Hi,
yes, you might not have access to all existing folders (e.g. Vista prevents accessing the "System Volume Information" folder) so you need a try-catch inside the foreach that deals with accessing the individual folders. There are other things that might go wrong too, such as the local or networked drive disappearing, the folder disappearing, etc. so you need the try-catch anyway; without it the enumeration would suddenly come to a halt.

they exist, so they get reported by GetDirectories/GetFiles.
The method is not called GetAllFilesIWillBeAllowedAccessTo() you know.

Hello guys i would like to incorporate windows live maps with my application, the only problem is that my application is a windows application. Is it possabile to use windows live maps with a windows application? any ideas?
|

|
|
you can use a web browser control
|

|
|
|
ok thank you. Im gonna ask you another stupid question but worth a try.
For example I view some portion of the map and then the internet cuts, is it possabile to cache the view part of the map so that it can be viewable withour internet connection. Because in my project the application's scenario is based on a thrid world country.

Hello!
I have some code that add's users to my local administrator group.
But what i would like to accoplish is to add a user from an active directory to my localmachine admin group.
My code can add a local user to the local admin group.
I tried to alter the LDAP string for the ActiveDirectory connection but now it fails to add the domain user to the localmachine admin group.
The AD LDAP String: ldap://SERVERNAME01:389/CN=TESTUSER01,CN=Users,DC=DOMAIN01,DC=local
The Test String: WinNT://WORKGROUP/STEPHAN-F894E19/TestUser1
The Test String works the AD LDAP String doesn't work.
Can anyone help me with this?
Thanks!
the Code:
private void AddUserToGroup()
{
try
{
DirectoryEntry AD = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");
DirectoryEntry grp;
grp = AD.Children.Find("Administrators", "group");
if (grp != null) { grp.Invoke("Add", new object[] { "WinNT://WORKGROUP/STEPHAN-F894E19/TestUser1" }); }
MessageBox.Show("Account Created Successfully");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
|

i Found this code on CodeProject:
public void AddToGroup(string userDn, string groupDn)
{
try
{
DirectoryEntry dirEntry = new DirectoryEntry("LDAP://" + groupDn);
dirEntry.Properties["member"].Add(userDn);
dirEntry.CommitChanges();
dirEntry.Close();
}
catch (System.DirectoryServices.DirectoryServicesCOMException E)
{
}
}
But can anyone show me a sample LDAP String , UserDn String and a GroupDn String?
Thanks!

LDAP string - LDAP://CN=Administrator,CN=Users,DC=aDomain,DC=com
userDN - CN=aUser,CN=Users,DC=aDomain,DC=com
DN means distinguishedName
cool?

I haven't actually downloaded the software, just know of its abilities.
Microsoft has a tutorial on Platform Invoke at Platform Invoke Tutorial (C#)[^]
If you think that the official Microsoft tutorials don't tutor well (and I'd mostly agree with you), then Jason Clark wrote a pretty good piece for MSDN called Calling Win32 DLLs in C# with P/Invoke[^].
Either way that you learn, you'll need the signature of the method; you can get that from the VB script file.

Hi Curtis,
this has been a great help, and even though i understand it all much better. i still can't find the Entrypoints for the Dll. i have tried using Link /dump /exports dllname.dll and this doesn't return anything that is used in the VB script.
i have used COM browser and this shows more details, but when i use these details in the C# code it return a unable to find an entry point exception.
sorry to be a pain, could you help further?
Many Thanks,
Phil

Hi,
wouldn't IPAddress.Parse() take care of it?

Why do you ask these kind of questions to us?
The internet is like a very big book. To find some stuff in the book you can either ask people who have read it or you scan the text. For the big book called 'the internet' there are many full automatic scanners available (google.com for instance). If you have found a piece of usefull information, you should read the piece... if you'd done that, you wouldn't be asking questions.
