Finding Area And Perimeter Of A Rectangle?
Sep 8, 2009OK, so I just started this VB programming class at school. But I don't understand much because the teacher doesn't really teach us. He just types everything on the projector and expects us to keep up. We have this project in which we are supposed to build a form that accepts the length and width of a rectangle, and calculates the area and perimeter of the rectangle. CAN SOMEBODY PLEASE HELP ME?? I really have no clue how to do this, and more than half the other people in our class don't either, so finding help within the class is pretty much out of the question.
The user enters values for the length and width of a rectangle and clicks the Calculate button or presses the Enter key to activate that button. The application then displays the area and perimeter of the rectangle in the third and fourth labels on the right side of the form.
Specifications The formula for calculating the area is width * length. The formula for calculating the perimeter is 2 * width + 2 * length. The application should accept fractional decimal entries like 10.5 and 20.65. Assume that the user will enter valid numeric data for the length and width.

Sep 19, 2011I need to create a simple program that will calculate de price of the meal+the taxes aswell as the tip.
The prov taxe= 8,5%
the fed taxe = 8%
and the tip is 15%

Private Sub partie4_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles partie4.Click
Dim repas As String
Dim sous_total As String
[code]....
The user has to type the price of the meal and then it should calculate the price but for some reason instead of *8,5% it will do x*8.5.

Oct 19, 2011I am trying to calculate the difference between 2 times.
So far I have 4 labels.
Label1 = Current date and time.
Label2 = Contains the exact time that the application was last closed.
Label3 = Contains the exact time that the application was opened.
Label4 = I want this label to say how much time in seconds had elapsed between the application last being closed and the application being opened again, in other words the difference in seconds between label 2 and label 3.
Below is what I have done so far, but despite repeated efforts I can't seem to find a way of getting the time difference to show in label 4?

View 4 RepliesPoint Inside A Triangle Or Not
Mar 10, 2009i was asked to do a program which can find if a 2d point is inside a triangle or not, only the 3 points of the triangle were given. i planned to do this using the slopes of the 3 sides, then with y-y1=m(x-x1) using the other vertex and the point being checked see if the slope was the same sign and on the same side of the line. if this was true for all 3 then the point is inside the triangle the problem is i cant think of a logical expression for the if/then/else structure to show this anyone know what i should use or should i just go down a completely different route?
