I am iterating processes using the Process class GetProcesses method. I would like to display information formatted similarly to the way the TaskManager displays it. Where to I get the CPU and Mem Usage data that the TaskManager displays?
View 2 RepliesSo the below code is supposed to loop through all the processes and fine all those who's title contains "eReceipt". I want it to report the number in OpenReceiptCount.What it does however is only return 1, no matter how many are open. the titles are all very idential aside from a receipt number. And I can see each processes show up with a title that DOES contain eReceipt (hence the messagebox) but after it counts the first one and sets OpenReceipt from 0 to 1 it will not count any others.
Dim OpenReceiptCount = 0
I am fairly new to VB.NET (but have vast professional experience with several other languages) and am completely new to these forums (so please don't burn me if I posted in the wrong place). I have run into a rather odd quirk with System.Diagnostics.Process.GetProcesses. I have a sample application (source posted below) that checks all running processes every second for changes (created and destroyed) and tells the user what has changed, if anything, in the last second. The sample runs for anywhere between 29-72 seconds before issuing an array out of bounds error. It appears that the Windows system processes, SearchProtocolHost.exe and SearchFilterHost.exe explicitly, disappear from the list causing my application to throw the aforementioned exception. Specifically the exception I am receiving is as follows:
Unhandled Exception: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.I have noted in comments where the exception is thrown in the code below. If any of you would be willing to try this sample on your PC's or could suggest potential issues with my sample that could cause this problem
My sample code:
Imports System

VB.net 2010 Read all around the net, but cannot seem to do this: Tried the performance counter Categoryname=process Instancename=("program"). _Total helps in part- but it would be more efficient to acquire the main applications cpu usage for this project.
Code:for each p as process in process.getprocesses if p.id=process.getcurrentprocess.id then end if next 'Values, Obviously multiple processor cores have to be taken into account'kernelmodetime, usermodetime, Cputime, total cpu time, 100% <-- Does this involve adding and or dividing all these times? I need the current process CPU usage.
I have three class files, accounts.vb and transactions.vb in addition to my form.vb. I am unable to retrieve a member variable from on class from inside the other. When the combobox index changes, the program loads the correct account (checking or saving) from two different sequential files. I don't think I have the calcBalance procedure in the correct class file. And that is what I am having trouble with. Accessing it to display it. [Code]

first of all, I'm not 100% sure this is the right forum to post this, as there seems ot be tones and tones of forum branches here, so if I'm not in the right location, i'm creating an IDE for a proamming language and I need a way to monitor the physical memmory usage of a process tree. I'm not talking about the WorkngSet64 of a process, but the WorkingSet64 of the process and any child process started by it.

I have a problem with an application, in this case I have a windows services. its function is generate reports depending of demand of our users.In some cases the memory usage of my windows services is to 2 gb of RAM. I disposed all objects that my application use . but the memory usage doesn't low.I tried to reduce the memory usage forcing to garbage collector to Collect with the method "GC.Collect"but it's not recommend because uses many time of CPU.Surfing on the internet I found a method named "SetProcessWorkingSetSize" that free memory usage correctly. http:[url]....but some cases my windows services named sapdkadm_procesoestandarejecucion.exe has some error message in event viewer is the next:
Faulting application sapdkadm_procesoestandarejecucion.exe, version 1.0.0.0, stamp 4f908fef, faulting module kernel32.dll, version 5.2.3790.4480, stamp 49c51cdd, debug? 0, fault address 0x0000000000027ded.

I'm doing a project for my beginners programming,logic, and design class. The project is a Sales Solution/Bonus Calculator. I really just want to know if I actually coded the array correctly.

I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.
