Я делаю так:
HWND h; h = FindWindow("Winamp v1.x",0); Form1->Caption = SendMessage(h, WM_WA_IPC, 0, 211);
Но возвращается ведь указатель. Каким образом получить строку?

Из внешней программы(не плагина) названия песни можно получить из заголовка WinAmp"овского окна.
uses Windows;
var
hwndWinamp: HWND;
title: array[0..200] of char;
begin
hwndWinamp: =FindWindow("Winamp v1.x", nil);
GetWindowText(hwndWinamp, @title, SizeOf(title));
title[strlen(title)-8]: =#0;
Label1.Caption:=title;
end;

+ на torry.net куча готовых решений.

А так вот ешшо лучше:))) гы:)
var hWinamp: HWND; hProcess: THandle; dwProcessId, nBytesRead: DWORD; curItem: Integer; lpStr: PChar; buffer: array[0..MAX_PATH - 1] of char; const IPC_GETPLAYLISTFILE = 211; IPC_GETPLAYLISTTITLE = 212; IPC_GETLISTPOS = 125; WM_WA_IPC = WM_USER; begin hWinamp := FindWindow("Winamp v1.x", nil); GetWindowThreadProcessId(hWinamp, @dwProcessId); hProcess := OpenProcess( PROCESS_VM_OPERATION or PROCESS_VM_READ or PROCESS_VM_WRITE, FALSE, dwProcessId); if hProcess = 0 then begin Exit; end; curItem := SendMessage(hWinamp, WM_WA_IPC, 0, IPC_GETLISTPOS); lpStr := PChar(SendMessage(hWinamp, WM_WA_IPC, curItem, IPC_GETPLAYLISTFILE)); ReadProcessMemory(hProcess, lpStr, @buffer, MAX_PATH, nBytesRead); (* Теперь можешь делать с buffer всё что угодно - там имя текущего файла:) Enjoy :) *) CloseHandle(hProcess); end;
