question about foreach - ComponentPro Scam Archive

Subject: question about foreach Date: 2011-07-15 22:02:19 From: ntek designs Source: question-foreach ----------------------------------------------------------------------

im trying to change my application over to use a template engine.

before i was using a stringbuilder and building the html. i have two tables in each of my templates that will require being created on the fly using a for each loop.

the tables are for displaying images and vehicle options.. on the first template the images table has two columns, and x amount of rows... i did this by doing a for each loop, stepping by 2, creating a row for each iteration and creating the columns according..

the following code demonstrates what i was doing..

            If ad.HasImages Then
                With ad
                    Select Case templateID
                        Case Is = "1"
                            sb.Append("<br><br><table border='0' cellpadding='10' cellspacing='0'>")

For imagecounter As Integer = 1 To .ImageURLs.Count Step 2 'images are dislayed side by side so we step by 2
sb.Append("<tr>") 'table row start tag

                                'add column and image
                                sb.Append(String.Format("<td><img width='400' border='0' src='{0}'></td>", _
                                              .ImageURLs(imagecounter - 1))) 'append image (subtracted 1 because string array is zero based)

                                'check if there is at least one more image in the array, if so, add the column and image
                                If imagecounter < .ImageURLs.Count Then
                                    sb.Append(String.Format("<td><img width='400' border='0' src='{0}'></td>", _
                                                .ImageURLs(imagecounter))) 'append the following image
                                End If

sb.Append("</tr>") 'table row end tag
Next

                            sb.Append("</table><br><br>")
                    End Select
                End With
            End If

i need to reproduce this action and perhaps even more complex ones using this template engine. is it possible?

any examples or input would be greatly appreciated.

thanks.
