These are FORCED, GLOBAL values, as such they are highly evil (since that way the whole version detection mechanism gets disabled and many programs which need other values cannot have their version guessed properly any more). Instead, the default fallback values in the version code should probably be changed to refer to Win98 to make sure we do use Win98 in case we cannot guess any value (if they are not already, but they might still be at Win95). Note that the version code has some straw man default values which are NOT the real defaults if you analyse the code path properly. And if IE setup still doesn't run after having changed the default guesstimate to Win98, tough luck: you'll have to force version Win98 manually (or implement a smarter version detection mechanism that takes some observations and transforms them into a Win98 version value). And we should also indicate in the sample config file that actually setting these will override any and all intelligent(?) version detection mechanisms...

EDIT_WM_Create fix.
by Rein Klazes 21 Oct '03

21 Oct '03

Hi, Sent to wine-devel as well: this might break some odd edit controls that I did not catch. This fixes masked edit controls used by applications created by Power Builder, it fixes bug #807. Power builder depends on the return value of the WM_CREATE message by the EditWndProc to be != 0. Now I spent some time creating EDIT windows, varying parameters (with or without text), varying styles including multilines even tested the edit part of a combobox. In all cases the WM_CREATE message return value turned out to be 1. So at the very least this seems to be the common case, and not zero as in wine's implementation. So I propose to put that in, and if it breaks hope it will be caught. ChangeLog: controls : edit.c A WM_CREATE message sent to an Edit window procedure should return 1. Power Builder masked edit controls depend on it. Rein. -- Rein Klazes rklazes(a)xs4all.nl

MDI windows, MDIClient and mdiclient
by Shachar Shemesh 21 Oct '03

21 Oct '03

Hi all, I am trying to make an application work under wine. The app is probably an MFC app, that defenitely uses MDI. The problem boils down to this - it tries to create an MDI window by doing SendMessageA to a message of type "WM_MDICREATE". Here's the catch - the class it wants to use is in Unicode. This fails for obvious reasons. I'm trying to find my way around the MDI setting, and phrase a regression test. However, I cannot seem to create the exact same circumstances. When looking at the original app using Spy++, I see that the application has a window from the very start of the app (long before it sends WM_MDICREATE), which does not appear to have WS_EX_MDICHILD set, but which has a child window of class "MDIClient". Running the same app in Wine using --debugmsg +win,+class, I can see that it asks to open a window of class "mdiclient". I do not, however, see anywhere that such a class was ever registered! Furthermore - the call succeeds. Can anyone enlighten me? Is this window necessary whenever an MDI is present? If so, what function do I use on the parent window to tell it that it is to be an MDI container? Many thanks, Shachar -- Shachar Shemesh Open Source integration consultant Home page & resume - http://www.shemesh.biz/

Re: Fix comctl32 conformance test

Still the test runs (and > thus run-time links) on Wine. Is this wanted behavior? Yes it is, the functions are converted to ordinal imports by the import library. The existing code works just fine, except when cross-compiling on Mingw because the import libraries are broken there. This should be fixed in Mingw not in Wine. -- Alexandre Julliard julliard(a)winehq.com

suggestion, merge WINE and ReactOS MSVCRT
by Jonathan Wilson 21 Oct '03

21 Oct '03

IMO its a waste for both WINE and ReactOS to have 2 different implementations of MSVCRT.DLL/CRTDLL.DLL Is there any valid reason not to either remove one and have both projects use the other or to merge both and come up with one dll?

Window refresh problem with GroupBox and Tabs
by George Marshall 21 Oct '03

21 Oct '03

Hi I've already submitted this bug to the wine bugzilla but I'm posting it here as well 'cause... oh well you know. Pls. look at the end of the message for .gifs Bug 1689 follows: I've got an application which purpose is to just reproduce the wine bug I'm gonna explain below. There is, basically, a window, a tab control with four tabs, some GroupBoxes and a few editboxes. (Please, see the attached .gif to get an idea). Here we go with the interesting part... If you run the application you'll realize that some editboxes are not drawn at all and some other not correctly drawn (Expecially if you go through the tabs...) Now if you minimize and then raise this window or drag part of it out of the screen and then back in, everything in it is correctly "painted". The pic tabwin_ok.gif shows the application correctly drawn, while in tabwin_bad.gif you'll see the application in its bad behavior (Like described above). Another interesting thing to note is that if you go through the tabs backward( from the last one to the first one ) the window contents is correctly drawn, not if you go from the first tab to the last one. This is always reproducible. This bug is 100% reproducible with Wine 20030813, 20030709, 20030618 (the versions I could work with...) I'm actually trying to fix this by myself (an ugly workaround will do the job as well) but any help to get me to the right direction will be appriciated. You're more than welcome to ask for any debug or strace log. Thanks. http://bugs.winehq.org/attachment.cgi?id=359&action=view http://bugs.winehq.org/attachment.cgi?id=360&action=view

Re: will it?
by Ivan Leo Murray-Smith 20 Oct '03

Wine can't load windows drivers. This may be possible in a very very far future, but it would probably be easier to write native drivers. Probably by the time wine can do such a thing, all hardware vendors will support linux anyway.

import and export tables
by Dave Miller 20 Oct '03

20 Oct '03

A .tar.gz containing HTML tables of imports and exports for windows dlls is now available here: http://24.229.94.2/import_export_tables.tar.gz It is about 1MB but it will decompress to 1000+ html files and 58MB! I have not included empty tables where a dll does not import or export any functions. If you spot a missing windows dll, or a non-windows dll please let me know so I can add/remove as necessary. Of course feature requests are welcome as well. ------------------------------------- So many Right-wing Christians. So few lions.
