Did you check the link that I have provided to you. On that article I have mention how to create the App_Code Folder. There is nothing to do with ASP.NET Version.
On Solution Explorer > Right Click > Add ASP.NET Folder > App_Code. Thats All Smile | :)

Again, Please check the link that I have provided to you on last post.

Thanks !

Are you talking about variables that every session can access ?

If so then why not you use Application object.

From your code :
Applicatiion["yourvariablename"] = value;

Now this value will be available globally to every session. Call this value using :

object val = Application["yourvariablename"];

It was quite clear that the OP wasn't talking about session or application variables. Abhijit Jana already answered correctly about three hour before you. You should try reading the previous responses and going for quality rather than quantity in your responses.

I think this is wrong.. .

Just see the response next to you, and see actually the user wanted my solution.
We are here to give as many solutions as we can for each posts (so that the base gets enriched and others in future can get reference to it...) rather than to blame each others.

If you see all my responses here in ASP.NET, you will see, I take lots of time to answer each post. I dont post just to increase my post counts.

If you check all my responses, you can see my replies got less no of one liners...

I am not able to create Application variable. I am unable to create appication or session variables. Please help me. I am facing some issues with that.

Abhijit Jana26-Sep-09 23:07

It seems that you are not clear about what you are going to do. I will suggest you to Buy some beginners ASP.NET Books and start reading. This will help you to longer run. As you are confusing with Classes and Session/Application Variable.

Thanks !

You can use the following to create a variable name.

this.Request.Application["name"] = "This is my application";

To get the Name variable use

string s = this.Request.Application["name"].ToString();

If you are outside the page use

HttpContext.Current.Request.Application["name"]

instead.

The error means what it says. You are using virtual paths, and when you change the location, that causes them not to work, because they try to go above the root of the application.

Div creating issues in browser wise

26-Sep-09 0:12

how are you writing an ASP.NET application if you don't understand what I said ? I can't make it any simpler. The error message means what it says. You're using virtual paths, which means when you move the page location, the file path also changes.

I have a div in my master page. The contentplaceholder is inside that div. My need is to display the page without scrolling the page. If the content in my page is heavy then the page will not scroll in the sense my banner and the footer have fix but the content inside the placeholder will scroll. But my problem is when i give a particular height to the div when i enter the full screen mode the footer will shifted to almost middle of the page..

I want to place the content inside that div and i need the scrolling in both full screen and normal screen mode with my footer fixed at the bottom of the page... And i need this property browser wise... Atleast for safari,IE,mozilla,chrome..

Have any solution for this problem... I will copy my design below...

<asp:contentplaceholder id="ContentPlaceHolder1" runat="server">

The class divStyle include the property

.divStyle
{
height: 435px;
overflow: auto;

}

Oopppzz!!!!!!!

Hi to All,

i have 1 problem, i want to implement captcha control in asp.net,i have searched on google also but not found any helpful result.

can anyone tell me how can i use captcha control in login page

Thank you.

Christian Graus25-Sep-09 22:29

25-Sep-09 22:29

captcha is never used in login that I've seen. Certainly the built in controls do not offer that ability. There are commercial CAPTCHA libraries, if you don't want to write your own. You will probably need to roll your own login code, also, and not use the built in stuff.
