Delete document cards from Knowlede Directory

Question

Hi,
I am trying to delete a card from the knowledge directory (document folder) but nothing happens (ie. the card is supposed to get deleted) when I run the following code:
IPTQueryResult qrCards = Folder.QueryCards(PTPROPIDS.PT_PROPID_OBJECTID, true, PT_PROPIDS.PT_PROPID_OBJECTID, 0, -1, null);
for (int i = 0; i < qrCards.RowCount(); i++)
int objectId = qrCards.ItemAsInt(i, PT_PROPIDS.PT_PROPID_OBJECTID);
Object[] status = iptSession.GetCatalog().DeleteCards(objectId);
for (int y=0;y < status.length; y++)
MessageBox.Show("status: " + status[y]);
status returned: -2147024891
Am I missing something?
Thanks in advance.

If you're connecting to a portal instance with the Portal Server API (as it appears you are), then you should probably be selecting the Portal component in PTSpy. You can tell from the startup which component to select, as it will say something like:
OpenLog: verposity level = 2
OpenLog: Registered application name: ConfigInitialization (local machine only)
OpenLog: Registered application name: portal.[machinename].Administrator (local machine only)
The last application name is what you'd use. Make sure you are recording on the machine running the custom app.
Since you can see it in both browse and edit mode, we know that the search index and the database both know of the card, so it can't be that it thinks the card is missing. At this point, you'd have to go through the PTSpy recorded when you run your app. You should start it right before you initiate the delete, and shut it off after the PTSpy stops recording new lines. You might be able to search for the error code, otherwise you'd have to go line by line to find something related to permissions, though other types of errors (not found, network access problems) might return the access denied message.
