Have additional events: OnKeyValueChanged, OnButtonClick.
TDBSumList component
This component is intended for totaling sums and amounts of records in a
TDataSet with dynamic changes. Component keeps a list of TDBSum
objects, which contains types of group operations (goSum or goCount)
and name sum field (goCount name of field is unnecessary).
TPrintDBGridEh component
TPrintDBGridEh provides properties and routines for preview and
print of TDBGridEh component with several features:
Ability to expand rows vertically until all text is printed.
Ability to scale grid to fit it to page width.
Ability to print/preview title for grid.

TPreviewBox component
TPreviewBox lets you create a customizable runtime preview.
TPrinterPreview object
TPrinterPreview lets you to record printable data in buffer for following
output them on screen and to printer. TPrinterPreview have all functions and
properties as in TPrinter object. You can use TPrinterPreview object similarly
of TPrinter except some details. In TPrinter Printer.Canvas.Handle and
Printer.Handle is the same but in TPrinterPreview PrinterPreview.Canvas.Handle
represent the metafile in that is recored the data and PrinterPreview.Handle
represent Printer.Handle. That is mean that you have to use
PrinterPreview.Canvas.Handle for draw operation (DrawText, DrawTexteEx, e.t.c.)
and use PrinterPreview.Handle in functions that return information about
printer facilities (GetDeviceCaps, e.t.c.). Global function PrinterPreview
returns default PrinterPreview object and shows data in default preview form.
TDBEditEh component
represents a single or multi-line edit control that can display and edit a field
in a dataset or can works as non data-aware edit control.
TDBDateTimeEditEh component
represents a single-line date or time edit control that can display and edit
a datetime field in a dataset or can works as non data-aware edit control.
TDBComboBoxEh component
represents a single or multi-line edit control that combines an edit box
with a scrollable list and can display and edit a field in a dataset or can
works as non data-aware combo edit control.
TDBNumberEditEh component
represents a single-line number edit control that can display and edit a numeric
field in a dataset or can works as non data-aware edit control.
TPropStorageEh, TIniPropStorageManEh, TRegPropStorageManEh components
Components realize technology to store component properties to/from settings
storage such as ini files, registry etc.

Installation Library
--------------------
1. Delphi 4.x - 7.x:
--------------------
Uninstall previous or evaluation version of EhLib (Old version) from Delphi
IDE. Remove or copy to other directory files of old version to prevent
crossing old and new version of EhLib (Including EhLib.bpl, EhLib.dcp or
EhLibXX.bpl, EhLibXX.dcp files).
Create directory from which you will install EhLib library
('EhLib directory') (for example, C:\Delphi[X]\EhLib).
Copy files from Common and Delphi[X] directories of the EhLib archive
to 'EhLib directory'.
Use "File\Open..." menu item of Delphi IDE to open the runtime package -
EhLibXX.Dpk.
In "Package..." window click "Compile" button to compile the package.
By default Delphi (5, 6 and 7) place compiled EhLibXX.BPL file to the
<Delphi path>\Projects\Bpl directory and this directory already present
in the search PATH. But if you overwrite default BPL directory then you need
put compiled EhLibXX.BPL file into directory that is accessible
through the search PATH (i.e. DOS "PATH" environment variable; for example,
in the Windows\System directory).
Add, (if needed) 'EhLib directory' in Tools->Environment Options->Library->
Library Path.
After compiling run-time package you must install design-time
package DclEhLibXX.BPL into the IDE.
Use "File\Open..." menu item to open design-time package DclEhLibXX.Dpk.
In "Package..." window click "Compile" button to compile the package
and then click "Install" button to register EhLib components on
the component palette.
EhLib components have to appear on 'EhLib' page of components palette.
2. C++Builder 4.x - 6.x:
------------------------
Uninstall previous or evaluation version of EhLib from C++Builder IDE.
Remove or copy to other directory files of old version to prevent
crossing old and new version of EhLib (Including EhLib.bpl, EhLib.bpi or
EhLibB[X].bpl, EhLibB[X].bpi files).
Create directory from which you will install EhLib library
('EhLib directory') (for example, C:\CBuilder[X]\EhLib).
