Subject: Precompiled headers for both C and C++
Environment: MSVC 6.0 (sp1) Win NT 4.0 (sp4)
Hello,
I have a project with a lot of C files and a lot of C++ files.
I have not found a way to have precompiled headers for both of the
file types in the same project.
Does anyone know how to do this, if it is possible ?
Best regards,
Mats

I have also had problems when appending a CString object to another =
CString.
This works however:
CString csString, csDestination;
csDestination =3D "Hello";
csString=3D " World!";
csDestination =3D csString; // FAILS!?
csDestination =3D (LPCTSTR)csString; // WORKS!!
I don't know why.

You can set a window to stay on top by using:

cbRead is the correct value (256, as I am doing a 256 byte read), and I
have traced through the CString source, and it fails on the 2nd memset
within ConcatCopy.

I did, here's what I found...
void CString::ConcatCopy(int nSrc1Len, LPCTSTR lpszSrc1Data,
int nSrc2Len, LPCTSTR lpszSrc2Data)
{
// -- master concatenation routine
// Concatenate two sources
// -- assume that 'this' is a new CString object
int nNewLen = nSrc1Len + nSrc2Len;
if (nNewLen != 0)
{
AllocBuffer(nNewLen);
memcpy(m_pchData, lpszSrc1Data, nSrc1Len*sizeof(TCHAR));
memcpy(m_pchData+nSrc1Len, lpszSrc2Data,
nSrc2Len*sizeof(TCHAR)); <--- Fails, or appears to do nothing
}
}
This function is called by operator+=
I have no idea what's going on :(

Well slap me silly and call me susan.=A0 It's (not entirely) my =

While I was watching the internals of the function in question throught
the debugger, when the value I was watching did not grow, or change
color when it should have, I instantly assumed it wasnt working.=A0 The
fact is that it was working, and it's in fact a limitation of the watch
window.
=A0
Apparently it has a limit to the amount of text each "box" can contain
(no idea what that limit is), and also, if it overflows this limit, =
it's

change is a bug.

Subject: Localization
Hi all!
I have been given the exciting task of examining all our legacy code (much
of which hasn't changed since our DOS days) and determining what is needed
to support localization. I haven't a clue what's involved in localization,
but since our European and Mexican markets are growing faster than our
domestic markets, I agree that it makes sense (which is not always the case
when a VP decides what the software will do next :->).
Can you fine folks recommend online resources or books which will help lay
the topic out for me? I'll read through the information in MSDN, of
course, so don't bother suggesting that. :-)
Thanks a bundle!

Hi Timothy,
There is an excellent tool called RC-WinTrans for localizing .rc
files. I have been using it for about a year and a half now and I am
very satisfied with it.
I allows me to work with one resource file only. All the
translations are handled by RC-WinTrans. When I want something
translated I export the strings to an Excel file, and send it off to
the translator. When it comes back I import it, and RC-WinTrans
builds a localized .rc file that I can compile into my project.
You can find at http://members.aol.com/ibsdevelop/rct/rctsite.htm

Subject: win api to fade audio
Environment: Visual C++ 6.0 NT 4.0 SP 4
Hi,
I am writing an app that must set up the mixer device to fade volume over a
few seconds.
This is actually the third major version of this software, with the first
being released for DOS about 1993, the second being 16 bit windows in 96 and
now this on Win32. All three version have had to ramp the volume up and down
smoothly without user intervention. The DOS version used "The Developer Kit
For Sound Blaster Series" which was (and I think still is) a full library to
program SB cards from DOS. This contained a function called ctadSetupFade()
which programmed the mixer chip to independantly ramp the volume on its own.
In other words if my DOS program contained the code :-
foo()
{
ctadSetupFade();
ctadStartCtrl(); // actually start the volume fading
while(1 == 1);
}
my program would lock in an infinate loop, but the sound (maybe CD) coming
out of the sound card would continue to fade smoothly. The sound card
proceeding like an independant computer.
The win3.1 version of the software used setvolume() type functions in a
loop. Sometimes it was okay, but other times there would be a message
bottleneck and suddenly all the bunched up setvolume() messages would be
executed very quickly - very messy.
So we know that programming the mixer chip to do a fade on its own over a
certain amount of time is supported by the hardware and we are trying to
find a way of programming it through win32. Does anyone know about this ?
Thanks
Phil.

Hi everybody:
I want to know how to get the scope of the viewport. I used the function

1, lpsize->cy = 1. It seems not right.
I wonder if there are some mistake in my code:
--------------------------------------------------------------------------------

HDC hDC;
LPSIZE pwRet;
..
if (GetMapMode(hDC) != MM_TEXT) SetMapMode(hDC,MM_TEXT);
if (GetViewportExtEx(hDC,pwRet))
{
xClient = wRet.cx;
yClient = pwRet->cy;
..
