我已經找到了網絡這個功能,工作得非常好德爾福多線程CMD
function GetDosOutput(CommandLine: string; Work: string = 'C:\'): string;
var
SA: TSecurityAttributes;
SI: TStartupInfo;
PI: TProcessInformation;
StdOutPipeRead, StdOutPipeWrite: THandle;
WasOK: Boolean;
Buffer: array[0..255] of AnsiChar;
BytesRead: Cardinal;
WorkDir: string;
Handle: Boolean;
begin
Result := '';
with SA do begin
nLength := SizeOf(SA);
bInheritHandle := True;
lpSecurityDescriptor := nil;
end;
CreatePipe(StdOutPipeRead, StdOutPipeWrite, @SA, 0);
try
with SI do
begin
FillChar(SI, SizeOf(SI), 0);
cb := SizeOf(SI);
dwFlags := STARTF_USESHOWWINDOW or STARTF_USESTDHANDLES;
wShowWindow := SW_HIDE;
hStdInput := GetStdHandle(STD_INPUT_HANDLE); // don't redirect stdin
hStdOutput := StdOutPipeWrite;
hStdError := StdOutPipeWrite;
end;
WorkDir := Work;
Handle := CreateProcess(nil, PChar('cmd.exe /C ' + CommandLine),
nil, nil, True, 0, nil,
PChar(WorkDir), SI, PI);
CloseHandle(StdOutPipeWrite);
if Handle then
try
repeat
WasOK := ReadFile(StdOutPipeRead, Buffer, 255, BytesRead, nil);
if BytesRead > 0 then
begin
Buffer[BytesRead] := #0;
Result := Result + Buffer;
end;
until not WasOK or (BytesRead = 0);
WaitForSingleObject(PI.hProcess, INFINITE);
finally
CloseHandle(PI.hThread);
CloseHandle(PI.hProcess);
end;
finally
CloseHandle(StdOutPipeRead);
end;
end;
唯一的問題是,當我運行GetDosOutput它運行的第三方應用程序,這是非常沉重,我的應用程序時間太長,有時掛起 當我從線程調用這個函數它同樣需要很長時間來重播 任何建議,使此功能多線程?
怎麼能多線程幫助? –
我討厭這段代碼決定命名布爾成功值Handle。 –
我不在乎,如果它只需要exe文件正常工作不會掛起 – dudey
