If you dont know the names of drives you can get the names of drives using System.Management namespace with wmi.
After that i assume you have sharings on folders. then all you have to do is using a code like below

System.IO.Directory.GetFiles(@"\\10.10.0.50\d$");

Also you can use getdirectories or similar methods like this.

I think first you have to make an impersonation to a user that have rights on remote server.

Yo can find it here how to make.
Windows Impersonation using C#[^]

HI thanks for the reply,

Firstly i need to access the remote system based on IP address and then need to traverse the drives.

As u suggested,i used getfiles() and able to access,but the problem is, as the system is password protected, am unable to connect programatically.

so is there any way to pass the User id and password and access the remote system Harddisk drives

thanks in advance

For getting drive informations of a remote computer with wmi Windows Management Instrumentation (WMI) Implementation[^] will help.

For password protection of files issue only solution that comes to my mind is impersonation(Working the application under credentials of an user that has access to that files.

that because you dont specify return field name for time in
try change your query in "to_char('timein',...) as timein"

hope it helps

So, there is no column called 'timein'. I suspect you need to read a few basic books before doing any more work, the error message is pretty self documenting, and googling it would have got you a ton of info

In your select statement set "to_char(timein,'HH:MI')" to "to_char(timein,'HH:MI') AS 'timein'"
same with "to_char(timeout,'HH:MI')"

In addition to your missing columns, your code is vulnerable to SQL injection. You might want to look into stored procedures
