If you want to use VirtualAlloc to set aside memory and retrieve it by pages, your first call should only do a MEM_RESERVE on the maximum size of memory you plan to use. Then when you need more, you will make another call using MEM_COMMIT to get access to the page....
You can use the Resource Acquisition Is Initialization (RAII) pattern to limit oversubscription to a given scope. Under the RAII pattern, a data structure is allocated on the stack. That data structure initializes or acquires a resource when it is created and destroys or releases that resource ...
CStringA cstringa(orig.GetBSTR()); cstringa += " (CStringA)"; cout << cstringa << endl; // Convert a _bstr_t to a CStringW string. CStringW cstring(orig.GetBSTR()); cstring += " (CStringW)"; // To display a cstring correctly, use wcout and // "cast" the cstring to (...
<CODE>ReleaseBuffer()</CODE>, you must not use <CODE>pch</CODE> any more, again because the <CODE>CString</CODE> may reallocate and move the character array.</P> <P>If you want to create a larger buffer for the string, for example if you are ...

It takes two parameters – First, the character array to which we want to convert and the size of the string. The below program will help you understand it. #include <iostream> #include <cstring> using namespace std; void print_char_array(char array[], int size) { for(int i=0; i...
To use CString without copying while sending. Use function void send(int code, const String& contentType, const char *content, bool nonDetructiveSend = true); // RSMODsuch asrequest->send(200, textPlainStr, cStr, false);The required additional HEAP is about 1 times of the CString size...
