When I used the C++ builder's tool named coff2omf.exe to
transform the COFF lib to OMF lib ,I find that the former
204 k file has change to 512 byte.why??

What system calls under MFC do you need to make to determine how many colors are being used by the system?
I am trying to determine hoe many colors are being displayed with the current settings (ie the number of colors you pick when you right click on the desktop and select Properties...Settings...Colors)
I want to set the background color and font color for a dialog box, but only if the user is running at least 16 bit colors because it looks like crap on a 256 color display.
I'm going to live forever or die trying!

Create a device context and use GetDeviceCaps().
CClientDC dc(NULL);
int bitdepth = dc.GetDeviceCaps(BITSPIXEL); This will return the number of bits per pixel the screen is currently using.
Hope this helps,

Super nice!
Thanks.
I had another question on this:
Is this bulletproof or is it a heuristic?
Is there no OS level call to get this information?
Just curious - your answer works perfectly.

It will always work for the primary display. If you are using multiple displays, you'll need to use EnumDisplaySettings() as pointed out in another answer. Use ENUM_CURRENT_SETTINGS to return the current settings. The dmBitsPixel member of the DEVMODE structure will give the number of bits per pixel:
DEVMODE dm;
dm.dmSize = sizeof(DEVMODE);
EnumDisplaySettings(lpszDeviceName, ENUM_CURRENT_SETTINGS, &dm); lpzsDeviceName is the name of the device (returned by EnumDisplayDevices()), or NULL to use the primary device.
Hope this helps,

Ha! So, I was late, but I was more right! ;P (is that even possible?  ) You were just more exact, providing example code.

I've got to get to 1K somehow, eh?
I bet if we continued this, Chris'll probably not be too impressed. Then again, this thread is buried deep in some obscure forum.
:looks up, checks the forum title: "Visual C++":
Doh! :homerdoh:
(someday, Chris'll put in a homerdoh smiley... but I figure he's got enough of his plate already).

You just answered another question I had - nameley what driver name do I use? I was looking at examples and they used device names of "Epson" and I was like Moe on the Simpsons when I saw that "HuuuuuuuuUUUUUUUUUHH?!?!?!?"
Many thanks (and to you to Atlantys)!

Try: EnumDisplaySettings, and check the dmBitsPerPel member of the DEVMODE structure.
It's all in the MSDN.
"dmBitsPerPel
Specifies the color resolution, in bits per pixel, of the display device (for example: 4 bits for 16 colors, 8 bits for 256 colors, or 16 bits for 65536 colors). Display drivers use this member, for example, in the ChangeDisplaySettings function."

Some guy here in codeproject (I don't remember who and I can't find the post either) posted the following link
http://download.microsoft.com/download/b/d/c/bdccea1b-96d9-4ad9-8045-56619af95835/qtr40enud1.img, which is the link for the 1st MSDN 2003 CD image file. As you can see the file has an img extension. There are three of these files and I downloaded the first one. There is no program in my computer that recognizes these image files. I thought that the CD-Writer software (Roxio Easy CD Creater) would take care of it, but it didn't. Can anyone help me with this problem? Can one tell me the link to the MSDN 2003 download site? I tried searching on MSDN but I could not find anything about downloading MSDN 2003. I am sure that there are directions there on how to proceed after you download these image files, but I can't find anything.

Use Nero to burn the image. http://www.nero.com/en/[^]

Nero, doesn't work either. It does not recognize the file format. Roxio Easy CD Creator and Nero are the only two CDW programs that I have access to. I checked the header of the file and it doesn't have any information on it at all. It's all zeros.

That's weird!
I'm going to go ahead and use the ole programmer's saying: "It worked fine on my machine!"
I was able to burn the images easily. Sorry that I can't be any help

Rename them to .iso. They are the same file format, just with a different extension.

Ryan and Atlantys, thank you very for your help. I am performing a write simulation right now on the image and since Nero is not giving me any errors yet, I am assuming that everything is working fine. So both of your suggestions work.
Well, it works like a charm. I opened the file with WinRar as well and everything looks great. Thank you, thank you, thank you.
I got so upset last night because I dowloaded the first image using a 49k connection and it took me several days, only to find out that I couldn't open the file. Looking forward to 10 more days of downloading MSDN 2003.

It took me 45 mins to download most of it, but then I found out I was running out of disk space, so I had to cancel the download.
