I have an assignment to make a multiplication table using loops. The idea is to make this: If the user enters 3 this is the result he gets:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
if the user enters 5, this is te result:
0 1 2 3 4 5
1 1 2 3 4 5
2 2 4 6 8 10
3 3 6 9 12 15
4 4 8 12 16 20
5 5 10 15 20 25

The only problem with the code is that it displays only the integers 1 , 4, 9, and 16 when ran.

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.

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

I am very new VB .NET and just starting If statements. My problem is: Write an If statement that determines whether the variable CurrentBalance is greater then 1000.01. If it is, multiply the variable CurrentBalance by 1.005. Otherwise, multiply CurrentBalance by 1.007.So far I have
Sub Main()
Dim currentBalance As Boolean
System.Console.WriteLine("Enter Current Balance: " & currentBalance)
If CDbl(currentBalance) > 1000.01 Then

I really don't even know if thats how I should be starting. Not sure what to put after the first Then on how to make it multiply currentBalance by 100.5.
This is part of a calculator program. I first part I sort by num and sign using a multitude of commandbuttons with no parenthesis.This program below is part of the second part. I have three more subroutines for /, +,- respectively.The + and - work correctly but * and / do not.I think it is in the line: numop(m) = g * h Is there something I am doing wrong wth the syntax in multiplication?
Public str, sign(100), numstr(100) As String
Public num1lock(100), m, n As Integer
Public ans, num(100), numop(100), g, h As Long

How do I multiply inside loop using this code ?
Dim a As Integer
Dim b As Integer
a = inputBox("Enter first Number:")
b = inputBox("Enter second Number:")
and I want the answer to be shown in a label.
I'm new to VB and programming in general and have not had too much trouble however i cannot figure this problem out and i've been working on it for a week. basically i have to create a program that calculates the mass of someone on another planet with the conversion numbers as constant, an input box for the user's mass, using select case format and output to a label including the name of planet ie "Your mass on &strPlantet is x" so what happens is my intWeight variable becomes zero and the lblResult is Zero. (i have not added the all the code for the label output) oh yeah i must also use a try/catch structure to prevent non numeric data from being input.[code]

Simple Calculator multiplication and division Trying to make a simple calculator. My program inputs numbers and arithmetic operations thru commandbuttons. The numbers, num(n-+1), are odd and the operations, op(n), are even. The code is based on the even op string. Every time a op occurs it is stored in numop(n) to be accessed later. I have all the other operations in sequential order: "*"," "/, "+" and "-". The other similar For-Next loop are the same just interchange the two * for /, +and -. The "+" and "-" work fine in this configuration.
My problem is the multiplication and division does not occur. The numbers and operations line up. The numop(m)=g*h should yield numop(m)=num(1)*num(3). Is there some sort of code to be inserted to accomplish these multiplication and division operations?

I want to open an Access database and I want to multiply 2 fields between each other. I am a newbie and till now I only have found the way to open the access database and create my Recordsets. So, for example, if I have table Mytbl that is a recordset with 4 fields (columns) and I would like to multiply column 3 with column 4 and put the results in a new Recordset, do I have to do it by multiplying each and every record
View 4 RepliesI have some combo boxes that basically set labels and scale multiplication factors for an XY grid. The combo boxes themselves work as they should. Two adjust scale levels of the XY grid (label and multiplication factors) the other changes the Y axis units (Imperial/Metric). The issue comes when I try to replot old data... I have the data in the array and have confirmed it is accurate...but...
When I apply the appropriate value to combobox.selectedindex and then call the Sub that actually makes the scale changes, the selected index reverts to -1. Small Example.... (note consider all variables as public and all routines in a single class - ignore spelling - this is a quick subset recreation not a copy).
Private Sub ReloadGraph()
combobox1.selectedindex = LengthScale(GraphNumber)
Call LengthLabels()
PlotUnits = Units(GraphNumber)
Call UnitsSet()
[Code] .....
OK - so I did add some code..... I did not actually run this code, but this is essentially a snapshot of what fails....when I step through line by line, the selectedindex changes to -1 as soon as I step to the second line of the second 2 Subs BEFORE it processes the second line (i.e. always after I step off Private Sub xxx() ). Again, both UnitSet and LengthLabels work OK separately when called, it is ONLY when I set the selectedindex from a variable (and again, it DOES set OK) and then call these routines that the selectedindex goes to -1. I have read a bunch of stuff relating to selectedindex and selectedvalue resetting IF one or the other is blank, but I have tried setting both in testing and this fails too!!
I have made an countdown app that is working in a normal way (added picture of it). Now when I select a number in the numeric box and click start, it starts to count down from that many minutes, but what I want is the number I put in the box *3. So if I put in 3 (points) the counter will count down 9 minutes. If it is possible I want a counter at the bottom every 3 minutes the value of the 000 at the bottom of the image multiply by 1 (+1 for every 3 mins timer1 runs).

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."
