Question

"Paging" with CF_OPERATION_TRANSFER_PLACEHOLDERS_FLAGS does not seem to work as documented any more?

sysadmin 140

The documentation on CF_OPERATION_TRANSFER_PLACEHOLDERS_FLAGS describes a process to allow the software to "page" whereby you send a flag of NONE until you have finished returning all placeholders

However, I am now finding that returning NONE makes explorer hang, no subsequent requests are triggered

This was previously working, but no longer?

I've never had any joy with the feedback hub, so I'd recommend that you also submit feedback on the documentation and if you have the ability to do so, raise a support call through MS (paid) support - though as it seems to be reproducible hopefully you shouldn't be charged.

@David Lowndes how do we do that again? We do have paid support, but it only entitles us to priority Q&A

Sorry, I don't know. It may depend on where you are and what support you have, you could try here.

Hello @sysadmin ,

Since you have paid support, you can try utilizing the Microsoft EngageHub portal to initiate a formal support request for this API regression.

Let me know if you need any further assistance with this.

Hello @sysadmin ,

I have tested this on my side and encountered the exact same behavior you described.

The temporary workaround I currently recommend is to return all placeholders in a single response and use the CF_OPERATION_TRANSFER_PLACEHOLDERS_FLAG_DISABLE_ON_DEMAND_POPULATION flag to successfully complete the operation.

Since this actual behavior deviates from the official documentation, I recommend submitting a report via Windows Feedback Hub.

I hope this information helps. If you found this response informative or helpful, please consider following this guide to provide feedback.

Thank you.
