Good evening Forum,

 

I'm looking for a way to extract several files contained in a binded rich text field onto the file system (on a network share)

 

I don't want user interaction, just click a button to extract / create the files, no popup to allow download....

 

I think I can do something with the next piece of code: 

 

var inPath:string = requestScope.filepath;

var n:int = inPath.lastIndexOf(".");

var outPath:string = inPath.left(n) + "Copy" + inPath.right(inPath.length - n);

var inStream:NotesStream = session.createStream();

if (inStream.open(inPath, "binary")) {

if (inStream.getBytes() > 0) {

var outStream:NotesStream = session.createStream();

if (outStream.open(outPath, "binary")) {

if (!outStream.isReadOnly()) {

do {

var buffer = inStream.read(32767);

outStream.write(buffer);

} while (!inStream.isEOS());

} else requestScope.status = "Output file exists and is read-only";

outStream.close();

} else requestScope.status = "Output file open failed";

} else requestScope.status = "Input file has no content";

inStream.close();

} else requestScope.status = "Input file open failed";

 

 

I already use something similar with HTML text contained in an edit box that I create a file from. Also using outStream.writeText.

 

So I don't think it's possible to extract the files without having to user accept the download, but It should be possible to convert to files to binary and write them like I already do for the HTML content. 

 

I hope someone will be able to help me with this? 

 

Thanks in advance, 

 

Chris

Hi Forum, 

 

In the meantime I continued testing and next code bring me close to what I need, except that the created file doesn't have the right content... Probably problem with the buffer.

 

var strId:String = "2F509C8CD8D5F9A6C125789D0066DD06";

var strFile:String = "image.gif";

//retrieve target document from current database

doc = database.getDocumentByUNID(strId);

var eo:NotesEmbeddedObject = doc.getAttachment( strFile );

strFile = eo.getName();

var outPath:string = "\\\\Server\\XXX\\XXX\\"; //Path for output

var cdir = new java.io.File(outPath);

if (cdir.exists()) {

var outFileName:String = strFile;

var fos = new java.io.FileOutputStream(outPath + outFileName);

var osw = new java.io.OutputStreamWriter(fos);

var outputStream:NotesStream = session.createStream();

var buffer = new byte[4 * 1024]; // 4K buffer

var bytesRead;

var bufferedIS = new java.io.BufferedInputStream( eo.getInputStream());

while ((bytesRead = bufferedIS.read(buffer)) != -1) {

//outputStream.write(buffer, 0, bytesRead); //Error

outputStream.write(buffer);

}

outputStream.getContents(osw);

osw.close();

bufferedIS.close();

eo.recycle();

outputStream.close();

} 

 

 

Thx in advance for the assistance.
