代码说明:

调用windows的dl文件,获取u盘在pc上的盘符,然后向u盘中拷贝文件。 源方法如下。 判断指定驱动器的类型:GetDriveTypeA函数 该函数能依据根目录识别1个驱动器是软驱或光驱或硬盘等。声明: Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long 参数nDrive:驱动器根目录路径的字符串,如"C : ". 函数返回值为1个常数,指定驱动器类型:DRIVE_ REMOVABLE=2,软驱; REMOVABLE是可移动的 如果驱动器不能识别,则返回0,如指定目录不 DRIVE_ FIXED=3,硬盘。 存在,则返回1。 DRIVE _REMOTE=4,网络驱动器; DRIVE _CDROM=5,光驱; DRIVE_ RAMDISK=6虚拟磁盘  调用如: Private Const DRIVE_CDROM = 5

  • 混音程序
    用C++编写的两路音频混音程序,很适合初学者。 Mixer.dsp     This file (the project file) contains information at the project level and     is used to build a single project or subproject. Other users can share the     project (.dsp) file, but they should export the makefiles locally. Mixer.h     This is the main header file for the application.  It includes other     project specific headers (including Resource.h) and declares the     CMixerApp application class. Mixer.cpp     This is the main application source file that contains the application     class CMixerApp.
