…
But is it relevant for your current problem?

Understanding why my build crashes and yours does not is actually more important to me than fixing the Doc Switcher issue.
I hardly use that feature but I suspect some other features may not work properly as well.

Here is the Dump file.

The other way would be to put a breakpoint on line 2243…

Should I build it as Debug instead of Release?

Thank you for further looking into it and for the detailed explanations. I do appreciate that.

Best regards.

I’m running windows7 inside a virtual machine and IE is of version 11.
IE might be an issue for your VS2017, MS had made dependencies
in the past so I wouldn’t be surprised if it is needed to run VS correctly.
But is it relevant for your current problem?

What makes me wonder is that you said, when clicking disable extension column first
you don’t have the problem which makes me think that the initialization is the same
and the listview control in general shouldn’t be the problem but if it already crashes
before doing initList something within init must have been corrupted already.
And in init is the InitCommonControlsEx which is basically responsible for
making listview available but … why should it work if you disable the extension first.

Can you make the dmp file available? Through your github page?
I’m curious what is going on.

The other way would be to put a breakpoint on line 2243 in NppBigSwitch.cpp,
the line with if (toShow) and then if either launchFileSwitcherPanel() or
launchFileSwitcherPanel->display(false) is reached use F11 to jump into
this function and then use F10 onwards and carefully check the variables when
the lines have executed. Sounds a lot but once you get familiar with it,
it looses all of its magic ;-)

I hope you’ve had a good day. Thanks again.

Well, it seems that line 95 is the culprit.

A shot in the dark:
You can see the message The content requires a new version of Internet Explorer in the Diagnostic Tools.
I hardly use IE directly but I have some applications using it; I still have IE 8 installed as it’s impossible to disable Clear Type in more recent versions.
Can that be somehow related? Or do you build NPP under Wine without even having IE?

I do appreciate your help.

I don’t know when you’re going to retire tonight. :)
I won’t be by my PC tomorrow and Saturday.

Best regards.

can you set a breakpoint onto line 100 in VerticalFileSwitchesListView.cpp
like here

run the project by pressing F5, once npp appears do the setting changes
and then when VS comes up with the breakpoint step through it with F10
until you receive the access denied exception, then we know which
part exactly throws that exception.

I’ve created a Dump file, opened it in VS and used “Debug with Native Only”.

Interestingly, if I check Hide Extension Column first and then Show - the crash does not happen.

Whenever you have some free time. Thanks again.

Best regards.

I’ve never used the Debugger. :)
It might also be some general setting I’ve modified in VS.
We’ll see tomorrow.

Thanks again and good night.

then I would say time to debug. Either run from within VS (copy everything to the build
directory) or attach it to the running exe, but then make sure the pdb files are found.
Just for info - I have to stay up early tomorrow so I have to stop here.
But if there is anything I could do we can follow up tomorrow night :-)

Claudia

Thanks again. Appreciated.

Thanks again for your time and effort.

If you have downloaded an official zipped package, could you replace the
official builded npp exe with the one you build and run it within this directory.

That is just what I have done. :)
Win 7 x32.

Best regards.

From the code I only could guess that there might be a problem with your configuration files.

If you have downloaded an official zipped package, could you replace the
official builded npp exe with the one you build and run it within this directory.

If this works then it indicates that one of your configuration files is corrupt.

If it doesn’t work … hmmm … which operating system do you run?

Thank you very much for the prompt reply. I do appreciate it.

The only thing I modified was from x64 to x86 and to Release instead of Debug.
No errors or warnings.

I’ve used it for a few days without any problem.
Trying today to display the Document List Panel, the crash happened.
It is consistent; whenever I try to check that option NPP crashes.

I downloaded a fresh portable NPP and replaced the binary with my build.

Best regards.

as I did - but no crashes so far
and is this reproducible?

Which VS version do you run?

Microsoft Visual Studio Community 2017 
Version 15.6.3
VisualStudio.15.Release/15.6.3+27428.2011
Microsoft .NET Framework
Version 4.7.02558

Installed Version: Community

Did you change something on the build process? Build events?
How do you start npp? From within the build directory?
x64 or x32 ? (I tested only x64)

Cheers
Claudia

Last week I installed VS 2017 Community and built NPP 7.5.6.
Thanks again for your help.

I tried today to check Preferences -> General -> Document List Panel - Show and NPP crashed.
Thinking it was due to some of my code changes, I downloaded the repository again and built it as is. The same result - NPP crashes.

Building:
I doubled clicked notepadPlus.vcxproj, was prompted to add support for xp and built the solution.

Using the original binary included in the official packages, the crash does not occur.
Any idea?

Best regards.

Thanks again for your kind help. Appreciated as always.

Best regards.

if you don’t need VS2013 anymore, why wasting GB of space - remove it
but as Vitaliy stated, both can coexist just in case you still need it.
Unfortunately VS2017 forces you to have windows account otherwise you can’t
unlock the test version and yes, the vcxproj is the one I used as well.

Cheers
Claudia

Thanks again for looking into it and solving the problem. I do appreciate it.

I understand I should be able to build NPP with VS 2017 (using notepadPlus.vcxproj and not notepadPlus.vs2013.vcxproj), correct?

VS installation is quite mammoth. :)
How would you handle it? Completely uninstalling VS 2013 (assuming I don’t need it)?

Hello Vitaliy,

Thank you for the additional info. I appreciate that.

Best regards.

1. VS 2015 and VS 2017 does support Windows XP targeting and
2. the newer VS version is used the more latest C++ features are available to the developers.

Taking this into account, as well as the availability of free Community or Express versions of latest VS, there is no much sense in staying on VS 2013 - plus, VS 2013 and VS 2015 or newer can co-exist under the very same system, if there is a need to still have VS 2013.

the new version uses keywords like noexcept which aren’t available for
VS versions < 2015, so we either could try to hack around by defining macros
changing source code etc… or you need to update to a newer VS.

Btw. I’m really impressed about VS2017 which works even on my old pc and
running in a virtual machine very well.

Cheers
Claudia

thx, I’m fine.

Yes,actually I was searching for _S_IREAD and _S_IEXEC
and I always add msdn if it is development related,
to the search to get the MS ones first.

But looks like there is something in addition missed.
Let’s see what the gitlog says about changes.

'Till then …

Cheers
Claudia

It’s always a pleasure to communicate with you.
I’m fine, thank you. I hope you’re as well.

Adding #include <sys/stat.h> to Common.cpp has indeed solved the errors appearing in the screenshot above.

I’m still getting the these errors.

Could you please enlighten me as to how you found <sys/stat.h>?
Did you search _S_IREAD?

Thank you for your kind help. I do appreciate it.

Hello Vitaliy,

Thank you for your reply too. Appreciated.

Best regards.

Hi Yaron,

long time not seen - how you are doing, hopefully fine.
As of MS, those should be available in <sys\stat.h>
Maybe you need to include this in VS 2013 CE explicitly.

Cheers
Claudia
