visual is a Python library. visual has no bugs, it has no vulnerabilities and it has low support. However visual build file is not available and it has a Non-SPDX License. You can download it from GitHub.

as of early 2008, this information is obsolete. see install.txt instead. the following notes were written by jonathan brandmeyer, june 2006. this directory is a kind of sandbox that i'm using to build and test a new opengl rendering engine for vpython. dependancies (in debian): libboost-python-dev libboost-thread-dev ftgl-dev libgle3-dev libgtkglextmm1-dev (note: in debian sid, you will need to build gtkglextmm 1.2 from source, and apt-get install libgtkmm-2.4-dev) scons. notes for building: assuming you have all of the development packages that the new core expects, make sure that you edit the value of 'visual_prefix' in include/vpython-config.h to be the path to the source tree. vpython uses scons to build itself, and does not include any kind of 'install' target, yet. instead, it builds its target programs and libraries in-place in a layout similar to what you would find under /usr. directory layout sconstruct a scons build file for this project. run scons to build the python extension module. run 'scons bin/' to run the c++ tests. run a script that sets up environment variables to use the target libs and plugin. ex: './run python2.3' will place site-packages/ in sys.path. bin/ programs are built in-place here. to run any of the tests, prefix the command with the run script, like:

Why do Switch and ListView controls in MAUI not update with 2-way binding?

Asked 2022-Apr-11 at 09:33

This question is about two MAUI controls (Switch and ListView) - I'm asking about them both in the same question as I'm expecting the root cause of the problem to be the same for both controls. It's entirely possible that they're different problems that just share some common symptoms though. (CollectionView has similar issues, but other confounding factors that make it trickier to demonstrate.)

I'm using 2-way data binding in my MAUI app: changes to the data can either come directly from the user, or from a background polling task that checks whether the canonical data has been changed elsewhere. The problem I'm facing is that changes to the view model are not visually propagated to the Switch.IsToggled and ListView.SelectedItem properties, even though the controls do raise events showing that they've "noticed" the property changes. Other controls (e.g. Label and Checkbox) are visually updated, indicating that the view model notification is working fine and the UI itself is generally healthy.

Build environment: Visual Studio 2022 17.2.0 preview 2.1
App environment: Android, either emulator "Pixel 5 - API 30" or a real Pixel 6

The sample code is all below, but the fundamental question is whether this a bug somewhere in my code (do I need to "tell" the controls to update themselves for some reason?) or possibly a bug in MAUI (in which case I should presumably report it)?

Sample code

The sample code below can be added directly a "File new project" MAUI app (with a name of "MauiPlayground" to use the same namespaces), or it's all available from my demo code repo. Each example is independent of the other - you can try just one. (Then update App.cs to set MainPage to the right example.)

Both examples have a very simple situation: a control with two-way binding to a view-model, and a button that updates the view-model property (to simulate "the data has been modified elsewhere" in the real app). In both cases, the control remains unchanged visually.

Note that I've specified {Binding ..., Mode=TwoWay} in both cases, even though that's the default for those properties, just to be super-clear that that isn't the problem.

The ViewModelBase code is shared by both examples, and is simply a convenient way of raising INotifyPropertyChanged.PropertyChanged without any extra dependencies:

ViewModelBase.cs:

These both may be bugs with the currently released version of MAUI.

This bug was recently posted and there is already a fix for the Switch to address this issue.

Upgrade VS2022 preview to release version

Asked 2022-Apr-04 at 00:57

I have Visual Studio 2022 Preview installed and would like to replace it with the release version that went live yesterday.

When I started VS and checked for updates, it let me upgrade from the previous release candidate to Preview 1.0, but not the actual release version.

Is it possible at all to replace the preview with a release version, or do I have to install them side by side (and delete the preview)?

This is the version I have now: Microsoft Visual Studio Professional 2022 (64-bit) - Preview Version 17.1.0 Preview 1.0

Python/Docker ImportError: cannot import name 'json' from itsdangerous

Asked 2022-Mar-31 at 12:49

I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.

I downgraded Flask to 1.1.4 and markupsafe to 2.0.1 which solved my issue.

.NET 6.0 not showing in Visual Studio 2022 (General Release)

Asked 2022-Feb-10 at 09:47

I have installed .NET 6.0 SDK and Visual Studio 2022. However, Visual Studio 2022 does not offer the ability to select .NET 6.0.

I know I can edit the project file with the target framework so please don't suggest that. This question is specifically around the Visual Studio 2022 UI.

Edit 1:

.NET 6.0 Runtime has been selected in the Visual Studio Installer for Visual Studio 2022

During Visual Studio setup, you need to select the ".NET 6.0 Runtime". As can be seen in the screenshot, this option not only includes the runtime itself but also "templates for developing [...] .NET 6.0 applications".

You can modify your installation by starting "Apps & Features" from the Windows start menu or by selecting Tools/"Get Tools and Features..." from the Visual Studio menu bar.

Why is constexpr of std::wstring().capacity() not equal to std::wstring().capacity()?

Asked 2022-Feb-03 at 11:10

I'm not sure if I'm too naïve or simply too unknowing.

But why does the following differ?

...

ANSWER

Answered 2022-Feb-01 at 19:39

Microsoft's STL disables short string optimisation in constant evaluated contexts, so it allocates memory instead.

The allocations are always one more than a power of two, so the capacity (which excludes the last L'\0') is always a power of two.

In the non-constant-evaluated version, the short string buffer can hold 8 characters, one of which is a L'\0', so the capacity is 7.

Since C++17 the order of evaluation is specified such that the operands of = are evaluated right-to-left and those of << are evaluated left-to-right, matching the associativity of these operators. (But this doesn't apply to all operators, e.g. + and other arithmetic operators.)
