问题 I'm trying to convert from string to LPCWSTR (I use multi-bite). 1) For example: LPCWSTR ToLPCWSTR(string text) { LPCWSTR sw = (LPCWSTR)text.c_str(); return sw; } 2) This returns Chinese characters: LPCWSTR ToLPCWSTR(string text) { std::wstring stemp = std::wstring(text.begin(), text.end()); LPCWSTR sw = (LPCWSTR)stemp.c_str(); return sw; } However, they both always shows squares: Image EDITED: My code with an edit by: Barmak Shemirani std::wstring get_utf16(const std::string &str, int

Cannot convert parameter 2 from 'const char [14]' to 'LPCWSTR'

问题 I am getting this error: cannot convert parameter 2 from 'const char [14]' to 'LPCWSTR' With the code below. It is supposed to be C but at best visual studio 2012 offers an empty c++ project: #include "windows.h" int WINAPI WinMain (HINSTANCE hinst, HINSTANCE hprevinst, LPSTR cmdline, int showcmd) { MessageBox(NULL, "Merhaba Dunya", "Merhaba", MB_OK); return 0; } What is incorrect? 回答1: It seems your current settings are set up so that WinAPI functions expect wide strings: MessageBox(NULL, L

store a variable that holds user input data in sapi5 speak function

问题 I am developing an application that uses the Microsoft SAPI5 speech engine. However, I have hit a wall. I've been trying to use the data from the variable that stores the input from the user so the TTS engine can repeat it. But the sapi5 speech function does not allow strings, wstrings or other types except from LPCWSTR which from my research is a pointer to a wide character string, so shouldn't it accept wstrings? Here's some example code from msdn : #include <stdafx.h> #include <sapi.h> int

问题 I ahve the following piece of code. I get a correctly filled vector. But I am unable to print or use the vector contents which are file names from a directory. As soon as I do enter the first iteration. Everything gets lost.

Cast (const) char * to LPCWSTR [duplicate]

问题 This question already has answers here : How do I convert a char string to a wchar_t string? (4 answers) Closed 5 years ago . I'm trying to use FindWindow() from WinAPI, and I want to ask an input for window's title from the user: char *input; cout << "Window title: "; cin >> input; Pretty standard. Now then, how do I convert this to LPCWSTR for FindWindow() ? I've already tried the following: _T(input) , TEXT(input) , (LPCWSTR)input but none of them worked. I also tried using wchar_t instead
