[RESOLVED] Count Duplicate entries in TextBoxes

Hello.

I have 50 Texboxes.

I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.

Any idea on how to do this. I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.

Any help will be appreciated.

Uhhh this is the only solution that popped to my head when I looked at it. No doubt there are probably cleaner methods:

vb Code:

Dim totalrep as int32 = 0
For each tb As TextBox In Me.Controls
   Dim myText As String = tb.Text
   For each txtBox As TextBox In Me.Controls
       if txtBox.Text = myText then
         totalrep += 1
       End If
   Next
Next

Only glaring problem I see is duplicate counts (i.e TextBox2.Text = TextBox1.Text and TextBox1.Text = TextBox2.text) which would result in double results. So yeah, I guess you'd have to figure out how to fix that (I'm not sure if dividing the final result by 2 would do it...just a suggestion)

may be you can try this:

Code:

Private Function GetProductSummary() As DataTable
        Dim dtSummary As DataTable
        Dim dcCol As DataColumn
        Dim txtBox As Control
        Try
            dtSummary = New DataTable("Order")
            dcCol = New DataColumn("ProductCode", Type.GetType("System.String"))
            dtSummary.Columns.Add(dcCol)

            dcCol = New DataColumn("Qty", Type.GetType("System.Int32"))
            dtSummary.Columns.Add(dcCol)

            For Each txtBox In Me.Controls
                If txtBox.GetType.Name = "TextBox" Then
                    Dim drProducts() As DataRow
                    drProducts = dtSummary.Select("ProductCode = '" & txtBox.Text.Trim & "'")
                    If drProducts.Length > 0 Then
                        drProducts(0).Item("ProductCode") = txtBox.Text.Trim
                        drProducts(0).Item("Qty") += 1
                    Else
                        Dim drProduct As DataRow = dtSummary.NewRow
                        drProduct.Item("ProductCode") = txtBox.Text.Trim
                        drProduct.Item("Qty") = 1
                        dtSummary.Rows.Add(drProduct)
                    End If
                End If
            Next

            Return dtSummary
        Catch ex As Exception
            Throw ex
        End Try
    End Function

Thank you guys!!!!

Doing it via a datatable never crossed my mind.
