Count bookmarks using DAOpenFile

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I use DAOpenFile for getting the number and format of all pages of the PDF. That works very fine, also with very big files and page formats!

But sometimes I need to count the number of the bookmarks (outlines).

I know that I can use .LoadFromFile and then .PageCount() and .OutlineCount(), but then after loading several files the .LoadFromFile gives fileHandle 0. 
I use for each document when I am ready .RemoveDocument().

2 questions:
1. Is there or will there become a "DA-version" of the OutlineCount() ?
2. If not, what need I to do to get the OutlineCount() without problems?

Thanks,
Evert-Jan

	Hi Jan! Could it be that you're working on a list of files in a loop with LoadFromFile? Perhaps (with very large files) you throw a second filename into LoadFromFile but the first file still isn't completely loaded? Perhaps you should think in this direction...? If you're suggesting a further development of QuickPDF you should enter this Link: http://www.quickpdflibrary.com/support/support-query.php Cheers and welcome here, Ingo Edited by Ingo - 11 Apr 12 at 10:17AM

	Hi Ingo, I indeed use a loop to process a list of PDF files. For each file a call this function: // QuickPDF private string HandlePDF(string filename) { try { int formaatNr = 0; // Open the file, get a file handle int fileHandle = 0; fileHandle = qp.LoadFromFile(filename, ""); if (fileHandle == 0) { return filename + ": cannot open file.\r\n"; } int aantalPags = qp.PageCount(); if (aantalPags == 0) { qp.RemoveDocument(fileHandle); return filename + ": filehasn't pages.\r\n"; } aantalBMs += qp.OutlineCount(); for (int p = 0; p < aantalPags; p++) { // Get a reference to the first page and get the formats int pageReference = 0; double pageWidth = 0; double pageHeight = 0; int rotation = 0; pageReference = qp.SelectPage(p + 1); pageWidth = qp.PageWidth(); pageHeight = qp.PageHeight(); rotation = qp.PageRotation(); if (rotation == 90 \|\| rotation == 270) { double d = pageWidth; pageWidth = pageHeight; pageHeight = d; } double br = pageWidth; double hg = pageHeight; br = br * 0.3527; // convert from units to mm hg = hg * 0.3527; } // Close the file qp.RemoveDocument(fileHandle); } catch (Exception ex) { } return ""; } Is this the correct way, or how can I know that a file is loaded? Thanks, Evert-Jan

	Hi Jan! If LoadFromFile returns with value 0 you can use LastErrorCode to check where's the real problem: http://www.quickpdflibrary.com/help/quickpdf/LastErrorCode.php Cheers, Ingo
