I have the book ASP.NET 3.5 WEB SITE. I can't get the view/edit employee to work. (Chapter 10) I have copied the code from the "download chapters" and it still doesn't work. Am I missing something? I don't see where there were typos on this chapter
View 13 RepliesI am trying to download MVC framework but it doesn't work.
View 4 RepliesDue to requirements, I need to open a popup window (javascript window.open(url)) and the url value is an aspx page that downloads a file.
[Code]....
I've tried numerous variations of this code: writing to buffer, Response.WriteFile(), Response.End(), etc...
Nothing works.
All the page does is pop up for about a second and then disappears. I can step thru the code in debugger, but the file never gets downloaded.
I've seen several other posts about this in various places, but no definitive answer.

I am trying to do some code where a user will be able to upload a .JPG picture from the users computer. I have put the controls and also written the C# code wich in my eyes seems to be correct. What happens in the code is that the uploaded picture will replace the existing "TopHeader.JPG" picture.
However when I run the code after I have choosen a .JPG picture from the desktop on my computer. Nothing happens except of a postback of the page.
I wonder what I can be missing out in order to make this work. (I attach both the HTML code and the C# code, I will be happy to know what I could be missing out)

I want to read from database where I've stored a image in binary field and display a image.
while (reader.Read())
{
byte[] imgarr = (byte[])reader["file"];
Stream s = new MemoryStream(imgarr);
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
Graphics g = Graphics.FromImage(image);
g.DrawImage(image, new Point(400, 10));
image.Save(Response.OutputStream, ImageFormat.Jpeg);
g.Dispose();
image.Dispose();
}
con.Close();
This piece of code doesn't work:
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
I migrating a large asp.net webform site to MVC. I want to mix match old asp.net web form and asp.net mvc together for sometime and gradually convert the webform model to pure mvc model.
So i copied all aspx/ascx files from the old webform site to my mvc project. Now when i compile, i get build error. Code behind files can not find any server controls inside their aspx pages.
I can solve this problem by adding a desinger.cs file for each of the aspx,ascx file but that simply is not viable for me since i am dealing with hundreds of aspx pages and user controls and i can not afford to manually add a designer file for each of them.
We have a web service running live. Last week, we pulled the source code down to my machine and successfully built it.
My goal is to become familiar with this code and document it. My problem is that I am not sure how to get it running locally.
First of all, I have to configure it in IIS or something? How do I do that, and is that indeed the right place to begin? I tried creating a consumer in a separate VS solution, and when I said browse for local web services it said "Active Directory Services cannot find the web server."
I tried this link, but got lost when it said "3.Under Visual Studio installed templates, click ASP.NET Web Service." because I don't have that template.
I have a gridview that shows when something is check out. I would like to only show results from todays date and forward. I have done this in Expression Web but when I tried to use the same code in Visual Studios it doesn't work.

In expression web I changed this line from this WHERE [ID] = ?"> to this WHERE [ID] = date()"> and I get the right results.
I often have an issue with compile errors when I copy over a aspx page and code behind file from another project, it seems to work when I create another page and the content manually but if I just copy the files it won't. I have checked to make sure namespaces and references are ok but still doesn't make any sense. The error I get is "Error The name 'txtUser' does not exist in the current context". I just wanted to understand why.
For e.g I copied over the following :
ASPX
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="Login" %>
Login
Login

I am trying to get the modalPopup to work. Don't get any errors, the panel popsup as is supposed to, but the background doesn't gray out and the background of the panel doesn't display correctly either (it is black). The background of the main page doesn't change. To make sure I wasn't doing something wrong, I downloaded the samplcode (vb) from the AJAX website, and created a completely new web page, css file, .vb file, etc. Still have the same issue. I am using the latest version of ajaxcontroltookit ( 4.1.40412.0), VS 2010 RC, and VB)

I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.
I debugged my code and it sets the visible to true and it doesn't show up in view/source either. PnlError is the one not displaying...

I am trying to save an updated xml file to a url like this:
Quote:
//save the output to a file
xmlDoc.Save("http://www.example.com/HomeNewsLinks.xml");
But I get this error: URI formats are not supported.
Did some google search on this and it seems I need to use client.uploadFile method, but I am not able to find how to declare/define filenamexxx (below) and how to pass a username/password.
Quote:
WebClient Client = new WebClient();
Client.UploadFile("http://www.example.com/HomeNewsLinks.xml", Post, filenamexxx);

I am following though the examples in Professional ASP.Net MVC 2 and one of the examples doesn't work for me.
[HttpPost]
public ActionResult Edit (int id, FormCollection collection)
{
Dinner dinner = dinnerRepository.GetDinner(id);
if (TryUpdateModel(dinner))
{
dinnerRepository.Save();
return RedirectToAction("Details", new { id = dinner.DinnerID });
}
return View(new DinnerFormViewModel(dinner));
}
I understand that it's suppose to take the values from the FormCollection, and then update the dinner object with it, bit I don't see the collection get referenced anywhere.
I have div which it is hidden by default , when the use clicks show link the following javascript method is called:
function ChangeControlVisibility(elementID) {
var element = $("#" + elementID);
if (element.css('display') != 'block' && element.css('display') != 'table') {
element.show();
[code]....
this step works but when i call the previous method at page_load event the method doesn't work:
element.css('display') undefined.
