View 7 RepliesI'm using VB studio express 2008. I have created a combo box which the user uses to search a client, how do i program it so that when the client is highlited in the combo box it will show in a listbox with all the details of this client wich has been added previously to the database.
in short..
User browse a client in combo box. Selects a client. Information is shown in a listbox. example. telephone number, address, ect.
I ran into a problem where the listbox is taking awfully long time to show up. This is not the same in java(It took very very less time - one second max). So, is there any remedy to this??, any other form control??, or some other way?? imports System.Threading imports System.Windows.Forms
[Code]...
When I place data into the list box, I would like the new information to be visible at the bottom of the list without having to have the user use the scroll bar to see it. The data should scroll up automatically as new data is placed into the listbox. Can this be done?

View 2 RepliesAlright it's been awhile since I messed with this project, so here goes. It's an appointment scheduler and everything works except two things: I can't edit existing appointments and it only records the current time, not the timeslot I click on.
If I try to edit an existing appointment it doesn't get the row data, just shows me blank text boxes. I assume I have to have those text boxes read the info from the database, but I don't know how to do that.
This is how it looks:
So, you double click a time slot and it looks like the second window. You can right click on an existing appointment to edit it, but when you do that all the text boxes remain blank like you're inserting a new one.
What code would I use to read whatever row's data I am trying to edit and insert it back into the boxes?
Here is the code I use to add new rows to the DB:
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim NR As TestAppointmentDataBaseDataSet.AppointmentRow

I don't understand what's going on here I published my project, and when I create new records and save them, everything gets saved and shows up each time I run the program.I open the database in SQL Server and none of the tables have the new data, but it still shows up when I run the program each time.

I'm having a problem with my software.
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:

View 2 RepliesI 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.
