VS 2008 : Creating Asterisk Square Using For Loops?
Oct 26, 2010
I'm having a little trouble with this assignment for my 1341 Fundamentals class... Add another TextBox and Button to your program window; label the TextBox side: and change the Text of the Button to Print hollow box. Write code to clear the ListBox and then print a hollow square box of asterisks with sides of length equal to the input number. For example, if the number entered is 10, the output should look like
**********
* *
* *
* *
[code]....
You may want to use a For loop inside a For loop. Use a string to build each line of output before you send it to the ListBox. Your program should produce correct output even if the input is 0 or 1. Be sure to catch all exceptions and handle them intelligently. After this step, your program window should look like this.
NOTE: I had some trouble getting the desired output for the 10 and 4 user inputs to print out right... Rather than there being 2 rows next to each other, they should be spread apart by the number of asterisks on the top (and bottom...) thus creating the "asterisk square".
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim first, last As Integer
Try

I am trying to learn by creating a small application to help my son learn math. It works but I know there are better ways of accomplishing what I need.
For example:
'Declare variables
Dim num1 As Double = CDbl(frmMath.txtNum1.Text)
Dim num2 As Double = CDbl(frmMath.txtNum2.Text)
Dim answer1 As Double = CDbl(frmMath.txtAnswer.Text)

I imagine I would need something like a do while loop?

the purpose of the program is to display the monthly payments on the loan.My homework is to use do while loops instead of for loop.Here is the code for the for loop.
Option Explicit On
Option Strict On
Option Infer Off
[code].....
Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.
Here's the do while loop code
Option Explicit On
Option Strict On
Option Infer Off

When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.
My function(It will atleast search once):
Function RealContains(ByVal load As String, ByVal needle As String) As Boolean
load = load.ToLower

This is my first time using DataGridView, and I've managed to solve most of my problems but one.In my datagridview table, I want the user to be able to add and remove rows as they please, they just select the row, click delete, and that row is goneMy problem is there is a row that is labeled the "new row" (i think?) that has an asterisk beside it(to the left) that will generate an error if you try to delete it.How do I remove the asterisk beside the row and make it so the row is deleteable by the user, and that it will not generate an error?Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Try
If DataGridView1.CurrentRow.IsNewRow Then
'This is not ok. I do not want to have to have this If section here.

I have an arraylist of strings, one of them looks like this:It's wet out here and [player id=3686163]Ripper[/player] knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
I need to remove the square brackets and the contents of them, to give:It's wet out here and Ripper knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
The contents of the square brackets are likely to change from string to string, and in some case I may have more that one player in that string.

The app then displays all the odd numbers between both integers and all of the even numbers between both integers. There are two text boxes and two labels: even and odd. How would I code a For..Next loop for this type of app. The part where I get confused is what do I determine and how do I

I've had no issues with this in C++, however, in Visual Basic 2008 (not sure about 2010), when I run a Do loop of any type, and run a comparison to 0, or even 0.0, the code loops a second time.
[Code]...
To my knowledge it should cancel after the 5th line, since the condition is satisfied. However it does not. Instead it runs the loop one last time.If I put in a comparison of any number higher or lower than 0, it works as it should, and cancels properly when the 5th line is written. So 1, -3, 0.0001, etc. works, so the problem lies with 0.
Now I do not know that much about the debugger, but it should be mentioned I'm running express edition, and I could not find anything that lets me see how each line compares. Nor, after an hour of searching online, could I find a single forum where this is answered (though perhaps that is due to how I worded my search).
If someone could explain to me why the comparison does not work as it should and loops a second time when comparing to 0, or even 0.0 (one person thought it was a difference in balance being double and 0 being an integer),

I have a piece of my code that uses a for each to loop a certain amount of times depending on how many saved fields there are in an xml.
vb.net
'// Write an .html file ready for debugging
If (File.Exists("Working/" & textBoxCampaignName.Text & ".html")) Then
'// Do nothing the file exists
[Code]....
So the for each loops depending on how many nodes it finds in the ("/campaign/secondarySection") this works great, it loops accordingly, what i'm trying to figure out is a way for a messagebox to show once the loops are finished, i can't think of a way to find out once the loops are done.

I want to write two nested loops and inside them "two if statements" when I write an Else statement which has a messagebox saying that ID is not found.. it repeated many times depending on the for loops. I only want to be displayed once !!! but when I wrote my code like this (using exit sub), the message appears when the condition is right and appears when the condition is wrong. I tried to move this statement somewhere else but still I have problems with it.
With EMPDataSet
For I = 0 To .Personal.Rows.Count - 1
For j = 0 To .Work.Rows.Count - 1
If EMP_CPR = .Personal.Rows(I).Item("CPR") Then
txtName.Text = .Personal.Rows(I).Item("Full_Name")

I need to create an console application that computes the average monthly rainfall, number of months with above average rainfall, and the number of months with below average rainfall, given the rainfall amounts for each month in a particular year. The program must read in and store in an array the monthly rainfall amounts entered by the user one by one.
So far this is what I have got
Const intMonths As Integer = 11 'Constant Month variable
Dim sngRainfall(intMonths) As Single 'Rain for the month
Dim intCount As Integer ' Loop Counter
Dim sngTotalRainfall, sngAvgRainfall As Single 'Total and Average Rainfall
[Code] .....
How to set this up properly and I am having a real hard time figuring out how to make the data go from this loop to another and add the data to the total.

I was using this old method of creating a bunch of rectangles when I need to get the location of a certain point within a grid so I could draw images on the grid. The thing is, I don't want to use rectangles, I want to be able to just round the location as if I were using rectangles. I need it to be able to round the point (66,70) to (50,50) so if you can imagine a grid and the mouse position being within that square in the grid, I need to get the location of the upper left corner of that square.
