In some cases a loop may occure if the following code is used to create a PDF file. The exact reason for this endless loop is unknown.

Quote:
While True
thedoc.FrameRect()

If thedoc.GetInfo(TheId, "Truncated") <> "1" Then
Exit While
End If

thedoc.Page = thedoc.AddPage()
TheId = thedoc.AddImageToChain(TheId)
End While


The following code solves this problem.

Quote:
Dim theID As Integer = 0
Dim theText As String = "This PDF file is generated by WebSupergoo ABCpdf.NET on the fly"

Dim theDoc As Doc = New Doc()
theDoc.Width = 4
theDoc.FontSize = 32
theDoc.Rect.Inset(20, 20)


theDoc.FrameRect()
theID = theDoc.AddHTML(theText)
While theDoc.GetInfo(theID, "Truncated") = "1"
theDoc.Page = theDoc.AddPage()
theDoc.FrameRect()
theID = theDoc.AddHTML("", theID)
End While

theDoc.Save(Server.MapPath("textflow.pdf"))
theDoc.Clear()
response.write ("PDF file written<br>")
response.write ("<a href=""textflow.pdf"">View PDF File</a>")

With this solution, sometimes you end up with empty pages
Iy you use in this case also "AddImageToChain" it might works better
Code:

    While brutpdf.GetInfo(brutID, "Truncated") = "1"
      brutpdf.Page = brutpdf.AddPage()
      brutID = brutpdf.AddImageToChain(brutID)
    End While


edit: The TheDoc.FrameRect() In Joey's example will create a border around the rect, The websupergoo examples also use this, but It's easyer to not use it.
