I set up my Temp Lic. And switch from Kit to Facades. A PDF created with
Protected Sub btnRemovePn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRemovePn.Click
Dim contentEditor As New PdfContentEditor()
contentEditor.ReplaceTextStrategy.IsRegularExpressionUsed = True
contentEditor.ReplaceTextStrategy.ReplaceScope = ReplaceTextStrategy.Scope.REPLACE_ALL
contentEditor.ReplaceText("Page [0-9]* of [0-9]*", " ") '--runtime error generated here as "At most 4 elements (for any collection) can be viewed in evaluation mode."
'save output PDF file
But there are several issues on created PDF
1. When open the PDF, the first page is blank. After move page down and up, the first page is displayed
2. Only only the page number ("Page [0-9]* of [0-9]*") is removed, but also the timestamp that is located the next line of page number is also disapeared.
3. When send to PDF to printer, the error message of Adobe Reader says: "An error exists page. Acrobat may not display the page correctly. Please conract the person who created the PDF document to correct the problem."
he issues don't seem to be seen with Aspose.Pdf.Kit
