C++ NXT Bluetooth Library

[salgfrancisco]

I was wondering if anyone had successfully set up this library http://www.norgesgade14.dk/bluetoothlibrary.php in Visual Studio or Visual c++ Express. I have already used NXT++ with no problems however it lacks a lot of features.
It only mentions we need to add the files to our project, however it keeps returning different errors.
Could anyone provide a step-by-step guide on how to use it?

1. Download and extract
2. make a VC++ project
3. See my post here: https://sourceforge.net/apps/phpbb/mind ... ffel#p7160
4. Build

Ok, so i added the files to the project I created, but when compiling I get these errors:

]1>------ Build started: Project: NXT library, Configuration: Debug Win32 ------
1>Compiling...

1>c:\nxt c++ bluetooth library\bluetooth.cpp(42) : error C2664: 'CreateFileW' : cannot convert parameter 1 from 'const char *' to 'LPCWSTR'

Any ideas how to solve them?

Use a cast to convert the char* to LPCWSTR
For the other error, is nxt.h in the same directory as main.cpp?
If not, add the folder to the VC++ include path.

Use a cast to convert the char* to LPCWSTR

That's not a good idea if it really is a char pointer. Either change the project to compile as ANSI instead of Unicode, or change the call to CreateFile() to use CreateFileA().
