Code written in VBA is compiled [6] to Microsoft P-Code (pseudo-code), a proprietary intermediate language, which the host applications (Access, Excel, Word, Outlook, and PowerPoint) store as a separate stream in COM Structured Storage files (e.g., .doc or .xls) independent of the document streams.
In VBA, an assignment of variables of type Object is a shallow copy, an assignment for all other types (numeric types, String, user defined types, arrays) is a deep copy. So the keyword Set for an assignment signals a shallow copy and the (optional) keyword Let signals a deep copy. There is no built-in method for deep copies of Objects in VBA.
"Don't repeat yourself" (DRY), also known as "duplication is evil", is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place.
In computer programming, duplicate code is a sequence of source code that occurs more than once, either within a program or across different programs owned or maintained by the same entity. Duplicate code is generally considered undesirable for a number of reasons. [ 1 ]
VBA was restored in the next version, Mac Excel 2011, [21] although the build lacks support for ActiveX objects, impacting some high level developer tools. [22] A common and easy way to generate VBA code is by using the Macro Recorder. [23] The Macro Recorder records actions of the user and generates VBA code in the form of a macro.
Besides some static code analysis, it can be used to show violations of a configured coding standard. Duplicate code detection was removed [13] from Checkstyle. Eclipse: 2017-06-28 Yes; EPL: No Cross-platform IDE with own set of several hundred code inspections available for analyzing code on-the-fly in the editor and bulk analysis of the whole ...
October 2015) (Learn how and when to remove this message) In computer science , reference counting is a programming technique of storing the number of references , pointers , or handles to a resource, such as an object, a block of memory, disk space, and others.
The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.
