 Posted: Mon Oct 08, 2007 8:32 am Post subject: Question about "sendmessage" (C++/API) |
 |
|
Hi, I know you can simulate mouseclicks etc. on a minimized Window with "SendMessage".
Is it possibly to send a Message (with SendMessage) for talking to NPC's without clicking on them?
Another question:
How does plugin's work for example winamp or something like that.
There plugin (or an external programm) can play/pause/next etc on winamp.
Are those plugin's also working with SendMessage?

For your 2nd question about Winamp, yes, they use SendMessage. Winamp is designed to handle its own messages through send message using WM_COMMAND.
The commands for Winamp are:
| Code: | #define WA_PREV 0x9C6C
#define WA_PLAY 0x9C6D
#define WA_PAUSE 0x9C6E
#define WA_STOP 0x9C6F
#define WA_NEXT 0x9C70 |
Then to send the message you would use:
| Code: | | SendMessage(hwndOfWinamp, WM_COMMAND, WA_PLAY, NULL); |
And so on for the others as well.
Oh and another note, other players like iTunes have their own COM interface to use to communicate between itself and your program which is more reliable then using SendMessage. Winamp however doesn't come with one built in. But there are plugins for it.

Another Question to Winamp:
Is there a way to find thos "codes" manually? (With "codes" I mean 0x9C6C for example)

Yes, you can use an API spy on Winamp and then press the play, pause, etc buttons which should return the use of those codes with SendMessage. I found them that way a few versions ago. Windows Media Player works the same way too.

Could you give an example of how to using the command "spy" ?
Or just give a link to msdn with this command or whatever..I only find crap when I'm searching for the command spy...

It's not a command, it's a type of program. Visual Studio comes with one called Spy++. It should be under the Tools folder of your installation with the name spyxx.exe.
Once Spy++, hit ctrl+w to open a new window list. Find the window you wish to capture, right click on it, and choose messages. Now, all messages sent to the window will be captured.

Subclass the WNDPROC of the program using SetWindowLongPtr which will give you access to the main message loop of the window.
