I think you can reuse heap_strdupW() from propsheet.c for that, first moving it to a header, and changing Alloc() -> heap_alloc(). No need to null check before releasing old text by the way.

Could you use lstrcpynW() for this? Also it seems inaccurate for null text case - for ES_MULTILINE it shouldn't touch output buffer, and for single line case it write empty string, that's according to my quick testing, we'll need some tests for that.

Move this up please. You can test that returned buffer is not null terminated as indication of unimplemented message on XP. No reason to run other tests before this skip if it's not going to work.

I'm not sure I understand. For "null text case" this will always return FALSE. If the control has ES_MULTILINE, then es->cue_banner_text will be null, so it won't touch output buffer. I included tests to Set/Get the empty string. It shouldn't crash; I'll fix that.

I think you can reuse heap_strdupW() from propsheet.c for that, first moving it to a header, and changing Alloc() -> heap_alloc(). No need to null check before releasing old text by the way.
Ok.

Could you use lstrcpynW() for this? Also it seems inaccurate for null text case - for ES_MULTILINE it shouldn't touch output buffer, and for single line case it write empty string, that's according to my quick testing, we'll need some tests for that. Also is it supposed to crash on null destination?
I'm not sure I understand. For "null text case" this will always return FALSE. If the control has ES_MULTILINE, then es->cue_banner_text will be null, so it won't touch output buffer. I included tests to Set/Get the empty string.
I mean buff != NULL && size != 0 && cue_banner_text == NULL, what happens to buff.
Your are right; it is writing empty string in the case you are considering. I'll update tests for this case.
It shouldn't crash; I'll fix that.

Move this up please. You can test that returned buffer is not null terminated as indication of unimplemented message on XP. No reason to run other tests before this skip if it's not going to work.
Ok.

Now looking again, it seems it would be better to move this to WM_PAINT, because it does not have to be called for every line. Does this complicate (x,y) calculation a lot?
I'll look into this. Hopefully retrieving (x,y) won't be complicated.
However, since CUE BANNER only makes sense for single-line controls, it'd be called only once (when painting the one and only line). For multi-lines it will never be called. Could we just take advantage of already having (x,y) and leave the code where it is?
