Validation of viewstate MAC failed.
A very popular error, so popular and in so many places still unresolved. I spent a while trying to track down what was causing this error on my new hosting environment. I felt it would be a great idea to go ahead and repost my successful solution. I first did a hefty bit of searching on Google of course. Going through dozens of blogs and forums that seemed to all have similar answers for how to solve it. Turn off event validation they would say! Everything I read on that was telling me it would be a security nightmare to have a public application with page validateRequest=”false” enableEventValidation=”false” viewStateEncryptionMode=”never” in your web config file. I tried it anyway and I still got “Validation of viewstate MAC failed.” and I was so frustrated!
I kept searching until I found http://www.developmentnow.com/articles/machinekey_generator.aspx that generated a machine key and the xml required for my web config file. I put that in there an set the page attribute enableViewStateMac to true and uploaded my changes. I waited, 5 minutes no error, 5 hours no error, 24 hours no error. I exclaimed with joy when I could refresh my free online dating search page after being idle a while and not see that terrible error. I hope this helps out someone else as I spent way to long tracking down an answer to this problem.
DiveIntoThePool.com free online dating site launched!
This main page is practically a launch announcement site at this point. It’s been a long hard road to launching DiveIntoThePool.com and I’ve so far met all my goals I set out to when beginning development on the site. It was in a language I’ve never used, ASP.Net in C#. On a platform I didn’t know, Windows and IIS hosting. It gave me more experience in designing database driven applications and I started completely fresh on MSSQL as well. It’s been over a year and a half since I started this and I feel so great having designed, developed, managed and launched this project finally. Now the fun begins. From here on in I’ve got to use everything I know about SEO and marketing techniques to promote my new website as I refuse to let it become dormant as I’ve seen so many dating sites do. I’ve setup a blog for the site as well to talk about things that are specific to that project. You can follow the project on twitter, Facebook or MySpace too! Let me know what you think of the new site or if you create a profile!
Weddingtracker launched!
Posted by sosuke in Flash, Portfolio, Website Analysis on June 14th, 2008
Weddingtracker launched on June 12th around 2:30PM CST and it has been about 8 long months of development and battle to get it out the door. With over 18,000 lines of code, over 400 files and 64mb in size this has been by far my most complicated Flash project ever. You can see the 13 template files in action on the Weddingtracker sample sites page. We did not design the sites so be sure to look past the front-end user interface when continuing through this post. I want to detail some of the finer points of the production and elements that I am happy with.
The entire project was coded using ActionScript 3.0 and the underlying framework that was used was PureMVC for Flash CS3. It was very stable once we got comfortable with working in its rather verbose arena. Each of the components that made up a users website existed in external files. Template layout, page type content, template colors, menu types, custom media display files and embedded font resource files. All of this makes for an extremely extensible code base that will allow for much more complicated designs without endangering the underlining controller code that sets up how the user interacts with the different pages.
All of the colors and text formatting are loaded in from CSS files that are defined in the initial XML file loading process. These CSS classes are accessed by the different page type controllers when they format themselves. Placeholder movieclips are used in the template resource files to define the location and size of the page type elements. The first class in the CSS files defines a list of used embedded font files required for accurate rendering. These font files are loaded from external SWF files and then registered to the Flash application for usage on embedded TextFields. Many of the ideas that made up this runtime font loader came from this post Runtime font loading with AS3 Flash CS3 not Flex.
I think that this code base is a great start to what could be an excellent product with some more attention to the design and user interface components. I expect to be working on it for the next couple of weeks for post launch issues and into the future when new templates are designed. All of the work over the last 8 months will be extremely helpful when it comes to fixing bugs or making improvements in the future.
I wanted to say thank you to everyone who helped code this impressive project and see it through launch. Susannah was with me in development from the very beginning and the project would not have launched without her help. Andres and Hal came in at the end of the project and worked two weekends in a row to get the template css and skin files setup for me while I finished the components and Susannah worked on custom template elements. I am already looking forward to my next major project but needed to reflect on over half a years work and a successful launch. Congratulations to everyone who worked on this project in the .NET development, all the HTML and CSS work and thank you to the IT project manager for being there from beginning to end of the marathon project.
