Unicode to string and back

[Andy]

Well,

I've tried for hours now and getting nowhere on this.

This is the unicode conversion program by Fasecero (slightly modified and much appreciated):

What I'm trying to do is to take the WSTRING and convert it back to unicode characters and place them in EDIT_9.

Help please!

Andy.

It's okay, I've found it!

I was using SETCONTROLTEXT instead of SetWindowTextW:

SUB DoWork(wstring base)
   buffer = W2S(base)
   SetWindowTextW(GetDlgItem(d1.hwnd, EDIT_9),base)
ENDSUB
