pb petabyte

For projects that are currently developed simultaneously using pb and. NET, if you want to call the functions of. NET under PB, you can only make. NET a COM component and then call it in PB. The method is as follows: 1. Create a class library in. NET Ii. Register a class library 3. Calling in PB The following describes

In the computer newspaper, I saw that ABN Amro's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual 50%~70% growth of storage, So I want to see how big the PB is, and calculate the 27PB size of the hard disk about 400,000 80. 1Byte = 8 Bit (0,1) 1 KB = 1,024 Bytes (size of a shortcut) 1 MB = 1,024 KB = 1,048,576 Bytes (size of one floppy disk) 1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 Bytes (size of an AVI m

1. Introduction In the development of MIS, it is often necessary to get the tree directory structure and corresponding file information in the local computer, such as the choice of the catalogue and the selection of special files, and the PowerBuilder (PB) does not provide a special tree directory object. This requires the developer of the program to implement the appropriate tree directory. In this paper, a method of using pure

Small series here to share a little knowledge about the PB design form, sometimes need to hide some controls. However, when the control is hidden and the program is not running, it will be hidden, so how to find the hidden space. problem For example, a small series makes a small example, hiding a button control Hide Results Solve There are a lot of partners do not seem to have used Pb, and then face this si

The smallest base unit is byte. Not many people do not know, the following first in order to give all units Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, NB I only know the top five, and most people know that, according to the rate of 1024 calculation 40 1tb=2 byte=1099511627776 Byte of the second order 1pb=2 's 50-time Square Byte=1125899906842624byte 60 1eb=2 byte= 1152921504606846976 Byte of the second order 70 1zb=2 byte= 1180591620717411303424 Byte o

[From network] Describes the principles of password encryption and decryption for database connection description files in Pb development environments. Encryption principle: first, convert the original string (reverse), take ASCII characters one by one, convert them from decimal to hexadecimal, and then convert them into lowercase letters, end with '00. Decryption principle: remove the '00' at the end, and convert the original st

In the computer newspaper, the Dutch bank's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual growth of 50%~70% reserves, So want to see how much PB, calculate 27pb about 400,000 80 of the hard disk size. 1Byte = 8 Bit (0,1) 1 KB = 1,024 Bytes (size of a shortcut) 1 MB = 1,024 KB = 1,048,576 Bytes (size of a floppy disk) 1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 Bytes (size of an AVI movie) 1 TB = 1,024 GB

This paper expounds the principle of encrypting and decrypting the database connection description file under PB development environment. Encryption principle: First invert the original string (reverse), one character for ASCII and from 10 to 16 into the value, and then to lowercase, the final end Plus ' 00 ' as a terminator. Decryption principle: Remove the end of ' 00 ', the original string inversion (reverse), every 2 characters from 16 to 10 into

Wire Introduction Lightweight protocol buffers, Java Library for mobile devices (compared to the code generated by PROTOC), the number of code methods generated by wire will be greatly reduced, which will help Android apps avoid limiting the number of 65k methods How to use Download the most recent wire jar package, currently the latest version is Wire-compiler-1.7.0-jar-with-dependencies.jar, with a download link on GitHub Write the. proto file, which is directly used in

When debugging Pb today, an error occurs: 1. Open PbProgramWhen running, the system prompts that an unhandled Win32 exception occurs in pb90.exe, and then enables. Net debugger debugging. Re-open PB or this error, and restarting the computer is no miracle. Is it because my PB crashes and I want to reinstall it. This is a big project. I don't want to reinstall
