I'm trying implement a kind of private 'cloud store' for may web application. Let me explain, I have 'reports' (a file containing queries etc) which can be installed on a client pc. Normally, we e-mail them the files to end users whenever we create new ones and they manually import them into the app (using standard file upload in any browser).
Now we want to take it a step further and create a page which will pull a list of files from our site, eg. www.me.com/reports. The app will go through the list, compare to those installed and display new ones, updated ones etc. An end user could then just click on a button and the files are downloaded on the server and installed.
I'm trying to avoid writing any web server code, I'd prefer to just create a windows authenticated virtual directory that allows for file listing (or something close to this). I'm thinking maybe some javascript that will silently download the file to the client, then upload it back to the intranet iis server. All done without user interaction. Is this even possible?
I'd like to get anyone's thoughts on how something like this could be implemented, and what pitfalls I should watch out for.
Thanks

I have a windows server (2019) with 10 users. All the users RDP into the server to use various software applications.
Let's say users are using a program, ie. Adobe Photoshop, or Word etc (The app here does not really matter). If they want to save the document or import an image for example, a dialog comes up and it allows them to navigate the server folder structure to find the files they need.
How do I restrict them to a specific folder on a server and not allow them to navigate away from that folder using any of the file dialogs.
for example. I want to say user1 is folder1, user2 is folder2...and so on... and you cant view anything outside this folder from within the various applications? is this possible?
I'm exporting an excel file that's created dynamically at run time from DataTables in aspx.cs file at server side using ClosedXML lib. I want to let user select the downloading file location at client side, which is currently moved to downloads.
You unfortantly cannot do this. This is also why you can never select a local file or location from server side.
So, the users local file system is 100% off limits.
And the reason is quite simple. If you come to my web site to look at some cute cat picture? Well, while you are doing that, do you think it would be ok if my web code also starts looking around at your files? Hum, maybe a file called banking? Maybe a filel called passwords? Hum, how about I steal all your email files? How about I look for a Excel sheet called passwords?
So, when it comes to poking around, looking at, and deciding things like file locations? You cannot on the server side GET ANY information, nor can you even find and define what file to pick for up-loading, and the SAME applies to downloading of files. If I could pick a location, then gee, why don't I start overwriting some of your system files - including some that would give me remote access to your computer, right?
So, things like what folder, what file, even the computer name etc? These things are 100% hidden, off limits and simple not allowed. Now it would be possible for someone to come out with a new web browser tht allowed local file rights and access. But then again, no one in their right minds would ever use such a browser, and the security hole would be too large. As a result, for reasons of security, such information, and even simple knowledge of the local file system is not allowed, nor even exposed to the web server.
But then again, the user might be on a iPad, or android phone, and their file systems and how their folders works is not even the same as say a windows desktop computer anyway.
However, you can see with above, that your ability or even options to mess with, or even choose local file locations is not allowed for reasons of security.
So, if you web site provides a file, or even streams down a file, it will go into the download folder as per user browser settings - you unfortantly can't change this - it works that way due to security concerns.
Title says it simply.
I have a MS Access Database on a shared drive and the majority of users aren't experts so quite often the leave their PC with the Database open then it locks the PC, someone else will come along and switch it to their account, go to open the Database and get confused by the two files with the same name.
I can think of solutions for this e.g. using shortcuts so they dont actually see the laccdb or accdb file
But what I want to know is if there are any settings in Access (2010) that can make the .laccdb file hidden when it is created or just give it a random name like word or excel tmp files?
When I google this the results are more for removing people from the database so you can delete the laccdb file
This is actually a multi-user setup even though just one user can be active.
So you need to distribute the frontend to each user while having the backend in a folder with access for all users - that could be a subfolder of C:\Users\Public.
Here's is a script that will handle the distribution:
Deploy and update a Microsoft Access application in a Citrix environment
I'm a MS Access developer who has a client with a wordpress website. I need a way of reading any new users who are added into the wordpress site into a microsoft access database that resides on the users local machine.
I only need to add any new records and don't need to write anything back to the site.
What would be the easiest way of doing something like this? I would sooner do it from the Access side as I'm not very familiar with wordpress, also I would prefer it to be automated so the user doesn't have to manually export from wordpress then import the data every time.
Any advice appreciated.
Thanks

There's no way to have WordPress connect to an Access DB because Access isn't persistent, it's on demand. The only way I can imagine handling it would depend on Access more than anything. Assuming Access can using the ODBC connectors installed on the windows system it's running on, you could do the following:
Setup the MySQL ODBC Connector on any systems which would run the Access DB you're setting up. I assume the WordPress install is using MySQL.
Setup a new ODBC connection using that connector within Access to the Wordpress
database (you can use the same connection information stored in the
WordPress root directory in a file called wp_config.php).
If you're connecting successfully, you can then read the wp_users table using properly formatted SQL commands (select * from wp_users, for instance).
The function within Access that manages this can either be scheduled to do it periodically while Access is open or just when Access is initialized. Depending on your needs.
You'll have to compare it to a local table of users to find differences if you're interested in all changes, though the user_login is static through normal channels so it's a good key. There's also a "user_registered" date/time column in wp_users so you could just look for users who registered since your last update/change to the local access table.
I'm not familiar with Access beyond a cursory understanding of it as a data source and some minor development functions, so there may be a much easier way to do it, but this is how I'd do it in any system that needed the user information from Wordpress.
Because Wordpress and Ms-Access live in very different environments, a trick is needed to "marry" the two. Another way we can use:
Use IIS as a webserver, so as not to collide with the port used by wordpress, so don't use port 80. Just use any port.
Use ASP to access Access Database (of course there is a block of ASP code to activate the connector to the Access file, then create a recordset via that connector for record2 and display it to the browser). Call it with the file name: recordshower.asp
The recordshower.asp file must be able to be called by the browser.
After that, go back to a page in wordpress, insert <iframe src=recordshower.asp width:.... ></iframe>
So, a wordpress page can display the contents of an Access table, with the help of ASP
I export the WordPress entries to a .CSV, I then run an Excel macro, which is stored in my personal workbook, to open the file from my downloads directory, convert the .CSV to .XLS, and write it to an XLS file in a known location. I then push a button in my MS Access program to read the entries from the .XLS file (which is externally linked to my MS Access as a Excel spreadsheet) and update my MS Access tables with the data.
I have a web page where i have an ASP.NET file upload control to upload files from client machine to Server.Now i want to do the uploading n number of times.Ex : I want to upload 100 files from my local pc to server.The 100 file names i can read from an excel file in my program.But is there any way to assign this file to the file upload control ?
No, as a security feature, FilUpload controls do not allow you to set what to download (imagine if you sign on to a website, and it is set to upload a passwords file or something).
Now there is probably another control, or a way to code around this, buut the FileUpload control will not allow it.
I would recommend using the jQuery Multifile Uploader which would take care of a UI (if you need one). And the actual uploads with Free ASP Uploads which takes care of the actual file transfer. Though it sounds like you are tkaing care of the programs programatically, so you can skip the multifule and just work with free asp upload.
You'll have to make your own Flash object or something to accomplish this, the basic HTML/ASP.Net controls won't let you do what you're looking for.
This will require creating some kind of an active or installable control. In order to get around the security hole of doing this, you're ultimately going to have to be able to execute code on the machine to select and upload the file.
And at that point, you're platform specific, so...
I would strongly suggest that instead of trying to have a web site automatically upload files for you, that you make a WinForms utility to accomplish this task and upload the files wherever you need, communicate with the web site over web services, etc.
This is a security restriction, you cant script the file selection of an upload box as it would allow hackers to write scripts to steal files off your computer.
You could use this silverlight upload utility which is my list of "things to use when I get the chance".
It has a nice UI and supports uploading many files at once. I originally tracked it down doing some research for a photography website that we were quoting for but that project fell through.
Anyway the project can be found here:

It also has full source code included so even if the control's developers abandon it you still have the choice to edit it yourself.
