I went through the ordinary methods of finding documented or undocumented messages (SendMessage/PostMessage) supported by Windows Media Player 10:

AHK forum. I found a few posts (references in my notes below) with hints that there is a lot more out there.
Windows Media Player SDK. I didn't find anything of value. I may have not looked in the right places?
Web search. I did a medium-level web search. I was surprised to find more information on this forum than out in the wild.
WinSpector Spy. I couldn't get WMP to give up a single usable message. I think a few others have noted this.

Finally, out of desperation, I did a brute force attack and discovered some of the basic WM_COMMAND parameters and their associated responses. The results are included in my notes below.

:?:

Does anyone have a list of messages that can supplement or replace what I've found already? :?:

Thanks in advance for your assistance.

The following are my (unformatted and incomplete) notes:
I put it in a "Code" block for the fixed font.

Dear jballi,

Thats a long & extensive listing !

. Great work.

Brute Force?

You have referred to my post on WMP Postmessage commands. I used Spy++ that came bundled with Visual Studio 6 through which it was very easy to capture the WM_COMMAND parameters.

I think Spy++ should also work as a standalone. Maybe you can try Spy++ it from someone who uses VC++. Its an excellent tool.

Regards,

Great find and neat little program. This little program definitely goes into my toolbox. The wmploc.dll file was loaded with information. It was a pain in the butt but I updated my notes in the 1st post to reflect a bunch of new message parameters that I found. Thanks for the info!

JSLover wrote:

"RC" is my abbreviation for return code (ErrorLevel). "FAIL" is the standard AHK ErrorLevel returned when using SendMessage and there was a problem. WMP received and responded correctly to the message so I'm not sure why there was a problem. PostMessage works in these instances (Errorlevel is always(?) 0) so use it for these messages.

I try to use SendMessage whenever possible because 1) you can check the return code and 2) the script never gets ahead of itself (usually) because it always waits for a response before continuing.

I just wrote a script that sent a sequence of messages to WMP, one at a time, and I just observed what happened. Some of the stuff was obvious. The other stuff was a little tricky.

Goyyah wrote:

As I noted in the original post I used WinSpector Spy but couldn't get WMP to give up a single usable message. I don't have Spy++ but I may have to track it down so that I can use it in the future. I've gotten mixed reviews on the program but I just may have to bite the bullet.

Just out of curiosity, did you try Spy++ on Windows Media Player 10?

Thanks to everyone for your feedback. I appreciate it!

I'm still looking for more formal/complete documentation. If anyone has it, please pass it along.

Dear jballi,

No! I tried it with WMP7 in WIN98SE and noted down the Parameters. I was NOT surprised when same parameters worked with WMP9 in WINXP, because the buttons were generic and I guessed it right that it should be the same for the advanced versions. Maybe I should install WMP10 & give Spy++ a try!

@jbally: As JSLover wrote, using brute force may not be such a good idea, because some programs don't like receiving an unexpected WM_COMMAND and can crash...
Spy++ is bundled with Visual Studio. I don't know if it is available with the free version. Perhaps it is even available on MSDN, I don't know.
Note that Winspector Spy was made out of frustation with Spy++, so it is supposed to be better...

Concerning messages 19230-19237, is it possible to interact with the enhancements themselves once they've been shown?

Is there a way to increase/decrease the playback speed by a set amount rather than the stock "slow", "normal", or "fast"?

Unfortunately, I don't know how to take advantage of this information with AHK: http://msdn2.microsoft.com/en-us/library/bb262909(VS.85).aspx

I gave up on WMP and am using Gom Player, which I just found after a ton of searching, instead.

Hi Everyone,

I need to know what the equivalent of the enter key is. or in other words, how to play the current selected song (not toggle play/pause)

Thanks for your help,

Ricky
