Hi,
I'm creating a mail and I'm trying to attach a file to the mail. My problem is when I click the attach button the browse window appears, the option is able to attach but the attachment is not recieved in the reciever(outlook) only the mail is recieved. I don't know what coding I forgot. Please say me what coding I forgot.

void CZapMailDlg::OnAttachfiles() 
{
	// TODO: Add your control notification handler code here
// TODO: Add your control notification handler code here
	CString file;
   // **** I had some proble with the flags OFN_ALLOWMULTISELECT of the CFileDialog ?????
   // **** If I took multiple selection bigger then I could view on the selection, the list
   // **** returned is bad ???
   CFileDialog dialog(TRUE,_szFilter,NULL, OFN_ALLOWMULTISELECT | OFN_HIDEREADONLY | OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_EXPLORER);
   dialog.DoModal();
   POSITION pos = dialog.GetStartPosition();
   while (pos != NULL)
   {
      file = dialog.GetNextPathName( pos );
      m_ListBox.AddString(file);
   }

In your code, you are only adding the file names to a list box. Since you don't show where you are sending the email, we can't really tell what is missing.

I found 2 links that might help on sending attachments using MFC:

http://support.microsoft.com/kb/200174[^]
http://www.example-code.com/mfc/smtp_sendEmailWithAttach.asp[^]

Also, when you are using OFN_ALLOWMULTISELECT, you must ensure that the buffer is large enough to contain all the file names:

C++

CFileDialog dialog(TRUE,_szFilter,NULL, OFN_ALLOWMULTISELECT | OFN_HIDEREADONLY | OFN_FILEMUSTEXIST);
//before displaying the dialog
//give a big buffer to store the file names
TCHAR buffer[5000];
dialog.m_ofn.lpstrFile = buffer;
dialog.m_ofn.nMaxFile = sizeof(buffer) / sizeof(TCHAR);
if (dialog.DoModal() == IDOK)
{
   //user clicked OK
   ...
}
