ASP.net - Status Code Returned From The Server Was: 500
Jul 31, 2011
First off, I am new to ASP.net, so this is new territory for me.I am using Telerik controls on a VB.net project. I get the following error as a javascript error for every action on the form. Changing any value, whether its a telerik slider, a radio button, asp:button, submit button, telerik rating. Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
I understand that the 500 error is an error thrown when the server doesn't have any more details, however I was hoping someone might have had a similar situation and can point me the right direction as I have a good feeling it has something to do with the Telerik controls.
I was able to submit the form using javascript however then I get the following error, and I don't know if they are related or not.Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
I realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3 Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.
Just finished reading a book on visual basic "Imports System.IO" and "FtpWebRequest". I double checks this code and tripple checked it but I can't seem to find anything wrong with it, bare in mind I did write it from scratch with help from the book so maybe its full of mistakes.[code]
I am writing a small ftp application for a friend and I'm not sure whats going on here. I'll try to be as descriptive as possible. I get a 553 error "The remote server returned an error: (553) File name not allowed." when I try to upload a file.

I added a msgbox to show me what the path to the server is and this is it.Click OK and it gives me the error above.So I changed the "ofd.Files.FileName to ofd.Files.SafeFileName My msgbox now shows this:Then VS throws en error saying it can't find the file in the projects debug folder so I move it there and run the program and it uploads. I noticed that in the first msgbox it has forward and backward slashes could that be my problem or is it something else?
I have an automated program that batch prints PDF files to certain network printers. On occasion our print server will go down & screw up the automated printing process & lose prints. I am looking for a way to check the status of the print server before sending prints. If the status is not "OK" then I want to pause the automated process until the server is back to "normal". Can anyone tell me how I would check this status or where I should be looking?
I've been working on a program that monitors ours and our clients server's to make sure they are still on. the ones that are ping able were easy, now I'm trying to monitor servers that are not ping able. what I'm thinking of doing is creating a small client program to put on each one of the none ping able server that sends a packet to our server every 30 seconds over port 80 (not have to worry about firewalls) and once the server program doesn't receive a packet for 2 minutes then it will display/sound a warning. my questions is is this possible, or is there a better way of doing this. right now i just am checking to make sure the server/internet connection is on, later i will look into getting info from event looks, SNMP, etc.
I attempting to download 6 files from my FTP site to a local server using VB 2008.After 1 or 2 files are downloaded I am geeting an error Bad sequence of commands.It appears the ftp connection is not closing then re-opening.[code]Then I change the file name. After the 2nd or 3rd file, I get the error message.How would I close the connection and reopen it without having to close the program?
I've made this script to read the lines from the txt. But when I try to login I just get this " The remote server returned an error: (530) Not logged in." Even I "logged in" at the link.

I work as an IT Administrator and manage a few Servers, Routers, VPN Connections over a number if locations. What I am wanting to do is create a vb.net app that will go out and ping say every 2-5mins each of the servers, routers, that are listed and then shows beside the Hostname a Green Circle which means online and if its a Red Circle its offline, and the screen refreshes if their is a problem or a device / service comes back online.
Then if its offline email a particular email address showing the hostname of either the server or router and which location saying its offline. If possible to make it easier to change the devices to show possible have a txt file or something like that with the Hostname, IP Address, Location.

I have a form which I use to read data from a text file and export it to an excel template file. The data it reads is constantly updated so I would like to add a check box to cause the data to be read every 10 seconds. It's set up so the user can either do one quick scan by clicking a button, or they can click the button while also having the check box checked and it will scan every 10 seconds.The problem is, once I check the check box, I can't uncheck it. I have created a greatly simplified version of my original code to demonstrate this concept.
I have a asp.net mvc route that is taking a url and doing a simple get and return the status code from the request.
<AcceptVerbs(HttpVerbs.Post)> _ Public Function ValidateUrlStatusCode(ByVal url As String) As ActionResult Dim code As Integer = 0
[Code]....
Now if I use firefox (using Firebug) and go to the url http://www.facebook.com/blah.html, I get the expected 404 returned. However if I use my application to call the mvc route via an ajax call, I get 200. If I set the request object's AllowAutoRedirect to false, I get 302. I never get a 404. I am verifying this once again through Firebug.
