Question

I am trying to get a dialog box [import] to launch from another dialog box [baseline].
I am including the required “.h” files however I am simply not able to create an instance of the import class. The error I get is this:

Error   1   error C2146: syntax error : missing ';' before identifier 'iDlg'    h:\shaunak\projects\sar_ccd\sar_ccd\baseline.h  202 1   Sar_CCD

The line of code that causes this [baseline.h]:

#include "Markup.h" 
#include<stdio.h>
#include<math.h>
#include "baseline_func.h"
#include "resource.h"
#include "Functions.h"
#include <stdlib.h>
#include "Sar_CCDDoc.h"
#include "Sar_CCDView.h"
#include <vector>
#include "MemAlloc.h"
#include "ReadFiles.h"
#include<vector>
#include<map>
#include "afxwin.h"
#include "import.h"
#include "Geocode.h"




**<SNIP: Taking out the irrelevant lines>**

     afx_msg void OnDestroy();
     virtual void PostNcDestroy();
     afx_msg void OnBnClickedNxtBase();
     CButton nextBaseline;


    import iDlg;               //doesnt work!
    CGeocoding cx;             //works!!!
};

However, if I create and instance of another class [Geocoding] using the same sysntax like so, it works fine:

#include "Geocoding.h"
CGeocoding cx;

Please help me figure out why.

In Visual Studio there is a keyword import or #import rather used to import a COM DLL and is used for other things as well. I guess you are experiencing a name collision there.

In order to get around it place your class import in a namespace

import.h

namespace myimport
{
  class import : public CDialog { 
  ...
  };
};

import.cpp

namespace myimport
{
  ...
};

then when you use it

myimport::import iDlg;

that should solve the issue, although renaming it to something else than “import” would be the better way to go.
