在nx二次开发中经常会用到dll的全路径，上一级路径和名称，这里我对其进行封装，方便以后调用。

关键代码：

//头文件
#include <Windows.h>
#include <atlbase.h>

//获取当前dll所在的文件夹(mode:0-全路径名，1-dll的上一级路径，2-dll名称)
static string GetDllPanthAndName(int mode = 0);


string LiangFuns::UserUFBaseFun::GetDllPanthAndName( int mode )
{
	char szBuff[1024] = { 0 };
	HMODULE hModuleInstance = _AtlBaseModule.GetModuleInstance();
	GetModuleFileNameA(hModuleInstance, szBuff, 1024);
	string strName = szBuff;
	if (mode == 0)
	{
		string strdllPanth = strName;
		return strdllPanth;
	}
	else if (mode == 1)
	{
		string strDLLUPPath = strName.substr(0, strName.find_last_of("\\"));
		return strDLLUPPath;
	}
	else if (mode == 2)
	{
		string strALLName = strName.substr(strName.find_last_of("\\") + 1, strName.find_last_of(".") - (strName.find_last_of("\\") + 1));
		return strALLName;
	}
	return 0;
}

结果如下所示：
