How does one create a dynamic Table or Grid using DHTML (VB)
Hi
I have created a simple DHMTL Project within VB6. The DHTML Pages communicate with SQL Stored Procedures.
I know how to get the DHMTL Pages to communicate with my database, but I don’t know how to create a dynamic table or grid.
I would like the following:
- I want to create a function (within VB's DHTML) which creates a table or grid dynamically on my page.
- The table or grid will be generated from any stored procedure or record set I choose.
- I will require the capability of sorting on the columns (when clicking a column header)
- I also want to be able to read a value (from one of the columns) in the selected row (selected by user).
If anyone could provide some examples of how to do the following I would be extremely greatful. You could also recieve 500 points as a token of my appreciation.
Thanks

This workaround example is the best I can find: http://www.kryogenix.org/code/browser/sorttable/

You'll need something like this:
Private Sub DHTMLPage_Load()
Dim cnn As New ADODB.connection
Dim cmd As New ADODB.Command
Dim rs As ADODB.Recordset
Dim strHTML As String
Dim j As Integer
Dim strRS As String
cnn.open "Provider=Microsoft.Jet.OL
"Data Source=C:\Program Files\Microsoft Office\Office\Samples\nort
"User Id=admin;" & _
"Password="
cmd.ActiveConnection = cnn
cmd.CommandText = "SELECT * FROM Customers"
Set rs = cmd.Execute
strHTML = "<table id='test' class='sortable'>"
If Not rs.EOF And Not rs.BOF Then
rs.MoveFirst
strHTML = strHTML & "<tr>"
For j = 0 To rs.Fields.Count - 1
strRS = CStr(rs(j).Name)
strHTML = strHTML & "<th>" & strRS & "</th>"
Next
strHTML = strHTML & "</tr>"
While Not rs.EOF And Not rs.BOF
strHTML = strHTML & "<tr>"
For j = 0 To rs.Fields.Count - 1
If IsNull(rs(j)) Then
strRS = "<NULL>"
Else
strRS = CStr(rs(j))
End If
strHTML = strHTML & "<td>" & strRS & "</td>"
Next
strHTML = strHTML & "</tr>"
rs.MoveNext
Wend
End If
strHTML = strHTML & "</table>"
DHTMLPage.Document.body.in
End Sub
Still trying to figure out the sortable columns though. You may have to transcript the Javascript to VB?

"innerText and innerHTML properties of the table and tr objects are read-only."
Unfortunately it's not possible to replace the innerHTML of tables so you'll have to regenerate the table by adding and removing rows - or replacing the entire table. The link above should help you and clarify this.
