1.25a WINDOWS kbprg kbfixlist kbbuglist

The information in this article applies to:

• Microsoft Win32s, version 1.25a

The following is a list of the known bugs in Win32s version 1.2 that were fixed in Win32s version 1.25.

• GlobalAlloc(GMEM_FIXED) from 32-bit .EXE locks memory pages. It is more efficient to use GlobalAlloc(GMEM_MOVEABLE) and call GlobalFix() if necessary.
• WINMM16.DLL has no version information.
• CreateFileMapping() with SEC_NOCOMMIT returns ERROR_INVALID_PARAMETER.
• PolyPolygon() does not close the polygons.
• OpenFile() only searches the current directory when only a filename is given, not the application directory, the system directory, the windows directory, or the directories listed on the path.
• GetFileInformationByHandle() doesn't return the correct file attribute.
• GlobalUnlock() sets an error of ERROR_INVALID_PARAMETER.
• lstrcmp()/lstrcmpi() do not use the collate table correctly.
• FreeLibrary() in DLL_PROCESS_DETACH crashes the system.
• FindResource(), LoadResource(), GetProcAddress(), GetModuleFileName(), EnumResourceNames(), and other APIs, fail with a NULL hInstance.
• sndPlaySound() with SND_ASYNC | SND_MEMORY may cause a crash or may work poorly.
• Thread Local Storage (TLS) data is not initialized to 0 in TlsAlloc().
• The pointer received in the lParam of WM_INITDIALOG in the common dialog hook function becomes invalid in the following messages if the pointer is "remembered" in a static variable.
• Stubbed API GetFileAttributesW() does not return -1 on error.
• Code page CP_MACCP not supported.
• Invalid LCIDs are not recognized.
• CreateFile() fails to open an existing file in share mode.
• GetLocaleInfo() for locale returns system defaults from WIN.INI.
• GetVolumeInformation() fails with ERROR_INVALID_NAME for volumes without a label.
• VirtualProtect() may miss the last page in an address range.
• GetLocaleInfo() returns incorrect information for most non-US locales.
• ANSI/OEM conversions always use code page 437.
• GetProcAddress() for printer driver APIs is case sensitive.
• The LanMan APIs are unsupported, but they return 0, which indicates that the API was successful. They should return NERR_InvalidAPI (2142).
• CreateFileW() returns 0 instead of -1 (HFILE_ERROR).
• lstrcpyn() copies n bytes from source to destination, then appends a NULL terminator, instead of copying n-1 bytes and appending the NULL terminator.
• GetDriveType() doesn't report detecting a CD-ROM or a RAM DISK.
• CRTDLL calls TlsFree() upon each process detach, not just the last.
• If a DllEntryPoint calls FreeLibrary() when using universal thunks, the system can crash.
• Not all 32-bit DLLs have correct version numbers.
• GetCurrentDirectory() returns the wrong directory after calling GetOpenFileName(). The workaround is to call SetCurrentDirectory(".") right after returning from the call to GetOpenFileName().
• RegEnumValue() and other Registry functions return ERROR_SUCCESS even though they are not implemented. Win32s implements only the registry functions supported by Windows.
• AreFileApisANSI()/SetFileApisToANSI()/SetFileApisToOEM() are not exported. AreFileApisANSI() should always return TRUE, SetFileApiToOEM() should always fail, and SetFileApiToANSI() should always succeed.
• SetLocaleInfoW()/SetLocateInfoA() are not implemented.
• GetScrollPos() sets the last error if the scroll position is 0.
• SetScrollPos() sets the last error if the last scroll position is 0.
• LoadString() leaks memory if the string is a null string.
• GetFileVersionInfoSize() fails if the resource section is small and close to the end of the file.
• MoveFile() doesn't call SetLastError() on failure or sets a different error than on Windows NT.
• SetCurrentDirectory() does not work on a CD-ROM drive.
• GetFileVersionInfoSize() fails if the 2nd parameter is NULL.
• WSOCK32.DLL is missing exported stubs for unimplemented APIs.
• Win32s fails to load 64x64 monochrome (black and white) icons.
• CreateFile() fails when called with a filename with an international character.
• GetCurrentDirectory() returns an OEM string.
• PrintDlg() causes GP fault if hDevMode!=NULL and another printer is selected that uses a larger DevMode buffer.
• Unicode resources are not properly converted to 8-bit characters.
• CreateDC() returns an incorrect DEVMODE. This can cause a variety of symptoms, like the inability to do a Landscape Print Preview from an MFC application or the displayed paper width and height not changing, even when you change the paper size.
• OpenFile() fails on filenames with OEM characters in the name.
• WNetCancelConnection() should be supported similar to NetAddConnection().
• GetDriveType() fails on a Stacker 3.1 drive.
• SetCurrentDirectory() fails on Novell client machines.
• GetProp() returns 0 in the second instance of an app in certain cases.
• fopen(fn, "w") fails on second call.
• TLS indices allocated by a module are released when that module is freed.
• CreateWindow() handles STARTUPINFO incorrectly if the application starts minimized.
• CreateFile() creates files with incorrect attributes.
• Resource sections are now read/write to emulate the behavior of Windows NT and Windows 95.
• Removed the 128K stack limitation.
• CompareStringW() sometimes uses incorrect locale, primarily Swedish and other Scandinavian locales.
• Added dummy _iob to CRTDLL for applications that reference standard handles.
• Added support for OPENCHANNEL, CLOSECHANNEL, SEXGDIXFORM, and DOWNLOADHEADER escapes.
