I think you can, you made me curious too, so I went to check the AppMon+ source code. the secret is here I think:
this was made by -dt-
code:
function setNowPlaying(enabled, type, format, title, artist, album, contentID){
if(typeof(type) == "undefined")type = "Music";
if(typeof(format) == "undefined")format = "";
if(typeof(title) == "undefined")title = "";
if(typeof(artist) == "undefined")artist = "";
if(typeof(album) == "undefined")album = "";
if(typeof(contentID) == "undefined")contentID = "";
enabled = Math.abs(enabled);
var WM_COPYDATA = 0x4A;
//reference
var song = Interop.Allocate(512);
//change the Music thing to Games or Office or
song.WriteString(0, "\\0" + type + "\\0" + enabled + "\\0" + format +"\\0" + title +"\\0" + artist + "\\0" + album + "\\0" + contentID + "\\0");
Debug.Trace(song.ReadString(0));
//write our copyDataStruct Structure
var copyDataStruct = Interop.Allocate(12);
copyDataStruct.WriteDWORD(0, 0x547); //dwData
copyDataStruct.WriteDWORD(4, song.Size); //cbData
copyDataStruct.WriteDWORD(8, song.DataPtr); //lpData
//Send it to all open messengers
var hMSGRUI = 0;
do{
hMSGRUI = Interop.Call("User32", "FindWindowExW", 0, hMSGRUI, "MsnMsgrUIManager", 0);
if(hMSGRUI > 0){
Interop.Call("User32", "SendMessageW", hMSGRUI, WM_COPYDATA, 0, copyDataStruct);
}
}while(hMSGRUI != 0);
}
mainly after //Send it to all open messengers, though I haven't quite figure out everything... try it yourself
shouldn't the thread be moved to scripts?
