I am new to vb.net i need to know how to display a database data on listbox
View 1 RepliesI'm creating a project for my brother's thesis for his VB subject.Now, the thing is, I'm trying to display row data from database to the (already binded) textboxes in form1. As you may know, this procedure requires that the program:
1. Declares an sqldatareader, sqlcommand, and an sqlconnection.
2. open the sqlconnection.
3. ....and use the sqldatareader to fetch the data from the source file.
The database file is made using sql server compact 3.5 and is located on same pc as where I'm making the program.The problem is, I'm getting stumped in trying to connect to the sql server. I'm getting a 26 error "error locating server/instance specified". installing sql server 2008 management studio to allow remote connections (which was already allowed in the 1st place), enabling TCP/named pipes protocol in the config manager, and enabling sql server browser service. I dont have spi firewall on since my isp has its own firewall on and xp fwall is off too. What I'm not sure about is my connection string as it might have been impeding me to connnect to server. How do I form out the correct connect string?

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

View 2 RepliesIs it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]

I am working with a future value application and I am trying to display the calculated future values in a listbox. For instance, I input the monthly investment, the yearly interest rate and the number of years into textboxes and I want the application to list out the future value for each year until the number of years in which I entered is reached. I cannot figure out how to get the code to display the value after each year. I am trying to use the "mod" operator to display the value each time the 12th month comes around.[code]...
View 7 RepliesI'm trying to create a for loop that will display the values (favorite programming languages) a user selects for a listbox.
So far I have this:
Dim selectedLanguages As String = ""
For intLoopIndex As Integer = 0 To languageListBox.Items.Count - 1
[code]....
So far, no matter how many items they select it will display a comma even if only one item is selected, example "C#,"However this is what I need it to do:
1. If the user selects one programming language than it should just printout the selected course with a period right after it. Example: C#.
2. If the user selects two languages it needs to have the text "and" between them followed by a period. Example: VisualBasic.Net and C#.
3. If the user selects three or more languages it needs to seperate them like this for example (again with a period at the end): VisualBasic.Net, C#, and Asp.net.
Before I begin, want to say this is my first post and I am a newbie. My first time using VB. How can I add values in a listbox that were entered by a user to another textbox in total?For ExampleSay my code for now is this.
ListBox1.Items.Add(textBoxValue.Text)
Dim X As Double
X = textBoxValue.Text

View 4 RepliesI have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically.

I've been ttrying to code an app that will act like the VB intellisense, without the added properties. In short, when I type (in a multiline RichTextBox), the letter t I would like the populated listbox show at that point (because "Then" is a word in the listbox) and if I click "Then" in the listbox have it "autocomplete" the word and display it in the color blue.
lstKeyWords.Location = rtb1.GetPositionFromCharIndex(rtb1.Selectionstart + 10)
lstKeyWords is the ListBox and rtb1 is the RichTextBox - This was the only way I could get the ListBox to show in the "almost" correct position?
I know this is a very simple question. But somehow I cannot solve this problem. I have a listbox and a textbox. I want to display the text in the Listbox when typed in a textbox.
View 1 RepliesIve got a Listbox which displays a data/record from a SQL database, it displays "Amount" and only numbers would appear. it has a datasource.
Goal: I'd Like to get the total sum of those numbers from the Listbox and Display it to a textbox automatically or by button click event.
I thought of two ways to do this, but I don't have a clue on what to do.
1. I tried summing it all up on that exact Listbox and display the total on the textbox, here's the code that i came up with..
[CODE]...........
But the data im working with is from a database, so i got this error:Conversion from type 'DataRowView' to type 'Double' is not valid.
2. I thought of having another Listbox and "Copy" the contents shown on the Listbox1 and then sum it all up on the Listbox2, then lastly display the Total on the Textbox. I did a little research on how to accomplish that but all the clue i found is that i have to disconnect the listbox data from the datasource from being bound, and reconnect it again.. I really don't have any idea on how i could do that with an SQL database.
Here's a quick flow on what im trying to accomplish to make things.
Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
How could I link a Listbox to a Textbox? So each Listbox item holds string data, and when I click that Listbox item, it shows it's string data into the multiline Textbox. For example
I have a listbox item names "Numbers". It holds this data:
1
2
45
84
So I want it to when I select this item in the listbox, it display the number data into the multi line textbox.
The following is the code that i used to store all the values in the listbox ito the access database.but it is not working.I didn't get any error.but the values in the listbox is not being stored in the database.The field in sample table that stores the value from listbox is a multivalue field.[code]...
