Hi,
how to conver char* into BYTE* in C++
Regards
|
|
|
|
|
Short (and dangerous) answer: with a cast, for instance
char * myCharPointer ="hello";
BYTE * myBytePointer = (BYTE *) myCharPointer;
A better answer may follow a more detailed request.

of course, you're looking for devil every where :p
a char* is not always a string 
char c = 'c';
char* pc = &c;
BYTE* pb1 = (BYTE*)pc;
BYTE* pb2 = reinterpret_cast<BYTE*>(pc);
BTW, looking at the level of the question, i think it's worth saying that a char IS a BYTE:
char c = 'c';
BYTE b = c;

of course.

Nope. As you know (I know that you know ), char is a signed integer ranging from -128 to 127, while a BYTE is an unsigned integer ranging from 0 to 255.

but you're already going to far by interpreting the bits pattern.
a BYTE is 8 bits, which is exactly what a char is supposed to be too.

Duty sir, duty.

float and int (even pointers!) have the same size on 32 bit systems but we usually don't consider them being the same.

Something like:
<br />
BYTE* pByte = reinterpretcast< BYTE* >( pChar );<br />

quite... reinterpret_cast is the correct word ^^
BTW, i didn't try, but wouldn't static_cast just work here ?
|

Right you are, I knew that looked wrong somehow. I don't think static_cast works on pointers even when there are in fact a type match as these probably would be. Would have to try it to be sure.

A static_cast won't work.

A BYTE is nothing but an unsigned char. If you do the math, that would tell you that the conversion may result in data loss, depending on the value stored in the char variable. The following situation may be an example:
char p = -23;
int i;
BYTE b;
|
|
|
|
|
To be very picky you don't actually loose data, as it's still an 8-bit value. It's just that the semantics change, your -23 = 11101001 gets reinterpretted as 233 = 11101001.

I wanted to use a Console Window to output some debug information for my MFC application, that all works fine, but would like to make the Window a bit larger without having to modify the properties of the Console WIndow by hand each time.
I tried this bit of code as the Console was being created - but did not work.
AllocConsole();
m_hConsole = GetStdHandle( STD_OUTPUT_HANDLE );
int handle = _open_osfhandle( (long) m_hConsole, _O_TEXT );
m_fConsole = _fdopen( handle, "w" );
dwSize.X = 120;
dwSize.Y = 50;
SetConsoleScreenBufferSize(m_hConsole, dwSize);
Any sugegstions please
Andy.

Hi,
on WinXP the layout tab of the console allows you to modify its buffer and window size, and
to make these changes permanent for all future console windows with the same title.
on Vista the option is gone, it just always does it that way.
So for both: do it once manually, then keep the title constant.

Hi there
I have a Some Question
When I Get Logon UserName , I try to use GetUsername Function
But, Function retrieve Name that is "SYSTEM"
Why are retrieve "SYSEM" user name?
|
|
|
|
|
|
TCHAR infoBuf[INFO_BUFFER_SIZE]; //Account Name
DWORD bufCharCount = INFO_BUFFER_SIZE;
if(NULL == GetUserName(infoBuf, &bufCharCount) )
{
DWORD dwRet = GetLastError();
}
thats all;

The GetUserName function retrieves the user name of the current thread.
Try the NetUserGetInfo() function retrieves information about a particular user account on a server or NetWkstaUserEnum
Hope this helps
