I want to download a file in VB.net from a website that requires credentials, all my users have their credentials to this website saved in their IE settings.
Is there a way to download a file from this website using the IE credentials? I'm trying to avoid from asking my users for their credentials.
thanks.
Edit: I need to download many files, so i need a way to download the files programmatically.
just invoke this command from Process.Start:
explorer http://www......
this only works if you have the full url of the file you want to download. In case the default browser is not IE you should replace explorer with iexplore

I am trying to download (backup) images that customers upload for products that take custom logos (these are typically JPG, PNG, PDF, etc.) These customer files are downloadable by clicking on a hyperlink in the BigCommerce admin page for the order in question. The link is not a link to the image path but instead, a link to a service that sends the file to the browser. In other words, you have to be authenticated into the admin site to download the file. The URL looks like this:
https://mystore.com/internalapi/v1/orders/383945/products/251438/attributes/561518/download
https://mystore.com/internalapi/v1/orders/{order id}/products/{lineItem id}/attributes/{option id}/download
These are easily constructed in the API itself for a given order. If I use the link in a browser tab while I'm logged into the admin site, the file downloads.
But what I am trying to write an app to automatically download all the files (there are thousands). When I try to use this URL in an app, I get a authentication error. I tried at first using my regular API credentials but then used the credentials to log into the admin site. Both give me an authentication error.
I could not find anything documented on this so-called "internalapi." Anyone ever try to use this "internal" API that is used by the admin site?
I believe authentication is cookie based for that internal API, but there could be problems with using our non-publicly documented internal APIs in production, i.e. we may make future updates that would be breaking changes.
Images attached to orders through a file upload option also get copied to WebDAV, in the dav/product_images/configured_products folder. Another way to do this could be to use a WebDAV client library like easywebdav to connect and download the files.
Does anyone know how to open MS-office files without login prompt for Web DAV? I've tried editing the registry, saving the password in credential manager, etc..
however it still prompts me whenever I open up my Excel or Word file.
Note that when using windows explorer, or internet explorer, to browse files and launch for editing, this is a seperate process and executable from MS Office. The authentication state is not shared between processes, nor are cookies.
Any webdav client will display a login prompt when the web server replies to a request with a 401, which is normally after an anonymous request to a secure resource. Webdav clients will usually not send credentials pre-emptively, they send them in response to a challenge.
So to prevent the login prompt in http://milton.io we provide a framework to embed authentication tokens in the URL. This solves the problem for launching from web browsers (IE) but is not generally helpful for browsing with windows explorer.
If you are launching from windows explorer a better solution is to use a true drive mapping tool such as NetDrive.
I would like to use the Chooser drop-in to select a file from dropbox and then synchronize my app with that file occasionally in the background.
https://www.dropbox.com/developers/dropins/chooser/js
A scenario would be:
List item
User selects file.
File uploads to my app.
User returns to my app a few days later after modifying the file in dropbox.
My app should synchronize and pull down that particular file (without again displaying the Chooser drop-in).
The problem is that the Chooser provides an expiring link to the file:
"direct" is an expiring link to download the contents of the file
I can use the Core API exclusively which would work, however I would have to build my own UI to browse the user's dropbox directory. Ideally, I'd prefer to not introduce the world to another file browser; Dropbox has a file browser - and people are familiar with it. Is this possible?
Thanks,
You can just get a preview link and convert it. See https://www.dropbox.com/developers/blog/53/programmatically-download-content-from-share-links.
I have a requirement where I want HTML FTP to be accessed by AD users. When users prompted to supply their AD credentials, the IIS/FTP should mapped them directly to their folders. What I want is, an HTML "Form" page/website when its accessed from internal/external it will prompt and users will supply AD credentials. Based on the permission set on the folders users will access only their folder and will upload to their folder only. The Upload as a Browse Button which will allow them to upload specified documents to their folder only. So, When they log into their computer at work they will be able to see what has been uploaded and will be able to open that document directly.
This is actually for Part Time Lectures, currently all the shared we have on a Windows 2008 R2 and permission set based on AD.
Is this doable via HTML or any other code or FTP itself. Even third party software which will be fine too.
It might be worth taking a look at plupload - depending on your usage, you might need to pay licensing: http://www.plupload.com
I have posted some other smaller questions regarding the problem I describe below and got some feedback but now I will try to explain it in more depth hoping to get through the problem.
I built a desktop application using JavaFX 2.2 which uses a WebEngine to access a website built using Oracle ADF Pages. The application tracks the users actions on the pages and stores data to a database. All fine so far until the point where I need show a PDF file on a user click.
On the actual website the user clicks a button and a new popup window opens up that displays the PDF.
My problem is that due to the lack of PDF support in JavaFX I cannot display the pdf. The actual link to the PDF is dynamic and it doesn't have a .pdf at the end of it so I can't use the actual URL to send it to an external bowser or something to display it. Additionally the connection is secure so I can't open the URL with Chrome for example.
Possible solutions I thought about are to read the binary data of the response from WebView and create the PDF file locally and then open it using Adobe of Chrome or something. Is that possible at all?
Another solution I thought about (while I am writing this question) is maybe to open the URL which the users default browser but how can I go about sending the secure connection cookie from the application to the browser.
Is any of the above even possible? Am I missing something?
Any help, clues, links, ideas would be very much appreciated.
Thanks
I think the best way to do what you want is to download the PDF and display it locally.
Downloading using WebView sounds like it could work but I'm not familiar with the user experience. As an alternative try using curl or wget. You can pass in the authorization cookie to those tools and use them to download the file
