Chang,

The example on my website I mentioned in my last message has a VC++ project in the spyin.zip file. You can take a look at it for an example. The TurboC may or may not be easily ported to VC++. The assembler code can be ported with the _asm directive, or just linked from it's obj file if it's 32bit, or you can use MASM but I'm not sure what version of VisualStudio ships with the assembler.
