Getting The Error : Request Failed
Jan 5, 2009
I 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")

I created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.

I'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"

Request format is unrecognized for URL unexpectedly ending Error I have 3 webservices on windows 2003 server. All worked fine before and are called from one .net application on another server. Recently I added a few new webservice calls, builded and published . All webservices works fine on development locally. On production server all stopped working.
I would like to know how to solve the problem and how to capture the failure of webservice call. The application that is calling those webservices starts new thread to process and shows user Thanks you will get an email. However webservices stopped working and it took couple days to learn that nothing is happening, after research I learned that webservices do not work anymore. Bummer, I do not know how to alert in this case.But first more important how to fix it. On development server in VS 2005 all webservices works perfect. After publishing and testing on server to Invoke a service, the Error ....unexpectedly ending.. appears. After reading many happy postings that modifying Web.config node protocols, I discovered that instead of

So i've coded a simple vb project in MS VB 2008. I then copied the contents of the 'bin/release' folder, and tried running the program on another machine. I'm getting 'the application failed to initialize' error. I'm assuming this is because i'm missing certain files, dll's or something. Or should I have copied the obj/release folder?

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:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>

We have an in-house developed VB.Net Windows Forms application that is losing users' individual connections to the SQL Server 2008 R2 database.The bolded message below is what appears.
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.

For those who still have lots of legacy code as I do in .NET 1.1, has anyone found a solution for this issue[url]...
The directory given in the command line will not exist, which makes sense given the error message. The problematic part is that everything works with a full rebuild. Since the "work around" is so easy, Microsoft of course is not going to fix the problem for .net 1.1.
To everyone who pre-emptively suggests an upgrade to .net 2.0+, that is not an acceptable solution, due to time limits and resources. To those who say that is not an acceptable excuse, go find another thread, not every company is perfect.

At one point however, I get this error which is not an issue when I compile and run the release version.
