 Posted: Thu Dec 04, 2003 5:14 am Post subject: Need help with checkboxes and java |
 |
|
I have a writer document that has fields, bookmarks and checkboxes in it.
I need to set the values for fields, insert some text at bookmarks and check/uncheck checkboxes, depending on data read from a DB.
All this is done in JAVA: I have successfully updated fields and inserted text at bookmark position, but I do not understand how to get hold on checkboxes to change the State:
have you any JAVA sample code that can access the checkbox ByName, starting from the XComponent writer document object that I have opened?
Thanks in advance, Frank |

Thank you very much, in any case. I solved the problem in another way, in the mean time, but your neat solution is very much appreciated.

Good to read that

I posted some code snippets, where I found unanswered questions in this forum. I hope that other people with the same problems that I had now will find the answer here.

As I already stated, most of the code is from the Developers Guide.
With kind regards
