Hello, I'm currently evaluating your Words server product.  I have a legacy system where snippets of preformatted paragraphs are saved to the database in rtf format.  The existing system using ms word ole to replace placeholder tags with the preformatted rtf snippets (i.e. fonts alignment, etc). For example:

{\rtf1\ansi\ansicpg1252\deff0\deflang1033\deflangfe1033{\fonttbl{\f0\froman\fprq2\fcharset0 Times New Roman;}{\f1\fnil\fcharset2 Symbol;}}

\b\fs24CHEM-3 CHEMICAL SAFETY (I)\b0\par

The Material Safety Data Sheets of chemicals currently used in the workplace should be reviewed to ensure that proper safety measures and personal protective equipment are being used.  If not, steps should be taken to follow outlines set forth by the manufacturer of the chemicals.

}

Range.Replace throws the special characters not allow exception and placing the snippet in a datatable and merging with mergefields just shows the rtf formatting as opposed to recogizing it as rtf markup and applying the markup to the text.

With over 200 existing word templates that use this approach for dynamically creating documents, I need a way of inserting the rtf encoded text and having it honored as ms word does.  Preferably doing the Range.Replace. 

Any suggestions?

thanks, Mark

Hi

 

Thanks for your request. I think that you can use ReplaceEvaluator to achieve this. You can’t directly insert rtf string into the document. But you can insert document into another document. So you can try using the following code snippet.

 

public void Test108()

{

    //Open template document

    Document doc = new Document(@"Test108\in.doc");

    //Create regex

    Regex regex = new Regex("stringToReplace");

    //Replace placeholder with rtf using ReplaceEvaluator

    doc.Range.Replace(regex, new ReplaceEvaluator(ReplaceEvaluator108), false);

    //Save output document

    doc.Save(@"Test108\out.doc");

}

private ReplaceAction ReplaceEvaluator108(object sender, ReplaceEvaluatorArgs e)

{

    //Get MatchNode

    Paragraph parentParagraph = e.MatchNode.ParentNode as Paragraph;

    //Read RTF string from file. in your case you get this string from database   

    string rtfString = File.ReadAllText(@"Test108\test.txt");

    //Get bytes from string, this is needed to create MemoryStream

    byte[] rtfBytes = Encoding.UTF8.GetBytes(rtfString);

    //Create memorystream

    MemoryStream rtfStream = new MemoryStream(rtfBytes);

    //Create document from stream

    Document rtfDoc = new Document(rtfStream);

    //Insert rtd document into destination document

    InsertDocument(parentParagraph, rtfDoc);

    //Return Replace action (remove palaceholder)

    return ReplaceAction.Replace;

}

 

Insert document method you can find here.

I hope this could help you.

 

Best regards.
