While working on our upcoming DotNetNuke Module Silverlight Video Library we came across an interesting thing where you would upload an image (replacing the image on the server if it existed already). This works well until we discovered Silverlight was caching the downloaded images.
Uploading and replacing an image on the server did nothing as the original jpg was cached. A simple command on the bitmap object allows us to get around and effectively bypass the cached image:
bitmap.CreateOptions = BitmapCreateOptions.IgnoreImageCache;
Download this DotNetNuke module from our website at: http://interactivewebs.com and stay tuned for our new release.
While working in Expression Blend 3 we found on one of our work computers we could not run the project from blend.
We were on a Windows Vista and later Windows 7 box, and found that running the project would just return a message like: “Page cannot be displayed” or similar.
Research showed that this was cause by the little application that hosts the local website that runs the project being blocked by an update to Window Defender and Forefront Security. This update mad a modification to the “hosts” file.
Open this file: C:\Windows\System32\drivers\etc\hosts in Notepad, and add the following entry:
127.0.0.1 localhost
Making it look something like this:
A subsequent signature update to both Windows Defender and and Forefront Client Security, released on the same day as the earlier update, should not cause this problem. Gotta love that!

Purpose & Scope
Microsoft® SilverlightTM is a cross-browser, cross-platform plug-in for delivering the next generation of .NET based media experiences and rich interactive applications for the Web. Silverlight offers a flexible programming model that supports AJAX, VB, C#, Python, and Ruby, and integrates with existing Web applications. Silverlight supports fast, cost-effective delivery of high-quality video to all major browsers running on the Mac OS or Windows.
In most cases, hosters do not need to perform particular deployments to support Silverlight. However, check for the following basic items that could prevent Silverlight from functioning correctly.
Procedure
All MIME types needed to support Silverlight are implemented by default in Windows Server 2008 IIS 7.0 and Windows Vista SP1. Windows Vista RTM customers can add mime types by running ‘IIS Manager’, clicking on ‘Mime Types’, then clicking ‘add’ and adding the following mime types:
Alternatively, you can add the following mime types to your %windir%\system32\inetsrv\config\applicationHost.config file in the <staticContent> section.
<mimeMap fileExtension=’.xaml’ mimeType=’application/xaml+xml’ /> <mimeMap fileExtension=’.xap’ mimeType=’application/x-silverlight-app’ /> <mimeMap fileExtension=’.xbap’ mimeType=’application/x-ms-xbap’ />
To enable IIS 6.0 in Windows Server 2003 or IIS7 in Windows Vista RTM with the appropriate MIME Types, add:
Here is a VBS script you could run to enable each of these types:
Const ADS_PROPERTY_UPDATE = 2 ‘ if WScript.Arguments.Count < 2 then WScript.Echo ‘Usage: ‘ + WScript.ScriptName + ‘ extension mimetype’ WScript.Quit end if ‘ ‘Get the mimemap object. Set MimeMapObj = GetObject(‘IIS://LocalHost/MimeMap’) ‘ ‘Get the mappings from the MimeMap property. aMimeMap = MimeMapObj.GetEx(‘MimeMap’) ‘ ‘ Add a new mapping. i = UBound(aMimeMap) + 1 Redim Preserve aMimeMap(i) Set aMimeMap(i) = CreateObject(‘MimeMap’) aMimeMap(i).Extension = WScript.Arguments(0) aMimeMap(i).MimeType = WScript.Arguments(1) MimeMapObj.PutEx ADS_PROPERTY_UPDATE, ‘MimeMap’, aMimeMap MimeMapObj.SetInfo ‘ WScript.Echo ‘MimeMap successfully added: ‘ WScript.Echo ‘ Extension: ‘ + WScript.Arguments(0) WScript.Echo ‘ Type: ‘ + WScript.Arguments(1)
If you copy and paste the code above into a VBS file and save it as ADDMIMETYPE.VBS the syntax to add each type would be:
ADDMIMETYPE.VBS .xap application/x-silverlight-app ADDMIMETYPE.VBS .xaml application/xaml+xmlADDMIMETYPE.VBS .xbap application/x-ms-xbap
1. Go to Start\Administrative Tools and run IIS Manager, see figure below:
2. Right click on the server name and select ‘Properties’, see figure below:
3. In the Properties Dialog, click on the ‘MIME Types’ button, see figure below:
4. In the ‘MIME Types’ Dialog, click the ‘New’ button, see figure below:
5. In the ‘MIME Type’ Dialog enter one MIME Type at the time:
see figure below:

We have often receive lots of questions about Web-safe fonts, or web friendly fonts. We have products that work with technologies like Microsoft Word, and publish back to websites like DotNetNuke. (DNN Word Editor)
The issue is that not all fonts will work on all browsers on all computers. Here is the reason why.
There are an awful lot of fonts in the world! For years, no doubt, you’ve been using a ton of them in word processing documents, party invitations, banners, etc. But have you ever noticed how few of them are used on the web?
There’s a really good reason for this. When a web page loads, the browser is told to write text onto the screen using a specified font—one that is stored on the computer that the browser is running on. Therefore, if the web page’s code is calling for a font that a user does not have installed on their computer, it won’t show up! What that person will instead see is a default font, which might look a little ugly.
Now you might be wondering why this will happen so often if there are so many fonts installed on your computer. Well, here’s the problem: the two most widely-used operating systems—Windows and Mac OS X—each come installed with a different set of fonts. Awesome!
To illustrate this point, here’s where the fonts are stored in Windows 7:
And here’s where they’re stored on Mac OS 10.6:
Right away, we can see that only one of the displayed fonts overlaps: Arial. None of the Calibri orCambria fonts are available on the Mac, and the Mac has at least a dozen just on this page that aren’t available in Windows!
In fact, between these two systems, there are only ten fonts that overlap:
Those fonts that fall into that middle area, covered by both operating systems, are what we callweb-safe fonts. If you use Calibri on your webpage, Mac users won’t see it; if you use Andale, Windows users won’t see it; but if you use Georgia, you can rest assured that users of both systems will see the it.
Now there’s a bit of grey area here. Users of older operating systems don’t have some of these fonts we’ve declared web-safe. For example, Windows XP users don’t have Palatino or Trebuchet MS. Even worse, users of Android mobile phones don’t have any of these fonts.
So to be clear, there are only five fonts that are considered universal:
Feel free to use these fonts all you want! Even if you dug up that old Packard Bell you had back in 1997 and it didn’t explode when connected to the modern web, you’d be able to see these fonts rendered as intended. Those Android users will just have to fight for themselves.
Your text will still be visible, but the browser will use whatever default font it supplies for situations like this. This means that you may have intended to use a cute, scripty font, but what you get is
Your text typed in a regular serif font.
This is good because your content still goes through, but your design might be compromised. Therefore, you should always specify fallback fonts and a category that the font falls into. Let’s say that you want to use Helvetica, but you’ll settle for Arial. Since both of these fonts are considered to be sans-serif fonts, you can write a CSS declaration like this:
{ font-family: Helvetica, Arial, sans-serif; }
The browser will first try to use Helvetica, and if it’s not installed, it’ll attempt to use Arial. If even that font is not available, it’ll use whatever default sans-serif font the browser likes, but at least it’ll be the correct type of font!
For more information about coding fallbacks, alternative methods to using non-web-safe fonts, and everything typography related, you can pick up a copy of our Web Typography Handbook. It’ll tell you everything you need to know.
Today we announced that our DotNetNuke Module for syncing to outlook was updated to DNN 6. Check out the details here.

I noticed a question today on a Microsoft Dynamics CRM discussion site asking
“is there anyone who is not trying to sell me their product, that has done something interesting with CRM and Silverlight?”
Well yes there is…
InteractiveWebs have done several interesting projects with Silverlight as an interface to Microsoft CRM.
One of the most interesting of these is a Silverlight membership login system for a grain trading company based in Australia. The business is an organisation that trades produce in a similar way to how shares are traded in the stock market. The difference being that the commodity being traded has been grown by “growers” (farmers) and represents the produce that their farm has for sale in the open grain trade market.
Interestingly, Microsoft CRM is being used entirely for the backend management of this trading. This is quite complex in it’s design as you can imagine would be the case if you were running a stock exchange using CRM.
Entities are being used to track the bidding for sales and purchasing of hundreds of different qualities of different grains, at different locations over an entire country.
Of note to the Silverlight interface, is the fact that there are an ever increasing number of records within this system in the order of 65,000,000 records of some CRM Entities.
In it’s simplest function, the Silverlight interface is a membership system.
Allowing users to login and manage the buying and selling of commodities. Very similar to how users of a Stockbroking system would login and buy and sell their shares. But of course the user data is all being driven from a CRM backend running CRM 2011 with IFD.
The membership login is using custom attributes within CRM Contacts to authenticate and allow login.
Once logged in the user can modify personal details that are saved back to the CRM Contact entity.
Data is retrieved live using XRM to interface with CRM on the fly. Silverlight gives a clean and robust interface for users.
Just like with the sale of share, there is some paperwork generated with the buying and selling of commodities. Broker Notes, Freight Invoices, and Monthly trade Statements are example of just a few. Originally the thought was to interface with a Microsoft SharePoint server to store the related .PDF documents generated for these items. Instead we took the simpler approach of attaching the .PDF documents to the relevant records in the custom entities that are used to track each trade.
This data is simply stored as CRM Notes with Attached Files (.pdf) to the custom Entities.
Then in the Silverlight interface we allow users to open (on the fly) these notes and attached .pdf files to view the “paperwork” associated with each sale.
Summary data is presented that is referencing custom attribute data, and able to be exported live from Silverlight to Excel.
Or clicking on the PDF icon, will open the associated attached note from CRM and open the .pdf record live.
Example of PDF data.
Growers of commodities can create new stock records, listing the gran they have, quality, quantity, location etc in a simple user interface.
Listing too the price they wish to achieve in order to sell the produce.
Doing this creates a new record in a custom Entity in CRM directly, and this data is used in the bidding and selling process.
The data is available to Silverlight users in their record of stock.
Similar in concept to a statement of shares for a stock market trader.
So far, these are reasonably simple interfaces using XRM to CRM. Reading, writing, opening attached files etc. Where it gets interesting is in some real time graphing that we do to show bids on stocks / commodities.
For this we are needing to access tens of thousands of records that represent different bids for different commodities and work out on the fly the best or highest bid, and show that to the client in a fast loading graph.
This is where Silverlight and some cleaver XRM calls to some cleaver processes in CRM delivers a great result.
With the great graphing tools in Silverlight, the graph draws in real time and animates the loading of data. It has a full screen mode:
And is really a great use of Silverlight for this particular task.
One of the features we built on this interface is the ability to “Run Out of Browser”. So the client can right click the interface and select to “Install to this computer”.
This adds the project to an Out of Browser Silverlight experience that can be launched as any other application or program from your computer.
This feature of Silverlight can run on a Mac or PC, and delivers an experience for end users that is very similar to having a membership program installed on your computer.
The project will auto update if we modify the web based source version with a new release automatically. The client is promoted with a messaging saying the program will close to update, then opens with the new version automatically. Truly using the best experience that Silverlight has to offer.
Uninstalling the out of browser app is as simple as a right click in the app, and selecting from a dropdown “Remove this application”.
Kind of like a windows 8 experience with any pc.
Silverlight… ahhh what to say about Silverlight….. where to start.
1. We drank the Kool Aid. Microsoft told us how great Silverlight would be, how it would segregate the design team from the development team and deliver the benefits of keeping people within their specializations.
2. We spend years of time investing in Silverlight development. We get it, we can work with it and we can do amazing things with it. This and other cool projects including a MS Pivot interface to DotNetNuke and Microsoft CRM data.
MS Pivot and CRM – http://demo.interactivewebs.com.au/dnnpivot/dnnpivot_demo.htm
3. We kicked it’s butt. We were able to deliver anything we wanted using Silverlight and made it interface with a multitude of data sources at multiple times using XRM and other web services to pull data from both CRM and other data sources.
We get it, we can do it, we hate it and we regret the time we wasted after Microsoft mislead us into their Silverlight sphere.
Microsoft Silverlight Evangelist – We drank the Kool Aid
Silverlight never came close to delivering on any of the promises that Microsoft made about it.
It is tricky to develop in, it is poorly supported by even Microsoft, design tools are definitely lacking greatly, the development experience was a mine field of poorly documents bugs and broken features that required time and commitment to untangle the crap that Microsoft produced.
It was amazing to us how many things we were doing and solving that literally no one else was talking about. We felt like the first team walking on the Silverlight moon at every step of the way.
The end result is something that we are proud of. There are some cool features that we think make the project example above shine. But for all the time, and trouble invested to deliver it, it is just not worth it!
If looking at this and other similar projects again, we would use other technology to more quickly develop a very similar experience. There quite simply is nothing in Silverlight in interfacing with CRM that we can do easier other ways.
So there you have it. A good example of Silverlight with CRM, and the reason why we would suggest you use other technology yourself.
And check out that Silverlight Pivot link above. It is actually very cool too in what it does and how it does it. We have rigged this to work against any internet facing CRM environment including the Microsoft Hosted CRM.
We wrote this to help someone asking for a non commercial plug for a Silverlight in CRM example. We hope the above meets the requirement of that… but we are a development and CRM business, so we need to mention that if you need some cleaver interfacing with CRM. Then please contact us here http://www.interactivewebs.com/ContactUs.aspx.
We have other examples to show too.
Recently we launched a new website called Network You. The site can be found at networkyou.org.
Of particular interest on the site is a new module or ours soon to be released to the DotNetNuke Community called Mushroom Video Module.
The module will feed Youtube Play Lists from youtube.com directly into your site in an easy to manage and easy to use video feed.
The end result of the feeds looks like this:
http://www.networkyou.org/Network/GlobalVillage.aspx
With the video feeds being selected directly from a play list selector button that referenced a YouTube account name.
The module also uses the template system developed by InteractiveWebs for the display system that allows simple to load templates to be customized to the users requirements.
An example of the module with multiple feeds onto a single page is this one: http://www.networkyou.org/Network/Professionals/VideoTopics.aspx
We will be releasing the module to the public in the next few weeks. We would love to hear any comments!
Steps to add an Attachment Field to Feedback Designer Module for DotNetNuke.
The result is a form with file upload ability. The attachment is sent as an email attachment.
Please contact us for additional DotNetNuke Support requirements.
The Bulk Email module for DotNetNuke has a feature known as Bounce Email Monitoring, and it is probably a good idea to understand what it does and how it does it so we can explain how best to configure it.
When an email message is generated using the DotNetNuke Bulk Email Module, a list of all the email addresses that you have selected from multiple sources is generated into a database.
The lists that you select can include.
Once the list is complied, email addresses are removed.
Then the email messages are sent out and ticked off as being sent.
You can see that bounced email addresses will only be removed if they are on the bounced email list, and have bounced to a count matched the settings configured.
Periodically, the module will use the setting for the POP 3 account to look for email messages that it can add as a bounce. To do this, it will download all messages in the mailbox and look using some complex searching tools for email messages that appear to have bounced back from a failed send attempt.
Unfortunately email servers report bounce messages in different ways, so the code that reads the email messages and looks for bounce backs is long and complex. For this reason, the process of finding bounce messages should be kept to a minimum to reduce the load on the server.
The best way to reduce load is to minimise the number of mail messages that the process needs to check.
The best way to do this is three fold.
The process of downloading thousands of email messages, checking them all and processing them all can take hours. It will put a huge load on both the web server and your email server. It will increase your data transfer costs both on your web and email server.
So follow the suggestions and the result should be clean and fast.
Want to know more about email messaging in DotNetNuke.
Today we updated some code in our Contact Details module for DotNetNuke.
The module makes it easy to add your contact details to a page in DNN.
There is a map control function that uses Bing Maps that can be seen in the demo here: http://www.interactivewebs.com/contactdetails/Demo.aspx
We have updated the module today to support the use of SSL or https connections to the page that contains the module.
So here are the two ways to add the Bing Ajax control to your page in HTTP or HTTPS:
HTTP:
<script src=”http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.3” type="text/javascript"></script>
HTTPS:
<script src=”https://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.3&s=1” type="text/javascript"></script>
Now on the HTTPS version notice I changed the URL to start with HTTPS, this is what pulls from the secure site over at the good Bing folks. Also notice I added the “s” parameter and set it to 1, default is 0, this tells the Bing API to get the image tiles for the map from HTTPS.
Why? you ask.
Well it seems that the API determines what protocol to use for JavaScript and other parts from the document.location.protocol, however when it comes to the map tiles it looks to a global setting that is set based on the parameter being passed.
Today we have added support to the DotNetNuke Bulk Emailer module for WebFarms.
We have identified a feature of Bulk Emailer for DotNetNuke that has caused some issues with the running of the module on a WebFarm.
There is an automatic enable feature that checks when you start a bulk email message that the scheduler for the module in the Host / Scheduler is enabled. If it is not enabled, the module will enable it.
With WebFarms there are two processes that run at the same time.
This will cause duplication of sending email messages.
The solution is easy… just disable one of the schedule processes. However this will be automatically re-enabled by the module.
To solve this we have added an option to the Bulk Emailer Settings. This option enables you to tick that you are using a WebFarm, stopping the automatic enabling of iWebs BulkEmailer EmailSchedule process.
After you enable WebFarm mode, you will need to go into the Host Scheduler processes and disable all but one of the multiple processes for the iWebs BulkEmailer EmailSchedule.
The result will be that only one of the schedulers run and only one email message will be sent.
The steps in setting up the Outlook Social Connector for DotNetNuke on your local computer.
The steps assume that you have installed the DNN website module by InteractiveWebs called the Outlook Social Connector.
1. Close Outlook
2. Start the MSI installer “Setup_DNNSocialConnector”
3. Select Next
4. Use the default path, or select one, then select – Next
5. Select Next when ready to proceed
6. Wait a bit
7. Select Close
8. Open Outlook and in the Mail view, find an email message and expand the view for the Social Connector.
9. Select the + symbol under the contact image, and select “on another social network” from the available list.
10. Select “iWebs – DNN Social Connector” from the available social connector plugins.
11. Fill in the connection settings for your DotNetNuke Website that has the iWebs – DNN Social Connector module installed. And admin or host account is needed. Click Connect
When you browse an email message from a user who is registered on your website, you will see the activity that they have taken on your site. This includes activity on security roles, DNN Forums Module, and if you have updated to our modified Documents Module, activity on that module too.
Today we have added this feature to the DotNetNuke Advanced Login Module.
Normally DotNetNuke requires a user name to be entered at registration. The Advanced Login Module will automatically create a DNN user name at registration time, even if the token for User Name is not included in the registration form. This way you can allow users to register with an email address and no user name, while in the background the Advanced Login Module handles the user name for you.
If omitted from the registration form, the user name will be taken from the email address.
david@domain.com for example will generate a user name using all data from before the @ symbol.
david@domain.com = david as the user name.
If david is already taken as a user name, then david-01 or david-02 etc. will be used automatically.
This keeps the username familiar to users should it ever be provided to them, yet keeps the registration process as simple as possible.
The module is available as a Free DNN Module trial on our site.
