For example, 2 Data Pipeline user objectNew-> Pb object-> standard class-> OK-> select pipeline-> OK Attribute:Dataobject: Specifies which data pipeline to useThis attribute is the most important attribute of a Data Pipeline. It is similar to the dataobject attribute of a Data Form Control. This attribute can only be set dur

Two tips for window operations in Pb Xin Xiaohui Powerbuilder is an application development tool with comprehensive functions and excellent performance. However, it is also a complex system with a complex structure. It is difficult to learn and master it. In my practical work, I have summarized the two window operation skills and shared them with you. 1. Find the data that matches the input data in the drop-down data window. When we look for data fro

Importing and exporting the DW in PB is really easy to use. After nearly a week of exploration, although I have not fully understood all the functions of DW settings for XML templates, It is enough for me to use. DW Import and Export XML, you can create an XML template in the design of the DW canvas, a DW can set multiple different XML templates, that is, you can set different templates for the export or import. A template can be saved as another temp

The binfile format is a Pb-compiled image file, which is generally provided in both binfile and nb0 file formats. The nb0 file is a complete image file in the address space, which is equivalent to a hard copy of the address space. The binfile is a binary ROM image file format. It compresses invalid data compared with the nb0 file. The binfile contains the file header and many segments. Each segment provides the first address, length, verification code

relational databases, Sybase and Microsoft SQL server support the use of timestamps. In PowerBuilder, no matter which database the user is connected to in the background, Pb will automatically ignore the update characteristics option as long as the column name with timestamp in the table and the data type is datetime, the where clause generates a comparison between the primary key and the timestamp column. If your database does not support timestam

The author needs to process the DBF file data when developing an application system. In Pb, only the data formats of dbaseii and dbaseiii are supported, and the updated version is not supported. Therefore, you need to program your own processing. During programming, you may encounter read/write operations on binary files. For example, read files in the following format by byte and convert them to decimal characters. AA 00 56 00 bb cc dd ee ff ......

Author: Xingda Computer technology company (www.study01job.com) Guo Baoli The query program is an indispensable piece of functionality when we develop the application software project. So, here I prepare the system to summarize the query program's writing. First of all, introduce the common query technology, in the following article I will have a choice to give an example. I hope the article here for everyone's development has a relatively large practical value.

This paper mainly introduces how to make fuzzy query of data window according to the fields in the Data window in PB. The code examples for this system are demonstrated using power Builder6.5. Code and Design: 1. Create a new window, named W_query. Put a data window control in the window, named Dw_master. Put a data window in the Dw_master, and place a button named Cb_query. See figure below: 2. A new structure (structure) is named Str_result_colum
