QUESTION
I was reading this code (source):
...ANSWER
Answered 2021-Jun-16 at 02:16The n2 - n1 in the case of a negative number as a result when converted to bool will yield true. So n1 turns out to be less than n2. That's why it is a bad practice to use ints in such Boolean context.
Yes, as stated in the documentation:
...comparison function object which returns true if the first argument is less than the second
But the implementation of the comparison here leads to failure. Try this and see for yourself:

The following code does everything I want: pulls email, saves attachments, extracts files EXCEPT save the original email to the folder fDest. I seem unable to see the solution.
This seems to be the problematic line as it won't save the email: "mi.SaveAs fDest2, olMSG"
...ANSWER
Answered 2021-Jun-15 at 19:38You must be sure there are no invalid characters in the filename. See What characters are forbidden in Windows and Linux directory names? for more information. So, I'd suggest using the Replace method available in VBA before passing anything to the SaveAs method.
Another point is that you need to specify unique file names to each email. Make sure the generated file name is unique for a folder.

QUESTION
I created an empty asp.net core web application (dotnet new web -n ) and went to the github for IdentityServer4.Quickstart.UI and was followed the instructions to add the quickstart UI. I first did the powershell cmd iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/IdentityServer/IdentityServer4.Quickstart.UI/main/getmain.ps1')) to download the files and run the application but it keeps telling me Index not found but the file is inside of the Views folder. So I then deleted all those files it downloaded from the project and installed it using its templates by running the cmds dotnet new -i identityserver4.templates then dotnet new is4ui --force which downloaded those files again onto my project. However, it keeps telling me the same message.
I noticed that under the Quickstart folder, contains a folder named Home which has the HomeController.cs and the namespace is as IdentityServerHost.Quickstart.UI... do I need to change that namespace to match my solution i.e. ids.Quickstart.Home?
What is causing this to display that error when infact there is the Index.cshtml file inside of the Views folder?**
This is my startup.cs file:

QUESTION
I have a WPF app, linked to a SQL-server. I am using the MVVM-light package (I do actually have Prism.Core installed, but I'm not sure if I'm using it or not.... new to MVVM).
There's a DataGrid, bound to an ObservableCollection.
I have been trying to implement the PropertyChangedEventHandler, but I can't seem to get it to work.
I have a Delete button bound, and I am able to remove rows, but when I re-open the form, the changes does not carry over.
I tried to change the binding-mode for the DataGrid from OneWay to TwoWay. With OneWay, the changes does not carry over when I re-open the form. With TwoWay, I get this error message when opening the child form (which contains the DataGrid):
System.InvalidOperationException: 'A TwoWay or OneWayToSource binding cannot work on the read->only property 'licenseHolders' of type 'Ridel.Hub.ViewModel.LicenseHoldersViewModel'.'
So, If I then add a set; to my public ObservableCollection licenseHolders { get; },
the program runs, but the previous problem persists, like it did when there was a OneWay mode configuration on the DataGrid.
What do I need to do to get this to work without communicating directly with the Sql-server, which would defy the whole point of using this methodology in the first place?
ANSWER
Answered 2021-Jun-15 at 13:26You are confusing topics. The VM needs InotifyPropertyChanged events, which you have but are not using, to notify the Xaml in the front-end that a VMs property has changed and to bind to the new data reference.
This is needed for Lists or ObservableCollections. Once that is done, the ObservableCollection will then send notifications on changes to the list as items are added or removed.
Because you miss the first step:
QUESTION
I need to find the intersection of two arrays and print out the number of elements in the intersection of the two arrays. I must also account for any duplicate elements in both the arrays. So, I decide to take care of the duplicate elements by converting the two arrays into sets and then take the intersection of both the sets. However, I encounter a segmentation fault when I run my code. I'm not sure where this occurs, any way to fix this?

You need a vector with some space. Change vector v; to vector v(n+m);
