Hi all, hope everyone had a good Easter break.

Got an on running problem and still having issues resolving it. I posted a
few months back but didn't seem to resolve the issue. The background to the
problem is that i HAVE to identify an dialog by it's caption. We have a
convoluted system which is too far down the development path to change. The
system needs to close a particular dialog box created by a MS dll. The
Windows class name is not sufficient to identify the dialog (#32770) and so
I have to enumerate all windows looking for a particular caption. This
system works fine until the software is deployed on non-English platforms,
where the caption changes according to the language being used. After
searching MSDN, we have found that there are approximately 26 core languages
that are supported by MS and which cause the caption to change. So far, we
have got all of the roman-based ANSI versions and copied there captions into
a resource file. The software basically gets the system local and then
looks up the corrisponding caption for comparission. Again, this works
fine, our enum call-back looks like this:

BOOL CALLBACK Main::EnumWinProc(HWND hWnd, long lParam)
{
char cCaption[255], cClassID[255];
GetWindowText(hWnd, cCaption, sizeof(&cCaption));
GetClassName(hWnd, cClassID, sizeof(&cClassID));

AnsiString sStoredCaption;
// Load caption from string table resource based on system local

if ((strcmp(cClassID, "#32770")==0)
&&(strcmp(cCaption, sStoredCaption.c_str())==0))
{
PostMessage(hWnd, WM_CLOSE, 0, 0);
return FALSE;
}
else
return TRUE;
}

The problem that I'm having now is dealing with platforms that use
non-roman, Unicode strings i.e. Hebrew and Russian. On these systems, i can
get the caption but i seem unable to store it in my string table along side
the other ANSI captions (I get a resource compile error).

My first question is, how can i store these string in my string resource?
Do i need to convert them to escape characters first?
My second question is, how do i modify the above call-back so that it can
work with either UNI or ANSI without having to compile separate versions -
I'm trying to make something generic that will work seamlessly on both
platforms.

I hope this makes sense,

Many thanks in advance,

Mike Collins

Hi Mike,

Have you tried using TCHAR instead of the familiar "char" and LPTSTR instead
of LPSTR or "char*"?

Both TCHAR and LPTSTR can handle either a char or a wchar, depending on the
way the project is compiled. Not sure if that will solve your problem, but
we've started using that in all of our code to reduce possible problems down
the road.

As for easy "escape characters" to convert from ANSI to UNICODE, I asked
this some time back and was told that there really isn't a good one-to-one
conversion for it.

If you must play with something, the closest functions you are going to find
are WideCharToMultiByte and MultiByteToWideChar, but they don't work all the
time.

HTH,
~Joe

In addition to what poojo have said

Here are some precisions with UNICODE vs MBCS

Thanks bob, thats pretty much as i though i.e. us the W api calls. But how
do i store the captions in resource file. At the minute, if i paste a
UNICODE caption into my resource stringtable i get a compile error. Do i
need to conver the UNICODE values into escape values first and then paste
them into the resource. I believe i have a linux utility that will do this
for me...

Bingo - thats what i was looking for.

I need to convert to escape characters and then preceed it with an L, there
after, i should be able to interchange between the wide string and ansi
string accordingly.

Thanks for the help

Mike
