Rich Edit 사용법 메모

Rich Edit

VS의 Resource view 에서 컨틀롤만 등록하는것으로 동작 하는 것이 아니기 때문에

사용방법을 메모 해둔다.

사용방법이 어렵다기 보다, 종종 한줄 누락 시켜고서 왜 동작 안되는지 혼란스러워 할때가 있다.

 

리치에디트를 사용하기 위해서 맨처음에 해줘야 할게 있다

리치에디터에서 사용하는 구조체

리치에디트다 저런식으로 VS의 Resource view 에서 직접 그려서 사용할수도 있다.

그런데 이렇게 해줘도 class wizad의  member valiables 에는 안보인다 그래서

이것이 쓰이는 **.h 파일과 ***.cpp 에 직접 넣어주었다.

   

   

헤더 파일(아래)에는 원래 그냥 생기는건대.. 그걸 할수 없어서 그냥 직접 써줌

   

 enum { IDD = IDD_RICHEDIT_DIALOG };
 CEdit m_EditView4;
 CEdit m_EditView3;
 CEdit m_EditView2;
 CEdit m_EditView;
 int  m_FontColor;
 int  m_FontFont;
 CRichEditCtrl m_RichEdit;

   

cpp 파일 여기도 직접 해줬다.

   

CDialog::DoDataExchange(pDX);
 //{{AFX_DATA_MAP(CRichEditDlg)
 DDX_Control(pDX, IDC_EDIT_VIEW4, m_EditView4);
 DDX_Control(pDX, IDC_EDIT_VIEW3, m_EditView3);
 DDX_Control(pDX, IDC_EDIT_VIEW2, m_EditView2);
 DDX_Control(pDX, IDC_EDIT_VIEW, m_EditView);
 DDX_Radio(pDX, IDC_RADIO_COLOR_RED, m_FontColor);
 DDX_Radio(pDX, IDC_RADIO_FONT1, m_FontFont);
 DDX_Control(pDX, IDC_RICHEDIT3, m_RichEdit);
 //}}AFX_DATA_MAP

   

리치에디트를 사용하기 위해서 맨처음에 해줘야 할게 있다.

   

BOOL CRichEditApp::InitInstance()
{
 AfxEnableControlContainer();
 AfxInitRichEdit();   //이선언이 필요하다

   

   

**.cpp 파일에서 아래같은 내용이 필요하다.

HINSTANCE m_hinstRichEdit2 = NULL;  //<-- 이거 전역스럽게 한거다.

 m_hinstRichEdit2 = LoadLibraryA("RICHED20.DLL");

   

   

위와 같이 해놓으면 이제 사용할수 있다.

m_RichEdit 이것을 제어하면서 리치에디트를 활요한다.

   

간단한 예이다.
