Re: [api-dev] LoadComponentFromURL using an XInputStream in Basic
snip snip snip :-) It can be solved ... if you implement an UNO Service which accepts a Sequence sal_Int8 as IN parameter and returns an XSeekable/XInputStream as result. Such service can be used in Java, C++, Basic, Phyton etcpp. Currently I do not know if such help service still exists .-) OK, for now, I will consider this as NOT possible unless I implement the service to do this myself. b) Use another filter or dont specify any filter so loadComponentFromURL() can search for it's own one. I have tried specifying, and not specifying, the filter. Then it does not depend on your content. It seams realy a problem of your non-seekable stream. But I don not understand then why the office locked up. Normaly the call loadComponentFromURL() should return without loading this content. May be you can provide some stacks (produced with an attached debugger), which shows us, where the office is hanging ? That I can try to do... I use Linux (FC4). If you have any advise on which debugger to attempt to use, that would perhaps be useful. I will see if I can figure out how to do this with gdb. It looks like I can attach it to a running process! Wahooo! I did not know that I could do that!

[api-dev] LoadComponentFromURL using an XInputStream in Basic
I am using OOo 2.0.3 on Linux FC4. I store a binary file into a database - Base document if it matters. First I tried to use a stream: oStatement.setBinaryStream(2, oStream, oStream.getLength()) The error message said that there was an error from the ODBC driver stating that the stream was NULL. I found that the following works: lLen = oStream.getLength() ReDim oData(0 To lLen-1) oStream.readBytes(oData(), lLen) oStatement.setBytes(2, oData(), lLen) I can extract the data from my database to a file. oSimpleFileAccess.writeFile(sURL, oStream) Rather than writing the file to disk, I would prefer to load the file directly. Dim oProp(0) As New com.sun.star.beans.PropertyValue oProp(0).Name = InputStream : oProp(0).Value = oStream REM oProp(1).Name = ReadOnly: oProp(1).Value = True REM oProp(2).Name = FilterName : oProp(2).Value = writer8 StarDesktop.LoadComponentFromUrl(private:stream, _blank, 0, oProp()) When I try this, however, soffice locks up and I have to manually kill soffice. The closest that I could find to a solution is in Java, but it uses a com.sun.star.lib.uno.adapter.ByteArrayToXInputStreamAdapter The speculation is that the XInputStream does not support XSeekable. http://joott.cvs.sourceforge.net/joott/jooconverter2/src/net/sf/jooreports/openoffice/converter/OpenOfficeDocumentConverter.java?view=markup -- Andrew Pitonyak My Macro Document: http://www.pitonyak.org/AndrewMacro.odt My Book: http://www.hentzenwerke.com/catalog/oome.htm Info: http://www.pitonyak.org/oo.php See Also: http://documentation.openoffice.org/HOW_TO/index.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
