Hi,
I am making a bread crumb bar in Delphi and having some problems regarding sorting the dropdown of the bread crumbs.
Strangely enough, even Vista is not consequent when showing these items.
I have tried many ways to figure out what is system folders, what is zip files and what is normal folders. It seems like an easy task but so far I have not found any good way of doing it.
One way is to use TypeDisplayName from TSHFileinfo but these are localized names so I can not be sure they will be in correct order in every language.
Here is the code I use to fill the menu:
bool:= IsDesktop(SelectedPIDL);
if bool then
OleCheck(SHGetDesktopFolder(CurFolder))
else
OleCheck(DesktopShellFolder.BindToObject(SelectedPIDL, nil, IID_IShellFolder, Pointer(CurFolder)));
if CurFolder.EnumObjects(0, SHCONTF_FOLDERS, EnumIDList) = NOERROR then
begin
while EnumIDList.Next(1, CurPidl, Fetched) = S_OK do
begin
FName:= GetDisplayName(CurFolder, CurPidl, SHGDN_NORMAL);
Text:= GetPIDLNameForAddressBar(CurFolder, CurPidl);
if bool then
Text:= PSpecialFolderItem(SpecialFolders[0]).Name + '\' + Text;
if Text[Length(Text)] <> '\' then
Text:= Text + '\';
NewPidl:= ConcatPIDLs(SelectedPIDL, CurPidl);
SHGetFileInfo(PChar(NewPidl), 0, SFI, SizeOf(SFI), SHGFI_ATTRIBUTES or SHGFI_PIDL or
SHGFI_SYSICONINDEX or SHGFI_TYPENAME);
n:= SFI.dwAttributes;
MenuList.Add(GetAttr(n) + FName);
AddMenuItem(Text, FName, SFI.iIcon);
CoTaskMemFree(CurPidl);
CoTaskMemFree(NewPidl);
end;
end;
CoTaskMemFree(SelectedPIDL);
Any solution for how to get the correct sorting order? It is strange there is no way in dwAttributes of TSHFileInfo to tell if a folder is a system folder.
