Not able to get file object Using YUI IN Internext Explorer - file-upload

I am trying to upload a file using YUI.
Below is my code that works fine in Firefox and Chrome.But not working in IE 8.
this.portlet_view_object.delegate('change', function(e) {
......
var fileField = Y.one('#newcase_file_'+context.imageCount);
var file = fileField._node.files[0];
if(!context.maxFileSize.call(context,file)){
return;
}
....
Here, the maxFileSize, is the method to which i pass the file object and perform operation related to fiel(e.g. fileSize, fileName).
In firefox and chrome, i am getting the file object by fileField._node.files[0];
But the same thing is not working in IE 8,and getting below error.
_node.files.0' is null or not an object
Any suggestions are welcomed.
Thanks.

This issue isn't related to YUI, just to IE.
.files holds multiple selected files, but IE8 does not support this methos and can only select one file. Therefore this property isn't recognized.
You can use this workaround:
if ('files' in fileField._node)
var file = fileField._node.files[0];
else
var file = fileField._node.value;
Or skip the whole .files completely if you want to, although I personally wouldn't recommend it.

Save an image present in PDF on local File System

This is my first experience of using PDFBox jar files. Also, I have recently started working on TestComplete. In short, all these things are new for me and I have been stuck on one issue for last few hours. I will try to explain as much as I can. Would really appreciate any help!
Objective:
To save an image present in a PDF file on the file system
Issue:
When this line gets executed objImage.write2file_2(strSavePath);, I get the error Object doesn't support this property or method.
I am taking some help from here
Code:
function fn_PDFImage()
{
var objPdfFile, strPdfFilePath, strSavePath, objPages, objPage, objImages, objImage, imgbuffer;
strPdfFilePath = "C:\\Users\\aabb\\Desktop\\name.pdf";
strSavePath = "C:\\Users\\aabb\\Desktop\\abc";
objPdfFile = JavaClasses.org_apache_pdfbox_pdmodel.PDDocument.load_3(strPdfFilePath);
objPages = objPdfFile.getDocumentCatalog().getAllPages();
//getting a page with index=1
objPage = objPages.get(1)
objImages = objPage.getResources().getXObjects().values().toArray();
Log.Message(objImages.length); //This is returning 14. i.e, 14 images
//getting an image with index=1
objImage = objImages.items(1);
Log.Message(typeof objImage); //returns "Object" which means it is not null
//saving the image
objImage.write2file_2(strSavePath); //<---GETTING AN ERROR HERE
}
ERROR:
If you are bothered about the method namewrite2file_2, please read this excerpt from the link which I have shared:
In Java, the constructor of a class has the name of this class.
TestComplete changes the constructor names to newInstance(). If a
class has overloaded constructors, TestComplete names them like
newInstance, newInstace_2, newInstance_3 and so on.
Additional Info:
I have imported Jar file(pdfbox-app-1.8.13.jar) and their classes in testcomplete. I am not sure if I need to import some other jar file or its class here:
XObjects are not always image XObjects. And write2file is in the class PDXObjectImage so you need to check your object type first.
Re the second question asked in the comment: the form XObject isn't something you can save. XObject forms are content streams with resources etc, similar to pages. However what you can do is to explore these too whether the resources have images. See how this is done in the ExtractImages source code of PDFBox 1.8.
However there are other places where there can be images (e.g. patterns, soft masks, inline images); this is only available in PDFBox 2.*, see the ExtractImages source code there. (Note that the class names are different).

Using Leigh version of S3Wrapper.cfc Can't get past Init

I am new to S3 and need to use it for image storage. I found a half dozen versions of an s2wrapper for cf but it appears that the only one set of for v4 is one modified by Leigh
https://gist.github.com/Leigh-/26993ed79c956c9309a9dfe40f1fce29
Dropped in the com directory and created a "test" page that contains the following code:
s3 = createObject('component','com.S3Wrapper').init(application.s3.AccessKeyId,application.s3.SecretAccessKey);
but got the following error :
So I changed the line 37 from
variables.Sv4Util = createObject('component', 'Sv4').init(arguments.S3AccessKey, arguments.S3SecretAccessKey);
to
variables.Sv4Util = createObject('component', 'Sv4Util').init(arguments.S3AccessKey, arguments.S3SecretAccessKey);
Now I am getting:
I feel like going through Leigh code and start changing things is a bad idea since I have lurked here for year an know Leigh's code is solid.
Does any know if there are any examples on how to use this anywhere? If not what I am doing wrong. If it makes a difference I am using Lucee 5 and not Adobe's CF engine.
UPDATE :
I followed Leigh's directions and the error is now gone. I am addedsome more code to my test page which now looks like this :
<cfscript>
s3 = createObject('component','com.S3v4').init(application.s3.AccessKeyId,application.s3.SecretAccessKey);
bucket = "imgbkt.domain.com";
obj = "fake.ping";
region = "s3-us-west-1"
test = s3.getObject(bucket,obj,region);
writeDump(test);
test2 = s3.getObjectLink(bucket,obj,region);
writeDump(test2);
writeDump(s3);
</cfscript>
Regardless of what I put in for bucket, obj or region I get :
JIC I did go to AWS and get new keys:
Leigh if you are still around or anyone how has used one of the s3Wrappers any suggestions or guidance?
UPDATE #2:
Even after Alex's help I am not able to get this to work. The Link I receive from getObjectLink is not valid and getObject never does download an object. I thought I would try the putObject method
test3 = s3.putObject(bucketName=bucket,regionName=region,keyName="favicon.ico");
writeDump(test3);
to see if there is any additional information, I received this :
I did find this article https://shlomoswidler.com/2009/08/amazon-s3-gotcha-using-virtual-host.html but it is pretty old and since S3 specifically suggests using dots in bucketnames I don't that it is relevant any longer. There is obviously something I am doing wrong but I have spent hours trying to resolve this and I can't seem to figure out what it might be.
I will give you a rundown of what the code does:
getObjectLink returns a HTTP URL for the file fake.ping that is found looking in the bucket imgbkt.domain.com of region s3-us-west-1. This link is temporary and expires after 60 seconds by default.
getObject invokes getObjectLink and immediately requests the URL using HTTP GET. The response is then saved to the directory of the S3v4.cfc with the filename fake.ping by default. Finally the function returns the full path of the downloaded file: E:\wwwDevRoot\taa\fake.ping
To save the file in a different location, you would invoke:
downloadPath = 'E:\';
test = s3.getObject(bucket,obj,region,downloadPath);
writeDump(test);
The HTTP request is synchronous, meaning the file will be downloaded completely when the functions returns the filepath.
If you want to access the actual content of the file, you can do this:
test = s3.getObject(bucket,obj,region);
contentAsString = fileRead(test); // returns the file content as string
// or
contentAsBinary = fileReadBinary(test); // returns the content as binary (byte array)
writeDump(contentAsString);
writeDump(contentAsBinary);
(You might want to stream the content if the file is large since fileRead/fileReadBinary reads the whole file into buffer. Use fileOpen to stream the content.
Does that help you?

File download control - delete file without validation?

Hello XPages programmers.
I work on a simple XPages File Library.
To achieve that i use FileUpload control with FileDownload control.
When i create a new file, i enter its name, and select a file.
I set that uploading a file won't activate a validation, so i can attach a file without a specified name. Additionally i set it to do fullrefresh, so uploading a file takes place in an instant and a file is visible in FileDownload control.
Problem occurs, when i want to delete that attachment using garbage icon of FileDownload - i can't set it to run without walidation.
Is there any workaround avaiable?
Any help will be appreciated.
I used the workaround Mark Leusink suggested - created a simmilar button (used image from filedownload control) and then set it for full refresh with process data without validation property.
Code in JSSS
function deleteAttachments()
{
var attList = dDocument.getAttachmentList("Document_Attachment");
for(var i=0; i<attList.size(); i++)
{
var att:String = attList[i];
dDocument.removeAttachment("Document_Attachment", att.getName() );
}
}
Surely it can be used for delete a specific attachment by getting attachment name from rowdata in a repeater and use DATASOURCE.removeAttachment method.
Thanks for your support!

an error 3013 thrown when writing a file Adobe AIR

I'm trying to write/create a JSON file from a AIR app, I'm trying not so show a 'Save as' dialogue box.
Here's the code I'm using:
var fileDetails:Object = CreativeMakerJSX.getFileDetails();
var fileName:String = String(fileDetails.data.filename);
var path:String = String(fileDetails.data.path);
var f:File = File.userDirectory.resolvePath( path );
var stream:FileStream = new FileStream();
stream.open(f, FileMode.WRITE );
stream.writeUTFBytes( jsonToExport );
stream.close();
The problem I'm having is that I get a 'Error 3013. File or directory in use'. The directory/path is gathered from a Creative Suite Extension I'm building, this path is the same as the FLA being developed in CS that the Extension is being used with.
So I'm not sure if the problem is that there are already files in the directory I'm writing the JSON file to?
Do I need to add a timer in order to close the stream after a slight delay, giving some time to writing the file?
Can you set up some trace() commands? I would need to know what the values of the String variables are, and the f.url.
Can you read from the file that you are trying to write to, or does nothing work?
Where is CreativeMakerJSX.getFileDetails() coming from? Is it giving you data about a file that is in use?
And from Googling around, this seems like it may be a bug. Try setting up a listener for when you are finished, if you have had the file open previously.
I re-wrote how the file was written, no longer running into this issue.

How to Implement callback for file downloading?

I wrote a script that downloads file from web using file URL. I have an ActiveXObject of following type.
var objHTTP = new ActiveXObject("MSXML2.XMLHTTP");
objHTTP.open("GET", strFileURL, false);
It works perfect for small size file says, file size less than 100MB. But when I try to download file with size greater than 100MB my script hanged. Then I tried,
objHTTP.open("GET", strFileURL, true);
but in this case we have to implement a callback function. I don't know how to implement callback and then use it. Can somebody help me. I am using TestComplete 7. Script that I wrote;
var objHTTP = new ActiveXObject("MSXML2.XMLHTTP");
objHTTP.open("GET", strFileURL, true);
objHTTP.onreadystatechange = Callback;
objHTTP.send();
while((objHTTP.readyState != 4) && (objHTTP.readyState != 'complete'))
{
Delay(100);
}
if(200 != objHTTP.Status)
{
Log.Error("The " + strFileURL + " file was not found." + " The returned status is " + objHTTP.Status);
return;
}
I don't know how to implement Callback function. Can somebody provide me implementation?
Thanks
Probably, the hanging is the result of the while loop waiting for a specific value of the readyState property. If the property never gets one of the expected values, the script will work forever.
I think the MSXML2.XMLHTTP object fails to load the large file, and never sets the readyState to one of the values your script expects. To understand what exactly is happening, I would check what value the property has after very long time, which is enough either for the file to load, or for the attempt to fail (say, 2 hours). If you know what value the readyState property has when the downloading fails, you can handle it in the script to avoid hanging.
That's it about the hanging itself. Now about the cause of the file downloading problem. I have found a page that tells about the problem and suggests setting higher timeouts - take a look:
http://edgylogic.com/blog/downloading-large-files-vbscript/
The example is in VBScript, but it should be easy to implement the same approach with JScript. Please note that the example uses a different COM object - ServerXMLHTTP. You can read about it (including differences from XMLHTTP) here:
http://msdn.microsoft.com/en-us/library/ms762278(v=VS.85).aspx
I hope this helps.
