Re: mixing SHELL32.DLL and SHFOLDER.DLL

Moreover, my > shell32.dll doesn't export SHGetSpecialFolderPath* > by a name, also. Hm. I'm sorry, I wasn't clear enough. From MSDN on SHGetFolderPath: This function is a superset of SHGetSpecialFolderPath, included with earlier versions of the Shell. On systems preceeding those including Shell32.dll version 5.0 (Windows Millennium Edition (Windows Me) and Windows 2000), SHGetFolderPath was obtained through SHFolder.dll, distributed with Microsoft Internet Explorer 4.0 and later versions. SHFolder.dll always calls the current platform's version of this function. If that fails, it will try to simulate the appropriate behavior. So, I think your patch is a good first step, to use GetProcAddress rather than letting the linker do it. A next step would be, I think, to do what I suggested: if this fails, try to GetProcAddress for SHGetSpecialFolderPath, since this was available on older versions of shell32. You might have to search by ordinal if searching by name fails. So, I don't think my suggestion is that different from Juergen's, just that I suggest an implementation of "try to simulate the appropriate behavior" if the function is not in fact in shell32. --Juan _______________________________ Do you Yahoo!?

I'm trying to fight spam like anybody else, and first thing is to remove mail adresses from every page on the internet. A google search on my adress shows only 2 pages where i compare, they both come frome wine archive: http://www.winehq.com/hypermail/wine-devel/2003.04.txt http://www.spinics.net/lists/wine/msg08863.html Is there a way to make them remove from there? Just a suggestion: i'm conscious that mail adress need to be post into such a mailing list, but wouldn't be good to keep a script running that alter them into something like 'myname {at} mydomain' ? Just a little sacrifice for everybody to help fighting spam. Think about.. pls... -- Davide Giannotti ITS Planet s.n.c davide.giannotti {at} itsplanet.com www.itsplanet.com

That's wrong; if the libc function exists you should use it, direct system calls should only be used as a fallback. And when using system calls you must not depend on the libc header, you have to define the structures yourself. -- Alexandre Julliard julliard(a)winehq.org

Debug Channels trashed

Hallo, I am trying to run the WebPACK_42wp30_full_installer.exe : http://direct.xilinx.com/direct/webpack/42wp3/\ : WebPACK_42wp30_full_installer.exe (a 110 MByte Download).

Linux registry
by Robert van Herk 31 Aug '04

31 Aug '04

Not knowing how much off topic this would be, I just thought I paste a link here: http://registry.sourceforge.net/ These people seem to be implementing a kinda Windows registry clone into Linux, but then secure, stable 'n' stuff... Since the many registry implementation discussions here, I thought, why not throw this into the discussion too? It might be worth to take a look here and perhaps think about using some of their stuff. Greetings, Robert van Herk

The WM_USER+2 thing is something a specific caller was doing, it's not part of the function itself. I think the shell32 functions should simply forward to the shlwapi ones. -- Alexandre Julliard julliard(a)winehq.org

What are you trying to accomplish? For example, it seems reasonable to assert that you must use the builtin shell32 and shfolder.dll in combination, or not at all, as Alexandre once suggested. Or, in order for Wine's shfolder.dll to succeed on older (native) versions of shell32.dll, it seems reasonable to have it call SHGetSpecialFolderPath* from SHGetFolderPath*, as MS' version does. In other words, why do you need the combination of native shell32 and builtin shfolder.dll? --Juan __________________________________ Do you Yahoo!? New and Improved Yahoo!
