when I need to access the value1, I can do something like:literal1.Text = Application[VSDonation.Global.Name1].ToString();This is all working properly. However, I need to modify the value stored as Application["NAME1"] from an administrative page. I'm having much trouble getting this work. Any pointers or ideas? Thanks. --G -

Thanks. --Gjust an idea... can you take in the value and store it in a non-static variable, then store that in another application variable? You are dealing with a static variable after all.

What kind of trouble? There should be no problem at all to modify the value. The code is exaclty as when you initally set the value.
--- b { font-weight: normal; }

If I create a class to write the value (so it can be used once when the application starts up and again when the administrator changes this value), I get: The type or namespace name 'Application' could not be found (are you missing a using directive or an assembly reference?) in reference to
Application.Set(VSDonation.Global.Name1, sValue); -

My problem is modifying/accessing the Application variable from anything other than the Global class.

My class that was trying to access the Application object was not derived from System.Web.UI.Page. Once I added that to the declaration, I can access the Application space. Thanks. Sorry. --G

That's not really a good way to do it, as your class is not a page. Use HttpContext.Current.Application to access the application object.

Thanks. I've put that in place and it appears to do the trick in a more correct manner. --G
