What is a Lpwstr?

The LPWSTR type is a 32-bit pointer to a string of 16-bit Unicode characters, which MAY be null-terminated. The LPWSTR type specifies a pointer to a sequence of Unicode characters, which MAY be terminated by a null character (usually referred to as “null-terminated Unicode”).

What is Lpctstr type?

LPCTSTR is a pointer to a const TCHAR string, ( TCHAR being either a wide char or char depending on whether UNICODE is defined in your project) LPTSTR is a pointer to a (non-const) TCHAR string.

What is Lpstr in C?

LPSTR stands for “long pointer to string”. Back before 32-bit processors, pointers to memory that might be in a different segment of memory (think, a long way away in memory), needed extra space to store. On 32-bit (and later) processors, they’re exactly the same thing. Microsoft uses LPSTR solely for historic reasons.

What is Lpcwstr C++?

LPCWSTR stands for “Long Pointer to Constant Wide String”. The W stands for Wide and means that the string is stored in a 2 byte character vs. the normal char . Common for any C/C++ code that has to deal with non-ASCII only strings.=

Is CString same as string?

Well, is basically a header containing a set of functions for dealing with C-style strings (char*). , on the other hand, is header that allows you to use C++-style strings (std::string), which can do a lot of if not all of the functions provided in on their own.

How do I use Tchar data type in MAPI?

MAPI clients can use the TCHAR data type to represent a string of either the WCHAR or char type. Be sure to define the symbolic constant UNICODE and limit the platform when it is required. MAPI will interpret the platform information and internally translate TCHAR to the appropriate string.
