I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

I have a div which with long content and that is why the scrollbar is coming. I want when user click on a button. Then, the div scroll bar goes to end of the content. I tried this way but no luck.

I want to achieve this without using jQuery.

I'm running boto with python3 and I'm running an ansible playbook to setup some ec2 instances. Everything is fine, creating instances, security groups, key pairs, everything in eu-west-2. When the task for Elastic IPs runs it fails with this message: Region eu-west-2 does not seem to be available for aws module boto.ec2. If the region definitely exists, you may need to upgrade boto or extend with endpoints_path

I'm running ansible with -e ansible_python_interpreter="/usr/bin/python3". I have latest boto installed.

Im trying to create a multithreaded namedpipe server as outlined in the msdn sample here https://docs.microsoft.com/en-us/windows/win32/ipc/multithreaded-pipe-server but Im trying to restrict the namedpipe to access by adminstrators group members only.

The example works correctly when no SECURITY_ATTRIBUTES structure is specified but when an SA is specified the first call is successful, but following calls to CreateNamedPipe fail as long as the first pipe is listening or communicating with a client. The create call fails, usually with ACCESS_DENIED, but sometimes with error 1305 The revision level is unknown. When the first pipe closes due to client disconnecting the following call will be successful for the next createnamedpipe call but will in turn fail once that pipe has a client.

I have tried multiple values for the grfInheritance field with no avail. This is my first adventure into explicitly specifying SECURITY so forgive me if I have missed something obvious. Note that in the Function that calls createnamedpipe I create a new SA structure with each create attempt but I have also tried creating one and sharing it outside the create loop.

Relevant code follows:

function that creates the pipe:

I have a script that gives me the days of the week, when I enter the day from 1 to 30 there are no problems, but when I enter the 31st, the script returns the first day of the same month.

The regex expression below is for finding valid Amazon Cognito IdentityPool IDs with a test file but using the same expression with grep finds no valid matches yet the regex matches the test strings on https://regextester.com Regex expression: (us(-gov)?|ap|ca|cn|eu|sa)-(central|(north|south)?(east|west)?)-\d:[0-9a-f-]+ or even simplified like [\w-]+:[0-9a-f-]+. Both fail for test strings like below yet are matched on Regextester.

I have a file filtered_content with the following content:

Without spring boot ,we must specify the detail of a data source,right?

I have a register form with next fields:

1. Name
2. Email
3. Password
4. Confirm password
5. Optional field
6. Select role( student, professor, secretary)

What I want is:

If I want to create a user with student role, optional field should not be considered, but if I want to create a professor/secretary user, then I will have to type a certain password in optional field (https://prnt.sc/159y5x9)

This is my Register function:
