How to debug through Acrobat.dll

[kundan24352562]

Hello,

I am having a problem with searching through comments in highlight annotation.

Problem behavior is somewhat strange.

First time when it searches through the comments, it does it successfully.

When I search second time and scroll a document little bit then Acrobat crashes.

When I try to debug, at some point, it gives me error that Acrobat.pdb is not loaded and hence I can not debug it further.

I want to debug it further (in Acrobat.dll) because I think I can get some clue for crash.

How can I load this Acrobat.pdb and debug in Acrobat.dll?

Here is my code to search though the comments:

ASText searchKey = ASTextNew();
searchKey = ASTextFromUnicode((ASUTF16Val*)reqText, kUTF16HostEndian);
SearchQueryDataRec srcQuery;
memset(&srcQuery, 0, sizeof(SearchQueryDataRec));
srcQuery.size = sizeof(SearchQueryDataRec);
srcQuery.query = searchKey;
srcQuery.type = kSearchActiveDoc;
//Search through comments of Highlight annotation
srcQuery.scope = kSearchDocumentText | kSearchMarkup;
srcQuery.path = NULL;
srcQuery.fs = NULL;
srcQuery.maxDocs = 1;
ASBool ret = SearchExecuteQueryEx(&srcQuery);
ASTextDestroy(searchKey);

Thank you in advance!

Any updates on this?

For your more information, when Acrobat crashes when I scroll, and if use the Acrobat debug option to debug it, it gives me below error:

But for my above logic, there is not any callbacks that I have written.

And Acrobat crashes when It is scrolled somewhat.

What is the cause of this error?

Thank you in advance!

Any update please?

The application crashes somewhere in Acrobat, not in your own plug-in. You don't have the source code to Acrobat, and therefore cannot debug what is happening inside Acrobat. However, chances are that something you do in your plug-in is causing this crash. Do you have appropriate DURING/HANDLER wrappers around anything that could potentially cause an exception? You can step through your code to figure out which line in your plug-in is causing the crash, and then investigate if you are using that API call correctly.
