newbie question
by Preetham 10 Jul '02

10 Jul '02

Hi all: I have a very elementary question. How does the Winodws program run in Unix. For example, i write a program where i call the CreateBitmap() method, what happens. How is a dll called in the unix environment. From what i know, unix dlls are .so files. From the wingdi.h file in the wine\include directory, how does the unix OS know how to resolve the WINAPI call. If i am right, windows dll's are implemented in unix, how is this done. I'm kinda flustered at the moment, would appreciate the help Thanks, Preetham.

Known issue. The debugger doesn't yet know how to handle the extended information available about C++ classes. (If it really cheeses you I have a patch that basically replaces the detailed garbage with "we don't understand") Bill

Converting resources from A to W and vica versa
by Shachar Shemesh 09 Jul '02

09 Jul '02

Hi list, Returning after a short absence, I have bug 864 to discuss (I have opened it, and will soon be closing it). The problem was that a program I wrote used "ChooseFont" with a resource. I know those are not supported, but when compiled for Unicode (in VC), the program crashed when trying to open the dialog. Investigation revealed that a function called "ChooseFontWtoA" is called, and that, in turn, assumes that lpTemplateName argument is a string. In practice, this argument was actually an int after being handled with "MAKEINTRESOURCE". I will shortly be sending a fix to wine-patches, but I just wanted to draw your attention to the fact that when handling resources, they are not necessarily strings. Failure to recognize this will crash programs. Worst, and this is not the first place I have seen this, this argument is accessed and handled even if the "CF_ENABLETEMPLATE" flag is not set. In other words, an argument that the MSDN promises will not be touched unless a flag is set can crash a program if not set correctly, even if the relevant flag is not set. In short - pay attention, people. Even when implementing stubs, do read through the arguments list and meanings. Shachar

'Runtime Error 429', and $ offered for a fix
by Sean Russell 09 Jul '02

09 Jul '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I originally posted this to c.e.ms-windows.wine, but I wanted to cross post it to the developers list in the hopes of attracting the proper attention. I appologise if it is inappropriate to offer money for solutions, in this list. My wife is an author. For the past eight months, she's been happily working exclusively on Linux with OpenOffice. She just recently accepted a job doing some tech writing; the application she is to document is a Windows application, made (apparently) predominantly of VB. This application fails to run under a recent Wine. I'm considering two options: (a) Buy a copy of Windows and VMWare, and (b) donate the money I'd spend to a Wine Guru or the Wine project instead, to get the application running. I'd MUCH rather give my money to the Wine project, but this is only an option if I can reasonably hope for a quick turn-around. I'm trying desperately from having to give money to Redmond and incidentally having to maintain a Windows install on her computer :-( Windows would cost me $100, $150 with VMWare. I'll happily donate that to the Wine project, or a Wine developer. It isn't a lot, I know, but if anybody is willing to take this on, please let me know. If it looks like a simple fix, then fine. If it looks like a lot of work, then just let me know and I'll grab a copy of VMWare. I don't have the sourcecode for the application. If you're interested in taking a look at this, email me at 'ser at germane dash software dot com', and I'll send you console dumps, Wine versions, etc. The basic error that the Windows dialog gives us is: Runtime Error '429' ActiveX component can't create object Thanks, sincerely.

MS' hidden API
by Zhang Shu 09 Jul '02

09 Jul '02

Dear wine developers, I have one question on the development of wine. Long(one or two years) ago I've heard that Microsoft got some hidden APIs in their products of various windows, and they use these APIs in their own applications. I wonder if this is still a problem on their recent product like windows XP. If it is, I guess wine will not be able to run such MS applications which uses hidden APIs. Is this right? And, is wine designed(or its goal is) to run all applications(including MS product and non-MS product) that runs on windows? Please forgive me if this problem has appeared in the past. I just joined this list a couple of days ago. Thank you. Regards, -- Zhang Shu

One more try at bug 829 (same surface corruption)

malloc, heapalloc, etc
by John Lightsey 08 Jul '02

08 Jul '02

Hi all, I've been playing around with the wininet dll to get a windows app I developed running, and I've written a patch that fixes the problems with wininet that I've noticed, but it's an ugly fix and I'd like to get a little clarification about how heap memory is being used in Wine. In dlls/wininet/internet.c InternetOpenUrlA() malloc() is used to put together the HTTP host header in hostreq. The pointer is then passed to HttpAddRequestHeadersA() which creates a buffer with HeapAlloc, copies the contents pointed to by hostreq to it then frees the buffer with HeapFree. Control then passes back to InternetOpenUrlA which does not call free() on the hostreq pointer. So, my question is which is the encouraged way of doing things? HeapAlloc and HeapFree or malloc and free? Also, is the fact that free() was not called on hostreq a bug, or am I missing something? Please be gentle....I'm a Perl programmer, not a C programmer.

about programming books
by Andreas Mohr 08 Jul '02

08 Jul '02

Hi all, I just created http://wine.codeweavers.com/fom-meta/cache/831.html to list all the Windows programming books I own (16 books ! ;-) I'd be happy if some other people could add an entry, too. That way we'd have an amazing information resource whenever needed. Hmm, I just hope you've got editing capabilities on this page. If you're unable to add something, then please tell me. (or just edit an entry in some FOM category where you're able to edit it, I'll move it there then) Of course I will add more details of the books to the page once I feel bored (actually a separate page per book within a sub category per author would probably be better). Thanks ! -- Microsoft Licensing 6.0: "Pay us now in advance, so that we can own you later."
