Support for C++ development of plugins is implemented

Added PluginReg.cpp and PluginReg.h to support C++ development of Geoblock's plugins for the problem task multipage dialog. Localazation with gnugettext.hpp is included. After making a plugin project new *.gpl file is placed in ..Geoblock/Plugin directory and when runing Geoblock you could find it with icons in Analysis|Problem book multipage dialog. To localize plugins for example into russian or spanish languages, please, unzip LOCALE with translation MO files into the same ..Geoblock/Plugins subdirectory. The sample source codes to develop plugins under Borland C++ Builder are in Extract the archive and add project files with cpp, hpp and obj to Geoblock folders as pointed in the unziped structure. Use Borland C++ Builder 6 or Turbo C++ 2006 to recompile and make HydroReservesPlugin.gpl written in C++ language.

Finally Geoblock received GNU internationalization tools

Finally Geoblock have received an excellent cross-platform GNU internationalization toolkit from Thanks to Lars Dybdahl and Peter Thornqvist for their utils that helped to translate GUI from English into Russian language and localize the program. Instead of 1.5Mb Geoblock.rus that was created by resource dll master with Delphis ITE now we have only 86Kb dictionary file. Because of right organization in form inheritance of the project it was possible to include into source codes only a pair lines with procedures from dxgettext unit to get full translation of GUI. Now the single Geoblock.xml file can be used as the language repository dictionary for updates and exchanges between different translators into other languages.

Source codes with project files for v. 1.5.3 updated

Source codes with Delphi7 project files and the system directory tree were updated and added to download section to help compilation of the Geoblock project group.

Posted by Pavel Vassiliev 2003-03-18

New zips are added to the release 1.5.3.

In addition to previous you will find a and archives in downloaded area of SF. Change old files in your Geoblock's bin directory with new ones from Fixed some minor bugs, the help system is expanded.
Note: this release still works not stable and can be used only like demo program.

Explanation. When the project started as Open Source it was not philanthropy but an attempt to find associate specialists for the software development. Unfortunately hitherto all organizations mentioned earlier like partners help only with unfounded expectancies so the list of partners now is obsolete. The only sponsorship from Getos Ltd. was almost exhausted and the development of the project will conduct henceforth from a face of Geoblock Inc. by hope of feasible cash receipts from clients for further improvements in codes. For more information, please, contact with admin of the project.

The new release 1.5.3 of Geoblock program for 3D modeling and visualization of geoscience datasets, geological exploration, ore reserve calculation and mine planning is issued.

The package has an installation zip archive with executable program and auxiliary files compiled under Delphi 7 Studio. Now the main form has a new Action Manager to centralize events and customize GUI for XP Windows users. Removed all obsolete procedures of captions/hints translation from English into foreign languages for the sake of standard internationalization approach with usage of resource files and only one repository dictionary. Developers and volunteers are invited to improve further functionality of the system and its expansion. All testers would be gratefully appreciated.

Hierarchy of Geoblock Forms Is Improved

The InitialForm as the principal ancestor for all Geoblock hierarchy of inherited forms is designed and commited. Now this unit includes an advanced mechanism for translation visual component captions and hints in graphic user interface and radically simplifies localization of the program with different natural languages.
The programming work on replacement BDE with dbExpress (and IBX) support and migrating Paradox to InterBase tables for Geoblock databases is going on.

First Phase in Conversion of GB Code to D6/Kylix is Finished

All forms, files and resources of the Geoblock project are corrected for using within Delphi 6/Kylix and may be found in CVS repository at
I have no time and possibilities to maintain old versions of Borland Delphi, so from now only the latest version will be supported. Now you can download CVS updated files and build the Geoblock executable application only with Delphi 6, Enterprise Edition, compiler.
Note: You should also use the latest CVS version of GLScene library from to link with, although it is not working still in Geoblock GeoScene window properly

To Run Geoblock Users Need BDE Installed On Their Computers

The execution of many Geoblock’s functions in release 1.5.2 for access to database tables requires Borland Database Engine (BDE). Therefore to run the program downloaded from SF.NET in will need BDE installed on user’s computers.
Upgrading from VCL of D5 onto usage the cross-platform library CLX of D6 means that for running the Geoblock program release 1.5.3 it’s also necessary to have on user’s computer the re-distributable qtintf.dll file.
Note:I’m scheduling to issue the new release 1.5.3 with updated zipped files until the end of the year.
