Using the new Fivhcm.lib didn't work with me either.

I noticed, that the process of my running .exe consumes a lot of memory.
If I save a preview of 47 pages to a pdf, the process grows to 1.409.964KB and the resulting .pdf gets a size of 28.454KB
With 63 pages I get the error that is described here. At that moment the process has a size of 1.774.336KB and the corrupted .pdf 34.836KB
If I try the same with even more pages, the process always crashes when the memory usages exceeds about 1.774.000KB and the corrupted .pdf is always about 35.000kb.

Furthermore I noticed, when using the word conversion to pdf (used by fwh) the pdf even with 1621 pages has only a size of 4.720KB

Maybe these figures are of help in finding the cause of the errors.

Now the function works very good. But the question "open the pdf.....?" should not prompt! This must do the programmer, if he wish this.

Syntax:
Code (fw): Select all Collapse
FWSavePreviewToPDF( oPreview, [cPDF], [lOpen] )


First parameter is compulsory.

If second parameter is nil, the function prompts to provide a file name to save.

if the third parameter is
nil -> Prompts whether to open the file or not
.t. -> Opens the pdf without prompting
.f. -> does not prompt and does not open pdf
