Me personally? None. I merely pointed it out to the OP before it became a
question. I don't like As Any. It's like a Variant, which I don't prefer
either.

I have two versions of SendMessage, ByString and ByLong, properly declared.
Takes a lot of the guesswork out of it.

ha. I wondered about that. As I assumed you knew all about "As Any".

I combined the first line with the last and it looked like you were
asking, so I just responded - just in case.

Contrary to popular opinion, I do actually know one or two things about VB -
versus the general idea I'm only around to poke (no pun) the neighborhood
trolls back across to their side of the tracks. <eg>

Note also that using a type library means it won't do any conversion at all.

There are many advantages to using a Type Library instead of Declare
directives for Standard DLLs, essentially removing some over-head in
making the call, but unfortunately this is not one of them.

The conversion VB does from a VB BSTR to an ANSI BSTR is built into
the VB VM (Runtime), and always occurs when VB passes a BSTR to an
external library (Win32 or anything else).

This *feature* was provided so that VB programs would be compatible
with both Windows 9x (non-Unicode) and Windows NT (Unicode) operating
systems. It even occurs if running on WinNT and making a call into
Unicode entry points in the Win32 (Wide versions).
