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.

So does Depends also use said .map file, or how does it generate the function's signature?

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

F:\>undname -f ?ConcatInPlace@CString@WTL@@IAEXHPBD@Z

UNDNAME Version 5.00.1768.1Copyright (C) Microsoft Corp. 1981-1998

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

Thanks Mike, but that's undname, not Depends.

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...

Sorry the code is not working for maximize button

its fairly working with close button

U can add

ModifyStyle(WS_MAXIMIZEBOX,0);

or remove maximize button by

ModifyStyle(0,WS_MAXIMIZEBOX);

u can see the disable maximize button, if teh minimize button is also present, else it will hide the maximize button disabling.
I think that is the default windows behaviour.

I donno how to change it Frown | :(
