Once installed, packages are listed in the Registry under HKEY_CURRENT_USER\Software\Borland\Delphi\ Components meant to be used in the IDE can only be installed as a package, ie.
a DPK master file along with one or more PAS files to be compiled into DCUs and aggregated in a single BPL file that will be registered into the IDE.
DPR file), while the forms (windows) are described in files with the DFM extension, ie. Here's a skeleton of a unit: Open a DOS box, compile the program with "dcc32console", and run the compiled as with "console.exe".
In the end, a statically-linked EXE can turn out to be smaller that a bare EXE and external BPLs.
If one of the cells in the array uses a different dimension from the other cells, you'll have to call High(My Array[thiscell]) to get is upper bound.
Here's an example: To deallocate a dynamic array, assign nil to a variable that references the array or pass the variable to Finalize; either of these methods disposes of the array, provided there are no other references to it.
Moving a design package to another host requires copying the following files: BPL, DCP, possibly DCR resources files, hitting the Component Install Packages menu, and clicking on Add.
In addition to individual packages, it is possible to create a package collection (DPC) to make it easier to distribute the different files that make up a package. This type of file requires a Package Collection Editor (PCE), which is a source file used to define a DPC file.
Note that design-time packages and run-time packages are two different beasts: The former adds itself to a palette in the IDE and provides an interface to access its properties, routines, and events; The latter is used by applications that were compiled with run-time packages, ie. Some BPLs are both design-time and run-time, so I guess they have a switch somewhere in the code that lets me act differently depending on the context.
