Delphi

Say in front I remember the first time I contacted COM component programming, there is the question: there is no good way to pass the dataset. We know that Visual FoxPro is the most powerful data processing system, and its cursor strong, flexible support is unmatched. Since Visual FoxPro is so powerful at data set processing, COM programming, how to simply in various types of client programs and Visual Fox

There are articles about the implementation of common DLL plug-ins in the VC knowledge base, but this method is not used in many large software (such as ArcGIS and office, com-based plug-ins are widely used in today's large-scale software. 2. Implementing plug-ins is inseparable from three elements Plug-in Manager (that is, the main program to use these plug-ins) The basic interface of the plug-in (that i

change accordingly. This requirement for isolating the customer and component implementation imposes the following restrictions on the component: the component must encapsulate the language used for its implementation; the component must be released in binary form; components must be upgraded without interrupting old customers; components on the network must be freely allocated; Sancom As the saying goes, "No rule, no square", components that divide applications into multiple parts also need to

Php calls the implementation code of components through the COM class. In PHP4.2.0 to 4.2.3, you can use the w32api_register_function to call an external DLL, provided that you need to open the extended php_w32api.dll in php. ini. If you are using PHP5, you can use the w32api_register_function function in PHP 4.2.0 to call an external DLL, provided that you need to open the extended php_w32api.dll in php. ini.
