This topic will cover interop between VFP and .NET.

In this topic you will learn how to modify field attributes inherited from the PXStringList or PXIntList attributes. The demonstrated approach will make sure to not break functionality of the base Acumatica ERP product and require minimal maintenance, if any, while upgrading your customizations to a...

If you're using SAS to produce reporting of some sort, you're going to find yourself needing to copy a file at some point. I've mostly used this method for copying an excel template, and then dumping data via PROC EXPORT into the new file I've created. This is a great example I've found from Chris ...

Arduino's Liquid Crystal Library is a library for controlling LCD displays compatible the Hitachi HD44780 driver, characterised by their 16 pin interface. The 16 pins might be connected via an I2C interface. These displays contain a matrix of 5x7 pixel blocks used to display characters or small mono...

One of the challenges I faced when I first started using SAS was not only passing Macro Variable data into a PROC SQL pass-through, but having it resolve properly if it needed quotes around it. When passing a string like value or date/datetime into a PROC SQL pass-through, it most likely needs to ha...

Inserting an image in a word document using OpenXml require two actions: add the image inside the openxml and refer to the image in your Document if you only add the image to the openxml structure without refering it in the Word Document, the next time you "open / save" your document...

LINQ to Objects refers to the use of LINQ queries with any IEnumerable collection.

The intent of this topic to demonstrate some basic MIDI programs that show how to operate with the protocol and progressively add useful features that more complex applications require.

When laying out controls, it is easy to hard-code specific values in margins and paddings to make things fit the desired layout. However, by hard-coding these values, maintenance becomes much more expensive. If the layout changes, in what might be considered a trivial way, then a lot of work has to ...

MailboxProcessor maintains an internal message queue, where multiple producers can post messages using various Post method variants. These messages are then retrieved and processed by a single consumer (unless you implement it otherwise) using Retrieve and Scan variants. By default both producing...

The topic discusses how you can map one-to-many and many-to-many relationships using Entity Framework Code First.

Difference Lists in Prolog denotes the concept to know the structure of a list up to a point. The remaining of the list can be left unbound until the complete evaluation of a predicate. A list where its end is unknown is referred as an open list, ended by a hole. This technique is especially useful ...
