Is there a way to find the difference between the two. I see in ADSI EDIT there is a group type, but is that it?
Here is my code which gets ALL the groups.. Which by the way, this works TONS faster than using the AccountManagement from 3.5 way.
Here is the code to get the groups from a single user:
RegistryAccess reg = new RegistryAccess();
PrincipalContext adPrincipalContext;
if (reg.LDAPauth) adPrincipalContext = new PrincipalContext(ContextType.Domain, reg.LDAPpath, reg.LDAPusername, reg.LDAPpassword);
else adPrincipalContext = new PrincipalContext(ContextType.Domain, reg.LDAPpath);
UserPrincipal user = UserPrincipal.FindByIdentity(adPrincipalContext, this.UserName);
PrincipalSearchResult<Principal> results = user.GetAuthorizationGroups();
foreach (Principal result in results)
{
AddListBoxCurrent(result.Name);
}
Now that only returns like 5 for a single user, but using this to get ALL of the groups is faster.. i mean it finishes populating the entire AD groups before populating the listbox with the groups for jsut that user:
try
{
using (DirectoryEntry root = new DirectoryEntry())
{
RegistryAccess reg = new RegistryAccess();
root.Path = "LDAP://" + reg.LDAPpath;
if (reg.LDAPauth)
{
root.Username = reg.LDAPusername;
root.Password = reg.LDAPpassword;
}
using (DirectorySearcher searcher = new DirectorySearcher())
{
searcher.SearchRoot = root;
searcher.SearchScope = SearchScope.Subtree;
searcher.Filter = "(ObjectCategory=group)";
searcher.PropertiesToLoad.Add("name");
searcher.PropertiesToLoad.Add("grouptype");
SearchResultCollection results = searcher.FindAll();
if (results != null)
{
int count = results.Count;
foreach (SearchResult result in results)
{
ResultPropertyCollection props = result.Properties;
foreach (string propName in result.Properties.PropertyNames)
{
if (propName == "name") AddListBoxAvail(props[propName][0].ToString());
}
}
}
searcher.Dispose();
root.Close();
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
So my first question is, how do I just get security groups, then just get distribution groups. What I am trying to do is populate a listbox on the left that "The user belongs to" and populate a listbox on the right that has "available security groups". So you can click a button to add or remove groups to that user. But how do I just get "Security groups" for this part, then I'll have another part for Distribution groups?

hi,
i have a program that receiving inforamtion from a port (SerialPort object).
i am reading the port's information(Stream) from another object by StreamReader like this:
SerialPort port=new SerialPort(.....);
port.NewLine= "\r";
StreamReader sr=new StreamReader(port.BaseStream);
while reading the the stream to the end:
while (!sr.endOfFile)
{
line= sr.readLine();
}
this Method stucks on the last line on the stream.it reads all the Stream except the last line.
But after adding information (Strings) to the stream (from the port).. it continues reading the last line with the new information...
do you know how to solve it?
thank you..
P.S
Maybe..is it something with the sr.NewLine argument?
|
|
|
|
|
Try sr.ReadLine != null in while loop condition.

it stucks on readLine. i mean, the processor arrives to this line (line= sr.readline()) and just stop.
even if i add another line to while:
while(!sr.endOffile)
{
line= sr.readline(); <------------it stops here------
messageBox.show("Just string"); the processor do not arrive to this line
}
the processor stops working even if the Stream is not endOfFile. Why?!
P.S
i changed !sr.endofFile to line!=null it is still not working...

ReadLine doesn't terminate until it encounters a NewLine; try a different method.

You want to hide and show the textboxes? Do you think it is possible to show and hide something at same time?
pramod2517 wrote: pls send me code.
No.

1. Rephrase your question. Clearer this time.
2. Try something yourself.
3. Use google.

Do you mean that if the form is shown via the Submit Button then the TextBoxes should be hidden, otherwise they should be shown?
If so, add a method to Form2, maybe
public void HideTextBoxes()
{
textBox1.Visible = false;
}and call that method after instanciation but before Show() in your submit button's handler.

Use delegates to create communication between forms, then an event in one form, can cause a method to be called in another.

Multiply ways to do this...
-in form2 declare a variable and decide on it's value
set it's value through constructor
-declare properties and user them

Hey,
I have a device for which I have to install the drivers. For this, I have the required .sys files as also the .inf file.
I wish to have the drivers installed before I plug in my device so that the "Found New Hardware" wizard can be avoided i.e. the device when plugged in for the very first time is recognised by windows and drivers are found installed.
Can anybody please guide me as I have not worked on device drivers earlier ?
Thanking you in anticipation.....
Regards,

If the instructions for the device do not tell you how to do this, I would suggest that you are likely to encounter problems.
Why not just follow the instructions?

i am having a text file of 10*10 integer datas...i am reading and writing into another textfile using readline method...but in this program i did some mistake...i couldn't get the output file with datas...here is the program
private void button1_Click(object sender, EventArgs e)
{
try
{
string path = "c:\\Vicky\\DATAS\\matrix.txt";
string path2 = "c:\\Vicky\\DATAS\\copy.txt";
FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
StreamReader sr = new StreamReader(fs);
FileStream fs1 = new FileStream(path2, FileMode.Create, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs1);
string line;
while ((line = sr.ReadLine()) != null)
{
sw.WriteLine(line);
}
fs.Close();
sr.Close();
fs1.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

That looks like File.Copy("c:\\Vicky\\DATAS\\matrix.txt", "c:\\Vicky\\DATAS\\copy.txt");
Anyway, you're closing the first stream twice. Remove sr.Close();
|
|
|
|
|
|
what is the format of the file?
|
|
|
|
|
.txt format..with full of image intensity values from 0 to 16000

|

Ok, that's not helping though, what is the actual format?
Something like:
(({decimal string}; )+{newline})*
what does it look like
Seriously, this could be important..

You need to close your StreamWriter:
fs.Close();
sr.Close();
fs1.Close();
to:
fs.Close();
sr.Close();
sw.Close();
fs1.Close();

thanks man....i got it....

Try this.
private void button1_Click(object sender, EventArgs e)
{
try
{
string path = "c:\\Vicky\\DATAS\\matrix.txt";
string path2 = "c:\\Vicky\\DATAS\\copy.txt";
using (StreamReader sr = new StreamReader(path))
using (StreamWriter sw = new StreamWriter(path2))
{
string line;
while ((line = sr.ReadLine()) != null)
{
sw.WriteLine(line);
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
You don't need to close the files/streams because using will do it for you.
Even if there is an exception.
I suggest setting a breakpoint on the while and stepping through the loop a few times.

Hi,
I can't see any obvious mistake in the code, so you should look for clues.
1) Does the input file contain the expected data
2) Do you get an output file. If yes is it empty
3) Does the output file timestamp get updated
4) Trace the code using the debugger and determine if the string variable 'line' contains the expected data from the input file.
Once you have done all of that come back to us and tell us what you have found.
Alan.

A general method for file copying, based on what you have, would look something like this:
bool FileCopy(string path1, string path2)
{
try
{
using (FileStream readFileStream = new FileStream(path1, FileMode.Open, FileAccess.Read))
{
using (StreamReader streamReader = new StreamReader(readFileStream))
{
using (FileStream writeFileStream = new FileStream(path2, FileMode.Create, FileAccess.Write))
{
using (StreamWriter streamWriter = new StreamWriter(writeFileStream))
{
string line;
while ((line = streamReader.ReadLine()) != null)
{
streamWriter.WriteLine(line);
}
}
}
}
}
return true;
}
catch
{
return false;
}
}
