Re: C# Labels - C# Discussion Boards

Wow, you're all over the place.

What do you think this does? (Or "hope" it does).

C#

slova[i] = Convert.ToString(label[i]);

This will get long and tedious unless you do some research yourself.

I thinks it assigns label to array?

You're converting the label (object) "to a string", and assigning THAT to the array; not the label itself.

What should I do?

"What" you WANT to do is up to you; we try to help with the "how".

If you want to get the "name" of a control, then reference the ".Name" property.

Control.Name Property (System.Windows.Forms)[^]

When I click button it should start generating random numbers and every time I press button I should stop generating letters in each textbox separatly.I made it like this but when I start program and click button nothing happens.

C#

int i; 
string[] slova = new string[12]; 
Random rand = new Random(); 
private void button1_Click(object sender, EventArgs e) 
{ 
Label[] label = new Label[] { label2,label3, label4, label5, label6, label7, label8, label9, label10, label11, label12,label13 }; 
for (int i = 0; i < 12; i++) 
slova[i] = label[i].Text; 

if (!button1.Enabled) 
return; 
if (button1.Text == "Start") 
{ 
i = 0; 
timer1.Enabled = true; 
button1.Text = "Stop"; 
button1.Enabled = true; 
} 
else 
{ 
label[i].Text = slova[i]; 
i = i + 1; 
if (i == 12) 
{ 
textBox1.Enabled = true; 
button1.Enabled = false; 
button1.Text = "Start"; 
timer1.Enabled = false; 
//Vreme.Enabled = true; 
textBox1.Focus(); 
} 
} 
} 

private void timer1_Tick(object sender, EventArgs e) 
{ 
char[] letters = new char[30] { 'A', 'Б', 'В', 'Г', 'Д', 'Ђ', 'Е', 'Ж', 'З', 'И', 'Ј', 'К', 'Л', 'Љ', 'М', 'Н', 'Њ', 'О', 'П', 'Р', 'С', 'Т', 'Ћ', 'У', 'Ф', 'Х', 'Ц', 'Ч', 'Џ', 'Ш' }; 
Label[] label = new Label[] { label2,label3, label4, label5, label6, label7, label8, label9, label10, label11, label12, label13 }; 

long ascii = 0; 

ascii = rand.Next(65, 90); 
while (!(ascii != Convert.ToInt32("W") & ascii != Convert.ToInt32("X") & ascii != Convert.ToInt32("Q"))) 
{ 
ascii = rand.Next(65, 90); 
} 

label[i].Text = Convert.ToString(ascii); 
Application.DoEvents();*/ 
}

That's what "tracing" is for. Set a "break point" and start debugging. You're too needy.

I fixed all problems,program is now working!!!

C#

int i;
        string[] slova = new string[12];
        Random rand = new Random();
        private void button1_Click(object sender, EventArgs e)
        {
            timer1.Start();
            Label[] label = new Label[] { label2,label3, label4, label5, label6, label7, label8, label9, label10, label11, label12,label13 };
            for (int i = 0; i < 12; i++)
                slova[i] = label[i].Text;
 
            if (!button1.Enabled)
                return;
            if (button1.Text == "Start")
            {
                i = 0;
                timer1.Enabled = true;
                button1.Text = "Stop";
                button1.Enabled = true;
            }
            else
            {
                label[i].Text = slova[i];
                i = i + 1;
                if (i == 12)
                {
                    textBox1.Enabled = true;
                    button1.Enabled = false;
                    button1.Text = "Start";
                    timer1.Enabled = false;
                    //Vreme.Enabled = true;
                    textBox1.Focus();
                }
            }
        }
 
        private void timer1_Tick(object sender, EventArgs e)
        {
            char[] letters = new char[30] { 'A', 'Б', 'В', 'Г', 'Д', 'Ђ', 'Е', 'Ж', 'З', 'И', 'Ј', 'К', 'Л', 'Љ', 'М', 'Н', 'Њ', 'О', 'П', 'Р', 'С', 'Т', 'Ћ', 'У', 'Ф', 'Х', 'Ц', 'Ч', 'Џ', 'Ш' };
            Label[] label = new Label[] { label2,label3, label4, label5, label6, label7, label8, label9, label10, label11, label12, label13 };
 
            string randomString = "";
                randomString += letters[rand.Next(0, 30)].ToString();
                label[i].Text = randomString;
 
        }

Whether it can be made to computer take a word from database shuffle it and every time button is clicked it show letters on each textbox separatly???

Anything can be done given enough time and resources.

And you start by taking a "big" task, and breaking it down into a bunch of simple-to-understand "little" tasks, and then you tackle those one at a time; so that everyone else can understand what you are talking about.

Can you tell me what these codes does:

C#

Call rs.Open("SELECT DISTINCT Reci FROM " & CStr(duzina), Conn, adOpenKeyset)
rs.Move getRandom(0, rs.RecordCount - 1)
rec = rs.Fields(0).Value


Set rs = Conn.Execute("SELECT DISTINCT Reci FROM " & CStr(Len(r)))

They're loading "record sets" and retrieving a random record in one case.

This is "Visual Basic"; not C#.

Go to the "VB Forum".

I want to convert this codes in C#!!!

Since you don't have a clue "what" you are converting, the VB forum is the place to start. Bye.

I have the following SQL Server query:
requirements SUM and GROUP column SOLUONG AS SL , if TRAHANG = true then bring positive column opposite quantity quantity column value is negative, no team and no columns SL sum is, if I would give TRAHANG column in the SELECT statement error. Can you help me ?
[CODE]
//Query warning eror
SELECT TABHDBHCT.MAVACH_SP, TABHDBHCT.TENSP, SUM(TABHDBHCT.SOLUONG)*CASE WHEN [TRAHANG] = 0 THEN 1 ELSE -1 END AS SL
FROM TABHDBHCT INNER JOIN
TABHDBH ON TABHDBHCT.MASOPHIEU = TABHDBH.IDSOPHIEU
WHERE (TABHDBH.TTTHANHTOAN = 1 OR
TABHDBH.TTTHANHTOAN = 2) AND (TABHDBH.NGAY BETWEEN '11/01/2016' AND '11/30/2016')
GROUP BY TABHDBHCT.MAVACH_SP, TABHDBHCT.TENSP
ORDER BY TABHDBHCT.TENSP;
[/CODE]

No, because that means nothing to me.
Perhaps instead of a query that you don't explain - so we have no idea if it does what you want, or if not what it does wrong - you could give us examples of your input and what you expect as an output.
And then explain what the query does that you didn't expect or doesn't do that you did.

But most important of all is that this has nothing at all to do with C# - it's an SQL problem and shouldn't be here at all, regardless of how well or badly you try to explain it.
I'd suggest that you post here: Ask a question[^] and give sample data and a good explanation when you do.

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

It looks like you're trying to do the calculation outside the SUM aggregation but it isn't included in the GROUP BY clause.

Try something like

SQL

SELECT TABHDBHCT.MAVACH_SP, 
       TABHDBHCT.TENSP, 
       SUM(TABHDBHCT.SOLUONG * CASE WHEN [TRAHANG] = 0 THEN 1 ELSE -1 END) AS SL
...

Running OK, Thank you very much

I can't save any changes to the text file settings.txt , but reading the file works.
 The code is

 private async void LedShow_Loaded(object sender, RoutedEventArgs e)
 {
 var path = @"settings.txt";
 var folder = Windows.ApplicationModel.Package.Current.Installed Location;
 var file = await folder.GetFileAsync(path);
 var lines = await Windows.Storage.FileIO.ReadLinesAsync(file);
 sliderDelay.Value = Convert.ToInt32(lines[0]);
 textBlockDelayValue.Text = lines[0] + " seconds";
 buttonSave.IsEnabled = false;
 }

 and the error message is 

 An exception of type 'System.UnauthorizedAccessException' occurred in System.Private.CoreLib.dll but was not handled in user code
 Access is denied. (Excep_FromHResult 0x80070005) occurred
 Can someone help me?

This would be right. A program normally does not have rights to write to the Program Files folder. In order to do so, you will need to elevate the rights of the application and gain administrative privileges.
The recommendation would be to use the AppData folder. Your best option would be to try and read the file from that location, and if not there, then copy it from the program files folder. Then you can read and write the file to your heart's content.

Cheers,

Mick

Yeah, that's not going to happen. Nobody is going to do your work for you.

The entire point behind this project is to demonstrate what YOU have learned over these courses, not what begging skills you have.
