| 3 | * tstVBoxAPIWin - sample program to illustrate the VirtualBox
|
|---|
| 4 | * COM API for machine management on Windows.
|
|---|
| 5 | It only uses standard C/C++ and COM semantics,
|
|---|
| 6 | * no additional VBox classes/macros/helpers. To
|
|---|
| 7 | * make things even easier to follow, only the
|
|---|
| 8 | * standard Win32 API has been used. Typically,
|
|---|
| 9 | * C++ developers would make use of Microsoft's
|
|---|
| 10 | * ATL to ease development.
