Integer Arrays - User Enter In Big Integers Using - Two Parallel Arrays
Dec 10, 2009My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

Application Displaying Sum Of All Integers Entered By User
Jun 21, 2010I Create an application that when a user enters a positive integer value in a input box(the default number is 10) when the OK button is clicked, the application should display a message box with the sum of all the integers form 1 through the value entered by the user. If the user enters a negative value, the application should display an error message. I believe I have to use a loop condition but I have no idea what to do.
EX: User enters 10 in the input box once OK button is pressed a message box pops up and says "The sum of the numbers 1 through 10 is 55". Use the following test data to determine if the application is calculating properly
VALUE SUM
5 15
10 55
20 210
100 5050
Display All Even And Odd Integers Between 2 User Input Numbers?
Mar 23, 2009using for...next loop the program is supposed to accept 2 user inputed integers and display all even numbers between the two in one label and all odd numbers between in another label.
Private Sub displayButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles displayButton.Click
' displays the odd and even numbers between two integers
Dim intNum1 As Integer
[code]....
I'm not exactly sure what this code is doing. When I put 1 in the first number and 10 in the second number, the odd label only shows 9 and the even label only shows 10. Another example is when I put 2 and 15, the odd label comes out as 15 and the even label is 14. I'm very new to VB and programming in general and have just started getting into for...next loops and don't fully understand what the counter is or how the loop is supposed to work. I guess I'm having 2 problems. One is that I don't know how to make the program find the right numbers(my logic is off? or how I set up the loop isn't right?) and the other is the labels are showing only 1 number each instead of all the numbers in between on their own line.

View 6 RepliesArray Of Integers Comparing Integers?
Feb 2, 2012Basically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.
User Must Enter A Number Between 1 And 100?
Sep 26, 2009How do I make it that the user must enter a number between 1 and 100? And If they dont they get an OK messagebox stating that they must do.I imagine it'll be something like this:
If TextBox1.Text = "" Then
MessageBox.Show("You must enter a value between 1 and 100", "Name Entry Error", _
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
End If
But Im not sure whats suppose to go inbetween the speech marks.

In Percentage, Should Expect The User To Enter 4 For 4%?
May 24, 2010If we format a value for percent "{0:#%}" then it will become 400%, and this also applies to all the 3rd party controls I've tried. I've used custom format as a workaround for this but perhaps you guys could enlighten me on this one. If a user inputted 4 for example then did the user intended 4% or 400%? If it were me that I would expect the 4 to be 4% rather than 400%.

User To Enter Up To Five Passwords At One Time?
Oct 26, 2011I need to write a program allowing the user to enter up to five passwords at one time. I have the textboxes set the way I need. When the user presses the button, the code should check every password they ve entered, and flag any passwords that are invalid. A valid password includes the following:
At least 6 and not more than 15 characters
At least one uppercase alpha character
At least one lowercase alpha character
At least one numeric character
I'm a little confused about how to check each character of the entered passwords for these conditions.Because it must include alpha characters, I believe I have to do something with ASC and CHAR variables. This is my first post and I need to have this done within a few hours, haha. Help would be awesome.

AutoComplete Textbox - Start Again When User Hits Enter

Datagridview - Formatting Don't Applies When User Manually Enter A Value
Nov 19, 2010The situation: I have a datagridview with one column (col1). In the datagrid definition (design view), i have created this row, and set the formatting to C2 (or C0, or C - I tried them all). then, I load my datagrid view pro programmatically :
dbl_myValue as double
dbl_myValue = 6.99
datagridview1.item(0,0) =
dbl_myValue
The datagridView shows the data correctly : 6.99$. When I "spy" on the datagridview.item(0,0), the "Value" property is a Double.
the problem: It don't work if the user manually enter a value : click in the cell, enter a numeric value (let's say 100, without decimal to avoid complexity) and then LEAVE the cell (so no more in EDIT mode). The formating just don't applies. When I "spy" on the datagridview.item(0,0), the "value" property is a STRING. So I guess this is the problem, but how can i do?
