Why does ReplaceText return false?

SyntaxEditor for Windows Forms Forum

I am trying to do a ReplaceText in a SyntaxEditor control, and sometimes it returns false. Since it does not throw an exception there is no way for me to tell why it returns false.

What are the possible reasons for a return of false on this method?

thanks,

Gil

Looking at the implementation I would say the method returns false if the text region is (partly) read-only or the operation has been cancelled.

That was it, the region was readonly! It's strange that the ReplaceText has an option (DocumentModificationOptions.CheckReadOnly) for that (which I don't use), but I'm glad it works.

 

thanks!

Hi Gil,

The false result should only happen if either the modification occurs within a read-only range (and the CheckReadOnly flag on the modification is set), or if the Document.PreTextChanging event had a handler that said to cancel the modification.
