C++调用bat并实现传值

1.设置环境变量，这一类为路径

C++

  void bat(const string& sDirC, const string& sDirD) 
  {
        char Ddir[256];
	Ddir[0] = 0;
	sprintf_s(Ddir, "DDIR=%s%s", (char*)sDirD.data(), "\");
	_putenv(Ddir);        //将地址设置到当前环境中
	char Cdir[256];
	Cdir[0] = 0;
	sprintf_s(Cdir, "CDIR=%s%s", (char*)sDirC.data(), "\");
	_putenv(Cdir);                
          system("..\..\Bin\x64\copy.bat" ); 　　　　//调用bat 推荐下面那种
         /*if (WinExec("..\..\Bin\x64\copy.bat", SW_HIDE) < 32)
	{
		AfxMessageBox(L" 无法调用 ..\..\Bin\x64\copy.bat", NULL, MB_OK);
		return false;
	}*/
}    

 Bat

set tmpDir=%DDIR%
md %tmpDir%
if not exist %tmpDir% (
set tmpDir=%CDIR% 
md %tmpDir%
)

 2.直接传值

　　bat默认只能获取到1-9个参数，分别用%1 %2 ... %9引用，如果传给bat的参数大于9个，就要用shift。

void bat(const CString& csVersion)
{
        char packCmd[256];
	sprintf_s(packCmd, "%s%s","..\..\Bin\x64\pack.bat ", T2A(csVersion));

	//system(packCmd);

	if (WinExec(packCmd, SW_HIDE) < 32)
	{
		AfxMessageBox(L"..\..\Bin\x64\pack.bat ", NULL, MB_OK);
		return false;
	}
}    

set abc=XXX%1
