Kanji character display in 7.1 MFC application vs. 6.0 MFC

Here is the problem we've encountered. An application that used to
successfully display Japanese Kanji characters no longer does so when
recompiled with 7.1

When compiled with the 6.0 compiler, both of the following methods are
successful in displaying Japanese characters in a multi-line CEdit control on
a machine that is fully configured as a Japanese machine (Japanese version of
Windows 2000 SP4). The same code, compiled with 7.1, only displays blanks or
incorrect characters. The program is compiled for MBCS, not Unicode, so we
are in effect calling SetWindowTextA in Method 1.

METHOD 1:
=========

// Make a little buffer for the MBCS character

TCHAR cPtr[6];
for (int i = 0; i < 6; i++) cPtr = 0;
int iRet = WideCharToMultiByte (932, 0, L"\x3042", 1, cPtr, 6, NULL, NULL);
// Display Hiragana A character
m_cProblemEdit.SetWindowText(cPtr);

METHOD 2:
=========

CString sProblem;
//...Iinitialize sProblem with Kanji string ....
// Display string
m_CProblemEditSetWindow(sProblem);
 
Hi,

For a VC7.1 project, you need to specify its "Culture" to Japanese, this
will make your programdisplay the Japanese Kanji characters as expected.

You can configure it in the Project property configuration(Project Property
Pages/Resources/General/Culture).


Thanks!

I'm a little baffled by this, but maybe I don't understand it. What if the
application is supposed to work with many "cultures" and not just the
Japanese culture? As long as one doesn't switch their default (for
non-unicode apps) code page, our app will support any double-byte language.
Sounds like if we compiled with VC7.1 it no longer would. Am I missing
something?

Hi Michael,

For a general .NET WinForm application, you can set the target Form's
"Localizable" property to true, then specify the language you need to
support in its "Language" property, the VS2003 IDE will generate the
multiple language support resource file respectively.

But in your case, to specify the project's "Culture" property is in order
to tell the VS2003 IDE based on which language locale to compile your MFC
project's resource, it is different with the general .NET application.


Thanks for your understanding!

Gary, I don't think I actually did understand you. Sorry. Please see

So what would I select if I wanted to support Japanese, Chinese and Korean?

So I'd need to build my app three times with a different setting each time
to support Korean, Chinese and Japanese?

I'm doing my best.

Hi Michael,

In a .NET WinForm application, you may set the target Form's "Localizable"
property to "True", then select the languages you want to support in the
above "Language" property's drop-down listbox one by one, each time you
select a language in that listbox, the VS2003 IDE will generate the
corresponding language support resource file for the project.
So I'd need to build my app three times with a different
setting each time to support Korean, Chinese and Japanese?

It depends on do you need to produce the specific language version
application, if yes, you may need to build your project 3 times with the
different culture setting respectively. If not, I suggest you can use the
general convention in such scenario, create the resource only DLLs for your
application to support the multiple languages, please refer to the
following MSDN KB and sample links for details:

Hi Gary,

Thanks for the reply. We are still not able to get Kanji characters to
display, even when setting the culture to Japanese in the resource settings.
The only way we have found that we can get anything to work is to create an
explicit font using one of the various CreateFont routines and use SetFont on
the control, for example:

CClientDC dc(this);
CFont font;
VERIFY(font.CreatePointFont(120, _T("MS Mincho"), &dc));
m_cEdit.SetFont(&font);
font.DeleteObject();

....though it seems that the act of creating the font is the important thing.
The parameters don't seem to make much difference, even the font typeface or
height. Please note we are not storing these Kanji strings as resources.
They are input by the user via a programmatic interface and then passed
through the application for eventual display in various controls. The
application is otherwise English. So we are not trying necessarily to
retarget the application at any one language. We are simply trying to get
the controls to properly display an MBCS character string, in this case
Japanese. At any rate, we did not have to have this font code in our 6.0
version, but now we seem to need it in order to get this functionality to
work with 7.1. Any additional ideas or comments on this? Thanks!

Hi,

I am glad to know you have already found the resolution to your problem, I
tested with a simple MFC6 dialogbox program, setting the culture of its
upgraded VC7 project worked for me, it appears we don't have a similar test
case:(


Thanks for sharing this useful tips with us!
