The first would be, how would I go about making each index in a list box an integer or decimal value? For example, If I wanted the 1st (or 0) index to = 300 and the next one (1) = 400. The next question that I have is that, if I had two or more list boxes with each index as a certain value as listed above, how would I go about adding up the total for each index that is selected?
View 10 RepliesI'm new to forums as well as new to VB 2008. I'm in process of making a order calculator which will total any values you selected in combo boxes/checkboxes and then display it in a selected area. There are 3 things that I want to achieve: 1. Be able to add another total to an existing total (currently I'm able to see only one total when I hit "Calculate" button)2. Display how many orders I have made so far (new total counts as one order)3. Be able to add up checkboxes selected to an overall total. (when I try to add up one checkbox with another it seems to be stuck on 1.5 pounds which I assigned for each "side order")

View 6 RepliesIm having a bit of trouble with my program. I have a few items that are selected by checkbox to add to a Textbox but the problem Im having is if I dont uncheck the textbox the checkboxes just make the total keep adding up. So if I have an item selected and I want to add another one by clicking its checkbox it adds the other ones to the total again and thats not what I want to do.

so i need to make a program that adds the values between 1-100 to total up to 5050 but with that being said im not sure how i would code that. since its supposed to add all the numbers from 1-100 like 1 + 2+3+4+5+6+7+8+9+10= 55 and im supposed to make the program do that until 100
View 33 RepliesI'm having some major issues with this little booger. I will supply what I've tried, but let me explain what it should do first.
Upon the text change event, if the item number is found in the DB, it should add it to the list. Then, take the 7th sub item, and place it on a label. Each time a new item is added, the cost's should add together to give me a total. Simple enough right ?
CODE:
This is a huge mess, I'm very tired and not real sure how to do it. But the item is adding twice for some reason, sometimes after I've added it one time (appears twice) and add it again, it might add 4 times, or 5. And when two items are in there, the cost displayed on lblPrice is 4x as much as it should be. Can anyone point out where I'm all screwed up, and maybe suggest a different way to go about it ?

View 1 RepliesI loaded up a checkedListBox with items form a .txt file. The .txt file has itemName, ItemPrice. Every item that gets checked shows up in a listBox on another form. The problem that I am having though is that I need to accumulate the itemPrices of the selected items to show up in a textBox, but the only price that shows up is the price of the item in the checkedListBox that has the focus. I'll add the code to this:
Public Class Form3
'define the Product structure
Structure Product
Public itemName As String
Public itemPrice As Decimal

i have a problem about adding up the sum of table in my listview, [code]after i input a value in the textbox1 it will give me the total amount in the listview items. the problem is i cannot sum up the table amount which i will be needing to proceed to another transactions.
View 1 RepliesI have four forms only. The first one is the main menu, that contains three buttons, the first and second buttons go to form2 and form3;Button 3 should open a new form (4) and to write there just the total price.
In Form2: DataGrideView that contains a table made by MS Access 2007. That table contains only two columns and three rows. When you select the item, the price of that item should be saved to be added to the other selected items
In Form3: ComboBox that contains another table also made by Access2007. The same thing, the table contains two columns and the selected item has a price that should be summed with the first selection in Form2.
My Questions are:
1. What I did by adding data from MSAccess2007, is it right?First: View -> server explorer -> Browse(my database) -> Test Connection --> OK ...Second: Data Sources --> Add new database --> etc Third: I dragged one table and put it inside Form2, then the another table to Form3.Is that all right? <--- This is my first question.
2. Now, is, what I have done in step 1, enough to pick up the price of the selected item(s)?if not, what is the code that I have to write to make this connection, and where?
3. As I said, when I click on Button3 in Form1, Form4 should appear and give me the grand total. How I can write a code that makes this summation, and where?
I have a class project that I have been working on for a while, and I can't figure out how to add each cost from lstCosts together to show a total cost of the selected workshops in lblTotalCost. Using the current loop that I have, it only adds the last cost in lstCosts. Is there a way to add the indexes together?
Code:
Public Class Form1
' The registration fee for each workshop
Const intSTRESS As Integer = 595 ' handling stress
Const intMANAGEMENT As Integer = 695 ' time management
Const intSKILLS As Integer = 995 ' supervision skills

I have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.
