ScrollToTop And AJAX - Increasing The Length Of The Timeout?
Sep 10, 2010
I'm attempting to have my page automatically scroll to the top when there is an error message to present to the user. Following a tip I found searching, I've enclosed the Javascript scrollTo function in a setTimeout function to avoid a conflict with AJAX remembering the scroll position. Here is the relevant [code]....
This is working fine for me locally, but when I move the code up to our test server, it does not seem to take effect.I have tried increasing the length of the timeout, but no dice.

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).

I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

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

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.

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?

I 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?

I placed a button on my form that measured 59mm in width (approx 2.25 inches for any Americans).When you run the project as you'd expect it still measures 59mm.However when I set the form as a child to my MDIParent and run the project the button now measures 67mm (well over 2.5 inches) an increase of 13.5%.Is this a bug or do I need to just change some setting somewhere?

I am struggling to do what i want with classes at the moment as they are killed off at the end of a method, can somebody let me know how to make the classes live until i tell them to die? so that i can create one and refer to it from another method at another time? For example On form load i create a class Dog.Then later on i want to get info from the Class Dog. But it is no longer instantiated

I'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

My application has 1 main form and three other forms which raise events to my main form. I noticed that the memory starts at 77,000 K and increases substationally over a few hours maby be to 250,000k and ever increases.The main form has a dataset and a bound datagridview which gets refreshed with data. Basically it's a taxi booking application. The booking form raises an event to the main form and the main form refreshes the jobs and displays them on the dgv.

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")

The 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.
Here's the entire

I'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.
