This is Learning Purpose Only

I want to explore and learn the MSVC with Qt. Not specific to anything as Desktop apps (= pure MSVC) or Metro apps (= MSVC WinRT)

I just want to try and build the Qt App from below Options provided in MSVC 2019.

So you want to use your Visual Studio IDE to build Qt apps?

In that case, you don't need to use the Qt Creator IDE. Just click "Qt GUI Application" in your screenshot.

Hi @JKSH ,

Jup, I want to use VS IDE to build Qt.
I did try "Qt GUI Application" by selection default modules

• Core,
• GUI,
• Widgets,

And on "Next" i get

How to set the Object Reference ?

@Pradeep-P-N Why did you install Qt 5.9.2 and not the latest stable version (5.12.3)? I'm not sure that old version is going to work with latest Visual Studio.

That is not a configuration problem.

That is a .NET programming error. It means something is trying to deference a null object: https://stackoverflow.com/questions/4660142/what-is-a-nullreferenceexception-and-how-do-i-fix-it

Unfortunately, it doesn't look like there's an easy way to find out where that error occurs.

If you have a spare PC, I suggest you install the latest Visual Studio, install the latest Qt VS Tools, and install the latest Qt on it. Then see if it works.

@jsulm since about a week, the latest LTE version is 5.12.4 just fyi
;-)

Hi @jsulm thank you.
I was just trying. Yes i agree that version compatibility issues may come.
But my intention was to find the solution, so that it might help some one else also who can try with old Versions of Qt.

Right now, you are experiencing lots of issues. We can't tell whether the issues are being caused by version incompatibilities or not.

I recommend you try to get it working with the latest versions first. After that, you can spend time trying to make it work with older versions.

Hello! Also please note about this issue with Qt and MSVC2019: https://bugreports.qt.io/browse/QTBUG-75280
It is still not fixed yet. For now it is better to use Qt with MSVC2017.

@Cobra91151
Thanks.
Jup, shifted to MSVC 2017.

@JKSH Can you put this information (Qt msvc2017 is binary compatible with msvc2019 package) to a more prominent place on the Qt pages, e.g. the download section, to be visible for all people seeking the latest and greatest version of Qt for their compiler? I was looking for this kind of information at least 1 hour. Cheers, Volker

I don't have access to the Qt website, sorry. Please submit your request to https://bugreports.qt.io (under "Qt Project Website")

The compatibility information comes from Microsoft directly: https://docs.microsoft.com/en-us/cpp/porting/binary-compat-2015-2017?view=vs-2019

[volker]

@JKSH Ah, now I see. I must have missed that fact when downloading/installing MSVC2019. Will file a request to the bug reports. Cheers, Volker

[volker]

@volker Done. Request can be found under following link
