Im just starting to play with manipulating Active Directory using C# (never done any C# before).
I've followed some examples and extracted data for a given user, but its returning some odd data as follows:

badPasswordTime = System.__ComObject
lastLogoff = System.__ComObject
lastLogon = System.__ComObject
pwdLastSet = System.__ComObject

What is "System.__ComObject" and why am I not getting numeric data back?
Am I doing something wrong or missing something?

The code I am using (just a sample pulled off the web) is as follows:

<code> static void Main(string[] args)
{
string path = "LDAP://domain.com";
DirectoryEntry entry = new DirectoryEntry(path,"USERNAME","PASSWORD");

try{
Object native = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=ADTEST)";

foreach(SearchResult result in search.FindAll())
{
DirectoryEntry dirEntry = result.GetDirectoryEntry();
foreach (string key in dirEntry.Properties.PropertyNames)
{
foreach (Object propValue in dirEntry.Properties[key])
{
Console.WriteLine(key + " = " + propValue);
}
}
}
}
catch( Exception ex )
{ throw new Exception(ex.Message); }
Console.ReadKey();
}
}
}</code>

Any suggestions welcomed.......Thanks!

i think there should not be any problem in this case. Simply get the selected values from list and pass them to get values from database for datagrid.

Hi everybody.
I have a project which is developed by visual c#.net by visual studio 2005.
It is a database project and because of damaging the connection in anywhere of my application, I put the main method in try catch block which handles SqlException.
When I run the application, the try catch code works. But when I execute my application exe, the try catch code does not work. And unhandled exception message is shown and says to handle SqlException exception. I really get confused what to do...
My code in visual studio running mode, works but when executing the exe file, it does not work. I think it is the worst error for programmers.
Please help me with my stupid problem.

Thanks
Rastgar

Thanx in advance

queer error message

Hi!
From time to time visual studio 2005 shows a queer error message:

'Code generation for property 'Cursor' failed. Error was: ''CursorConverter' is unable to convert 'System.Windows.Forms.Cursor' to 'System.ComponentModel.Design.Serialization.InstanceDescriptor'.'

Maybe it happens because i use an own UserControl. But in fact this UserControl doesn't make anything with the property cursor ... WTF | :WTF:

Is there anybody who knows this error message and can say what's wrong!?!?

Thanks in advance!

As far as I can tell, this seems to be a bug in Visual Studio (still present in VS 2008).
A workaround that worked for me was to mark the property with an attribute to make it invisible
to the designer, as follows:

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] // Bug in VS requires this workaround
public Cursor MyCursor{ get; set; }

Cool! A response after more than three years Big Grin | :-D

I thought I am the only one who has this problem, so I've learned to live with this Bug. But now I will try this workaround.

Many thanks!

Fill dataset

Got my CustomRowEvent working..
able to fill my textboxes in my new form.

but i think it's not the fastest or best way.

i now use this line of code :

t075_BORGTOCHTNUMMER_1TextBox.Text = Grid["t075BORGTOCHTNUMMER1DataGridViewTextBoxColumn", RowIndex].Value.ToString();<br />

this work just great.. really..
BUT...
if you got about.. 60 textboxes.. it's kinna like a lot of work..
so i was thinking..
if i change my fill command with something like this..:

<br />
this.dBANBM_T075_BORGTOCHTTableAdapter.Fill(testdb1DataSet, Grid, RowIndex);<br />

he give's me the error that Grid and RowIndex does not excist in my current contex..

however..
i use the following code

<br />
        public dborgtocht(testdb1DataSet DSet, DataGridView Grid, int RowIndex)<br />
        {<br />
            InitializeComponent();<br />
            PopulateTextBoxes(testdb1DataSet, Grid, RowIndex);<br />
}<br />

so you really should think that he should be able to find them..

hope i explained enough now.

int [] abc = new int[20]; where 20 is array length

or

int [] xyz = {1, 2, 123, 54, 67, 324}; //here you have defined constant array

in first case u can set array value by
abc[0] = 1;
abc[1] = 2;
abc[2] = 123;

I am doing a network application that involves DataTables transfer over the network, is there some way to convert the DataTable to an array of bytes to be transfered or even a way to transfer the whole DataTable through the socket layer without worrying about the underlying procedures.
Thanks in advance.

Can u pls tell me, wether following SQL string format is correct or not.
textWord.text,comboCat.text are string variables of C#.
indexInCategoryTable and SubCategoryNo are integer variables.

"select * from Words where
word = N'"+textWord.Text+"' and

CategoryTableName = '"+comboCat.Text+"' and

IndexInCategoryTable = 'indexInCategoryTable' and

SubCategoryNo = 'SubCategoryNo'";

No it is not, because your string values you are concatenating into the sql string but your integer values are not.

Reflection and Overloaded Methods Problem !

User 20930738-May-06 21:18

User 2093073

8-May-06 21:18

Dear Friands,
I have two overloaded methods with the following signatures in 'MyClass' that is a class library in a dll file and I want to invoke a method from this dll at runtime by reflection:

public class MyClass()
{
  public int MyMethod(ref int intParam)
   {
     intParam += 100;
     return Math.Sin(intParam);
   }

  public int MyMethod(int intParam)
   {
     intParam += 100;
     return Math.Sin(intParam);
   }
}

When I use typeof(MyClass).GetMethod("MyMethod"); ,System.Reflection.AmbiguousMatchException is throw !!

If I use
typeof(MyClass).GetMethod("MyMethod",new Type [] {typeof(int)});
The second overloaded method with the value parameter invokes.
How can I force the CLR to run the first method and pass the parameter to it by reference ?

Regards,
Xironix

If you call DoEvents in your code, your application can handle the other events.

Say, you are are updating the label text by 10% within a function. You wont be able to see updated label text messages until the function has completed its execution. If you use Application.DoEvents() just after the update ui code, the function will continue its execution and you UI will be updated

label1.Text="20% completed";
Application.Doevents();

Have a look into this link
