Only pre-win7 systems return E_INVALIDARG for invalid values, and only pre-vista systems accept FVM_AUTO as a view mode, others fall it back to FVM_ICON. Let's switch to modern behaviours, so that we don't need additional code for handling that when using it to implement IExplorerBrowser_SetFolderSettings(). --- dlls/shell32/shlview.c | 27 +++++++++++---------------- dlls/shell32/tests/shlview.c | 24 +++++++++++++++++++----- 2 files changed, 30 insertions(+), 21 deletions(-)
