Math.min - Find Smallest Number Typed By User In Text Box 1
May 3, 2011
I have two text boxes on my form. text box 1 allows a user to type in a number (decimal) and text box 2 will display the smallest number typed in so far. The idea is to find the smallest number typed in by the user in text box 1, by using the Math.min method to compare each number typed in by the user to a variable that contains the smallest number to the point. Then replace the variable value with the smaller of the two numbers. To make it work for the first number. I have to initialize the variable to 99999. (no if else statements should be used).

well i am having a couple of issues with this particular homework problem and this is my first programming class so there is probably quite a few mistakes well the homework problem is to take three double values entered by a user and display the largest and smallest using math.max and math.min and display the smallest and largest so i thought i could use a listbox and take the values that went to the listbox and assign variables to each so i can try to use each variable in the math.max and min but im not making it to far and i actually might be way off

Getting largest and smallest number from an array and placing in 2 dif Posted 02 November 2010 - 05:34 PM I have the code written for everything except when I try to display the highest and smallest numbers from the array into a label it display 0 for both the smallest and highest number.Question: Create an application that lets the user enter 10 values into an array. The application should display the largest and smallest values stored in the array.
*The form is a list box with 2 labels and a button to retrieve the 10 numbers and put them in the list box then the other button puts the highest and lowest number in the 2 labels
Note: Place them in 2 diff sub-routines.

Option Explicit On

I have an array called linedistancearray.I am now trying to find the smallest integer in that array and store it another variable called mindistance..The following is my initial idea: I sort the array and then pick the integer with index 0. Array.Sort(linedistancearray)However what I get is the first item being a 0 not the smallest integer value in the array I need. HOWEVER if I choose the index 1 it works.So what I was thinking was a way to remove all 0s in the array. I am not concerned about the order of the items at all all I am looking for is the smallest integer in the array.

I'm making a program for a class, as usual. I need it to grab the smallest number, of the 2 inputted numbers.Well, there is 4 inputted numbers. For instance the user inputs the following:
Price Ounces
20 4
12 4
I divide the numbers, and get 5 and 3.The better buy is going to be item 2, as it is $3 per ounce.But I need the program to grab the smallest number AFTER dividing, and then display that in a label. I need to know how to grab the smallest number. What statement do I use?Odds are, it's something simple and I'm overlooking it.

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.

So I wanted to make a program for math where you enter a number into a box. Then you click enter. The program has numbers 1-12 next to a check box. If you click enter it divides your number by the numbers 1-12. Let's say you put 100 in that box. Then you clicked enter. The check box next to ten would be checked, 4, 2, and 5 would all be checked because those numbers evenly go into 100. How can I have the vb check to see if the sum is a whole number?

Am using VB 2005 and need to take an existing txt file which basically has 15 sets of data, each set containing a year (ie Year 1990) and a number below the year.
When a user clicks the calculate button on a form, I need it to first list the average of all those numbers in the txt. And below that I need the largest number in the file to be displayed.
I am basically familiar with using objReader and StreamReader. But, I can only verify and open the text.

I'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.

Ok, now I have another problem that I cant seem to figure out I now have the "Labour charge section" just incase the service requires one. which in alot of cases it does. So, I have a test box called text box 1, which I want to be able to insert "hours worked" which is a "digit" and then Have a fixed value, of five. Which the user can later change. The number from the box, and the user specified Hourly charge, must then be multiplied to create the total labour charge which will be inserted into a label view. So, my question first, is, how would the user be able to set the hourly charge and then not be able to change it by accident. I was thinking of having a tool strip with an options tab and then setting, and then you use that to fill the info, and have that hourly charge, hidden of the actuall form so that it cant be changed by mistake. Then, on to of that, how would you multiply these two numbers?

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.

I have a Windows vb.net project that does an occasional "auto refresh" based on a 20 minute timer. I want to avoid any type of auto-refresh... if the user has manually had any interaction with the program (mouse move, click, keystroke, anything) in the past 5 minutes.
I added a global variable "Dim g_LastActivity As Date" so the timer can detect that 5 minute mark.
Is there some place to put my "g_LastActivity = NOW" line that will ensure it will happen during ANY user activity? All mouse clicks, on all buttons, all mouse moves, anywhere, all keystrokes, basically EVERYTHING.
