[newbie] public static property error - stack overflow

I'm using a static property to pass a shared int value, however, code is breaking when setting the property value.

Any idea why?

Confused | :confused:

public partial class TaskEntry : System.Web.UI.Page
{
...
Global.TaskCategory = 0;
        Response.Redirect("TaskEntry.aspx");
...
}


public class Global
{
    public static int TaskCategory {
        get { return TaskCategory; }
        set { TaskCategory = value; } //breaks here!
    }
}

Error:
An unhandled exception 'system.stackoverflowexception' occurred.

}

a property lets you write code that stores the actual value. Because the value you set, is the property, this code calls itself. If you use a property, you can, in .NEt 3.0, create it without creating a variable to store the actual value, but if you want to write the code, as you have here, you need to create a variable, such as static int _taskCategory. and then set that value in your property.

ASP.NEt cannot play video, anyhow, all you can do, is embed code in the page ( which is just HTML, there's no ASP.NET component involved ) to use media player to play the video. Thingsl ike the time played, also cannot be done in ASP.NET, they need to be done in javascript, if the component supports them.

Hi,

I have nested Iframes.

PageA has Iframe 1

Iframe 1 contains Page B with Iframe 2

Iframe 2 contains Page C.

On Page C ,when a button is clicked . I need to pass few values to Page B and populate the labes there on Page B. In my Java script when I try to get the top.document it always returns Page A.

What javascript code can I use to get hold of my second page (page B) from my third Iframe after a button click on it?

regards

First you need to understand what you can pass using JavaScript and what not

Do
You can only pass string values from
one function to another
one page to another

Don't
You cannot pass any object using JavaScripts

You can save object in session and then access it on another page.

You are passing javascript object to a javascript function.

But you cannot pass a javascript object to ASP.net
and reverse is also not true

That's not correct, you can pass javascript objects in javascript functions. I think you might be getting confused with trying to pass the ASP.net Page object to a javascript function (which indeed, you cannot do).

I mean, you cannot pass objects between javascript and asp.net

but one can pass objects between javascript functions.

You can't do it like that, as you're trying to pass an asp.net object to JS. You can do it like you had it in your reply below:

lnkAddCity.Attributes.Add
("OnClick", "ActivateCountry(this," + lnkAddCity + ")");

session is created in Server Side,
You need to call AJAX request for the session from javascript.

You can access a Session variable in javascript function.Example:

function GetUser()
{
 var user='<%=Session["userid"]%>';
 alert(user);
}

now it shows the current value of Session["userid"].

<%= >
is a ASP server side tag, it will execute the code and will replaced by the result.

The above code you have pasted is a code that is not executed.
View the page in browser and output will be in form

var user='some text';

It's obvious you have no idea what you're doing, perhaps you need to ask a higher level question about what it is that you're trying to achieve.

You can convert any C# to vB.NET using CodeDom namespaces.
Well, but it sometimes fails. bcos of lack of some features between languages.
Otherwise its perfect.
For Quick conversion, you can use

Learn the other language - there really isn't that much difference. If you can't get used to the syntax with a day or so of learning, then there's probably something wrong...

Subin Alex,

I use C#-->VB and VB->C# converters from http://www.tangiblesoftwaresolutions.com; I do not work for them or associated with them in any way.

Your outcome will depend upon your proficiency level in both languages.

I suggest trying their demo versions to get a flavor of what might be in store for you.

At one time I used their demo versions at some clients to 'convert' some classes(and a few projects) that are several thousand lines of code. The demo only allows 100 lines at a time. I was so good at it, it only took 5+ minutes tops.

If anything, these types of converters can help you grasp the original language (or the language to be converted to) that much quicker.

No. Don't rely on them. If you know C# well, what's the big deal in programming VB.NET?
