问题描述
我编写了一个程序,其中包含2个选项卡示例tab1和示例选项卡2.我使用mytabctrl.h和mytabctrl.cpp来构建选项卡。现在我想要做的是当点击第一个标签i-2样本标签1中的确定按钮时,它打开第二个标签i-e样本标签2。怎么做才需要帮助。
我尝试过:
主对话框的头文件是maindialog.h
i have written a program which contain 2 tabs sample tab1 and sample tab 2. i used mytabctrl.h and mytabctrl.cpp to build tabs. Now what i want to do is that when click the ok button in 1st tab i-2 sample tab1 it opens the 2nd tab i-e sample tab2. how to do this need help.
What I have tried:
header file of main dialog is maindialog.h
#include "MyTabCtrl.h"
// CTabExample1Dlg dialog
class CTabExample1Dlg : public CDialog
{
// Construction
public:
CTabExample1Dlg(CWnd* pParent = NULL); // standard constructor
// MyTabCtrl m_tbCtrl;
// Dialog Data
//{{AFX_DATA(CTabExample1Dlg)
enum { IDD = IDD_TABEXAMPLE1_DIALOG };
MyTabCtrl m_tbCtrl;
//}}AFX_DATA
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CTabExample1Dlg)
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
//}}AFX_VIRTUAL
// Implementation
protected:
HICON m_hIcon;
// Generated message map functions
//{{AFX_MSG(CTabExample1Dlg)
virtual BOOL OnInitDialog();
afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
afx_msg void OnPaint();
afx_msg HCURSOR OnQueryDragIcon();
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
