承接专栏《MFC工控项目实例之三theApp变量传递对话框参数》
在调试目录Debug下创建DATA、LIB、TEMP三个文件夹
1、SEAL_PRESSURE.h中添加代码

class CSeatApp : public CWinApp
{
...
public:
	CString	m_Path;
	CString	m_DataPath,m_TempPath,m_LibPath;
...
};

2、SEAL_PRESSURE.cpp中添加代码

CSEAL_PRESSUREApp::CSEAL_PRESSUREApp()
{
	// TODO: add construction code here,
	// Place all significant initialization in InitInstance
			TCHAR exeFullPath[MAX_PATH];
	GetModuleFileName(NULL,exeFullPath,MAX_PATH);
	m_Path = exeFullPath;
	for(int i = m_Path.GetLength() - 1; i > 0 ; i --)
	{
		if(m_Path.GetAt(i) == '\\')
			break;
	}
	SetCurrentDirectory(m_Path);
	m_Path = m_Path.Left(i);
	m_DataPath = m_Path + "\\DATA\\";
	m_TempPath = m_Path + "\\TEMP\\";
	m_LibPath = m_Path + "\\LIB\\";	
	CreateDirectory(m_LibPath,FALSE);
	CreateDirectory(m_DataPath,FALSE);
	CreateDirectory(m_TempPath,FALSE);
}
