ByRef & ByVal Code - Program To Execute Properly - Can't Get Them To Add Up And Display The Quantity And Price

Apr 7, 2010

I 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

Class -program Where Enter The Description, Price, And Quantity Of An Item, Then Click On The Add Button

Aug 13, 2009

I have to create a program where you enter the description, price, and quantity of an item, then click on the Add button. It will then put the description, price, quantity, and total for that line (including tax) in a listbox. The tax is determined by what you put in a text box labeled tax:. When you press Submit Order, it should show a grand total in a text box called Grand Total. It should have a class that is called Items that has a function called GetTotalAmount() that figures out the total including tax. I have started it, but am having a tough time with how to get the subtotals into the text box, then also show the amount including the tax PLUS then do the grand total.

Heres what I have so far:

Mouse Click To Trigger An Event In Another Program Running Simultaneously

Mar 6, 2010

I'm attempting to convert VB 5.0 source code to VB 2008. The converted code will then be slightly altered to facilitate its incorporation into a larger project that I'm developing in VB 2008. After using the conversion wizard (which is actually written for VB 6.0), I have 49 unresolved issues -- less than I expected. Much has changed since the days of my prowess as a programmer (Fortran in the 70's), so working my way through even as few as 49 issues will be a challenge, and will (no doubt) take me a while.

The UI for the VB 5.0 code I'm converting is a "virtual remote," with control buttons that (when clicked) trigger communication to a USB-connected device. With assistance, I've been able to develop my own "virtual remote," contained within my VB 2008 project. Eventually, I will "substitute" mine for the original. For now, though, I'm wanting to use MY "virtual remote" to trigger the original.

I have the executable for the VB 5.0 program, and can run it simultaneously with my "under-development" VB 2008 code. Problem is: I don't know how to cause a "click" on MY virtual remote to trigger a click on the original virtual remote (which is being "monitored" by the other program).

Communications :: Write A Program To Ping Computers On Network To See If They Are Turned On?

Jul 4, 2008

I am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:

Code:

If My.Computer.Network.Ping("192.68.0.5") Then
MsgBox("Computer is on.")
Else
MsgBox("Ping request timed out.")
End If

If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:

A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll

Calculations Using Quantity And Price - Not Getting Right Value

Jun 3, 2011

I got a program I am working on. It does some calculations using quantity and price in such. Heres the calculation module.
Private Sub calculations()
If AdultsizeRadioButton1.Checked = True Then
adulttotaldecimal = quantityinteger * adultpricedecimal * hoursinteger
ElseIf ChildsizeRadioButton2.Checked = True Then
childtotaldecimal = quantityinteger * childpricedecimal * hoursinteger
[Code] .....

Ok, everything has worked when I display the information.... up until the accumprofitdecimal variable. When i display that value its NOT what it should be. For instance i'm putting in a quanity of 1 and an hour of 1 for an adult then for a child, the extended price comes out properly as $2.15 now the code accumprofitdecimal += extendedpricedecimal SHOULD add the extended price (2.15) to the accumulative total. but when i display the accum profit total it shows a number that makes zero sense... is accumprofitdecimal += extendedpricedecimal not correct code?

Varying Quantity And Moving Data From One Table To Another

Nov 21, 2011

Currently I have two tables in a Database (Temp, Main), currently I have four fields in Temp(ID, Qty, LastDate, AddRem), and Three in Main, (ID, Qty, LastDate). I have the program set up to enter in all the information minus AddRem into Temp, then my thought was to either tag the item to remove, or add to the Main table. I'm assuming this could be done by import then update, however every avenue I've attempted has been meet with Exception errors.For the add/remove field it is linked to a Combo Box, which brings me to my other question, how would you link a specific field to say hey if it's this option then add, and if's the other remove?

VB - Calculation - Multiply The Quantity Of An Item By The Price

Mar 12, 2012

I am struggling to write the code for a calculation. The calculation I wish to do is to multiply the quantity of an item by the price. The problem is that the "form" i am creating uses a letter (i.e A, B, C etc) which corresponds to a set value. I do not know how to link the Letter to the corresponding value.

For Example, A= 25, B= 20, C=25

I want to calculate the total of 6 lots of A. I am also using a Combo Box to list the Letters.

VS 2008 Calculate Price * Quantity = Cost?

Mar 3, 2010

I certainly hope I don't aggravate you with what is certainly a very simple code problem. I have never programmed before, but I do have a background in tech support, etc. I have an assignment to do and it's frustrating to wade through the information out there to find exactly what I need and nothing more.The assignment has 3 parts, one of which i've done. We are to do the same function in both javascript and VB. I was able to take a sample we did in class that caluclates a 10% discount and modify it so it calculates the total. Now, I have to modify that into a VB sln file. then write about the differences but that part will be cake.

I am working in Visual Studio 2008 - that program is new to me as well. When I created my login and it asked what VB I'm using, I did not know but under theu of VS, it says VB 2008.hat I attempted to do was to take the instructor's sample discount code and modify it for the new purpose, but an error was generated. This is the sample code I started with:

'Programmer: Dan Dougherty
'Date: Feb 2010

List Name Of All Connected Devices On Lan?

Oct 28, 2010

i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

Add Support For MTP Based Devices?

Apr 3, 2007

I'm writing a media management tool and want to add support for MTP based devices.I've been reading through the SDK docs and with the help of some C# examples have managed to make a start on getting some VB code working.

I've come across a few anomolies that I hope someone can help me with!In the examples IPortableDeviceManager.GetDevice appears in C# to receive a string array. But in VB.NET it appears to only receive a string. I have a similar issue with IPortableDeviceManager.GetDeviceFriendlyName which according to the C# samples appears to receive a char array, whereas in VB.NET it is accepting a UShort.
