for (int i=optionNum; i>=1; --i)

{

int optionID = DPL.GetOptionalContentGroupID(i);

DPL.DeleteOptionalContentGroup(optionID);

}

You should first re-sequence the loop. You should always start with the highest value and descend from the top down when deleting, because deleting the value i makes the next item become i. Also the content group ID index base is documented as 1, not 0.

Hi, I use the following code to delete the optionalcontentgroup, however it does not remove the optionalcontentgroup. Could somebody give me some suggestion, thanks! look forward to your replay.

DPL.LoadFromFile(L"contentstream.pdf", L"");

int contentNum = DPL.ContentStreamCount();

int optionNum = DPL.OptionalContentGroupCount();

for (int i=0; i<=optionNum; ++i)

{

int optionID = DPL.GetOptionalContentGroupID(i);

CStringW optionalName = DPL.GetOptionalContentGroupName(optionID).c_str();

DPL.DeleteOptionalContentGroup(optionID);

}

DPL.SaveToFile(L"no_option.pdf");
