[ASP.NET c#] Local Folder Browsing?


Question

Hi Guys,

Started a major porject at my Work Placement of creating a locally hosted asp.net application. One of the things I decided to do on it is, instead of the user actually typing the folder path into a textbox, I would like the users to just click a browse button and then a tree view type browser appear, and then he/she just points the the directory, so that the details that he/she is working on at the moment can be saved locally.

Beacuse I've only just started to learn asp[vbs] classic about a month ago, let alone asp.net[c#], I'm not that clued up on how to do it? can one of you guys please help me out, and explain the steps and objects i need to use.

thanks matt

The best place to start would be to look into the DirectoryInfo and FileInfo classes in the System.IO namespace.

They give you the ability to enumerate directories and files, find out meta information etc.

The other thing you need to consider is security on your application, so you will also need to look at things like IIS Security, and ASP.NET Security and how they work together.

Saving to a local folder from a browser is a privileged operation, so programmatically scanning a client's drive via a browser isn't something I'd ever recommend(you'd need a client technology like ActiveX to do it anyway, and lower security for that control). What you might do is have the user click a "Save" button that would post their work to the server, which would then put the information into a file format and respond it back to the user prompting them to save it somewhere locally via the typical browser 'File Save' dialog. I do something similar when users want to export datagrids to Excel, so I know it is viable.

Ah, I didnt read the 'locally' part. azcodemonkey is correct, you would need to leverage some sort of ActiveX control. I wrote one myself for part of an intranet project to allow me to do drag-drop file uploads from the client browser. If it is an internal (read; Intranet-only) application you are writing, I wouldnt see any issues with deploying your control to client machines.

Use AJAX instead of postback.

    • For anyone looking for a lightweight formatting-free text editor, I recommend Notepad3.
    • This looks really dumb, especially if it costs $100+. Noone who cares about using a flight yoke would touch that thing, people who don't care are probably fine using the analog sticks on their controller, so who is it for?
    • A) "they shouldn't be making money off of those [free videos]"?? That is literally their business model, making money off videos that users post...if you don't feel like that should be allowed, then are you saying YouTube shouldn't exist. B) Yes, the example I gave is a net-negative transaction. If YouTube makes money from others who are following their rules, it doesn't change the fact that the person using an ad-blocker is costing them money. C) YouTube has always operated at a loss...kind of invalidates your entire argument. As I always say, I don't care what you do, I will not even say you are wrong for doing it. That is purely your choice. Just be honest enough to say something like "Google is rich, I honestly don't care." Perfectly fine reason. Don't act like there is some imagined justification for why it isn't breaking the rules.
    • You can now present content from your camera feed in Google Meet by David Uzondu Google has a new feature rolling out for Google Meet that lets you directly present video from an external camera feed right into your meetings. This means if you have a document camera for showing physical papers, a dedicated external camera for a better angle, or even output from a video production tool, you can now pipe that into Meet as a presentation source. This new option supports video up to 1080p at 30FPS. This "present from camera" function offers a more integrated way to handle certain video inputs compared to some existing workarounds. For instance, it might prove less complicated than a setup with OBS Studio where you arrange your various video sources into scenes, activate the virtual camera output, and then navigate Google Meet's settings to specifically choose "OBS Virtual Camera" as your video input before you can even start presenting that customized feed. Alongside this camera presentation feature, Google's announcement also mentioned several improvements to the general screen sharing experience in Meet. Initiating any type of screen share is faster now, and video quality during screen sharing has also been sharpened, with better handling of dynamic content like scrolling text or embedded videos. To reduce interruptions, if a second presenter stops sharing their screen, any previous presentation will now automatically resume. For those wondering when they can get their hands on this, the rollout for the camera presentation feature and these screen sharing enhancements has begun for Rapid Release domains. Users on Scheduled Release domains will start seeing it from June 11, 2025. Google notes that it could take up to 15 days for these features to be visible to all eligible users. Most Google Workspace accounts, including Business Standard and Plus, various Enterprise and Education tiers, and Workspace Individual subscribers, will have access. This new presentation option joins other recent Google Workspace enhancements. For instance, Gemini in Google Drive can now summarize changes to your files, offering a quick way to get updated on what you missed in documents since you last opened them.
