Im going to have this objects: textbox,progress bar and button.
I need to push the button and start 1 minute, then you enter integers in the texbox and they have to be count it and sum it later when the minute ends... show how many numbers i input and the sum..
so far i understand how run a timer but how i give condition for this process, i mean i capture the numbers but how i link the time and the progress bar?
Public Class Form1
Dim recolector As Integer
Dim contador As Integer
Dim sumatoria As Integer
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles btnAgregar.Click
Try
recolector = Integer.Parse(txtNumero.Text)
Catch ex As Exception
End Try
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Timer1.Interval = 60000
While Timer1.Interval < 60000
End While
End Sub
End Class

I need to know the value of time. I mean the interval of time; from starting time to ending time. Anyone can help? :(
This is my list and I want to get the interval value of time.
When I select the item/record in the Datagridview2 it will displayed here
Can somebody share an idea/or code? Thanks
To achieve something like this, you need the TimeSpan data type.
In my example, a variable is written with the current time at the beginning of the runtime.
A timer regularly calculates the new time span between time 1 and the current time, and outputs this time span in a text box.
Also, I use CultureInfo (I always do, don't be surprised) and I use PadLeft to have leading zeros. Looks nicer.
Public Class FormMain
Private ReadOnly Starttime As Date = Date.Now
Private ReadOnly Deu As New System.Globalization.CultureInfo("de-DE")
Private Sub FormMain_Load(sender As Object, e As EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Timer1.Start()
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Dim TS As TimeSpan = Date.Now - Starttime
TextBox1.Text = TS.Minutes.ToString(Deu).PadLeft(2, "0"c) & ":" & TS.Seconds.ToString(Deu).PadLeft(2, "0"c)
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Timer1.Stop()
End Sub
End Class
the timer in my code stops working after the first tick, I have it set to start ticking every second when the form loads:
Private Sub FormIdleTimeWaster_Load(sender As Object, e As EventArgs) Handles MyBase.Load
timerCPS.Interval = 1000
timerCPS.Start()
End Sub
but after the first tick, it stops working:
Private Sub TimerCPS_Tick(sender As Object, e As EventArgs) Handles timerCPS.Tick
lblCPS.Text = CStr(CPS)
lblTotalHW.Text = CStr(CPS + HWTotal)
End Sub
All the other code refrencing timerCPS is
Me.timerCPS = New System.Windows.Forms.Timer(Me.components)
Friend WithEvents timerCPS As Timer
Nowhere else references timerCPS in my code and I'm not sure what's wrong
I have replicated your code as given in the question and it is working perfectly fine. It is ticking over every second.
I have modified your code to this:
Public Class FormIdleTimeWaster
Private CPS As Integer = 1
Private Sub timerCPS_Tick(sender As Object, e As EventArgs) Handles timerCPS.Tick
CPS += 1
lblCPS.Text = CStr(CPS)
End Sub
Private Sub FormIdleTimeWaster_Load(sender As Object, e As EventArgs) Handles MyBase.Load
timerCPS.Interval = 1000
timerCPS.Start()
End Sub
End Class
I can clearly see the value in the label increasing by one each tick.
The call to timerCPS.Start() is not needed in timerCPS_Tick.
If you still have an issue then there is some other code you haven't shown.
I would like to do a For Loop inside a timer. Since I want to check an array with element row continuously and I cant continue since the loop seems to not move from 0 on tick, is there a way around this?
I first tried this:
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
For row = 0 To 9
msgbox(row)
Next
And then I tried another approach, as suggested in an answer
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
row+=1
msgbox(row)
if row = 10 then
timer1.stop()
end if
Next
MsgBox will now output 0++ on tick but does not stop at 10.
Output Picture
Dim row As Integer = -1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
RefreshData()
Timer1.Enabled = True
initialize()
End sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
increment()
MsgBox(row)
End sub
Private Sub increment()
If row > 8 Then
row = 0
Else
row = row + 1
End If
'my if else statement for checking array variable(row)
End Sub
With this code msgbox was able to output 0 to 9 and repeat the process since i need it to continuously monitor the array. For some reason though when msgbox is situated at the first line of increment method or on timer tick before increment is called the output stays -1 the whole time dunno why. Anyways thanks for all the input as im still new to visual basic 2015
Instead of using for loop use a global variable and increment it inside the tick function
Dim ctr as integer = 0
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
ctr=ctr+1
row(ctr)
msgbox(row)
if ctr == 10 then
ctr = 0
timer1.stop
end if
How to create make an event call back every x seconds in VB.NET?
How do I make it add one to my counter every 10 seconds?
Public Class Form1
Private Counter As Integer = 0
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Label1.Text = Counter.ToString
Me.Timer1.Interval = TimeSpan.FromSeconds(10).TotalMilliseconds
Me.Timer1.Start()
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Counter = Counter + 1
Label1.Text = Counter.ToString
End Sub
End Class
I'm making a game in VB.Net and I'm not familiar with the progress bar. I need something where the player need to press a button as fast as they can to fill up the progress bar and proceed to the next leve or if not fast enough then lose.I have no code for this because I don't know how to build up something like this. Any help would be grate.
Thanks
Say you have a button, Button1, and you have a progressbar, ProgressBar1.
You can add to the progressbar's value everytime you click on Button1 by using the following code:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
If ProgressBar1.Value + 1 < ProgressBar1.Maximum Then
ProgressBar1.Value += 1
End If
End Sub
Now, notice the condition I wrapped the increment code with. This will make sure that the user does not surpass the maximum value allowed in the progressbar1.
Edit:
As for the rest of your program, you will need to use a timer in order to track the time.
for the proceed button, you will need to use the visible property which exists on buttons in order to hide a button until some condition is met.
Re-Edit:
Public Class Form1
Private intCurrentTime As Integer = 0
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
If ProgressBar1.Value + 1 < ProgressBar1.Maximum Then
ProgressBar1.Value += 1
End If
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
If intCurrentTime = 10 Then
If ProgressBar1.Value = ProgressBar1.Maximum Then
'SHOW "Proceed" BUTTON
Else
MsgBox("You have failed!")
End If
intCurrentTime = 0
Else
intCurrentTime += 1
End If
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Timer1.Start()
End Sub
End Class
