Try

CString strMyInt ( "123");
int nMyInt;
char* pc;

nMyInt = (int) strtol ( (LPCTSTR) strMyInt, &pc, 10);

if ( *pc)
{
// error
}

Ooops - to elaborate a bit on 'strtol()'
--> begin quote

long strtol( const char *nptr, char **endptr, int base );

The strtol function converts nptr to a long. strtol stops reading the string nptr at the first character it cannot recognize as part of a number. This may be the terminating null character, or it may be the first numeric character greater than or equal to base.
