Visual C++ get string from Cedit

问题

This is probably a pretty basic question, but I can't seem to get it. I am working on a visualC++ project and I basically want to get a string from a GUI and then use that as a filename. I have written the following thus far, where IDC_FILE_NAME is the ID of the edit control box but I'm not sure if that is even the way to accomplish this.

m_pFileName = (CEdit*)GetDlgItem( IDC_FILE_NAME );

CString fName =_T(" ");
GetDlgItemTextA(IDC_FILE_NAME, fName);

The answer is YES and NO. YES if properly used, NO, not as you do it. Do not use UNICLODE/ANSI specific versions of functions unless you want to force UNICODE or ANSI. Your code should look like:

    CString csText;
    GetDlgItemText(IDC_FILE_NAME, csText);

NOTE GetDlgItemText

This has been tested with VS2015:

//
// Get string from CEdit m_ceDate;
// where
// DDX_Control(pDX, IDC_EDIT_DATE, m_ceDate);

char cdateBuf[128];
UINT nCountOfCharacters = GetDlgItemText(IDC_EDIT_DATE, cdateBuf, 16);
CString csDate = cdateBuf;
