Delphi uses the Object Pascal and Visual Control Library (VCL) to encapsulate the underlying Windows APIs perfectly, so there is little need to use the underlying Pascal language to build Windows applications or call Windows API functions directly. However, if there is a special situation, VCL does not support, Delphi programmers have to directly face the Windows programming. However, only in extremely spec

Delphi's component reading and writing mechanism (i.)I. Introduction to streaming objects (stream) and read-write objects (Filer)Object-based data management plays an important role in object-oriented programming. In Delphi, the way to support the object-type data management is one of its main features.Delphi is an integrated development environment that combines object-oriented visual design with object-oriented language. The core of

Delphi can not develop Windows driver (here the driver of course not refers to the VxD ^_^) has been the majority of Delphi fans concerned about the issue. Let's not say we can or can't, we'll start by looking at the technical issues that need to be solved to develop a driver with Delphi.Delphi's linker is unable to generate Windows kernel-mode programs, so the driver cannot be generated directly with

Indeed, the combination of several controls plus a few statements may

In-depth windows core programming in Delphi (Appendix A Delphi compilation instructions) Delphi's quick and high compiler mainly comes from the rigor of Object Pascal.
