OnSize(){....sss.MoveWindow(10, 10,cx-20,cy-60);....}BTW, the problem is that the first position of slider difference between after resize of dialog.So I want to know that how to set first position of slider in InitialDialog.update 2I've got followed up with your source. but it's difference working between you and me.When I run first I got thisWhen I resize the dialog a very little I got thisAs you can see, the slider is disappeared.I have update here the MyDlg.cpp// mfc_test5Dlg.cpp : implementation file//#include "stdafx.h"#include "mfc_test5.h"#include "mfc_test5Dlg.h"#include "afxdialogex.h"#include "Testview.h"#include <Magick++.h>extern CTestview *global_TestView;char * fileposition;#ifdef _DEBUG#define new DEBUG_NEW#endif// CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialogEx{public: CAboutDlg();
