"= : left operand must be the l-value"

[Markus]

I have had a look on google but nothing conclusive shows up. Anyway.

I'm wrapping some of the Windows GDI API for the PHP project. In particular, in accepting some user-input and then creating a LOGFONT structure with that data. However, the problems comes when I'm trying to set the data for LOGFONT.lfFaceName. This member is of type WCHAR[32]. The title-error occurs whenever I do something like (simplified):

lfont.lfFaceName = (WCHAR *)TEXT("Test");
 

I'm sure I'm missing something newbie-level here.

If it were char*,
strcpyW(lfont.lfFaceName, TEXT("Test");
there must be strcpy equivalent for WCHAR

There is no such thing as strcpyW.

It's wcscpy.

I expect you want to use the secure version wcscpy_s.

TEXT is a TCHAR macro. A TCHAR is either char or WCHAR depending upon whether your project is built for ASCII or Unicode.

That means that using TEXT on a WCHAR member ain't gonna work it the project is set to ASCII.

And, in fact, there is no WCHAR member of LOGFONT. Instead there is a TCHAR member.

And that means you want to use the TCHAR mapped function for your copy which is believe is _tcscpy. _tcscpy is a macro. It resolves to strcpy for ASCII and _mbscpy for Unicode. There are about 75 macros like this.

When you use TCHAR, there should no char or WCHAR in your program. There should be TCHAR only.
