如何用createprocess调用带参数的命令行程序？

[lxwyk]

比如我想使用createprocess调用“netstat -an”,该如何调用啊？我将第二个参数设为'cmd/c netstat -an'时总不行。

[zwjchina]

去掉 'cmd/c '

谢谢楼上的，我在winxp下可以测试成功，但是，在win2003下就死掉了，不知道怎么回事，调试执行时，发现在
WaitForSingleObject那个函数那儿就执行不下去了，一直在等待。

我其实是想控制一个命令行程序并接收它的输出，代码如下：
procedure RunDos(const DosApp: string; var OutStr:Tstrings);
//DosApp是要执行的DOS指令或控制台程序,输出结果显示在OutStr中.
const
{设置ReadBuffer的大小}
ReadBuffer = 2400;
var
Security: TSecurityAttributes;
ReadPipe, WritePipe: THandle;
start: TStartUpInfo;
ProcessInfo: TProcessInformation;
Buffer: PChar;
BytesRead: DWord;
Buf: string;
fName : pchar;
begin
with Security do
begin
nlength := SizeOf(TSecurityAttributes);
binherithandle := true;
lpsecuritydescriptor := nil;
end;
{创建一个命名管道用来捕获console程序的输出}
if Createpipe(ReadPipe, WritePipe, @Security, 0) then
begin
Buffer := AllocMem(ReadBuffer + 1);
FillChar(Start, Sizeof(Start), #0);
{设置console程序的启动属性}
with start do
begin
cb := SizeOf(start);
start.lpReserved := nil;
lpDesktop := nil;
lpTitle := nil;
dwX := 0;
dwY := 0;
dwXSize := 0;
dwYSize := 0;
dwXCountChars := 0;
dwYCountChars := 0;
dwFillAttribute := 0;
cbReserved2 := 0;
lpReserved2 := nil;
hStdOutput := WritePipe; //将输出定向到我们建立的WritePipe上
hStdInput := ReadPipe; //将输入定向到我们建立的ReadPipe上
hStdError := WritePipe;//将错误输出定向到我们建立的WritePipe上
dwFlags := STARTF_USESTDHANDLES or STARTF_USESHOWWINDOW;
wShowWindow := SW_HIDE;//设置窗口为hide
end;

try
StrPCopy(fName,Form1.Edit1.Text);
{创建一个子进程，运行console程序}
if CreateProcess(nil, PChar(DosApp), @Security, @Security, true,
NORMAL_PRIORITY_CLASS,
nil, nil, start, ProcessInfo) then
begin
{等待进程运行结束}
WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
{关闭输出...开始没有关掉它，结果如果没有输出的话，程序死掉了。}
CloseHandle(WritePipe);
Buf := '';
{读取console程序的输出}
repeat
BytesRead := 0;
ReadFile(ReadPipe, Buffer[0], ReadBuffer, BytesRead, nil);
Buffer[BytesRead] := #0;
OemToAnsi(Buffer, Buffer);
Buf := Buf + string(Buffer);
until (BytesRead < ReadBuffer);
//SendDebug(Buf);
{按照换行符进行分割，并在OutStr中显示出来}
ShowMessage(Buf);
{
while pos(#10, Buf) > 0 do
begin
OutStr.Add(Copy(Buf, 1, pos(#10, Buf) - 1));
Delete(Buf, 1, pos(#10, Buf));
end;
}
end;
finally
FreeMem(Buffer);
CloseHandle(ProcessInfo.hProcess);
CloseHandle(ProcessInfo.hThread);
CloseHandle(ReadPipe);
end;
end;
end;
我是想测试netstat -an， 但是不行，输不出来，各位帮一下忙，急，多谢了
