Some errors in VC++

Question

I have a code that generates errors on my PC but does't on other PC.I have windows 7 installed and also installed the compatible SDK for windows 7.I have also included the VC directories (from Tools -> option-> vc Diretories) but still the code generates follwing errors.

error C2059: syntax error : 'constant'
error C2238: unexpected token(s) preceding ';'
error C2589: '(' : illegal token on right side of '::'
warning C4091: '' : ignored on left of 'const unsigned int' when no variable is declared
error C2143: syntax error : missing ';' before '::'
error C2059: syntax error : '::'
error C2059: syntax error : 'constant'
error C2238: unexpected token(s) preceding ';'

statement generating error are as following

static const unsigned int MAPVK_VK_TO_CHAR;
const unsigned int KeyLogger :: MAPVK_VK_TO_CHAR = 0x02;

Answer 1

What's MAPVK_VK_TO_CHAR? I ask because the error might indicate that this is some macro.

Why do you make a plain identifier (not a macro) all caps, anyway? That's just begging for one of the thousands of macros in <windows.h> to trample over it. (Not that not making it all caps would prevent that, since <windows.h> sacrilegiously defines many mixed-case macros...)

Otherwise you would have to paste some minimal, compilable example showing the problem.

Answer 2

Try selecting MAPVK_VK_TO_CHAR and hitting F12 to see if the symbol is declared elsewhere.
