So, I'm making a VB.NET software, and want to show minute format as XX minute, e.g: "05 minute left" and not like this: "5 minute left." My code now like this:
min = DateTime.Now.ToString("mm") + NumericUpDown2.Value
I've tried with big "MM" letters but it's just another time format.
Is that a countdown application, and when I'm try to check the time failed.
If Date.Time.Minutes = min Than
Alarm.show
End If
Although this code has not been tested it should give you some ideas of how to proceed. As far as the formatting is concerned - right pew, wrong church. Number.ToString("00")
Private AlarmTime As DateTime
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
AlarmTime = DateTime.Now.AddMinutes(NumericUpDown1.Value)
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Dim TimeLeft As TimeSpan = AlarmTime - DateTime.Now
Dim MinutesLeft As Integer = TimeLeft.Minutes
Label1.Text = MinutesLeft.ToString("00")
If AlarmTime >= DateTime.Now Then
Alarm.Show()
Timer1.Enabled = False
End If
End Sub
The right way to do this is like this:
DateTime.Now.Minute.ToString("00")

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
I'm trying to make a countdown timer that displays minutes. Unfortunately, when I try to run it the minutes go down way faster than they should. The timerinterval is at 1000 (1 second). How can I fix this and make it a functioning timer? I've tried many different ways to make this countdown, so any suggestions on an alternate method are alright as well. I have a different label for minutes and seconds at the moment.
Public Class Form1
Dim CurrentTime As Integer
Private Sub btnQuit_Click(sender As Object, e As EventArgs) Handles btnQuit.Click
End
End Sub
Private Sub Form1_MouseMove()
End Sub
Private Sub btnStart_Click(sender As Object, e As EventArgs) Handles btnStart.Click
tmrStart.Enabled = True
CurrentTime = 180
End Sub
Private Sub tmrStart_Tick(sender As Object, e As EventArgs) Handles tmrStart.Tick
CurrentTime = CurrentTime - 1
lblSeconds.Text = (CurrentTime / 3) * 10
If CurrentTime < 180 And CurrentTime > 120 Then
lblMinutes.Text = "2"
ElseIf CurrentTime < 120 And CurrentTime > 60 Then
lblMinutes.Text = "1"
ElseIf CurrentTime < 60 And CurrentTime > 0 Then
lblMinutes.Text = ""
End If
End Sub
Private Sub lblSeconds_Click(sender As Object, e As EventArgs) Handles lblSeconds.Click
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
CurrentTime = 180
End Sub
End Class
If you're dealing with time, then you'd be better using the Date type. If would make your code much cleaner if you declared currentTime as a date - like so ..
Dim CurrentTime As Date
Then, where you assign a value to it you would use
CurrentTime = #0:3:0#
-- 3 minutes ..
Then change the following subs to these
Private Sub btnStart_Click(sender As Object, e As EventArgs) Handles btnStart.Click
tmrStart.Enabled = True
CurrentTime = #0:3:0#
End Sub
Private Sub tmrStart_Tick(sender As Object, e As EventArgs) Handles tmrStart.Tick
CurrentTime = CurrentTime.AddSeconds(-1)
lblSeconds.Text = CurrentTime.Second.ToString
lblMinutes.Text = CurrentTime.Minute.ToString
If CurrentTime = #0:0:0# Then
tmrStart.Enabled = False
End If
End Sub
Much cleaner and easier to see what is going on. Also your statements to decide which minute is displayed in your original code appear to work correctly, but when the number of seconds remaining is exactly 120, or 60, the labels don't actually get updated. It doesn't matter too much in your code, but to be "logically" correct, they should be
If CurrentTime < 180 And CurrentTime >= 120 Then
lblMinutes.Text = "2"
ElseIf CurrentTime < 120 And CurrentTime >= 60 Then
lblMinutes.Text = "1"
ElseIf CurrentTime < 60 And CurrentTime >= 0 Then
lblMinutes.Text = ""
End If
Final small thing, there is nothing in your code to disable the timer then the time remaining gets to 0
Don't be put off by these things - humans are fallible - Me as much as anyone else.
I was wondering how I would go about fixing my countdown timer so that it shows the time in Hours:Minutes:Seconds?
currently, it only outputs the seconds and I'm not sure where I have gone wrong.
Any help is much appreciated.
Code:
Public Class Form1
Dim TargetDT As DateTime
Dim fields() As String
Dim Days, Hours, minutes, seconds, milliseconds As String
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
fields = Split(TextBox1.Text, ":")
Hours = fields(0)
minutes = fields(1)
seconds = fields(2)
Dim CountDownFrom As TimeSpan = TimeSpan.FromHours(Hours).FromMinutes(minutes).FromSeconds(seconds)
Timer1.Interval = 1000
TargetDT = DateTime.Now.Add(CountDownFrom)
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(sender As Object, e As System.EventArgs) Handles Timer1.Tick
Dim ts As TimeSpan = TargetDT.Subtract(DateTime.Now)
If ts.TotalMilliseconds > 0 Then
Con1Time.Text = ts.ToString("hh\:mm\:ss")
Else
Con1Time.Text = "0:00:00"
Timer1.Stop()
MessageBox.Show("Done")
End If
End Sub
End Class
Start by assigning the time you want to countdown to a TimeSpan field. When you want to star counting down, call Start on a Timer and a Stopwatch. In the Tick event handler of the Timer, get the Elapsed of the Stopwatch and subtract that from the original time to get the time remaining as a TimeSpan. You can then format and display that. When that time remaining reaches zero, the countdown has expired.
Private countDownTime As TimeSpan
Private countDownWatch As Stopwatch
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
countDownTime = TimeSpan.FromMinutes(30)
countDownWatch = Stopwatch.StartNew()
Timer1.Start()
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Dim timeRemaining = countDownTime - countDownWatch.Elapsed
If timeRemaining < TimeSpan.Zero Then
timeRemaining = TimeSpan.Zero
End If
Label1.Text = timeRemaining.ToString("hh\:mm\:ss")
If timeRemaining = TimeSpan.Zero Then
Timer1.Stop()
MessageBox.Show("Countdown complete")
End If
End Sub
That said, your specific issue is here:
Dim CountDownFrom As TimeSpan = TimeSpan.FromHours(Hours).FromMinutes(minutes).FromSeconds(seconds)
That does not do what you think it does. You're only getting the result of the FromSeconds call. If you want to create a TimeSpan with hours, minutes and seconds then call the appropriate constructor
Dim CountDownFrom As TimeSpan = New TimeSpan(Hours, minutes, seconds)
Of course, those arguments should be Integer values, not Strings. Turn Option Strict On and use the proper data types.
i want to convert total minutes into days hours and minutes. i am new to vb and still trying to learn...
this is my code...
Private Sub TextBox3_TextChanged(sender As Object, e As EventArgs) Handles TextBox3.TextChanged
TextBox1.Text = TextBox3.Text / 1440
End Sub
Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
TextBox3.Text = TextBox1.Text * 1440
TextBox7.Text = TextBox1.Text / 24
End Sub
Private Sub TextBox7_TextChanged(sender As Object, e As EventArgs) Handles TextBox7.TextChanged
TextBox1.Text = TextBox7.Text * 24
End Sub
When i run it i am having answers in decimal.. can anyone suggest me a proper way to do this? i do not want decimals.
It doesn't look like you understand the concept of variables, you don't need to have three different handlers to make this work, you can do it all in one handler.
You could do what you want arithmetically but in my opinion, an easier way is to use TimeSpan. It would look something like this:
'TextBox1 is where the user inputs the number of minutes
Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
Dim d = TimeSpan.FromMinutes(TextBox1.Text) 'creates a TimeSpan based on user input, this is also a variable creation
TextBox5.Text = d.ToString("dd\:hh\:mm") 'you can format it with a custom format
'Or you can access the elements of the TimeSpan like so
TextBox2.Text = d.Days
TextBox3.Text = d.Hours
TextBox4.Text = d.Minutes
End Sub
This is the scenario, I have three NumericUpDown for the values of second, minute and hour, And if a number is entered in the NumericUpDown i.e. 5, it will be converted to 5000 ms so my Timer can read it as 5 seconds. I'm trying to make a scheduler for every interval and this is my code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Label13.Text = TimeSpan.FromSeconds(Form3.NumericUpDown1.Text).TotalMilliseconds
Label14.Text = TimeSpan.FromMinutes(Form3.NumericUpDown2.Text).TotalSeconds
Label15.Text = TimeSpan.FromHours(Form3.NumericUpDown3.Text).TotalMinutes
Dim times() As String = {Label13.Text, Label14.Text, Label15.Text}
For Each time In times
Dim interval As TimeSpan = TimeSpan.Parse(time)
Timer1.Interval = interval
MsgBox("hey")
Next
End Sub
And it has an error at Timer1.Interval = interval that says Timespan cannot be converted to Integer, and i can't think of any way to fix this, can you help me out? TIA~!
Try This
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Timer1.Stop()
Timer1.Interval = New TimeSpan(0, 0, CInt(nudMinutes.Value), CInt(nudSeconds.Value), CInt(nudMilliseconds.Value)).TotalMilliseconds
Timer1.Start()
End Sub
Here are some ideas to get you past your current error.
Dim tsTest As TimeSpan = TimeSpan.FromSeconds(NumericUpDownTest.Value)
Label1.Text = tsTest.TotalSeconds.ToString("n0")
Timer1.Interval = CInt(tsTest.TotalMilliseconds)
Start with just doing seconds and when that code works see if you can add the others.
