I need help with std::wstring

Post by AlexM »

Hi,
I'm trying to build a plugin for Rainmeter and I'm stuck.
I have a function called ephemeride(), which return a std::wstring.
What I want to do with this wstring is to print it on my skin but when I "fetch" the wstring and put it in the value member of my Measure struct, all I get on the skin is three random characters. They sometimes changes when the skin updates.
I checked the values in rainmeter's log, the wstring from ephemeride() is ok since it has the correct length, but when I check the content, it's only 3 characters (as shown on my skin)
I attached three screenshots, the skin on my desktop, the log from rainmeter and the code of my plugin
Thanks for your help, I really need it ^^

The RmLogF functions basically wrap around the printf function. The %s specifier wants a "C string", so you have use the raw C-style string instead of std::wstring.

So, try text.c_str() instead of just text in the _snwprintf_s and RmLogF function calls.
