You have to specify an actual exported name, not the name that the
precompiler macros create for you.

No.  That would not be possible.  The whole reason for having A and W
versions of any given function in the first place is because LPTSTR and
LPCTSTR parameters are different - char* for Ansi and wchar_t* for Unicode -
depending on whether UNICODE is defined.  The two are not interchangable at
runtime.  The only reason you can write just InternetOpen() in your code
instead of having to specify InternetOpenA() and InternetOpenW() is because
of the use of precompiler macros that hide that detail from your code.  But
you can't ignore it when you decide to import functions manually instead of
letting the linker do it for you.

It is a precompiler macro that defines string literals to either char* or
wchar_t* at compile time, depending on whether or not UNICODE is defined.
