CFileDialog error

[EDN Admin]

I am working on old VC++ code that could not be imported to newer VS. It had file inclusions like "Gui/FileDlg.h" and "Gui/FolderDlg.h.

and was using the following piece of code to access those modules :

Gui::FileDlg fileDlg(
TRUE,
System:ath::String(),
System:ath(),
OFN_CREATEPROMPT | OFN_ENABLESIZING,
_T("Log Files (*.dlf;*.isf)|*.dlf;*.isf|All Files (*.*)|*.*||"),
NULL
);

// Initializes m_ofn structure and sets title
fileDlg.setTitle(_T("Select input file"));

// Call DoModal
if (IDOK == fileDlg.doModal())
{
inputFileName = fileDlg.getPathName().toString().c_str();
}

I see that there is nothing like a FileDlg class in VS and there is something called as CFileDialog in MFC.

I replaced the existing code with :

CFileDialog dlg(TRUE);
dlg.m_ofn.nMaxFile = 511;
dlg.m_ofn.lpstrFilter="XML Files (*.xml)*.xmlText Files (*.txt)*.txtAll Files (*.*)*.*";
dlg.m_ofn.lpstrTitle="Save XML File As";

CString filename;

if(dlg.DoModal() == IDOK)
{
inputFileName = dlg.GetPathName(); // return full path and filename
}

and included #include "stdafx.h"

The Stdafx.h was created when I created a sample MFC application in VS2008. I copied the header file over to this project.

This is now erroring out at "ASSERT(afxCurrentResourceHandle != NULL)"

I have added AFX_MANAGE_STATE(AfxGetStaticModuleState()); at the very beginning of the code according to suggestions for similar error online. I am still unable to proceed.


1 more piece of info : when I copy pasted the CFileDialog code in the sample MFC application, that errors at CallWindowProc(oldWndProc, hWnd, nMsg, wParam, lParam) , in AfxWindowActivationWndProc.h

Thank you
