运行批处理
PROCESS_INFORMATION info;
CreateProcess( "c:\\aaa.bat ",NULL,NULL,NULL,FALSE,CREATE_DEFAULT_ERROR_MODE |NORMAL_PRIORITY_CLASS,NULL,NULL,NULL,&pinfo);


批处理执行期间，不断的FindWindow，就是这个aaa.bat的窗口，如果存在则跳过，500毫秒后再检查，直到没找到，说明已完成并关闭了，发现aaa.bat已运行完毕后，就可以使用以下代码获得exit code了:
int code;
GetExitCodeProcess(info.hProcess, &code);

==============================================
另有一个方法：

你的bat运行时，根据不同的运行的结果，在退出之前，建立一个同名文件，但内容不同，如运行的某处，要exit 1时，你这样：
@echo 1> ExitCode.txt
要exit 2时，
@echo 2> ExitCode.txt
程序运行之初要
del ExitCode.txt
这样，你只要不断的检测目录下是否有ExitCode.txt文件，如果有，说明已运行完毕，内容就是所要的ExitCode了。
