Terry O'Nolley20-Jul-03 15:04 Terry O'Nolley 20-Jul-03 15:04  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! Re: How do you get the number of colors displayed? Ryan Binns20-Jul-03 15:44 Ryan Binns 20-Jul-03 15:44  Create a device context and use GetDeviceCaps(). CClientDC dc(NULL); // Screen device context int bitdepth = dc.GetDeviceCaps(BITSPIXEL); This will return the number of bits per pixel the screen is currently using.

Is there no OS level call to get this information? Just curious - your answer works perfectly. I'm going to live forever or die trying! Re: How do you get the number of colors displayed? Ryan Binns20-Jul-03 16:30 Ryan Binns 20-Jul-03 16:30  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.

Atlantys20-Jul-03 15:47 Atlantys 20-Jul-03 15:47  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."

[Rich Cook] MSDN 2003 Toni7820-Jul-03 13:32 Toni78 20-Jul-03 13:32  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. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie Re: MSDN 2003 Atlantys20-Jul-03 14:50 Atlantys 20-Jul-03 14:50  Use Nero to burn the image. http://www.nero.com/en/[^] Toni78 wrote: Roxio Easy CD Creater I prefer to wear gloves when using it, but that's merely a matter of personal hygiene [Roger Wright on VB] Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots.

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.

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. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie Re: MSDN 2003 Ryan Binns20-Jul-03 16:31 Ryan Binns 20-Jul-03 16:31  Toni78 wrote: Thank you, thank you, thank you.
