I'm using Visual Studio Ultimate 2012 with C++ CLR Console Application.
This is the Compiler error message:
1>------ Build started: Project: ConsoleApplication1, Configuration: Debug Win32 ------
1>ConsoleApplication1.obj : error LNK2028: unresolved token (0A000102) "extern "C" int __stdcall McOpenDriver(char const *)" (?McOpenDriver@@$$J14YGHPBD@Z) referenced in function "int __cdecl main(int,char * * const)" (?main@@$$HYAHHQAPAD@Z)

This error indicated that the compiler need to linked the program with the necessary windows library. The program cannot execute "extern "C" int __stdcall McOpenDriver(char const *)" because this is an extern C command and need to be linked with the imported library, in this case I'll using "multicam.lib" library.
Select from the menu: "Project -> Properties " ( Alt+F7 )
In the property pages in the tree on the left select: Configuration Properties -> Linker -> Input
In the right hand pane check: Additional Dependencies
It should contain these library already:
- kernel32.lib
- user32.lib
- gdi32.lib
- winspool.lib
- comdlg32.lib
- advapi32.lib
- shell32.lib
- ole32.lib
- oleaut32.lib
- uuid.lib
- odbc32.lib
- odbccp32.lib
Now fill the " Additional Dependencies" tab with the required library:
multicam.lib; %(AdditionalDependencies)
