1. Register DLL in your system, run:
regsvr32 RTF2HTML.dll

2 . Add a reference to the “SautinSoft Rtf-to-Html DLL” control:

3. This is sample function:

Private Function TestRTF2HTML() As String
Dim strRet As String
Dim h As New RTF2HTML.Converter
h.OutputFormat = RTF2HTML.Html
h.Encoding = RTF2HTML.Windows_1252
strRet = h.ConvertFile("D:\test.rtf", "D:\HTML files\")
MsgBox strRet
End Function

1. Register DLL in your system, launch: Regsvr32 Rtf2Html.dll

Sample1:

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>

<%
Private Function TestRTF2HTML() As String
Dim strRet As String
Dim ImageFolder As String
Dim ImageSubFolder As String
Dim h As New RTF2HTML.Converter

h.Encoding = RTF2HTML.eEncoding.ISO_8859_1
h.PreserveImages = True
h.OutputFormat = RTF2HTML.html
h.FontFace = "Arial"
h.PreserveFontFace = True
h.PreserveFontColor = True

ImageFolder = "D:\"
ImageSubFolder = ""
strRet = h.ConvertString("This test string", ImageFolder, ImageSubFolder)
MsgBox strRet
End Function
%>

Sample2:

This is example of function on VBScript:

<% set fs = server.CreateObject("scripting.filesystemobject") set h = server.CreateObject("RTF2HTML.Converter") h.OutputFormat = RTF2HTML.Html_with_CSS h.PreserveFontColor = True h.PreserveFontSize = True h.PreserveImages = True strOut = h.ConvertString(strOut, "", "") set h = nothing strhtmlname = "Html_" & session.SessionID & ".html"'gets unique name strPhysicalFileName = server.MapPath("../temp") &"\" & strhtmlname strURL = "../temp/" & strhtmlname
if not fs.FileExists(strPhysicalFileName) then
fs.CreateTextFile strPhysicalFileName
end if
set myHtml = fs.OpenTextFile(strPhysicalFileName,2)
myHtml.write strout
myHtml.close
set fs=nothing
response.redirect strURL
%>

2). Register DLL in your system, launch:

Sample 1 - ASP.Net/VB

1. Install HTML2RTF on the webserver.
2. Use regsvr32 to register the DLL, launch: Regsvr32 Rtf2Html.dll
3. Request the aspx page in a browser from a client

rtf2html.aspx
