This post is one of the more esoteric ones where I delve into the geeky details of some of my programming work. I know – it’s really sexy, isn’t it?

I have mentioned the bridge application I developed that helps make payrolls run faster, helping client employees get paid faster, and so forth, using Microsoft Access 2003 with VBA, ADO, Excel, Office, etc.

Some members of the company are starting to migrate to Office 2007, and we can see the entire organization moving there soon. A few weeks ago, I tried opening and running one of the bridge applications in Access 2007, and it bombed horribly, specifically in how I’ve written it to use the Office 11 FileSearch object.

I just found a couple of few documents on MSDN and TechNet that I hope will help understand what is involved in the migration:

• Transitioning Your Existing Access Applications to Access 2007
• Migration Considerations for Access 2007
• Changes in Access 2007
• Office 2007 Object Model Reference
• Migrating a VBA Solution to a Visual Studio Tools for Office Add-In

Okay, to be honest, I picked that last item because it sounds interesting.

Part of what I do in my current work is produce ad hoc reports. I often am asked about the information in them because it doesn’t appear to match what decision makers had assumed.

The information on the reports is only as good as the raw data that exists in the system, I tell them. If the company no longer do business with a client, for example, and yet the client is still marked active in the system, then the client still gets counted as an active client. The same goes for employees. Active employee count may appear high, but when it comes down to the actual numbers of employees getting paid, the number is much smaller in some cases.

Helping managers and other decision makers understand these truths is one thing that I appreciate doing in my work.

Clients email the company their payroll files, and the columns on the payroll indicate Regular Hours, Overtime, Vacation, and so forth. To make the bridge application work, I and the other developer map the program that assigns payroll items based on this layout. It only works, however, when the layout is consistent. Whenever a client changes it by adding or deleting a column, the program generates an error.

One thing I have found so helpful in resolving errors is the Error Handler function. I use the Err object in Visual Basic, but I also add additional information such as the module name and procedure name where the error occurred. The user gets a message box, which is helpful for them, but I also wrote the program to create a log file with the same information so that I can go back and see errors that have occurred.

One hour ago I got an e-mail from a payroll specialist, telling me that a client with 107 active employees had added a column to their payroll file and asking if I could fix their bridge application to allow for the new payroll item.

I opened the code, and after I made the changes needed in a few class modules, we were good to go. I tested it out on my machine and then put it out on the network for the payroll specialist to use.

I was able to get this done so quickly because there were only a few places to add some more code. Having the system set up like this was very efficient.

The company didn’t have a process in place to make sure that this one client receives their 401(k) information on a regular basis. I had developed an application last fall for this specific client to produce the information, but there was no one set up specifically to run the application on a regular basis.

I was contacted earlier today to set up this application on several people’s computers. Interestingly enough, everyone could get to the application, since it exists on a networked drive, but, to make things as easily accessible as possible, I prefer to put a shortcut to the application on users’ desktops.

After I finished that, I sent an email to everyone affected, letting them know about the application, and letting them know how to get the report.

About 15 minutes later, I was summoned to a user’s computer because there was a problem with the report details. She was running the report for last week, but the Last Pay Date for several employees was for this week.

As I looked into the program, I realized that all the other details were correct except for this Last Pay Date, which gets updated whenever a payroll is run. I began brainstorming other ways to get the correct date.

One option was to look at the last pay check date for the date range specified, which is from the first of the month to the date the user selects on a form. That would make sure that date for employees who are getting paid this week is the date the user selected.

As I thought about that, I realized I was not finished. What if we run this report a month from now, and an employee had been terminated this month? The client would still want that employee to show up on the list.

I continued brainstorming, and wrote some mock VBA code on my marker board. Satisfied with that, I created a function, tested it out with various scenarios, and eventually came to a solution that will either use the last pay date for the reporting range OR the Last Pay Date field from the other data table.

I generated the report and sent it off to the client service representative, who will then forward it on to the client.
