Most probably you're missing a using directly.. something like System.Collections, but I'm not really sure.
GKP1992 27-Nov-19 23:28pm View
Stop using it like that?

I like how you gave them the solution but still left some things for them to figure out.

This may be of some help.

Also, nvarchar uses 2 bytes per character whereas varchar uses 1. The direct correlation of success at 368 and failure at 767 is suggestive enough of that.

And what does the data in the error function say? Try to debug a little. Probably it has "404 not found" error.

Let college take its course. Learn well what is being taught, and you'll have a good enough idea of computer programming by the end of it. Programming cannot be learnt overnight. There's no easy (faster) way, so get ready to dive in.

What is the error you get when trying to run it? By the looks of it, this code is already in C# so you don't need to convert it to C#.

Using the DateTime class, you can use the year property of the date and assign it to your variable.

The only issue is the first one "ORA-01403". Check why you have no data and fix that, there is a good chance that a "SELECT INTO" statement that has no data to select from is breaking your job. All other errors are a result of the first one.
GKP1992 28-May-18 23:45pm View
What do you mean by the count of the current number? Do you want to know how many hits there are in the matrix or just the number which follows the condition?

Did you try writing a.outerxml as it is in the VB code rather than a.OuterXML?
GKP1992 28-May-18 3:16am View
If I simply do this,
var x = "3V 1 TP&WB;-OV 29.95";
var y = x.Split(' ');

I get "3V", "1", "TP&WB;-OV" and "29.95" in y. So, you're doing something wrong.

GKP1992 11-May-18 8:09am View
What is the problem with the one you came up with? The only thing I see is that your regex can accept "None" irrespective of the case of the letters. If you want only "NONE" specify it literally.

Read the first paragraph of the solution. I removed those columns to avoid doing just that.
GKP1992 25-Apr-18 6:54am View
Okay, I was just too lazy to do that, also I changed the structure a bit to make the query cleaner. For example, I just added a foreign key relationship between the tables and removed the repeated columns.
GKP1992 24-Apr-18 23:35pm View
Usually, you add a reference to the DLL in your project. Then you can use it.

Yes, you'll need to call the constructor for each person as you are creating a new person each time. I misread that, apologies. Yes for PersonModel creating a constructor that sets the private members for each person in GetList.

If you have so many records why don't you try server-side data grids and get new data when you change a page in the grid. I'm sure the page will load faster with fewer records to fetch.
GKP1992 2-Jan-18 4:54am View
There is no way SQL server can know which value to update out of the various values separated by commas. You have to do it programmatically and update the whole value.
e.g. Initial Value = ram, name
Logic to determine final value, takes initial value as input
Final value as output of previous logic.
use this value to update row.
update emp set emp_name = "final value" where empId = "id"

It's not really easy to explain what you have to do. Once you start doing it you'll get to know. The idea is to keep common functionalities in a single file just like for wind and temparature. I would've added another class for Weather station that holds the information about the weather station, and then a class that uses all these to measure and display the weather information. Call these functionalities from the main function. I get that it may sound confusing, so the only way is to dive in.

As PIEBALDconsult pointed out, storing dates as strings in the database is a horrible idea. I can think of only one reason why someone would have done so, is to be able to use the like clause etc, but even then it does have any advantages. It just slows down your DB server. Please use DateTime.

I think it is called a block in Oracle. Goes like this

declare {var_name} {vartype} := {value};
{write query that uses var here.}

As far as I understand, you insert the query into a table with query id as the primary key. Is that correct? Also, which version of Oracle are you using?

If you have a problem in the PasswordSignInAsync method, it is a good idea to check inside that method, see where the problem occurs and post the "problematic code" here.

Probably because you have the information of only one user in the action result method.
Do you think using a collection of user info to iterate through to assign them the random number and then saving/updating will do the trick?

Just tested my solution with trailing zeroes, it works :-D, even though I did not intend it to.
GKP1992 17-Oct-17 6:55am View
I think trimming will give a wrong result if I use my solution, 0.60 - 0.01 = 0.50, whereas 0.6 - 0.1 = 0.5. My vote of 5.
GKP1992 17-Oct-17 4:44am View
I was considering the point you make in step 3.2, but I did not go with it since a fraction with a 0 in the end, did not make sense. Since it is a user entered string, it doesn't have to.
GKP1992 17-Oct-17 2:22am View
Have you considered using sessions instead of variables?
GKP1992 16-Oct-17 23:33pm View
Yeah, I missed that you wanted to upload multiple files. In that case, the regex is not useful to you.
Also, you need to ask yourself a few questions like if you're selecting multiple files and some of them are not valid, what should happen? Should the validator accept the only valid files or should it discard all of them?
I will update the anwser.

do not see the necessity of the new variable, also to compare with 26 we have to write index <= alphabet.lenght in the for loop condition which we cannot do because alphabet[26] will break for the last comparison. Since it is index < alphabet.lenght, maximum possible value for occurencePositive is 25 (if all the letters are found). Anyways, glad it helped.

No one will help you finish your homework, but here are some hints. There are two Getpercentage methods with the same signature, this is confusing for the compiler. The methods Getpercentage, gettotalnostudents and Getpercentage do not know what are a,b,c,totalnostudents, s and t. Start with defining those variables and take it from there.

Hello digimanus,

It is not as easy as it looks but, as far as I can understand your problem, you can take advantage of Take and Range methods of the Enumerable class. Use the columnNames.Count to take the collection of labs and vars and update them using a for each.

Hope it helps.
GKP1992 5-Oct-17 5:28am View
Thanks for the details. Can you also share the table structure, I'm not sure why you need the column names in the inputFile. If they're going to be based on the number of columns in the excel file, why not update the columns sequentially using a foreach loop and update the rest with nulls?

Few questions:
1. What do you mean by resetting the code?
2. Do you mean you decompiled an assembly to get the code?
3. How do you want to use the code?
If you just want to encrypt something you can just add a reference of the assembly you decompiled to your project, and call the method you are trying to "reset" with the text you want to encrypt. Pretty straight forward. Beyond that, it is a research topic. You are on your own.

GKP1992 4-Oct-17 0:14am View
I cannot say what is the problem you face but multiple return statements in a single code flow never work. A return statement means that the execution of the code block (in this case the method) is finished and the control will exit the method, so for your grades method, after the line
return round2(weightedHomeworkScore);
nothing will be executed. You might wanna reconsider your method and think about what you want it to do.

I sympathize with you, but there is no easy way to learn something. You have to dive into it headfirst. If you do not understand what is written in the books. I suggest you find a teacher near you. It'll help you understand the basics of computer programming. Forums are only going to help you when you some understanding of the subject, since these are people who help other people voluntarily. If you do not respect that and expect them to do your homework, they are not going to like it.

I suggest you have a look at other CP questions and take some ideas for posting questions. Or read the rules. You are not making a lot of sense here. It is hard to know what you want with your code? What is the problem you face? If feels like you are very new to programming so I suggest you to take smaller steps. Importing excel data to SQL comes later. But if you wish you can take a look at SSIS solutions.
