Adding Numbers From A Datagridview?
Feb 17, 2012
I have a datagridview named Partcotdatagridview. In this datagridview, I have two columns. The first column has a combo box with some names in the data source such as John, David, Alex. The second column is designated for amounts. Each person will have different entries in the datagrid I will select a name and enter an amount for that person. I would like to display the total for each person in 3 different labels in a different form.

ok the problem is that when a button is click I want it to add 1 (+1) to a textbox. This process will keep on going on till I tell it not to...How would I just keep a running total of whats happening in the textbox...What I mean to say is that if I pressed the button 10 times, instead of it showing:111111111 I want it to automatically add the numbers up to show 10 instead.

i have the following piece of code: txtGrandTotal.Text = Val(textbox1.Text) + Val(textbox2.Text) + Val(textbox3.Text) If the numbers entered into textboxes1,2 and 3 are positive integers it all works fine, but if for example the following happens i get unexpected results textbox1 has the number 3, textbox2 has -1 and textbox3 has 6. I expect the result to be 8 (3-1=2 + 6) = 8 Instead I get 14. I understand the concept of precedent but how do I set it if I don't know if the number entered into textbox is positive or negative?

I'm making a program as part of a college assignment that requires my to add up the contents of an array. Now the array has 20 places, and the only method I know of atm is:a + b + c + d + e etc...They are all different numbers so I can't just do a * 20, I need a more code efficient way of adding all these numbers up, is this possible?

I have a text file (*.txt) with a name in each line, like this:
Joe
Dane
Lisa
Kelly
Now I want each name added with a number from 1 to 99.
Like this:
Joe0
Joe1
Joe2
[code]....
I have folowing code:
For n As Integer = 0 To (numbernames) - 1
strContents = objReader.ReadLine()
For i As Integer = 0 To 100 - 1
[code]....
With this code all happens ok and a new text file is created with the desired name-list with added numbers.The only problem is that the last name doesn't get a number added from 0 till 99 but for example 0 till 17.

I'm trying to add certain numbers together from a textbox full of numbers from 1 to 10. This is my
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub[code]....
When the button is clicked, it gathers the list of numbers from the test.txt file and displays it in the textbox. Now what I want to do is make a label so that after it streams the data and displays it in it's multi-line text box, is for every 10 and 1 displayed on one line, it will subtract 1 from the number in the label. For every 2,3,4,5,6 I want it to add 1. For every 7,8,9 it will not add anything.For those who can tell I'm a blackjack fan and I was curious on how to keep a running count in a label from a multi line list of numbers.

I am trying to add up numbers in a listbox.I know how to add them up and make them display on a messagebox but what I cant do is add the numbers in one listbox and then add the numbers in another listbox and subtract the total of the numbers from 2nd listbox from the total of the 1st BUT instead of displaying them on a message box how would I output those results into a label?This is the code I have for outputting the totals of a listbox onto a message box:
------------
Dim intTotal As Integer = 0 'Running
Dim intX As Integer = 0 ' Index Position
For intX = 0 To lstDebitsBalance.Items.Count - 1
[code]....
btw the name of the second listbox I want to sum up is lstCreditsBalance

I have a Repeater... And it has a Weight field. the weight it displayed in a textbox. I have this piece of code:
lblTotalWeightCalc.Text += NewDV.Item(i)("Weight")
This will get the Weight and display it in my label. But when I select more than one item (which will have two weights) it will show: For Example:
Item #1 : Weight = 20
Item #2: Weight= 50
The total Weight= 2050 (it doesn't add them together) I need them to be added together....

I have an issue in VB6 that is giving me a major headache. When using a variable defined as a single data type, VB6 will add random numbers to the number i assign to it.
For instance I have a single variable that is manually set to 0.3. Then i create another single variable and set it to 0.25. I have the program add 0.01 to the second variable until it equals the first. But they never equal. I couldn't figure out why when both were showing they equaled 0.3.

I have a datagridview with a column called "Total Price". This is set to a string value type because I need to always show 2 decimals. For example:
4,3
must be in the datagridviewcolumn:
4,30
So I use string.format for this. However, now I have a problem with sorting because the column is a string value type and numbers get sorted like this:
50
4000
40
300
30
20
10000

I have a DataGridView1 where I have 6 columns and 0 rows (they are added additionaly in the application) and also have a TextBox1. How can I calculate all data from the second column to the TextBox1? For example, I'll run the application and add rows, where the text in the second column will be: (4, 8, 9, 1)... it means 4 rows...
So how can I make the value of those numbers (22) show in the TextBox1, so that it will calculate the numbers and show the sum in the TextBox1?

I using vb.net vs2008.
I have a datagridview and two datatables. I am comparing the information in the two datatables. Now, if the data exists is datatable2 but does not exist in datatable 1 I would like to add a row to the bottom of the datagridview and fill in the necessary information.
Can someone give me an idea of the necessary syntax that I will need to accomplish this goal? Also, I know this post is a little vague and if more information is needed to answer the problem I can give it.

I would like to add a row into a DataGridView: The first column is a string All of the middle columns are of integer type (for sorting) The last column is a string All the values above are passed to the Sub by a array (currentRow) of type String. However, the middle values have to a go through a type change to type Integer for sorting The following Sub works perfect except: The number of items in currentRow (the columns) may vary Then the hardcoded dgProduction.Rows.Add() code at the bottom with not work properly because it is fixed with a total of 6 columns. note that the length of currentRow() will not vary during the population of a single population event. Instead it may vary once I have cleared the grid and click on a different date. So all the rows within the grid will have the same number of columns.

I have a DataGridView that is bound to a DataTable. In this DataTable is a column that contains an image path location, ie; c:imagesmoon.jpg. In the DGV, I'm only displaying 2 columns, the "Name" of the image and the "Image" itself, which basically is the path information. how do I get the image to display in DGV Column? Because even though it's bound...no data comes up when I run the app.

I am trying to add and update data in a db from a DataGridView. I have a save button that runs this code. The code works fine. It figures out which rows are new and add it into the DB and which rows are updated and updates them in the DB. BUT if you press the button again it will add the new row in again. it does not mark the new row as one that needs updating when the button is pressed again
