How to disable both the Recent and Frequent categories of a custom Jump List (ICustomDestinationList)

Question

Hello!
When I create instance of ICustomDestinationList , then start the Jump Lists's building session via ICustomDestinationList::BeginList, then DO NOT invoke ICustomDestinationList::AppendKnownCategory, then end the building session via ICustomDestinationList::CommitList, then invoke SHAddToRecentDocs, my custom Jump List still displays Recent category, but I didn't "turn on" it via ICustomDestinationList::AppendKnownCategory. Why? And is there a way to disable both Recent and Frequent categories?

Answer 1

I cannot reproduce this problem with the MS SDK sample (does not call SHAddToRecentDocs):
CustomJumpList

Screencopy of the context menu (french) =>

Answer 2

Ok, looks like I discovered the next thing: if the Frequent and any custom categories aren't set then the Recent category is displayed despite it was not enabled explicitly (via ICustomDestinationList::AppendKnownCategory).

IMHO if "it's not a bug, it's a feature" then such behavior should be explicitly described in the documentation because it's counter-intuitive I think.

Answer 3

Hello @Nikita Provotorov ,

DO NOT invoke ICustomDestinationList::AppendKnownCategory, then end the building session via ICustomDestinationList::CommitList

The Recent category will not displayed. You can confirm it via AutomaticJumpList sample with this line pcdl->AppendKnownCategory(fRecentSelected ? KDC_RECENT : KDC_FREQUENT); commented out.

invoke SHAddToRecentDocs, my custom Jump List still displays Recent category

This is expected because the SHAddToRecentDocs function adds a document to the shell's list of recently used documents. If you don't want Recent category don't call this function.

Thank you!
