1. PowerBuilder IntroductionPowerBuilder was a leader in the rapid development platform for Management software in the 1990 's, and was suitable for developing client/server architecture applications based on relational databases. Based on its patented DataWindow technology, PB Development database management software is more than 10 times times more efficient than other development platforms, and its advanced compilers make the program run fast.After

Four buffers of DataWindow In PowerBuilder, DataWindow is the object that the user front-end uses to store and manipulate data. In each DataWindow object, 4 two-dimensional tables are used as data buffers to store the data that is queried. In the DataWindow, the operation of the data processing system in the user is actually the modification and movement of it in these buffers, finally, when the user submits the database, the system forms the SQL in-

Recently, the ghost had the idea of jdbc, because it was necessary to integrate the oracle driver into the software. This is a common problem, but I am not prepared to solve it in a common way. The common method is to get a "simplified" oracle client (you need to write the Registry) or directly connect to the client from oracle (you need to configure the tnsname file) Or simply integrate the oracle odbc driver (requires registration and configuration) I used

I recently wrote a small software program for searching disks. Two problems are found. In the past, DT and DW were used to process a small number of rows of data. It is difficult to find this problem. 1. the array cannot be used to release space. 2. datastore inserts rows (insertrow () at a speed of only 1% of DW When findfirstfile is used, findnextfile puts the file information into a large array. However, after use. Even if you manually

PowerBuilder's Data Window object is its unique intelligent object, its encapsulation is good, the function is formidable, the manifestation form is rich and diverse, for this reason, many MIS developers regard PowerBuilder as the preferred development tool. Under normal circumstances, a data window can only update a database table, but in the MIS development process, we often encounter this situation: a data window by two or more database tables as

PowerBuilder prevents decompilation: pbkiller cannot parse the Longlong type and the error is a mess. Pbkiller2.5.18 cannot parse the Longlong type. Once you declare that the Longlong type cannot be decompiled, the value is incorrect because Longlong uses a pointer-like method to store the value. As long as you write in the Code as follows: Int AAA = 100Long BBB = 1000Longlong CCC = 20000Boolean DDD = falseDatawindow dwx AAA = 2-3Bbb = 1-2CCC = (AAA

Recently, I have access to Pb and started to use pb10. Later I have access to pb8. At that time, I really felt that the vs series development platform was the perfect! But I don't get used to it anymore. I thought it should be a registry problem after suffering from several times of system reinstallation by pb8. Finally, we found a key value that saved the breakpoint information before pb8 went wrong: [HKEY_CURRENT_USER \ Software \ Sybase \ PowerBuilder
