Description
Using the Sample
Key Project Files
Technologies Demonstrated
This sample shows the native interface of the Microsoft virtual machine, native code operations that are garbage-collector safe, and native methods which encapsulate several Win32 functions (CreateEvent, PulseEvent, CloseHandle). The provided methods are implemented in a dynamic-link library (DLL). Various methods and variables are accessed from native code.
To compile the sample
Use Nmake.exe to compile the makefile in the \Samples\Native\Native_raw directory. Type the following command:
Nmake
To run the sample
Run Go.bat in the \Samples\Native\Native_raw directory.
This displays the following output in the console window:
