I added the pre tag in which you can paste your current CSS code. Please use the green "Improve question" widget.

What don't you understand in that? Right now, this just looks like you asking us to do your homework.

If no row is selected, selected index will equal -1. With the code I wrote, no button will be enabled then. You can change the logic to make it whatever you find appropriate.
And, yes, basically I think you do not need inc and maxRows class variables.

Well, explaining all of it may take quite an amount of time, and goes far beyond the purpose of a quick answers forum. If you could use the green "Improve Question" button, and qualify your question with the relevant part of the code that you have so far, then it would be easier to provide a concrete solution.
If you really are a total beginner, I would advise to put your current project on hold, and invest some time in learning the basics of the language first. It wouldn't be a waste of time, but instead will make your learning curve much smoother, in the long term.

I updated my comment. It is completely possible to do that, with any database system. As I told in the comment, you should escape the double-quotes inside the string.
phil.o 31-May-20 5:06am View
   
Try
string DataLoad = "SELECT Format([Date], \"mm/yyyy\") AS \"Month/Year\", Count([Name]) AS \"Count\" FROM [customer] GROUP BY Format([Date], \"mm/yyyy\")";

You have to escape double quotes inside the string itself.

So, you are using access database, but have tagged your question MySQL.

If the last line is not an empty line, you may be off by one (I'm not sure, though; this would need to be checked). In this case, this might overcome the issue:
awk 'BEGIN {sum=0} {sum+=length($0)} END {print sum+NR-1}'

The text of the macro as shown in my snippet is just an example. You have to modify it with the text of your own macro. file1 holds the path of the word document you want to write to, and file2 is only here because there was the need of its value in the example. You may not need the file2 variable.
And, if you have some code to share, please use the green "Improve Question" widget, and put it in the "What I have tried" section, using pre tag for code formatting.

    Dim script = String.Format("Sub MacroTest() " & _
"Const path1 As String = ""{0}"" " & _

Yes: someone apparently managed to stole some informations about you. I would have a thourough check on my computer, if I were in the same situation. Maybe you have some sort of spyware. Or maybe it is just that you are using the same password on different places, and that one of them has been stolen. There is no way for us to tell for sure from where this comes. You should also change your existing passwords, and use a different one on each site. Password manager applications exist to help you with that. Anyway, you should consider any activity on your computer as highly risky until you have had it checked free from any malware/keylogger/spyware.
phil.o 28-May-20 20:08pm View
   
No, you should either create a parameterless constructor in the Task class, so that your existing code finds this constructor. Or modify the line Task newTask = new Task(); to Task newTask = new Task(DateTime.MinValue, PriorityType.NotUrgent, "Default task"); (for example) so that it calls the already existing constructor.

You could start by clicking on the numerous links at the right side of this page which relate to this issue :)
phil.o 28-May-20 18:46pm View
   
You're welcome. You could try two things: first, explicitly declaring the Task class as public. Second: giving it a parameterless constructor, which assigns default values for date, priority and description; or use in the calling code the existing constructor (the one with parameters).
Edit: as there already exists a Task class in the System.Threading.Tasks namespace, you should give your own class another name; or, if you want to keep that name, then use the fully qualified name (FriendlyReminder.Task) in every file where the System.Threading.Tasks namespace has been imported.
phil.o 28-May-20 18:42pm View
   
Please delete this answer; the place for this is in the question, like you already did :)
phil.o 28-May-20 17:38pm View
   
I don't know. System.Threading.Tasks.Task class does not have any empty constructor (a constructor without any argument). But then, you wouldn't get the error message you actually get (it would rather be something along "No constructor accepting zero argument is defined").
What is this task class you are using exactly? Did you create it yourself? If so, could you please use the green "Improve Question" button and provide the definition of this class?
Edit: the error message suggests that Task would rather be a property, but then you would get a compilation error since the Task class would appear non-existent. None of this makes really sense.

That puzzled me too, what I proposed is just a long, long shot. Under this form, I guess the AddXY(Object, Object[]) overload will be used.

In this case, you have to count whitespaces in the function determining how many 'special' characters there are.
phil.o 28-May-20 11:51am View
   
I wondered why, too. But, who knows... :)
phil.o 28-May-20 11:38am View
   
I cannot see why $, %, ^, &, etc. would be special; they are all representable glyphs. So is whitespace, even if this glyph actually is blank.
So, what exactly is your definition of special? Do you mean a character which is not a letter nor a digit? A whitespace is not a letter nor a digit, but it is printable.
phil.o 28-May-20 10:40am View
   
The requirement is not totally clear to me. Besides, it goes beyond your original question. Please, try to do it by yourself first, then ask a new question about this new requirement if you are stuck, eventually. Sorry, but I won't write it all for you.

This is not an answer. Besides, solution 2 already explains in clear words what the core of your issue is.
phil.o 28-May-20 8:54am View
   
This is the same as what you have tried and which was not correct.
The only decent way is to use a parameterized query:
using (SqlCommand Cmd = ...)
{
   Cmd.CommandText = "SELECT * FROM Table1 WHERE Field1 = @value";
   Cmd.Parameters.Add("@value", SqlDbType.NVarChar).Value = TextBox1.Text;
   // Then execute the command.
}

The Next function, when called with two parameters, will return an integer greater than or equal to the first parameter, and strictly lower than second parameter. Thus, it will return a value between 0 and 255 (inclusive). If this value is greater than 127, we choose white (255); otherwise, we choose black (0).

Your only option is to debug your code and investigate the value of the variable holding the server name.
phil.o 28-May-20 6:48am View
   
No, because there is no obvious reason for not using a boolean type when it actually exists :)
phil.o 28-May-20 6:05am View
   
Then debug your code to see where is the issue.
The python debugger

I do not understand why you don't return True or False from your function. Python has a boolean type, so why no using it?
status = True  # instead of status = 1
status = False # instead of status = 0
return status  # instead of return (int)status

This is a common non-issue. You should not care that your ids in the database are not contiguous. They are not meant to make your data pretty, they are meant to index a row unambiguously. Strict continuity of numeric ids is nothing else than cosmetic.

The problem isn't in the setup. It is in your code relying on a file which it is expecting to find in the Program Files folder. Change the code so that this file is placed in one of the directories I told, and you will get rid of the issue.

public Counter(int _val, int _min, int _max)
{
   min = _min;
   max = _max;
   Value = _val;
}

OG means that: since setting the Value property internally calls the InRange() method, then you have to set minimum and maximum values before setting the value itself; otherwise, both minimum and maximum will equal zero, and your constructor won't accept any other value than zero.

In addition, you should have a look at what is debugging; it would allow you to have a better understanding of what your code is doing by investigating its state step-by-step.

System.Windows.Media.Brushes is not a collection, i.e. it does not implement basic collection interfaces. In this case, you'd better create your own collection.

What is in the file is one thing; but this is what is exacly in the date variable which matters.
Tutorial: Learn to debug C# code using Visual Studio
Put a breakpoint on the line string date = columns[0];, and start a debug session (F5). When the program will get to the breakpoint, its execution will pause, and you'll be able to execute it line by line (F11) and watch for the values held in variables.

You add a double value to the list. Only when you present the data to the end user, then the string representation becomes relevant. You seem to still think that 1.1 and 1.10 are two distinct values; they are not.

This will give you plenty of material on how to connect to an access database from C#. Teaching you this sort of thing is way beyond the purpose of a quick answers forum.
Please note that you cannot read from and write to a database at the same time. You can read from it with a SELECT command, and you can write to it with an INSERT or UPDATE command, for example.

The purpose of your assignment is not to test your ability to find some code on the internet and copy/paste it as your own work, but rather to teach you how to analyze a problem, draw a diagram of the required steps to solve it, and translate that into actual C code.

You will only learn how to copy/paste if we do your assignment for you. For now, your question rather looks like a "please do my homework" type of question.

Thanks for your vote.
I learnt basic in the early eighties from the language guide of my computer, a Texas Intruments TI99-4A. This guide was only describing formal grammar and syntax, with a few examples, but was nowhere near an exhaustive recipe about any requirement that a human being could even think of. I bought specialized press to get more detailed examples of what can be done and how.
The older guy you are talking about may suffer from the "It was way better before" syndrom.
I don't get what you mean by "these videos", "with strings". Which videos? What strings?
I would also add that the language is not the only thing to study: generic algorithmic, data structures, diagrams, are also quite important to learn, and they are not bound to any specific language.

The error suggests that it is in an ASP.NET project, so this has nothing to do with Unity. Moreover, this has been asked and marked as answered more than four years ago.

Whatever you will do, client side code will always be vulnerable to alteration by the client. The only place where you should handle what is possible and what is not based on user rights is on the server side.

You are aware that this code will be executed on server side, and thus will give information about server's interface, not client's one, right? Plus, this is basically a duplicate of solution 2.

You're right. I upvoted your solution as it better fits the question.

You have to iterate the array, counting whatever you have to count in the process. Read your course carefully, it contains invaluable material regarding your exercise.

Here are a couple of links to get you started with debugging:
Tutorial: Learn to debug Visual Basic code using Visual Studio
Breakpoints and Debugging Tools
Knowing how to debug is an essential skill; it allows to investigate your code to see why it does not produce the results you are expecting.
phil.o 3-May-20 7:40am View
   
Then you should begin using the debugger and watch for the contents of the elements list. Do you need help on how to conduct a debug session?
phil.o 3-May-20 7:25am View
   
Weird, because elements.ToArray() will return a String() (a string array), which is inherently an Object() (an object array).
phil.o 3-May-20 7:10am View
   
Corrected. You will need to import System.Linq namespace for the ToArray() method.
phil.o 3-May-20 7:01am View
   
Then maybe try
combo.Items.AddRange(elements.ToArray())
instead.
phil.o 3-May-20 7:00am View
   
That's why the search page I gave a link for will give you plenty of sources to get what you need done.
phil.o 3-May-20 6:49am View
   
It selects only the first one because that is what you ask for with your i variable, which is initialized to zero (the first item), and is incremented outside the loop: your loop won't ever see another value for i than zero. If you want an index-based access, then don't use a ForEach loop, but a plain For loop instead:
Dim selectedCategory As XmlNodeList = feedDoc.SelectNodes("category/" + category)
Dim elements As New List(Of String)
For i As Integer = 0 To selectedCategory.Count - 1
   Dim feedLink As XmlNode = selectedCategory.ItemOf(i)
   If feedLink IsNot Nothing Then
      elements.Add(feedLink.InnerText)
   End If
Next
combo.DataSource = elements
phil.o 3-May-20 5:25am View
   
My bad; try
Dim doc As New XmlDocument()
doc.Load("path\to\your\xml\file")
instead.
phil.o 2-May-20 18:14pm View

while (FALSE) maybe?

I wrote XmlDocument, you wrote XDocument. Those are distinct objects whose usages are also distinct.

Put a breakpoint at the beginning of the button click handler, and start a debug session (F5 in Visual Studio). Then carefully execute line-by-line, and watch for the values of variables along the way. This will allow you to pinpoint the issue. We cannot do that for you, since it needs the exact code as well as the actual data.
phil.o 2-May-20 8:25am View
   
You may have to add a reference to System.Xml.dll.
The Load method really exists:
XmlDocument.Load Method

You should never store as string a value for which there exists an appropriate type.
phil.o 2-May-20 7:34am View
   
Are you storing the wallet value as a string in your database?
phil.o 1-May-20 13:01pm View
   
I've been wondering, just waiting for some basic feedback to spot the obvious, if needed :)
phil.o 1-May-20 9:22am View
   
It means that one of the column has not been provided any value, and thus is null.
As a side note, please do NOT use Convert class to handle valuetype's parsing; use DateTime.TryParse() method instead.
if (!DateTime.TryParse(dataGridView2.CurrentRow.Cells["LasttDate"].Value, out DateTime lastDate))
{
   // Problem: lastDate could not be properly parsed. You have to decide what to do in that case.
   // ...
}
if (!DateTime.TryParse(dataGridView2.CurrentRow.Cells["TodayDate"].Value, out DateTime todayDate))
{
   // Problem: todayDate could not be properly parsed. You have to decide what to do in that case.
   // ...
}
int remaining = (lastDate - todayDate).Days;
phil.o 1-May-20 8:49am View
   
Thanks :) I wondered the same, but we can just ammend the answer if strings were used instead of proper datatype.

You're welcome! Your code does not look messy at all. On the contrary, it is quite clear for a rookie's one.

If I had to give another advise, that would be to avoid using AddWithValue method. Better use Add() method[^] instead; this allows to clearly specify the database type you are working with (and prevents some issues with string fields between unicode and non-unicode fields). Applied to your code, this would give:
command.Parameters.Add("@FullName", SqlDbType.NVarChar).Value = txtFullNameJudge.Text
command.Parameters.Add("@Contact", SqlDbType.NVarChar).Value = txtContactJudge.Text
command.Parameters.Add("@UserName", SqlDbType.NVarChar).Value = txtUserNameJudge.Text
command.Parameters.Add("@Password", SqlDbType.NVarChar).Value = txtPasswordJudge.Text

Note that you may have to correct the SqlDbType value according to your database schema.
As to how to write code efficiently, this is the kind of question which is impossible to answer in a Quick Answers question, let alone a comment. Experience is what will bring most answers to it, and remaining curious and always be able to question one's own practices are key elements, too. Wandering through CodeProject and reading questions, answers and comments can help, too.

Please, when you have a question, put it in a single place. You asked this in three other forums, two of them being the wrong place (Java and Visual Studio). Duplicating the same question all over the site will not help you to get better/quicker answers.

You did not ask any question; your generic help request looks more like a demand that we do your homework.

Your "question" is inapropriate on this forum for several reasons. First, this has nothing to do with software development. Second, we strongly disaprove malicious activities; we are a community of software developpers, so what makes you think we would help you cracking softwares? Third, this strongly smells like a very clumsy spam-attempt.

I fully agree with you on this Maciej; not knowing which culture the OP is actually using, I just assumed the invariant culture, for which the floating format does not have any thousand separator.
