Re:CryptoAPI
by Eric Pouech 18 Aug '01

18 Aug '01

from a pure technical point of view, the crypto API is in a pure WOSA style : - a set of high level API (in advapi) - an extendable set of low level service providers (here for example the crypto algos - RSA....) - the high level maps the fonctional request of the user onto on of the available SP. so, my advice here would be to implement this type of scheme. This would allow to: - use native DLLs if they exist (and go beyond what's supported by Linux) - still allow to use Linux lib (just build a wrapper DLL to that lib) and you should be all set from a copyright point of view: - Wine use a X11 like licence, so make sure all the external libs you use are not GPL (LGPL is fine). If they are GPL, you won't be able to ship the result with Wine. - Use of native DLL is granted as long as you have a Windows licence on the target machine (native DLLs shall not be shipped with Wine, Wine should be configured to use the local resources) from an exportation point of view: - some countries (US as an example) puts lots of contraints on the type of crypto algo to be used outside of the US. So those shouldn't be shipped with Wine's, but be provided as an external resource) > Hi, > > I was going to start implementing the Cypto API (in advapi32.dll) over the > next few weeks.

dsound ??
by Bobby Bingham 17 Aug '01

17 Aug '01

Hello all, I completely rebuilt my computer a while back, and updated wine, so I'm not sure which is causing it, but not dsound doesn't seem to work where it did before. Starcraft doesn't play any music, sound, etc, but it's installer still plays it's sound (without dsound). Before this I hadn't updated WINE for a while, so I'm not sure when it broke. Bobby Bingham

The >non-client area should be painted upon WM_NCPAINT, not WM_ERASEBKGND. How do you test this under Windows ? In my test app, I have a white brush as class brush. So my window is white. If I add after the BeginPaint : GetClientRect(hwnd, &r); r.top += 200; FillRect(ps.hdc, &r, (HBRUSH) COLOR_WINDOW) the lower part of my window is painted with the beautiful window color (brown) Now if I add immediately after : hdc = GetWindowDC(hwnd); SendMessage(hwnd, WM_ERASEBKGND, (WPARAM) hdc, 0); ReleaseDC(hwnd, hdc); I get a window that is completely white; maybe I am missing something but I should see a small brown strip at the lower part of the window, corresponding to the caption + menu height, no ?

Yes; actually I realize now that my test app uses the CS_PARENTDC style, which is why I see that. The behavior that you observe is what happens without CS_PARENTDC; so it's actually more complex that I thought, we'll need to explicitly test the CS_PARENTDC flag.

Re: Problems building with extern inline functions in winebase.h

That's not what Windows does. If you pass a window DC to WM_ERASEBKGND it only erases an area equivalent to the client area (shifted to be relative to the whole window), so GetClientRect is correct IMO. The non-client area should be painted upon WM_NCPAINT, not WM_ERASEBKGND. -- Alexandre Julliard julliard(a)winehq.com
