Convert a TXT document to PDF

When I try to convert a TXT document into a PDF using Aspose.Words, I get this error,“Unknown file format”. Why is that? I thought ASpose.Words for .NET can be used for conversion of TXT documents to PDF.

Hello

Thanks for your interest in Aspose.Words. Please see the following link to learn how to load plain text into an Aspose.Words.Document object:

Hope this helps.

Thank you very much for the reponse.
But the problem I’m facing now, is the PDF Document, gets opened, but there is no content in this. I make use of Aspose.Words for .Net and I read from a stream. This is my code.

Dim oFileStream As System.IO.MemoryStream
oFileStream = New System.IO.MemoryStream()
oFileStream.Write(File_blob, 0, File_blob.Length)
Dim builder As DocumentBuilder = New DocumentBuilder()
Using reader As System.IO.StreamReader = New System.IO.StreamReader(oFileStream, Encoding.UTF8)

    ' Read plain text "lines" and convert them into paragraphs in the document.
    While reader.Peek <> -1
        Dim line As String = reader.ReadLine()

        If line IsNot Nothing Then
            builder.Writeln(line)

        End If
    End While
End Using
Dim dstStream As System.IO.MemoryStream = New System.IO.MemoryStream()
builder.Document.Save(dstStream, SaveFormat.Pdf)

Here, when I step down the code, when it hits While reader.Peek , then it breaks comes out of the While loop. Not sure why.

Hi

Thanks for your request. You should just reset position of stream, please see the code bellow:

Dim oFileStream As System.IO.MemoryStream oFileStream = New System.IO.MemoryStream()
oFileStream.Write(File_blob, 0, File_blob.Length)
oFileStream.Position = 0

Best regards,
