Hallo versuchsmal mit der Function...
Delphi-Quellcode:
function GetConsoleOutput(const Command: String; var Output, Errors: TStringList): Boolean;
var
StartupInfo: TStartupInfo;
ProcessInfo: TProcessInformation;
SecurityAttr: TSecurityAttributes;
PipeOutputRead: THandle;
PipeOutputWrite: THandle;
PipeErrorsRead: THandle;
PipeErrorsWrite: THandle;
Succeed: Boolean;
Buffer: array [0..255] of Char;
NumberOfBytesRead: DWORD;
Stream: TMemoryStream;
begin
//Initialisierung ProcessInfo
FillChar(ProcessInfo, SizeOf(TProcessInformation), 0);
//Initialisierung SecurityAttr
FillChar(SecurityAttr, SizeOf(TSecurityAttributes), 0);
SecurityAttr.nLength := SizeOf(SecurityAttr);
SecurityAttr.bInheritHandle := true;
SecurityAttr.lpSecurityDescriptor := nil;
//Pipes erzeugen
CreatePipe(PipeOutputRead, PipeOutputWrite, @SecurityAttr, 0);
CreatePipe(PipeErrorsRead, PipeErrorsWrite, @SecurityAttr, 0);
//Initialisierung StartupInfo
FillChar(StartupInfo, SizeOf(TStartupInfo), 0);
StartupInfo.cb:=SizeOf(StartupInfo);
StartupInfo.hStdInput := 0;
StartupInfo.hStdOutput := PipeOutputWrite;
StartupInfo.hStdError := PipeErrorsWrite;
StartupInfo.wShowWindow := sw_Hide;
StartupInfo.dwFlags := STARTF_USESHOWWINDOW or STARTF_USESTDHANDLES;
if CreateProcess(nil, PChar(command), nil, nil, true,
CREATE_DEFAULT_ERROR_MODE or CREATE_NEW_CONSOLE or NORMAL_PRIORITY_CLASS, nil, nil,
StartupInfo, ProcessInfo) then begin
result:=true;
//Write-Pipes schließen
CloseHandle(PipeOutputWrite);
CloseHandle(PipeErrorsWrite);
//Ausgabe Read-Pipe auslesen
Stream := TMemoryStream.Create;
try
while true do begin
succeed := ReadFile(PipeOutputRead, Buffer, 255, NumberOfBytesRead, nil);
if not succeed then break;
Stream.Write(Buffer, NumberOfBytesRead);
end;
Stream.Position := 0;
Output.LoadFromStream(Stream);
finally
Stream.Free;
end;
CloseHandle(PipeOutputRead);
//Fehler Read-Pipe auslesen
Stream := TMemoryStream.Create;
try
while true do begin
succeed := ReadFile(PipeErrorsRead, Buffer, 255, NumberOfBytesRead, nil);
if not succeed then break;
Stream.Write(Buffer, NumberOfBytesRead);
end;
Stream.Position := 0;
Errors.LoadFromStream(Stream);
finally
Stream.Free;
end;
CloseHandle(PipeErrorsRead);
WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
CloseHandle(ProcessInfo.hProcess);
end
else begin
result:=false;
CloseHandle(PipeOutputRead);
CloseHandle(PipeOutputWrite);
CloseHandle(PipeErrorsRead);
CloseHandle(PipeErrorsWrite);
end;
end;
Aufruf der Funktion
Delphi-Quellcode:
procedure TForm1.BitBtn1Click(Sender: TObject);
var Output, Errors: TStringList;
begin
Output:=Tstringlist.Create;
Errors:=TStringList.Create;
GetConsoleOutput('attrib.exe C:\*.*',Output,Errors);
listbox1.Items.Text:=output.Text;
listbox2.Items.Text:=Errors.Text;
Errors.free;
Output.Free;
end;
