C/C++ : converting std::string to const char* I get the error : left of '.c_str' must have class/struct/union type is 'char *' C# to C++ dll - how to pass strings as In/Out parameters to unmanaged functions that expect a string (LPSTR) as a function parameter. C++ int to str...
You can convert the System::String to a std::string via: // Requires: #include <msclr/marshal_cppstd.h> auto str = msclr::interop::marshal_as<std::string>(txtBoxPath->Text); Once you have a std::string, then c_str() will provide you the const char*: const char* cPath = s...
Thank you! When you usegroup0in the initializer list ofdecay to pointer to first element. This means that for expressiongroup0, the type will be of&group0[0], which ischar**
You need the CHAR pointer from CString, that can be assigned to CString, Code Block CString xyz = "Name"; String strX(xyz.operator LPCSTR()); Wednesday, October 24, 2007 11:55 AM From CString to std:: string, you mean CString cs = "..."; std:: string s = (LPCSTR)xyz; Alterna...
C# will not let me use a pointer and the code it not with with out one C# - change windows color scheme C# - How do you send message from server to clients C# - 'Using' & 'SQLConn', Does the connection close itself when falling out of scope? C# - Access to private method from...
This example demonstrates how to convert from a char * to the string types listed above. A char * string (also known as a C-style string) uses a terminating null to indicate the end of the string. C-style strings usually require 1 byte per character, but can also use 2 bytes. In ...

This post will discuss how to convert a std::string to const char* in C++. The returned pointer should point to a char array containing the same sequence of characters as present in the string object and an additional null terminator at the end.
