New demo code for articles #9 & #27

I've just added demo code to my delphidabbler/article-demos repo for these two articles:

  1. How to programatically detect installed versions of Delphi
  2. How to get notified when the content of the clipboard changes

The first one is new and provides code that does just what the title says.


The second one has been dragged out of a old Assembla SVN repo and converted to Git. It provides a simple editor where text can be cut, copied and pasted. The clipboard change notifications are used to update the state of the Paste button depending on whether or not the clipboard contains text. Yes, I know there are other ways to do that, but it demonstrates the article simply!

Initialising dynamic arrays

When writing some unit tests a while ago I found myself needing to initialise some dynamic arrays with test data. It would be nice if we could do something like this: var A : array of Integer ; begin A := ( 1 , 2 , 3 , 4 ) ; // !! WRONG end ; but we can't. So I decided to write some functions to initialise dynamic arrays to the contents of another array, be it a constant, a literal or another dynamic array. The result was a set of overloaded routines, one for each data type I needed to handle, for example for Integer and string arrays I had: function CloneArray ( const A : array of Integer ) : TIntegerDynArray ; overload ; var Idx : Integer ; begin SetLength ( Result , Length ( A ) ) ; for Idx := Low ( A ) to High ( A ) do Result [ Idx - Low ( A ) ] := A [ Idx ] ; end ; function CloneArray ( const A : array of string ) : TStringDynArray ; overload ; var Idx : Integer ; begin SetLength ( Result , Len...

Deleting elements from a dynamic array

In my blog " Initialising Dynamic Arrays " I mentioned I have been writing some unit tests that needed numerous repetative array initialisation operations. Well, one of the other common operations I found myself writing was the deletion of items from dynamic arrays. So I decided to find a generic way of doing this. Assuming we know the index of the item to be deleted we need the equivalent of Delphi's built-in Delete procedure for strings. If you read the previous post you won't be surprised to learn that I decided to further extend the Generics.Collections.TArray class by adding to the TArrayEx class I introduced there. My first attempt emulates Delphi's Delete procedure by deleting the array element in-place: i.e. it updates the array passed as a parameter. Unsurprisingly the method is called DeleteInPlace . Here's how it goes: type TArrayEx = class ( TArray ) public .. . class procedure DeleteInPlace < T > ( var A : ...

New Array Utilities Library Unit released

Image
Yesterday I added a shiny new unit to the DelphiDabbler Code Library - the Array Utilities Unit . It lives in the ddablib/arrayutils  repo on GitHub. This unit, named DelphiDabbler.Lib.ArrayUtils.pas ,   provides a single "Advanced" record, TArrayUtils , that contains static methods that perform common operations on generic arrays. There are numerous overloaded versions of many of the methods. Every method operates on a given generic array that is passed as a parameter, either as an array of T or a TArray<T> . The unit requires Delphi XE or later. It has been tested with Delphi XE and Delphi 12. The code depends only on the Delphi RTL, so it should work for any platform supported by Delphi and be both VCL and FireMonkey compatible. I've only tested Windows 32 bit and 64 bit targets. There are far too many methods to describe in here, but you can find them all listed and explained in the comprehensive  online documentation . As a taster you'll find Methods that ...
