Handle einer Form aus Taskbareintrag erhalten

[toms]

Vielleicht koennte jemand noch helfen, diese 3 Codefragemente nach Delphi zu uebersetzen

1.

Code:

SendMessage(hwndTW,TB_HITTEST,0,(LPARAM)(LPPOINT)lpPoint);

2.

Code:

TBBUTTON tbButton; 
TBBUTTON* pTBButton = &tbButton; 
DWORD_PTR lpTBButton = (DWORD_PTR)pTBButton;

3.

Code:

// Retrieve window handle of pressed btn 
BYTE localBuffer[BUFFER_SIZE]; 
BYTE* pLocalBuffer = localBuffer; 
DWORD_PTR ipLocalBuffer = (DWORD_PTR)pLocalBuffer; 
pLocalBuffer = localBuffer; 
ipLocalBuffer = (DWORD_PTR)pLocalBuffer
