Hi, I have a question, how can I achieve this, like I have declared 3 variable as string, each checkbox has a variable that will be created if clicked also when checked it will put the corresponding textbox.text into it. Now the problem is I need to make sure that the first one that will be selected will be the first one that will be paste thanks to the variable, the seond checked and third checked same thing. This is the code

 Private Sub CheckBox2_CheckedChanged(sender As Object, e As EventArgs) Handles CheckBox2.CheckedChanged
        Dim fntext As String
        Dim artext As String
        Dim dltext As String
        If CheckBox3.Checked = True Then
            fntext = TextBox1.Text
        ElseIf CheckBox4.Checked Then
            artext = TextBox4.Text
        ElseIf CheckBox5.Checked Then
            dltext = TextBox6.Text
        End If
    End Sub
    TextBox7.Text += fntext & vbCrLf & artext & vbCrLf & dltext
End Class

Hi, I have a issues, I have to load again the listbox, after filtering trought a textbox if a string is the same. I tried this code, but doesn't work at the is null or empthy, how can I reload it by a cicle for?

 Private Sub TextBox3_TextChanged(sender As Object, e As EventArgs) Handles TextBox3.TextChanged
        Dim items = From it In ListBox1.Items.Cast(Of Object)()
                    Where it.ToString().IndexOf(TextBox3.Text, StringComparison.CurrentCultureIgnoreCase) >= 0
        Dim matchingItemList As List(Of Object) = items.ToList()
        ListBox1.BeginUpdate()
        ListBox1.Items.Clear()
        For Each item In matchingItemList
            ListBox1.Items.Add(item)
        Next
        If String.IsNullOrEmpty(TextBox3.Text) Then
            ListBox1.Items.AddRange(My.Settings.userlist.ToString)
        End If
        ListBox1.EndUpdate()
    End Sub

Hello.

I want to start studying the Golang language but I can't find any IDE that I can configure well, can you tell me an IDE that is good for Go and how to configure it (explained for fools in Spanish), please? I have tried with Sublime, Visual Studio Code and Eclipse and I have not clarified with any. And, if it is not too much to ask, can you recommend a free course to start studying (if possible in Spanish)? I have found a course but I ask if anyone knows of any good and free.

I really appreciate the help.

All the best.

I'm trying to upload multiple images and I'm using longblob to store the images in database.

Hi, please advise how to resolve. I want to print the receiptno on a receipt and it prints
"receiptno". I don't know how to define "receiptno" to use the value in the table.
I'm working with mysqli and having trouble with this code:

$receiptno='receiptno';  

$sql = "UPDATE numbers SET receiptno = receiptno+1 WHERE id=1";  // ************ updates
if ($conn->query($sql) !== true) { echo "Failed to update receiptno"; }
else { echo " "; }
echo "receipt # is " .$receiptno . "<br>";

Hi all.

I have this code and it is correct.

Dim logDayName As String = WeekdayName(Weekday(LogDateTextBox.Text))
Dim logMonthName As String = MonthName(Month(LogDateTextBox.Text))

The following code is an error on the Day function.

 Dim logMonthDay As Integer = Day(LogDateTextBox.Text)

Please offer assistance. Thank you, Shane.

#include <stdio.h>
#include <math.h>

int main()

float i, x;
double fact=0, sum=0;

printf("Enter value of x as the power of e: ");
scanf("%f", &x);

printf("Enter n as the number of terms:  ");
scanf("%d",&i);    

for (i = 0; i < 99999; i++)

{   
    sum = 1 + x;
    fact = fact * i;
    sum = sum + pow(x, i)/(fact);   
}
if (sum == sum)

printf("The value of e^%f is %lf",x,sum);

return 0;

Can you please tell me what these lines of code do?

$sub_category = 0;
            if (!empty($_POST['sub_category_id'])) {
                $is_found = $db->where('type',PT_Secure($_POST['category_id']))->where('lang_key',PT_Secure($_POST['sub_category_id']))->getValue(T_LANGS,'COUNT(*)');
                if ($is_found > 0) {
                    $sub_category = PT_Secure($_POST['sub_category_id']);
                }
            }

I look forward to any assistance
