Check If Int Is Within A Range?
Nov 4, 2009
On my form i have a textbox that users can enter a value into, how to i check whether the value entered in the textbox is within the range bewteen two other numbers?
i.e
Top int is 10
Bottom int is 5
The user enters 7 into the textbox
I want to check that the value entered is within the top and bottom range, and in this case as the number 7 is between 5 and 10 the answer would be yes?
If the user had entered 3 for example, then the answer would be no.
The Top and Bottom Int's will be set at runtime by the value entered into another textbox so will differ each time the user uses the form.

Is there a way to check if an IP address is within a certain range without having to iterate through a huge range of IP addresses?
For example, check if 10.1.2.3 is between 10.0.1.1 and 10.9.255.255.
I could also do with this working for IPv6 for futureproof my code.

Dim retValue As Boolean = True

I need to take six altitudes altitude1 and altitude2 and check to see if they are with in a value of 250 of each other. Then if there are any that are within 250 of each other, to make them turn red.
Second thing is:
I need to take 6 altitudes, and arrange them. I have them in panels and I have 6 empty panels as place holders for .location value however I need to know how to look at 6 values and say arrange these values accordingly highest number this place lowest number this place etc.
I have looked everywhere on the internet and maybe im just retarded when it comes to math in vb.net.

I'm using vb in excel 2007 and need to work through a range or array, the size of which varies from time to time.
The examples of using range always demonstrate using literals eg "A1:A25"
How can I programatically determine the end of the range - ie up to where the cells value is blank
And then can I use a variable in the range statement - eg .[A1:Lastcell]

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I'm building this class to download files in parts/sections/segments. In .NET 4.0, I can use this code to specify the range to download from
long startPos = int.MaxValue+1;
HttpWebRequest.AddRange(startPos);
and it works because there is a long overload for the AddRange method. When I looked up the .NET 3.5 version, I realised the AddRange() method allows using int only. The possible workaround would be using the AddRange(string, int) or AddRange(string, int, int) methods. Since the class will have to work in .NET 3.5, I'll have to go with the string specification but unfortunately I can't seem to find any sample code that shows how to specify ranges using this procedure in .NET 3.5. Can anyone show be how to do this?As the first code sample I wrote shows, I would like to specify a range of type long instead of int. Using type int allows requesting for byte ranges only up to 2GB but long allows requesting for byte ranges beyong 2GB.
The question therefore is: How do I specify byte ranges of 2GB or higher on HttpWebRequest in .NET 3.5?

I have a string array, and I need to get a range out of that, say 10 items counting from index 20.
I see there is an extension method called Take that can take a number of items from the beginning of the array, but I also need to specify the starting index.

Write a program that will allow the user to be able to choose whether they want to add up a range of numbers in one of three different ways. 1) even numbers 2) odd numbers, or 3) consecutive integers. Use buttons for user choices.
Instead of limiting the user to just adding up these numbers you will also supply an Average Button that will show the average of the numbers rather than just the sum. Only the result that they have selected should be visible.
The program should look similar to the program below:
This is the program I was asked to make.
my code soo far is.....
[code....]
I couldn't figure out the formula to use for this but I assume its the same for each part of the program just with a little change.
