This is are the parts of my system where my problem occurs: - Search Button - List Box1 - TotalTextbox - Button - SQL Database with a Column named "Amount" and it only contains numbers Datatype is System.String
So, basically a user clicks the Search button and searches for a data in the SQL Database, and the result of the search displays in different Listboxes including the "Amount" Column from the database, which has it's own Listbox named "Listbox1". the Listbox is now filled with numbers.
Goal: The goal is to get the Sum of all the "Numbers" Displayed in the Listbox1, and the Total is then Displayed into a Textbox via using Click event or automatically.
The Code:
Dim sum As Double For x As Integer = 0 To ListBox1.Items.Count - 1 sum += CDbl(ListBox1.Items(x)) Next TotalTextBox.Text = sum.ToString
And i got this Error: Conversion from type 'DataRowView' to type 'Double' is not valid.
I ended up with this..
Dim sum As Double For x As Integer = 0 To ListBox1.Items.Count - 1 sum += Val(ListBox1.Items.Item(x).ToString) Next TotalTextBox.Text = sum.ToString
But the values are not adding up, the total is always at 0. i've been searching for hours now from the net to a better way of doing this.
Here's a quick Flow on what im trying to accomplish here. Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
I'm having a problem with my software. Im totally new to Vb.net and only learning through ebooks and google.This is are the parts of my system where my problem occurs:

I have a form where i can enter new product. In that same form i have listbox where i show the current product from the database.
I want to know how to update that listbox as i enter new product into the database so that user can see the current content of the product table.
my code to load the listbox
Try Dim ds As New DataSet Dim cmd As New OleDbCommand
[Code].....
To sum it up, what i want is something that will refresh the current display of the listbox so user can see the actual and updated contents of the database.
with the above code, the newly entered product/data can only be seen when the program is closed and reopened again. Which is not very convenient.
I need to populate data (Patient ID and name) from a MS Access Database table (PetientInfo) into a listbox depending on date (Datetimepicker). The listbox item will change upon date changed.
When I select a item from listbox the details of the patient will show to the textboxes.
I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String) Try TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
