I am wondering if the VC compiler uses multiple threads in compiling source code, i.e. will compilation speed scale linearly with number of processors?

when i create a project following the wizard, I may find
the final installation files include all the files i put
into the file group of this project such as my exe file,
my icon file and so on.
Someone told me I can create a single setup.exe file by
using the tool PackageForTheWeb of installshield, but I
still want to know how can i create a project only include
some installshield stardard files (i.e. data1.cab,
licence.txt, setup.exe and so on) just like some other
softwares. I think all my own program files should be in
the data1.cab, shouldn't it?
Thank you.

Why don't run the same programe code on vc++ compiler,but it is run good on dev-c++ compiler.
The code is
#include "stdafx.h"
#include <windows.h>
LRESULT CALLBACK WindowProcedure(HWND, UINT, WPARAM, LPARAM);
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,

//wincl.cbSize = sizeof (WNDCLASSEX);
wincl.hIcon = LoadIcon(NULL, IDI_APPLICATION);
//wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);

wincl.cbClsExtra = 0;
wincl.cbWndExtra = 0;
wincl.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
if (!RegisterClassEx(&wincl))
{

No-one is going to wade through your code if you don't even say what the error is, but VC6 is one of the worst compilers for C++ standards conformance.

LOL - so the compiler works fine then. If it works with your other compiler and runs, chances are it's inserting a workaround for a function you're calling that is NT only. Or your build settings are creating the problem.

I can see that, I'm not stupid.

Well, this code:
if (!RegisterClassEx(&wincl))
{
MessageBox(NULL,TEXT("this program required windows nt!"),
szClassName,MB_ICONERROR);
return 0;
}
seems to be your problem. Now, I presume this means you got the code from somewhere else, if you couldn't work out that this is the source of your dialog, and you blamed the compiler. Either way, your window class is failing to register.

VS.NET 2003, but I've written lots of Win32 code in VC6.

W2000 IS windows NT. Your message box seemed a bit odd to me. OK, in that case, you need to figure out why RegisterWindowEx is failing.

Call GetLastError() when the function fails, and instead of showing a MessageBox saying "This program requires Windows NT" or whatever, show a messagebox with the error code GetLastError() returns. Then post the error code here.

So ?
Where did you get the starting code from ? It's obvious you did not write it. What are you trying to achieve ? I think you need to do some console programming first and learn enough about C++ to understand the difference between compile time and run time errors. That is friendly advice, not an insult.

That's what I was scared of. You *can't* learn programming windows in C++, until you know some C++. You have the Petzold book ? You're doing things the hard way, you should probably use MFC if you're going to use C++.

I have a few comments to make.
1. Format your source code because nobody will go through it and read it the way you have posted it. It's a mess. To learn how to format your source code so it would display properly read the Frequently Asked Questions section on this page.
2. Judging from your current and previous posts, I suggest that you read some Windows 32 Programing books or tutorials. Here is a website just for a start http://www.winprog.org/tutorial/
3. The answer to your question.
You can't comment out the parts where WNDCLASSEX's members are being initialized. You need to initialize all the members to their appropriate values. So comment out
//wincl.cbSize = sizeof (WNDCLASSEX);
//wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
to
wincl.cbSize = sizeof (WNDCLASSEX);
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
and you program will run fine.
// Afterall I realized that even my comment lines have bugs

wow. As you say, it was very ugly and so I only skimmed it, but I'm still amazed I missed an error like that !!!

I still like your signatures. 
Come on, everyone would have missed those errors! It's the format. It was just pure luck for me to spot comment lines at a place where they normally shouldn't be.

Just to reiterate - Petzold style Windows programming is more complex and more difficult than MFC. Very few people do it that way today. MFC is not perfect, but it's a lot easier than what you're learning, and if you persist in trying to learn from the Petzold book without first learning C++, you will never become a programmer.

Hi there,
I want to rotate an image and then save it in a file using GDI+. Is that possible? I don't want to draw the rotated image.
Thanks!

Hi
if you want to make a simple rotation (90, 180, 270 or flip), you can use :
pBmp->RotateFlip(Rotate180FlipNone);
// Rotate180FlipNone is an exemple
if you want to rotate it, use this
Bitmap* Rotate ( Bitmap* pSrcBmp, REAL rRot )
{
int w = pSrcBmp->GetWidth();
int h = pSrcBmp->GetHeight();
Bitmap* pDstBmp = new Bitmap( (w+h)*2, (w+h)*2, PixelFormat32bppARGB );
// (w+h)*2 max width and height, you can optimize it(?)
Graphics graphics(pDstBmp);
graphics.Clear(Color(0,255,255,255));
Pen pen(Color(255, 255, 0, 0));
graphics.TranslateTransform((REAL)w+h, (REAL)w+h);
graphics.RotateTransform(rRot);
graphics.DrawImage(pSrcBmp, 0, 0);
return pDestBmp;
}
save this image with
{
GetCodecClsid(L"image/tiff", &mClsid);
// you can use L"image/jpeg", L"image/gif", ...
pBmp->Save(L"img.tif", &mClsid);
}
int GetCodecClsid(const WCHAR* format, CLSID* pClsid)
{
UINT num = 0; // number of image encoders
UINT size = 0; // size of the image encoder array in bytes
ImageCodecInfo* pImageCodecInfo = NULL;
GetImageEncodersSize(&num, &size);
if(size == 0)
return -1; // Failure
pImageCodecInfo = (ImageCodecInfo*)(malloc(size));
if(pImageCodecInfo == NULL)
return -1; // Failure
GetImageEncoders(num, size, pImageCodecInfo);
for(UINT j = 0; j < num; ++j)
{
if( wcscmp(pImageCodecInfo[j].MimeType, format) == 0 )
{
*pClsid = pImageCodecInfo[j].Clsid;
return j; // Success
}
} // for
return -1; // Failure
}
