Get Totals From Forms (1-3) To Appear On A 4th Form?
May 1, 2009
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.

I'm taking my first (and only) beginning programing class for Visual Basics 2008. I'm working on my final project and have hit a snag. A little background info - I have been able to code everything except for two final steps (but they are my most difficult steps), on these final steps I've gotten two suggestions on other sites, one person helped me with the coding which I used for my form1, but it I still have several errors, and another person suggested that I use a module.
Here is the issue. I have totals on three forms that need to pass through to a final form, and once they are on the final form they need to show up in an itemized list and need to then be totaled again. I actually have a total of 5 forms including my first form aptly named form1, which incidentally is where someone told me I should set up my whole 'connecting the totals' form, and I believe the guy was on the right path with helping me but, I'm still obviously pretty lost on this last segment of coding. Since I had little difficulty with the majority of my project, I didn't think this last bit would be so difficult. I'm going to list my coding for each form below. My project is due Tue morning May 5th Eastern Standard Time, just in case someone starts reading this on or after that date. Just in case it helps explain the issue, I will also post my listing of error codes from my VB project, and they all are centered around my form1 (which is the form that I'm trying to set up the transfer through of the form totals). I also see that I can post attachments so in case it will help I'm going to post my project in the attachment too.
Error Codes:
Error1Event 'Load' cannot be found.
Error2Handles clause requires a WithEvents variable defined in the containing type or one of its base types.

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.

How do I fire an event when changes are made in a datagrid embedded in my form? My datagrid houses line items for different forms (Sales Orders, Purchases Orders, etc.), and when a value is changed (i.e. quantity or price), I want it to re-calculate the datagrid automatically (extended amount) and also re-calculate totals in the form itself without having to hit the Save Button. Right now I have a sub-routine that fires when the button is chosen, but how do I fire this event automatically on datagrid changes?

I'm relatively new to VB programming & My question was, how do you see the control source or rowsource of a text box so that you can make I display data. I have a case where I am trying to display sub-totals from an exce spreadsheet into a text-box on a User-form. And is it possible to make a selection in one listbox and have corresponding selection highlighted in another listbox?

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:
Option Strict On
Partial Class _Default

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.

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.

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

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.

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.
Option Strict On
Public Class CommissionForm
Const QuotaInteger As Integer = 1000
Const BASEPAYInteger As Integer = 250
Const COMMISSIONRATEDecimal As Decimal = 0.15D

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.

I am creating pivot tables in VB.NET and have run into a problem I did not think would be as difficult as it is turning out. When I create a pivot table it adds in subtotals for each row and I do not want that. In excel you just drag down the subtotals option and tell it to not display subtotals. I looked into the VBA for it and it is several lines long of this format:
ActiveSheet.PivotTables("Main Highway Pivot").PivotFields("Division"). _
Subtotals = Array(False, False, False, False, False, False, False, False, False, False, _

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 the age old scenario where I have parent child related data. The child data contains many records with a cost field that goes into making the total cost on the parent record.
Is it good/bad practice to store the totals in the lines and also the summed total in the header?
The system will require that the child records be manipulated and therefore, the summed total will change. I also have a requirement where the summed total will need to be calculated and displayed on several forms and reports. I am able to code the system either way just wanted peoples opinion.

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 have a form being called form several forms using ShowDialog().
1. Is there a way for called form to know which form called it by receiving a code or key from the calling form?
2. The calling form has a gridview. How can the called form pick up a column's value from the currently highlighted row in gridview in the calling form?
