Re: retrive client logical drives in alternative of Directory.GetLogicalDrive which used in server side

1-Jun-10 23:45

hi, everybody..
I want to retrieve client drives (in short file manager).
Actually i am trying with Directory.GetLogicalDrive() function, but its returns logical drive of the server in which asp.net website is installed. i want logical drives from client PC..
i.e. i want to client to be select some files or folder from own PC and by that path i upload whole folder or files without using fileupload control limitations.

im using this code right now

foreach (string drive in Directory.GetLogicalDrives())
{
TreeNode tn = new TreeNode();
tn.Text = drive;
tn.Value = drive;
TreeView1.Nodes.Add(tn);
}

thanks in advance...
please i m really stuck at this.

Best Regards,
Punit Belani

You have to use any Scripting language to do so. Use Javascript to get the files on the client system and then bind it to tree or any control you want to show the result.

Use javascript to achieve what you want.

Refer to this link for the code sample. It uses ActiveX to retrieve a list of drives in the client machine. However, this only works on IE as Mozilla doesn't support ActiveX by default. You need to install an addin for that.

Hi,
I have two sites and I want to login from one to another. I have simply used Response.Redirect("http://www.site1.com?username=abc&password=123").
I have encrypted username and password for security.
I want only to confirm is this approach good or not?

Thanks

No, not at all!

Username/password or any sensitive information should never be passed in querystring even if encrypted!

Set an authentication cookie. There's more than a few examples out there but here's a starting point for what I think you want:

Never ever use querystrings for this sort of thing. You're exposing an entry point, encrypted or no, for someone savvy enough to mess with.

yes, @Sandeep Mewara is true. there are many ways for decrypt your encryption. never use sensitive data in querystring.

Word press is written in PHP, I don't think you'll be able to easily integrate it into your asp.net app. There are plenty of other blogs you could use that are implemented in asp.net.

Just search it in CP Q&A forum. This has been asked number of times:

one of the ways: Try...In you logout event:

protected void LogOut()   
{       
     Session.Abandon();       
     string nextpage = "Logoutt.aspx";       
     Response.Write("<script language=javascript>");             
     Response.Write("{");       
     Response.Write(" var Backlen=history.length;");       
     Response.Write(" history.go(-Backlen);");       
     Response.Write(" window.location.href='" + nextpage + "'; ");
     Response.Write("}");       
     Response.Write("</script>");   
}

This particular question has been asked so many times. I am not able to provide you the codeproject search link for search "disable back".
You may try searching. You would get a lot of hits.
You may also search Google for "disable back button" if that does not satisfies you.
Here are few links from codeproject:

http://www.codeproject.com/Questions/73968/Disable-back-option-after-logout.aspx[^]
http://www.codeproject.com/Questions/53733/how-to-disable-browser-back-button.aspx[^]

Hope this helps!

The best option is
(1) check for a valid session object as the first statement to be executed for your page load event handler. If there is no session (or session object is null you write code to redirect user to login and force user to create a session. Assumption is, while logging out code is written to clear Session which has been created at the time of "Login".
(2) Sometime, developer creates "Base" page class and write this kind of session checking in base page itself so that every derived page class follows the same.

This way, you can set aside any dependency of javascript.

Hope it helps you,

Thanks,
