How do I turn a char pointer into a string?

When you say char * str1 in C, you are allocating a pointer in the memory. When you write str1 = “Hello”; , you are creating a string literal in memory and making the pointer point to it. When you create another string literal “new string” and assign it to str1 , all you are doing is changing where the pointer points.

How do you convert char to Lpwstr?

“c++ convert const char* to LPCWSTR” Code Answer

1. const char *p = “D:\\”;
2. const WCHAR *pwcsName; //LPCWSTR.
3. // required size.
4. int size = MultiByteToWideChar(CP_ACP, 0, p, -1, NULL, 0);
5. // allocate it.
6. pwcsName = new WCHAR[nChars];
7. MultiByteToWideChar(CP_ACP, 0, p, -1, (LPWSTR)pwcsName, size);
8. // use it….

How do I convert to Wstring?

C++ Convert string (or char*) to wstring (or wchar_t*) string s = “おはよう”; wstring ws = FUNCTION(s, ws);

Can a pointer be a char?

The type of both the variables is a pointer to char or (char*) , so you can pass either of them to a function whose formal argument accepts an array of characters or a character pointer.

Can char * point to a string?

The char* indeed points only to the first character of your string, however functions like printf(“\%s”) will simply start reading and continue until they find a 0-byte. String literals like your “Stack” example are zero-terminated by default, thus printf will know to print your string and stop after that.

How do you convert CString to Lpwstr?

If you specifically need Unicode, you can use CStringW, even in a non-Unicode program. LPSTR psz = (LPSTR)(LPCSTR)str; The (LPCSTR) cast actually calls a conversion operator on CString, which returns a pointer to the CString internal buffer. The (LPSTR) cast removes the const-ness of the pointer.

How do you convert Lpcwstr to Lpwstr?

Just create a new array of wchar_t and copy the contents of the LPCWSTR to it and use it in the function taking a LPWSTR. You probably need to create a copy of the string, and pass a pointer to the copy. An LPCWSTR i a pointer to a const , which means the content can’t be modified.

How do I convert Wstring to CString?

The easiest solution is to use Unicode string literals and std::wstring: wstring z = L”nüşabə”; CString cs(z. c_str()); nameData. SetWindowTextW(cs);

How do you convert Wstring to Lpcwstr?

4 Answers. Simply use the c_str function of std::w/string . If LPCTSTR is const char* then there’s no reason you should be using std::wstring . Conversely, if you think you should be using std::wstring , set the UNICODE flag in your project options.

How to cast ANSI Char to wchar_t?

What is wchar_t under MS-Windows?

Also wchar_t under MS-Windows uses UTF-16 which adds another fun thing to take in account when measuring the string length. – Alexis Wilke Oct 20 ’14 at 1:28 Add a comment | 7 Answers 7 ActiveOldestVotes 42 In your example, wcis a local variable which will be deallocated when the function call ends.

What is WC in C++?

In your example, wc is a local variable which will be deallocated when the function call ends. This puts you into undefined behavior territory. The simple fix is this: const wchar_t *GetWC (const char *c) { const size_t cSize = strlen (c)+1; wchar_t* wc = new wchar_t [cSize]; mbstowcs (wc, c, cSize); return wc; }

How to convert string to wide character set in Windows SDK?
