I'm opening a word document through IE on a local network, it opens up fine but if a document is password protected then it should prompt for the password which it doesn't.
Is there something that I should be doing to get the password prompt?
The way I'm opening the document is by a link on a web page e.g.
Document
I've got what I want working using the following javascript/jQuery.
jQuery is not required, I used it as I already have it as part of the project.
$('a.openDoc').live('click',function(){
var file = $(this).attr('href');
// This is what does the work.
try
{
try
{
// get Word Active-X Object if Word is open.
var word = GetObject('',"Word.Application");
}
catch(e)
{
// create new Word Active-X Object.
var word = new ActiveXObject("Word.Application");
}
word.Visible = true; // Make sure Word is visible.
word.Documents.Open(file); // Open the file you want.
}
catch(e)
{
alert(e.description);
}
// End work.
return false;
});
In case you are ok with having the document open in Word itself (and not in IE), maybe this will point you in the right direction:

I have a lot of picture links in my Google Sheet:
https://drive.google.com/file/d/1BDj24_6uz-ZQlGWLy0o1_DES6tJI3NMu/view?usp=sharing
I want to get the filename behind the link. When i open the link and save the image the image filename is: "FILENAME.jpg" or something similar
I want to get this information in Sheets.
How can i do that?
An Apps Script Solution
Thanks to #Tanaike for obtaining clarifications in the comments.
First enter your links in the format shown below in a Google Sheet.
The name of the titles is not important, but this particular script starts getting names from the 2nd row.
If you don't know how to create a script, there are tutorials here offered by Google. You should create the script from the same Sheet. That is, from the menu in the Sheet:
In the script editor, copy and paste the following code:
function getNames() {
var activeRange = SpreadsheetApp.getActiveSheet().getDataRange();
var height = activeRange.getHeight();
var links = SpreadsheetApp.getActiveSheet()
.getRange("A2:A" + height)
.getValues();
var nameValues = [];
links.forEach((row) => {
try {
var link = row[0];
var fileID = getIdFromLink(link);
var name = DriveApp.getFileById(fileID).getName();
nameValues.push([name]);
} catch (e) {
nameValues.push(["NO NAME FOUND"]);
}
});
var nameRange = SpreadsheetApp.getActiveSheet().getRange("B2:B" + height);
nameRange.setValues(nameValues);
}
function getIdFromLink(link) {
var regex = new RegExp(
/(?<=https:\/\/drive\.google\.com\/file\/d\/)(.+)(?=\/)/
);
return regex.exec(link)[0];
}
Run the getNames function. The first time it will ask you to grant some permissions, grant them. Then it should fill in the files names.

I really love the DropZoneJS component and am currently wrapping it in an EmberJS component (you can see demo here). In any event, the wrapper works just fine but I wanted to listen in on one of Dropzone's events and introspect the file contents (not the meta info like size, lastModified, etc.). The file type I'm dealing with is an XML file and I'd like to look "into" it to validate before sending it.
How can one do that? I would have thought the contents would hang off of the file object that you can pick up on many of the events but unless I'm just missing something obvious, it isn't there. :(
This worked for me:
Dropzone.options.PDFDrop = {
maxFilesize: 10, // Mb
accept: function(file, done) {
var reader = new FileReader();
reader.addEventListener("loadend", function(event) { console.log(event.target.result);});
reader.readAsText(file);
}
};
could also use reader.reaAsBinaryString() if binary data!
Ok, I've answer my own question and since others appear interested I'll post my answer here. For a working demo of this you can find it here:
https://ui-dropzone.firebaseapp.com/demo-local-data
In the demo I've wrapped the Dropzone component in the EmberJS framework but if you look at the code you'll find it's just Javascript code, nothing much to be afraid of. :)
The things we'll do are:
Get the file before the network request
The key thing we need become familiar with is the HTML5 API. Good news is it is quite simple. Take a look at this code and maybe that's all you need:
/**
* Replaces the XHR's send operation so that the stream can be
* retrieved on the client side instead being sent to the server.
* The function name is a little confusing (other than it replaces the "send"
* from Dropzonejs) because really what it's doing is reading the file and
* NOT sending to the server.
*/
_sendIntercept(file, options={}) {
return new RSVP.Promise((resolve,reject) => {
if(!options.readType) {
const mime = file.type;
const textType = a(_textTypes).any(type => {
const re = new RegExp(type);
return re.test(mime);
});
options.readType = textType ? 'readAsText' : 'readAsDataURL';
}
let reader = new window.FileReader();
reader.onload = () => {
resolve(reader.result);
};
reader.onerror = () => {
reject(reader.result);
};
// run the reader
reader[options.readType](file);
});
},
https://github.com/lifegadget/ui-dropzone/blob/0.7.2/addon/mixins/xhr-intercept.js#L10-L38
The code above returns a Promise which resolves once the file that's been dropped into the browser has been "read" into Javascript. This should be very quick as it's all local (do be aware that if you're downloading really large files you might want to "chunk" it ... that's a more advanced topic).
Hook into Dropzone
Now we need to find somewhere to hook into in Dropzone to read the file contents and stop the network request that we no longer need. Since the HTML5 File API just needs a File object you'll notice that Dropzone provides all sorts of hooks for that.
I decided on the "accept" hook because it would give me the opportunity to download the file and validate all in one go (for me it's mainly about drag and dropping XML's and so the content of the file is a part of the validation process) and crucially it happens before the network request.
Now it's important you realise that we're "replacing" the accept function not listening to the event it fires. If we just listened we would still incur a network request. So to **overload* accept we do something like this:
this.accept = this.localAcceptHandler; // replace "accept" on Dropzone
This will only work if this is the Dropzone object. You can achieve that by:
including it in your init hook function
including it as part of your instantiation (e.g., new Dropzone({accept: {...})
Now we've referred to the "localAcceptHandler", let me introduce it to you:
localAcceptHandler(file, done) {
this._sendIntercept(file).then(result => {
file.contents = result;
if(typeOf(this.localSuccess) === 'function') {
this.localSuccess(file, done);
} else {
done(); // empty done signals success
}
}).catch(result => {
if(typeOf(this.localFailure) === 'function') {
file.contents = result;
this.localFailure(file, done);
} else {
done(`Failed to download file ${file.name}`);
console.warn(file);
}
});
}
https://github.com/lifegadget/ui-dropzone/blob/0.7.2/addon/mixins/xhr-intercept.js#L40-L64
In quick summary it does the following:
read the contents of the file (aka, _sendIntercept)
based on mime type read the file either via readAsText or readAsDataURL
save the file contents to the .contents property of the file
Stop the send
To intercept the sending of the request on the network but still maintain the rest of the workflow we will replace a function called submitRequest. In the Dropzone code this function is a one liner and what I did was replace it with my own one-liner:
this._finished(files,'locally resolved, refer to "contents" property');
https://github.com/lifegadget/ui-dropzone/blob/0.7.2/addon/mixins/xhr-intercept.js#L66-L70
Provide access to retrieved document
The last step is just to ensure that our localAcceptHandler is put in place of the accept routine that dropzone supplies:
https://github.com/lifegadget/ui-dropzone/blob/0.7.2/addon/components/drop-zone.js#L88-L95
using the FileReader() solution is working amazingly good for me:
Dropzone.autoDiscover = false;
var dz = new Dropzone("#demo-upload",{
autoProcessQueue:false,
url:'upload.php'
});
dz.on("drop",function drop(e) {
var files = [];
for (var i = 0; i < e.dataTransfer.files.length; i++) {
files[i] = e.dataTransfer.files[i];
}
var reader = new FileReader();
reader.onload = function(event) {
var line = event.target.result.split('\n');
for ( var i = 0; i < line.length; i++){
console.log(line);
}
};
reader.readAsText(files[files.length-1]);
I am making a Windows Store application and I want to allow users that press an "Export To Word" button to have all the data that they have input into the app to be displayed in a Word document and saved to a desired location on their computer. The code below is a test segment of code that almost does what I am after, however after saving the document and opening it using Word rather than the app, it cannot open the file due to it being corrupted apparently. However when you open it in Notepad the text is displayed as I want.
private async void exportToWord_Click(object sender, RoutedEventArgs e)
{
await ExportToWord();
}
private async Task ExportToWord()
{
// Create the picker object and set options
Windows.Storage.Pickers.FileSavePicker savePicker = new Windows.Storage.Pickers.FileSavePicker();
savePicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.DocumentsLibrary;
// Dropdown of file types the user can save the file as
savePicker.FileTypeChoices.Add("Word", newList<string>{".docx"});
// Default file name if the user does not type one in or select a file to replace
savePicker.SuggestedFileName = "Test";
Windows.Storage.StorageFile file = await savePicker.PickSaveFileAsync();
MessageDialog mD;
if (file != null)
{
// Prevent updates to the remote version of the file until we finish
// making changes and call CompleteUpdatesAsync.
Windows.Storage.CachedFileManager.DeferUpdates(file);
// write to file
await Windows.Storage.FileIO.WriteTextAsync(file, createContentsOfFile());
// Let Windows know that we're finished changing the file so the other
// app can update the remote version of the file.
// Completing updates may require Windows to ask for user input.
Windows.Storage.Provider.FileUpdateStatus updateStatus = await Windows.Storage.CachedFileManager.CompleteUpdatesAsync(file);
if (updateStatus == Windows.Storage.Provider.FileUpdateStatus.Complete)
{
mD = newMessageDialog("Connect exported to:" + file, "Export Successful");
}
else
{
mD = newMessageDialog("Could not save file. Try again", "Export Unsuccessful");
}
}
else
{
mD = newMessageDialog("Operation canceled because the file could not be found. Try again", "Export Unsuccessful");
}
await mD.ShowAsync();
}
private string createContentsOfFile()
{
return "Testing...";
}
I believe the issue is that I am outputting plain text to the Word document but it needs to be in a certain format to be output correctly and be displayed in a Word doc. Is there any way of doing this in Windows Store apps?
Any help would be appreciated.
I'm not aware of any Word doc components available for Windows Runtime apps (Microsoft doesn't provide one, but there could be a third party component I'm not aware of).
You can get documentation on the docx format and for simple text it may not be too complex (I'm not sure), or you can use another format which Word can open.
If you don't need formatting I'd probably stick with txt.
If you need small amounts of formatting then rtf is a good option. It is fairly simple to generate yourself or the RichEditBox can export RTF format text which you can then save into a .doc file and open in Word.
Is there a way to detect if a particular file that is being downloaded is a Gmail attachment?
I am looking for a way to write a Greasemonkey script which would help me organize the downloads, based on their download sources, say Gmail email attachments would have a different behavior from other stuff.
So far, I've found out that attachments redirect to https://mail-attachment.googleusercontent.com/attachment/u/0/ , which I guess is not sufficient.
EDIT
Since an add-on would be more powerful than a userscript, I've decided to pursue the Add On idea. However, the problem of detection remains unsolved.
This is too complicated for just one question; it has at least these major parts:
Do you want to redirect downloads when the user clicks, or automatically download select files? Clarify the question.
Your GM script must identify the appropriate download links, and on which pages, and for which views? For gMail, this is not a trivial task, and the question needs to be clearer. It's worthy of a whole question just on this issue given the variety of views and AJAX involved.
Once identified, the script probably needs to intercept clicks on those links. (Depends on your goal (clarify!) and what the Firefox extension can do.)
Greasemonkey needs to interact with an extension that either intercepts the user-initiated download, or allows for an automatic download. I've detailed the auto-download approach, below.
Once your script has identified the appropriate file URLs and/or links (Open a new question for more help with that, and include pictures of the types of pages and links you want.), it can interface with a Firefox add-on, like the one below, to automatically save those files.
Automatically saving files from Greasemonkey with the help of an additional Add-on:
WARNING: The following is a working proof of concept for education only. It has no security features, and if you use it as-is, for actual surfing, some webpage or script writer or extension writer will use it to completely pwn your computer.
If you use the Add-on builder or SDK to install or "Test" the DANGER. DANGER. DANGER. File download utility,
Then you can use a Greasemonkey script, like this, to automatically save files:

var fileURL = "http://userscripts.org/scripts/source/29222.user.js";
var savePath = "D:\\temp\\";
var extensionLoaded = false;
window.addEventListener ("ImAlivefromExtension", function (zEvent) {
console.log ("The test extension appears to be loaded!", zEvent.detail);
extensionLoaded = true;
} );
window.addEventListener ("ReplyToDownloadRequest", function (zEvent) {
//var xxxx = JSON.parse (zEvent.detail);
console.log ("Extension replied: ", zEvent.detail);
} );
$("body").prepend ('<button id="gmFileDownloadBtn">Click to File download request.</button>');
$("#gmFileDownloadBtn").click ( function () {
if (extensionLoaded) {
detailVal = JSON.stringify (
{targFileURL: fileURL, targSavePath: savePath}

var zEvent = new CustomEvent (
"SuicidalDownloadRequestToAddOn",
{"detail": detailVal }
);
window.dispatchEvent (zEvent);
}
else {
alert ("The file download extension is not loaded!");
}
} );
You can test the script on this SO question page.
Note that any other extension, userscript, web page, or plugin can listen to or send spoof events, the only security, so far, is to limit which pages the extension runs on.
For reference, the extension source files are below. The rest is supplied by Firefox's Add-on SDK.
The content script:
var zEvent = new CustomEvent ("ImAlivefromExtension",
{"detail": "GM, DANGER, DANGER, DANGER, File download utility" }
);
window.dispatchEvent (zEvent)
window.addEventListener ("SuicidalDownloadRequestToAddOn", function (zEvent) {
console.log ("Extension received download request: ", zEvent.detail);
//-- Relay request to extension main.js
self.port.emit ("SuicidalDownloadRequestRelayed", zEvent.detail);
//-- Reply back to GM, or whoever is pretending to be GM.
var zEvent = new CustomEvent ("ReplyToDownloadRequest",
{"detail": "Your funeral!" }
);
window.dispatchEvent (zEvent)
} );

So far from what you are saying,the only thing you can do is making add-on(Firefox) and Extension(for chrome if you want).
If you have closer look at download of attachment,it happens when:
1) You click on icon of attachments
2) If you click download
For these two things you can find the click event of <a> tag containing download_url value.You can easily do that using js/jquery for creting extension.
So you can write the functionality when user tries to download attachment.
You could use Gmail contextual gadgets to modify the behavior on the Google side:
Gmail Contexual Gadgets
Contextual Gadgets don't have direct access to attachments but server side, you could use IMAP to access the attachment (based on the Gmail message ID identified by the gadget):
Gmail IMAP Extensions
Using gadgets and server-side IMAP has the advantage of being browser-agnostic.
It's not entirely clear what you want to do differently with the downloaded Gmail attachment as opposed to any given download (save it to a different location? Perform actions upon the attachment data?) But the contextual gadget and IMAP should give you some chance to modify the attachment data as needed before the browser download begins.
I have a requirement to download a file from the server, but open inline if possible. I'm currently doing;
Response.AddHeader("Content-Disposition", string.Format("inline; filename={0}", documentFileName));
result = new FileStreamResult(new FileStream(documentFilePath, FileMode.Open), "application/msword");
I've put application/msword in there right now, because that's what I'm having a problem with. When I click Open on the word document, it's as if the document makes multiple calls back to the action, but there is no session and no database so it crashes. When the user is running this, they see a long hang, the "Downloading" dialog finally appears in word and they have to cancel it. The document is there and is valid but this is not desirable.
Pdfs, pngs etc. download fine. Can anybody explain this behavior, and give me some hints as to how I fix it?
Update:
The action basically looks like;
[HttpPost]
public FileResult View(int id, int source)
{
var document = GetDocumentFromDatabase(id, source);
documentFilePath = Path.Combine( documentsDirectory, document.Name);
documentName = document.Name;
Response.AddHeader("Content-Disposition", string.Format("inline; filename={0}", documentFileName));
result = new FileStreamResult(new FileStream(documentFilePath, FileMode.Open), "application/msword");
return result;
}
I've trimmed it down, as I can't share the specifics, but the full idea is there.
Answer:
I have a lookup of available content-types, in there I have defined whether the file is inline or attachment, and when I detect a word document, I set it to attachment. No more error. PDF opens in the browser still because I set it to inline.
I use:
public ActionResult GetAttachment(int id)
{
var attachment = _repository.GetAttachByID(id);
if (attachment != null)
{
Response.AppendHeader("Content-Disposition",string.Format("inline; filename={0}",attachment.FileName));
return File(attachment.File, attachment.MimeType, attachment.FileName);
}
else
{
return null;
}
}
