The author in the work encountered the need to copy, delete and move the directory needs, Delphi itself provides some directory operation functions, but only for the empty directory, the directory with subdirectories, but also powerless.
Using the Win32 API function and structure, and the recursive program design idea, the author realizes the function of copying, deleting and moving any directory (equivalent to the Xcopy, deltree and move commands in
The CompilerVersion constant identifies the internal version number of the Delphi compiler. It is defined in the System unit and may be referenced either in code just as any other constant:If compilerversion = scompilername: = ' Delphi 2009 ';or in conditional compiler expressions:{$if compilerversion >}//Delphi or later {$ifend}Technical CommentsThe CompilerVers

As a rad tool on Windows, Delphi attracts many software companies to develop application-layer software. In addition to the efficiency of rad, the openness of Delphi (open source code, easy to go deep into the underlying layer) makes a lot of developers feel at ease. Delphi, as a 32-bit compiler on an excellent Windows platform, is widely

If you are new to Delphi, you may be most interested in its rich and powerful VCL (visual component library ). It's exciting to simply throw several components into the form and easily create a program with practical value without having to write code. However, VCL is only a small part of Delphi, and
