Basic Calculation - Keeping Track Of Total Number Of Discounts

Sep 5, 2009

I am trying to keep track of the total number of discounts given (whole numbers) I keep getting .75 after the first discount, and it adds .75 for every trans action after that. I have tried to pick it apart but I just don't see it. You can follow by tracking the comments that relate to the summary. I know that is an Integer but the book has it declared as a decimal so I went with it.

Public Class BookSaleForm
'Declare module level variables
Private QuantitySumInteger, SaleCountInteger As Integer
Private DIscountSumDecimal, DiscountedPriceSumDecimal As Decimal
Const DISCOUNT_RATE_Decimal As Decimal = 0.15D
[Code] .....

Keeping Track Of Choices?

May 24, 2011

I have two combo boxes, and four buttons. When the user clicks "Add" on the first combo box, it adds a new item to the combo box with "New" and then lets the user rename that item to something else. That "new" item has to have an array of "answers" that go along with that item in the list. What I'm having trouble figuring out is assigning "answers" to the second combobox for each item in the first combobox and changing the second combobox when selecting an item in the first combobox.

EXAMPLE:

Item 1 - Combobox1
- Item 1 - Combobox2
- Item 2 - Combobox2

Keeping Track Of Values In Different Forms?

Feb 10, 2011

I am trying to create a quiz application in Visual Basic 2008. I need to be able to store a score value when the player gets a correct answer. When the value is stored a new question set appears. Once the score is calculated I want to be able to show this is in a new form so the value needs to be passed from one form to the other. I'm not entirely sure how to do this but I believe it will incorporate a module.

VS 2008 Keeping Track Of Ellipses?

Mar 8, 2010

Suppose i want to draw semi-random ellipses on my form.Is there any way i can check if they get clicked at a later stage?Is there any way of storing the location of individual ellipses and then comparing the mouse-click to my list of locations to see if one was clicked?

I can imagine how it could be done with squares or rectangles, but i dont know how to approach it with ellipses.

Im sure this has been asked before, but i've spent a good while searching around for something i can use and came up emptyhanded.

C# - Keeping Track Of Values With Dynamically Created Controls

Jun 14, 2011

I have a WPF application that allows users to create questions of all different types which depending on the type will use a textbox,combobox,checkboxes, or radio buttons to allow the user to answer the question after they build some sort of questionnaire. My question is what is the best way to keep track of the answers across all the different controls after the controls are created and the questionnaire is created on the fly. Right now, i'm looping through all the containers and getting the values based on the controlType.

VS 2010 Keeping Track Of 'Active' Tabpage With Multiple TabControls?

Aug 11, 2010

I am building a sort of 'lightweight' Visual Studio, and I'm trying to implement the feature where you can drag tabs to different 'tab groups', viewing multiple tabs side by side.

I got nearly everything working, I show a ContextMenuStrip when you rightclick the tab headers, with the option of creating a new (horizontal or vertical) Tab Group. When that happens, a new TabControl is added dynamically and the selected tab is moved there. You can drag the tabs around inside a TabControl and even from one to another.

The problem now is keeping track of the 'active' tab. Since I have multiple TabControls (not just two, there can be as many as you want theoretically), their SelectedTab properties are basically useless. How am I to determine which TabControl the user is currently working in? Obviously I will always have multiple selected tabs, but only one active tab, in which the user is currently typing, editing, whatever.I need to know the active tab for obvious reasons: many menu and toolbar items act on the active tab for example. A short explanation of my controls:I have one TabGroupContainer control, which inherits UserControl. I have a TabGroup control, which inherits TabControl.I have a Tab control, which inherits TabPage.

The TabGroupContainer holds a collection of TabGroups (to which I dynamically add/remove TabGroups when required). Now I want the TabGroupContainer control to have the ActiveTab property which returns the one and only active tab (out of possibly many selected tabs).The only logical way is to keep track of the tab that was selected last, for every TabGroup.

At the moment, I am doing this:

- In the TabGroup (TabControl) class, I shadow the SelectedTab property (and return a Tab instead of a TabPage). More importantly, in the property setter, I raise a SelectedTabChanged event:

vb.net
Public Shadows Property SelectedTab As Tab
Get
Return DirectCast(MyBase.SelectedTab, Tab)

[code]....

However, it still doesn't work. I soon figured out why: I am checking that the previously SelectedTab is not the same as the new value in the property setter of the (shadowed) SelectedTab property. I don't raise the event when they were the same, and in this case they were the same (as there is only one tab in the TabGroup!).So, I took that check out, and now it seems to work when I click in the text editor.

So one problem remains: the active tab is not changed when you click on the tab header (and not on the text editor). I am clueless as to how I should handle this... I am once again sure there is a simple fix, but I cannot see it. I can click the tab header, and I'm sure behind the hood it responds to this click, but it never raises it SelectedIndexChanged event because the index didn't change but was set to the same value it already had. I cannot override the SelectedIndex property (so I could skip this check and raise the event anyway even if the value didn't change), and the OnSelectedIndexChanged method is not called, so I cannot use that either...

VS 2008 - The Program Keeping A Running Total?

Dec 9, 2010

I'm about to pull my hair out with this program. I need the following program to keep a running total of the total amount due by a customer for books bought. The exercise required the use of a BookSale class with 3 attributes(a quantity,price,and total due) and 2 behaviors(a default constructor and method that keeps a running total). Here is the code for the class:

[code]...

My problem lies in the program keeping a running total. The total due is displayed fine for each quantity and price but not the whole running total. For example,if I enter 1 as quantity and 2 as price and click the Add to Sale button,the Total Due value,which is $2.00,is displayed. However,if I change the quantity to 2 and price to 4,which comes out to $8.00,the $8.00 is not added to the existing $2.00. I feel like I'm missing something elementary and it's driving me crazy. I would work on it some more but it's already after 4 AM here and I need to get some sleep.BTW,this exercise is from a college textbook. However,this isn't an assignment that is due. I just got bored and decided to work on a chapter we didn't have time to get to.

Keeping A Total - Size Of Pizza Which Is A Combo Box (CmbSize)

Apr 7, 2011

Anyway I am writing a program to allow the user to enter:

-size of pizza which is a combo box (CmbSize)
-type (thin crust or standard) of pizza which is a combo box (CmbType)
-pizza choice (spicy chicken, maryland etc) using a checked listed box (ChkdListChoice)

The problem I have that will probably be simple to a lot of you who are using this language frequently is that I simply want keep a running subtotal of the users choice. So for example the user chooses 8" Spicy Chicken - 3.50, then they press the BtnAddToOrder button to output it to the Textbox (TxtPizzaChoi). When the user adds the next pizza I simply want the previous pizza price to be added to this one giving a new subtotal. I have not made the price change if the user changes the size to 12" spicy chicken, the price is still 3.50, simply because I think this could make it more difficult to me and I don't have lots of time to work on this. My declarations are not all in use and i may not need them by the way.

Heres the code:

Public Class PizzaChoices
Dim price As Decimal
Dim topping As Decimal

Creating A Progress Bar That Runs On Another Thread While Keeping Calculation In Main Thread

Nov 12, 2009

Preface: I know this is an unusual/improper way to do this. I can do this with a "real" ShowDialog(), background worker/thread, and so on. I am trying to do specifically what I describe here, even if it is ugly. If this is impossible for X reason, I have created a fancy progress dialog for some of our long running operations. I need to have this dialog shown on a new thread while having processing continue on the calling (UI in most cases) thread.

Get Files Title & Album Name & Track Number?

Sep 26, 2010

Well I have some music files I want to load up from my program, it is meant to list out all the files album name, song title, track number, etc... it's meant to be a custom player which can load up mp3 files & play them.I can get files to play & everything fine, list out directory it's stored in, full file path & file name & such & extension but stuff like album name, song title, track number, song length I am unable to find out how to get this info.

Previous stuff has showed a way to retrieve them from the file by reading certain bytes & stuff but doesn't work because apparentally the album art is inside the file & at the beginning instead of the other information tags, since such pictures are bigger or smaller at times, I can't simply determine with my current knowledge how to read out the album art either or determine how long of text it would be to skip over, then at that point that the tags are in the place ..maybe there is a way from managed code to do this or API? Reading bytes to determin the info & re-create the album art, and piece together the album name, song title, etc... isn't what I want to do, I want something that's easier to do, I thought it would be simple to make a program just to play some music.

i have a database shown on VB 2008 showing music information. i am trying to show the track with the greatest number of sales however it is only displaying the current information on the screen (i am showing the access database in multiple text boxes) rather than searching the database.

So how do I get the total of num into a textbox? If I type in 3 for "Subject = InputBox("How many")" then I get 3 "num = Val(InputBox("This many"))". Only the last number entered goes into the textbox and they don't add up to make a total.

Find Total Number Of Warnings In Project?

Aug 15, 2011

I've just converted a project from .net 1.1 to 3.5, and I'm being given loads of warnings in the error list. The program compiles and runs ok, but I think I should probably try to at least reduce this large number of warnings.The trouble is that the error list only tells me about the first 102 warnings. Even when I fix one, the number stays at 102. So I have absolutely no idea how many warnings there actually are. If there are 150, I'd like to get rid of them. But if there are 10,000, I don't have the time to fix them all.Is there a way to see the actual total number of warnings?
