VisendoSMTPExtender Management Web Service

Published by under .NET,Programming,Software

Background:

For work, I’m using a Windows 2008 Server virtual machine for doing all my SharePoint and .Net development on.  As it has got all of the cool stuff I’m working on, it is also the machine that I use to demo what I can do to clients.  Recently I’ve had a bit of a serge in the number of clients wanting to see Nintex Workflow 2007 (NFW2007) for SharePoint.

One of the cool features of NWF2007 is the whole Lazy Approval system, whereby users don’t have to go into SharePoint to approve to decline requests, they can just reply to the notification email with “approved”, “declined”, “ok”, “yes”, “no” or any other recognised word as the first line of the email.  In or to demonstrate this I need to setup and email system on my local machine.  The SMTP (sending) side of things is easy as it is built in to Windows 2008.  However, POP3 is a bit of a problem.  Previous version of IIS had a simple POP3 service but that has been dropped in IIS7.  The Microsoft way would be to install Exchange Server but that is a little too heavyweight for what I am trying to acheive.  Luckily a company called Visendo provides a free solution to plug the gap.  So now I can demo Nintex notification features.

Another feature I also wanted to demonstrate was setting up Active Directory accounts and then using those new accounts.  Nintex has got actions that allow you to interact with Active Directory but to then do anything usefull with the account required modifying xml config files and restarting the Visendo service.  But Nintex can call web services, so I’ve created a web service that has an AddAccount and DeleteAccount methods to update the Visendo configuration and restart the service.

I’ve made the source code for this web service freely available should anyone else want to have this sort of functionality: VisendoSMTPService.  The code is written against .Net 3.5 and is provided “as is” with no sort of warranty and is most definitely NOT recommended for live systems.  The code is released under a BSD License.

ScriptManager vs ClientScript

Published by under .NET,General,Programming

As part of a Microsoft Dynamics CRM customisation project, I was recently tasked with modifying an ISV add-in page so that individual sections of the page could be refreshed without having to refresh the entire page.

That in itself was nice and easy, it just required the use of a couple of UpdatePanel and UpdateProgress controls to be dropped on the page along with a ScriptManager control to handle the partial postback requests.

However, there were a couple of gotchas that I didn’t foresee.  Along with the partial updates, the client wanted the parts of the page to load the first time after the page had first loaded in the following order:

  1. Load base page.
  2. Start load of Application Status section.
  3. Start load of Risk section.
  4. Start load of Alerts section.

Unfortunately, the ScriptManager that comes with ASP.Net AJAX only handles one postback at a time.  Any subsequent postbacks take precedence over earlier request, which is fine if you only have one update panel on a page but this initially resulted in only the Alerts section being loaded – the other postbacks being canceled.

Luckily I found a very useful post on Amit’s Blog: Asp.Net Ajax UpdatePanel Simultaneous Update.  This post provides code that queues postback requests.  Ideally I would have liked to have the requests happening at the same time, but this is the next best thing.

The other problem that I found was that one of the sections on the page had previously been dynamically creating and reqistering script that got loaded and executed when the page loaded using:

Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
    "ShowNavBarItem", script.ToString());

Unfortunately that doesn’t work with the AJAX ScriptManager.  Instead I had to change the code to use the ScriptManager to load and execute the code using the following:

ScriptManager.RegisterClientScriptBlock(updatePanelApplications,
    typeof(UpdatePanel), "showNavBarItems", script.ToString(), true);

This means that each time the section is updated I can re-generate the script and it will be executed again.

With this AJAX loading and some enhancements to the SQL code, users now get a much fasted load and response time for the page as the no longer have to wait for the whole page to be rendered before seeing information appearing on the page.

Character Counter

Published by under .NET,Software

Whilst reading an article I was curious about the number of commas and full-stops that the author used – when you become an editor of a newsletter you start to think about things like this.  After hunting around the various utilities on my system I discovered that I didn’t have anything that could easily do this.  So, I did what any self-respecting programmer would do and threw together a quick app to do it for me.

I have made both the source code and pre-compiled binary available for download under a BSD license (share, remix, no endorsement).  It is written in C# and requires the .Net 2.0 framework, if you want to compile the source you will probably require MS Visual Studio (Express should be ok), although it may work with SharpDevelop or Mono.

It is a console application (sorry, no pretty GUI this time) that reads the contents of input.txt (in the same directory as the app), it then counts the occurrences of each character and outputs the results to the console. Simple!

If you make any improvements to the code please leave a comment and/or email the changes to me: gringod [at] gmail [dot] com.
