When using VC + + to write a DLL for PowerBuilder, pay attention to the following 2 points: calling convention C + + functions have _stdcall, _cdecl, _fastcall, and many other calling conventions, the calling convention is used to describe the order of the stack of function parameters and who (the function itself or the caller) to modify the stack.When you write a DLL for a PB call, you use the _stdcall calling convention, as follows: extern "C" _dec

PowerBuilder (PB) is a powerful development tool based on client/server architecture launched by PowerSoft Company (has been acquired by Sybase) and has been well received by developers since its inception. DataWindow is a patented technology in PB control, its data processing method is quite concise, data window can handle a variety of display formats, report printing, the same deal with complex nested reports freely. The processing mechanism of a d

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

that may occur during communication, this allows you to use it to create full-duplex event-driven communications. Program . The MSComm control provides two communication methods: event-driven and query. The query method checks the commevent attribute values to determine communication events and errors. When the serial port receives or sends a specified amount of data or the status changes, the MSComm communication control captures these events and errors to trigger the oncomm event, check the

No matter how many years you have used a tool and how many books you have written, the technology is changing with each passing day. I think everyone is on the starting line. The most common is for beginners. When they see a new technology, they will come to the competition. PK is never concluded. Existence is truth. Petabytes can do a lot of things, and there are still so many brothers using them. There is a truth about his existence. The future demand is in the Spring and Autumn Periods and th

Transaction Object We know that transaction objects play a very important role in the power BUILDER, and the power BUILDER applications must be connected to various databases through transaction objects, so before we discuss the relationship between data windows and databases, we first introduce the basics of objects. In power builder, to operate on a database, you must first establish a connection to the database. In a Power builder database connection, a transaction object is a special, Non-

Today's introduction to how PB connects SQL through a data source1. First to create a new data source, see the previous blog2. Locate oDB ODBC and select New profile3. Fill in the Profile name, select the data source we built, fill in the SQL connection user name and password4. Select the Preview tab, copy the database connection string and paste it into the application Open event5. Click OK6. Select the data source we built, click ConnectPowerBuilder
