Win95 version fix

Can someone check the value proposed by Bob Goodwin? Or alternately, how would I check it myself? I have access to Win95/98/2000/Me so I could also check the value for Win2000 and even add one for Wine Me. Btw, if someone needs to check values for one of the above platforms and you can provide me with a simple test program, just let me know. I can probably help you. Of course, the simpler the program is to execute, the more likely I am to be able to help you. I can also accept source (Win32) so you can develop the test program with Winelib and just send me the source, I'll recompile it on Windows. -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ Avoid the Gates of Hell - use Linux.

Well, lack of people writing documentation is a problem in most open source projects and Wine doesn't seem to be an exception. However, denying people the possiblity to do so for some functions doesn't help either. > > I can't fix winapi_check properly.

What kludge? Ugly OK, that is your subjective opinion, but kludge? Even if we only see it from a purely C language perspective, it solves the problem of making sure that the C library functions have the prototypes we expect them to have. There is no other way to solve that problem that I can think of so it is certainly not a kludge. Of course you can always argue that it is a solution searching for a problem, but that is not a what I would call a kludge. Anyway, arguing about misuse of words is a waste of time and I don't think I have anything more to add that are likely to convince you. If you are not convinced now, you never will be.

However note that I'm not suggesting that we shuld. I said "While we probably should not actually change the .c files to look like this until we have a tool of acceptable complexity that can generate the .spec files, there is quite a few preparations that need to be done before that" But OK, I will concentrate on supporting normal entry points in an acceptable way first. > > While we probably should not actually change the .c files to > > look like this until we have a tool of acceptable complexity > > that can generate the .spec files, there is quite a few preparations > > that need to be done before that and I would really like to have the > > "Exported external functions" patch applied in the meantime > > for other reasons like winapi_check likes to know where all > > the DLL:s functions are "implemented". > > Then fix winapi_check.

First of all ugly is subjective, I can't see what is ugly about it, but OK you decide what you want, so arguing that point is no use. However I'm a little curious where the documentation, and yes I'm talking about real documentation not just the external name and the ordinal, should be placed. Sure you have the underlying Unix man pages at least if we are talking about the MSVCRT and NTDLL functions, but it would be nice to have a proper Windows style man page for them eventually. Perhaps the some of the functions have some limitation in Windows that the Unix variant doesn't have (or vice versa) and thus if you extend the Winelib application you really want to know that, so the Unix man page will not really be enough. So yes, I'm really curious to know where you think the documentation should be placed. I think my solution is quite good since it solve three problem. 1. Provides somewhere to write the documentation 2. Provides a C compiler checkable prototype that can give a warning if any of the native system functions happends to have another prototype. 3. Helps tools like winapi_check a place to check things that the .spec files entries are correct. Even if you still considers it ugly, it might be worth it considering what you get. > So no, I'm not > going to apply your patch. I can't fix winapi_check properly. I can kludge it yes, but fix no. There is no implementation or anything else in the source that indicates that it is supposed to use functions from another DLL. But sure I can kludge winapi_check to ignore the atom functions and lstrcmpi in USER. The functions from the C Library is already kludged since a long time ago, so what the hell lets just add another kludge, it is only 5 new functions. If you don't apply it I don't have much choice have I.

Sure we can, that's the easy part; the hard part is making it work for the normal entry points. And I'm not going to add anything to support stubs etc. until it's clear that we can do it for normal entry points in a way that I consider acceptable. > While we probably should not actually change the .c files to > look like this until we have a tool of acceptable complexity > that can generate the .spec files, there is quite a few preparations > that need to be done before that and I would really like to have the > "Exported external functions" patch applied in the meantime > for other reasons like winapi_check likes to know where all > the DLL:s functions are "implemented". Then fix winapi_check. I don't want to have to add a bunch of external declaration for C library functions, that's very ugly.

Re: hello all
by Travis Michielsen July 14, 2001

July 14, 2001

Hi all, After reading Brandon's message I was inspired to introduce myself to this list as well. Although I have been following wine for several months now, I have just recently started wine development (only 1 small patch so far :-( ). Currently I am focusing on learning the API before I persue patches that are significantly larger, but have started a todo list. I am an avid C/C++ programmer and have experimented with serveral other languages including Java(script), Pascal, Basic, etc. I have done allot of programming for Windows/DOS in the past but when I discovered linux about 2 years ago, I immediately switched OS's and began pursuing linux programming. I do, however, still run windows occasionally, when I have trouble running programs under wine, but I believe that someday (hopefully sooner rather than latter), we will be able to use linux (and wine) to run almost every program without thought. Anyways, Welcome Brandon, and Hello All. :) Travis Michielsen __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!

[PATCH] Toolbar : image list can be changed after TB_SETIMAGELIST;
by Gerard Patel July 14, 2001

July 14, 2001

The imagelist of a toolbar can be changed by the app after it has set it to the toolbar (using TB_SETIMAGELIST). In this case the bitmap number can be wrong, leading to some apps not displaying text correctly (although the bitmaps were still showing because of Wine code not really testing for bitmap number in this case). Fix for Winzip 8.0, replaces the preceding one (same problem) ChangeLog: * dlls/comctl32/toolbar.c Refresh bitmap count to take in account imagelist changes after TB_SETIMAGELIST

But if it requires a Perl > script as complex as winapi_check, especially the maintaining of the > *.api files, I'm not sure it's a win. Well the *.api files (or at least the manual maintainance of them) will be eliminated some day. I will just have to implement parsing of the "typedefs" in the headers. However, note that I'm not suggesting that we change to automatic generation of spec files right now, but at some point in the future. What tool we should for it is a later problem. With the exception of which types maps to which "kinds" (long ptr str wstr) the tool will not nessarily be very complex and I'm not sure what the parsing of typedefs to find out will be very complex either. But I wont know until I try. What primarily intrests me now is how should the needed information be stored? The problem with normal entry point is solved, the question is how the stubs and forwards should be stored? Before we know that we can't really write any working extraction tool can we? While I'm not entirely happy with your: /* ##spec## foo "@ forward bar(ptr str) BAZ.bar" */ solution it is the better that any ideas I have. Simplicity has its charm. :-) Then we could just, taking USER as example add /* ##spec## user "name user" */ /* ##spec## user "type win16" */ /* ##spec## user "heap 65520" */ /* ##spec## user "file user.exe" */ /* ##spec## user "owner user32" */ /* ##spec## user "rsrc resources/version16.res" */ /* ##spec## user "2 stub OldExitWindows" */ /* ##spec## user "3 stub EnableOEMLayer" */ /* ##spec## user "4 stub DisableOEMLayer" */ /* ... */ in a appropriate place in say dlls/user/user_main.c. The order that winapi_extract finds the directive is not important the .spec file format happends to make it possible to always get everything in the right order anyway. However this solves the header, the debug_channels, forwards and stubs problem and could be used to solve the remaining problems with "Exported external functions" but I would rather have it solved with my patch with that name, that you didn't apply when applying the other patches. So will accept such a solution? While we probably should not actually change the .c files to look like this until we have a tool of acceptable complexity that can generate the .spec files, there is quite a few preparations that need to be done before that and I would really like to have the "Exported external functions" patch applied in the meantime for other reasons like winapi_check likes to know where all the DLL:s functions are "implemented". > And it seems to me you are > finding a lot more errors in the comments than in the spec files ;-) Well, considering that our developers have neglected the comments for many year and only changing the spec files that is not very suprising. That is the problem with having redundant information, most developers only change where it really count either out of ignorance or lack of time. > > In addition it will be much easier for the developers (especially > > newbies).

The spec entry is dictated by > the dll interface, and there is no reason to change it (except maybe > to change a 'ptr' into an 'str', but this is a cosmetic issue). Well, you also have implementing new functions. You have FooA and want to implement FooW for example. It is much easier and much more natural to be able to just cut and paste without having to change the spec files. I have seen many such errors detected by winapi_check over the years.
