How can I join more than one integer number to become one integer (Long) number?
e.g. 2, 3, 2 and 5 = 2325
123, 7 and 2 = 12372

0, 10 and 450 = 10450

View 1 RepliesSimilar in concept to Math.Abs() - I'm looking for a function that when given a positive integer will return the same integer. If given a negative, will return zero.So:
f(3) = 3
f(0) = 0
f(-3) = 0
Yes, this is simple enough to write on my own but I'm wondering if the .NET Math class already has this built in or if the same can be achieved by cleverly chaining a few Math.* calls?
Is it okay for a structure variable to hold a small number of reference types? I thinks it's fine because the pointers themselves are not that big, regardless of what they're pointing to. But I never did fully figure out the whole heap/stack thing, so I'd like to make sure.

I don't know if I worded this properly, but I have a mdb query that I display in a Datagrid on my form. The first column is TransactionNumber, which is the primary key and a running total (ex. RackingTransactionKey=RackingTransactionKey + 1). What I need to do is when the form is opened, find the highest (last) TransactionNumber from the query or Datagrid and assign it to a variable (RackingTransactionKey), so I can can update it (+1), therefore generating a unique number so I can add data to the query.

I am reading an excel file and storing the string value present in each cell, and trying to match the string in a word file.
The program works fine except that I am having problems in returning the page numbers of the matched string.
The page number value is always returned as one.
The following is a piece of what I had written:
If FindStringInFile(wordfilename, vValues) Then

TextBox3.Text = currentPageNumber

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.

What i'm trying to do is compute whether an integer number is prime or not. The program performs this analysis for all odd numbers from 3 up to an input integer limit, for example 100. If the integer in the range 3 to limit is prime, a message stating so is printed. Otherwise, a message is printed that lists at least one other integer divisor. The output for each analyzed number consumes one line of text.
A sample output is shown below:
Limit is 100:
Number 3: is prime
Number 5: is prime
Number 7: is prime

I understand I need to use loops, boolean functions, vbmath(), strings and multi-line out via concatenation. So I can put this is words how I think it should be done but not so great putting the code together
Test all integers up to the SQRT of the number (100)
limit = math.sqrt(100) + 1
Followed by 1 For statement
For c = 0 to 100 step 2?
And an If statement
