any idea how we can cast from std::vector types.
e.g.. i am using the win32 API RegQueryValueEx ().
the out buffer it takes should be LPBYTE.
i used the code as shown,
TCHAR * buf = new TCHAR[2];
RegQueryValueEx (.............. .. (BYTE*)buf));
now i want to use a vector instead of TCHAR*.. so what i did is,
std::vector<TCH ARbuf(2);
now i want to use this in the RegQueryValueEx () API, how do i cast it
to LPBYTE... i tried using const_iterator. ... the cast doesn't produce
warning or error, but the results are not as desired. 2 2610 vi*******@gmail .com a écrit :

I don't known about LPBYTE but perhaps it is what you want :
RegQueryValueEx (.............. .. static_cast<LPB YTE*>(&buf.fron t()) );

See Effective STL book.

std::vector<TCH ARbuf(2);
RegQueryValueEx (.............. .. (BYTE*)&buf[0]));

Hi,
I have replaced my BYTE* by a vector<BYTE> and before I used to do :
void CCardRecord::GetRecData(int nOffset, int nDataSize, CString& csValue)
{
BYTE *pTmp = NULL;
pTmp = new BYTE;
memset(pTmp, 0, nDataSize + 1);
//memcpy(pTmp, &m_pData, nDataSize);

Hi.
Thanks to everyone who replied to my last post, it turns out it wasn't
the line where I was trying to treat the variable in question as an
array which was the problem, but the line above.
char temp;
std::vector<unsigned charmmessage;
while (!done){

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
