System.Threading.Thread.Sleep [Resolved]

After some trial and error I found some articles about using the below code to delay an action from occuring.

Code:

---

System.Threading.Thread.Sleep(1000)

---

Sure it works to delay but it from what I gather only works on Win2k and XP and it puts the system to sleep for the specified time. "Meaning that nothing else will run" while it's sleeping.

Is there a better way to get a delay between two actions taking place and allow other actions to take place too?

I'm simply trying to show one picture box, hide it and then show another picture box beside it, hide it and then show another picture box beside it.

Point taken..... :bigyello:

My info must have been from a bad source. It still kills anything else from happening though from my experience. For example setting picture box 2 and picture box 3 properties to Visible/False and running the below code does not show the picture boxes going from visible to hidden, visible to hidden as it should.

Code:

---


Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click

            PictureBox2.Visible = True
            System.Threading.Thread.Sleep(1000)
            PictureBox2.Visible = False
            System.Threading.Thread.Sleep(1000)
            PictureBox3.Visible = True
            System.Threading.Thread.Sleep(1000)
            PictureBox3.Visible = False

End Sub

I have toyed around with the timer as you had suggested in your other reply to my picture box timer thread but didn't have any luck with it either. Any suggestions using the System.Threading.Thread.Sleep method?

Hi,

i'm using this method for my thread variables.

Example:
In my mp3 Player is a 'fadein' Function.

VB Code:

Private thFader as System.Threading.Thread();
 
Private Sub StartFadeIN()
  thFader = New System.Threading.Thread(AdressOf (FadeIn))
  thFader.Start();
End Sub
 
Private Sub FadeIn()
 do while mp3player.volume < 100
  mp3player.volume += 1
  thFader.Sleep(100);
 end while 
End Sub

(This Code is not Copy pasted, only from brain memory, it's bad ;))


There is no Problem, the System runs perfectly, while the thread is fading the volume.

Maybee you need another thread to start and use 'join' or something else to let the main thread wait for the other thread.

I find that when using Thread.Sleep as a program delay mechanism, you have to update the relevent object before using Sleep.

PictureBox2.Visible = True
PictureBox2.Update
System.Threading.Thread.Sleep(1000)
PictureBox2.Visible = False
PictureBox2.Update
System.Threading.Thread.Sleep(1000)
PictureBox3.Visible = True
PictureBox3.Update
System.Threading.Thread.Sleep(1000)
PictureBox3.Visible = False

You can also use the DateTime functions:

VB Code:

PictureBox2.Visible = True
            Delay5(5)                       
            PictureBox2.Visible = False
            Delay5(6)
            PictureBox3.Visible = True
            Delay5(7)
            PictureBox3.Visible = False
 
 
Public Sub Delay5(iDelay As Integer)
        Dim dt1 As DateTime=now
        Do
            If Now > dt1.AddSeconds(iDelay) Then Exit Do
        Loop
End Sub

I am so thankfull that there are a bunch of people all over the world that can get along and help eachother code in peace. :)

Watch the threads!! Gets a bit heated sometimes but it never comes to blows (and we usually end up realising we are all human:bigyello: )

Hi teamdad,

I've just noticed my suggested code for using DateTime did not reset the variable. I have edited that post accordingly and it now allow you to choose a variable delay period.

By the way, when you find some suggested code works (or does not work) it helps if you make a reference to the posting which contained that code. Otherwise we are not sure of the code to which you refer.
