将另一个进程console输出的内容输出到某内存中去

其实这个也就是说，输出的重定向，下面的方法主要是重定向到管道中来实现的：

const string CADBHelper::DoCommand( const string cmd )

{
STARTUPINFOA si;
SECURITY_ATTRIBUTES sa;
PROCESS_INFORMATION pi;
string str="";
char ReadBuf[1024] = {0};
DWORD ReadNum;
HANDLE hRead; // 管道读句柄
HANDLE hWrite; // 管道写句柄


sa.nLength = sizeof(SECURITY_ATTRIBUTES);
sa.bInheritHandle = true;
sa.lpSecurityDescriptor = NULL;
BOOL bRet = CreatePipe(&hRead, &hWrite, &sa, 0); // 创建匿名管道
if(!bRet) return "";
GetStartupInfoA(&si);
si.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;
si.hStdOutput = hWrite;
si.hStdError = hWrite;
si.hStdInput = hRead;
bRet = CreateProcessA(NULL, (char *)cmd.c_str(), NULL, NULL, 
true, NORMAL_PRIORITY_CLASS, NULL, NULL, &si, &pi);
if (!bRet)
{
CloseHandle(hRead);
CloseHandle(hWrite);
return "";
}
CloseHandle(hWrite);
WaitForSingleObject(pi.hProcess, 3000); //等待执行返回
if (cmd.find("install") != std::string::npos)
{
while (ReadFile(hRead, ReadBuf, sizeof(ReadBuf)-1, &ReadNum, NULL))
{
ReadBuf[ReadNum] = '\0';
str = str + ReadBuf;
}
}
else
{
if (ReadFile(hRead, ReadBuf, sizeof(ReadBuf)-1, &ReadNum, NULL))
{
ReadBuf[ReadNum] = '\0';
str = str + ReadBuf;
}
}
if (!str.empty() && str != (""))
{
str = utf2ansi(str.c_str(), str.size());
}
CloseHandle(hRead);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
std::tstringstream ss;
std::wstring wStr;
StringHelper::MultiByteToUnicode(str, wStr);
ss << _T("AndroidMgr DoCommand Result:");
ss << wStr;
ss << _T("\n");
return str;
}
