I am working on a small program to teach myself how to use timers, and I would like to know if there is a way to make the timer control faster.I set the Interval property to 1 and it is to slow for what I am trying to do.(All I am trying to do is loop a button left to right, right to leftand so on in a Panel)
View 39 RepliesI need to perform a huge amount of registry read operations, and I'm trying to figure out a way to make each read operation faster than using My.Computer.Registry.
If I used APIs directly to do it, it should be faster, right?
how can i make a Label control to have the present day an time value and also make the time tick as in a normal digital watch.
View 2 RepliesI am trying to make a timer, inside of a class, tick, by calling it from a backgroundworker. It never ticks (the Tick event is never raised), but the Timer shows as Enabled (with Interval set to 1).
Here is the simplified
Class1.vb
vb.net
Public Class Class1

If I move the code inside the Thread1_DoWork procedure into the Button1_Click procedure, the code works fine (by bypassing the backgroundworker). But, when it is called inside of the backgroundworker, it doesn't work at all.
I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?
I've tried a couple things to add items to a combobox (I've also Googled a lot but haven't found anything for VB2010) and on top of that, how to make it so that if the user selects 10ms, it changes the Timer1.Variable to 10.
Here is my progress from what I found on Google
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
ComboBox1.Items.Add("10ms")

I`m fairly new to coding (2 weeks) and having some trouble with a timer application to control a greenhouse misting system. The problem arose after resolving the 65 second interval limitation for tmrPause, it appears the tmrPulse line is never reached as lblCycleStatus.Text doesnt display "Pulse" where it did before. I may have bitten off more than i can chew for a first project but i`d appreciate any pointers as to where i went wrong so i can learn from it.[code]
View 5 RepliesI'm trying to make a little app that displays the battery life of a notebook, and also whether it is charging or not.I've got it displaying the battery percentage and if it is running via the cable or battery alone.My problem is that I have a timer constantly ticking to grab the latest information as to whether it is still chraging, what the battery % is like, however for some reason when it first runs it get's the info but then that's it, it won't refresh the info in real time. I'm confused because the battery can deplete but the program only displays what info it got when it was first ran but if I unplug the power cord or plug it back in it refreshes that info straight away. My code is:
Public Class Form1
Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
Dim GraphicPercent As VariantType
[code]....
The bit I've highlighted in red in my code won't work either, basically I've shaped the two labels to look like a crude battery shape and label2's function is to represent the nobly bit at the top of the battery and I wan't that to change to Lime when the battery is 100%.why it won't refresh the graphical output to the screen?
Im using RichTextBox from Visual Studio 2008 to show various RTF content and it is slow. I mean really slow. Is there any way to improve the loading speeds of LoadFile function?I tried to load directly from memorystream (without saving file to disk) but it's still slow.I read plenty info about how RichTextBox is slow and all. Has there been any improvements in Visual Studio 2010?

i have a program in VB.Net 2005 and my problem is that it runs very slow. I mean, it takes some time for the Form to be displayed even if it is not doing anything in the Form_Load event. Do all programs in VB.NET 2005 act like that? my programs in VB6 would display the Form instantly.
View 4 RepliesI have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:

View 2 RepliesBasically what i need is for something to look at the items in a list box then compare it to the contents that is in the database. The issue is that the listbox can have more than one of the same item. For instance, LstBox_Order.items(0) could be the same at any position in the listbox. This code works, but it is slow if there is like 10 or more items added.

View 12 RepliesI have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.

The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.

OK, I've been searching for hours trying to find the best way to fill a listview from a comma delimited file but have come up empty handed so far. Currently I am using code I found on the NET, which works, but it is EXTREMELY slow. As a test, I created a file with 5,000 rows, and 10 columns. The column layout is as follows:123,NAME,NAME,NAME,NAME,0.00,NAME,YEAR,NAME,1
Dim ofd As New StreamReader(".dataCardData.bct")
Try
Using reader As New Microsoft.VisualBasic.FileIO.TextFieldParser(".dataCardData.bct")
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")
[Code]...
The code I am currently using appears to be loading the file and somewhat simultaneously filling the listview at the same time. I feel that I should load the entire file into an array or arraylist and the send the array or arraylist to the listview. However, if this is the best way to do it, I have not been able to find any examples of how to do this.
I have an array of approximately 1000 classes. All of these classes must have one of their properties changed to the same value. I need this to be as optimized and fast as possible.
Would LINQ be faster than a for-loop? Any other ideas for faster execution?

Suppose you have an array with 10.000.000 elements filled with values between 1 and 10, and you need to count how many fives it contains, something like:
Dim RandList As New List(Of Integer)
Dim r As New Random
Dim Counter As Integer = 0
For i As Integer = 1 To 10000000
RandList.Add(r.Next(1, 10))
[Code] .....
Here I got 2 problems, both versions are returning different values at each call with the same array, and the sequential ForEach is being executed much more faster than the parallel.
