Delphi取硬盘特征字

     这2天没更新什么Delphi的博客,原因是F41的笔记本换成用Z500的笔记本上写程序 但是Z500的机器有个问题 F1到F12只有按住FN功能才是F1-F12,所以很不好调试,没办法,自己写了一个改键工具,需要的时候把F1-F9换成1-9.

    现在的Delphi的方向是,把自己的常用和有用的函数封装成Delphi一个单元,以后方便调用.这2天封装了一个函数,易语言的取硬盘特征字,关键API是DeviceIoControl CreateFileA CloseHandle 部分关键代码如下

if j_stOutBuffer.bIDEDeviceMap>0 then
           begin
              j_stInBuffer.cBufferSize:= 512;
              j_stInBuffer.bSectorCountReg := 1;
              j_stInBuffer.bSectorNumberReg := 1;
              j_stInBuffer.bDriveHeadReg := 160;
              j_stInBuffer.bCommandReg:= j_stOutBuffer.bIDEDeviceMap;
              if j_stInBuffer.bCommandReg =0 then
              begin
                  j_stInBuffer.bCommandReg :=161;
              end;
              if j_stInBuffer.bCommandReg <>0 then
              begin
                  j_stInBuffer.bCommandReg :=236;
              end;
              myDeviceIoContro2 (j_h, 508040, j_stInBuffer, 32,
              j_OutBuffer2, 544, j_ls, 0);

             end;

这里自己自己初步找了一个貌似比较合适自己的Delphi命名规则:(g_ 全局变量前缀,b_ 程序集变量前缀,j_ 局部变量前缀 h表示句柄lp表示指针st表示结构sz表示字符串 dw表示整型 fl表示小数)

命令规则:作用域_形容+名字
