Setting An Interval For A Timer In A Textbox On The Form
Mar 31, 2010
I don't know much about vb.net so I'm hoping this is something that can be done fairly easily. We currently have a system where valves are fired by checkboxes (representing each valve) being checked at certain intervals and when the last valve is switched the timer restarts in order for the sequence to repeat itself. We would like to be able to have a textbox in the form where we can just type in the interval at which the valves (checkboxes) switch without having to change the interval manually in the code each time we want to change it. Currently in our code we just have a set interval. Here's the code:

I want to make my form freeze for 5 seconds before it resumes to the next form.So I have a form that says : Establishing a connection....
But I don't want it to make a connection, i just want the user to think that it's making a connection.
And I then want it, when the timer reaches zero, that it would resume to the next form.
I just need the code of the timer behavior.

So, I have two timers. 1 Timer is set with an interval of 1000 (milliseconds), therefore it goes off every 1 second. For some reason, when I set the interval on the same timer to 1, it goes off 100 times every second. Shouldn't it go off 1000 times every second? What's going on?

How can I get a timer to run one interval,one interval only, and stop? Until now I have only used timers to keep running until I say to stop. Also I need a timer that will start at the beginning of, and run until any given process is completed.Upon completion it should shut off and tell me how long the process took. Kinda like a stop watch with a Stop / Start "Trigger".

I have an animation program which allows users to import and animate images. I do this using timer events. I have a listbox which contains the image references, and a Image which displays the chosen image. Here is the
When the user clicks the "Animate" button:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles animate.Click
Dim cananimate As Boolean = True
[Code].....
I want to make a dialog to appear and allow the user to select a custom FPS for the animation. For instance, if they type 15, the listbox must go down 15 images in 1 second. But how do I convert FPS to a timer interval?

How would you make the Interval of a timer to be between two times.
E.g if you wanted an event to occur between every 7 and 20 seconds?

I am trying to write a simple code that will essentially change the background oclor of a form from say red to green, like every five seconds.(Actually, it will be green 4 and red 6 seconds). I set my timer interval to 1000 and enabled it. So when I write my if/then statements in the timer area, would I be using timer.interval <=4, or timer.interval <=4000 to count off four seconds?

I have dragged and droped a timer control "tmrGetMappingXML" from the Common Controls Tab in Tool Box. The issue that I am mentioning also appears for the Timer Control present in the Components Tab in tool box.
In the form Load I have written:
HTML
tmrGetMappingXML.Interval = 3600 '1 Hour = 3600 Seconds
tmrGetMappingXML.Enabled = True
tmrGetMappingXML.Start()
The timer interval is also set in the design time to 3600 seconds. But the Tick event of the timer fires continuously every second.

I have an MDI form, and all of its children have a timer control. I also have an options form where the user can change the automatic refresh interval, which is loaded from the parent. The interval is stored in My.Settings.UpdateInterval as a Double.What is the best way to update all of the timer interval of the Children? Can the Children listen for an event in the parent form (UpdateIntervalChanged)?

I have this code in one button:
For Each x In ListBox1.Items
Label1.Text = "Status: Loading IMDB page..."
Dim str As String = x
Dim MOVIESNAME = str.Substring(str.IndexOf(""c) + 8)
[Code] .....
Is there an option to set a time interval between each check? Because it will load the page (it's not google, it's my personal website with some information needed) and it need to be fully loaded till it gets the information then it would do another check for another listbox1 item. Like.. maybe 5 to 10 seconds is enough..
Webbrowser1
Dim strCDRack() As String
Dim cdList As String
'Dim i As Integer
cdList = WebBrowser1.DocumentText.ToString
[Code] .....

I'm working on a small game that I want to sync with the intensity of the music. I have a timer added and I want the interval to change with the intensity of the song playing. How would I go about doing this? I tried playing with Zplay and BASS.net with no luck.

my function is to adjust a timer interval according to a integer variable.
Original code (works fine):
Code:
Dim UpdateSnakeSpeed
Select Case UpdateSnakeSpeed
Case currentscore > 199
[Code]....
This is the code I'm using right now. (works fine and is more logically correct than the above case statement. I have chosen to go with if .. end if statements over case, as I do not have a full understanding of what the variable SnakeUpdatespeed is doing in the Select case statement. If someone explains then I'll consider it. Also I know case statments are only meant to be used for 1 option selections, however I'm amazed that it still works in case. Atm it's going to be if end if. Now I'm trying to get the for next loop going with this (if it's logically possible). that's what i'm aiming overall out of this thread. To make a convenient loop.

I have been making an online role playing-game in VB2008 and inside the gameloop for the client there is some code that "smoothes" out the movement (instead of it being choppy from tile to tile.) It works pretty well but I'm having problems figuring out a math formula to get a good frame timer interval to set how fast the frames change based on how many pixels they can move per loop.Testing stuff out I found that 250ms is an ideal frame timer interval for 1.0 pixel movement per loop. If I were to double the movement step of pixels by 2 lets say (2.0 pixel step per loop) I found that the frame timer interval should be around 125ms. How can I get the frame timer interval by the movement step of pixels? In cases where the movement step can anything between 0.1 to 4.0 pixels.

I have an application that updates a great number of fields on a pretty short interval timer. (on a standard form)Question is as follows... which one of these statements will work better for this? (working better = faster/smoother)Dim textToUpdate as string
if textbox1.text <> textToUpdate then textbox1.text = textToUpdate
OR textbox1.text = textToUpdate

I'm doing an application for a school to help them keep track of student attendance and because I'm rather new to VB 2008 .NET I'm sure I'm missing something simple.see the screen shot and attached sample application showing the problem I am having.
The screen shot shows 3 open forms. I'm not able to get the value from the 3rd open form into the Student ID textbox of the 2nd form even though my messagebox shows a value is really in there.The attached application has 3 forms similar to the production application I'm writing which also includes 3 forms. Could you look at the application and tell me what we are missing to get the textbox data in the 2nd form to show up?
