How to convert an int to a const wchar _ t?
As the title indicates I want to know the best way to convert an int to a const wchar_t* . in fact I want to use the _tcscpy function Since you are using a C approach (I’m assuming that m_reportFileName is a raw C wchar_t array), you may want to consider just swprintf_s () directly:
Is there such a thing as a wsprintf?
wsprintf () is one of Microsoft’s hybrid functions. It has a different signature depending on whether or not _UNICODE is defined during preprocessing. (What’s happening under the hood, is there’s an #ifdef that replaces wsprintf with wsprintfA or wsprintfW based on the nonexistence or existence of that symbol.)
How to convert an int to a string?
That’s not a “conversion”. It’s a two-step process: Format the number into a string, using wide characters. Use the address of the string in the call. The first thing can be accomplished using e.g. StringCbPrintf (), assuming you’re building with wide characters enabled.
How does swprintf and sprintf function work?
sprintf returns the number of bytes stored in buffer, not counting the terminating null character. swprintf returns the number of wide characters stored in buffer, not counting the terminating null wide character. The sprintf function formats and stores a series of characters and values in buffer.
How to convert wchar _ t to string in C + +?
In a more modern C++ approach, you may consider using std::wstring instead of the raw wchar_t array and std::to_wstring for the conversion. That’s not a “conversion”. It’s a two-step process: Format the number into a string, using wide characters. Use the address of the string in the call.
How to convert an int to lpcwstr in wsprintf?
I really newbie in using wsprintf. Any one can help me explain clearly for me using this function??? (Please, I also read MSDN but still dont’t clear) You initialize your buffer to nullptr. Just create an array of wchar_t s that allocates enough space for you and you’re off the hook: Thanks for contributing an answer to Stack Overflow!
How to convert unsigned int to’tchar’?
Then convert s.c_str () to a TCHAR*. Also you should take a look to MultiByteToWideChar. The usual way is to use swprintf to print wide characters into a wchar_t (which TCHAR is normally defined as).
