So the WriteFile() call fails in the end. Wine code: http://source.winehq.org/git/wine.git/blob/0effd926b6475842baefc5379b9dd932… --- snip --- 543 int server_get_unix_fd( HANDLE handle, unsigned int wanted_access, int *unix_fd, 544 int *needs_close, enum server_fd_type *type, unsigned int *options ) 545 { 546 sigset_t sigset; 547 obj_handle_t fd_handle; 548 int ret = 0, fd; 549 unsigned int access = 0; 550 551 *unix_fd = -1; 552 *needs_close = 0; 553 wanted_access &= FILE_READ_DATA | FILE_WRITE_DATA; 554 555 server_enter_uninterrupted_section( &fd_cache_section, &sigset ); 556 557 fd = get_cached_fd( handle, type, &access, options ); 558 if (fd != -1) goto done; ... 580 done: 581 server_leave_uninterrupted_section( &fd_cache_section, &sigset ); 582 if (!ret && ((access & wanted_access) != wanted_access)) 583 { 584 ret = STATUS_ACCESS_DENIED; 585 if (*needs_close) close( fd ); 586 } 587 if (!ret) *unix_fd = fd; 588 return ret; 589 } --- snip --- So what did the application intend by _not_ passing FILE_WRITE_DATA? Fortunately there is a hint hidden in the MSDN entry for CreateFile() that explains it: --- quote --- You can get atomic append on local files by opening a file with FILE_APPEND_DATA access and _without_ FILE_WRITE_DATA access. If you do this then all writes will ignore the the current file pointer and be done at the end-of file. (Actually, I'm not sure if the current file pointer is updated to EOF at each write or not, I haven't tested that behavior.) Eg HANDLE hFile = CreateFile(TEXT("c:\\file.txt"), FILE_APPEND_DATA , FILE_SHARE_WRITE, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0); The append behavior is properly synchronized between multiple writes (with or without multiple handles), where the typical way I've seen this implemented (by seeking to EOF and then writing) has a race condition if multiple threads / processes are appending to the same file. This behavior is documented in Windows Driver Kit / Device and Driver Technologies / Installable File System / Reference / IO Manager Routines / IoCreateFileSpecifyDeviceObject (currently at http://msdn2.microsoft.com/en-us/library/ms795642.aspx) --- quote --- If you fix that, the application no longer crashes and purchased mp3 files are successfully downloaded (already tested). $ du -sh AmazonMP3DownloaderInstall.exe 2.2M AmazonMP3DownloaderInstall.exe $ sha1sum AmazonMP3DownloaderInstall.exe 11b08d68fe11006ed402701a85183565ee8e139e AmazonMP3DownloaderInstall.exe $ wine --version wine-1.5.26-19-g6ed2d9b Regards -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

It was a real PITA to install when I did it using native deps, so I'm very happy with that. Library Loader is supposed to be able to launch and connect to DS when the settings button is pressed. In normal use it opens component packages that you download, adds them to the DS library and puts a symbol at your cursor ready to place on the page. When I was running these programs using native dependencies, it all worked well most of the time, but I couldn't install the latest version (2.49) of Library Loader. I was using 2.47, working ok. I installed both programs in a fresh 32bit prefix. Library Loader installed the newest version (2.49) - woo hoo! BUT I am getting an error from Library Loader when I download a new component or when I click the settings button "Unable to launch/connect to Design Spark PCB". Reverting all the way back to v2.28 and it works, much older that what I was using previously. It looks as though mono isn't doing something that it wants. I have set: WINEDEBUG=mscoree WINE_MONO_TRACE=x as per the forum post. The log is from Library Loader 2.49, the newest version which installs with mono but not with .net, but can't find DesignSpark. I launched the program and pressed the "ECAD tool" (DesignSpark selected from list) settings button. The point where the button is pressed is just after the cryptography stuff, where it says "EXCEPTION handling: System.NotImplementedException: The method or operation is not implemented." though this error is also present in the working version, 2.28. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=36815 Bug ID: 36815 Summary: XFORM matrix rotation is not supported by BitBlt() Product: Wine Version: 1.7.19 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdi32 Assignee: wine-bugs(a)winehq.org Reporter: sashoalm(a)gmail.com Created attachment 48892 --> https://bugs.winehq.org/attachment.cgi?id=48892 Demo project. When a rotation is specified using the XFORM matrix, and later a bitmap is drawn using BitBlt(), it is rotated in Windows, but it is not rotated in Wine (it seems to be scaled instead).
