I created a vb.net app
In the form 2 text box and one button
Textbox1 displays current system time and textbox2, 1 hour later.
So when i press the button , sound should play exactly after 1 hour of time i pressed button.
So if I press button for 5 different time in half an hour, the sound should play after 1 hour starting from that button press.
I have following code to play sound and to display two different time in text box.
Private Sub ESREntry_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim mytime As System.DateTime
Dim hours As Double = 1
mytime = Now.ToShortTimeString
StartTimetxt.Text = mytime
EndTimeTxt.Text = mytime.AddHours(+hours)
Timer1.Start()
End sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim hours As Double = 1
Me.StartTimetxt.Text = TimeOfDay
Me.EndTimeTxt.Text = TimeOfDay.AddHours(+hours).ToShortTimeString
End Sub
I used this code for this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Console.Beep()
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Console.Beep()
End Sub

I am trying to create a program which:
Downloads a web page on a regular interval (every 10 minutes)
Finds a specific element on the page (an HTML div element with an ID of rekto)
Checks the value of that element, and then acts on it (if it's 0, do nothing and wait for the next cycle, and it if it's 1, launch notepad.exe)
Here's the code I have so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("https://controlry.tr.gg/control.htm")
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'Me.Hide()
Timer1.Enabled = False
WebBrowser1.Refresh()
WebBrowser1.Document.GetElementById("rekto").GetAttribute("value")
If
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Enabled = True
End Sub
In my application i have a label that displays the current time in HH:mm:ss
How can i get the label to update its content each second so that the time actually is correct?
Add a Timer to your project. Set the Interval property to 1000. Then...
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Label1.Text = 'Your code
End Sub
Example i press start time and the time connected in textbox that it will show when i start the time same with out time,and when i press save it wont add to datagridview. Please help me with my problem. This is my save code:
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
Table1BindingSource.AddNew()
Me.Validate()
Me.Table1BindingSource.EndEdit()
Me.Table1TableAdapter.Update(Me.OpenDataSet.Table1)
End Sub
Ok, I solved your problem....
Here is how your form should look like :
And now you need to add the "Time" columns to the datagridview:
And now... follow my steps through the image:
and here is the code :
Public Class Form1
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
Table1BindingSource.Rows.Add()
Table1BindingSource.Rows(Table1BindingSource.Rows.Count - 1).Cells(0).Value = TextBox1.Text & Table1BindingSource.Rows.Count
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CountTimer.Tick
TextBox1.Text += 1
End Sub
End Class
I Hope My Answer Was Useful To You :)
Hi so im playing with microsoft visual studio 2010 edition and I need to make an if statement work on it.
What im doing is putting a number into a textbox, it then goes into my listbox (however many times I put numbers in like 3-4 numbers). Then it is meant to add them all up and put it into the label after.
Heres the program so far
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim Result As Integer
For Each Item As Integer In ListBox1.Items
Result = Result + Item
Next
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Value As String
Value = TextBox1.Text
ListBox1.Items.Add(Value)
End Sub
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
Label1.Text = "You have a Balance of " + DialogResult.ToString
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
End Sub
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
If (String.a
End Sub
End Class
In Visual Basic .NET (which is what your code looks to be in), If statements are formatted like this:
If condition Then
DoSomeCodeHere()
End If
C# code is formatted as
if (condition)
{
DoSomeCodeHere();
}
Do you mean you wan the sum all the amount in the list box and show it in a label after clicking button 2?
If yes add the below should do.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim Result As Integer
For Each Item As Integer In ListBox1.Items
Result = Result + Item
Next
Label1.Text = "You have a Balance of " + Result.ToString
End Sub
My goal is to make code that will beep randomly anywhere from 1 to 30 seconds apart. Here is my code so far:
Public Class Form1
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Console.Beep()
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Timer1.Stop()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
End Sub
End Class
This beeps every one second. Now, I want to change the Timer Interval so that it will beep randomly between 1 and 30 seconds. Maybe later I will add options for the user to define the bounds, but for now, 1 and 30 are good numbers. I just don't know how to apply a random number to my Timer Interval.
Change the Interval on every Tick:
Public Class Form1
Private p_oRandom As Random
Private Const INTERVAL_MIN_SEC As Integer = 1
Private Const INTERVAL_MAX_SEC As Integer = 30
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
p_oRandom = New Random
End Sub
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles _
Timer1.Tick
Console.Beep()
Timer1.Interval = p_oRandom.Next(INTERVAL_MIN_SEC, INTERVAL_MAX_SEC) * 1000
End Sub
End Class
