Default Query about code

The code below is for the combo box to retrieve items from the database. But now the problem I face is in the

Friend WithEvents CatCodeComboBox As System.Windows.Forms.ComboBox.(from the code).


For the

Friend WithEvents CatCodeComboBox As System.Windows.Forms.ComboBox,

the error is 'CatCodeComboBox is already declared as 'FriendWithEvents CatCodeComboBox As System.Windows.Forms.ComboBox' in this class. I do not know why this error has popped up and how do I solve it?


Code:
Imports System.Windows.Forms.DataGrid

Imports System.Data

Imports System.Data.SqlClient

Public Class InventoryMainForm

Private CatCodeDesc As String

Private CatCode As String

Private WarehouseLocation As String

Private Warehouse As String

Private UOMCode As String

Private subcatcode As String

Private subcat1code As String

Private subcat2code As String

Private subcat3code As String

Private AddNew As Boolean

Dim DQcheck As New SqlCommand

Dim DHcheck As New SqlDataAdapter

Dim DScheck As New DataSet

Dim Dvcheck As New DataView

InitializeComboBox()

 

'Declare CatCodeComboBox as combo box

Friend WithEvents CatCodeComboBox As System.Windows.Forms.ComboBox

' This method initializes the combo box in Item Category Level 1, 

' adding data from the table inv_category but limiting the drop-down size 

' to six rows so the combo box doesn't cover other controls when it expands.

Private Sub InitializeComboBox()

Me.CatCodeComboBox = New System.Windows.Forms.ComboBox

Dim connString As String = "server = 192.168.1.23;" + "integrated security = SSPI;" + "database = LBB"

Dim conn As New SqlConnection(connString)

Dim strSQL As String = "SELECT ict_code FROM inv_itemcategory"

Dim da As New SqlDataAdapter(strSQL, conn)

Dim ds As New DataSet

da.Fill(ds, "inv_itemcategory")

With CatCodeComboBox

.DataSource = ds.Tables("inv_itemcategory")

.DisplayMember = "ict_code"

.ValueMember = "ict_code"

.SelectedIndex = 0

End With

Me.CatCodeComboBox.Location = New System.Drawing.Point(95, 32)

Me.CatCodeComboBox.MaxDropDownItems = 5

Me.CatCodeComboBox.DropDownStyle = ComboBoxStyle.DropDown

Me.CatCodeComboBox.Name = "CatCodeComboBox"

Me.CatCodeComboBox.Size = New System.Drawing.Size(292, 21)

Me.CatCodeComboBox.TabIndex = 0

Me.Controls.Add(Me.CatCodeComboBox)

End Sub

Default

Search for all occurences of "Friend WithEvents CatCodeComboBox" You can only have one instance of that statement. Check every box that will cause the search to include more areas: whole project, include hidden text, etc.

This statement should be generated by the form designer. If you are adding this statement through other means, you are going to run into troubles (even if you didn't set out to do that).
