Determine Prime Numbers - Calculate Button?
Mar 17, 2011I am creating an application that takes two numbers (lower and upper) and determines the prime numbers
Public Class primeNumber
Private Sub calculatePrimesButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculatePrimesButton.Click
'declare variables
Dim number As Long
[Code] .....
Once I hit the calculate button nothing comes up. I've tried adding the first code inside the function with the remaining code but no result. Now I'm putting the first code in with the calculate prime button. I am guessing there's a sqrt method that needs to be applied but I am not sure if it should be part of the function or the main?
Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers
Oct 4, 2011I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
How To Determine A New Line In A Text Box
Mar 16, 2010i have designed a form that generates e-mails for outlook. the form has a textbox which allows the user to write extra notes. these notes are then added to the e-mail body at the end.
here is the issue, suppose the user wants to enter the following as extra notes.but when i actually add this to the end of the e-mail body i get something like this
"Please send us a replyyours truly,user" i has similar issues when i was generating the e-mail body as i was not using the default SMTP client server but some other methods to generate the e-mail
i know how to make the characters come to the next line, but i do not know how can i determine when the user has moved to the next line is there a way to determine this, and if there is how can i replace it with this character " %0d%0A"

View 3 RepliesText Phrase Identification - Determine Type Of Input?
Feb 22, 2009I'm trying to identify if the input of a textbox is non numerical, which cannot be converted to an integer/double for calculation. I do this by converting the input1.text to ascii, and looking at the value to determine the type of input. My question is whether there is any way I can analyze the whole input character by character? Asc() only gives the ascii value of the first character, but what if the input is "9W" etc? Such inputs will pass my character test, but cannot be converted to an integer.
View 2 RepliesScan A Text File To Determine If It Is A Text File And If It Contains Any Non-ASCII Characters?
Jan 27, 2012what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

View 4 RepliesNumbers Spin Around In A Text Box Before Being Selected
Feb 20, 2012how could I make it so that numbers spin around in a text box before being selected. I have five text boxes the start button spins the numbers 001 to 500 in each text box, then when a button under the first text box is pressed the numbers stop spinning and the chosen number is displayed, you then press the button under the second text box to stop the spin and that chosen number is displayed.My thoughts are, have the first button select the five numbers and place each in a text box but have the text boxes visible set to false, have five more text boxes, visible.true, that show spinning numbers, when the button under the first box is pressed the textbox with spinning numbers is set to false and the one with the chosen number is set to true.This is only for decoration purposes so that you get to see the numbers spinning before you appear to stop them.
