We usually catch unhandled exceptions in Global.asax, and then we redirect to a nice friendly error page. This is fine for the Live environment, but in our development environment we would like to check if CustomErrors are Off, and if so, just throw the ugly error.
Is there an easy way to check if CustomErrors are Off through code?
Is there a way to check a textbox by using a regular expression without using the <asp:RegularExpressionValidator> ? I have a few buttons on my page, and any onclick is causing the regular expression to execute. I want it to work only for the final submission button. Can I check with C#?

I want to be able to determine programmatically if the System.webServer/Security requestFiltering section exists inside the the web.config file of my application.I am able to do it for other sections like system.web using the code below, but so far no luck with system.WebServer.

Label1.Text = section.MaxRequestLength.ToString();
Here's part of my markup

View 2 RepliesI've just uploaded an asp.net web project to a Fasthosts shared server (yes, I know!). The site works fine on a different server, and builds successfully. However, when I upload it (or even just the files in the App_Code folder) to the fasthosts server, I just get a flat error 500 message.
I've ensured that the web.config file includes: <customErrors mode="Off"/> but still nothing - just Error 500.
The Fasthosts server is running asp.net 3.5, which is what the web project is built to.
add php Extension to IIS6 and IIS 7 via Code in C# using WMi (System.Management). I cant use DirectoryEntry.
I am stuck with adding a new ScriptMap Object to IIS 6/IIS7.
I have read some posts at here and there and heard that adding new WMi object from Scratch is difficult.
I want to enable IIS 6/IIS7 to handle php as well as aspx files and be able to process them. I have extracted php zip archive to a directory on my system (not installed it). The propblem is i am able to modify existing ScriptMap objects but i dont get to understand the add a new ScriptMap Objects.
Also i am not sure whether adding the a new extensiuon handler to ScriptMap will solve the problem or not.
I need to dynamically instantiate a web application from a console application. By this definition, I mean that my console application contains a web application that is not bound to IIS/XSP.Currently, I create the web application into a temporary directory and copy some forged files into it. These are a special Global.asax that maps to my own implementation of HttpApplication to use in the web application (I need to do some initialization at app start), then I forge special .asmx files that map to my own skeleton classes and dynamic plugins
foreach (IPlugin plugin in _target.Plugins)
{
WsdlSkeletonDefinition[] defs = plugin.GetWsdlSkeletons();
My approach works, but I'm not so satisfied by it because I have to write lots of garbage into file system, even if I eventually delete it all.I know I can control HTTP handlers via Web.config, but I don't want to forge a Web.config for that. I would like to create a mapping such as I can remove the .asmx extension from web services' URLs and still get them.For example, one of the default scripts is "LogbusManagement.asmx", which must be hard-coded into client APIs and the .asmx prevents portability to other platforms such as PHP. I want to make "LogbusManagement.asmx" equivalent to "LogbusManagement" and any extension. For this, I might use an HttpHandlerFactory.
My straight question is,like asked here by somebody else: is there a way to programmatically, possibly from Global.asax, to set IHttpHandlers or IHttpHandlerFactories for web applications?
RemoteOnly" defaultRedirect="~/Errors.aspx">
<error statusCode="404" redirect="~/Error.aspx?code=404"/>
</customErrors>
hrow new HttpException(404, "404 Not Found");
Here is my customErrors section:
<customErrors mode="On" defaultRedirect="~/ServerError.aspx">
<error statusCode="403" redirect="~/NotAllowed.aspx" />
<error statusCode="404" redirect="~/404.aspx" />
<error statusCode="500" redirect="~/ServerError.aspx" />
</customErrors>
When an error occurs (I type in a non-existing page in address), I get the default IE "page not found" page.This happens both on localhost in development, and of course in live environment.I think this started happening since a recent Microsoft Update, which included most recent updates to .net.
We developed an application in ASP.NET 3.5 on Windows Server 2003. (IIS 6.0)They are trying to deploy it on Windows Server 2008 IIS 7.5.But we are getting the old yellow screen message: Runtime ErrorDescription:
[Code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
[Code]....
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.Details: To enable the details of this specific error message to be viewable on the local server machine, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off".We have turned off custom errors everywhere we can find in ASP.Net Error Pages and set it to Detailed Errors at all folder levels for IIS Error Pages.Still the yellow screen with custom errors and no detailed errors.If we switch the application pool to run in 32 bit = true, we get a detailed error. But we don't get very far with that because of Oracle issues and wouldn't really want to force it to run in 32 bit when it should really run in 64 bit anyway.So how do we get detailed messages from IIS while running in 64 bit?
I have a folder in my application (UploadsFolder) in which I've been adding images I use for y application. Is it possible to add more images to this folder programmatically online?
View 3 Repliesi am using windows server 2003 and 2008 am about to install a web application on a server that is connected to other computers using simple wired network i.e. no active directory, no domain controller etc..
my question is:
is there a way to prevent mac addresses outside my specified list from accessing my application ? should it be through IIS or Web.config or should i put certain code in the page load events.another concern: if i use an SSL to secure my application, is it enough along with a reputable anti virus to prevent a virus to access my server through any network computer using my web application
I have worked on a timesheet application application in MVC 2 for internal use in our company. Now other small companies have showed interest in the application. I hadn't considered this use of the application, but it got me interested in what it might imply.
I believe I could make it work for several clients by modifying the database (Sql Server accessed by Entity Framework model). But I have read some people advocating multiple databases (one for each client).
Intuitively, this feels like a good idea, since I wouldn't risk having the data of various clients mixed up in the same database (which shouldn't happen of course, but what if it did...). But how would a multiple database solution be implemented specifically?
I.e. with a single database I could just have a client register and all the data needed would be added by the application the same way it is now when there's just one client (my own company).
But with a multiple database solution, how would I create a new database programmatically when a user registers? I have done all database stuff using Linq to Sql, and I am not very familiar with regular SQL programming...
how this could be done (as well as input on whether it is a good idea or if a single database would be better for some reason).
EDIT:
I have also seen discussions about the single database alternative, suggesting that you would then add ClientId to each table... But wouldn't that be hard to maintain in the code? I would have to add "where" conditions to a lot of linq queries I assume... And I assume having a ClientId on each table would mean that each table would have need to have a many to one relationship to the Client table? Wouldn't that be a very complex database structure? As it is right now (without the Client table) I have the following tables (1 -> * designates one to many relationship):
Customer 1 -> * Project 1 -> * Task 1 -> * TimeSegment 1 -> * Employee
Also, Customer has a one to many relationship directly with TimeSegment, for convenience to simplify some queries.
This has worked very well so far. Wouldn't it be possible to simply have a Client table (or UserCompany or whatever one might call it) with a one to many relationship with Customer table? Wouldn't the data integrity be sufficient for the other tables since the rest is handled by the relationships?
In my CMS application, I'm trying to intercept all ASP.NET requests, inspect them and then assign custom HttpHandler if necessary or leave default handling when appropriate.I tried setting HttpContext.Current.Handler in Application_BeginRequest but it doesn't seem to work.There is MapRequestHandler event in HttpApplication but it is not available in the Global application class.
View 1 RepliesI successfully implemented role based authorization in ASP.NET. When a person does not have the needed role he gets to see an error page for 401.2 not authorized.
What I would like to accomplish now is to have a custom 401 page in my application and have it redirected there via settings in the web.config. I tried this:
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="401" redirect="NoAccess.htm" />
</customErrors>
But this does not get caught. Do I have to override it in IIS instead? I hope not as that would make getting things deployed harder.
If I have a customErrors section in my Web.config that says to redirect to Error.html, then putting code in the Application_Error method in the Global.asax to redirect to Error.html is redundant is it not? Technically, I could bypass the Web.config by redirecting to a different page in the Application_Error method if I wanted to, but since I don't want to go to a separate page I don't think I need the code.

View 1 RepliesThe basic idea is we have a test enviroment which mimics Production so customErrors="RemoteOnly". We just built a test harness that runs against the Test enviroment and detects breaks. We would like it to be able to pull back the detailed error. But we don't want to turn customErrors="On" because then it doesn't mimic Production.
I've looked around and thought a lot, and everything I've come up with isn't possible. Am I wrong about any of these points?
We can't turn customErrors on at runtime because when you call configuration.Save() - it writes the web.config to disk and now it's Off for every request.We can't symlink the files into a new top level directory with it's own web.config because we're on windows and subversion on windows doesn't do symlinks.
We can't use URL-Mapping to make an empty folder dir2 with its own web.config and make the files in dir1 appear to be in dir2 - the web.config doesn't apply. We can't copy all the aspx files into dir2 with it's own web.config because none of the links would be consistent and it's a horrible hacky solution.
We can't change customErrors in web.config based on hostname (e.g. add another dns entry to the test server) because it's not possible/supported. We can't do any virtual directory shenanigans to make it work.
If I'm not, is there a way to accomplish what I'm trying to do? Turn on customErrors site-wide under certain circumstances (dns name or even a querystring value)?
By defauly in my web.config I have set the , in runtime I just want to change the Mode = "Off" in memory. I do not want to save the changes to web.config.
Basically we need to see the description of the runtime error, when required.
In my ASP.NET 3.5 Website which is published in shared hosting provider , I've configured my web.config file like this :

<error statusCode="404" redirect="FileNotFound.htm"/>

This is a yellow page which is not user friendly and we didn't expect . I'm wondering setting customeError in webconfig doesn't support this type of address or not ? How can i prevent users seeing this yellow page . Edit : solution you mentioned are about configuring IIS ,But as i mentioned earlier , my site has been published on shared hosting provider . I don't have those access at IIS , What should i do at this situation ?
I have the following settings. Asp.net 2.0 / Vs.net 2005 / Web.config -> customErrors mode="on"
<customErrors mode="On" defaultRedirect="~/ErrorPages/Default.aspx">
My Web.config customErrors section is given below
<customErrors
mode="RemoteOnly"
defaultRedirect="error.htm"></customErrors>
How can I exclude a aspx page from DefaultRedirect, if errors occur in that page?
