Common.Utility | Various helper class | Document Editor library

I've created a library in an attempt to handle all of the "quirks" of using Crystal Reports in a Visual Studio (VB.NET) project. I've pulled together all the elements that have presented challenges to me in the past - setting/updating parameter and formula values, printing (including page ranges), and setting logon credentials - and put them into reusable methods that all seem to work well when I generate the reports individually.

However, I've run into a scenario where I want to reuse the same report object in a loop to print multiple variations with different data sets/parameter(s) so that I can "easily" reuse the same printer settings and other options without re-prompting the user for each iteration. In this case, I'm working with an internally built DataSet object (built by someone other than me) and my Crystal Report file's Data Source is pointing to the .xsd file for structure.

EDIT: Forgot to mention that the report was created in CR Developer v11.5.12.1838 and the VB.NET library project is targetting the 4.7.2 .NET framework and using the v13.0.3500.0 (runtime v2.0.50727) of the Crystal libraries.

My intent is/was to instantiate a new report object outside the loop, then just re-set and refresh the report's data source and parameter values on each iteration of the loop. Unfortunately, it seems that if I do it this way, the report won't correctly pick up either the parameter values, the updated data source, or both. I've been trying several variations of code placement (because I know that the order in which things are done is very important to the Crystal Reports engine), but none of it seems to work the way I believe it should.

If I instantiate a new report object inside the loop, it will correctly generate the reports for each iteration with the correct data source and parameter values. Of course, it resets all of the internal properties of my class to "default", which kinda defeats the purpose. (Yes, I know I could pass additional/other parameters to a constructor to achieve the effect, but that seems an extremely "brute-force" solution, and I'd much rather get it to work the way I have in mind).

Here is a pared-down/obfuscated version of the most recent iteration of the calling method (currently a part of a button click event handler). Every attempt I've made to instantiate a reusable object seems to result in some sort of failure. In this version, it loads the report and correctly passes along the parameter value, but the data source is completely empty resulting in a blank report. In other variations (I've discarded that code now), when I actually try to print/export/show the report, it fails with a COM exception: Missing parameter values.

I've tried using the .Refresh and .ReportClientDocument.VerifyDatabase methods separately, but those don't make a difference. When I check the parameters at runtime, it appears that the CR parameter/value and query results have been populated, but any method that makes any changes after the initialization just seems to "break" the report.

I am having trouble building in Android Studio. This is the error: Error: Program type already present: common.utility.EEG

I attempted the solutions for similar problems however I could not get it to work. I tried to look for common.utility.EEG but could not find it.

I am using JDK 12, Spring Boot 2.1.5.RELEASE , Spring Data JPA. I follow guide at https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.query-methods.sorting

I'm working on a Winforms app that executes SQL Procedures through a SignalR client. I'm relatively new to using SignalR and am still wrapping my head around it.

I start off by running my connection method to establish a connection with my SignalR service. I have two addresses configured ready for when I puslish but the DEV configuration leads to the SignalR service I am hosting locally.

I have created an Interface in a common class. I have call the inteface function in Activity.I want to implement the interface method in fragment.

this is the inteface in Utility.java
