Hi Alain,
The problem here, as Steffen has mentioned, is that TypeDetection does
not always detect a corruption in files. Actually the main intention of
TypeDetection is not to detect whether a document can be loaded, but to
suggest a filter that looks to be most suitable.
In case of currupted file or an unknown format, the TypeDetection still
might suggest a filter that looks to be suitable, and the pure
text-filter is always suitable. Moreover, fast any document can be
loaded as pure text-file.
As for the new API, from my point of view it does not make much sense,
since the document has to be loaded anyway to guarantee that it is
loadable. And the pure text filter can load everything anyway.
Best regards,
Mikhail.

Thanks Steffen,
I more or less hoped that TypeDetection could be used in that purpose :(
Is this the right place to suggest a
sal_Bool com::sun::star::frame::XComponentLoader::checkComponentFromURL()
API?
cheers,
AR

Hello Alain,
I do not think so. You could check the extension of the file, if it's
one of the known extensions of OOo. But you surely thought of that. If
we are talking about possibly corrupt files, then I see no other way
than opening them and see if it works.
Regards, Steffen

Hi,
I need to know if a user selected file can be loaded by OOo.
My current (working) implementation tests if OOo can load the file
(in hidden mode). It is costly, specially when the answer is yes, as
the file will actually be loaded before return. Is there a lighter
way to get the answer?
inline bool CanLoad(LPCWSTR sPath)
{
Reference<XComponent> xDoc;
using com::sun::star::frame::XComponentLoader;
Reference<XComponentLoader>
xLoader(Instance<XComponentLoader>(L"com.sun.star.frame.Desktop"));
if (xLoader.is())
try
{
using com::sun::star::beans::PropertyValue;
using com::sun::star::beans::PropertyState_DIRECT_VALUE;
PropertyValue pvHidden(L"Hidden", 0, Any(true),
PropertyState_DIRECT_VALUE);
Sequence<PropertyValue> sPV(&pvHidden, 1);
using com::sun::star::frame::FrameSearchFlag::CREATE;
xDoc = xLoader->loadComponentFromURL(GetPathURL(sPath).Complete,
L"_blank", CREATE, sPV);
}
catch (Exception e)
{}
return xDoc.is() ? xDoc->dispose(), true : false;
}Thanks,
AR
