An die Daten von PNotifyIconData herankommen

[helen]

Das Icon wird so in einen Record verpackt:

Code:

function SendData (dwMessage: Dword; lpData : PNotifyIconData) : Boolean;
  type
    TBNApaket = record
       cbsize : Cardinal;
       Icon : HIcon;
       szTip : String [100];
       CallBackMsg : Cardinal;
       Flags : Cardinal;
       ID : Cardinal;
       Wnd : HWND;

       dwMessage : DWord;
    end;

  var paket : TBNApaket; lppaket : ^TBNApaket; aCopyData: TCopyDataStruct;
      tmp : TIcon;
begin
//  tmp := TIcon.Create;
//  tmp.Handle := lpData^.hIcon;

  lppaket := @paket;
  lppaket^.cbsize := lpdata.cbSize;
  lppaket^.Icon   := lpdata.hIcon;                  // !!Icon verpacken
  lppaket^.szTip  := lpdata.szTip;
  lppaket^.CallBackMsg := lpdata.uCallbackMessage;
  lppaket^.Flags  := lpdata.uFlags;
  lppaket^.ID     := lpdata.uID;
  lppaket^.Wnd    := lpdata.Wnd;

  lppaket^.dwMessage := dwMessage;

//  tmp.free;

  with aCopyData do begin
    dwData := 0;
    cbData := Sizeof (paket) + 1;
    lpData := lppaket;
  end;

  SendMessage (FindWindow('TX11TBNA', nil), WM_COPYDATA, 0, Longint(@aCopyData));
end;

Und soll am anderen Ende so wieder ausgepackt werden:

Code:

function TX11TBNA.ImgList_AddIcon (bIcon : HIcon) : Integer;
  var tmp : TIcon;
begin
  tmp := TIcon.Create;
  try
   // If bIcon^ = 0 then ShowMessage ('Icon null');

    tmp.Handle := bIcon;  // <===
    result := ImageList1.AddIcon(tmp);
    if result=-1 then    // auf jeden Fall prüfen, damit man weiss was Sache ist
//       ShowMessage('AddIcon failed !');  // anzeigen oder sonstwie protokollieren
  finally
    tmp.Free;
  end;
end;


procedure TX11TBNA.WMCopyData (var Msg : TWMCopyData);
  type
    TBNApaket = record
       cbsize : Cardinal;
       Icon : HIcon;
       szTip : String [100];
       CallBackMsg : Cardinal;
       Flags : Cardinal;
       ID : Cardinal;
       Wnd : HWND;

       dwMessage : DWord;
    end;

  var paket : TBNApaket; lppaket : ^TBNApaket;
      i, imgpos : Integer;
begin
  lppaket := Msg.CopyDataStruct.lpData;
  paket := lppaket^;


  imgpos := -1;
  For i := 0 to Listview1.Items.Count-1 do
      if (StrToInt (Listview1.Items[i].SubItems[0]) = paket.Wnd){ and
         (StrToInt (Listview1.Items[i].SubItems[1]) = paket.uID)} then
         imgpos := I;

  if paket.dwMessage = NIM_ADD then begin
     //ShowMessage ('ADD');

     If imgpos < 0 then
        with Listview1.Items.Add do begin
              ImageIndex := ImgList_AddIcon (paket.Icon); //ImageList1.AddIcon (paket.Icon);
              Caption := paket.szTip;

              SubItems.Add (IntToStr(paket.Wnd));
              SubItems.Add (IntToStr(paket.ID));
        end;
  end
  else

  if paket.dwMessage = NIM_MODIFY then begin
     //ShowMessage ('Modify');

     If imgpos > -1 then
        with ListView1.Items [imgpos] do begin
             ImageIndex := ImgList_AddIcon (paket.Icon); // ImageList1.AddIcon (paket.Icon);
              Caption := paket.szTip;
        end
     else
         with Listview1.Items.Add do begin
              ImageIndex := ImgList_AddIcon (paket.Icon); // ImageList1.AddIcon (paket.Icon);
              Caption := paket.szTip;
              
              SubItems.Add (IntToStr(paket.Wnd));
              SubItems.Add (IntToStr(paket.ID));
        end;
  end
  else

  if paket.dwMessage = NIM_DELETE then begin
     //ShowMessage ('Delete');

     If imgpos > -1 then
        ListView1.Items.Delete (imgpos);
  end

  else ShowMessage ('Command not found!');
end;

Aber das blöde Bild ist leer... Jedenfalls ist ImageList1.AddIcon(tmp) = -1 ...

Was kann da noch falsch sein?
