How to calculate date/time differences in Visual RPG for .NET
Back in the halcyon days of RPG II/III, calculating differences between two dates or times was enormously complex and took tons of code (does anyone else remember Paul Conte’s multi-part "Ultimate Date Routines" series in NEWS/400 magazine?). Well, that was then and this is now. .NET offers superb date calculation capabilities. Let’s take a brief […]
Working with the ASP.NET ListView and row and column clicks
See code on GitHub The ListView is a worthy alternative to the GridView control. With the ListView control, you are 100% in charge of the markup produced. This makes the ListView much better suited to pages where you need complete control over the markup, such as when you’re using a CSS framwork like BootStrap. However, […]
Using FTP to send and receive IBM i source members
Occasionally you might need to send or receive a source member from/to your Windows PC and the IBM i. Assuming your IBM i has FTP enabled, it’s a snap to perform this task with Windows’ built-in FTP client. To further explore FTP on Windows, see the list of Windows FTP commands .

Printing to PDF with ASNA Visual RPG for .NET
Distributing reports as PDF files is a very common practice in the enterprise. ASNA’s DataGate print files are designed to print to one of your installed Windows printers. Printing to PDF with AVR is therefore a pretty simple task of using a PDF print driver and then printing to that virtual printer. These drivers redirect […]
The .NET Saga: From .NET Framework to .NET
In early 2002, Microsoft officially released .NET Framework 1.0 to the world. This was a big bet from Microsoft that aimed to replace the aging and ailing COM development model. .NET Framework was part: a competitive response to Java an amalgam of various languages and integrated developer tools an attempt to make it much easier […]
How to stretch ASP.NET session timeout
Most AVR-driven ASP.NET Websites use the Session object to save the state of some variables. For example, a customer number may be stashed in a Session variable like this:
|
1 |
Session['custom-number'] = 673 |
when the user requests a page (the same page or another page), that value is available for your logic to fetch and do something with. For […]

How to upgrade ASNA DataGate WebPak
The ASNA WebPak is the DataGate client for Windows Servers. It is to Windows servers what the Client Deployment binary is to Windows clients. The WebPak should be installed on any Web server on which you’ve deployed an AVR ASP.NET Website/Web services or Monarch migrations. Installing WebPak is very simple; you just run the WebPak’s […]
Working with numeric dates in AVR for .NET
Working with dates is something many RPG programs do extensively. In the old days of AVR Classic, we used to have to use lots of data structures and other special-case code to format dates, convert dates. It was also quite challenging to do date arithmetic and perform other sophisticated date manipulations. AVR for .NET’s Date, Time, and *TimeStamp help resolve all of these issues. However, many shops still store dates (and times) as numeric values in their database. This seems to preclude using some of .NET’s really great date handling and manipulation. This article changes that and shows how to integrate your numeric date and time values with .NET’s great date and time handling.
How to easily take an ASP.NET site offline
