I'm trying to make an army list builder for a miniatures strategy game.
I'd like to know the correct method to read a SQL table cell value and to put it for each unit into a ComboBox.text field, but only into the field.
The ComBoBox collection items should not be modified (I need them to remain as it is). I just want the ComboBox.text value to be modified with the red framed value, and for each unit
For the record, currently, I read the others table informations and load them into the others ComboBoxes this way :
Private Sub TextBoxQuantitéUnités_Click(sender As Object, e As EventArgs) Handles TextBoxQuantitéUnités.Click
Dim connection As New SqlConnection("Data Source=Server;Initial Catalog=OST;Integrated Security=True")
Dim dt As New DataTable
Dim sqlquery As String
connection.Open()
sqlquery = "select * from liste1 Order By index_unité"
Dim SQL As New SqlDataAdapter(sqlquery, connection)
SQL.Fill(dt)
Dim cmd As New SqlCommand(sqlquery, connection)
Dim reader As SqlDataReader = cmd.ExecuteReader
ComboBoxNomUnités.DataSource = dt
ComboBoxNomUnités.DisplayMember = "nom_unité"
ComboBoxTypeUnités.DataSource = dt
ComboBoxTypeUnités.DisplayMember = "type_unité"
ComboBoxAbréviationUnités.DataSource = dt
ComboBoxAbréviationUnités.DisplayMember = "abréviation_unité"
ComboBoxCoutTotal.DataSource = dt
ComboBoxCoutTotal.DisplayMember = "cout_unité"
connection.Close()
End Sub
Many thanks :-)
The ComboBox.text where I want to load the cell value
The table picture with the framed value I want to load into the cell
The original ComboBox collection I want to keep
EDIT 2 :
My table structure
Your function call
A short clip of the program in order to understand my problem
As you can see, the function seems good and when I check the ComboBoxQuality text during the execution, it seems good but for some reason, it don't change...
The others Comboboxes are sync as you can see on the upper code.
Thanks in advance...

I am currently working in windows form applications using vb.net 2013. I have two forms, we can call them form1 and form 2 for now. Form1 has a datagridview with a checkbox column that the end user will click to open form2 as a dialog form. Once form2 opens I want it to automatically load and fill two text boxes that have information from corresponding columns from the original DGV. In short, the DGV on form1 has 3 columns; JobNumber, LineNumber, and the checkbox. The end user will click the checkbox to bring up form2 and I want the Jobnumber and Linenumber to automaticaly fill into two textboxes on form2. Here is my code from form1.
'assembly dialog result form
dr = f.ShowDialog
If dr = Windows.Forms.DialogResult.OK Then
'dim y as job string
Dim Y As String = DataGridOrdered.Rows(e.RowIndex).Cells(3).Value
'open connection
Using conn1 As New SqlConnection(connstring)
conn1.Open()
Using comm1 As SqlCommand = New SqlCommand("UPDATE Production.dbo.tblFCOrdered SET Complete = 1, RackIn = 1 WHERE JobNumber = '" & Y & "'", conn1)

Form 2 code

Dim value1 As Object = FormOrdered.DataGridOrdered.Rows(FormOrdered.row_Index).Cells(3).Value
Dim value2 As Object = FormOrdered.DataGridOrdered.Rows(FormOrdered.row_Index).Cells(4).Value
TBJobNumber.Text = CType(value1, String)
TBFloor.Text = CType(value2, String)
In your form1 add:
Public Row_Index As Integer = 0 //use a simple variable
Sub datagridOrdered_CurrentCellDirtyStateChanged( _
ByVal sender As Object, ByVal e As EventArgs) _
Handles datagridOrdered.CurrentCellDirtyStateChanged
If datagridOrdered.IsCurrentCellDirty Then
datagridOrdered.CommitEdit(DataGridViewDataErrorContexts.Commit)

End Sub
Private Sub datagridOrdered_CellValueChanged(sender As System.Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles datagridOrdered.CellValueChanged

Dim checkCell As DataGridViewCheckBoxCell = _
CType(datagridOrdered.Rows(e.RowIndex).Cells(2), _ //<- here
DataGridViewCheckBoxCell)
If CType(checkCell.Value, [Boolean]) = True Then
//RowIndex = e.RowIndex you dont need this
Row_Index = e.RowIndex
BuildName.ShowDialog(Me)
End If
End If
End Sub
//Nor this
//Private _count As Integer
//Public Property RowIndex() As Integer
//Get
//Return _count
//End Get
//Set(value As Integer)
//_count = value
//End Set
//End Property
And in dialog load event use Form1.Row_Index instead:
Private Sub BuildName_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim value1 As Object = FormOrdered.datagridOrdered.Rows(Form1.Row_Index).Cells(0).Value //<- here
Dim value2 As Object = FormOrdered.datagridOrdered.Rows(Form1.Row_Index).Cells(1).Value //<- here
TBJobNumber.Text = CType(value1, String)
TBFloor.Text = CType(value2, String)
...
...
End Sub
or add a module and add the Row_Index there. You can use it then as is
Private Sub BuildName_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim value1 As Object = FormOrdered.DataGridView1.Rows(Row_Index).Cells(0).Value
Dim value2 As Object = FormOrdered.DataGridView1.Rows(Row_Index).Cells(1).Value
TBJobNumber.Text = CType(value1, String)
TBFloor.Text = CType(value2, String)
...
...
End Sub
I am connecting to database in Access that holds information on the card details. One field is a 'confiscated' tick box that signals if a card's PIN number has been entered incorrectly 3 times. I've managed to get the program to check the PIN entered is correct or not, and now I'm stuck trying to change the card's confiscated status in the database. The card number is chosen from a drop down menu. When a card is confiscated it should no longer appear in this combo box to the user. This is my code so far:

Try to add this code again to your button which made insert or update.
UPDATE
I give you another tips, that wont make your code so long and wasted memory or capacity..
Try to insert all the code to new sub, e.g :
private sub mycode
msgbox("Hello World")
end sub >> This code won't work when you debug, cause it just like a stored code, so need to be called to make it work
Private sub Form_load...... > E.g this is your form load code
call mycode >> Called the code above
end sub >> when you debug, your form will auto called the mycode
