C# - File Upload Link Clears When Page Reloads?
Apr 11, 2009
I am using ASP.net(2.0) with VB.NET.
I have a User registration form. On that form the user supply all his contact details and he can upload a image with the normal file upload control in ASP.net.
This is my problem. If anything goes wrong on the page then i give the User a error message saying what he left out or what went wrong. But the page refresh when that does happen. NOW the link to the image the user selected is gone. NOW when the user fix his error he thinks that he is uploading a picture but he never did because when the page re loaded it removed the link to his image inside the file upload control.
Note, the user don't have to upload a image, so there will be no error when the field is blank.

I have a very simple ASP.NET project. It consists of two pages.The first page (FirstPage.htm) has the following markup:
[Code]...
So page one has a hyperlink that loads page two in a popup. Page 2 has a button that should do nothing. However, when I click on the button a new window pops up and loads Page 2 again.
If I navigate directly to page 2, nothing happens.I'm thinking I must have some odd configuration either in VS or in IIS that's causing it; but I have no idea what.

I'm new to using httpwebrequest i've always just used webbrower controls but want to get away from doing that for obvious reason with that said.
I'm having it go to a wepage there is no login what so ever. but there is a cookie that holds saved data from the page. when in IE or any other brower you click an option from a combo box and it reloads the page and saves that data to a cookie.
CODE:
if you just do a httpwebrrquest it goes to 1 - Home what i'm trying to do is get to 25 - Page2 the cookie has the Sid number i'm been searching and reading for atleast 10hrs now and not even close to anywhere farther than i was. if i used Webbrowser it would just save the cookie for me automaticly but want to get away from hearing the clicking and wasting time of downloading all the pictures and stuff.

I'm using the following code to add a table to a user control in Umbraco.
Try
Dim DS As DataSet = GetData()
If DS.Tables(0).Rows.Count > 0 Then

But what happens after the loop completes (without errors - I've stepped through the whole thing), the only content left on the page is the table.

ERROR: Could not find file 'C:Documents and SettingsuserMy DocumentsVisual Studio 2010ProjectsASP.NETuploadASP.NETuploadfile.txt This is not where the file is located. I am fairly new to .NET programming so I may have done some things incorrectly.

How can I refresh my form? I have a button that clears all data from a text file, and the text file is displayed in a secondary tab on my form. When the user views the second tab, they have the option to press the clear button, but I would like the form to refresh so they can see that the data has been cleared. How can I do this?

I use a text file to store the settings from my program.Now when i save the settings the text file gets created and everything works correctly. I can load the settings without any error.Now when i quit my program and star it up again clicking the load button will clear out any data in my text file. So the file still exist but it empty.It happens when my program runs this line of code.
Dim o_read As system.IO.streamReader = system.IO.File.OpenText("C: est.txt")
That just tells o_read that it is a stream reader and which file to read.How does my file get cleared out by that?

I'm trying to add upload controls to the page. This HTML mark-up with JavaScript is working fine but theres no option to remove the added control:
1. Example A
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
[code]....
Every thing was working fine with Example A, only there's no option to remove the added contorls.When I added "Remove" control option with jQuery in Example B, HttpFileCollection can't get any file from input control added to the page.

My office is developing a password-protected based site with thousands of pages. I'd like to be able to send an email to a client directing them to a particular page within the site. Assuming they are not already logged in, what happens is that they are directed to the login page, then, regardless of what link I put in the email, they end up at the default start page after the login.Is there a way that, when clicking on a link to an internal page on a password protected site

I am trying to create a link in a user area of my website. After logging in, the users info is passed to the allow access to specific areas of the site. What I would like to do is create an html link that is controlled by a conditional statement.
for example, after a user logs in, I want to check whether they have credentials to click on a link which will allow them to advance to something new. If they don't have the credentials, the link will be blocked out or not appear at.I am looking for a place to start on this task, any documentation or keywords would be helpful. Also code samples would help greatly.
