Apr 14, 2011I have an application that provides a countdown for 60 minutes and I'm currently using the win form timer and it updates some labels and a progressbar.

View 6 RepliesRun A Thread At Set Periodic Intervals?
Sep 15, 2011look at the comments at the beginning of each class. Note, the period is rather small (100ms), and the process being triggered could occasionally take more than 100ms (in which case, the next thread trigger should be delayed ... two threads shoud never overlap). Also, the class will never be instantiated more than once.

View 16 RepliesToggle A LED With Timed Intervals?
May 4, 2010I have a piece of hardware that is controlled via USB.There are 8 LEDs on the output byte. One LED per bit.I like to toggle the outputs based on selection of checkboxes and given frequency entered in TextBox.I inserted 8 checkboxes to allow me to select the desired LEDs to be on.I select the checkboxes to select the required LEDs.The checkbox gives me the byte value. XORing the byte value with 255I can see them toggling very fast. I have a while loop to blink forever until I click on stop button.The stop makes the seq=false and this should stop the blinking but it keeps going.How can I insert desired delay of flashing frequency in my output routine?How can I stop on demand to change pattern without exiting the program.
View 2 RepliesWay To Control Graph Intervals
Dec 10, 2010I'm using the chart control that's built in to Visual Basic 2010.NET Service Pack 4.
I am creating a basic date time graph with time on the axis and, at the minute, random points between -20 and positive 20 on the y axis. At the minute I can set everything up perfectly. The only problem is that the label on the x axis is not a time, it's a number. To be precise, it's the XLabelInterval value. This value is a double, so the label on the x axis is also a double not a time. But that's only interval I am setting. I think, by default, because I am not setting any labels, it is just using that value as the label as well.[code]...

View 2 RepliesBar Chart - Y-axis Should Still Be Divided Into 10 Intervals?
Dec 28, 2009I am busy with a routine that will draw a bar chart.The X-axis is from 0 -100, no problem. The problem is the Y-axis.it will range from 0 to whatever the highest y-value will be.
My problem is that the y-axis should still be divided into 10 intervals, and the lenght of my y-axis should be the same in my picture box.I am using an array to fill the values, chartdata (0-9). It gets 10 values from the program. the values are 0 -10, 11 -20,21-30....91-100 . here is the code. It is working, but my Y-axis is messed up. Printing the labels of the y-axis is a problem.
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
Dim chartData() As Single = {mark0, mark10, mark20, mark30, mark40, mark50, mark60, mark70, mark80, mark90}[code]......\vb
Fixed Intervals On MSChart Axis
Jul 2, 2011I have a windows forms project in VS2010 with a simple line chart.The data is dynamic and always ranging between 1.4000 and 1.5000.I want the Y axis's gridlines/labels to always be displayed on every #.##20 data point, as in: [code] So I tried the Interval property for the axis gridlines/ labels, setting it to 0.002, and the result was that the gridlines/labels were displayed every 0.0020 points, like for example this: [code]
but not on 0.0020 points too as shown previously.

View 1 RepliesHow To Generate Random Numbers At Regular Time Intervals
Sep 29, 2009I want to generate random numbers at regular time intervals. I am putting the random generation in a loop which works when a button is clicked. But since the Timer itself is a control, I don't know how to do it. I tried putting the timer in a module so I can access it inside the form.
But the following error occurs:
"Error 1 Handles clause requires a WithEvents variable defined in the containing type or one of its base types".
When I doubleclick the timer icon the code appears as follows.
Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
End Sub

Stream Writer / Reader - Modifying Time Intervals
Apr 28, 2009I am new to Visual Basics and I am using Visual Basic 2008 express. I have been using video tutorial on line to learn VB and they are great in explaining what is happening the code vs. just looking at code. I think from what little I can find I would be using StreamWriter WriteLine and StreamReader readLine .I am using a couple of forms. I am looking for simple basic code to use a form as a way of modifying timer intervals and store the values in a single text file on separate lines.
Description:
Form1: will contain the main code that will run. It will contain some timers. I want the timers to look in a text file for their intervals. Each timer would be on a different line.
Example:
Timer1 interval would be located on line 3
Timer2 interval would be located on line 6
Timer3 interval would be located on line 20
Form2: will contain 3 textboxes. This is where when I load form2 I will also read the same values from the text file to preload the text boxes. I will now be able to change the timer intervals as needed and press a button to update the text file. The update button will also reload the new timer settings on Form1. This is very similar to how a CNC Machine works with Parameter settings. This can be useful for storing many different settings for a form that a user can modify and be stored and reloaded next time the program runs.

This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames.
