Create Asterisk Square Using For Loops?
Oct 26, 2010
I'm having a little trouble with this assignment for my 1341 Fundamentals class...A copy of the assignment can be found here. The section I'm having trouble with right now is as follows:
Quote:
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

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".

Im using Visual Basic 2005."Devise a program to create a multiplication square for any size the user enters, up to a maximum of 10x10. The program should output something like this for a 4x4 square.
1234
2468
36912
481216
You will need to make use of the RichTextBox, along with concatenation to make the output format correctly within the box.When you have created the working program, document it properly by printing out and annotating the code to explain how it works."

Trying to create a program that accepts a square array size 4 by 4. Then it should print the totals of the rows and columns. I started with a form and made text boxes and created a print button. I made it so that numbers can be input into the boxes. When hitting the print button, it should print the totals of what was input, however, it isn't doing that. Is there a different way to write the array code so that it will print it? Should i not have text boxes but rather have labels with fixed numbers set in them?

create an XML file from a large Oracle dataset. The Oracle dataset contains an ID column and a bunch of different address types. For example, An ID will contain a primary address, secondary address, and a bill to address. Each of the three address types can have multiple addresses but I'm only retrieving the first three.Currently, I'm retrieving three of each address type then joining all of the data together. If I continue with this method, I would have to loop thru the dataset to find the ID and then loop thru the dataset again to find each address for each address type. This doesn't seem very efficient and I'm wondering if there is a better way to do this. Is there a better way to manage the data on the oracle side so that I can have one row for each ID? Or is there a better way to handle this on the .net side with collections and manipulating datasets?

I have some existing code that looks something like this:
[tag:cb cbid="12345" cbwidth="200" cbclassname="calloutbox" cbposition="left"] Lorem ipsum dolor sit amet, consectetur adipiscing elit.
[tag:cb cbid="123" cbwidth="200" cbclass="calloutbox2" cbposition="left"] Suspendisse eleifend enim a magna pretium porttitor.
I need to write a VB .Net global function that will match these [tag:cb] and take the optional parameters and rewrite the string with Html tags.
<div id="12345" width="200" class="calloutbox" position="left">content (based on id)</div>

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

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

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

But now when i reopen the VS.NET 2008 solution, change something, rebuild --> the assembly-version info did NOT change. Even closing vs.NET 2008 an reopen, change, rebuild --> still no changes in the assembly-version...Why doesn't work this anymore (It still works in a C# project) ?

When I click on my hard-coded richtextbox, I need my cursor to be like a square so that it replaces the text with the user defined text. How would I go about doing this? Here's the dode:
<
Dim strTab
As
String = _[code]....
\
Now when a user selects a "-" I need the cursor to be a square so it can replace the "-" with the user input...lets say a "5".

NOTE: Picsource is just a PictureBox named that way. If I put "BrushSquare.SurroundColors = Color.Red" in a comment. The program works but the edges are white, not red like I want them to be.

I need to take a minimum and maximum value from the user for length and width using an array(s) and display the square feet of all values. Since the values can be any number the array(s) size cannot be defined. In my form I have 4 text boxes (MinWidthTextBox, MaxWidthTextBox, MinLengthTextBox, MaxLengthTextBox). I have been able to take the text from each text box and initialize 2 separate arrays with those values, however I am completely lost on how to get the square feet from each element. In other words I don't know how to do this:
WidthArray(0) * LengthArray(0)
WidthArray(1) * LengthArray(1)
WidthArray(2) * LengthArray(2) etc. etc.
I don't know if that is possible or if I am over complicating things.
Here is the code I used for my arrays:
Dim WidthArray() As Integer
Dim LengthArray() As Integer
Dim MinWidthInteger, MaxWidthInteger, MinLengthInteger, MaxLengthInteger,
[Code]......
In each For loop I can output the elements to a listbox for text and it works but again I have no idea how to multiply each element to one another to get square feet. Should I be using a multidimension array instead?

I have a picture that is the map of a circuit [URL]. Now I want a Square to follow that circuit. I have tried some things but I couldn't get it right. How would you start? And how do you access the color values of the "line" to follow it with the square? Or is that even the wrong way to do it?

I was wondering if it was possible to somehow use (or import if I have to) the square buttons that you sometimes see as the default System button on older Windows computers, and use it instead of the new Windows XP rounded kind with the white background.
I tried looking here to simply make the square button myself: [URL]But it makes 0 sense to me.Also I don't want Flatstyle as it makes the button 2D and I want the old square but 3D buttons, like the OK and Display button in this picture.[URL]
