I have 10 Numericupdown boxes in my Form from numericupdown1 to numericupdown10. I would like to instantly display the total amount of all ten numericupdown in a Textbox (textbox1) on the form. I don't want to have to push a button to get the total value of the numericupdown boxes.
is there any way to populate a listbox with totals data from previous pages? I'm working on a project for a class where the final form needs to have all the totals from the previous 3 pages (each page has one total each), in some capacity (so I do not necessarily need to use a listbox if there is an easier way to do this).One thing about the previous 3 forms, two are set up in radiobuttons and one is set up w/a checkbox format (but I will likely change the radiobuttons over to checkboxes as a later revision).I just can't figure out how to populate the listbox with info from a previous form, I keep thinking load events, but that doesn't take into account which options might be taken from previous forms.once the totals from the previous forms have been added to the final form I will need to add a 7% sales tax. I assume that something such an if then statement will take care of that though.Just wanted to run that everyone here at the forum just in case there is a better way to do that.
I am attempting to complete an assignment for my Intro VB class and it is giving me a good bit of grief.
The assignment calls for at least 8 checkboxes with corresponding labels and one more label displaying the total amount due. I know that I am supposed to declare a form wide variable and then add/subtract from the variable within the even for the checkbox being checked.
I get the appropriate amounts to show in the corresponding labels but they wont add in the total due label.
We are using VB.NET 2010 with Crystal Reports to generate reports for our project. The reports are filled from Data Sets that are filled from Arrays. As far as that goes all is working great.Where we are running into a headache is when we try to total up a specific column in the generated report. We have created a Group called EMPLOYEE that creates grouping by employee name. We cannot seem to figure out the necessary steps to get our AMOUNT column (Numerical field) to total in the EMPLOYEE group or anywhere else for that matter. No luck with Google (may not know what to look for...) no luck here and no luck with my CR book...
i have a listbox, that i want to make sure the value im about to add to it, is not already in the list, here is what i have but it dosent put anything in the list box.

I am wanting to allow a user to enter a number and depending on what number is entered, it will allow that many entries. For example, if 5 is entered, the user has to enter 5 numbers. Those 5 numbers will then be added together.I 6 is entered, 6 total numbers will be added.I was trying to do this with a for next loop but I wasn't getting anywhere.

I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?
I am attempting to read the results from a SQL query into a List(Of) and I can see the List.count while adding items to the List increments, however in another part of my code when I am attempting to read the List the List.Count returns 0. My List is as follows:
I have a class that has a property that I declare like this:

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]
I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?
I have an assignment to create a website that people can use to make dinner reservations. We are using Visual Basic code for the forms. It's supposed to keep running totals of each type of dinner. I'm having trouble getting the running totals to not reset to zero. I have them declared outside of the button click event. Not sure where I went wrong. Here's the code:

I have yet another question. I have set up a series of radioButtons to create a menu of choice for a class project and am trying to set it up so that there would hypothetically be a discount on a purchase of two or more t-shirts, I have the coding set up so that if any one item is checked and the calculate button is clicked, then the dollar value or "total" will show up, however I am not able to set up a total for more that one item, it clears the previous "total" and sets up a new total for the most recent t-shirt value checked.
Can anyone possibly take a look at my code (below) and tell me what I'm doing wrong? I have been sitting here for hours trying to figure it out. I'm very new at this and I'm thoroughly confused. I am using a book for Visual Studio "Programming in Visual Basic" and I have gone through all of the tutorials and code examples and followed them exactly (at least as far as I can tell). However, whenever I run the program, I am not getting the sum of the quantities I assigned to the constants showing up in"AccessoriesTxtBx" as I'm trying to. It shows up as $0.00 even when I have checked the boxes.[code]
How would you take a numerical input from 10 text boxes and total it up and send it to a label. Then average the 10 numeric text boxes and send it to its own label. I am not asking for any code, I just need a hint or two to jog my memory. If this is not clear for you, I'll provide more detail.
An ADOX (Access) database has five columns. ID, Date, Category, Store, Amount paid.It is possible to specify ten different items in the Category column: Apples, Oranges, etc.
I am very new to Visual basic. I don't know if I even have everything in the correct order. Here's my problem. I am trying to take user input on 3 input boxes, get discount from select case and then calculate out the following. My problem is I can get the code to do a simple addition, but If I try to do any calculation at all calling the discount I get an error where the output totals to zero. I don't know if I am missing something associated with the sub getDiscount() or if there is a problem elsewhere.Ultimately this is what I want my calculation to end up as.
First calculation Price * Entered Input * Discount = Full Discount Value Second Calculation Price * Entered Value - Full Discount Value = Total
I've been working on a class project for quite a while, and I have not been able to figure out this step on my own. What I'm trying to do is connect the totals from three forms to a fourth page where I can then tally to those totals and then add 7% sales tax on the final total on the last page (I don't think I'll have a problem with the final part of add the 7% sales tax, but I'm not completely certain how to go about moving the totals through to that final form. Also, some of my forms use radiobuttons and one uses checkmark controls. I'm going to show some of the code that I have for each page in case this will make a difference. I think I need to do something with a public variable, but I'm not sure how to title that variable, and the public variable should have sub variable sections in each form, or if one specific public variable should be placed at the beginning of each form.I had also considering using a module to connect the totals in the forms together, because someone had suggested this, but I am not familiar at all with this method.

this place looks pretty reliable and helpful so i thought i'd give it a shot.anyway, i'm a student looking for help. i have to write a program that calculates costs for a catering company. i have that part down, but whats stumping me is that i have to make a summary button that adds everything up into a grand total from the previous calculations and display it in a message box. displaying and calculations aren't really my issues, but getting the data to calculate is.
i have an idea of what to do i just don't know how to go about it. i know i have to store the data somewhere, but i dont' know how to keep adding it up so i can get a grand total, so i'm thinkin there needs to be something there to count.

I get an error when i try to add the Array TempArray to the List of Boolean TruthBool... The Error Says QuoteObject reference not set to an instance of an object.The Variables are declared like this
Dim TruthBool As List(Of Boolean) Dim TempArray(10000) As Boolean
I know there are a couple of other problems with this code.. and i have solved most of them in my actual program.. I just cant get this error to go away...
I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.
It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]

Everything in my program is working correctly so far. The only problem I have is trying to update my totals for the program. I need to show total sales, total pay, and total commission for the program by using the file and then summary key. How the program works is that you get a base pay of $250 and you get a commission rate of .15 if you reach 1000 sales. I have done running totals before but not for one with multiple functions.
