Cookies without a webserver

I'm working on a clientside app that will use javascript on html pages that are stored in the users local my docs folder. This page is then displayed on the users active desktop. The active desktop refreshes at a set time which is great for my app but I need it to remember some setting each time it refreshes. Cookies is what I thought would be a great idea but I don't think I can use them without a webserver. Any ideas?

In the code behind ? You can't. You have to put a server control inside there, for example, a placeholder or a literal.

If the DIV tag is set to run server-side, it can be referenced in the code-behind as an instance of a HtmlGenericControl class. I'm not sure how the OP intends to populate it though.

Hi,

I am using ASP.NET 2.0. I have a panel control on my page and I want to add a div to it at runtime. How do I do this. I also want to set the class property of the div at runtime accordingly.

Thanks

Put a literal inside the panel, and then set it to be the div, with the class property, in your code behind.

Friends,

My cookies value gets reset between every two or three redirect between pages. The cookie value does not reset in mozilla or some version of IEs.
So the problem is not with the code. I have checked everything in IE options also . Wat might be the problem?

a row? What is that? Table row?

If you want to add the row to the HTML table, you can use Javascript to do that. Please check the link below.

hi,

I am trying to use AJAX for my two dropdown lists for my project using ASP.NET. On selecting an item in one dropdown(say dropdown1), the items for other dropdown(say dropdown2) should populate. Dropdown1 items are retrived from database using C#. My question is I need the selected item value of dropdown1. If I use dropdown1.SelectedItem.Value in C# side means error occurs. I need the selected item value.How can I get it using either javascript or C#.

Just now I am populating all the items in dropdown2. But I need the selected item value of dropdown1, so that I can able to filter and populate items in dropdown2 corresponding to dropdown1 item.

Can anyone help me. Please..........

Why don't you make a search "javascript get selected item of dropdown[^]" in Google first? Smile | :)

this.options[this.selectedIndex].text<br />
this.options[this.selectedIndex].value

Ref: http://www.velocityreviews.com/forums/t120967-dropdownlist-selecteditem-javascript.html[^]

var dropdownIndex = document.getElementById('colorsselect').selectedIndex;<br />
var dropdownValue = document.getElementById('colorsselect')[dropdownIndex].value;<br />
document.write(dropdownValue);

Ref: http://blog.techsaints.com/2007/05/06/javascript-how-to-get-selected-item-in-dropdown-select-list/[^]

Actually, both examples are the same.

Thanks. I have searched in Google first and also posted here. Its working fine.
I found that to get the value we can also use

document.getElementById('<%=ddlTraining.ClientID%>').value;

Its also returning the selected item value.

Thanks for ur help and I need it.

Hi all, I am developing one application. In that i have created on report file which contains tables, titles and tree view list also by using HTML tags. I am opening this file in my application it self as another window.
There is no problem in opening this file if the file is small. If the file is big(here i mean to say, if number of tables present in this file are more)then while opening this file my application is displaying a message "Cannot create unique tag, giving up" (This message is given by HTML script i think) . I am unable to understand this message.
Can any one please tell me how to avoid this ???

Hi guys,

Need some help on this.

There are some image files available on a machine having windows OS installed. My web server is a unix based system. While creating webpage on unix based machine i need those image which are available on window OS based machine.

Is it possible to use those image files without uploading on our unix based machine.

If yes please let me know the process.

Is your Windows OS is the Web server too? Can that windows machine be accessible from the Internet? If the answer for both questions is Yes then it is possible to use those image files without uploading on UNIX-base machine. If No, it's not possible. I think this might be the second time that you are asking this question. I hope my answer might be clear for you. If you still not clear then you reply to this thread instead of posting new post. Thank you.

Allow user to download file that is located at another web server

fukchai200011-Dec-07 14:54

Hi guys,

Need some help on this.
I'm writing a code that will allow user to download a file on a click of button (www.my-website.com).

(#1) one of the way i did was open up a new window with javascript and pass in the URL like:
http://www.other-website.com/myfile.mp3

www.other-website.com is located on another machine & different network from www.my-website.com.

the #1 works fine, the problem is, on some PC, window media player will automatically play the audio rather than download it. Try to use "content-disposition" on header, but have no idea how.

If i want to use a HttpResponse to allow user to download a file is it possible?
(#2) i wrote something like this:

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "audio/mpeg";
HttpContext.Current.Response.AddHeader("content-disposition",String.Format("attachment; filename={0}", filename));
HttpContext.Current.Response.WriteFile("http://www.other-website.com/myfile.mp3"); //throw exception (not recognize virtual path)
HttpContext.Current.Response.End();

so question would be:
1. if i want to use #1, is there away to include the "content-disposition" when open up a new window?
2. is #2 a possible solution? will it actually work?

Best Regards,

Henri

hello everyone,

i'm trying to create an active document activeX for my files. so that they would show up inside the browser after being downloaded (just like PDFs and office files).

i'm trying to use the IOleDocument and IOleDocumentView interfaces to work with IE with c#.

i've created a dll file which import the Microsoft.VisualStudio.OLE.Interop namespace and then two classes that implement the IOleDocument and IOleDocumentView interfaces. i also managed to configure IE to call my dll using a guid.

the problem begins after clicking the file click in IE, and this is the error message i get:

"the file you are downloading cannot be opened by the default program.it is either corrupted or it has an incorrect file type.as a security precaution, it is recommended that you cancel the download"

this is my code:

            }<br />
            pdwStatus = 8;<br />
        }<br />
    }<br />
}

does anybody happens to know how to actually create active documents in C#??
thanks,
Roey

Hi,

Is writing the current time from javascript to a hidden field the only way to get the time of the PC? I am using C#, isn't there a method which can be run?

I want the time to be the moment when the insert/update button is clicked, not when the form loads because the form can be submitted 20 minutes later, or much later.

Thanks
Brendan
