Mixing Strings and CStrings

In the property pages for the app it says under General:

Use of MFC:  Use Standard Windows Libraries
Use of ATL: No

Does that help?

looking at the code I noticed there was no inclusion of stdafx.h, so I inserted the following line at the top of the file containing the CString definitions
 
#include "stdafx.h"

this produced a different error message:

fatal error C!!89: #error : WINDOWS.H already included.  MFC apps must not #include <windows.h>

this error referenced the following lines in afxv_w32.h

#ifdef _WINDOWS_
      #error WINDOWS.H already included.  MFC apps must not #include <windows.h>
#endif

I commented the '#include "stdafx.h"' out and read up on CString.  I foudn that it needed the following headers, which I put in:

#include <cstringt.h>
#include <atlstr.h>
#include <afxcoll.h>

This produced the same error message as the previous include:

fatal error C!!89: #error : WINDOWS.H already included.  MFC apps must not #include <windows.h>

Any Ideas????   What other information can I provide to help solve this?

Thanks

Dan, thanks for the response.  Yes I would feel better knowing it is correct from the start.

The code I originally pulled off of code project came with a .sln and .vcproj and that is what I started with; first doing the mods I needed before adding in the additional code (the stuff with the cstrings).

Actually, I guess what I really want to do is convert it to a dialog based app, however, it does a lot of console writes, which I guess I could convert to addstrings to a list box.   But my real concern with this approach would be some problem with the console code which would be the converse of the cstring problem.  Typically, can you easily convert a console app to a dialog app, assuming you handle all io to the console?

I took the initial approach of creating a console app from scratch with support for MFC, it seemed the simplest approach and I could later convert it to a dialog app.  

After creating the MFC console app, I brought over the socket server code and incorporated it.  Unfortunately there were a host of additional compilation problems.  It appears this code was written pretty tightly for win32.

So, I have another potential approach I might try which is:   The set of classes I am trying to incorporate into this console app comes as source and also as an OCX.

Question, can I incorporate the OCX into this win32 console app?  If so, please be specific.

thanks
Phil

If I go into

tools/add remove toolbox items... and then to the comm components tab I can scroll down to my OCX.  I can check the box and then say add.  But what next?

My level of knowledge here is that the next step would be to drag the ocx icon off of the toolbox and onto a dialog.   Then I would be able to include the .h and use the functions.

In a win32 console app, what do I do?

Thanks
Phil

This has been tough, but I think I'm down to the last couple of compilation errors.  The following is the code:

.h
   private :

      static void *operator new(size_t objSize, size_t bufferSize);
      static void operator delete(void *pObj, size_t bufferSize);

.cpp
void *CIOBuffer::operator new(size_t objectSize, size_t bufferSize)
{
   void *pMem = new char[objectSize + bufferSize];

   return pMem;
}

void CIOBuffer::operator delete(void *pObject, size_t /* bufferSize*/)
{
   delete [] pObject;
}



Errors:
error C2059: syntax error: 'string'
error C2091: function returns function
error C2802: static member 'operator new' has no formal parameters


Any idea on how to fix this?

PS. I should have made this 5000 point :)

Dan,

I give up on using this code i pulled from codeproject.  Don't know what I'm doing wrong and at this point I don't care.

Please could you recommend to me a base set of code which I can use as a socket server.

This code from codeproject was almost ideal as it created a 'socket thread pool' and a 'business thread pool'.   This is a link to it:
http://www.codeproject.com/internet/jbsocketserver3.asp?msg=1759049#xx1759049xx

I have a web site with some php which I have successfully talking to this server.  I am able to throttle the business pool side down to one and it will take multiple requests from the web and queue them up feeding them serially to the business logic side.  This is a requirement as my business logic can only handle one user at a time.

Are you aware of any similar code i can use?

Thanks for the points.  
I did check out that codeguru page and it looked like the author had written a nice piece of code.  As he said, it was designed to be a separate logic-only blackbox with the expectation that any desired kind of U/I code could be grafted onto it.  When you decided to give up on it, well, so did I :-)  Good luck in finishing your task.

Well,

After getting over my frustration, I had another go at it.  (My 19th attempt I think)

This time I put all the MFC code in a DLL.   This separated the two conflicting systems.

So, that part of the code is working very nicly...  

Onto my next set of problems :)

Thanks Dan,
Phil
