Create your HTML report and save the result in a Notes document. This tip works both in Notes and Web. In Notes, use UIView event queryOpenDocument with an workspace.OpenUrl method.
Code
In the Notes form, write the code to retrieve data, and write the html-code in a text variable, like this:
'Variable for save html
dim html as string
html=html+"<table width=100% border=0 cellspacing=1 cellpadding=3>"
'LOOP
do while not doc is nothing
html=html+"<tr style='font- family:Verdana; font-size=10pt;color:midnightblue;background-color:whitesmoke'>"
html=html+"<td>"+doc.myTitle(0)
html=html+"<td>"+doc.myValue(0)
...
html=html+"</tr>
html=html+"</table>"
loop
' at the end, save the text variable in
' a rich text item named HTML
' note that the field MUST be named HTML!)
Dim rtitem As NotesRichTextItem
Set rtitem = New NotesRichTextItem(doc, "HTML" )
Call rtitem.AppendText( html )
Call doc.save(True,False)
Now, reopen the document and the report appears!
