Lets say I have a char pointer and an std::string. Is it possible to get a
pointer to the std::string's "content" so that the char pointer can point to
the same text? And vice versa; can I give the std::string a pointer and a
length and then give the std::string control over the pointer and its
content?
I'm basically trying to avoid copying large text between an std::string and
a char pointer, and vice versa.
Is there anyhing in the...

All,
If I am not mistaken I had some problems with code like this:
std::string foo, bar;
....
somefunc( foo.c_str(), bar.c_str() );
Problem was that c_str() used buffer shared btw instances of
std::string in that implementation. I did not find anything that

Does this function need to call eof after the while-loop to be correct?

Following code works fine, when compiled with VS 6.0, but not anymore when compiled in .NET. What's wrong here, I can't see it by myself?
arrString content will be garbage with .net compilation, but when compiled with 6.0 it contains string from Vector (that's how I want it to work).
std::vector<std::string> Vector;
...
void MyClass::DoThis(std::vector<std::string> Vector)
{
const char *arrString;

I need to make a class called uid.
A UID is a unique identifier.
It looks like... 1.2.3.345.1.2.4.566
This uid get transmitted over a network as 8 bit binary data.
If the length of the UID is odd, an extra padding null \0 is added
to the end.
This is what I've written but I'm not sure if I've garanteed to have
the c_str() method return a buffer that is null padded.

Im very much a newbie but perhaps somehone can help me. Ive been
searching for a way to convert a std::string to a unsigned char*
The situation is I have a function that wants a unsigned char* and I
want to give it a std::string
no matching function for call to `MD5::update(std::string&, size_t)'
candidates are: void MD5::update(unsigned char*, unsigned int)
void PrintMD5(string str){

hi,
i need that because the path functions for windows, like PathAppend
and PathRemoveFileExt accept a writable zero terminated char*, but i
didn't find that for std::string, with CString, i usually use
GetBuffer for that
LPTSTR CString::GetBuffer( int nMinBufLength )

Overview:
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,...

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....

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
