Count down timer [VB .NET]

[killman2639]

Hello everyone, i wanted to ask you all how to make a count down timer with only one timer (seconds) but including the hours and minutes(i.e. You can write the hours mins and secs you want (input) it to wait then make it count down with the secs timers) im sure i have to use if statements (If Label14.Text = "00" And Label15.Text = "00" And Label16.Text = "00" Then) something like that but im not sure.

thanks.

EDIT: Also could you tell me how to convert a String to an Integer. Ive tried Convert.ToInt32(textbox1.text) but didnt work

Hmm try this out. I don't know if this will work as I use visual basic 6 at school.

Val(Whatever.text)

Val = Value.

thanks nick, that works too. But i used this:

Code: Select all

         Try
            sec = TextBox3.Text
            Label16.Text = sec.ToString
        Catch ex As Exception
            Label16.Text = "0"
            TextBox3.Text = "0"
            TextBox3.SelectAll()
        End Try

EDIT: I might be posting the program when its done

Code: Select all

Convert.ToInt32(TextBox1.Text.ToString())

By the way for the count down I would make a new thread and use multi-threading to you'r advantage or use a background worker

Convert.ToInt32(TextBox1.Text.ToString())

Thanks smacked, ill edit the program right away.

EDIT: i know ull call me new but i tried this and it doesnt send any errors but it does not do the thing inside the if()

Code: Select all

Convert.ToInt32(TextBox3.Text.ToString())
            If TextBox3.Text > 24 Then
                Label16.Text = "0"
                TextBox3.Text = "0"
                TextBox3.SelectAll()
            End If

Whole SUB:

Code: Select all

Private Sub TextBox3_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox3.TextChanged
        Try
            Convert.ToInt32(TextBox3.Text.ToString())
            If TextBox3.Text > 24 Then
                Label16.Text = "0"
                TextBox3.Text = "0"
                TextBox3.SelectAll()
            End If
            sec = TextBox3.Text
            Label16.Text = sec.ToString
        Catch ex As Exception
            Label16.Text = "0"
            TextBox3.Text = "0"
            TextBox3.SelectAll()
        End Try
    End Sub

DOOOOOOOOOOOOOOOOOOOODEEEEEEEEEEE
you create an integer and then have that new integer = the converted form of that text box or have that convert thing were the text box is in the if statement.
works the same way as Replace() for text ie.

Code: Select all

Dim Blah As String = "Im such a negro"
Blah = Replace(Blah, "negro", "wigger")
'Replaces negro to wigger

by the way what are you trying to make a elapsed time or what ever or a clock?
cuz like i wouldn't use that many text boxes for a clock or timer... or elapsed time
as well it sounds like a GABEN program
