My encounter of Cross Domain for Silverlight 2.0

Today I ran into unusual problem. Today I want to transfer our Beta 0.7 version to testing server which we just recently bought. As it's works perfectly in my developer machine (does this sounds familiar  :p), so i happily transfer my databases and compiled files over to the new server.

Then i realized the URL is pointed as localhost and this works on local machine which I don't intend to test on the machine but over local network. So my past experience with ASP.Net, i can either connect to the newly setup website using IP address (eg. http://localhost/workflow7 to http://192.168.2.10/workflow7). Well it does show me the login page and after I login into, the unexpected happens. As we are developing in Silverlight and about that's about 90% of our current GUI, it stops working and I got this error, crossdomain error calling webservice which we using to communicate our UI layer with application layer. This is really puzzling as I already have the clientaccesspolicy.xml in my application folder. So I start to google about this and seem this is quite a common issue for Silverlight with web services.

Thus I’m really scratching my head and after intense 1 hour of searching, I found no solutions. I have tried crossdomain.xml after found . But still not working but if I switched back to localhost, then everything works again. This is surely frustrated. But after a good dinner and bath, I try my luck again in Google and i found this excellent article about setting cross domain for Silverlight workaround from Jon Galloway article which pointed me to correct direction about my issue. It got me to Tim Heuer blog  about clientaccesspolicy file. I read the whole the article and the last paragraph show my mistakes and it's so plain simple. Let me quote from the site about whereabouts of the file

"Either way, when you are done with the file, it needs to go in the ROOT of the domain.  This is important as it is not the application root, but the root web.  Even if your app is at foo.com/myapp, the policy file needs to be at foo.com/clientaccesspolicy.xml."

Root is the word I’m looking for and my file is located wrong place after all. So it should be at the root of the domain and after i copied the file over to my root domain which in this case is the default (wwwroot folder which i think is default folder used by 90% people  :-D). My application now is working now. I'm so relieve that I don't have to spend another few hours for this problem. So thanks to Jon and Tim for help me to solve my issue. So anyone else is having this issue? Do leave me a comment if you have similar issues and I see if I can help as well.

Have a nice day!

3D Tag Cloud for Blogger

Today i just made some changes in my blog. There's been ages i have updated our blog. As a programmer, i always fascinated with animated programs. So today i made some adjustments to the blog to show a really cool tag clouds. It's combination of flash and some fancy javascripts.

It's a product from WP-Cumulus made by Roy Tanck which meant for WordPress. But there are different implementations for WP-Cumulus and for blogger i found from Amanda Fazani. In her article, we explain how to install BlogCumulus by changing Template and voila we are done! there are some tweaking to it, such as fonts, background color. So for more info, check it out here.

Gold Mindset Workshop

Last week, Veyron and I attended a 1 day workshop. The title of the workshop is "Gold Mindset for Technopreneurs". It was organized by Mdec and Change University.

It started our abit late where i'm late as well. It suppose to be start at 9am and i reach there about 915am.... but luckily i'm not the last, there are couple of people that are late as well. Thus we start about 930am. We started off with some ice break sessions and then our first game 'Blue and Red' game. I'm not going details on the games but i play that before in my Asiaworks course, thus i was relegated to Observer role. But it's pretty good to see those people playing the game and i thought it will be alot of twist but in the end, ethics prevails and one participants points out maybe the stakes of the games is not high enough.

the sharing sessions after the game, i felt dragged abit long and mostly due to trainers really want us to know about what we want to achieve out from the workshop. About 1230pm, we break for lunch. Nothing fancy about the lunch but i had ot with the trainer and we had a good chat about power presentation for senior management like CEO.

we resume our workshop at 130pm and we started off with focus games and how focus enable us to reach our goals. i think the highlights of the afternoon is on the next game we about to play, the speed game. the game is really simple, the goal of the game is achieve the fastest time for all 19 person from the outside of the room and sitted on the chair. the time is counted from everyone come in and last person sit down on the chair. Well first i thought this is going be boring.

the first time we did it, from opening the door , rushing in and scrambling for a chair, all of us took 14 seconds and we thought it's okay. Trainer ask us can we do better than 14 seconds and we say we can. for the next few times, we did from 14 seconds to 8-9 seconds. We did alot of strategies like rearrange the chairs nearer to the door, line our selves up before go in and synchronize our movements and many little things. But our trainer told us that little things only will improves little time as we tried a few times and we still achieved about the same time.

Thus this seriously need a new way of doing it and we did. Most of the time i was the follower, follow whatever other self-elected leaders says. We in the end split ourselves into 2 groups as there are two doors and we achieve 5 seconds. But now trainer told us this is not even bronze timing. And we were like how can this be. We adjust and coordinate better and change some people in two groups. In the end, after i think 20 times of trying, we manage to break the record of 3.58 seconds. We really relieved we made it and break the previous 2 groups record.

i think this help breaks the ice for all of us and we feel we really achieved something that day which we never thought possible. So i think everyone that day learn about change and how learn to change and cope with change can lead us to some better place. We are all champions that day.

We end the day with alot of sharing and from everyone sharing i guess alot of people is learning something and some participants that in the morning seems withdraw or uninterested suddenly by end of the day, all come to life and willing to share their thoughts. Which i can really change and those people has truly "stretched".

As for me, that day i learned something about myself and makes me think alot, deep into what is i want to achieve the days forward. For the past 2 months, we as a group has learn alot and for me is a really eye opener to world of entrepreneurship. But i'm glad i'm part of it now and enjoy the ride and see where this will take us forward. So readers, if you have any interesting stories, let us know. cheers :p
