I ran in to this weird error last night when trying to send a DataTable as a parameter to a webservice.  It took me a minute, but finally the underlying exception showed the issue.  I had created the DataTable myself as a method for transporting multiple parameters, and had not given the newly defined/created DataTable a TableName.  So I set the TableName property on the DataTable, and viola! Everything worked as exepected.

One of the many things I have been working on lately, is actually helping another microISV with a project of theirs.  Snowmint Creative Solutions consists of 3 people who are primarly Mac developers.  We made contact earlier this year, and I have been involved in helping them port one of their products over to the Windows platform using VB.NET and .NET framework v2.0.  The project took quite a bit longer than we all had hoped it would, but my other projects workload as well as my learning curve of understanding how the Mac version operated delayed things.  But, it's out now, and we are already working on the next version.

 



You can check out the home page for the product here.

It has been a great pleasure to work with Snowmint, as they are...

So I've been doing some project work for different companies around Memphis, and have been working a lot with ASP.NET lately.  I'm in the process of creating a simple call tracking system for a customer, and I'm using a GridView on one of the pages.

I setup the GridView, created the DataSource, pointed it at a Business Object that I had created, but everytime I got to the page I would get the following error/exception:

-------------------------------------------------------------------------------------------------------

No parameterless constructor defined for this object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.-------------------------------------------------------------------------------------------------------

I guess this...

For those of you who are C# programmers and a little miffed about the new “My” namespace that's coming out for VB.NET 2005 developers, there's hope.  C#.Net 2005 is going to be released with a “that” namespace that will closely mimic the “My” namespace that's been discussed by so many...

via IDesign site:

“The My class in VB often simplifies and streamlines many operations, from Network programming to clipboard, to audio access, and so on. What takes sometimes a programming fit in C# can be done in one line using the My class in VB. If VB has Me and My, then C# should have this and That. The That class is the C# equivalent of the VB My class. It is a static class that uses the VB implementation as much as possible, and it requires adding a referencing to Microsoft.VisualBasic. The That...

Do you know how computer thinks? Play chess with a computer and see "inside PC's brain".

This is a VERY cool site.  It's a java chess game, and after you make your move you will see the computer decide which move it should make based on what it thinks you will do...VERY COOL STUFF!

I was at my wife's office for lunch today and saw the latest edition of Fortune Small Business, which the cover article spoke of Microsoft using Anthropolgists to study small businesses.  Of course Scoble beat me to blogging about it...

Using Anthropology is something new in the industry that hasn't quite made it to the mainstream. The article discusses Microsoft's efforts to better understand their small business customers and what their “friction” points are in their day-to-day operations.  I thought it was funny after reading the article that Fortune didn't do a good job (in my opinion) of helping people understand why Anthropologists are perfect for this type of work.

So here's my attempt:

First let's define Anthroplogy: The scientific study...

“...the 8.0 VB language specification posted up for downloading. It covers all the new language features in VB 2005 and should be completely current with Beta2.”

This is a interesting document as it describes all the ins and outs of the Visual Basic language and changes that are coming with the next release of Visual Studio.

It's hard to believe it's been almost 2 years since the last Professional Developers Conference (PDC) in Los Angeles, but I was there.  I saw what is now finally beginning to come out.  Avalon, Indigo, Whidbey, Yukon...

Registration for the next PDC opened today.  You can get more details here.

I'm planning to go along with a few of my developer friends.  I don't think my company will pay for it though, so I need to raise the money myself....I figure it'll cost me about $3,000 after everything is said and done (Conference Registration, Flight, Hotel, Rental Car, Food not supplied by MS, etc...)

I need to figure out how to add one of those donation buttons to my blog here, so people can help send me to PDC! 

I'll be kicking my after-hours/weekend consulting into overdrive to raise the extra money I need to go to this conference. 

It's worth every penny, especially if you are working on any projects that are in the early stages. ...

I’ve been downloading a LOT of sample, example, and open-source code lately. I’ve got this idea, and I’m doing research on it. For the first time ever, I’m actually trying to design the idea before I start writing code. Novel concept isn’t it? One of the more interesting articles I’ve read lately while doing some research for my project was on MSDN. In an article titled "Plug-Ins: Let users add functionality to your .NET Applications with Macros and Plug-Ins", Jason Clark does an excellent job first explaining why making an application extensible is so important, and then moves into describing the functionality in the .NET framework that allows for making extensible applications. He covers all aspects of extensible applications, from FINDING assemblies that could be loaded as plug-ins for your application, actually loading them at run-time, how to implement secured and unsecured plug-ins. It’s a full-featured article that is a must read for anyone who’s working on an application that will have any extensibility functionality in it. For me the only downfall of the article was that all the code samples were in C#. I consider myself a fairly competent programmer, and can read C# quite fluently. But, I’ve never taken the leap to actually become C# programmer in full force. So, to make things easier for myself, I converted all of the code samples provided by Jason to VB.NET....

So much going on, so much to talk about and still I say nothing…

 

I’ve been working fairly hard lately, and have been working on my own projects at night even harder so my blog has suffered.

 

Enough excuses, enough whining, on to some real content…

 

For those of you who don’t know I work for a publicly traded company where I’m a VB.NET programmer (hold the jokes, hold the rotten tomatoes).  I work on anything from simple ASP.NET reports to a complex WinForms application for allowing our customers to run their entire businesses.

 

First my history with programming…

 

I started out in “programming” writing in ROM-BASIC for an Atari 800 that somehow my oldest brother convinced my parents to buy us.  Man we were cool, we’d spend an entire day typing in some program (usually a game) from the latest magazine, then we’d spend most of the night debugging it to find which line we’d mistyped and finally we were ready to play it for about 15 minutes...
