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! Clap

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. Cry

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:

Cheers and welcome here,
Ingo

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:
