What is your SP expected to return?

You tried and that's good. You must have some confusion or seeking clarity. What is that?

It seems you want to talk to an author related to his/her article. If so, use foruk present at the bottom of the article for any discussion.

1 second polling is way too resource hogging, keep aside the time it might take to respond. Increase time for the job to check and see.

2. Smaple is a cleaner way to do it. Releasing the streamwriter object

AFAIK, you cannot. It's applications runtime configuration which would need app to be stopped to reload for any change.

Does that make a difference here? ASP.NET Core MVC - above details are related to that and should apply.

Okay, so does the typo solve it or not?

Did you debug step wise?
Sandeep Mewara 19-Jan-21 4:07am View
   
It would be difficult to trace such thing as is. Would suggest you to use tool like snoop to first assess the bindings are in place as expected. Tool: GitHub - snoopwpf/snoopwpf: Snoop - The WPF Spy Utility[^]

Once they are and INotifyPropertyChanged interface is referred, it should work out. Other alternatives to try would be to start with some textbox on the page, then in grid and so to see what is working for you and move step wise.

Thanks Carlo!

If above set of lines are throwing an error, you need to look at your template. Somewhere there is duplicate column or so which is being expected as unique.

Debug and nail the line of code and then go deep.
Sandeep Mewara 14-Jan-21 2:39am View
   
AFAIK, irrespective of method, you need to configure it in global settings and at IIS level to allow a defined length.
Sandeep Mewara 13-Jan-21 1:19am View
   
That was an example. You can put speciffic dates in that method like:

disableSpecific(datef) {
const dateRaw = [
new Date(date.getFullYear(),0,1),
new Date(date.getFullYear(),4,1)
];

return dateRaw.includes(datef.getTime());
}

I don't see an error response. 200-OK is expected one.

Okie dokie. I wanted OP to see more variation of the things because of types involved.

Sandeep Mewara 12-Jan-21 3:35am View
   
I believe so. There would be ways to configure inputs.
Sandeep Mewara 11-Jan-21 3:24am View
   
What all data you have? Just the date and no of cases each day? OR additional feautres?
Sandeep Mewara 11-Jan-21 3:20am View
   
It would depend on your expertise level for you to decide.
Sandeep Mewara 11-Jan-21 3:18am View
   
Debug and see where the error is being raised. Address that.

Can you try:File file = new File("C:/Users/josep/OneDrive/Documents/java/input.txt");

Slash removed at the end. Quick view, rest all looks okay. Assuming, access is there. Quick check would be to put the url in browser and see you get back what you seek.

You will return only if products is there or else not go into that code.

if(products){
// your current return code
return ....
}
Sandeep Mewara 12-Nov-20 2:51am View
   
Thats not the way. You gave a snippet so I updated that. clearly there is more code to what you shared. (your code wouldnt be just ul tags, there would be more.)

Please adjust the logic - you need to check for products being null. OR define a dummy/empty value.

Details about the error you see: NullReferenceException Class (System) | Microsoft Docs[^]
Quote:A NullReferenceException exception is thrown when you try to access a member on a type whose value is null
Possibly because:
1. You've forgotten to instantiate a reference type
2. You've forgotten to dimension an array before initializing it.
3. You get a null return value from a method, and then call a method on the returned type.
4. You're using an expression (for example, you're chaining a list of methods or properties together) to retrieve a value
5. You're enumerating the elements of an array that contains reference types, and your attempt to process one of the elements throws
6. Exception is thrown by a method that is passed null


When you debug, you will be able to get the exact line where the variable is NULL and error is being raised.

Here from the same link you shared tht you downloaded the files:

Installation

To install JavaCC, navigate to the download directory and type:

$ unzip javacc-7.0.9.zip
or
$ tar xvf javacc-7.0.9.tar.gz

Then place the binary javacc-7.0.9.jar in a new target/ folder, and rename to javacc.jar.

Once you have completed installation add the scripts/ directory in the JavaCC installation to your PATH. The JavaCC, JJTree, and JJDoc invocation scripts/executables reside in this directory.

What kind of constraint you have in table2 that would lead to not insertion of record because of @Id1.

When you say nothing inserted, wouldn't the query throw an error if for any reason it does not insert? I am still not clear on when there will be no error but 0 records inserted in table 2. (other then when where clause brings in 0 records which is independent of table 1)
Sandeep Mewara 4-Oct-20 4:25am View
   
2 things:
1. You validated the entire json and not just one block that JSON formatting is good. If not, would suggest use any online tool to quickly see if the entire json is a valid json. (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwi30fuqwZrsAhWD7HMBHVNMBRkQFjAAegQIAhAC&url=https%3A%2F%2Fjsonlint.com%2F&usg=AOvVaw1wm0AnA86fJrIoZRGRzp6P)
2. It would help if you share the exact error you get and any stack trace for reference.
Sandeep Mewara 4-Oct-20 3:25am View
   
Under what circumstance you see that insert in table 2 would fail?
Only if smething foes wrong, and if so your try-catch would trigger in.

So, only valid way how nothing gets inserted is no record selected for insert in table2 which is independent of first step. I can provide sample sql of asked flow and sequence but I don't see why you need to follow this sequence to decide commit/rollback
Sandeep Mewara 3-Oct-20 18:02pm View
   
if 0 records are inserted into table2 => keeping error case aside, wouldn't this be just when where clause do not bring any data?
INSERT INTO table2 (Id1, @Id)
			select @Id1,@Id from table3
			where table3.BBId = @BBId AND table3.Flag= 0 and 
                        table3.Id1 = @Id1

Above SQL where clause has no dependency on table1, why wait for table 1 insertion? Right?

Would suggest you read and understand about topic. It's clear you got this code from somewhere and have no idea how it does what it does.

start from something like: https://books.trinket.io/thinkjava/appendix-b.html

If you debug, I believe $stmt is not setup correct. And thus the error for execute(). Would suggest to look from there. I am not sure where you have done conn setup but that is where I will look.

@OriginalGriff explains like below:

You have tried to use a variable, property, or a method return value but it contains null - which means that there is no instance of a class in the variable.
It's a bit like a pocket: you have a pocket in your shirt, which you use to hold a pen. If you reach into the pocket and find there isn't a pen there, you can't sign your name on a piece of paper - and you will get very funny looks if you try! The empty pocket is giving you a null value (no pen here!) so you can't do anything that you would normally do once you retrieved your pen. Why is it empty? That's the question - it may be that you forgot to pick up your pen when you left the house this morning, or possibly you left the pen in the pocket of yesterdays shirt when you took it off last night.

We can't tell, because we weren't there, and even more importantly, we can't even see your shirt, much less what is in the pocket!

Back to computers, and you have done the same thing, somehow - and we can't see your code, much less run it and find out what contains null when it shouldn't.
But you can - and your IDE will help you here. Run your program in the debugger and when it fails, VS will show you the line it found the problem on. You can then start looking at the various parts of it to see what value is null and start looking back through your code to find out why. So put a breakpoint at the beginning of the method containing the error line, and run your program from the start again. This time, VS will stop before the error, and let you examine what is going on by stepping through the code looking at your values.

But we can't do that - we can't run your code, we don't know how to use it if we did have it, we don't have your data. So try it - and see how much information you can find out!

so as you type and text length grows, you will grow your textbox and form accordingly?
If so, its not a good practice to play with form window like this with your text typing.

instead try multi-line text in fixed form. It can have a scroll once length of text exceed text view.

So, I didn't knew what Laravel was. Googled it. Could it be that you need to refer the variable as:
${{course.category.name}}

i.e.: use {{ }}
Sandeep Mewara 2-Oct-20 3:35am View
   
But based on the error, category is mostly null I think.
Sandeep Mewara 2-Oct-20 3:00am View
   
You need to share the code that populates course and has it's structure.

What do you mean you don't have DBContext? Read this: https://docs.microsoft.com/en-us/ef/ef6/fundamentals/working-with-dbcontext
Sandeep Mewara 1-Oct-20 11:05am View
   
OP is looking for the table name corresponding to entities. He wrote database instead of table in original post but later in comment said: "I just want to show Physical Table Name of current model."

I am confused on what he means he doesn't have a model for DBContext given he is working on ASP.NET MVC.
Sandeep Mewara 1-Oct-20 6:08am View
   
Not to sure what you are looking for, is it:
foreach (var entityType in dbContext.Model.GetEntityTypes())
{
    var tableName = entityType.GetTableName();
    foreach (var propertyType in entityType.GetProperties())
    {
        var columnName = propertyType.GetColumnName();
    }
}

MVC follows Model-View-Controller.

ViewModel comes in MVVM.

You have tagged MVC, how is Viewmodel in picture here?

What is the difference or why are you not able to apply the same logic to another table?

Possibly yes. That would be simplest way to see. otherwise, check when all the last autoupdate happened and if those were the time when issue occured.

what is x, j? either define them or use the fields available. you cannot just use a raw code there. You need to read and learn about formula fields in crystal reports. Try with small examples and learn.
Sandeep Mewara 29-Sep-20 17:28pm View
   
In your formula field, you can write if code based on the fields available. @ShipDays is example. Use your field in the logic to set something when empty.
Sandeep Mewara 29-Sep-20 17:10pm View
   
In the formula field where you want to display data.

I mean - currently you map CustomerInvoice with 1 product in the data model. BUT, you need one to many. So, you need to change from one to a list there first and then work accordingly.
Sandeep Mewara 28-Sep-20 6:56am View
   
And the issue is?
Sandeep Mewara 28-Sep-20 6:54am View
   
Config() is not defined in the references JS. surely something is missing as a connect.

Check with developer tools to see if the JS and function is there for the page to use.
Sandeep Mewara 28-Sep-20 6:50am View
   
Then you need to change your class:
Your customerinvoice need to have:
public List<product> Products { get; set; }

You should use 'Improve Question' option above to edit/update your query.
Sandeep Mewara 27-Sep-20 8:56am View
   
No. There is nothing around compatibility here.

And you are wrong about not needing script tag. Based on what you share, you need to make sure that current page has the main.s file reference via script tag.
like:
<script src="myscripts.js"></script> //make sure to have the right relative path here
Sandeep Mewara 27-Sep-20 4:56am View
   
I can assume and reply but it would better if you share details of your Invoice, Products, CustomerInvoice class to understand how you have set them up. Use 'Improve Question' option to edit and update.

As Richard shared, it's same as any SQLite Db. Though this would mean you need to know details of the DB schema if you want some speific task with that data.

In case it can be any SQLlite db, then maximum you can retrieve tables in it and columns in it. Then some UI to select tables or columns to retrieve data.
Sandeep Mewara 25-Sep-20 9:11am View
   
I believe it should have worked. When you try it does not?

Also, if there is countable param scenario, like 3 flows - have three paramters and make use of the needed one on refresh?
these params has static values in design.

If it's organization, you have specific internal network, you have domain, why no authentication? Use active directory based windows authentication.

You need to share the code, specifically the line raising the error.

Or else the answer to your query is already shared: "This can happen when a component calls setState inside useEffect, but useEffect either doesn't have a dependency array, or one of the dependencies changes on every render."
