Error handling in RpcBindingVectorFree (dlls/rpcrt4/rpc_binding.c)
by Gerald Pfeifer Nov. 22, 2020

Nov. 22, 2020

Looking at RPC_STATUS WINAPI RpcBindingVectorFree( RPC_BINDING_VECTOR** BindingVector ) { RPC_STATUS status; ULONG c; TRACE("(%p)\n", BindingVector); for (c=0; c<(*BindingVector)->Count; c++) { status = RpcBindingFree(&(*BindingVector)->BindingH[c]); } HeapFree(GetProcessHeap(), 0, *BindingVector); *BindingVector = NULL; return RPC_S_OK; } we currently always ignore the outcome of RpcBindingFree and return RPC_S_OK. However, there is one case where RpcBindingFree returns something different (which is if *Binding is null when RPC_S_INVALID_BINDING is returned). What is the proper way of handling this? Just keeping the code as is and removing the unused status variable? Breaking the loop once RpcBindingFree returns something different from RPC_S_OK? Continuing and returning the first / the last status different from RPC_S_OK? Gerald

ntoskrnl.exe: unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces

Sept. 28, 2018

Dear all, While test another online bank with wine ActiveX, I got an unimplemented fuction of ntoskrnl: IoGetDeviceInterfaces, I found it listed in http://source.winehq.org/WineAPI/ntoskrnl.html as a stup, so I can't understand this log: wine: Unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces called at address 0x7b839552 (thread 0022), starting debugger...

ODBC Databases: Jet/Access success
by Barry Bird June 14, 2018

June 14, 2018

Good Afternoon. In section 3.3.6.2 of your User Guide you ask readers to report successes with databases other than MS SQL. Well here's one (I know Access 2000 can work with Wine, but this doesn't require Access): How to set up Wine to enable Windows programs that read and write to Jet (Access) databases using ODBC. I write such programs in C and use the API defined in ODBC API Reference http://msdn.microsoft.com/en-us/library/ms714562%28VS.85%29.aspx They work fine on Windows and only require Mingw to be installed to compile and link them, both for console programs and those using Windows SDK. You then can write interactive programs in C which use a full-featured SQL database which comes bundled with Windows. No need to purchase Access. With the set-up below they will also run on Linux (Kubuntu 9.04) and Wine 1.1.26. You need to update the registry to install the Access drivers. Under Windows, export from the Registry to *.reg files the registry entries - HKLM\Software\ODBC - HKLM\Software\Microsoft\Jet all subsidiary keys and values come with them. You can carefully edit these files to remove drivers and DSNs you don't need. Import these files using the registry editor in wine: wine regedit.exe. You need to bring across from Windows to Windows\System32 under wine: clbcatq.dll comres.dll expsrv.dll msjet40.dll mswstr10.dll msjter40.dll msjint40.dll msjtes40.dll msrd3x40.dll odbc32.dll odbccp32.dll odbcji32.dll odbcjt32.dll odbcad32.exe odbcint.dll odbctrac.dll vbajet32.dll Register this server in wine: wine regsvr32.exe msjtes40.dll No need to install MDAC. To use Windows ODBC drivers, you have to override Wine's odbccp32.dll and odbc32.dll with the native versions because the Wine versions are currently wired directly to Linux's unixodbc. This can be done by setting up the ODBC Data Source Administrator odbcad32.exe using winecfg: - Add the program to the Applications tab - then in the libraries tab, pick from 'New override for library' drop-down odbc32.dll and odbccp32.dll add them and edit them to be Native for Windows. Then if you do wine odbcad32.exe this brings up the ODBC Data Source Administrator window as in the Windows Control Panel If needed, set up (System) DSNs using this program. Bring across the programs and *.mdb database files from Windows. Using winecfg, you need to set up each program you want to run with overrides for odbc32.dll and odbccp32.dll (Applications and Libraries tabs) as above. The programs should then run as they did in Windows but perhaps a bit slower with: wine Odbc-prog.exe This has been tested twice on a clean .wine install. I cannot vouch for support of all API and SQL facilities however. I hope someone finds this useful. Barry Bird

IMM / IME work
by Aric Stewart June 16, 2016

June 16, 2016

Hello all, I know this will only interest a small portion of you but thought i would give a quick update on the state of IMM32 since I have brought it to a major milestone. All the main patches are in which now separate IMM32 and IMEs. There is still more work to do but the major framework is in place. X11 XIM processing should be unchanged. However wine can now begin to load native windows IMEs as well. I have tested with windows ATOK20 (a popular Japanese IME) and successfully had text processing in a fully IME aware application. There are still clear issues to resolve in many aspects of this processing but we have forward progress. ImmInstallIME does not work yet, nor does switching keyboards. So to get the native IME to work you need to add this registry key. [System\\CurrentControlSet\\Control\\Keyboard Layouts\\<keyboard layout>] "Ime File"=<IME filename> so for example for ATOK20 in Japanese i used. [System\\CurrentControlSet\\Control\\Keyboard Layouts\\e0010411] "Ime File"="ATOK20W.IME" I would love to hear how well things work. I am sure using native IMEs will quickly show us many places where IMM32 needs to be improved. One issues I am going to investigate next is that sometimes non x11drv ime initialization, if occurring too early, causes x11drv to fail to create windows. I have not investigated with the latest changes to xim.c (which may already correct this problem) but if you see this problem this patch may help and i believe the IME_UpdateAssociation(NULL) is already unneeded. diff --git a/dlls/winex11.drv/xim.c b/dlls/winex11.drv/xim.c index d4df9f7..0c98136 100644 --- a/dlls/winex11.drv/xim.c +++ b/dlls/winex11.drv/xim.c @@ -475,7 +475,6 @@ static void X11DRV_OpenIM(Display *display, XPointer ptr, XP XUnregisterIMInstantiateCallback(display, NULL, NULL, NULL, X11DRV_OpenIM, wine_tsx11_unlock(); IME_XIMPresent(TRUE); - IME_UpdateAssociation(NULL); } thanks, -aric

DirectInput already has some internal abstraction layers for differnet joystick APIs, and has basic support for OSX joysticks. Does DInput have enough capabilities to access all the Xbox controller's features? My gut says no, otherwise MS wouldn't have created a new lib. I guess its worth checking though.

Wine 64 bit

Hello, Where would you find information on wine64 status for running 64 bit windows software under OSX. These days a lot of Windows programs are going 64bit to make use of the available memory. Its becoming necessary to have this capability. Many thanks Kevin

[PATCH] Mystery hang reduction -- clear new allocations
by mtewoodbury＠gmail.com Nov. 2, 2014

Nov. 2, 2014

From: Max TenEyck Woodbury <max+git(a)mtew.isa-geek.net> I was getting mystery frozen processes that cleared when a total screen redraw was forced. This has been reported numerous times over several years. It came and went with various releases. I have been getting it consistantly recently. I had an idea that it might have something to do with partially uninitialized drawing data structures, so I started adding HEAP_ZERO_MEMORY flags in various places. This particular set cleared the problem, at least for now... diff --git a/dlls/wined3d/vertexdeclaration.c b/dlls/wined3d/vertexdeclaration.c index cf5378c..cf1c814 100644 --- a/dlls/wined3d/vertexdeclaration.c +++ b/dlls/wined3d/vertexdeclaration.c @@ -178,7 +178,8 @@ static HRESULT vertexdeclaration_init(struct wined3d_vertex_declaration *declara declaration->parent = parent; declaration->parent_ops = parent_ops; declaration->device = device; - declaration->elements = HeapAlloc(GetProcessHeap(), 0, sizeof(*declaration->elements) * element_count); + declaration->elements = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, + sizeof(*declaration->elements) * element_count); if (!declaration->elements) { ERR("Failed to allocate elements memory.\n"); @@ -316,7 +317,7 @@ static unsigned int convert_fvf_to_declaration(const struct wined3d_gl_info *gl_ has_psize + has_diffuse + has_specular + num_textures; state.gl_info = gl_info; - state.elements = HeapAlloc(GetProcessHeap(), 0, size * sizeof(*state.elements)); + state.elements = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, size * sizeof(*state.elements)); if (!state.elements) return ~0U; state.offset = 0; state.idx = 0; -- 1.8.0.rc0.18.gf84667d

The function never returns E_OUTOFMEMORY. You can't test it in wine tests suite but you can see it by calling the function in loop until system runs out of memory and then checking the error. You should simply try to allocate the string and if it fails return VBSE_OUT_OF_STRING_SPACE. Cheers, Piotr
