Getting The Error : Request Failed
Jan 5, 2009I am writing a program to try and centralise alot of data i have on my network so i can use them as templates and guides. My intension was to have an easy to browse program with links in the program which open the particular file (eg. Word document, excel spreadsheet, pdf file etc).I have very limited programming knowledge and in my research i came across this code in VB which allows the program to open the determined file:
Public Class _010101ProgramTemplate
Dim procstart As New ProcessStartInfo("explorer")
Private Sub btnProgTemp01_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProgTemp01.Click
Dim winDirProgTemp01 As String = System.IO.Path.GetDirectoryName("g:Project Management SystemPMS TemplatesSetupProgramDD-IFC PROGRAM.xls")

View 2 RepliesWsHTTPBinding Over HTTPS Causes Error 400 'Bad Request'
Apr 13, 2012I've been trying to create a simple service to allow messages to be logged onto a remote server via WCF, which all worked fine until I published the service to the live environment, which uses HTTPS.
After some searching, I found that I needed to change my ServiceConfig to account for the different protocol. I used a combination of these two articles:
How to configure WCF services to work through HTTPS without HTTP binding? WCF Bindings needed for HTTPS
Having made the recommended changes to my config, I seem to be in a state where I can add the live service as a WCF reference in VS2010, but when I use IE to browse to the service or the mex address, I'm consistently receiving an 'HTTP 400 Bad Request' error.
In terms of using the service I can seem to run it successfully but the mex just doesn't want to work through IE.
The Service itself is being hosted on Windows Server 2003 R2 Standard Edition SP2 Running IIS 6.0 with no load balancing.
I'm really at a loss at this point, I've spent 3-4 days messing around with this but I can't seem to make any progress.
See below the Server service config in question:
<system.serviceModel>
<services>
<service name="mycorp.Callback.SecPayService"

.net - Error - A Potentially Dangerous Request.Form Value Was Detected From The Client
Feb 4, 2011 why I am getting the following error? I have debugging enabled.Server Error in '/' Application.A potentially dangerous Request.Form value was detected from the client (strContent="<p>test</p>").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (strContent="<p>
test</p>
").
Source Error: The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:

A Transport-level Error Has Occurred When Sending The Request To The Server?

A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)I have looked at many numerous articles both from Microsoft and others, but have been unable to pinpoint the issue.Sometimes it occurs when the user has been away from the open application for a long-time; others maybe less than 20 minutes.

Asp.net - Request() Versus Request.QueryString()?
Jul 5, 2010I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
Intermittent Crystal Reports Error "The Request Could Not Be Submitted For Background Processing."?
Feb 2, 2010We are running Crystal Reports on a Windows Server 2008 with .NET framework 3.5 SP1. I have seen many causes of the general error "The request could not be submitted for background processing." on other forums, however they tend to be persistent and repeatable affecting just a single report due to a specific formatting issue with a specific report.We are seeing this error with the below stack trace, intermittently. It affects multiple different reports we have. It affects one particular report more frequently than other reports. Once a report is affected the same error will often appear in multiple reports at approximately the same time eg. for the next 10 minutes.The same report run with the same parameters may work when run again (soon after) or the application may need restarting before the report can be successfully re run. These reports all worked previously without issue. No change in server or code seems apparent which would have precipitated this error. All code behind for this is VB.NET We have had difficulty reproducing it in test environments and upgrading to the latest version of Crystal has not helped at all.

Visual example from the immediate window:I want to use:

but it won't work because the key is:

View 9 RepliesC# - Get The Host Out Of The Request Object?
Aug 3, 2009I need to get the host out of the Request object. Which property should I use and why?
From MSDN:Uri.DnsSafeHost Property A String that contains the unescaped host part of the URI that is suitable for DNS resolution; or the original unescaped host string, if it is already suitable for resolution.
vs
Uri.Host Property A String that contains the host name. This is usually the DNS host name or IP address of the server.
My testing has been with the ASP.NET Development Server. Both of these always return localhost. Even when I put in 127.0.0.1, both return localhost.Reading on, the DnsSafeHost property will handle IPv6 addresses, as well as Unicode to ASCII conversion if needed. It can also account for IRI and IDN. Even though I currently don't care about these things, should I just use the DnsSafeHost property to be safe?
