Statusbar auslesen

[toms]

Hallo, ich hab's mal so gemacht:

Delphi-Quellcode:

uses
  CommCtrl, uProcessMemMgr;

function GetStatusBarText(hStatusBarHandle: HWND; PanelNumber: Integer): string;
var
  PMM: TProcessMemMgr;
  NumberOfPanels, Len: Integer;
  PrcBuf: PChar;
  PartText: string;
begin
  if hStatusBarHandle = 0 then Exit;
  PMM := CreateProcessMemMgrForWnd(hStatusBarHandle);
  try
    NumberOfPanels := SendMessage(hStatusBarHandle, SB_GETPARTS, 0, 0);
    if PanelNumber < NumberOfPanels then
    begin
      Len := LOWORD(SendMessage(hStatusBarHandle, SB_GETTEXTLENGTH, PanelNumber, 0));
      if Len > 0 then
      begin
        PrcBuf := PMM.AllocMem(Len + 1);
        SendMessage(hStatusBarHandle, SB_GETTEXT, PanelNumber, Longint(PrcBuf));
        Result := PMM.ReadStr(PrcBuf);
        PMM.FreeMem(PrcBuf);
      end
      else
      begin
        Result := '';
      end;
    end;
  finally
    PMM.Free;
  end;
end;
