My requirement is to save a bunch of files (more than 500) in a single zip file locally using FileReference. I am using ASZip to zip the files. Now the problem is if the number of files are more, then I am not even getting Save as dialog box.
I have tried different combinations of data to see whether it is number of files or file size limitation, but it looks like the script automatically stops (irrespective of number of files), if it can't give me the output within a minute.
This is the code that I am using
//*****test code
var myZip:ASZip = new ASZip (CompressionMethod.GZIP);
var myByteArray:ByteArray = new ByteArray();var pdfFile:PDF;
var newPage:Page;
var printPage:BorderContainer;
for (var i:int=0;i<330;i++)
{
printPage = new BorderContainer();
printPage.visible = false;
printPage.x=0;
printPage.y=0;
printPage.includeInLayout = false;
printPage.width = 816+10;
printPage.height = 1056+23;
this.addElement(printPage);
pdfFile = new PDF(Orientation.PORTRAIT, Unit.INCHES, Size.A3 );
pdfFile.setDisplayMode( Display.FULL_PAGE,Layout.SINGLE_PAGE );
newPage = new Page ( Orientation.PORTRAIT,Unit.INCHES,new Size([816+10,1056+10],"MyFavoriteSize",[8.5+10,11+10],[816/0.125,1056/0.218]));
pdfFile.addPage(newPage);
pdfFile.beginFill(new RGBColor(0xFFFFFF));
pdfFile.textStyle(new RGBColor(0x000000));
pdfFile.addImage(printPage,null,-0.5,-0.5,8.5+4,11.5+4);
myByteArray = pdfFile.save(org.alivepdf.saving.Method.LOCAL);
myZip.addFile(myByteArray,i + ".pdf");
}
Can you please let me know what can be done to fix this issue?
Thanks,
Satish.

I have a need to embed MS-Office documents (Excel, Word) into AutoCAD using Design Automation. Searching around the web, it seems that this is not possible because the MS-Office applications, which would act as an OLE Client, would need to be running on the Forge Server. Could someone confirm that this is the case?
If I am correct in my above statement, my next best alternative would be to embed .EMF files created from each page of the document I want to embed; alternatively using raster images would also be acceptable. Creating the .EMF or raster files is not a problem. I just can't find a solution for embedding the file that does not involve copying them to the clipboard and using the PASTECLIP command. This approach has worked for me in the AutoCAD application using a C# AutoCAD.NET plugin, an OLE2Frame object is created, but it fails in accoreconsole (because PASTECLIP uses a UI class which is not available). This leads me to think that the same would occur while running the bundle in Design Automation.
The best I have been able achieve so far is to write a raster image files to the working directory and linking the raster images to the AutoCAD document using RasterImageDef and RasterImage (code below). Is this the only way I can do this? Can I do something similar using an EMF image, which is vector based, instead of a raster image? Or is there a way to actually embed an EMF (preferred) or raster image instead of just linking the images?
The code below fails if I use .EMF files, because RasterImageDef and RasterImage do not support the the EMF file; the EMF file being a vector format, not a raster format?

Raster images are always linked. There's no way to embed them. The only way to embed an image is to use AcDbOle2Frame (C++) or Autodesk.AutoCAD.DatabaseServices.Ole2Frame (C#). In theory, it is possible to create these objects without the "OLE server" being present but I haven't tried so I don't know if enough APIs are exposed to make it happen.
You should try it and see how far you can get.

There is way to embed raster image, it is not straightforeward, you need to use C++\ObjectARX API, please refer this https://github.com/MadhukarMoogala/EmbedRasterImage/tree/EmbedRasterImageUsingDBX
I am trying to synchronize a remote model with local changes.
My idea is to process changes similar to the graphModel documentation
function notifyListener(sender, event){
var codec = new mxCodec();
var changes = event.getProperty('edit').changes;
var nodesXml = [];
for (var I=0; I < changes.length; I++) {
var c = codec.encode(changes[I];
var cXml = mxUtils.getXml(c);
nodesXml.push(cXml);
}
};
graph.model.addListener(mxEvent.NOTIFY, notifyListener);
However the resulting XML data does only contain a element of ( in case of drag operation) mxGeometryChange;
e.g.
There is no more information; without a reference to the initial cell id I cannot reprocess this xml into the remote model.
I surely miss some information in the xml encoding process; but I don't see it.
Can you help out here ?

I know this is old post. But i faced similar issue.
I solved it eventually, it might help others.
In my case, folder under which I was saving the file was missing proper permission.
Please perform following task:
Right click on root folder where you are trying to save file.
Select Properties. Uncheck Read-only in attributes section.
Go to Security Tab. Select Edit > Add.
Key in "Everyone" in text box. Then Check Names > Ok.
Give "Everyone" Read, Write and Modify permission.
i need to select a video file and convert it to a byte array. the file i am trying to select has been recorded by the cameraUi interface. i can get the path to the file using
fileName = media.file.url;
readFileIntoByteArray(filePath, inBytes);
when i am passing it into the byte array i need to select directory first and then pass in the the rest of the path.
private function readFileIntoByteArray(fileName:String, data:ByteArray):void
{
var inFile:File = File.userDirectory;
inFile = inFile.resolvePath(fileName);
trace (inFile.url);
inStream.open(inFile , FileMode.READ);
inStream.readBytes(data);
}
this leads to duplication of the first part of the path.
i want to keep this dynamic as it will be run on different devices. i hard coded the file into the the variables section of flash debugger and it worked also i get an error if i leave out file.userDirectory
thanks in advance any help would be appreciated
You should always use File.applicationStorageDirectory instead of File.userDirectory. Due to security risk will vary to vary different device. File.applicationStorageDirectory will work any device.
Robust way of working with filepath
var firstPartPath:String = File.applicationStorageDirectory.nativePath;
var fullPath:String = File.applicationStorageDirectory.resolvePath("fileName.jpg").nativePath;
var expectedPath:String = fullPath.replace(firstPartPath,""); // "/fileName.jpg"
Here expectedPath value you should pass around your project instead of hard code value like c:\users\XXXX\ and save into database also use expectedPath value.
For latter access file just pass only expectedPath.
var inFile:File = File.applicationStorageDirectory.resolvePath(expectedPath);
Needn't worry about forward and backword slashes. File resolvePath() take care for you.
private function readFileIntoByteArray(fileName:String, data:ByteArray):void
{
var inFile:File = File.applicationStorageDirectory.resolvePath(fileName);
trace (inFile.url);
trace (inFile.nativePath);
trace (inFile.exists); //if file present true else false.
inStream.open(inFile , FileMode.READ);
inStream.readBytes(data);
}
Let me preface this by stating that I am not terribly familiar with ActionScript, so forgive any seemingly obvious things that I may be missing.
I current have a very simple function with an AS3 application that will output a file when a button is clicked using a FileReference object as seen below :
//Example download event
public function download(event:MouseEvent):void
{
//Build a simple file to store the current file
var outputFile:FileReference = new FileReference();
//Perform a function to build a .wav file from the existing file
//this returns a ByteArray (buffer)
downloadBuffer = PrepareAudioFile();
//Attempt to build the filename (using the length of bytes as the file name)
var fileName:String = downloadBuffer.length.toString() + ".wav";
//Save the file
audioFile.save(downloadBuffer, fileName);
}
There appears to be an error occurring somewhere within here that is resulting in the File not being outputted at all when I attempt to concatenate the file name as seen above. However, if I replace the fileName variable with a hard-coded option similar to the following, it works just fine :
audioFile.save(downloadBuffer, "Audio.wav");
Ideally, I would love to derive the duration of the file based on the length of the byteArray using the following :
//Get the duration (in seconds) as it is an audio file encoded in 44.1k
var durationInSeconds:Number = downloadBuffer.length / 44100;
//Grab the minutes and seconds
var m:Number = Math.floor(durationInSeconds / 60);
var s:Number = Math.floor(durationInSeconds % 60);
//Create the file name using those values
audioFile.save(downloadBuffer, m.toString() + "_" + s.toString() + ".wav");
Any ideas would be greatly appreciated.
Where is the problem other than missing the parentheses in m.toString()?
Aren't you missing a .lenght before the division of downloadBuffer as well?
I was finally able to come up with a viable solution that required explicit typing of all of the variables (including using a separate variable for the .toString() operations) as seen below :
public function download(event:MouseEvent):void
{
//Build a simple file to store the current file
var outputFile:FileReference = new FileReference();
//Perform a function to build a .wav file from the existing file
//this returns a ByteArray (buffer)
downloadBuffer = PrepareAudioFile();
//When accessing the actual length, this needed to be performed separately (and strongly typed)
var bufferLength:uint = downloadBuffer.length;
//The string process also needed to be stored in a separate variable
var stringLength:String = bufferLength.toString();
//Use the variables to properly concatenate a file name
var fileName:String = dstringLength + ".wav";
//Save the file
audioFile.save(downloadBuffer, fileName);
}
It's bizarre that these had to explicitly be stored within separate values and couldn't simply be used in-line as demonstrated in the other examples.
