내 남자의 길~!

error C2664: 'XXXXXXXXW' : cannot convert parameter 1 from 'const char [13]' to 'LPCWSTR'

error C2664: 'XXXXXXXXW' : cannot convert parameter 2 from 'const char [13]' to 'LPCWSTR'

이것도 뭐 글을 길게 쓰고 싶지 않은 에러상황이다. 유니코드 관련 error 인데..

다른방법도 여러개 찾았지만 가장 적합한 방법은 Project properties를 설정하는 것!!

간단하게 방법만 남기고 넘어가자.. 피곤하다 캐삽질 짜잉나!!!!

프로젝트 선택하고 오른쪽 클릭 properties 클릭!)



스샷으로 대충 때우려 했지만 스샷으로 어디지 헷갈릴수도 있으니

Configuration Properties -> Generall -> Project Defaults -> Character Set   에 보면

Use Unicode Character Set  또는 Use Multi-Byte Character Set 라면 과감히 Not Set 선택하자!!

error Clear!!!  아 글 쓰는것도 힘들구나.. 좀더 신중히 글을 작성해야하지만 핵심만 간단히^^;

public class test  
{
public static void main(String[] args)  
{
java.util.Enumeration e = System.getProperties().propertyNames();

while(e.hasMoreElements()){
String obj = (String)e.nextElement();

System.out.print(obj + " ===> ");
System.out.println(System.getProperty(obj));
}
}
}

가끔 OS 및 JVM에 의존적인 환경변수들을 가져올 필요가 있습니다.
그럴때, API 레퍼런스를 찾아보면 나오지만, 그래도 정리를 해 봅니다..
