MFC如何从MFCEditBrowseControl获取路径并将其复制到编辑控件？

Question

I am intended to get path from CMFCEditBrowseControl and copy it to the CEdit edit box. I have done the following which is getting caption of a dialog not path, please let me know how to get the path using MFC and c++ to save particular file to the destination?

CString strTextone;
(CMFCEditBrowseCtrl *) GetDlgItem(IDC_MFCEDITBROWSE1)-&inFileCtrl;
GetWindowText(strTextone);
(CEdit *) GetDlgItem(IDC_EDIT2)-&e_Edit;
SetWindowText(strTextone);

This is my code. I am beginner to this, so please correct my mistakes!

You can get a pointer to CWnd :

CString strTextone;
CWnd* ptr = GetDlgItem(IDC_MFCEDITBROWSE1);
ptr->GetWindowText(strTextone);
ptr->SetWindowText(_T("something else"));

This will work because SetWindowText/GetWindowText are CWnd methods. You could use CMFCEditBrowseCtrl* cast but that's not always safe. The preferred method is to declare a class member:

CMFCEditBrowseCtrl mfc_editbrowse;

And add subclass in DoDataExchange .

void CMyDialog::DoDataExchange(CDataExchange* pDX)
{
    CDialog::DoDataExchange(pDX);
    DDX_Control(pDX, IDC_MFCEDITBROWSE1, mfc_editbrowse);
}

Then you can use m_editbrowse to access CMFCEditBrowseCtrl methods.
