[팁]외부 프로그램의 상태표시줄의 Text 가져오기
//안녕하세여~ 구창민입니다.
//요런 특별한 작업을 해야하는 경우가 생길수도 있겟지여..ㅋㅋ
//아래는 인터넷부라쟈의 상태표시줄의 내용을 가져오는 예제입니다.
//그럼~ 즐거운 프로그래밍 하시길~~

To Read the statusbar in another process, use this function:
Damit kann man auch in einem anderen Prozess den Statusbar Text bei Subpanels auslesen
}
uses
CommCtrl, uProcessMemMgr { from Download };
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;
