Cannot access a disposed object

I have a C++14 x64 application built with visual studio enterprise 2017 (v15.9.4)

I am trying to add an icon for my exe but when I try to add in a new resource file (Resources.rc) I get an exception from visual studio:

Cannot access a disposed object.
Object name:
`Microsoft.VisualStudio.Project.VisualC.VCProjectiEngine.VCProjectFileShim`.

and

The object has already been disposed. (Exception from HRESULT 0x80131622

I have created other projects and successfully added Resources.rc but for this particular project I am getting the above exceptions. Is there a way to fix the project file without having to recreate the project from scratch?

VS 2019 - Visual Studio Emulator for Android no longer selectable

I always had Visual Studio Emulator for Android as an emulator option in VS 2017, but my only option now is the prepackaged Android SDK emulator, which is still sluggish after all these years.

Some info:

- I reinstalled the VS emulator along with VS 2019 on a fresh windows installation

- The emulator runs fine, I just can't find a way to select it in the drop down for debug/release in VS

- I cannot seem to find any trace of the VS Emulator in VS 2019's menus like in VS 2017

- I obviously have Hyper-V enabled

Filter mode for Goto Files

Hi there somewhere a switch to configure the filtering mode when searching source code files?

I would really appreciate if the function would not try to find all characters but instead would use a substring search - separated by blanks (that is the Visual assist used to work).

Example

A search for a .proto file 

"f str .proto"

currently brings strange results like

resulto.cpp
c:\projects\sample\resulto.cpp

as all letters can be found somewhere - even the path.

I Would expect, that all non-separated strings ("str" and ".proto") yield results, if they can be found as concatenated string like

my_string.proto

That would reduce the results significantly and give a much better matching.

Is the matching mode configurable?

Thanks

Online compiler collection using various Visual C++ toolkit versions?

Dear Visual Studio experts,

are you aware of an online compiling tool where I could test some #ifdef magic aimed at supporting various MSVC toolkits? (ideally from v90 to v14x included...) ? I'd like to avoid the hassle of setting up a VM, installing tools... I just need to test a simple TU with some static tests. Compiling is enough, I do not need to link or execute (barring code generation bugs).

I know about _MSC_VER, _MSC_FULL_VER, __cplusplus , _MSVC_LANG and /Zc, but I'd like to test my feature flag detection before pushing my changes into the wild (it's indeed quite scary looking, when taking into account GCC and clang support, and I might want to add support for other compilers in the near future)

I already know about Compiler Explorer but it only goes as far as v140, and I am precisely concerned by the v90/v100 era.

Thanks in advance!

Use Android Studio's emulator for running a Xamarin Form project?

It seems that Visual Studio comes with its own Android emulator that tries to use Hyper-V. But I already have Android Studio installed which has an Android emulator, for which I have created a few AVD's that use Google's AMD hypervisor driver (sort of like Intel's HAXM, but for AMD CPU's) which do not use Hyper-V.

Is it possible to use those AVD's for running a Xamarin Form project with Visual Studio? It seems that those AVD's show up in the emulator list, but Visual Studio says Hyper-V is not installed.

appropriate use of Visual Studio Community?

Hi,

I am a medical physics student. As part of my MS program I am doing some work under the supervision a medical physicist at a nearby hospital. I have been asked to develop a database application that will be used by the hospital to validate treatment plans for radiation therapy. I am currently an "unpaid intern" at the hospital although I have been informed that I may be offered a QA job unrelated to my current research project (medical physics students wear many hats).

Is it okay to use Visual Studio Community on my personal laptop, as long as Visual Studio Professional is used on all of the hospital computers? For rhetorical purposes let's assume that the hospital IT department is byzantine and terrifying.

Thanks for your help and patience ^,~

I am writing a MFC app, in which one of the controls is HTML editor...Earlier i was using IE for editing the HTML on that control.

With Microsoft Edge chromium, i want to know how can i use it for inline HTML editing.What interfaces exist for editing HTML content.

The controls for editing(just like the the ones visible while creating this question), in my case are actual MFC controls and based on those controls and changes in edit window,  I want to have this Microsoft Edge chromium based HTML editor(existing as a control in my MFC app) to enable edits to HTML content.

The symptom is:

First-chance exception at 0x7703f9f2 (ntdll.dll) in ....exe: 0xC0000008: An invalid handle was specified.",

occurring after the Form has closed. The top of the call stack is:

ntdll.dll!_CloseHandle@4()

The project is dual native C++ and C#. I have no idea of how to determine where this bug originates. Is there a way to find out who owns the handle? Anyone have a clue?

Hello all. I'm trying to use the SIMD functionality of .NET 4.6.1 in Visual Studio 2012 (express desktop) and I'm having some trouble. I'm able to target .NET 4.6.1 in the Project Properties page, but when I right-click the project in the Solution Explorer, select "Manage Nuget packages...", search and select the "System.Numerics.vectors" package and attempt to install I get an error claiming:

"The System.Numerics.Vectors 4.1.0 package requires NuGet client version 3.0 or above, but the current NuGet version is 2.8.60318.677".

When I click the "Upgrade NuGet" button nothing seems to happen. Can someone please provide some guidance? Thank you in advance.

Work Item Queries

Hi all,

we're relying heavily on Work Items and of course created a lot of queries around it. What I would need, is a cascading query strategy and I can't get a grip on that. Figure the following:

  • Colleague A creates a query Q1 with criteriaC1 C2 and C3
  • What I would need to do now is sub-filter that very list for criteria C4
  • Today I'd create a copy of the list, add my criteria and save it as Q2
  • But now, if user A is changing his query, I never get that change as I have acopy
  • What I would need is ("Whatever is the current Q1 comes up with" plus myC4)

Is that somehow possible and I just don't see it?

Thanks in advance, Carsten
