Shall i need to use RDC or any other option? thanks in advance Bobby Have a Nice Day Dudes Re: Accesing remote files Tamer Oz27-Jul-09 20:49 Tamer Oz 27-Jul-09 20:49  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.

Yo can find it here how to make. Windows Impersonation using C#[^] Re: Accesing remote files Kushi Bobby27-Jul-09 21:44 Kushi Bobby 27-Jul-09 21:44  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 Have a Nice Day Dudes Re: Accesing remote files Tamer Oz28-Jul-09 1:01 Tamer Oz 28-Jul-09 1:01  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. Re: Accesing remote files Kushi Bobby28-Jul-09 15:25 Kushi Bobby 28-Jul-09 15:25  HI Tamer, Thanks for the reply.

Christian Graus27-Jul-09 21:01 Christian Graus 27-Jul-09 21:01  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 Christian Graus Driven to the arms of OSX by Vista.

My form has a many images. If I run the project, images on the form are appearing one by one and form is vibrating. So plz give me any solution for this. Thanks in advance.. Re: Images on the winform Christian Graus27-Jul-09 19:59 Christian Graus 27-Jul-09 19:59  I'm not sure what you'd like to hear. I mean, what do you expect us to do here ? You have not told us how you show the images. You have not even told us if you want to show lots of images at once, or one at a time. I have no idea what 'form is vibrating' means. At the end of the day, if you can't provide some details, and some code for us to try to correct for you, I don't see how you expect to get any help Christian Graus Driven to the arms of OSX by Vista.
