Question

CFileDialog Class GetFileName() function returns NULL, when try to get file name using ftp server path.

Raghav Kuppili 1

While browsing the local file from our system the file name is coming but when we are trying to browse it from FTP server path for e.g.,
FTP://xxx.xxx.xxx.xxx/ unable to get the file name in VC++.

This is the code i am trying to get FTP file.

CFileDialog dlg(TRUE, NULL, NULL, OFN_ENABLESIZING | OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_LONGNAMES,
_T("All Files|.||"), this);

if (dlg.DoModal() == IDOK)
{
    m_bEditingFilename = true;
    m_strLocalFile = dlg.GetPathName();
    m_strFileName = dlg.GetFileName();      
    UpdateData(FALSE);
}

Could you please tell me what kind of project that you are developing? A C# win32 application or other kinds of applications?

Hello,
as far as I know CFileDialog does not download files from web servers.
Maybe this code does:

TCHAR lFilter[] = _T("All Files (*.*)\0*.*\0");  
TCHAR lFile[0x10000] = _T("");  

OPENFILENAME lOFN;  

memset(&lOFN, 0, sizeof(lOFN));  

lOFN.lStructSize = sizeof(lOFN);  
lOFN.hwndOwner = this->GetSafeHwnd();  
lOFN.lpstrFilter = lFilter;  
lOFN.lpstrFile = lFile;  
lOFN.nMaxFile = sizeof(lFile) / sizeof(lFile[0]);  
lOFN.Flags = OFN_EXPLORER | OFN_ENABLESIZING;  

if (::GetOpenFileName(&lOFN) == TRUE) {  
    AfxMessageBox(lFile);  
}

Regards, Guido

You should open a new question. Nevertheless.
The string looks like you want to use it in CFileDialog. This is the correct syntax for CFileDialog:

TCHAR lFilter[] = L"hex-files (*.hex)|*.hex|mnt-files (*.mnt)|*.mnt||";
