• 12.10 live dvd no video input

  - by mark kirby

  Hi I have been trying install Ubuntu 12.10, but as soon as it gets past my bios and to the screen with the blinking line in the top left, I get a no video input message on my tv (like when you turn the tv on with nothing connected). I have used live dvd's of both betas, alphas and daily build all with exactly the same results. Has any one else had this ? Is there a fix ? Dose this mean I can never upgrade my Ubuntu again ? (12.04 works ive been using since beta) My pc ,while old, should run this fine CPU = 2x Intel P4 HT @ 3ghz GPU = Nvidia Geforce 310 via HDMI RAM = 2 Gb DDR 2 HDD = 2 x 7200 rpm SATA Please help me I use Ubuntu exclusively on my pc and would like to keep doings so.

• Must all new features go through betatest?

  - by LTR

  Obviously, small usability fixes and bugfixes go directly into the stable product. What about small new features? Can you afford to just release them after internal testing, or do they have to be betatested by customers first? Situation: This is a young commercial project, produced by a one-person company. It has an existing userbase and is at it's second major version. Previous betatests have produced some results, however most feedback came from the stable product and not from beta versions.

• How will I know when my company is ready to receive an investment? [migrated]

  - by gunshor

  How will I know when my company is ready to receive an investment? I am starting a company and have bootstrapped it so far. I have produced four versions of the demo. The first fully-working version is underway. Getting this to a beta phase product will require capital, which requires an investment, which requires an investor, which requires I stop working on the product and go out and talk to people about it. The last time I raised money from investors, it took a while but I was successful. I don't want it to take a while. I want it to be brain dead simple for an investor to understand the value so that I can optimize the time I spend with the product. Is my logic flawed? What is the best way to approach raising money, while limiting both my time and risk? Thanks.

• ASP.NET Membership Password Hash -- .NET 3.5 to .NET 4 Upgrade Surprise!

  - by David Hoerster

  I'm in the process of evaluating how my team will upgrade our product from .NET 3.5 SP1 to .NET 4. I expected the upgrade to be pretty smooth with very few, if any, upgrade issues. To my delight, the upgrade wizard said that everything upgraded without a problem. I thought I was home free, until I decided to build and run the application. A big problem was staring me in the face -- I couldn't log on. Our product is using a custom ASP.NET Membership Provider, but essentially it's a modified SqlMembershipProvider with some additional properties. And my login was failing during the OnAuthenticate event handler of my ASP.NET Login control, right where it was calling my provider's ValidateUser method. After a little digging, it turns out that the password hash that the membership provider was using to compare against the stored password hash in the membership database tables was different. I compared the password hash from the .NET 4 code line, and it was a different generated hash than my .NET 3.5 code line. (Tip -- when upgrading, always keep a valid debug copy of your app handy in case you have to step through a lot of code.) So it was a strange situation, but at least I knew what the problem was. Now the question was, "Why was it happening?" Turns out that a breaking change in .NET 4 is that the default hash algorithm changed to SHA256. Hey, that's great -- stronger hashing algorithm. But what do I do with all the hashed passwords in my database that were created using SHA1? Well, you can make two quick changes to your app's web.config and everything will be OK. Basically, you need to override the default HashAlgorithmTypeproperty of your membership provider. Here are the two places to do that: 1. At the beginning of your element, add the following element: <system.web> <machineKey validation="SHA1" /> ... </system.web> 2. On your element under , add the following hashAlgorithmType attribute: <system.web> <membership defaultProvider="myMembership" hashAlgorithmType="SHA1"> ... </system.web> After that, you should be good to go! Hope this helps.

• Repair .NET Framework on Windows 2008 R2

  - by Niels R.

  One of our web servers has become inoperable and after some searching we think the .NET Framework might be corrupted in some way. The server runs Windows 2008 R2 and uses the 2.0 framework for the ASP.NET application that is (or better: was) running using IIS 7.5. I'm wondering how we can reinstall the .NET 2.0 Framework on Windows 2008 R2. Any ideas? Kind regards, Niels R.

• IIS6 Wildcard Mapping to ASP.NET - no file extension results in IIS 404

  - by Ian Robinson

  I'm trying to perform what I understand to be a relatively simple task. I'd like to remove the extensions from the URLs on my website. I have the proper set up in my application to handle and rewrite the URLs - the trouble is I can't get past IIS to actually get to my application without the extensions. The details: I'm running IIS6 on Windows Server 2003. I've gone into the web site for my application, gone to the home directory tab, clicked "Configuration" and added a wildcard map to the following file: c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll Which I verified is the same as what is used above in the application extensions portion by .ascx, etc. If I navigate to http://mywebsite.com/Blogs the result is as follows: HTTP/1.1 404 Not Found Content-Length: 1635 Content-Type: text/html Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET Date: Thu, 14 Jan 2010 15:04:49 GMT Which seems to be a standard IIS 404 message. If I navigate to http://mywebsite.com/Blogs.aspx I get my ASP.NET app.... How can I troubleshoot this? I feel like I've double checked everything a dozen times but to no avail. I must be missing something obvious. Update: Here are the exact instructions given by the asp.net url rewriter that I'm using: IIS 6.0 - Windows 2003 Server open property page for website / virtual directory. click the 'home directory' tab click the 'configuration' button, select the 'mappings' tab click 'insert' next to the 'Wildcard application maps' section browse to the aspnet_isapi.dll (normally at c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll) Ensure that 'check that file exists' is unchecked Click OK, OK, OK to close and apply changes Update 2: I have yet to find a resolution for this. The application does not seem to be receiving the request from IIS, any further ideas?

• Deploy .net 4 via Acrive Directory group policy or WSUS

  - by Terence Johnson

  Is there a way to automatically deploy .net 4 using Active Directory group policy or WSUS? I want to push it out to lots of machines without having to go around to each one. Background: I have a VSTO ClickOnce application I want to deploy to non-admin users, but it uses .net 4, which won't install without admin rights, so ClickOnce fails for non-admins unless .net 4 is already installed.

• When and where to call the RemoveHandler in VB.NET?

  - by marco.ragogna

  I am working to a VB.NET windows forms projet in .NET 1.1. And I have this type of architecture, very simplified. Public MustInherit Class BaseTestLogic Private _TimerPoll As Timer Public Sub New(ByVal sym As SymbolFileMng, ByVal cfg As LampTestConfig, ByVal daas As DaasManager, ByVal mcf As Elux.Wg.Lpd.MCFs.VMCF) AddHandler _TimerPoll.Tick, AddressOf TimerPoll_Tick End Sub End Class Public Class SpecificTestLogic Inherits BaseTestLogic End Class Depending of the type of test I am doing I create an instance of a specific test derived from BaseTestLogic. But I found that after hundreds of object creations I can have StackOverflow exception. I checked my code and saw that I forgot to remove the handler to Timer Tick. The question is, where and when is it correct to remove hadler? Do I need to implement the IDisposable interface in the base class and RemoveHandler in Dispose?

• SQL Server 2008 login problem with ASP.NET application: Failed to open the explicitly specified data

  - by eulerfx

  I am running SQL Server 2008 Express Edition on Windows Server 2008 with an ASP.NET application which must access the server. The ASP.NET application is associated with an application pool that runs on the NetworkService account. This account in turn has a Login and User record on SQL Server in the required database. When I attempt to run the ASP.NET website I get a blank page and when viewed in the error log, I seem to be getting this information event record: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: myLocalMachine] The connection string has Trusted_Connection=True; and the required database specified. When I explicitly specify the user name and password I get another login error stating the password is incorrect, even though the same un/pw combination works through SQL Server Management studio. The NETWORK SERVICE account seems to have all the required privileges for the database. Also, I made a test ASP.NET website project which does a simple select from a table in that database, and using the same config file I am not getting the error and it seems to work. Is it something to do with trust levels then, because the original ASP.NET web app references various DLLs including open source libraries. Also, the application does not seem to be able to write to the event log itself, throwing a security exception, even though everything in the config files, including machine.config states the app is in full trust.

• Unable to launch the ASP.NET Development server because port '1900' is in use.

  - by Shaul

  I don't know what has got into my computer today. I was developing just fine in VS 2008 and testing my ASP.NET web site on my development server. Then suddenly, out of the blue, I can't run my web site any more! As soon as I hit F5, the message appears: Unable to launch the ASP.NET Development server because port '1900' is in use. And it doesn't matter what port I change to, it's always in use! AAARRRGGGHH!!! I have tried: Changing the port number Restarting Visual Studio Rebooting my machine Installing IIS Clue: My IIS refuses to start. But I didn't have IIS installed when I was happily working earlier, so that is probably not the issue; it might just be highlighting something else... Thanks in advance... Update: after rebooting, IIS does start, but the problem here persists.

• How to replace tokens in the master page in asp.net mvc?

  - by AngryHacker

  I have a master page in my asp.net MVC project, which has code like this: <div id="menu"> <ul> <li><a href="#" class="current">home</a></li> <li><a href="#">add image</a></li> <li><a href="#">contact</a></li> </ul> </div> Depending on what page I am on, I'd like to move the class="current" attribute to a different <li>. What is the general pattern that this type of thing is done with on ASP.NET MVC?

• 404 when page exists - IIS 5, ASP.NET 4.0

  - by tsilb

  I have a webserver running Server 2003 Datacenter and IIS 5 which is hosting a variety of ASP.NET 2.0 websites. I'm attempting to add an ASP.NET 4.0 website which I wrote via the VS2010 Beta, and I have .NET 4.0 Beta 1 installed on the server. The website appears to be configured correctly; anonymous access is on, it points to the right folder, and is set to asp.net 4.0. Why might it be giving me a 404 error when I browse to it, both locally and remotely?

• ASP.NET MVC 2 - do UrlParameter.Optional entries have to be at the end of the route?

  - by David M

  I am migrating a site from ASP.NET MVC 1 to ASP.NET MVC 2. At the moment, the site supports the following routes: /{country}/{language}/{controller}/{action} /{country}/{controller}/{action} /{language}/{controller}/{action} /{controller}/{action} The formats for country and language are distinguishable by Regex and have suitable constraints. In MVC 1, I registered each of these as a separate route - for each of around 20 combinations. In MVC 2, I have been trying to get the same thing working with one route to cover all four cases, using UrlParameter.Optional, but I can't seem to get it working - if I define country and language as both optional, then the route /Home/Index for example doesn't successfully match the route. This is what I am trying to do: routes.MapRoute("Default", "{country}/{language}/{controller}/{action}", new { country = UrlParameter.Optional, language = UrlParameter.Optional, controller = "Home", action = "Index" }, new { country = COUNTRY_REGEX, language = LANGUAGE_REGEX }); Is this just impossible because my optionals are at the beginning of the route, or am I just missing something? I can't find any documentation to either tell me what I am doing is impossible or to point me in the right direction.

• How would you audit ASP.NET Membership tables, while recording what user made the changes?

  - by Pete

  Using a trigger-based approach to audit logging, I am recording the history of changes made to tables in the database. The approach I'm using (with a static sql server login) to record which user made the change involves running a stored procedure at the outset of each database connection. The triggers use this username when recording the audit rows. (The triggers are provided by the product OmniAudit.) However, the ASP.NET Membership tables are accessed primarily through the Membership API. I need to pass in the current user's identity when the Membership API opens its database connection. I tried subclassing MembershipProvider but I cannot access the underlying database connection. It seems like this would be a common problem. Does anyone know of any hooks we can access when the ASP.NET Membership makes its database connection?

• IIS 7 + ASP.NET 4

  - by user26712

  Hello, I have an ASP.NET application that I am trying to convert to an ASP.NET 4 application. The application is fairly simple. I have created a new web application in IIS 7.5 pointing to the directory that the ASP.NET application exists in. When I attempt to execute the application, but entering http://localhost%3A%5Bport%5D into my browser, I receive the following error: Error Summary HTTP Error 500.21 - Internal Server Error Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list Most likely causes: * Managed handler is used; however, ASP.NET is not installed or is not installed completely. * There is a typographical error in the configuration for the handler module list.

• How do I setup a Master Page with ASP.net?

  - by Michael

  Hi there, I'm normally a ColdFusion developer, but I'm having to work on a new site using some ASP.net hosting only, so forgive me if my questions seem very trivial. For numerous reasons, the website will be relatively static in the sense that it will mainly be using includes etc...that's about as complex as it will get with this. Now, I heard about the ability to set a master in ASP.net. Would anyone please be able to explain to me in a step process on how to do this? I have of course been searching for some time now on this topic but most results yield little help or no help at all since the search terms are slightly ambiguous. It would be nice to have this functionality for the long run. Any help or advice would be great. Many thanks. Michael.

• Allow Single IP to access ASP.NET Web Service (ASMX) using Firewall

  - by Suresh Agrawal

  I have one asp.net web service (asmx) in separate project that is hosted on windows server having other asp.net web applications running on it. How can I restrict asp.net web service to be accessed by single IP address? I want that my web service must be accessed by one IP configured by me. If requests comes from any other IP, it must not reach to my web service and discarded by windows firewall itself. I know that this is something to do with windows firewall. I did it for SQL Server previously, but I don't know how to configure single asp.net web service project to do so.

• Why does the ASP.Net Web Forms model "suck"?

  - by Daniel Magliola

  I've heard Jeff Atwood, Joel Spolsky, and many other legendary people talk about how the ASP.Net Web Forms model sucks. (So this question is kind of directed to them, hopefully Jeff is reading) Now, I highly respect their opinion, given their background and expertise, but truth be told, I absolutely LOVE ASP.Net. I think the model is brilliant, and it sucks if you have no idea what you're doing, but once you understand how to control ViewState, when to use handlers instead of pages, etc, it is generations ahead of all the other models. So every time I hear someone complain about how it sucks, I can't help ask the same question... Why? What is it that's so bad about it? I appreciate all opinions. I'm assuming there's probably a post at Jeff's blog talking about this too...

• How do I dynamically tell a .NET MVC application which datasource to point to?

  - by Bialecki

  I'm beginning a port of an existing ColdFusion application to .NET MVC and one of the first issues I'm running into is that in ColdFusion we use the fact that you can define multiple datasources and access them in a dynamic way so that a particular user can be pointed at a particular database. To give an example, I might have two databases, Foo and Bar which each have a table called Locations which store locations particular to that database. The databases are guaranteed to have the same tables, so that's not a concern. In ColdFusion, you can easily dynamically point a user towards a particular datasource because it's just a string which is configured via the ColdFusion administrator (or you could programatically modify an XML file). So the question is how to do this in .NET? And specifically, I think I'd really like to use the Entity framework to leverage the ORM support it'll offer to perform operations on the data in the database, but I'm not sure how to do that (hopefully it's possible). Any thoughts?

• IIS/ASP.NET performance incident - Perfmon Current Annonymous Users going through roof but Requests/sec low

  - by Laurence

  Setup: ASP.NET 4.0 website on IIS 6.0 on Win 2003 64 bit, 8xCPUs, 16GB memory, separate SQL 2005 DB server. Had a serious slowdown today with any otherwise fairly well performing ASP.NET site. For a period of a couple of hours all page requests were taking a very long time to be served - e.g. 30-60s compared to usual 2s. The w3wp.exe's CPU and memory usage on the webserver was not much higher than normal. The application pool was not in the middle of recycling (and it hadn't recycled for several hours). Bottlenecks in the database were ruled out - no blocks occurring and query results were being returned quickly. I couldn't make any sense of it and set up the following Perfmon counters: Current Anonymous Users (for site in question) Get requests/sec (ditto) Requests/sec for the ASP.NET application running the site Get requests/sec was averaging 100-150. Requests/sec for ASP.NET was averaging 5-10. However Current Anonymous Users was around 200. And then as I was watching, the Current Anonymous Users began to climb steeply going up to about 500 within a few minutes. All this time Get requests/sec & Requests/sec for ASP.NET was if anything going down. I did a whole load of things (in a panic!) to try to get the site working, like shutting it down, recycling the app pool, and adding another worker process to the pool. I also extended the expiration time for content (in IIS under HTTP Headers) in an attempt to lower the number of requests for static files (there are a lot of images on the site). The site is now back to normal, and the counters are fairly steady and reading (added Current Connections counter): Current Anonymous Users : average 30 Get requests/sec : average 100 Requests/sec for ASP.NET : 5 Current Connections : average 300 I have also observed an inverse relationship between Get requests/sec & Current Anonymous Users. Usually both are fairly steady but there will be short periods when Get requests/sec will go down dramatically and Current Anonymous Users will go up in a perfect mirror image. Then they will flip back to their usual levels. So, my questions are: Thinking of the original performance issue - if w3wp.exe CPU, memory usage were normal and there was no DB bottleneck, what could explain page requests taking 20 times longer to be served than usual? What other counters should I be looking at if this happens again? What explains the inverse relationship between Get requests/sec & Current Anonymous Users? What could explain Current Anonymous Users going from 200 to 500 within a few minutes? Many thanks for any insight into this.

• ASP.NET, PostgreSQL, Mono, Ubuntu, Apache: Good idea?

  - by wreck_of_u

  I am a long-time Microsoft .NET developer. ASP.NET/MSSQL/IIS has been my bread & butter over the past 6 years. Now, I'm getting fond of the "lightweightness" of Ubuntu 10.xx server. I'm also loving SSH-ing it from my Windows 7 PC and installing apps using the awesome "apt-get" command. I've also been using HeidiSQL with MySQL now and loving it. It feels like Management Studio. However, i've read that PostgreSQL "may" be better than MySQL, and I did experience some MySQL overloads in my Moodle box (but this can be just a poor tweaking in my part). My question is, would it be a good idea to run this configuration? ASP.NET 4.0 PostgreSQL (the latest one I can apt-get!) Ubuntu 10.10 with Mono running on Apache Also, I assume I would be using Npgsql for Mono as my connector from ASP.NET to PostgreSQL?
