Windows Virtual PC Interfaces

[Windows Virtual PC is no longer available for use as of Windows 8. Instead, use the Hyper-V WMI provider (V2).]

The following interfaces are supported by Windows Virtual PC.

IVMDVDDriveCollection	Defines the collection of CD and DVD drives within the VM.
IVMDVDDriveEvents	Defines the outgoing event interface for the IVMDVDDrive interface.
IVMFloppyDrive	Controls a floppy drive within a VM.
IVMFloppyDriveCollection	Defines a collection of floppy drives within the VM.
IVMFloppyDriveEvents	Defines the outgoing event interface for the IVMFloppyDrive interface.
IVMGuestOS	Defines the guest operating system running inside a VM.
IVMHardDisk	Provides access to a hard disk image.
IVMHardDiskConnection	Defines the connection for a hard disk within the VM.
IVMHardDiskConnectionCollection	Defines the collection of hard disk connections within the VM.
IVMHostInfo	Retrieves information about the host machine.

Note for developers on 64-bit Windows

On 64-bit editions of Windows, the type library for Windows Virtual PC is in a 64-bit binary (VPC.exe) in the %WinDir%\System32 directory. That directory is not visible by default to 32-bit processes; WOW64 maps all access to the %WinDir%\System32 directory to the %WinDir%\SysWOW64 directory by default. Visual Studio is a 32-bit binary and therefore cannot open the file in this location. To generate an interoperability assembly for Windows Virtual PC, use TlbImp.exe, which comes with Visual Studio and the Windows SDK. To generate Microsoft.VirtualPC.Interop.dll, use the following command line:

**TlbImp.exe /out:**Microsoft.VirtualPC.Interop.dll /namespace:Microsoft.VirtualPC.Interop %WinDir%\System32\VPC.exe

Other solutions include copying VPC.exe to a different directory where the compiler can find it, or using the OleView.exe tool from the Windows SDK to extract an .idl file from the type library in VPC.exe.
