China DOS Union

Dear all experts and moderators:

I have just developed a monitoring and control system for medical equipment using C/C++, and it has been completed in communication with NAIS's FP0. Now it is about to be delivered. I must remove the logic locks and related functions for preventing long-term use in the program, but I am worried about unlimited copying by customers. Please give me some advice, everyone. Currently, I know two schemes that can be implemented:

1: Read the serial number of the CPU or the CPU of the acquisition card, but I don't know how to read this serial number in C language.
2: Add a hardware dongle, but I haven't actually operated it, and I don't know the price and performance.

If the first scheme can be adopted, it is better; otherwise, I have to add a dongle. Actually, I don't want to do this.

I am originally kind, but I didn't expect the world to be difficult. Now my colleague and I have been working for nearly three months without any income.

Urgent! Urgent! Urgent!...

You can use hardware code encryption methods to prevent users from copying the program indefinitely. If the user copies the program to another machine, because the hardware code changes, the program will not run. In this way, authorized users can use it for a long time and prevent the occurrence of piracy. Many shareware popular on the Internet use this method.

You can calculate this hardware code using the hard disk serial number. Specifically, I will send you the C program code. Please send an email to my mailbox.

Thanks kinglion, I can only do this through the physical serial number of the hard drive now. I sent a C language source program to your two email boxes, please check. Currently, I can read it out, but I can't verify whether what I read is correct. I also hope to get a copy of your original code, thanks.

In the other post you made, I've already uploaded the program. Please take a look.

Thanks KINGLION, I have seen it.

Thanks KINGLION, I have seen it

In addition, may I ask where to download C's *.CHR files? Actually, in my opinion, TC/BC and so on can already meet most engineering requirements - real-time performance, operability to hardware, low requirements for the system, and stability determine that TC/BC still has strong vitality (including DOS). But because TC/BC was launched earlier, it cannot support many hardware - for example, in terms of the display, it cannot well support 800X600 or 1024X768, 256S colors, etc. (need to develop from the bottom layer again).

1: I am now looking for English font files download under TC/BC (to avoid making the programs written be easily recognized as software under DOS at a glance). I don't know which DX can provide relevant download addresses.
2: I am also looking for relevant materials of the interrupt encyclopedia under DOS. Many addresses on the Internet cannot be downloaded. I hope to get some pointers.

Please send me a program to read the physical hard disk serial number under DOS too, thanks!

I'm also looking for it. Send me one.

There is no physical serial number for the electronic disk. You can read the track number and sector number of a specific file to achieve the same purpose (haven't heard of it, right). Guess whether this software is for DOS or WINDOWS http://zk888.go.nease.net

Install a UNIX system. Just use more /pro/cpuinfo.

I have quite a few font files *.CHR for TC. If you need them, leave a message for me at http://zjp-vlk.vicp.net/bbs/

The encryption method of UCDOS is to use the hardware code encryption method to prevent users from copying the program without limitation.

In the industrial control field, real-time performance is the most important, but Windows is not real-time. For the situation that requires both "interface" and "real-time", you can download the "WinSail" software for free under the web page "WWW.FirstSail.b2b.Cn". It can be said that DOS + WinSail = Windows CE. Now, a "WinSail Industrial Control Development System" is widely used in the industry. Its launch truly enables designers not to spend too much time on hardware, underlying operations, interface, parameter settings, etc. when developing products for embedded PCs. They only need to focus on function development. As long as you understand C++ For DOS or Visual C++, you can program under DOS and generate an application system comparable to Windows! The "WinSail Industrial Control Development System" is a software development kit developed based on the DOS system using Borland C++ 3.1 language in Large mode. Although the complete software package is about 450K, the programs generated under DOS have the same interface as WIN9x, with interface elements such as Group, Label, Edit, ComboBox, Button, Radio, Check, ListBox, Grid, ScrollBar, Desktop, ToolsBar, StatusBar, Menu, PopuMenu, Window, Dialog, ICON, Bitmap, oscilloscope, etc. It supports the mouse, and 99.9% of the control operations are compatible with Windows! It can load and run script dialog boxes; supports Socket socket programming; the smallest application with a complete window graphical interface is about 150K and can run in an electronic disk with only 1M; has a delay function with an accuracy of 0.5 microseconds. It can be said that DOS + WinSail >= Windows CE. The "WinSail Industrial Control Development System" currently supports: (1) The API of "WinSail" coexists with the "C++ For DOS" function library, especially coexists with the graphics function BGI of the C language. (2) Supports prioritized multitasking, and can reach up to 50 tasks. (Note: The script file can be configured to not need multitasking support, so that the program runs in single-task.) (3) Supports databases, and the generated files are compatible with Foxpro 2.6 libraries and can be directly opened in Microsoft Office's Excel. (4) Uses 16*16 simplified and traditional Chinese character libraries, 8*16 English character library, and supports TrueType character libraries. (5) The "dialog box" can be pre-made in Visual C++, and then through the conversion software, the Windows dialog box interface can be turned into the interface code source file or script file of the "WinSail" system, making full use of the superiority of Visual, so that the application program interface development on the DOS platform "is no longer difficult"!!!!! (6) Supports multiple resolutions such as 600*480*16, 600*400*256, 800*600*256, 1024*768*256. (7) Supports interface elements such as Group, Label, Edit, ComboBox, Button, Radio, Check, ListBox, Grid, ScrollBar, Desktop, ToolsBar, StatusBar, Menu, PopuMenu, Window, Dialog, ICON, Bitmap, MessageBox, oscilloscope, multi-ordinate oscilloscope, etc. (8) Supports memory access of extended memory - XMS, expanded memory EMS. (9) Supports reading and writing of text registry - INI files, and when writing key values, the "comment content" after the key values can still remain. (10) Supports object-oriented I/O access, shielding the underlying I/O ports. (11) Has a COMM port communication interface, supports multiple parity bits, including "no parity bit", "odd parity bit", "even parity bit", "parity bit always 1", "parity bit always 0". The latter two parity methods are mostly used to distinguish "address" and "data" in multi-machine communication. (12) Supports barcode display. Including EAN_8, UPC_A, UPC_E, EAN_13 (product code), ISBN, ISSN, 39, 128, Codabar, cross 25 code. (13) The window supports multiple callback functions such as "virtual keyboard defined by I/O port", "window timer", "call a function when idle", "call a function when the window is refreshed". (14) Multiple common mathematical operations, including the generation of low-pass, high-pass, band-pass, band-stop filter coefficients (can add rectangular window, triangular window, Hamming window, Hanning window, Blackman window, Sin(x)/x window, cosine window, Kaiser window), filtering, interpolation, fitting, calculus, correlation analysis, FFT, DFT, etc. (15) Statistical process SPC and histogram, measurement reliability and repeatability GageR&R report. (16) Supports display of "Bitmap", "ICON" image files and playback of "Wav" sound files. (17) Supports "ordinary oscilloscope" and "multi-ordinate oscilloscope". (18) Supports Socket socket programming. I.
