So easy, even a caveman can do it!

One of the things we most often develop for our customers are Content Management Consoles, so that they can manage the content on their website. Fairly standard, easy to implement, but most of the time, not very flexible.

Most of the time, our users are happy with what we provide them. But as the competition around us heats up, we find ourselves trying to build upon this, so that they can do more and more. But at the same time, keep the balance that it's easy for anybody to do. You see, Wyoming tends to be behind the technology curve in many areas, and many of our clients can barely use a computer, let alone write simple HTML. So we find, that if we provide tools, even as simple as the tools that are available on say, this blog site, they can become confused.

Onto another issue... In most cases, we can build a site for a customer that they can control in the same amount of time it takes one of our designers to have the page. So we leave it up to the customer. There is slightly more overhead, as it usually takes a bit of time to get a website setup for administration through CMS. But if we have to do anything in programming at all, it usually becomes a freebie to give them CMS for any given page on their website.

Since I've started this blog, I've gained a few ideas to allow customers to add more flexible content to their site. The question becomes really... is it worth us to add this ability for our customers?

Now that I've made the plunge to .NET 2.0 I think I'll start looking into adding these sort of components. All depends on a customer's site layout, but I think it can be a useful and very sellable tool to them. Right now seems to be a good opportunity for me, as I'm lacking projects to work on. (many things in the fire so to speak, but no hard signed contract with deposits in hand yet)

Until next time...

Blogging, Podcasting, and websites Ohh my!!

And maybe a bear or two since we live in Wyoming afterall.

Yesterday I went to Casper to speak on a panel about using the Internet to get across a message at the Wyoming Governor's Council Against Impaired Driving. Prior to this event, the largest crowd I spoke infront of was when I got married. It was a great event though, with people truly interested in how to get their message out more effectively across several media outlets. On the panel with me, were representatives from Radio, Print, TV, and the head of the Wyoming Public Radio Station. Certainly, it was interesting to have a peon like me on a panel of people that represent leaders of these other industries in our state.

Overall, since I enjoy social networking, I liked the opportunity to go and discuss this. Speaking to State Legislators, City Council members, leaders of organizations like MADD was certainly a new and enjoyable experience for me.

Afterwards, I met up with another client in Casper for a CRM application they would like to build. It was an interesting experience. At first their IT department was very stand offish against me, but their concerns were eased once I gave them a little background about myself. In the end, they want us to build something that works similar to M$ CRM that integrates into Outlook, but they don't want to pay the licensing fees to M$. *sigh* I'm more then happy to build them such an application, but I doubt I'll be able to bring it into a budget range that will satisfy them. Anyways, keep an eye out for this in my blog, because if we do move forward, I'm sure I'll be trying new things since this will be a Windows Application, not Web.

Implementing Google Maps

My project for Pinedale Properties implements Google Maps by showing property locations Below is the source code for how I implemented this solution. This code was done using ASP .NET 2.0.

First we have to insert the Script Source for the Google Map API... Don't forget to use your own key.

<script src="http://maps.google.com/maps?file=api&v=2&key=KEYHERE" type="text/javascript">script

Next up we need to modify the body tag to execute the script on load, and to call the GUnload() function on unload.

<body onload="Page_Load()" onunload="GUnload()">


On the control that displays the google map, I've added the following HTML Field...

<div id="map" style="WIDTH: 350px; HEIGHT: 600px">div>

Once all of that is finished, it's time to go play in the source code...

In the source, code, I first insert the Javascript code that is always present

'MAP HEADER CODE
sbGoogleCode.Append(""text/javascript" & Chr(34) & ">" & vbCrLf)
sbGoogleCode.Append("//
' place icon on map
sbGoogleCode.Append("var icon" & num & "= new GIcon();" & vbCrLf)
sbGoogleCode.Append("icon" & num & ".image = " & Chr(34) & "MapIcons/" & num & ".gif" & Chr(34) & ";" & vbCrLf)
sbGoogleCode.Append("icon" & num & ".shadow = " & Chr(34) & "images/shadow.gif" & Chr(34) & ";" & vbCrLf)
sbGoogleCode.Append("icon" & num & ".iconSize = new GSize(47, 53);" & vbCrLf)
sbGoogleCode.Append("icon" & num & ".shadowSize = new GSize(73, 53);" & vbCrLf)
sbGoogleCode.Append("icon" & num & ".iconAnchor = new GPoint(22, 53);" & vbCrLf)
sbGoogleCode.Append("icon" & num & ".infoWindowAnchor = new GPoint(4, 1);" & vbCrLf)
sbGoogleCode.Append("var point" & num & " = new GLatLng(" & lat & ", " & longitude & ");" & vbCrLf)
sbGoogleCode.Append("map.addOverlay(new GMarker(point" & num & ", icon" & num & "));" & vbCrLf)
End If
End Sub

This function takes in as parameters, the latitude, longitude, and a number. Latitude and longitude should be standard enough. The number tells the javascript which image to display on the map. (ie #1 for the first listing, #2 for the second, etc.)


Finally, after that code is generated, I add in the finishing touches to the Javascript.

sbGoogleCode.Append("}" & vbCrLf)
sbGoogleCode.Append("}" & vbCrLf)
sbGoogleCode.Append("//]]>" & vbCrLf)
sbGoogleCode.Append(")
sbGoogleCode.Append("script>")
Finally after that is completed, add the Javascript code to the page using the ClientScript.RegisterStartupScript function as shown here.

If (Not Page.ClientScript.IsStartupScriptRegistered("clientScript")) Then
Page.ClientScript.RegisterStartupScript(Me.GetType(), "clientScript", sbGoogleCode.ToString, False)
End If

As I move down the road, I see myself updating this feature with some additional features. Such as being able to click on a property in the list and having it highlight the map marker. Below is the finish product.



Fixing shortcomings in urlRewriter.net

One of my current projects, allows for the customer to create their own pages on the fly. As such, I needed to create a URL Rewriter so that they could create Search Engine friendly URLs. During my hunt I came across URL Rewriter .NET, an open source solution.

The initial problem that I ran into is, that it disables handling of the default page handlers. After following their suggestions and adding the following expression to handle default pages, I realized it didn't handle subdirectories very smoothly.

<rewrite url="^(.*)/(\?.+)?$" to="$1/default.aspx$2" processing="stop">

Basically, http://www.paulnkaty.com/test/ would resolve fine. http://www.paulnkaty.com/test would return a 404 not found error. For now, until I get a chance to look through the source code and find the cause of the problem, I thought I would give you a work around.

<redirect url="(.*)/test$" to="$1/test/" processing="stop">

For this, it looks for the URL to end in the directory name, without a trailing slash. If it matches this case, it redirects the URL to the same location with a trailing slash. Luckily the application uses Regular Expression (RegEx) to parse the URL. Admittedly, this is a weak point for me, so it'll take some time before I can really find a nice solution for this project.

Overall, it's not a terrible solution, but I will probably look down the road at some better ideas. One limitation I do have, is that our primary web server is still on IIS 5.

URLRewriting in the land of Global.asax

Earlier I wrote about using URLRewriter.net. It's a decent piece of software, but has some serious drawbacks, especially since it forces you to modify the IIS configuration for a specific website. As a webmaster, trying to keep that straight on 1500+ websites isn't exactly an ideal solution. So today, I'm going to present you with a fairly basic method in this case of handling it in the global.asax file. This method is handled inside the Application_BeginRequest Subroutine.


Dim incoming As HttpContext = HttpContext.Current
Dim oldpath As String = incoming.Request.Path.ToLower()
Dim pageid As String
Dim DynamicPageName As String
Dim BareName As String
Dim regex As System.Text.RegularExpressions.Regex
Dim matches As MatchCollection
'------------------------------------------------
' URL rewriter for WebPage.aspx?pageid=xxx
'------------------------------------------------
' set unique page name for dynamic pages in web.config
DynamicPageName = ConfigurationManager.AppSettings("cfgWebPageName")
' get the bare name for moving pageid in the string
BareName = RemoveFileExtension(DynamicPageName)


Here is the RemoveFileExtension function. We can't use the Path.GetFilenamewithoutExtension function because of the potential case for a QueryString at the end of a dynamic page:


Function RemoveFileExtension(ByVal parmFileName as String) as String
   Dim FullLength as Integer = parmFileName.Length
   Dim RightStringToCut as String = parmFileName.Substring(parmFileName.LastIndexOf("."))
   Dim RightLength as Integer = RightStringToCut.Length
   Dim NewStringLength as Integer = FullLength - RightLength
   Dim NewWebPageName as String = parmFileName.Substring(0, NewStringLength)
   Return NewWebPageName
End Function


Now onto the rest of our application...


regex = new System.Text.RegularExpressions.Regex(BareName & "(\d+).aspx", RegexOptions.IgnoreCase Or RegexOptions.IgnorePatternWhitespace)
matches = regex.Matches(oldpath)
If matches.Count > 0 Then
   pageid = matches(0).Groups(1).ToString()
   incoming.RewritePath(DynamicPageName & "?pageid=" + pageid)
Else
   incoming.RewritePath(oldpath)
End If


In the above code, it is specifically looking for a page named "webpageNN.aspx" where NN is equal to the page ID. So the page would be labeled as webpage18.aspx. It then rewrites the URL to webpage.aspx?pageid=18. The user, searchengines, etc. still see webpage18.aspx though. Easily enough, this could be expanded to be used with more friendly URLs, such as mywedding.aspx which would rewrite to webpage.aspx?pageid=18 via the addition of database information.

Adding a 3rd party form in Active Admissions

Recently, I was asked by another college how we successfully implemented forms that we want to submit to third parties, such as our Library system's search network, our Google search, etc. So today, I'm going to cover how that is done. This trick is fairly simple, and best implemented within XSLT.

First you'll create your XSLT document with the following shell...

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ACControl="urn:This:Control" xmlns:ACXslt="urn:ActiveCampus:XSLTLibrary" exclude-result-prefixes="ACControl ACXslt">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="/">
<!--- Put your Form Here -->
</xsl:template>
</xsl:stylesheet>

As you can see in the middle, I've highlighted where your form code will eventually go.

Now we'll start creating your form. In this example case, we are going to use a simple Google Search. Below is the Textbox for the search.

<input type="text" name="q" />

This is fairly straight forward... now comes the real fun, the Submit Button.

<input type="submit" name="b1" value="Go" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;b1&quot;, &quot;&quot;, false, &quot;&quot;, &quot;http://www.google.com/search&quot;, false, false))" id="b1" />


Hopefully while looking at this you'll notice that instead of actually putting up a quote, in the XSLT, I am actually putting in encoded quotes. This is very important otherwise it won't work.

While I'm on the subject... this would be much more straight forward if Datatel enabled the ability to insert Javascript directly into their Rich Text Editor. Unfortunately they turn that capability off, and the only way to get it switched is via a programmer switch. So I encourage all Active Admissions users to contact Datatel and submit a request to get it turned on. Part of the reason for this is, that I believe schools should have the capability to use all technology, and not be limited. Give us the freedom to create!

Feel free to post, or contact me if you have any questions on this process.

Cya,
Paul

Install notes for installing ActiveCampus CMS/ActiveAdmissions

Well I got a new toy a couple of weeks ago. My very own development server for making changes to ActiveCampus/ActiveAdmissions without the fear of blowing up our live website. Below are some key notes that will probably help you on your way to installing this software. If you're like us, Datatel came in and did the initial installation. So I never had any experience doing it myself. Kinda scary if we ever had a blow up that required a new installation... So below are some notes that I made.

1. Create the Database and user ahead of time. Initially give the new user global powers, and after you are finished installing, backdown the permissions to the appropriate level.

2. Most importantly. Nowhere in their requirements or documentation does it talk about this... but if you don't install it, the software will never work. You must download and install Microsoft's Web Services Enhancements (WSE) 2.0 AND 3.0 for Microsoft .NET. It took me a good 2 or 3 hours to track down the solution. So hopefully this saves somebody that amount of time.

Outside of that the install went fairly smoothly. It requires quite a bit of hands on work, because their installer is not setup to configure the log directories or modify folder permissions. But after you that up and running, things should smooth out for you.

So now that I have my test install up and running... hopefully I'll be posting more tricks and tips from working on my development environment.

For those keeping track at home.. my test server is a Dell Poweredge with Dual Quad-Core processors, 12GB of memory, and 2 Raid-1 Drives. Way overkill for a dev server, but I'm happy. :)
