I'm learning ADO.Net and have been performing SQL commands on GridView. Today I started to learn the SqlDataReader In ADO.Net and when I try to Execute my Command and pass it to the SqlDataReader Object, it shows the error

> CS0029: Cannot Implicitly Convert 'System.Data.SqlClient.SqlDataReader' to 'AdoControls.SqlDataReader'

This is my code:

I'm trying to use the INLotSerialNbrAttribute on my custom screen. I get below error message. I think it must have something to do with some screens using the split function. For my screen I just want to allow a single Serial Number per line similar to the adjustment screen. Do I need to add something on my graph to handle this or should I create my own selector?

Here's the definition of my DAC field

The task is not practical, it's just learning experiment.

I have .net5 app (which essentially is asp .net core app) which references onto neighboring project "WebControllers" which contains only Controller class.

WebControllers is .net5 class library into which I added reference to Microsoft.AspNetCore.Mvc.Core package. This package allows to create of working Controller object which is discovered by asp .net core infrastructure and which properly handles http requests.

Now I want inside my WebController objec create variable of ApplicationPartAttribute type. I tried doing this like that:

I have a search webpage where the user can apply for jobs. The jobs are displayed through repeater control. When the user clicks on apply button I want a modal to popup with two textboxes containing the companies email and the job name.

With what I have tried I am not getting an error but the modal is not showing up. Here is my code .aspx code for repeater

I'm using Spring Security on a basic Thymeleaf setup with index.html and login.html, however the default login page always returns 403 Forbidden when the credentials are valid. (It gives a UI error when the credentials don't match, as expected).

I believe it's due to the CSRF token which is already included as a cookie (XSRF-TOKEN) in every request to backend. I'd rather not simply disable CSRF, so I've tried including this token into the POST request in almost every way I could find online:

• changing target to /login?_csrf=token
• inserting into the Thymeleaf form (this is default behaviour and I checked that it does send, but backend rejects it??)
• swapping from normal form submission to AJAX/fetch and inserting X-XSRF-TOKEN header. Doesn't work too, including both JSON and x-www-form-urlencoded encoded requests.

I am having a very weird problem that I cannot figure out. I am trying to add a loading dialog box to a page that generates a pdf. I coded the web page in a separate project, and the dialog box worked perfectly. But when I included the extremely basic jquery-ui code into my existing website project, it doesn't work. Specifically, the popup doesn't go away when the PDF loads into the iframe. Basically the .load(function()) event isn't triggering.

I am working on a legacy ASP.NET website project that utilizes a custom MembershipProvider. I want to take advantage of the existing functionality that this provides to implement password validation. I want to ensure that all future passwords are of a certain length and contain a certain number of uppercase, lowercase, and non-alphanumeric characters.
