ntdll: - `NtQuerySystemInformation` `SystemBootEnvironmentInformation` - `NtQuerySystemEnvironmentValueEx` kernel32: - `GetFirmwareType` - `GetFirmwareEnvironmentVariableExA` - `GetFirmwareEnvironmentVariableExW` - `GetFirmwareEnvironmentVariableA` - `GetFirmwareEnvironmentVariableW`.

[PATCH 0/1] MR6443: comdlg32: allow entering a filter in the itemdlg file name field
by Charlotte Pabst (＠CharlottePabst) 06 Sep '24

06 Sep '24

This fixes a bug in EastMoney, which calls SetFileTypes() with a COMDLG_FILTERSPEC structure in which pszSpec = L"" followed by SetFileName(L"*.fml"). In windows, this matches all *.fml files. In wine, this matched no files. Before this patch, wine did not use filters from the file name field (marked as a FIXME) and a file type entry with an empty spec would match no files (as opposed to leaving the current filter unmodified). The exact rules worked out by testing in a Windows 10 VM seem to be: Current filter is initially empty and can be set by typing a filter into the file name field (or SetFileName) or selecting an entry from the file type menu (or SetFileTypeIndex). Selecting a file type entry with an empty spec leaves the current filter unchanged. Selecting a file type entry with a non-empty spec clears the file name field if it currently contains a filter. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6443
