Create Instance menu option not displayed

I have quickly fallen in love with the Object Test Bench even though its really not much more than a souped-up, visual Immediate Window. However, in a project last night I was stumped to see that the “Create Instance“ menu option was not shown in the Class View as the Help file indicated it would be. I didn't think much of it and I just did my object creation from the Immediate Window which created the object in the OTB for me. However, this morning rational thought brought on by a decent nig

First real VS 2005 solution started

I bit the bullet today and started my first 2005 solution. I'm not talking about a “coding for fun” project. I'm talking about an enterprise solution. Specifically, to handle automated shipping and receiving for RFID...

Happy Thanksgiving

Happy Thanksgiving everyone! It's been a little while since I posted anything. I was onsite in Georgia refactoring some old code last week, and this week I've just been trying to get back on track with things. Next week an early distribution of the iMotion EdgeWare 5.1 platform is supposed to be shipped to me. Here is a summary of some of the changes and improvements...

Calculating a GTIN check digit

The EPCglobal tag data standards provides a calculation for the GTIN (global trade item number) check digit during SGTIN (serialized global trade item number) decoding. However, this algorithm although mathematically correct does not work computationally due to the way some computers handle modulus for negative numbers.

Addicting webpage

This site is oddly addicting. It is safe for work and anywhere for that matter, but you should turn off or down your volume unless you enjoy annoying music. Here's the link:

RFID in voting

I voted today for among others governor of Virginia. I was greeted by a demo of a new voting machine when I arrived at the polling place. Apparently, they're testing a completely computerized system. Right now they only have one machine and a whole bunch of ones with punch cards, but next year they're going to be all computerized.

Difference with Threading

I noticed a difference this weekend with how multi-threading works with the Thread class. Prior to CLR 2.0 you could perform cross-thread operations. Now, doing so generates an InvalidOperationException with the message “Cross-thread operation not valid: Control 'progressBar1' accessed from a thread other than the thread it was created on.”

Visual Studio 2005 First Impressions

I installed Visual Studio 2005 Professional yesterday and found a few hours to work with it. I've brushed on generics, anonymous methods, refactoring, and some of the other IDE goodies. So, far I'm very impressed and I wish I could transition over everything immediately from 2003...

Tip on binding to hierarchical data in UltraGrid

The Infragistics UltraGrid allows you to bind to hierarchical data. However, I didn't get the results I was expecting when I called SetBinding with a band collection that I created at design time. In my particular case the results of the child band included all of the columns from the child table...
