I've been running through the online "Code Rules" tasks to work through Visual Basic. However I seem to be having a problem with one. The objective is to set a Button Click method to check if any number between 2-5000 is prime or not and to display it in the TextBox if it is prime. Here is what I have so far but it doesn't seem to work.[code...]

View 3 RepliesI'm working on a console application in VB .net that checks a number that the user has inputted, and tells you whether the number is prime.
The number that has to be inputted has to be between 1 and 100. I have all the code so far and at the moment it can check whether the number is or isn't within the boundries.
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
If ......
result = false
I just started to use visual basic last month and I only know the basic codes. No matter how hard I try to understand the codes given by the other member, I can't understand it.So the program I'm making is to show all the inputted values and determine the even numbers, the odd numbers and the prime numbers.I don't know how to get the prime numbers.

I've been trying to create a function that checks if a number is a prime. according to [URL]..I have created a function although It doesn't work as expected.

It sometimes returns true for composite numbers. oh and I know if you google it you get functions that do this, but most of them look inefficient so i'm trying to make my own.
i wrote some code that is suppose to get the prime number from the user and give its factors but there's some error

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

View 5 RepliesI'm having trouble lining up data from a file with their respectable columns in a list box. I am using print zones to space out data evenly, but when i run the program the output is still messy. So I need lining up columns properly together. As of now, the first 2 list box items line up with each other perfectly, the data i am looping through to add to list box is not lining up correctly. I have changed my zones several times, but still no luck.
