I am migrating my application from .net 2003 to .net 2005 which ahs some code related to RFID Reders in evc++. On complilng the given code I get following error:
error C2440: '=' : cannot convert from 'const char (*)[8]' to 'char *'

the place where i get this error is:
#define VER_PLATFORM_WIN32_CE 3
#define s_VER_PLATFORM_WIN32_CE "CE"

char* pVersion = NULL;
long PlatformID = VersionInformation.dwPlatformId;

switch (PlatformID) {
case VER_PLATFORM_WIN32_CE:
pVersion = &s_VER_PLATFORM_WIN32_CE; //error over here
break;
default:
pVersion = &s_VER_PLATFORM_UNKNOWN; //error over here
}

it looks like you are trying to treat a #define as a variable

pVersion = &s_VER_PLATFORM_WIN32_CE; //error over here
This is invalid. When the compiler sees s_VER_PLATFORM_WIN32_CE, what it will do is replace it with the value you specifed. In this clase it looks like the compiler is putting the value "CE" into a 8 byte character array. To fix it simply remove the '&' infront of s_VER_PLATFOR_WIN32_CE
