View 5 RepliesI started this tutorial on sub procedures and am having trouble trying to get this program to execute properly. The problem lies with the total. I am trying to figure out the math part of it. When I hit F5 I can see this
Item Quantity Price.
Pizza Slices
Fries
Soft Drinks
Total
But I can't get them to add up and display the quantity and price. I tried the ByVal and ByRef code but am not sure if I did it right
Here is the code that I have so far:
Public Class Form1
Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCompute.Click
Dim pizza, fries, drinks, total As Double

View 5 RepliesI need my program to output and input a customer ID and sales amount multiple times. I need it to display both outputs, customer ID and sales amount, on mulltiple lines. It also will need to accumulate the sales amount and then display the total sales. it should look something like that.[code...]
I think that I was supposed to use a messagebox but wrote the program a different way. the form.vb was already locked, but I added two text boxs. Not sure if I did this right because I need to enter multiple sales for one customer ID.[code...]

I'm trying to creat a program that tracks the sales of five products all with different monetary values. I'm trying to display the total number of each product sold, a combined total of products sold, and the total sales value. So far I'm only outputing the value of one of each product, I think there is a problem with the loop somehow. [code]

Assume a grocery store approached you to write a simple program that calculates total sales of purchases. The program should accept item costs as input, calculate the tax on each item (8%), then display the item cost, total cost, and total after taxes. Item costs will be added to a listbox while the total without the taxes will be displayed in a label, the tax amount in another label, and finally, the total cost (items cost + tax) in a third label. this is the problem I have to program for,

I'm currently working on a school project and I have stumbled upon various problems. I'm supposed to write a software tool based on a mathematical model.
In total, the model has 12 parameters and 2 constants used in it, so I figured it would be a good idea to store the parameters in 2 separate arrays - one containing 6 parameters which have to be entered by the user and another one with another 6 parameters which should only be changed in a settings kind of window for tweaking (they are set to default values provided by the model).[code]...

I'm trying to make sure that I don't leave any loose ends open in my application and am concerned about a few but might get my answer from this one. I've "overriden" some functions so that way I can try and keep all the resources as clean and free as possible. So in this instance, I have a function called ExecuteReader which returns a DbDataReader as normal, but all I had to pass to it was a SQL string rather than recreating a DbCommand every time. I want to make sure that even though I'm unable to call dbCommand.Dispose() that it is actually doing so.
[code...]
In here, I set the _dbReader to what I'd get from the function and eventually I close the _dbReader. I do not close the connection as I don't open it each time I make a query. This is a SQLite database that only one user will be using at a time (small application with very very very little likeliness it will grow) so I didn't think it necessary to close and open the connection all the time. Maybe I'm wrong, not sure. Using it this way though, it is potentially ok for cleaning resources?

My code works correctly if I do not have the DO WHILE statement, however we are suppose to have it loop. Which it will continue to ask for the salesman's name, code, etc. but when the user enters the name "eugene" the program is suppose to calculate and output the total monthly sales and the total commission dollars. What is happening is that when a user enters "eugene" the program is not recognizing it to do what it is suppose to do(calculate and output the total monthly sales and the total commission dollars) I am stuck and need assistance on how to make it recognize eugene. I am also having trouble with trying to figure out how once eugene is entered to tell the program to add the salespersoncommission and monthly sales of each case to get the totals to output to the user. Can you add the cases?

View 1 RepliesI was trying to make a program which displays two chars A and B on the screen. Using the WASD keys, it lets you move the A char around and using the arrow keys it lets you move the B char around.
I wrote the following:
Module Module1
Dim Box_A(1), Box_B(1) As Byte
Dim Allow_Draw As Boolean
[Code].....
When I run the program, if I press any of the WASD or arrow keys the corresponding char doesn't move. To make it move, I have to hold down any of its keys for a bit after which I can move the char just by pressing its keys. But then, I have to do the same for the other char.
So, if I want to move B I have to hold any of the arrow keys for a bit. Then I can easily move B just by pressing any arrow key once. Then to move A I have to hold any of the WASD keys for a bit and then I can move A just by pressing any WASD key once.
Is there any way I make make each of the char move just by pressing its ket once?
