2.0 -how To Include Files Containing Server-side Code
Oct 20, 2010I want to be able to load a customized log in page depending on a couple of parameters passed into the querystring.Each customized login page needs to be able to dynamically display log in errors and possibly have other variables passed in.
Let's say the dynamic login page looks like this (over-simplification here):
<form>
<% if (has_errors) { Response.Write(error_msg); } %>
<input type="text" name="email">
</form>
If the aspx page loads the file like this:
Response.writefile("path/to/custom/page");
the code shows up in the output and doesn't get processed. I have tried other ways to load the file contents (something similar to classic ASP includes) but get the same results every time.I could have all the custom pages set up as user controls, but I need 100% control over the css, js, and html - and the documentation I read here indicates that I won't have that level of granularity.link textPLUS - I'm stuck in a .net 2.0 environment - so .NET MVC is not available to me

C# - How To Delete Files That Were Uploaded To Server
Aug 31, 2010My system Uploads files to an IIS server and then i manipualate them and after finished doing every thing, i need to delete the original file, the problem is that the IIS "grabs" the file and i can't delete it, when i close the procces i can delete it manualy from the server, but until i close the procces i can't even do that...
I'm using:File.Delete(Server.MapPath(OriginalFileVirtualPath)); to delete the file.
p.s. for now i'm using the .net server, not a full active IIS, but i don't think that the problem is over there...It even make some sence that when i upload a file to the sever, it won't let to delete it strate away, but i'm sure there is a work around...

Web Forms :: Execute Server-side Code From JavaScript?
Jun 11, 2010Executing Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

View 1 RepliesWeb Forms :: Display Cache Data Only Instead Of Server Side Code
Feb 7, 2011I am working on page where data will update in every 10 second by scraping data from other Stock website. So basically page is displaying stock data which update in every 10 seconds. I am using update panel and timer control. Now problem is that if 100 users open the webpage 100 request go server in each 10 seconds. I want to implement Cache on page where Cache version of page serves to other user. I am using <%@ OutputCache Duration="10" VaryByControl="Timer1" %> but when event occur code run intends of delivering Cache version of page. What I am doing for test.
1) Open page in different browser in local
2) Checking browser type using code
Dim s As String = ""
With Request.Browser
s &= "IP = " & HttpContext.Current.Request.UserHostAddress & vbCrLf
s &= "Browser Name = " & .Browser & vbCrLf
End With
Label1.Text = s
if page first open in IE then if I again open in firefox it shows browser type IE but after 10 sec interval it will update type to firefox. So I want to display Cache data only instead of executing server side code for each different browser.

View 3 RepliesWeb Forms :: RadioButtons Executing Server-side Code On Every Postback?
Jun 1, 2010I have a user control with a dozen radion buttons in it.Every pair of radio buttons execute a Sub on server side.All of the radio buttons have the autopostback set to true.There is a public Sub of the usercontrol that gets called only once by the page and loads the data setting the radio buttons to checked or not checked.The problem is, that once a radio button is set, it will execute it's server side code on every postback even if the postback is caused by another control on the usercontrol or even another control on the page. So if all the radiobutton pairs are set and a postback is caused, there will be six server side Sub executing! Casting the sender in each of those Subs gives back the radiobutton that is checked at that point, so it's if on every postback the event is fired for each checked radiobutton.
