View 1 RepliesI had an exercise where I was supposed to have a button open an openfile dialog box, let the user select a file, then another button that would save the file with the extension ".bak". The author didn't give any clues about manipulating extensions -- but a few chapters back we covered string functions. So, with that in mind, I did the following...
Private Sub btnSaveFile_Click(sender As System.Object, e As System.EventArgs) Handles btnSaveFile.Click

Ive created a simple application that works fine when i debug and test it though visual studio but when i deploy the application, download it and install it onto my machine i get an error.basically when the first form loads it checks for a file called "New Folder" in my program files folder on my machine if the file is not there, then it adds the file. the code im using to do this is:
If System.IO.Directory.Exists(My.Computer.FileSystem.SpecialDirectories.ProgramFiles & "New Folder") Then

I have an application where the admin user can create users and upload documents to the server for the created user to download.
When uploading a file it creates a folder using the userid as the folder name and saves in that folder within a folder called documents e.g. ~documents/77b29079-43d6-4520-bc34-77ae2af1b131/documentname.xls
The client then has to login and will see a list of available documents for that user only. The only problem is that if someone was to get hold of one of the urls to a document is can be downloaded without having to login.
Is there something I can do to stop access to these files?? I have tried editing the web.config file to only allow access to certain roles but i could still download a document without logging in.

And when I do, I get the error "The remote server returned an error: {401} Unauthorised.", but I shouldn't need any credentials to access this. I'm just trying to POST a username and password to that page and have it query the database and then get the returned content, I'd prefer to use POST than GET so you can't see the user/pass in the URL (if possible).
EDIT: I used CPanel to password protect my website so it can't be accessed, after supplying my user & pass to access it, everything works.
I have my own login page.If any user access any page directly(without login),i want to redirect unauthorized user to login page. Using Generic Handler is there any chance?

If any directory within a set being searched by the [URL] or [URL] methods contains a junction point, the entire method fails and returns zero results on my tests under VB 2008. I would like to make the call more robust: to return the folders or files not blocked by access restrictions and to note the folders which were blocked. Do those methods offer a means to do this, or is a recursive folder-by-folder call necessary?

I'm trying to write a console application that can modify registry subkeys on remote pc's in the same network. I have it working in my own environment but when I install on the customer machines I'm getting unauthorized access when it hits the OpenRemoteBaseKey. The security settings in the application properties is set to full trust application so I'm not sure why it won't work.
I'm using Visual Studio 2010 and first I just installed it on the customer machine and when it wouldn't work I ran the source code in Visual Studio 2005 which is on the customer machine but got same results.I can run the app directly on the remote machine and it will change the registry subkeys as directed, I just can't do it remotely. RemoteRegistry service is started. Both machines are logged in as administrators.
Here is the source code:

My.Computer.Registry.SetValue _

I'm getting error "Unauthorized Access Exception was unhandled."
"Access to the registry key 'HKEY_LOCAL_MACHINE....' is denied."
I've googled the net and found that registry permission elevation is required for admin tasks, Is there away to take registry key ownership through VB.Net code??

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.
