I have a listbox that prints 2 different values each line. The first one is String and the second one is an Integer, (although I've converted it to String). How do I extract the first String value? One is suposed to be able to mark one line, and remove the selected lines values from 2 different arrays, and for that I need the String value.

I'm trying to parse this XML for the values of puppies and kittens.
<Pets>
<Puppies>4</Puppies>
<Kittens>2</Kittens>
</Pets>
Here's my code
[Code]...
On the first read, the element name is "Pets" and the Case Else gets hit. On the next read, the element name is "Puppies" and puppyCount is correctly set to 4.
But then it seems to skip over "Kittens" and go directly to the inner XML. What should I be doing?
EDIT: XmlReader is faster than other .NET parsers, but my files are small enough that it's probably not a benefit. Joe Ferner's tests. EDIT 2: There's a reader positioning problem in the original code.
Lets say I have a string that could look like this[code]...
I want to break each of those in to two strings. The break point would be two decimal places to the left of the existing decimal point. So in the first example I would end up with 123 and 07.37 and the second example I would end up with 44 and 01.0. I assume I need to use a form of .indexof("."), but I cant figure it out.
Looking for the simplest way to extract values from a string. For example consider the following:Dim args As String = "/firstname:Bob /lastname:Jones"..To simplify, I need to be able to popup a box that says "Firstname = Bob" or "Lastname = Jones"

View 11 RepliesI have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-

I have tried to create an amortization program The issue that I am having is that the program wants to print the same page over and over again. The first page of the printout runs through the "While loop" appropriately, but when the second page starts printing, it repeats the information that is on the first page. This is true of all subsequent pages I have included the printing portion of the code.

View 2 RepliesVisual Studio 2005 I have an application that prints formatted text to a printer. I'm using the sample code from MSDN to impliment PrintDocument.PrintPage. My function for formatting the pages uses exactly the same code.
The problem is that the actual printout is off by one line. The footer from the first page prints at the top of the next page. Subsequent pages scroll down by one line for each page printed. If I reduce my formatted text lines by one, the opposite happens... the header from the second page prints at the bottom of the first page.
I've fussed with margin settings and fonts and I just can't seem to make it print pages correctly. I'm hoping that someone out there has seen this and can offer advice.
