FetchVersion outputStream
Matt_Miranda
Has anyone used the FetchVersion function with outputstream instead of filepath? I am having some trouble getting this to work. Any help is appreciated.

Message from Carsten Kulms via eLinkAttached you find a simple example (Java) that works.It simply fetches a document's content to stdout.No production quality, just a hint.Provided "as is" without warranty of any kind, either expressedor implied, including, but not limited to, the implied warranties ofmerchantability and fitness for a particular purpose. The entire riskasto the quality and performance of the program is with you. Should theprogram prove defective, you assume the cost of all necessary servicing,repair or correction.P.S.: If you see something likeException in thread "main" com.opentext.api.LLUnknownFieldException:LLValue unknown field name: FileAttributesthen an error occured at LES side (possibly wrong call parameters) whichresulted in an incomplete response to the LAPI client.

This is the way we do it:Dim oMemStream As New System.IO.MemoryStreamDim returnValue As Byte()Dim StartTime = DateTime.NowDim iStatus As Integer = MyBase.DocumentsAPI.FetchVersion(MyBase.VolumeID, MyBase.NodeID, Me.m_iVersion, New System.IO.BinaryWriter(oMemStream))MyBase.CheckError(iStatus)returnValue = oMemStream.GetBuffer()If your document was a texte document, you could then doDim strValue as String = (New System.Text.ASCIIEncoding).GetString(returnValue)If you want to write to the ASP.NET output streamOutputStream.Write(returnValue, 0, returnValue.Length)OutputStream.Close()
