Hi, I have a problem with RTF rendering.

When I render RTF file, each line of the file is placed on seperate page. I using the following code:

f = New System.IO.StreamReader("001.rtf")

Russ,

Thank you for your help, I have tried the application on XP, and it's working well. I have problem only on Win2000. Do you know the reason of this problem?

 Did anyone ever get an answer to this?  Does moving up to the latest release help?  We are having the same problem where each line prints on another page with RTF. 

Please post a sample and indicate which version of C1Preview you're using, and I will look into this. Thanks. 

 Our problem is occurring on Win2K only.  We are using version 2.6.20063.304.

 What we are doing is similar to the original post except we use RenderDirect(x, y, obj). 

DOC1.StartDoc()

Dim objRender As C1.C1Preview.RenderRichText
objRender = New C1.C1Preview.RenderRichText(DOC1)

objRender.rtf = <rich text string>

DOC1.RenderDirect(x, y, objRender)

Please provide the EXACT RTF string or file that you're using. As I said, better yet please provide a complete sample that I can actually run. Thanks. 

How's this?  I can provide a zip file of the solution if you want the whole thing but I will need an email to send it to because I cannot attach here.

I don't think there ever was a build  2.6.20063.304 - there was a  2.6.20063.334 though, so I assume you mean that.

Most probably the problem is caused by an old version of MS RTF dll(s) on that system. Try locating a newer msftedit.dll (e.g. version 5.41.15.1509 works fine) and put it in the same directory with your app's executable. Hope this helps.

 Well that worked for us.  We took the msftedit.dll off of an XP machine and put it in the project directory on the Win2k machine and it worked.   Did you have to do this on your Win2K machine or did the proper version already exist?  What Service Pack do you have installed on the Win2K machine?    I need to identify the proper SP or hotfix which includes the correct dlls.

AFAIK, the msftedit.dll is shipped with several MS products, e.g. with Office. It also ships with the newer operating systems (Vista). I do not know which Win2K SP - if any - installs it. I would suggest you contact Microsoft to get this info.

 Dima,

I appreciate your patience.  This is what I have found in my research with Microsoft.  RegEdit 4.1 (or msftedit.dll) is not supported on Windows 2000. Before msftedit.dll they had RegEdit 1 thru 3 - or RichEd20.dll.  That is what ships with Win2K.  It seems like that it would follow then that there are some unsupported features (ie. Rending Rich Text) of the C1 components on a Win 2K environment. 

I don't know how msftedit.dll got on your Win2K machine.  It might have been installing MS Office or it may have been manually copied.  However, I cannot reasonably ask my customers to install MS office on their Win2K machines in order to get this to work properly if that was in fact how it got there.   I can find no SP or hotfix that places msftedit.dll on a Win2K machine.

Thanks for the info/link. You cannot ask your customers to install MS Office, but I think you could include msftedit.dll in your app's installation - provided of course that MS licensing allows it (which I do not know). Not really sure what else to suggest - our RTF support relies on whatever is provided by the system, and I don't think we can or should change that.
