Whether it is a. Net-based WebService developed by Vs, a WebService developed by Java, or a. Net developed by petabytes.The principles of WebService calling by web service and Pb are the same, and WebServices are accessed through WSDL. The specific steps are as follows: 1. Compile WebService 2. Create a PB Web Service Proxy 3. Create Pb web service client 1. Comp

There are many forms in PB (PowerBuilder), which are not called forms, and they have a different McCartney: Artboards. As the name implies, the artboard is to let you draw, haha, open a joke. Below, a brief introduction to some of the commonly used artboards: Apply Object Brush (Applicationpainter) Apply an object brush to create an App object and a library that holds all of the application's objects. The Application object defines the execution envi

---- When the data window of continuous paper printing is used, the page length needs to be customized to ensure that the printer runs correctly without manual intervention to achieve continuous printing. In PB, an external function must be called to customize the paper length, which is cumbersome. This article introduces a method to directly control the printer and easily set the page length. ---- I,Prerequisites ---- The communication between the

"locking a column with Pb when the data window is horizontally rolled" -------------------------------------------------------------------------------- Zhang Hongwei, Research Office of data knowledge engineering, computer department, Chongqing University (400044), question proposal The article "locking a column with petabytes during horizontal scrolling of data windows" of H23, 39th tells you how to implement data windows. A method used to lock a

Describe, Evaluatate, and LookUpDisplay in PB (powerbuilder) Describe can Describe the value of a property of an object in DW, although the function Describe can obtain the object's InformationBut the value of the expression cannot be read normally.Evaluate if you want to obtain the value of an expression in a data window object consisting of attributes and functions, you must Describe the function.Use the Evaluate function,The displayed value of Look

I. First, write two functions, namely reading and writing files:Reference to the function of reading and writing files in Pb: http://blog.csdn.net/xys_777/archive/2010/08/04/5787833.aspx Ii. Saving files Li_value = getfileopenname ("select file", ls_docname, ls_named) 3. Open a file // Use selectblob to assign BLOB data to blob variable lb_fj

Chapter 1 General Usage 1. Start of the program and open event of the application. Exit the program routine: (halt is used to exit the function) Int surequit Surequit = 2 Surequit = MessageBox ("Exit System", "confirm that data is saved before exiting", question !, Okcancel !, 2) If surequit = 1 then halt 2. Effective scope of variable definition: ◎ Declare-globe global variable, effective throughout the program ◎ Declare-instance local variable, which can be valid in an object (such as a form

Externally called in PbProgramAnd wait until the program is running. If we want to back up the Adaptive Server Anywhere 6.0 database, after the backup is complete, it will show "The backup is complete! "Prompt information. If a message is displayed immediately after the backup program dbbackup is called with MessageBox, this will happen when the program is running: dbbackup backup is still running." backup is complete! The prompt is displayed, obviously not in line with our ideas. In this case

middle, while the decimal calculation is not added.The following is a detailed list of conversions:The decimal algorithm: 1 kilobyte [KB] = (103) byte 1 megabyte [MB] = 1 (106) byte 1 gigabyte [GB] = 1 (109) byte 1 terabyte [TB] = 1 (1012) byte 1 Petabyte [PB] = 1 (1015) byte 1 Exabyte [EB] = 1 (1018) byte 1 zettabyte [ZB] = 1 for a few (1021) byte 1 yottabyte [YB] = 1 for a few more (102

, the abbreviations are still different. The binary computation adds an I letter in the middle, while the decimal computation does not. The conversion is listed in detail below: Decimal algorithm: 1 kilobyte [KB] = 1000 (103) byte 1 megabyte [MB] = 1 000 000 (106) byte 1 gigabyte [GB] = 1 000 000 000 (109) byte 1 terabyte [TB] = 1 000 000 000 000 (1012) byte 1 petabyte [Pb] = 1 000 000 000 000 000 (10

Storage Capacity Unit: Bit, Byte, KB, MB, GB, TB, PB, EB, ZB, YB, zbyb I recently read the Hadoop authoritative guide book, which has been designed by many organizations, However, my previous books seem to only teach GB, The current textbooks may be terabytes or petabytes of data, but I'm not sure. However, in the near future, there may be larger units that can be used, These days I 've been playing a boring game that tests my brain capacity, and

What is the storage unit of a computer? Computer storage units are generally expressed in bit, Byte, KB, MB, GB, TB, PB, EB, ZB, BB, We often refer to the byte abbreviation as B and ask K for the KB abbreviation. What a few k, what a few B. Two, what is their conversion relationship? 1, the smallest unit in which the computer stores information: bit bit (bit) (Binary Digits): holds a binary number, that is, 0 or 1, the smallest storage unit.

1bit=1 bit 2 binary information 1B (byte byte)1KB (kilobyte KB) =2 (Ten) b=1024b=2 (ten) B;1MB (Megabyte MBytes) =2 (Ten) kb=1024kb=2 B; equivalent to the content of a short story.1GB (Gigabyte gigabytes) =2 (mb=1024mb=2) B; the equivalent of a short story.1TB (Trillionbyte) =2 (gb=1024gb=2) B; equivalent to the music content of Beethoven's fifth movement Symphony.1PB (Petabyte) =2 (tb=1024tb=2) B; the equivalent of all the X-ray picture information i

equals 8 bits (1byte=8bit). Eight-bit binary number minimum is 00000000, the maximum is 11111111; usually 1 bytes can be stored in an ASCII code, 2 bytes can hold a Chinese character GB code.3, the wordWhen a computer is processing data, the length of time it accesses, processes, and transmits is called word. A word is usually made up of one or more bytes (usually the integer bits of bytes). For example, the word 286 microcomputer consists of 2 bytes, its word length is 16;486 microcomputer's w
