Delphi interface to Windows Portable Devices

The use of the Portable Devices interface is demonstrated by a sample program provided by Microsoft at GitHub. The source code is written in C++ and requires Visual Studio. To use the Windows Portable Devices functions under Delphi, it is first necessary to convert the required header files into Delphi units and then to translate the cpp files into pas files.

Console application sample

The sample demonstrates the following tasks using the WPD API:

• Enumerate portable devices
• Enumerate content on a portable device
• Query the capabilities of a portable device
• Read and write properties for content on a portable device
• Transfer content on or off for a portable device
• Register or unregister for portable device events

Files:

• WpdSample.dpr - Sample program

VCL applcation sample:

The Delphi VCL sample demonstrates the following tasks:

• Building a list of available portable devices
• Building a directory tree of the selected portable device
• Selecting a directory and displaying the associated files
• Copying the selected files to a Windows directory

Files:

• PortableCopy.dpr - VCL sample project file
• Unit PortCopyMain.pas - Main unit of sample project
• Form PortCopyMain.dfm - Main form of sample project

Required units:

• Unit IStreamApi.pas - Replaces some declarations in Winapi.ActiveX
• Unit PortableDeviceDefs.pas - Types and constants from PortableDevice.h
• Unit PortableDeviceApi.pas - Delphi interface to Windows Portable Devices
• Unit PortableDeviceUtils.pas - Objects and functions to access Windows Portable Devices
• Unit ExtFileUtils.pas - Type definitions and functions for PortableDeviceUtils.pas
• Unit FileUtils.pas - Type definitions and functions for file processing
