Re: [api-dev] How to identify and remove empty pages in writer document.
Hi Paolo, I would if I could :-) Unfortunately the adding / removing of text to/from the template document (which in itself contains a lot of formatted text) is database driven and dependent upon a whole host of factors based around a particular customers geographic location. Obviously the template has to cater for all possibilities and as large amounts of text get added / removed the original page boundaries fluctuate.

Re: [api-dev] How to identify and remove empty pages in writer document.
Hi Malcolm, maybe the macro I just wrote will help you. Please note that it is by no means 'perfect' because I have not tested all possible situations. The problem is that there is no such API function as to recognize whether a page is empty, so you have to check it on your own. Because there are many ways to skip a page it is also not doable in one specific and simple way. My macro checks the first 'chars' characters on the page, if they are all whitespace or if there is none but a page break it will remove the page. You can set the value to whatever you want (I check for the first 50 characters), depending on how well your document is structured. For example if you don't have messy formatting (messy means i.e. if some pages only have text in the middle and don't start at the top) then you can set it be low, otherwise set this value much higher. code Private chars as Integer 'specifies the number of characters checked at the beginning of every page Function emptypage Dim i as Integer chars = 50 odoc = thisComponent 'if you have problems with thisComponent for the new OOo 2.0 builds, 'use Stardesktop.getCurrentComponent() instead otext = odoc.getText() cur = otext.createTextCursor() cur.goToStart(False) view = odoc.getCurrentController() viewcursor = view.getViewCursor() 'retrieve total page number viewcursor.jumpToLastPage() npages = viewcursor.getPage() viewcursor.jumpToFirstPage() For i = 1 to npages cur.goRight(chars, True) txt = Trim(cur.String) If len(txt) = 0 Then DeletePage(cur, i) Else If Asc(txt) = 32 Then DeletePage(cur, i) Else viewcursor.jumpToNextPage() cur.goToRange(viewcursor.getStart(), False) End If End If Next i End Function Function DeletePage(cur, i as Integer) cur.goLeft(chars, False) cur.goToNextWord(True) cur.setString() i =+ 1 End Function/code Hope this helps you. 2005/5/14, malcolm cooke [EMAIL PROTECTED]: Hi Paolo,I would if I could :-)Unfortunately the adding / removing of text to/from the template document(which in itself contains a lot of formatted text) is database driven anddependent upon a whole host of factors based around a particular customers geographic location.

U, this works better I guess: REM * BASIC * Private chars as Integer 'specifies the number of characters checked at the beginning of every page Function Delete_empty_pages Dim i as Integer chars = 50 odoc = thisComponent 'if you have problems with thisComponent for the new OOo 2.0 builds, 'use Stardesktop.getCurrentComponent() instead otext = odoc.getText() cur = otext.createTextCursor() cur.goToStart(False) view = odoc.getCurrentController() viewcursor = view.getViewCursor() 'retrieve total page number viewcursor.jumpToLastPage() npages = viewcursor.getPage() viewcursor.jumpToFirstPage() For i = 1 to npages cur.goRight(chars, True) txt = Trim(cur.String) If len(txt) = 0 Then DeletePage(cur, i) Else If Asc(txt) = 32 Then DeletePage(cur, i) End If End If viewcursor.jumpToNextPage() cur.goToRange(viewcursor.getStart(), False) Next i End Function Function DeletePage(cur, i as Integer) cur.goLeft(chars, False) cur.goToNextWord(True) cur.setString() i =+ 1 End Function2005/5/14, Christian Junker [EMAIL PROTECTED]: Hi Malcolm, maybe the macro I just wrote will help you.

[api-dev] Accessing metadata.
I have a need to strip all metadata on a document programmatically that's not required for operation. I currently use the DocumentInfo interface and can access the properties and set everything that isn't required to anemptty sring however I have a couple of small problems. I check to see if attributes are removable and if so I'd like to take them out however I haven't figured out how to actually delete them, can someone provide some help on how it can be done given a handle to the property. I also noticed that the DocumentInfo interface doesn't include the Info1-4 tags that are present in the properties of all documents. I didn't notice this at first because I thought DocumentInfo helf it all. Is there any generic interface applicable to all documents which also contains these? Any help would be appreciated.
