.NET Forum / Windows Forms / WinForm Controls / February 2007RichTextBox.Rtf - doesn't show if images in the rtf - Vista only
Hi; We have a C# program (a Word AddIn) that works fine on Windows XP. But when running on Vista (and Word 2007) if we call RichTextBox.Rtf = "...rtf file..."; and the rtf file has a bitmap in it - then the control shows nothing. It's not that the bitmap is missing and the rest is there - nothing is there. Is this a known bug in .NET on Vista?  Signaturethanks - dave david_at_windward_dot_net http://www.windwardreports.com Cubicle Wars - http://www.windwardreports.com/film.htm Hi Dave, The Rtf string of a rtf file which has bitmaps in it constains some binary information. I don't know how you get the Rtf string of the rtf file, but it seems that the Rtf string you are using may not correct. Since you're going to show the content of a rtf file in a RichTextBox control, why not use the LoadFile method of the RichTextBox to do it? I have performed a test on the LoadFile method and confirms it works. I suggest that you use the LoadFile method of the RichTextBox to see if the problem still exists. Hope this helps. If you have any question, please feel free to let me know.

Hi; I can't use the LoadFile because the rtf does not exist on disk. Our code works fine on WindowsXP/Word 2003 (and earlier versions). It's just Vista/Word 2007 that is a problem. And only if there is a bitmap. The bitmap is uuencoded so the entire string is ascii - there is no binary characters.

Hi Dave, Thanks for your feedback. Since Linda is on vacation this week, I will continue to work with you. Is it possible for you to create a little sample project with detailed steps to help me reproduce this problem? This would be helpful to improve our understanding to your problem. Thanks.

This is one of those "wonderful" bugs. When we use our Word AddIn (AutoTag) to display a rtf file in a form, it works for all cases on WinXP/Word 2000/2002/2003. But on Vista/Word 2007 it does not work for complex rtf files. So I wrote a little test app that just has a richTextBox to display the same rtf file. And on Vista - it works. It's the exact same rtf file. So I don't think I can give you a sample. Our AutoTag program is way too big to use. Someone else will find this bug with a simple sample soon and report it. Can I ask that if you see something about this problem - and a work around, that you post a reply here then?

Hi Dave, Yes, I understand your concern. However, this is mainly a Word Addin issue, my specialist mainly focuses on .Net Winform, so I do not have much experience to share when the problem is not reproduced out. In this scenario, I recommend you post this question in microsoft.public.office.developer.automation for better help. There will be more experience people there. Thanks for your understanding.
