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]
I am using the following code in the Load method of a VB form to generate random numbers in the range 1 to 8. Without fail after enough loops the range is exceeded and 9 is the random number returned every time. The line using the Rnd function is from: Rnd Function (Visual Basic)

I am getting the error:"Range variable 'sender' hides a variable in an enclosing block or a range variable previously defined in the query expression."for this
Imports System.Data.SqlClient
Imports System.Linq
Public Class Form1
[code]....
I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.
Public extreme_foods As New System.Collections.ArrayList()
Dim i As Integer
i = 1
For Each s In split2
extreme_foods(i) = s
i = i + 1
Next
anyone know why extreme_foods(i)=s is giving INDEX OUT OF RANGE??
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?
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.

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.
i am using the below code but getting error.
View 5 RepliesWrite 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.....

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.
my question is to turn the text in a text box red when it receives focus, and black when it loses focus. I seem to get that "index is out of range" pop-up message. [Code]

I got help with pinging a range of IPs earlier and was given this code. I was then trying to change it slightly so I could scan more than my network between any given range e.g. 125.1.1.1 to 126.12.25.66.[code]
View 3 RepliesI'm getting the following error:
[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
System.DateTime.Add(Double value, Int32 scale) +7657639
System.DateTime.AddDays (Double value) +19
...
The line from which this error originates has the following code:
expires = Now.AddDays(30)
It occurs irregularly and irreproducibly. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative. It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Culture settings perhaps?
why does this return an error:
Dim stuff As New System.Collections.ArrayList()
Dim i As Integer
i = 1
Dim split As String() = temp_string.Split(",")
[code].....
the stuff(i)=2 line is returning the mentioned error
I've this very stupid litle problem. I want to populate a combobox with numbers ranging from 00 to 99. But when I ad them with a loop as an integer the first ten numbers apear only with one digit.I wonder, how can I ad a second digit to them like; 00, 01, 02... and so on without me typing the whole list?

Say I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.

3456 Lee
4567 John
There will be many more names but for this example you could use 3 or 4 etc..
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.
I have 14 values, that change constantly. I need to know how to check each value against each other to see if they are within 250 of each other. [code] I want these two values in the listbox to blink red in the list box. but i always want each value to check every value in the list box. i dont even know where to start short of programming each possibilty with a if than statement and that would take forever
View 1 Repliesis there a way to select a range of cells in a worksheet and clear the data in them?i DO NOT want the WHOLE ROW to be deleted, only a few selected cells (they are all adjacent to each other)and i don't think the ActiveSheet.ranges method works as:
1) the coordinates of the cells in the row to be cleared are determined logically by a VBA sub, i know how to get the coordinates, just dunno how to delete the row
2) this needs to be applied in different areas of the worksheet AND across OTHER worksheets as well.
I'm quite sure I have the logic needed to find the coordinates just need to know how to clear the cells if there is a way to do it that is similar to ActiveSheet.cells ( row, column ) then it would be best from my understanding the ranges method only takes in letter and number formats in strings... i need something that takes in number and number?
