Hello all. I want read/write the CMOS in Windows NT or later. I've knew that is necessary use a driver. Then I would like to know if there is a driver of the Windows that I can call, so that I don't need develop a driver?

Thanks all.

I would like to open MS Word 2003 via api and send text to it. After that the user should edit the text in word and I would like to catch an event when the document is saved. Would like to do this via com. All examples I found about this belong to office 97 and doesn't work anymore. Does anyone can tell me where to find an example for automation in Office 2003?

I think you can use Microsoft Word Object library for the same.

open OLE viewer provided with visual studio tools and open the interface tab.
you can find the requried one there.
I think codeproject has some article on the same.
Pls check it.

it is not depends on VC++ 2003 or VC++ 6. u can use either.

Is there a way that we can know all exposed functions and their signatures and exposed data items which dlls and lib files expose, if we donot have any documentation about them, something like resource hacker.

You can use DumpBin[^] utility provided by Microsoft. This is console based application

You can use "Dependency Walker" which is provided with Visual Studio tools for the same purpose.

While dumpbin and depends can show the export table, they will not show you the function signatures.

If functions are exported as mangled C++ names, Depends can translate those into C++ prototypes.

Yes, because all that info is encoded into the mangled name. For example:

?ConcatInPlace@CString@WTL@@IAEXHPBD@Z becomes:
protected: void __thiscall WTL::CString::ConcatInPlace(int,char const *)

I just pulled that from a MAP file of one of my apps. I was just demonstrating that the mangled name contains all the info necesary to convert it to a C++ prototype.

It's all encoded in the mangled name. You can see for yourself using the undname tool in the PSDK:

converting a "character" into hexadecimal

hi friends,
i'm reading one "character" at time from RS-232 interface and storing it in a character array.I'd like to know whether any in-built functions are there to convert this "single character" into its ASCII hexadecimal eqivalent??
Thanks in Advance...

Hexadecimal equivalent is not something very clear. What do you want to do ? Print this value in a string (using its hexa representation) ?
If yes, you can use printf with the 'x' tag:

char szString[50];
char Temp = 'A';
sprintf(szString,"%x",Temp);

Because a number is neither hexa, decimal nor binary, it's just its representation that can change.

EDIT: changed printf to sprintf, thanks David Smile | :)

For what purpose? Usually when someone talks of converting from base-10 to base-16, it is for display purposes. When a number is stored, its base is irrelevant. In other words, 123, 0x7b, and 1111011 all represent the same number.

I was about to ask if you are working for the company I use to work for (the only one I know that uses RS-232 and transmits data at twice its size), but then I saw you are in India ...

Anyway, to answer your question:

To convert a number to a text-readable ASCII-Hex representation (that is, each half of a byte is represented by a single hexadecimal character [0-9aA-fF]), use the printf family:

char buffer[100] = {0};<br />
BYTE myInfo = 64;<br />
sprintf(buffer, "%X", myInfo);

To convert an ASCII-Hex number back to a byte, use sscanf:

char* buffer = "AB";<br />
BYTE myInfo = 0;<br />
sscanf(buffer, "%2.2X", &MyInfo);

If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

Perhaps this helps?

BYTE HexToByte(LPCSTR cpHex)
{
  BYTE cRetVal;

  if (*cpHex < 58)
    cRetVal = *cpHex - '0';
  else
    cRetVal = *cpHex - '7';

  cRetVal <<= 4;

  cpHex++;

  if (*cpHex < 58)
    cRetVal += *cpHex - '0';
  else
    cRetVal += *cpHex - '7';

  return cRetVal;
}

onwards and upwards...
