I believe Alexandre plans to have Wine configured via the registry eventually. Then it would probably make sense to have a C program that acted as a control panel applet and did what WineSetupTk does, but in a dynamic fashion using the registry APIs. Until then I would expect a C version of WineSetupTk to be rather ugly from having to deal with much text config parsing and manipulation.

It is the same that when you are doing a videogame console emulator. You don't start testing the comercial games first, you start with simple demos, when you will get the basic working, then start with more complex one, and so. The important is not run this applications, the important is that sure that the authors of this applications have used features what are the base of other more complex. So if this features are working correctly, it will be easier run more complex software in the future :) Regards, Carlos. -- ___ _ \ | / Infraestructuras | . |._ _ _| | ___ ___ ___ http://www.andago.com | || ' |/ . |<_> |/ . |/ . \__ GNU/Linux |_|_||_|_|\___|<___|\_. |\___/ _ \ __|\ \ / Carlos A.

The make good test cases and are good as demo applications too, because people who use Windows may know theses already and the list is obviously not a list put together for that purpose because the apps have been selected by Downloaders at tocows.

Plea to fix winelib COM vtable bug
by Matthew Bloch 02 Nov '02

02 Nov '02

This is a summary of my recent probs with Winelib in the hope that someone who knows the COM stuff can fix them quickly, because hacking through the jungle of include files and definitions is hard work In short, I've built the latest wine cvs with the ICOM_MSVTABLE_COMPAT flag set in include/wine/obj_base.h, so each vtable has two dummy words at the start for g++'s benefit. I then added these statements to the start of my WinMain to cause a segfault: IDirectDraw* dd; DirectDrawCreate(0, &dd, NULL;) and for good measure, wrapped the call to IDirectDraw7_QueryInterface in DDRAW_Create (which is where the segfault occurs) in ddraw/main.c with these two warnings: WARN("about to call IDirectDraw7_QueryInterface vtbl size = %d\n", sizeof(DDCF_Vtbl)); hr = IDirectDraw7_QueryInterface(pDD, iid, lplpDD); WARN("called IDirectDraw7_QueryInterface\n"); and when running the program, the trace clearly shows that the Release entry point is being called instead, and crashing, though the vtable is the expected size (5 entry points, plus 2 dummy dwords): warn:ddraw:DDRAW_Create about to call IDirectDraw7_QueryInterface vtbl size = 28 warn:ddraw:DDRAW_Create offset is 12271064 trace:ddraw:Main_DirectDraw_Release (0x403a7c70)->() decrementing from 1. warn:ddraw:Main_DirectDraw_Release doing final release Looking at the pre-processor output from compiling ddraw/main.c, I can see that IDirectDraw7Vtbl type has the two extra words grafted onto the front, as it should: struct IDirectDraw7Vtbl { long dummyRTTI1; long dummyRTTI2; HRESULT (__attribute__((__stdcall__)) *QueryInterface)(IDirectDraw7* me, const IID* const a, LPVOID* b); ULONG (__attribute__((__stdcall__)) *AddRef)(IDirectDraw7* me); ULONG (__attribute__((__stdcall__)) *Release)(IDirectDraw7* me); ... The problem seems to be that the call is offset not just by two table entries, but four. Somewhere in that jungle of macros, the "vtable base adjustment" of +2 is being applied twice, I'm sure of it. But I'm buggered if I can find out where this is happening; I'm still looking but it's slow progress and I believe it's a winelib bug. Any suggestions on how to fix it would be welcome. cheers, -- Matthew Bloch Bytemark Computer Consulting Limited http://www.bytemark.co.uk/ tel. +44 (0) 8707 455026

And everybody is a critic ;) I really hate duplicating code in any function. I'd rather use a macro which make the function 1. more readable, 2. shorter :) I would potentially rather more it to it's own header file than doing the cut-n-paste thing inside a function... Would it be 50% ok with macro abuse in a seperate header file? Greetings Jaco

PATCH: DirectDraw vtable fixes
by Matthew Bloch 02 Nov '02

02 Nov '02

Found it; a few of the DirectDraw ICOM_VTABLE declarations did not have the ICOM_MSVTABLE_COMPAT_DummyRTTIVALUE macro prefixing their elements. This meant that, well, all sorts of havoc broke loose when wrong functions were called :) I hope this is an uncontentious patch attached. -- Matthew Bloch Bytemark Computer Consulting Limited http://www.bytemark.co.uk/ tel. +44 (0) 8707 455026

For this, we should look into supporting the IWebBrowser interface, via Mozilla. It's been mentioned here before. Actually, there is a LGPL implementation for this in the Mozilla tree, it's just that it's written in C++. One option would be to just install the binaries, and that would be it, but it's not that sexy... -- Dimi.
