This for sure has been an earlier question here on CP, but I can’t find any related topic…
I have an xml-file that I want to read through and put its contents in a CString. I have signs like å, ä and ö in the file.

Have you looked into:

CFile file(...);
int nLength = file.GetLength();
CString str;
LPSTR lpBuffer = str.GetBuffer(nLength);
file.Read(lpBuffer, nLength);
str.ReleaseBuffer(nLength);

Now the contents of the file are in str.

error C2664: 'Read' : cannot convert parameter 1 from 'const char *' to 'void *'

on line:
file.Read(lpBuffer, nLength);

My bad. Use LPSTR instead.

Still got that problem with å, ä, ö...

Not compiling with UNICODE.

What exactly is the problem? The CString class is Unicode-aware so it should have no trouble reading whatever is in the file.

You could also e-mail me a small sample of the XML file and I'll give it a go on my end.

Se link:
http://www.ceco.se/Files/Project1.xml[^]

for the XML file. On third row there is an "ö"

When I print the CString (for e.g. using AfxMessageBox(...)) the ö becomes like "~æ".

Don't use MessageBox() (or AfxMessageBox()) to verify the contents of a variable. Smile | :)

After the contents of the file have been read into the CString object, look at positions 0x5c and 0x5d in the debug window (e.g., str.m_pchData[0x5c],x). You'll notice that they are indeed 0xb6 and 0xc3, respectively.

But if I want to print the CSting to a label for e.g. it still becomes not an ö...

It may require a different font. By default, dialog boxes use MS Sans Serif which may not support that particular character.

Hi,

I have a small question:

Working with Visual C++ .Net 2003, if I choose to create a .NET project, does this mean that I must work with managed C++ ?

Is MFC and Managed code mutually exclusive, or what is the relation between the two?

thanks

regards

The document at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_core_generic.2d.text_mappings_in_tchar..h.asp[^] says _TCHAR, when _MBCS is defined, is just a char.

The document at http://www.codeproject.com/cpp/unicode.asp[^]says _TCHAR, when _MBCS is defined, can be 1 or 2 bytes.

Can soemone clarify this as I don’t understand the purpose of _TCHAR if defining _MBCS is same as not defining it Smile | :)

Thanks.

TCHAR is 1 byte when UNICODE is not defined. The "characters" of the language may be 1 or 2 bytes long.

Using stdafx.h in multiple directories

raghavr21-Mar-05 0:54

raghavr2

1-Mar-05 0:54

Hi,

I have an MFC Dll with multiple directories like,

MyProj,
MyProj/Sample1
MyProj/Sample2

The class files are under the Sample1 and Sample2 directories. However, the StdAfx.cpp and the StdAfx.h (precompiled header) are under the parent directory (MyProj).

My question is, If we need to "Use precompiled header" for the cpp files under Sample1/2 directories, is it sufficient if we
#include "StdAfx.h" and "Use precompiled header" through "StdAfx.h" for these files

Or

Do we need to give the relative paths for the precompiled header
like #include "../StdAfx.h" and the same for the Use precompiled header "../StdAfx.h"

Thanks in advance,
Raghav

Blake Miller1-Mar-05 6:19

Yes, you can get by with a single stdafx.h and stdafx.cpp for each project.

My understanding is that your project (DSP, DSW) is in a single location and your source files are in different folders. This works fine. The single stdafx.h and stdafx.cpp should be in the location where the DSP and DSW are located.

You might need to include the other folders int he 'proeprocessor' tab - as additional include directories, so the header files in those other folders are visible to files in the project folder and to each other.

I do this all the time with a folder of 'common code' and other folders containing their own projects, each referencing headers and source files in the 'common code' folder.

Hi,

Thanks for the reply. Actually, it works by giving the common "StdAfx.h" as the precompiled header for all the source files under different sub directories of the project.

However, when i try to open the StdAfx.h file (using "Open document") from the #include "StdAfx.h" in the cpp file (which is in the sub directories), it is opening a StdAfx.h file of another DLL project. I am not sure if the compiler is taking the proper StdAfx.h file during compilation.

Actually, we have around 20 DLL projects under the same "Sources" directory and each one of these DLLs has a separate StdAfx.h file. How can we be sure that the StdAfx.h file included in a DLL is not referenced by the source files of another DLL project?

Thanks,
Raghav

I am not sure, except to check your global includes setting and then to check the preprocessor setting for the debug and release of each project.

Also, it is possible that one of the paths might have snuck into an environment variable, but I thought those are only used for command line builds.

I usually do this, and have avoided many problems as a result:
1. I put ONLY the Platform SDK include paths into the global include paths (Tools Menu, Options Menu, Dirctores Tab, Include Files)
2. I never put anything implying a relative path for the stdafx.h. It is always plainly
#include "stdafx.h"
3. I modify the preprocessor setting for each project to include the local directory first as in "." and then follow it with the other folders required.
4. I never place a stdafx.h or stdafx.cpp in a folder that is going to contain 'shared' header or source files, as this will lead to the confusion about which stdafx.* to actually include.

I think someone wrote a 'header dependency walker' type tool and posted it on CodeProject. Maybe it will help you to determine which files are including which stdafx.h
