using QAxWidget to open pdf, printing is not working

I think you may have tried this, and I admit that you say the call returns true so it may not be a problem, but I wouldn't have passed a path with forward slashes to LoadFile, I would have passed a Windows path with backslashes.

P.S.
Otherwise, just maybe it has read the document but isn't showing a page? For all I know maybe you need SetCurrentPage(1). Or what about SetShowToolbar(true) or the SetPageMode("bookmarks") just to see whether either of these appear?

Hi, totally agreeing with @JonB, forward slashes can spell trouble.

Also, maybe that particular pdf has a problem (just guessing) why not try another PDF (from Wikipedia):

qDebug() << pdf->dynamicCall("LoadFile(QString)", "http://tripleboot.org/Pictures/GettysburgAddress.pdf").toBool(); // return true

@JonB Thanks for your reply. I will try it.

@JonB still the same gray background. I used

pdf->dynamicCall("SetCurrentPage(1)");
pdf->dynamicCall("SetPageMode(\"bookmarks\")");

nothing happened.

I also use

dumpcpp "{CA8A9780-280D-11CF-A24D-444553540000}"

to generate acropdflib.cpp and acropdflib.h file.
But when I use these file in my project, it can't complie.

unknown type name '_IAcroAXDocShimEvents'.

@hskoglund Hi thank you for your advice. I try another pdf file, but not work.

Hmm, COM technology is old, maybe you're compiling/building for 64-bits?
Try 32-bit, it should work better.

[hskoglund]

Yes, just to confirm, I built the app both in MSVC2019 32-bit and 64-bit versions. Both version gave the same qDebug() output and no errors.
But the 64-bit version returns only a grey page (same as you got).
The 32-bit version works.

P.S: More users have had this problem, eg. https://forum.qt.io/topic/119455/qaxwidget-adobe-pdf-reader-working-with-kit-qt-5-14-1-msvc2017-32-but-not-with-kit-with-qt-5-14-1-msvc2017-64

@hskoglund Thanks for your reply. I will try it tomorrow. Very appreciate.

@hskoglund Yes, it works. Build with MSVC2019 32-bit works. Thanks for your help.
