Sql - Get Data To Textbox From The Database?
Apr 26, 2011
I have a form with one combo box and text box, and an SQL database named balance with two columns; one as customername and the other as obbalance. I had bound all of the customer name to the combo box, now what I have to do is, when a user selects a customer name from the combo box, the text box should show the obbalance of the selected customername; here, the customer name will not be repeated - only one name per customer.
Dim conectionstring As String
conectionstring = "Data Source=.SQLEXPRESS;AttachDbFilename=C:Documents and SettingsAdministratorMy DocumentsVisual Studio 2005ProjectsSHOPPROJECTSHOPPROJECTshop.mdf;Integrated Security=True;User
[Code]....
I've tried this, but I can't see the value in the text box, and obbalance is a floating-point value from the SQL database.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I'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 try to use VB .net to develop a small program. In this program, there has a form. In this form, there have several text box and toolbar. The problem is after I input text into textbox and I do not press <enter> key, I go to click save button in form's toolbar. I found that this textbox's data cannot save into database. If I press <enter> key after I input text into textbox, data can save into database properly.

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 am currently puting together a data driven application just for fun and to get to know sql. The problem i am having is on my new customer form I cannot get the data in my text boxes to save into my database table at runtime. I simply have 4 textboxes and a save button the code for my save button is as follows:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim Connection As SqlConnection = MSDB.GetConnection
Dim mySqlCommand As SqlCommand = New SqlCommand
Connection.Open()
[Code] ....
All this does is bring up an error in runtime. How to get that to work when I press save the details in my text boxes are actually saved into my database table.

I've the data in Datagridview (2 column - wavelength, absorbance) and i need to display in text box based on some reference. let say my first reference (soot it has wavelength value plus minus 2000 (range 1998 until 2002), 2nd ref NO2 plus minus 1630 (range 1628 until 1632) and others ref.
Firstly the system will find the specified wavelength in column1 (datagridview). if wavelength(column1) found in that range it will display the value in the textbox (column2- absorbance). then the information in the textbox, need to be save in oracle.

I've created a basic search form. I have a textbox with a search button and an Access Database as the backend. I have also added it as a new datasource. What I'm looking to do is grab the search string from one textbox and return the data to another textboxt. I have a table called "VehicleInfo" and I want to search the field in my table called "VehicleID" and return the vehicleID I searched for into another textbox. I'm really new to VB. I understand databases and basic code structure, I just don't have a good grasp yet on how these two work together.
