Is this problem reproducible on other systems with different graphics drivers?
I ask because I was having a problem with toolbar button icons (for example, in IE and WinZip) with a previous version of nVidia's drivers with this system's Riva TNT card. Reverting to the version on the XP CD fixed it. The latest drivers appear to have fixed the problem.
Unless you can reproduce it on a number of other graphics cards/drivers, I'd blame it on the graphics manufacturer.
You could also see if it goes away if you reduce the hardware acceleration level.

You may want to try ExtractIconEx, passing the actual resource ID to load. An excerpt from the docs:
nIconIndex
Specifies the zero-based index of the first icon to extract. For example, if this value is zero, the function extracts the first icon in the specified file.
If this value is –1 and phIconLarge and phiconSmall are both NULL, the function returns the total number of icons in the specified file. If the file is an executable file or DLL, the return value is the number of RT_GROUP_ICON resources. If the file is an .ICO file, the return value is 1.
V NOTE THIS SECTION V
Windows 95, Windows NT 4.0, and later: If this value is a negative number and either phIconLarge or phiconSmall is not NULL, the function begins by extracting the icon whose resource identifier is equal to the absolute value of nIconIndex. For example, use -3 to extract the icon whose resource identifier is 3.
Once the array of icons are loaded, you can simply pick index 0 for 8 bit, index 1 for 16 bit, index 2 for 24 bit, etc.
onwards and upwards...

As I read it, this won't help. The ExtractIconEx gets the icons from a file. A big and small icon for
each ICON. He can already load a particular dimension of icon from his own files using LoadImage.
What he needs to do is to pick a particular colour depth icon, when a ICON may have icons with the same
dimensions, but differing depth.
Unless I'm wrong. It's not *my* question to start with after all!

I have created a 3D model and want to include a light source,
after I created it, the colour of the whole model changed to one colour...
moreover, the light source was not fixed in one position and changing all the time...
can anyone pls tell me how to fix this and provide me some examples??
thx very much~~

Hi,
I am looking for icons of different flags (spain, germany etc...)
Can anyone assist me in finding them?

You might not have them installed, but they're definitely supplied with VS6 and both VS.NET versions.

I'd like to find the tutorial of using it Step-by-Step. About Rich Edit, serialization of data in this ctrl etc.

Sir,
how can i get the processor's or Mainboard's serial no. Kindly guide me as soon as possible.
Regards,
Kashif Mughal

I'll leave the easy one to someone else;
To get the mainboard's serial number, power off, open the case and look on the biggest board you can see for anything that looks like a serial number.
Write it down.;P

Well, it's Friday...

Not sure about the processor's serial number (does it have one?), but the system board's serial number can be obtained from the Win32_BaseBoard class.

I believe that P-III and later processors have serial numbers 'etched' into them, although it is possible to switch off or mask the ability to retrieve the serial number, normally in the BIOS. Don't know about AMD processors though.

Ahh yes. I seem to remember that discussion causing so much stink in the "privacy" department.
Thanks.

hi:
Recent there are some problems boring me ,which is how to read the CD_ROM sectors.As we all know ,there are three track mode. The first one is CD_DA ,which is Audio CD ,The second one is MODE1 ,the last one is CD_ROM XA ,which is MODE2 and has two form.
Now I can read the sectors which track mode is MODE1 or MODE2form1 with CreateFile and ReadFile API,but can't read other track modes with them. I want to read the sectors which track mode is ANY ONE with DeviceIOContrl and IOCTL_CDROM_RAW_READ,but I can't read anything.
This is my code.
hCD = CreateFile ("\\\\.\\H:", GENERIC_READ,
FILE_SHARE_READ|FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
NULL);
lpSector = (unsigned char *)VirtualAlloc (NULL, dwSize,
MEM_COMMIT|MEM_RESERVE,
PAGE_READWRITE);
RAW_READ_INFO Info={0};
Info.DiskOffset.QuadPart=0;
Info.TrackMode=XAForm2;
//Info.TrackMode=YellowMode2;
//Info.TrackMode=CDDA;
Info.SectorCount=1;
DeviceIoControl(hCD,IOCTL_CDROM_RAW_READ,&Info,
sizeof(Info),lpSector,2352,&dwNotUsed,NULL);
Now the DeviceIoControl return 0,and there is no data in the lpSector
and my friend suggest me that I should use DeviceIOContrl and IOCTL_SCSI_PASS_THROUGH_DIRECT,but using them will bring a lot of questions
another question is how to differ the track mode.
Thank you very much
Regards

Which means the function failed. What does GetLastError() return at that point?

You have something like:
if (DeviceIoControl(...) == FALSE)
DWORD dwError = GetLastError();

Hey all.
I am working on a dialog based app that has a menu in it. I've set some mnemonics on the buttons, such as "&Stop" and so on. When the program is run, the mnemonic shows up for the buttons perfectly fine ... ie Stop .... However, it is not doing this for the top menu. I created a menu, all it really has now is "&Options" and under that "&Configure". The only way I can get the mnemonic to show for the menu is by pressing the ALT key. As soon as I do that, the mnemonic shows up right away for the menus just fine.
If you are programming in VS .NET 2003, the IDE has the mnemonics for the menus showing at all times. I am wondering how that I can tell my menu to show the mnemonics all the time, not just when someone is pressing the ALT key. I've checked the menu properties and such but I can't seem to figure out how to do it.
Thanks!

I think it's a setting of your desktop. At least that's how it works for buttons and other dialog items. I can always see mnemonics for menus.

Usability bug in VS.NET - it's not following the user's preferences.
On Windows 2000 and XP, the default is not to show the underlines. If you want to turn this feature off on XP, right-click a blank area of your desktop and choose Properties, go to the Appearance tab and choose Effects. In the Effects dialog, uncheck Hide underlined characters for keyboard navigation until I press the Alt key.
To be fully compliant, you should hide your dialog mnemonics until you get a WM_CHANGEUISTATE message. Note that the Internet Options dialog in Internet Explorer does this (at least, for IE 6.0).

Get/SetCommState with its DCB structure should be enough, handling COMMCONFIG, COMMSTAT, COMMTIMEOUTS you can control almost everything on a serial port
|
|
|
|
|
But there is always a start bit and a stop bit present at the serial port. Is there a need to write in the "synchronosation clock" for synchronization purposes?
Actually my data is an analogue voice signals that has been convert to digital form using a PCM codec(hardware use with synchronisation). This digitised stream bits of "raw data" is to be received at the RS232 port.
Is there any alternatives to run a simulation test at the serial port to see whether it receive any "raw data", apart from using a signal generator?

Start and Stop bits, framing, and parity are all handled by the UART hardware; you don't need to be concerned about them other than to set your preferences at each end of the comm channel. Since hardware handshaking has gone out of style, serial comms are essentially asynchronous - you can't depend on port timing for real time use.
What you can do is set your sampling hardware to a defined sample rate less than the serial port rate, and buffer it in case there are delays that prevent a sample from being read by the host machine before the next sample is taken. I believe that modern uart chips have a built-in 16-byte buffer, and that may be adequate for your purposes.
On the host machine you can simply read the data continuously from the serial port and pass it to a buffer. A separate thread can read the buffer and process the PCM data.
For simulation purposes you might write a test program that uses COM1 to output a block of data at a slow rate, and COM2 to read data at a high rate, with a null modem cable between the two ports.
Heard in Bullhead City - "You haven't lost your girl -
you've just lost your turn..." [sigh] So true...

the uart chips are not designed for these experiments, maybe you can read the bits on the parallel port (of course you must develop a specific driver)
