Conversion Help!

[Anjari]

Hello all!

Can someone please help me convert this to VB??? My C# is very weak!

        protected void btnContinueShopping2_Click(object sender, EventArgs e)
        {
            /*
            if (ViewState["ReturnURL"].ToString() == "")
            {
                Response.Redirect(AppLogic.GetCartContinueShoppingURL(SkinID, ThisCustomer.LocaleSetting));
            }
            else
            {
                Response.Redirect(ViewState["ReturnURL"].ToString());
            }
             * */

I assume you mean VB.NET? Not VB6?

And we would basically need the whole code file. Because some of the variables in there are not declared in that particular function.

I don't usually do this, but I was bored:

Protected Sub btnContinueShopping2_Click(sender As Object, e As EventArgs)
  Dim rs As IDataReader = DB.GetRS("Select pv.VariantID, pv.Sizes, pv.Colors from ProductVariant pv join product p on pv.ProductID = p.ProductID where p.TrackInventoryBySizeAndColor=1 and (sizes not like '' or colors not like '')")
  
  While rs.Read()
    Dim sizes As String = DB.RSField(rs, "sizes")
    Dim colors As String = DB.RSField(rs, "colors")
    
    If sizes.Length > 0 AndAlso colors.Length > 0 Then
      Dim colorarray As String() = colors.Split(","c)
      Dim sizearray As String() = sizes.Split(","c)
      
      Dim i As Integer = 0
      
      While i < colorarray.Length
        ' Clean Price Modifiers
        If (colorarray(i).IndexOf("["c) <> -1) Then
          colorarray(i) = colorarray(i).Substring(0, colorarray(i).IndexOf("["c) - 1)
        End If
        
        Dim x As Integer = 0
        While (x < sizearray.Length)
          ' Clean Price Modifiers
          If (sizearray(x).IndexOf("["c) <> -1) Then
            sizearray(x) = sizearray(x).Substring(0, sizearray(x).IndexOf("["c) - 1)
          End If
          
          DB.ExecuteSQL("insert Inventory(VariantID,Color,Size,Quan) values(" + DB.SQuote(DB.RSFieldInt(rs, "VariantID").ToString()) + "," + DB.SQuote(colorarray(i)) + "," + DB.SQuote(sizearray(x)) + ",100)")
          x += 1
        End While
        i += 1
      End While
    Else If sizes.Length > 0 AndAlso colors.Length = 0
      Dim sizearray As String() = sizes.Split(","c)
      
      Dim i As Integer = 0
      
      While i < sizearray.Length
        ' Clean Price Modifiers
        If (sizearray(i).IndexOf("["c) <> -1) Then
          sizearray(i) = sizearray(i).Substring(0, sizearray(i).IndexOf("["c) - 1)
        End If
        
        DB.ExecuteSQL("insert Inventory(VariantID,Size,Quan) values(" + DB.SQuote(DB.RSFieldInt(rs, "VariantID").ToString()) + "," + DB.SQuote(sizearray(i)) + ",100)")
        i += 1
      End While
    Else If (colors.Length > 0 AndAlso sizes.Length = 0)
      Dim colorarray As String() = colors.Split(","c)
      
      Dim i As Integer = 0
      
      While i < colorarray.Length
        ' Clean Price Modifiers
        If (colorarray(i).IndexOf("["c) <> -1) Then
          colorarray(i) = colorarray(i).Substring(0, colorarray(i).IndexOf("["c) - 1)
        End If
        
        DB.ExecuteSQL("insert Inventory(VariantID,Color,Quan) values(" + DB.SQuote(DB.RSFieldInt(rs, "VariantID").ToString()) + "," + DB.SQuote(colorarray(i)) + ",100)")
        i += 1
      End While
    End If
  End While
  
  rs.Close()
  rs.Dispose()
End Sub

That's an almost 1:1 conversion, save for a couple of insignificant changes (removed some redundant ToString calls on strings).

Looking at the code, you could probably condense it a lot; the logic looks like it has some redundancy. But I'll leave that to you.

Also, you might want to consider using a Using...End Using block rather than manually calling the Close and Dispose methods on your recordset object. Using blocks make the cleanup calls implicit, so as long as you open with a Using statement instead of Dim there is no chance of you forgetting to dispose of objects properly.


Look for a utility called 'InstantVB' by a member of ours, David Anton, for automated syntax conversions.
