I want to read CMYK color mode TIFF file
and save CMYK color mode TIFF file
if I transform CMYK TIFF file to RGB file .
then color information will change .
(I use photoshop for testing)
So I want to dispose CMYK TIFF file in CMYK color mode .
no transform .

get yourself a copy of LibTiff. with it, you can read and write the TIFF data directly.

Yes ,I have used Libtiff .
but it has the same quesiton .
Don't dispose correctly CMYK color mode Tiff Image
I need read and write CMYK color mode Tiff image .
and I have tested CXimage class that downloaded from http://www.codeproject.com/bitmap/cximage.asp
It supports Tiff file ,but there is a problem that It supports CMYK color mode tiff image.
and FreeImage Library ,download from
http://www.codetools.com/bitmap/graphicsuite.asp
it uses Libtiff library .but I find that there is the same problem of supporting CMYK color mode tiff file .
I don't know how to do
help me
Thank you

Is there a getclientrect() member function? Just a guess....

GetClientRect returns just the client area. GetWindowRect returns the area of the entire CWnd object. See API docs for CWnd.

#define RectWidth(lprc) ((lprc)->right-(lprc)->left)
#define RectHeight(lprc) ((lprc)->bottom-(lprc)->top)
RECT rc;
int width,height;
GetWindowRect(hwndRichEdit,&rc);
width=RectWidth(&rc);
height=RectHeight(&rc);

I'm curious as to why you would do it that way. This is not a criticism, just a curiosity.
Why couldn't you just use CRect instead? Also, why are you using the globally scoped GetWindowRect rather than the CWnd GetWindowRect? Is there a benefit to doing it that way?
Here's the way I would do it:
int width = 0, height = 0;
CRect rect;
GetWindowRect( rect );
width = rect.Width();
height = rect.Height();
Thanks.

Maybe he isn't using MFC/WTL or doesn't want to force that dependency on others.

I'm writing a Winsock application, and I heard that the only way to learn how is browse through the mucky muck of Winsock code. So that's what I did. I'm writing a program based upon Essam Mohammed El-nagar's and I got my program to interact with his server.
Trying to re-write his server is more difficult than I expected though. I've done everything noticable that he had, however whenever I run it, it gets a binding error. His does not. Is there some stupid little line of code that could fix this?
If you care enough to look into my source code I'll upload it on request. Thanks a bunch.

I have been trying to write a function in VC++ 6.0 on setting
the setprecision and setw in a function. This is roughly how I intend to do ..
my_set_function(int precision,int width)
{
setprecision(precision);
setwidth(width);
}
fstream io("abc.dat",ios::out);
.
.
double abc=1.234566,bcd=2.3456;
.
io << my_set_function(3,5) << abc << my_set_function(2,4) << bcd;
Since I want to set it for every variable, I hope to do it in a
neater and shorter manner.I know this code is not a functional one , hope someone have some idea of what I am trying to do?
THanks a million!

If you want to write a manipulator that works for all types, including those that you did not define, then you'll need it to work in tandem with a stream of your own writing, which can very well be simply a stream that uses a normal stream, but applies your manipulator.
Read my articles here on CP in the STL section for info on parameters in manipulators, and writing custom streams.

Thought of playing around abit with OpenGL. Checked codeproject and found some examples.
The annoying thing though is that for some reason I have some lib clash:
a __ftol2 refernce is in one of the opengl libs and can't be found.
I'm using VS6SP5 and latest SDK
Any ideas?

Hi,
I'm currently writing a method that is supposed to shape a region according to a color pattern in a supplied image. To do so I iterate through all the pixels in the image, but when I'm nearing the end, no matter the size of the image, I get an "First-chance exception in ImageRegion.exe (GDIPLUS.DLL): 0xC00000FD: Stack Overflow." exception. I'm new to GDI+ and I can't figure out what I'm doing wrong...
The method looks like this:
HRGN CRegionFromImage::FromFile( const WCHAR* filename, Color color )
{
HDC hDC = ::GetDC( NULL );
Graphics g( hDC );
Bitmap* bitmap = Bitmap::FromFile( filename, FALSE );
if ( bitmap == NULL ) return NULL;
Rect rect( 0, 0, bitmap->GetWidth(), bitmap->GetHeight() );
Region region( rect );
BitmapData* bitmapdata = new BitmapData;
bitmap->LockBits( &rect, ImageLockModeRead, PixelFormat32bppARGB, bitmapdata );
UINT* pixels = (UINT*)bitmapdata->Scan0;
for ( UINT y = 0; y < bitmap->GetHeight(); y++ )
{
for ( UINT x = 0; x < bitmap->GetWidth(); x++ )
{
Color pixelcolor( pixels[y * bitmapdata->Stride / 4 + x] );
if ( color.GetR() == pixelcolor.GetR() && color.GetG() == pixelcolor.GetG() &&
color.GetB() == pixelcolor.GetB() )
{
Rect xorrect( x, y, 1, 1 );
region.Xor( xorrect );
}
}
}
bitmap->UnlockBits( bitmapdata );
delete bitmapdata;
return region.GetHRGN( &g );
}
Thanks,
biff

Hello Everybody:
I was wondering if someone can tell me how I can play a wave files in MFC. Or if there is any other way to do it. Thanks and hope to hear from you guys soon.
Have a good day!!

Take a look at the PlaySound function in the MSDN, it can play wave files for you. There's many ways to do it, but PlaySound is one of the simplest.

Hello. I need to kill a thread when a dll is unloaded (in DllMain). However, the OS would not let ExitThread to return as long as any other thread is in DllMain, and I have a deadlock.
Any hints?
And yes, I've tried DisableThreadLibraryCalls. Doesn't work

Short answer is never do that.
Step back, rub your eyes, take a deep breath, stretch a bit, and reflect on the relative importance of CP, CG, the age / travel time sustained by supposedly 'fresh' cheese curds, and Life in General. - Shog9

Easy to say. I have a static (read global) variable in this DLL that launches a thread, and in its destructor I need to kill this thread. The problem is that the destructor is called in DllMain.

Ok the question is - who calls FreeLibrary?
You should provide the client with calls that shutdown the thread.
