I'm such an old fuddy duddy... that I'd never really tried COM wrapping on C# objects.
But today all that changed...
This blog post helped lots:

I'll try to actually post the code on this later... it's a nice way of extending a web app in an Intranet environment (it's not for Internet...)

An excellent explanation of the confusion that reigns between ASP.Net 2.0 and 3.x
This is something I've come across more than once now - people complaining their ASP.Net 3.5 applications are running as 2.0 and not being able to set them in IIS...
Here's a superb explanation of what 3.0 and 3.5 added to 2.0 - and how they did it without changing the core runtime

Adding direct SQL editing/browsing access to any website...
I was editing a nopcommerce website that I only had http and ftp access to - no sql access.
So I needed a way to execute some SQL scripts.
To do this I added (to the administration pages) the following
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SQLRunner.aspx.cs" MasterPageFile="~/Administration/main.master" Inherits="NopSolutions.NopCommerce.Web.Administration.SQLRunner" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cph1" runat="server">
SQL:
<br />
<asp:TextBox ID="tbSQL" runat="server" Columns="80" Rows="10" TextMode="MultiLine">
</asp:TextBox>
<br />
<asp:CheckBox ID="cbScript" runat="server" Text="Run as script" />
<asp:Button ID="btnGo" runat="server" Text="Go" OnClick="btnGo_OnClick" />
<br />
<asp:Panel ID="pnlOutput" runat="server" Visible="false">
<asp:GridView ID="grdResults" runat="server"></asp:GridView>
</asp:Panel>
<asp:Label ID="lblResult" runat="server" >
</asp:Label>
</asp:Content>

}
catch (Exception exc)
{
lblResult.Text = string.Format("Exception seen - {0} - {1}", exc.GetType().Name, exc.Message);

ASP.Net AJAX problems - Gray Google Maps
While adding some google map functionality to a custom nopcommerce build I came across some "gray map of death" problems with the gmaps. Basically the maps seemed to be offline - they didn't draw properly and they didn't respond correctly to mouse events (double click or drag).
Searching, I found a few references to these sorts of problems - most of which seemed to be caused by css issues (float:left seemed to be a common cause).
However, eventually this thread showed me the way forwards - http://www.reimers.dk/forums/thread/1251.aspx.
Basically, the initialisation of my AJAX tabs was causing the google map to lose its positional information - so to reset it I needed to call map.checkResize() - which seemed to cure the problem :)

Creating indicies on views
Because runsaturday maintains two user databases - one for yaf and one for dnn - I wanted to create a lookup table from one set of userids to the other.
And the easiest way of doing this automatically was a view with an index.
But to create the index on the view - I had to remember the SchemaBinding trick - see http://www.mssqltips.com/tip.asp?tip=1610 for more information about schema bound views.

The Joel Test
I've not really seen this before - but just been sent it within the UK MSDN Flash today - http://geekswithblogs.net/iupdateable/archive/2009/08/05/uk-msdn-flash-poll-how-did-your-software-team-score.aspx - interesting stuff:
The Joel Test
- Do you use source control?
- Can you make a build in one step?
- Do you make daily builds?
- Do you have a bug database?
- Do you fix bugs before writing new code?
- Do you have an up-to-date schedule?
- Do you have a spec?
- Do programmers have quiet working conditions?
- Do you use the best tools money can buy?
- Do you have testers?
- Do new candidates write code during their interview?
- Do you do hallway usability testing?
And once you have answered those questions, share with the rest of us how you scored.
I think I score a 8 or 9... I'll let you guess which ones I don't do... and which one I half kind of do.

ModuleLoadException - RSS/News with DNN5
Saw this problem with the RSS/News feed module under DNN5 - using ASP.Net 3.5 SP1.
Eventuallly... after several hours... tracked it down to the file RssModule.ascx which hard codes the System.Web.Extensions version number:
<%@ Register assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" namespace="System.Web.UI" tagprefix="asp" %>
Replaced this with

And life was OK again (phew!)

Problems precompiling site - BC30560: 'ScriptServiceAttribute' is ambiguous
Installed a brand new DNN 5.0.1 installation.
Upgraded web.config to 3.5 Framework version.
Added my own modules.
Tried to precompilte....
But sadly things went wrong... 'ScriptServiceAttribute' is ambiguous
Spent a long time looking inside web.config for the problem.... couldn't see it.
Eventually discovered that something (not sure what - was it in DNN?) had installed an old version of system.web.extensions.dll into my bin directory....
Grrrrrrrrrrrr
(at least next time I'll check there first)

Got the plugin working on Firefox... now Chrome
The plugin worked on Firefox!
But under Chrome it kept crashing....
The problems seem to be down to:
1. A whole load of test and demo code in CPlugin::CPlugin - in plugin.cpp - couldn't be bothered to find out which bit of it caused the crash - it was all just demo code from the sample - so I cut it all out!
2. Problems with the way the sample code used malloc and strdup to allocate memory... these need to be replaced with NPN_MemAlloc for Chrome (and really for Firefox too!)
This page seems to help a bit...
http://code.google.com/p/vacuproj/wiki/SciMozNotes
But really it is hard work to debug!

Starting out on Firefox plugins
I've been working on a new Firefox plugin.
stage one... was to get the code I wanted to working as an ActiveX control inside Internet Explorer.
stage two... was to then start on getting the mozilla code working - this guide for Visual Studio building is a little out of date - but still seemed to basically work:
https://developer.mozilla.org/en/Compiling_The_npruntime_Sample_Plugin_in_Visual_Studio
The main things that didn't work were:
- problems with changes in function names
- problems with int32_t types which seem to have been removed!

Eeeeek - back in C++ land
Spent a long time today trying to get a project to link :)
Eventually worked it out - but it took some decoding of name mangling - http://www.kegel.com/mangle.html - it eventually became "obvious" that the library I was linking against was built using VC++ 6.0 - before w_char as a type was introduced - so one of my names didn't match one of the mangled names...
I'm really finding it hard to work in C++ after 3 years of mostly C# though!

Making an AJAX TabPanel really invisible
If you want to make a TabPanel invisible using the ASP.NET AJAX
TOOLKIT then it seems you have to make the header text invisible too.
I did this using:

ASP.NET textbox multiline maxlength
Very useful and simple javascript if you want to protect a multiline text box from enterting too many characters!
http://geekswithblogs.net/mahesh/archive/2007/12/27/asp.net-textbox.multiline-maxlength.aspx
Or something like that...
http://geekswithblogs.net/mahesh/archive/2007/12/27/asp.net-textbox.multiline-maxlength.aspx
function CheckCount(text,length)
{
var maxlength = new Number(length); // Change number to your max length.
if(text.value.length > maxlength){
text.value = text.value.substring(0,maxlength);
alert(" Only " + maxlength + " characters allowed");
}
}<asp:TextBox ID="textBox" onKeyUp="javascript:Count(this,100);" onChange="javascript:Count(this,100);" TextMode=MultiLine Columns="5" Rows="5" runat=server>
</asp:TextBox>Or something like that...
Some useful pages for OpenSocial
Just starting to look at this now...
Here's some useful OpenSocial pages I've found:
This reply is very useful with links and ideas: http://www.mail-archive.com/opensocial-api@googlegroups.com/msg04079.html
Here's the Ning hello world application: http://developer.ning.com/forum/topic/show?id=1185512:Topic:4655&page=3&commentId=1185512:Comment:87952&x=1#1185512Comment87952
The iGoogle page is very good - and I use their sandbox quite a lot! - http://code.google.com/apis/igoogle/docs/igoogledevguide.html - sandbox at http://www.google.co.uk/ig?refresh=1
(I also find it quite funny that Google has a "legacy" gadget section already! http://code.google.com/apis/gadgets/docs/legacy/gs.html#Scratchpad
Here's the developer's guide http://code.google.com/apis/opensocial/docs/0.8/devguide.html
An example gadget (not quite opensocial) on CodeProject - http://www.codeproject.com/KB/ajax/igoogle_gadget.aspx
MySpace also has opensocial capabilities - http://developer.myspace.com/community/opensocial/helloworld.aspx (I never use MySpace - but maybe I should take a look one day)
The www.opensocial.org site is very useful - e.g. here's a tutorial - http://wiki.opensocial.org/index.php?title=OpenSocial_Tutorial and here's a list of containers - http://wiki.opensocial.org/index.php?title=Containers
Another interesting tutorial - http://www.devx.com/webdev/Article/37952/0/page/3 (plus also see their Gadget tutorial - http://www.devx.com/webdev/Article/35007/0/page/4)
Not sure about this link - it's about xml2json - but I think there may be better ways available now - http://www.phdcc.com/xml2json.htm

Changing YetAnotherForum to display time as "x minutes ago"
This really demonstrates the beauty of open source!
I've got a lot of international visitors to www.runsaturday.com - so I wanted to avoid time zone specific times (yes - I know YAF does let each user customise the time zone, but that doesn't really help when I get so many guests through)
So ... I decided to adopt the facebook/twitter approach - to listing times like "23 seconds ago" and "in the last week".
It was remarkable easy to change. Here's the main new code:

So ... I decided to adopt the facebook/twitter approach - to listing times like "23 seconds ago" and "in the last week".
It was remarkable easy to change. Here's the main new code:
/// <summary>
/// Formats a datetime value into "friendly terms" - let's hope this works!
/// the date is yesterday or today -- in which case it says that.
/// </summary>
/// <param name="o">The datetime to be formatted</param>
/// <returns>Formatted string of DateTime object</returns>
public string FormatDateTimeTopic(object o)
{
//string strDateFormat;
DateTime dt = Convert.ToDateTime(o) +TimeOffset;
DateTime nt = DateTime.Now+TimeOffset;
TimeSpan diff = nt - dt;
double totalSeconds = diff.TotalSeconds;
double totalMinutes = diff.TotalMinutes;
double totalHours = diff.TotalHours;
double totalDays = diff.TotalDays;
try
{
if (totalSeconds < 15.0)
{
return GetText("MomentsAgo");
}
if (totalSeconds < 100.0)
{
return string.Format(GetText("SecondsAgo"), totalSeconds);
}
if (totalMinutes < 100.0)
{
return string.Format(GetText("MinutesAgo"), totalMinutes);
}
else if (totalHours < 10.0)
{
return string.Format(GetText("HoursAgo"), totalHours);
}
else if (totalDays < 1.0)
{
return GetText("InTheLastDay");
}
else if (totalDays < 2.0)
{
return string.Format(GetText("ADayAgo"), totalDays);
}
else if (totalDays < 30.0)

return string.Format(GetText("DaysAgo"), totalDays);
}
else
{
return dt.Date.ToString("dd MMM yy");
}
}
catch (Exception)
{
return dt.ToString("f");
}
}
Old code was:
/// <summary>
/// Formats a datatime value into 07.03.2003 00:00:00 except if
/// the date is yesterday or today -- in which case it says that.
/// </summary>

public string FormatDateTimeTopicOld( object o )
{
string strDateFormat;
DateTime dt = Convert.ToDateTime( o ) + TimeOffset;
DateTime nt = DateTime.Now + TimeOffset;
try
{
if ( dt.Date == nt.Date )
{
// today
strDateFormat = String.Format( GetText( "TodayAt" ), dt );
}
else if ( dt.Date == nt.AddDays( -1 ).Date )
{
// yesterday
strDateFormat = String.Format( GetText( "YesterdayAt" ), dt );
}
else if ( BoardSettings.DateFormatFromLanguage )
{
strDateFormat = dt.ToString( GetText( "FORMAT_DATE_TIME_SHORT" ) );
}
else
{
strDateFormat = String.Format( "{0:f}", dt );
}
return strDateFormat;
}
catch ( Exception )
{
return dt.ToString( "f" );
