VC: File Replication (CFile class, file dialog box, edit Control)

1. Open a file and copy the content to another file:

2. open the file to be copied:

CFileDialog dlg (TRUE, "*", "", OFN_ALLOWMULTISELECT, NULL );

 

If (IDOK = dlg. DoModal ())

{

CString str = dlg. GetPathName ();

SetDlgItemText (IDC_EDIT1, str );

}

3. Implementation:

Void CCopyFileDlg: OnCopyfile ()

{

// TODO: Add your control notification handler code here

CString filename1 = "";

CString filename2 = "";

 

GetDlgItemText (IDC_EDIT1, filename1 );

CFileDialog dlg (false, "", "", OFN_ALLOWMULTISELECT, NULL );

If (IDOK = dlg. DoModal ())

{

Filename2 = dlg. GetFileName ();

CFile file1;

CFile file2;

File1.Open (filename1, CFile: modeReadWrite );

File2.Open (filename2, CFile: modeCreate | CFile: modeReadWrite );

Char * c;

C = new char [file1.GetLength ()];

File1.Read (c, file1.GetLength ());

File2.Write (c, file1.GetLength ());

File1.Close ();

File2.Close ();

// Delete c;

AfxMessageBox ("file copied successfully ");

}
