Another question for you... I have a program which lists the population from 1998 to 2002. The pop in 1998 was 300,000 but I need it to increase by three percent every year. My code works but for each year it has 300,000 as the pop. lic Class Population

I would like to know how to write the code for increasing number.For example. When I type a number in a textbox, after I pressed a button, it will increase from the number I've typed in the textbox with 1.For example : if i type 100 in the textbox,the number will go on.
101
102
103... to infinity

Why did they choose to add a new keyword AndAlso, instead of just changing the functionality of the existing And keyword?
Why would one want to use And, instead of AndAlso anyway?
Is it not just increasing the number of keywords unnecessarily?

How do i make the number in a particular column of an MS Access database to add up by 1(one) each time a button is clicked? I have tried the following code but everytime its clicked, it just seems to "replace" the 1 which is already in the database.
If CheckedListBox1.GetItemChecked(i) = True Then
ds.Tables(0).Rows(i).Item(10) = +1
da.Update(ds, "Students")
End If

I have a small page, with a button on it. When I click the button I'd like the code to look at a a field (call the field "InvoiceNumber") in a table (call it "InvoiceTable"), take the last number stored, increment it by "1" then store it back in the "InvoiceTable" and display the new invoice number on the page.Currently the button is called "New Invoice", so clicking this button is going to create a new invoice, with a number one newer than the latest one in the table.

View 3 RepliesI am currently running through a loop with 20 threads. These loops contain a series of 3 HTTPWebRequests (relatively CPU intensive). At the beginning, CPU usage never spiked above 10%. After about 7 hours of run time, CPU is spiking up to over 40%. I believe that this will eventually lead to the program crashing (it has before in less time, I modified some things and it seems to be running longer). What kind of intense CPU spikes are associated with threading? More importantly, how can the duration of runtime affect CPU usage by so much?

View 6 RepliesI'm building a VB.NET 2010 app that tracks battery usage. Run the app, start logging, then let the battery go flat. At the end, you get a nice graph that shows you how long the battery took to run down. Compare it to previous results and you can see how battery life is doing.
But this is supposed to be an unattended app, so it's not feasible for me to sit down and use word, browse the Internet, listen to music, play games etc. for four hours (especially at work!), so I'm looking for a way to artificially increase CPU usage to chew through the battery faster, and simulate how a battery would probably be used throughout a work day.
I've managed to inflate the memory usage using:
Dim a as long
Dim ptr(0 To 20000) As IntPtr
For a = 1 To 20000

I increase CPU usage in VB.NET? I've tried creating new threads with constant loops, but I get the funny feeling that VB.NET optimizes these kind of things to prevent memory and CPU hogging apps from taking over
I'm guessing the reason this macro isn't doing what I want it to is because of an error on my part in the code. Basically, I want the values in the cells pointed out in the code to be increased by 10% each time the button is pushed.
Here is the code:
Sub Add10percent()
IncreaseColumnValuesBy10Percent 2, 0.1
IncreaseColumnValuesBy10Percent 4, 0.1
IncreaseColumnValuesBy10Percent 6, 0.1
IncreaseColumnValuesBy10Percent 8, 0.1

View 5 RepliesThe program is to take an entered string then search for a subset of letters entered through and input box.In my subprocedure Sub btnSearch_Click I am using a loop to move through the entire length of an entered string to search for a set of letters entered through an input box. I can find the set of letters to search for but instead of increasing my counter "Found" for every instance of a match it returns the length of the string instead. I just don't know why the IF doesn't prevent the counter from increasing for every element in the string. I want the counter to increase only when the match is found. I just put 2 message boxes in there to make sure it found the right letter and then display the counter.

While using the Socket.Receive method to receive messages through network, you should define a variable as the buffer and you have to specify the length like this: Code: Dim _ReadBuffer As Byte() = New Byte(LENGTH) {} My question is: What is the bad thing about increasing the length of this variable even if the received messages are sometimes shorter? (i.e. if some body let it 10000).
View 1 RepliesI'm having an unusual problem that I've never had with WR's before. I have a very user-driven program that interacts with a server of mine through webrequests. Depending on what the user's doing, it could end up sending a dozen requests/minute. This has never been a problem before, but for some reason system memory usage increases and doesn't stop increasing, as if something is cluttering it up for every webrequest that is sent out.
Is there a known problem with WR's like this? Or is it just a random screw up? I can get my system back up and running smoothly.
I have the following code that connects to a server and expects data from it.Is it normal that working memory of my program increases every time I receive something from the server I connect to?The larger I make the network buffer, the more increase that is added to my working memory (in task manager)The data I receive is about 50 bytes. So I minimized that size of the buffer to 128.
View 1 RepliesI'm trying to write a simple load tester for one of our web services, which is served through IIS7. I'm launching a load of threads (as Tasks) that call the web service as a Web Reference.Despite the threads all starting, only 2 concurrent connections from the app can be handled by the web service. I'm aware that by specification simultaneous connections are limited to 2 per user. For the sake of this load tester, which I guess is one user, I would like to open many simultaneous connections.I have tried to add the following to the web.config of the web service.
<system.net>
<connectionManagement>
<add address="*" maxconnection="40"/>
</connectionManagement>
</system.net>
My setup is as follows:
The web service is located at [URL], where MyWebServiceApp is configured as an application.The webmethod can be viewed as something trivial that simply waits for, say, 20 seconds before returning a response (making it easy to see that only 2 connections are open at any one time).The simplest form of the load tester code is ass follows:
Imports System.Threading.Tasks
Module SuperBasicLoadTester
Sub Main()
[code]....
I've tried pointing other load testing software (e.g. soapUI) at the web service and have observed the same issue.
Edits: I should add that the web service box is running Windows 2008 R2.Also I have run SoapUI and my loadtester simultaneously and each is only able to request 2 connections each (i.e. 4 in total).
