PerformanceCounter Taking 40-50 Seconds To Be Created
May 26, 2009
I have a performance counter set up to pull % Processor Time on a remote machine.
Heres the code I use to pull it:
Code:
Private cpuCounter As PerformanceCounter = Nothing
Try
cpuCounter = New PerformanceCounter("Processor", "% Processor Time", "_Total", strServer)
[Code].....
However, sometimes it can take 40-50 seconds for this one counter to process.. when its been created (the 'cpuCounter =' line), then it runs just fine, I can pull nextvalue without any problem.. but creating it takes forever.
This only happens the first time I run my program and it only happens with the first counter, and it doesn't ALWAYS happen.

i'm making a small app to remotely monitor around 15 servers over our network, I need to get the current CPU usage, memory, disk space and network utilisation. I've got everything I need using performance counters in VB.net via the following (one for each item I want to monitor).
Code:
PerfCnt_CPU = New PerformanceCounter("Processor", "% Processor Time", "_Total", CurrentTargetPC)
PerfCnt_Mem = New PerformanceCounter("Memory", "Available MBytes", Nothing, CurrentTargetPC)
PerfCnt_Disk = New PerformanceCounter("LogicalDisk", "% Free Space", "C:", CurrentTargetPC)
PerfCnt_NetIn = New PerformanceCounter("Network Interface", "Bytes Received/sec", NetworkAdTarget, CurrentTargetPC
[Code]..
Is there a better way for me to watch the remote performance data, maybe through WMI I already connect via WMI to get the remote OS version, boot time etc.. but if anyone can give me an example of the most efficient way to watch the perf data over WMI (or a better way).

is it possible to monitor my RAM-memory use of my application using a PerformanceCounter? If so, I've been looking around on the web, but my knowledge about memory isn't enough to understand what precisely I have to use

PerformanceCounter.NextValue appears to return integer values instead of single values.The code below has a button, Button1 and a textbox, TextBox1. Click on the button and the textbox is filled with the CPU usage of each process at a given time. I would assume that these values should match with the values in task manager.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = Now.ToString & vbCrLf & vbCrLf
TextBox1.Text &= GetInfo()
Application.DoEvents()
[code]....
My guess is that these processes are taking up SOME amount of CPU and are just being rounded down to 0. In the first example I would guess that the CPU amount is rounded up to 100 %.

I want to convert seconds such as 254565443 seconds to hours, minutes, and seconds and thought if I could remove the decimal and the numbers behind it and not change the number in front of the decimal then it would work.
dim seconds = 254565443
dim Hour
dim minute

I'm using visual studio 2008 and creating a Windows For Application.
I'm almost completed my little application and what I've discovered just recently is that any change I made is not taking affect.
What I mean is if I change the display name of a button or insert a msgbox popup, it doesnt make it to the build when I run it. There are no errorswarnings.

If you want a instance of an object to be created when a form loads or another class is created, you have two options:
Public class example
private IAmAObject As IAmAObject
public sub new()
[CODE]...
Or like this:
public class example
private IAmAObject as new IAmAObject
public sub new()
[CODE]...
I always use the first one. It's more type work but I think it's neater. How about you people and is there any real difference between the two?

Is there a way to use ReadAllLines to read in a text file that contains some Chr(10) (linefeeds) but uses ONLY the Chr(13) (carriage return) as the true end-of-line?What I mean is, DON'T treat a Chr(10) as the EOL. ONLY treat a Chr(13) as the EOL.Obviously I could just read in the whole file as binary and then split it into lines by scanning for Chr(13), but I just wondered whether or not there's a setting in VB.NET to set the EOL character so I didn't have to do that.

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

I have this fingerprint scanner I'm working with. The fingerprints taken are index/stored in our imaging system and the fingerprints are put on certain documents and printed.When I scan the image in and then load it into a bitmap object, the width and height are (w:480,h:640).Now if I open this file in any image viewer and print it from there the finger print is as big as a fingerprint should be.Now when working with it in code, it's huge. I have found some resize code online, but the resulting image is horrible.Is there anyway to resize an image while taking in account the dpi and such so the image is highest quality (same as print out?).

I'm watching tutorials about creating Web Site and about controls.I think I added SQL Database to the project (it's not empty) properly. Suppose it has two columns: FirstName, LastName.I have TextBox1, TextBox2 and Button1 on the web site form.I enter any integer number (5, 10, 15 or whatever) into TextBox1. I want to press Button1 and get a value of 5th person (10th, 15th or whatever) from SQL Database into TextBox2.Who can help me with that? Should I read about ADO.NET and use something from there?Later I want to use VB for work with that strings.

I am trying to simulate human temperature taking. Basic I just need a button, a textbox , a progress bar and a timer. What I want to do is that when the button is clicked, the progress bar will slowly increment and after it reaches maximum, a random number in the range 35-40 will be generated in the text box.
Now so far, this is what I've done:
Public Class Health
Private Sub Health_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
[Code] .....
So this is suppose to be a temperature gadget for kids and therefore when a certain amount of temperature is reached...an alarm is sent to the parents. So the progress bar is working fine. The random number generator too. A "sent" dialog box is open if the temperature is >38.
1-The number is working. But I would like the number to b e generated AFTER the progress bar reaches maximum.
2-The sent dialog box is open basically the moment I click on the button to start the progress bar (if the num generated is>38). And it keeps up looping and opening.

i am changing the form's default location....... "" ....... "".. controls ( Datagridview controls) some column properties but nothing is taking in to effect, but in design time every thing is normal
NOTE:- no code is acting upon this controls IN FORM load or any other event, so i can't suspect that thing
