调用dos,如何获取打开的dos窗口的信息。例如,调用一个dos编译命令,如何将编译结果显示到一个memo里?
 
简单方法可以将DOS下编译结果重定向到一个文件,然后再读到memo里。
 
如何得到DOS命令的结果又不想输出到文件?

procedure RunDosInMemo(DosApp:String;AMemo:TMemo);
const
ReadBuffer = 2400;
var
Security : TSecurityAttributes;
ReadPipe,WritePipe : THandle;
start : TStartUpInfo;
ProcessInfo : TProcessInformation;
Buffer : Pchar;
BytesRead : DWord;
Apprunning : DWord;
begin
With Security do begin
nlength := SizeOf(TSecurityAttributes);
binherithandle := true;
lpsecuritydescriptor := nil;
end;
if Createpipe (ReadPipe, WritePipe,
@Security, 0) then begin
Buffer := AllocMem(ReadBuffer + 1);
FillChar(Start,Sizeof(Start),#0);
start.cb := SizeOf(start);
start.hStdOutput := WritePipe;
start.hStdInput := ReadPipe;
start.dwFlags := STARTF_USESTDHANDLES +
STARTF_USESHOWWINDOW;
start.wShowWindow := SW_HIDE;
if CreateProcess(nil,
PChar(DosApp),
@Security,
@Security,
true,
NORMAL_PRIORITY_CLASS,
nil,
nil,
start,
ProcessInfo)
then
begin
repeat
Apprunning := WaitForSingleObject
(ProcessInfo.hProcess,100);
Application.ProcessMessages;
until (Apprunning <> WAIT_TIMEOUT);
Repeat
BytesRead := 0;
ReadFile(ReadPipe,Buffer[0],
ReadBuffer,BytesRead,nil);
Buffer[BytesRead]:= #0;
OemToAnsi(Buffer,Buffer);
AMemo.Text := AMemo.text + String(Buffer);
until (BytesRead < ReadBuffer);
end;
FreeMem(Buffer);
CloseHandle(ProcessInfo.hProcess);
CloseHandle(ProcessInfo.hThread);
CloseHandle(ReadPipe);
CloseHandle(WritePipe);
end;
end;
 
多人接受答案了。
