Unable To Get Stored Procedure Output Variable Through ExecuteReader

here my code-

using (SqlDataReader sqlDataReader = ExecuteReader(CommandType.StoredProcedure, StoredProcedures.AuthenticateUser, sqlParameter))
{
isAuthenticated = Convert.ToBoolean(sqlParameter[2].Value);
if (isAuthenticated)
{
if (sqlDataReader.Read())
{
User = new UserEntity();
DbHelper.GetEntity(sqlDataReader, User);
}
}
}

I always get isAuthenticated as false because sqlParameter[2].Value is null all the time but when I execute my query with ExecuteNonQuery it gives me the value but in that case I can not fill the entity.

Web Forms :: Browser Output Doesn't Look Like Web Developer Output Using Nested Master Pages And Css Stylesheets

Apr 18, 2010

First off, suggest better ways if you want rather than patch up this code. I am just starting this project and it is first time I have tried to code a web site so anything you suggest is very much welcomed. I have spent the last 2 and 1/2 days trying to find workable answers to this but none I have found and tried seem to fit. If needed I can email screens shots or code. I am trying to construct a website that will have the same main theme throughout as far as the header, navbars sitemap, and footer go. Naturally the content will vary from page to page. I want to use a single master page and css stylesheet for this main theme and I will change the content format as needed per page because each page may vary somewhat.

However, about 15 of the pages will all use the same format for their content and this format will differ from the rest of the site but the format of the main theme will stay the same. So I am trying to create a nested master page to use to format the just the content area for all these pages while retaining the main theme for the header, etc.. I believe I should use a separate css file with the nested master page to handle the formatting of the content areas for these 15 pages. I have code that looks like it works when viewed in web developer but design view but does not work when viewd through a browser (IE, Chrome, Firefox). So far I have the following done in web developer.

If it helps the code and screen shots follow. Master Page called "Parent.master". For all theme throughout site Nested Master Page called "Lab.master". For the 15 like pages Primary stylesheet file for main theme called "StylesheetNew.css" For site theme Secondary stylesheet file to syle the 15 like formatted pages. It is called Labmaster.css Labs.apsx file to use as first of the 15 like pages.
Finally screens shots from web developer and browser. Sorry try as I might I could not capture screenshots and put them into this post. The problem is that web developer shows all the area (many lines high) with gray background and with the XXX text that I want to allocate for content in the 15 pages. Yet all the browser show is one line of text o a white background followed by the footer. It looks like the LabStyleSheet works in Web Developer but not in a browser.

ADO.NET :: Unable To See Option "Copy To Output Directory"

Oct 7, 2010

I am using EF Data model for my database activities and I figured recently that using views were hurting performance of the web application. After some research I decided to pre-generate my view and one of the initial step was to Change the Metadata Artifact Processing property to: Copy to Output Directory. But when I right click on my DB Model designer and check the properties for Metadata Artifact Processing I only see one option and that is "Embed in Output Assembly" I don't know why I don't see the option "Copy to Output Directory". I am Windows 7, 64-bit, VS 2010 Ultimate, .Net Framework 4.0

Web Forms :: How To Get Output HTML And TransmitFile As The Response To An Page

I'm trying to create an ASPX page that displays both an HTML message ("Please wait, your file transfer will begin momentarily") and also commence transmitting a file. I'm trying to avoid making the user open the page, and then clicking a Download buttonIt seems like this may be possible with a "Multipart/mixed" MIME type. Elsewhere I think I read that ASP.NET won't support this.

Unable To Get Login Page Using Master Page To Display Styles With Forms Authentication

Dec 9, 2010

I have seen numerous posts with this problem, however none of the solutions have worked for me. I am using asp.net 4.0 forms authentication. I have the following set in my config file.

<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" />
</authentication>
<authorization>
<deny users="?"/>
</authorization>

The login.aspx page uses a master page and styles in a stylesheet located in a folder off the root directory called 'Styles'. I have also add the following to my config file.

<location path="~/Styles">
<system.web>
<authorization>
<allow users = "*"/>
</authorization>
</system.web>
</location>

When the page displays, the login page displays with the master page content, however all of the styles are missing. When I embed styles into the master page the styles show properly, so I know the problem is that the styles are not being accessed from the file. how I can authorize access to the stylesheet?

How To Output Results In Color To A Web Page

Feb 17, 2011

I am converting an old script from ASP to ASP.NET and would like some advice. The original ASP script used Response.Write to output information about what happened during execution. I have rewritten the entire thing in ASP.NET but it is new to me as an old-school C programmer. The job requirements include using the VB flavor of ASP.NET, btw.

I originally put up a TextBox and edited the text property to dump my final report. Now they want different colors for different message importance and I find that the TextBox can only do one color for all lines. I fell back to the old standby R.W but I get a message that it's not declared and from looking around I see that it's an issue because I'm calling it from the code behind and that is 'out of scope' from the HTML elements of the page itself.

My question is what is the best way to output information to the web page with different lines being different colors from a page's code-behind? Secondary question - if I have misunderstood anything feel free to correct my thinking. :)

Render Page Into Custom Output?

Jan 31, 2011

Letīs take an usual aspx page, ~/admin/template.aspx

The admin folder allows only "Admin" roles for example.

Now I donīt want to run the template.aspx as usual, but I want it be called from a active process. Letīs say Iīm on ~/admin/buildMyStuff.aspx and there Iīm collecting some data, I now have some querystring, like "?do=this$andDo=that$index={0}". Now I want, using this template, loop through my data and generate my ouput, putting it then for example in a static html or in a text file or something else.

How should I do that? Calling it as new request, waiting for response? What I have to do, that it is running under the "Admin" role, or is it doing it automatically, since I already am admin?

Or is there another possibility, that allows me to run the template page and specifiing my custom htmltextwriter as output?

EDIT:

public static string RenderPageAndGetHtml(string pageUrl, string pageQuery)
{
var sw = new StringWriter();
var wr = new SimpleWorkerRequest(pageUrl, pageQuery, sw);

MVC - Enabling Caching Of The Compressed Page Output?

Sep 30, 2010

I've seen a number of options for adding GZIP/DEFLATE compression to ASP.Net MVC output, but they all seem to apply the compression on-the-fly.. thus do not take advange of caching the compressed content.

Any solutions for enabling caching of the compressed page output? Preferably in the code, so that the MVC code can check if the page has changed, and ship out the precompressed cached content if not.

This question really could apply to regular asp.net as well.

Set Page Output Cache VaryByCustom Value Programmatically?

Apr 15, 2010

I want to use an Enum value for the types of VaryByCustom parameters I will support, is it possible to do this?

I tried setting it in the page itself

<%@ OutputCache Duration="600" VaryByParam="none"
VaryByCustom='<%=VaryByCustomType.IsAuthenticated.ToString(); %>' %>

But this returned the entire literal string "<%=VaryByCustomType.IsAuthenticated.ToString(); %>" inside my global.asax is there any way to do this either on the page itself or from the codebehind? Or is this just something I have to accept is purely magic strings and nothing I can do to add type safety to it?

Output Html To Page In Inherited PageBase Class?

Sep 2, 2010

I've inherited (no pun intended) an old ASP.NET 1.1 project that is now .NET 3.5. It is designed with base class that inherits from PageBase. All of the subsequent aspx pages inherit from this custom pagebase. It currently works by generating a bunch of html text in LiteralControls for the headers and navigation bars and dropping it into an HtmlGenericControl (in this case called 'page'), which is then displayed on the page by using this.Controls.Add(page); This actually works, except for the following output:

<span>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
...
</html>
</span>

Those span's aren't supposed to be there obviously, but they come from the HtmlGenericControl, which defaults to a tagName of span. This is causing some strange behavior in IE regarding centering controls on the page.

Basically I know I should be using masterpages for this type of thing, but I don't have time to switch this all over, and I'm not an ASP.NET expert yet to where I know exactly how to solve this problem. Is there another way of sending literal text directly to the HTML output without wrapping it in a control? Obviously I need the DocType to be the first thing on the page; nothing wrapping it.

Render Output To String - Response.Flush Breaking Page Caching

Feb 3, 2010

I have some code that is used to replace certain page output with other text. The way I accomplish this is by setting the Response.Filter to a Stream, Flushing the Response, and then reading that Stream back into a string. From there I can manipulate the string and output the resulting code. You can see the basic code for this over at [URL] However, I noticed that Page Caching no longer works after the first Response.Flush call.

I put together a simple ASP.NET WebApp as an example. I have a Default.aspx with an @OutputCache set for 30 seconds. All this does is output DateTime.Now.ToLongTimeString(). I override Render. If I do a Response.Flush (even after the base.Render) the page does not get cached. This is regardless of any programmatic cacheability that I set. So it seems that Response.Flush completely undermines any page caching in use. Why is this?

extra credit: is there a way to accomplish what I want (render output to a string) that will not result in Page Cache getting bypassed?

ASPX Page:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestCacheVsFlush._Default" %>
<%@ OutputCache Duration="30" VaryByParam="none" %>
<%= DateTime.Now.ToLongTimeString() %>

Code-behind (Page is Cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
Code-behind (Page is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Flush();
}
Code-behind (Page still is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Cache.SetCacheability(HttpCacheability.Server);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(30));
Response.Flush();
}
