could you please tell me how to write the program? Beginners do not understand,

CodePudding user response:

For example,
FileDlg. M_ofn. LpstrInitialDir=_T (" D: \ \ ");

CodePudding user response:

reference zhao4zhong1 reply: 3/f

such as
FileDlg. M_ofn. LpstrInitialDir=_T (" D: \ \ ");

so why not?

 
TCHAR szFilter []=_T (" ABC file (*. BIN) | *. BIN; *. BIN | | "); 
CFileDialog fileDlg (TRUE, _T (" (*. BIN) | *. BIN "), NULL, OFN_HIDEREADONLY, szFilter, NULL);//construct open file dialog box 
FileDlg. M_ofn. LpstrInitialDir=_T (" D: \ \ ");

Encapsulates the common file dialog box for Windows.


The class CFileDialog: public CCommonDialog


Few
Common file dialog boxes dojo.provide an easy way to implement the file Open and file Save As dialog boxes, and other file - selection dialog boxes) in a manner consistent with Windows standards.

You can use CFileDialog as is with the constructor provided, or You can derive your own dialog class from CFileDialog and write a constructor to suit your needs. In either case, these dialog boxes will concerns like standard MFC dialog boxes because they are derived from the CCommonDialog class.
