Hello friends of the Forum
I go to their valuable help with the following problem

It is possible from net to automate Directory Activates.
Concretely I want to activate the directive one that this in

Configuration of User
Administrative insoles
System
And to enable the directive one
Alone to Execute applications of allowed windows
And to establish the list of programs EXE that the user can execute, I can them
to select of a list.
Example: winword.exe, excel.exe, etc.

My idea is that the user can make it from ASP.net

I wait their valuable help, and thank you for their time

try this to get you started, it shows how you can use System.DirectoryServices to query Active Directory.

Another solution would be to see how you can utilise WMI to interogate your active directory.

connection.open()

I didn't get any requirements for the signature

SqlConnection Example from MSDN[^]

private static void OpenSqlConnection()<br />
{<br />
    string connectionString = GetConnectionString();<br />
    using (SqlConnection connection = new SqlConnection(connectionString))<br />
    {<br />
        connection.Open();<br />
        Console.WriteLine("ServerVersion: {0}", connection.ServerVersion);<br />
        Console.WriteLine("State: {0}", connection.State);<br />
    }<br />
}<br />
<br />
static private string GetConnectionString()<br />
{<br />
    // To avoid storing the connection string in your code, <br />
    // you can retrieve it from a configuration file, using the <br />
    // System.Configuration.ConfigurationSettings.AppSettings property <br />
    return "Data Source=(local);Initial Catalog=AdventureWorks;"<br />
        + "Integrated Security=SSPI;";<br />

Question int or Int32

When I am using a varible inside a method (let's say 25 lines of code)

Should I create an int variable or Int32? What the heck is the difference?

I didn't get any requirements for the signature

Judah Gabriel Himango14-Aug-07 7:15

There is no difference. int is a C# keyword that's simply an alias for System.Int32.

Oh, that clears it up then. I suppose string and String are the same as well?

The Framework classes have names starting with an uppercase letter,
such as System.String

C# has type specifying keywords in lowercase, each of them corresponds
to one of the System.Xxxx types. Yes string corresponds to System.String

this weeks tips:
- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information
- before you ask a question here, search CodeProject, then Google

Here's a hint: if you're in Visual Studio, hover your mouse over string, or double, or int, and it should pop-up a little info showing the aliased type.

Not quite. Please read the documentation on this more carefully. I believe int in a 32-bit system is 32 bits as suggested, but in a 64 bit system, int becomes 64 bits.

As a result of that information, when it is known that 32 bits will suffice, please be sure to use Int32. Otherwise, when your program is run on a 64 bit system you could have unexpected results.

Yeah. nice.. Thanks...

That is completely false, don't listen to him. Jeez, the misinformation is astounding.

In .NET, a C# int just aliases System.Int32, which is 32 bits no matter what operating system you're on, including 64-bit OSes.

oh.. Thanks... Judah. it's the best if it's like that.. We, .NET dev, won't need to care about what OS the users are running.. good. Smile | :)

That's completely false. In .NET a C# int simply aliases System.Int32, which is *always* 32 bits, regardless of whether you're running on a 64-bit OS.

Now, in native C++, int may be different widths on different operating systems. But if you're coding in .NET, an Int32 is always 32 bits.

I need proof (besides the MSDN documentation) that int is always 32 bits. Will MS change their minds about the size of int in the future? Who can tell. For those reasons it is always best to ensure that you know the size of the variables that are in use.
