VB.NET Using Combobox to retrieve data from MS SQL DataBase and fill a textbox with the data

I am working on a VB.Net project in Visual Studio 2013 project. I want a combobox to retrieve data from ms access database and fill a textbox

I have a MS Access DB Named DataDB and i have a Form Named Form1 with a Combobox on it is Named cboData and three textBox Named txtName, txtPhone and txtAddress. The DataDB holds my customer Name, Phone and Address.

I want to use the ComboBox to access the DataDB and use the value to populate three textBox Named txtName, txtPhone and txtAddress in the form(load event)

Answer 1

It is really unclear what your motive is.But as far as i think,u want to populate a combo box from an access database(maybe).Then you can try this

'create a connection string named con

Public sub MyForm_Load

Dim cmd as new OleDbCommand("Select * from [table name here-avoid brackets 
 if required]",con)

Dim adapter as new OleDbDataadapter(cmd)

Dim table as new datatable

adapter.fill(table)

ComboBox1.DataSource = table
ComboBox1.DisplayMember = table.Columns(3).ToString 'you can use column name or even row

Now, to add text to the textbox from the combo box, try :

Public Sub ComboBox1_IndexChanged

Textbox1.tex=Combobox1.text

If you think this is not what you want, then please clarify your needs

Datatable to textbox

 For i = 0 To table.Rows.Count - 1
        textbox1.Text = table.Rows(i)(3).value.ToString
    Next
