CTab32 - Italian corporate accounting

CTab32 V.070 release 30.0:

This is a program to record the money movements of one or more companies in double entry, without memory limits and also record their balance sheet, any deficit, VAT input, VAT output, etc. ( with numbered and non-numbered accounts reference code, etc.).

Unfortunately it is incomplete, but the project can be continued by others who purchase it (I have reached 70% of the development, but I have other projects for now).

Here you will find all the sourcecode of the latest versions of the Delphi libraries designed and created solely by me in recent years and others created in 2023 and all the project files with extensive internal documentation (in Italian).

I have incorporated an ms-dos style text mode emulator, invented by me, also with all the sourcecode, but rest assured: CTab32 is not a 16-bit program, but a 32-64 bit one compiled under Windows 10 and written in Assembly protected mode, with object-oriented programming.

I've incorporated an efficient keyboard manager, with auto-repeatition of keys pushed and other retro-style features.

The mouse can also be used, for now only in a few cases:

if the main form loses focus the keyboard can be reset with a mouse click on the background of this application or if the user want to show the notice box, for release, version and author informations, or want to print the companies money movements log file (double entry).

For these reasons there is avalaible both a free demo thanthe complete project which, in my opinion, has a fair price, but could be higher than usual. 2 of us worked on it (Maurilio Di Pietro, for the accounting formulas and the idea plus support and I did everything else) for 5 months.

System requirements

This app run on all machines with operating systems from Windows XP to Windows 11 . As far as hardware is concerned, all AMD and Intel microprocessors that support 32-bit protected mode, which have a clock frequency of no less than 667 MHZ and which have at least 1 GB of RAM installed are supported.

Description of operation and warranty:

My programs are distributed in 2 versions: zip archive generated with WinRAR (*) and installer created with Inno Setup Compiler (**); they do not contain advertising, there are no pop-ups of any kind, you do not have to pay to win, they do not connect in any way to the internet, they do not install or modify any DLL (dynamic linked libraries), all the files used by my applications are were created solely by me (***) and are transferred to a single destination folder. My program never accesses files outside the folder to which it was transferred, with the exception, only for some programs, of a configuration subfolder of the root directory of your hard disk/SD, created specifically to contain temporary files and preferences.

The installation program will only take care of selecting the destination, transferring files, creating an icon in the programs section of the start menu, optionally creating an icon on the desktop and configuring the new file extensions, defined by me, in such way that, doing a double click on one of them, he is load it into memory, to be able to modify it.

In Windows 10 or Windows 11 it is not recommended to install this software in the "Program files" and "Program files (x86)" folders, because, if you do not run this software, after the installation process, with administrator privilege, is impossible to save the configuration file, the top players score table file and the game recording file. The suggestion is to select a subfolder of the main folder of your hard disk/SD as the destination folder during the installation process.

My programs were conceived, designed and developed solely by me, in Assembly (80386+ protected mode) and Pascal through the Borland Delphi 7.0 development system. They run on all machines with operating systems from Windows XP to Windows 11 and numerous tests have been carried out by me on various PCs, periodically releasing updates to correct any bugs and expand their features.

As far as hardware is concerned, all AMD and Intel microprocessors that support 32-bit protected mode, which have a clock frequency of no less than 667 MHZ and which have at least 1 GB of RAM installed are supported. As regards the memory occupation on the hard disk or SD card, it is almost always around 50 MB to 100 MB with the exception of "my 5 video games" (500MB).

I have also created, designed and developed some software that is not compatible with operating systems superior to Windows XP, always explaining the hardware/software requirements, in Assembly (80x86+ real mode) and Pascal through the Borland Pascal 1.0 development system. They run on all machines with operating systems from Windows 2000 to Windows XP or on machines with the latest Windows systems equipped with an emulator.

As far as hardware is concerned, all AMD and Intel microprocessors are supported that support 16/20 bit real mode, that have a clock frequency of no less than 667 MHZ, that have at least 600 KB of free conventional RAM. The PC must has a VGA graphics card or MCGA compatible or emulated. As regards the memory occupation on the hard disk or SD card, it is almost always between 5 MB and 15 MB.

All my programs have dedicated software of my own invention for managing peripherals, such as the video card, sound card, keyboard and mouse; furthermore they are made up of a single thread with polling technology which sorts the various phases of the process progress based on various indices and according to certain events. it is modular software, so even if there is only one thread there are methods called by it that behave like other threads and contribute to the progress of portions of the process.

Windows 10 and Windows 11 messages such as "This file may be dangerous", "author unknown" or "The file is suspicious. Virus scanning. The file has been sent to the analysis department, please wait... The file appears safe", they are warnings that can be displayed the first time my software is run and which depend on a priori protection mechanisms by the operating system and antivirus manufacturers, but above all on the unusual structure of my programs published here.

(*) the latest version of WinRAR was mainly used, but in older programs it is possible that previous versions are still used.

(**) the Inno Setup Compiler 6.2.0 (a) version was mainly used, but in older programs the Inno Setup Compiler 5.5.1 (a) version may still be used.

(***) except for most .WAV file(s) which not contain more than the first 30 seconds of music from other sources (old Commodore 64 soundtracks, copyright-free files converted from MIDI, but also author's music: only the first 30 seconds of the instrumental part of the song). Some cover images and other images in the devlog sections were not entirely created by me but from images downloaded from the Internet and modified.

Messages from Windows 10, Windows 11 and some antiviruses (Avast):

Such notifications or warnings may be displayed, not for all versions of Windows and installed antivirus programs, during installation via the setup file or when first running the game or utility of a newly purchased or free downloaded .ZIP archive.

"This file may be dangerous": generic message that considers any executable file or archive containing some and coming from the Internet as a dangerous file that should not be installed.

"Author unknown": message that simply warns that the (c) CopyRight international registration has not been carried out and that the software does not come from a recognized software house.

Although this is authentic software, developed entirely by me, not having enough money to invest for copyright registration, this should be normal; with all the software developers in the world I don't think they all have had this opportunity.

"Allow the running app to make changes to your computer?" is a generic message that simply indicates that a "setup" executable file has been opened.

"The file is suspicious. Antivirus analysis. The file has been sent to the analysis department, please wait... The file seems safe": Some antiviruses, given the somewhat unusual structure of my games (screensaver style), notice that they not appear to have any interaction with the user, since they do not use default methods of accessing devices, and note that the behavior is similar to that of some computer viruses running in the background. In any case, I am not a hacker nor have I ever thought of causing damage, nor of stealing information or stealing money, nor of decoding or deprotecting other people's programs, nor of developing harmful software, much less viruses; any check for malware or viruses in my programs will result as clean.
