Plugins for PDF to be installed for Qt

harsha123

What plugins we need to install in our system for the Qt cpp to create pdf file using QAxWidget.

Christian Ehrlicher

There is no plugin needed to use QAxWidget in Qt.

harsha123

Sorry, it is QAxObject not QAxWidget, i think some plugins are missing to create a PDF file in Qt thats y i am asking this...
Like when i run the code to create PDF it is creating error that is because of not having plugins.

But Qt does not create PDFs. You just call an ActiveX object in another program which then creates a PDF. So you must make sure that this program is able to create PDFs. Has nothing to do with Qt.

And what "error" is this showing you?

Maybe this error is coming from the Word itself you access via QAx... saying it needs something set up in order to convert to PDF, I don't know? In your other threads on this I did ask you to verify you can do the export to PDF from within Word yourself, before you try to do it from Qt QAx...: did you test that?

harsha123

when i run in one system it is working , but in other system i ma getting this error

QAxBase::dynamicCallHelper: ExportAsFixedFormat(QVariant,QVariant,QVariant): No such property in [Microsoft Word Document]
Candidates are:
Email
EmbedLinguisticData
EmbedSmartTags
EmbedTrueTypeFonts
Endnotes
EnforceStyle
Envelope

Donno the reason behind this.

You never said before it is working on one system but not on another, that is new (important) information......

One more time: on the "other, non-working" system, have you or have you not tested you can do the PDF export from Word outside of Qt? And, did you try the similar export-to-PDF but from Excel instead on that system?

harsha123

yesterday after knowing the plugin issue i tried with different system then the same code is working, but in the old system it is not working, Reason is not know trying to find out the solution.

Christian Ehrlicher

This is for sure not Qt problem since ExportAsFixedFormat is an ActiveX call in Excel and therefore the error message comes from there, not Qt.

JonB

@Christian-Ehrlicher
The actual error appears to be that QAxBase::dynamicCallHelper() is not finding ExportAsFixedFormat as an "exported Automation method" in the installed Word on some particular machine. Why I do not yet know, I'd like to know whether the similar Excel call does or does not work.....

harsha123

no with excel call also it is not working this issue is with only one system.

OK, I've had a quick look at this. If you Google e.g. Word EmbedTrueTypeFonts you come to https://docs.microsoft.com/en-us/office/vba/api/word.document.embedtruetypefonts. If you look through the index on the left that is indeed a property. But ExportAsFixedFormat is a method, at https://docs.microsoft.com/en-us/office/vba/api/word.document.exportasfixedformat. I am unsure whether the error message referring to a "property" has or has not looked for it as a method. You might try with another method from there, such as Save() or Repaginate(), to see whether those do work as "methods"?

harsha123

when i use save file getting created but when try to open the file it is showing some thing went wrong ,i didnt work on Repaginate i will try that once..

JonB

@harsha123
One thing: are the versions of Word the same on both machines? Same version of Word, and not one has Microsoft/Office 365 installed locally while the other uses it only from the web?

harsha123

Yeah in both systems word versions are different in one system (non working) it is 2003 and in other system it is 2019.

Christian Ehrlicher

So did you actually tried to save a doc in Word 2003 as PDF? Did it work? I would guess not because saving to PDF was added later...

JonB

@harsha123
Ahhhhhhhhhhhhhhhhhhhhhhhhhh. It really helps if you check and state this in the first place!

https://stackoverflow.com/questions/60342174/word-exportasfixedformat claims to have it working in Word 2019. It might be worth a try passing all the same number of parameters as you see in that example code, in case 2019 ExportAsFixedFormat requires more parameters than before, i don't know.

P.S.
Only the first 2 parameters are mandatory. Try ExportAsFixedFormat(QVariant,QVariant) or whatever it is you presently have but omit the third parameter for "OpenAfterExport", just in case that works instead (though I don't think so, but worth a try).

harsha123

Ok u mean in working system i need to install 2003 version and check once, because with 2019 it is working

Do you mean NOT working??

WAIT

one system (non working) it is 2003

OMG. Word 2003 is too old to have ExportAsFixedFormat, no wonder!! (And probably does not export to PDF at all; I did ask you to verify that it worked on the failing system just from within Word, forget about Qt?) Why not say that from the outset? Who in the world uses Word 2003 in 2022...? This is your whole issue...... Please supply such relevant information in the first place when you ask a question, this whole thing has been a wild goose chase.....

harsha123

yes not working with 2003,ok i thought the reason i because of QT
