ExecuteNonQuery is for executing commands like INSERT, UPDATE, or DELETE, which don't return any data.

To execute a SELECT query and read the results, use the ExecuteReader method[^] instead.

VB.NET

Private Sub search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles search.Click
    Using command As New OleDbCommand("SELECT * FROM datagambar WHERE NoFaktur = @nofaktur", con)
        command.Parameters.Add("@nofaktur", OleDbType.VarChar).Value = nofaktur.Text
        
        Try
            con.Open()
            
            Using reader As OleDbDataReader = command.ExecuteReader()
                If reader.Read() Then
                    Dim imagePath As String = reader.Field(Of String)("Your image path column name")
                    If String.IsNullOrEmpty(imagePath) Then
                        PictureBox1.Visible = False
                    Else
                        PictureBox1.Visible = True
                        PictureBox1.Image = Image.FromFile(imagePath)
                    End If
                    
                    ... Load other columns into the UI here ...
                    
                Else
                    ... No match: tell the user, and clear the UI here ...
                End If
            End Using
            
        Catch ex As System.Data.Common.DbException
            MsgBox(ex.Message)
        
        Finally
            con.Close()
        End Try
    End Using
End Sub
