Hello,
Is it possible to have translated the MessageBox to show translation for the
Yes and No button ?? ...
if (Application->MessageBox(myLoadString(IDS_LANG1_STRING85).c_str(),
myLoadString(IDS_LANG1_STRING86).c_str(), MB_YESNO) == IDNO)
I have an application that needs to have all the strings translated to
another language (French for example) and need to have the Yes and No button
translated to French.
What will be the best approach to translate the MessageBox strings.
Thanks for your help.

directly, as the button texts depend on the current translation selected in
the OS.
So the solution depends on two things: 1) what translation tool(s) you use
(or plan to use) and, 2) how much work you are willing to do.
The solution I finally settled on was to write a MessageBox() replacement
function implemented in terms of the VCL function CreateMessageBox(). In my
case, I used Localizer to do the actual translation work which, fortunately,
has the ability to translate the resource strings in the VCL. This made the
task relatively simple, for once I had the replacement function written, all
I had to do was use Localizer to translate the text ("Yes", "No", "OK",
"Cancel", etc.), and Localizer then takes care of the loading the
appropriate translation at runtime.
If you don't have a translation tool such as Localizer, then about the only
option you have is to write your own MessageBox function to give you the
kind of flexibilty you need. You may not need automatic dialog sizing, or
all possible combinations of "Yes", "Yes to All", etc., in which case,
writing your own MessageBox should be fairly straight forward.
I am not necessarily advocating Localizer (it works, but it has its quirks
and problems too), but any translation tool worth its salt should be able to
translate the VCL's resource strings. If you have one that can do that,
then a CreateMessageBox-based solution is by far the easiest, IMO.
Good luck,

installed on the end-user's computer, which may not always be the case, or
even desirable. MessageBoxEx is, therefore, only useful if you know (or can
otherwise guarantee) that your program will run on a computer on which that
is the case, but enforcing that requirement on your end-users might not be
practical.
