In the following block of code always returns zero for the CPU usage. However, if I run it through Visual Studio in debugging mode, do a "Quick watch" on the variable "pcCPUCounter", add ".NextValue()" at the top, and tell it to reevaluate, that returns the varying percentage (eg, 5%, 71%, 16%, etc etc) as the processor utilization fluctuates.
Why would the code always print out zero, but the quick watch doesn't?
Private Sub UpdateCPUUsage(ByVal strSelectedServer As String)
'Performance items come Performance Monitor: perfmon.msc.
'The right-click on columns at bottom and select "add counter" to see list.
I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics Sub Main Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here pc.Increment() counterLabel.Content = pc.NextValue().ToString() End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.
I wrote a VB 2010 app on a single core processor utilizing performance counters which runs fine. However the release exe fails on my quad core, trapped by the OS on its first access to a PerfCtr. I've loaded VB Express Studio into the quad core and when running the app in Debug I get this error "Cannot load Counter Name data because an invalid index was read from the registry." Similarly, adding a counter to the app on the quad machine results in the empty drop-downs for category and it sub fields.
where I can get an update to these registry entries?
I don't see why this doesn't work. I have gone into the registry and removed the registry key below and still no joy. The error arises at the For Each Loop.
I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu If menuData.Children IsNot Nothing Then menuData.Children.AddRange(GetChildren(menuData)) End If Next
If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:
Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu menuData.Children.AddRange(GetChildren(menuData)) Next
Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))
how i could add like a counter sorta thing, like i know i would declare like lets say AttemptsDone as a integer then i say it = 0 then during my script do i just do like AttemptsDone = AttemptsDone+1 ?

i wanted to know how to create a for...loop...and specify the counter for the loop to control the animation time. I want the for..loop to increase the speed of the moving object (button) and move it 5 times...
the code i started with is
Private Sub ForNextButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xForNextButton.Click For Counter = 0 To 1000 'do somtething----the something i want to do is repeat the moving process 4 times and at a fast speed---how do i write that Next
Code: Public Class Form1 Dim dblPrice As Double = 0 Dim dblTotal As Double = 0
[code]...
I'm trying to get a counter going for radiobutton 3 which will allow the user to add an extra child or adult for a set price any one know how I can do this.
I am planning to keep timer in the form to start from 1 and increment every second. This timer shiuld stop when the other events are triggered in the form (like clicking a button etc).
how to add a counter variable to this array? My code always stops when it gets to an empty array. I can't figure out how to make a counter variable to make it stop.
Private Sub btnTwo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTwo.Click For Each i In PlayerArray
I have recently started creating a basic game however i am having some trouble creating a time counter. Basically what i want is a counter which is a label displaying say "05:00" as in five minutes. Then when the level is started i want it to count down to zero and make my game over label visible.
How to make my counter work. I keep feeling like I'm putting it, or maybe just part of it, in the wrong place so I've been moving it all over the place but haven't found anything that works yet. I'll paste my code below and it will be the code that seems to not stop when it reaches the end of my counter. Other ways I've tried it make it stop after one or two, depending on what I did to the code at them time.
Here's what I have at the moment: Public Class mainForm Dim guessCounter As Integer Dim correctAccumulator As Integer Dim totalAccumulator As Integer Dim answer As Integer [Code] ......
I am a new vb.net 2005 user and new to this forum.i need to know how u can pass a counter from one form to the next.am developing a computer based test and questions are on different forms so i need to know how the mark for a test can be maintained and added to from one form to the next.

I am trying to create a list box that can have things added and removed from it with the use of add and delete buttons in subroutines, i have also got a limit of 20 as the maximum number of items in the list box, also i would like the list box to be able to update the number of items in it after the user adds or deletes items from it: here is my code:
Public Class Form1 Private Sub cmdAddZp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddZp.Click
[Code]....
the first part is for limiting the number the user can add to the list box, the second part is the delete function and the last part is trying to count the number of items in the list.
How would I be able to make a textbox (counter). text = to something. Following an earlier example, I came up with the code below but it returns an error

Okay my assignment is to change a code up using two functions instead of a subprocedure to calculate total rainfall and avedrage rainfall and then to add a startover button to the application which not only clears all the labels but also clears the counter and accumulator. This is what I have gotten so far my functions do not work and I can get the labels cleared. I just can't get the counter and accumulator to reset back to zero
