I have a datagrid showing 200+ records, if user scrolls down to select a row that is off the initail screen, can I set the datagrid to show that part of data around the selected row to avoid user using scroll bar again and again.

Thanks,

If I understood well, you want to be able to scroll the DataGrid to a certain position.
DataGrid has some protected members that you can use to handle scrolling: VertScrollBar, HorizScrollBar, GridVScrolled, GridHScrolled.

For vertical scrolling I recommend you to do something like this:

public class MyDataGrid:DataGrid
{
public void ScrollToPos(int position)
{
ScrollEventArgs sea= new crollEventArgs(ScrollEventType.ThumbPosition,position);
this.GridVScrolled(this,sea);
}
}

Best Regards,

Try something like the following:

string domain = ...;
string newComputer = ...;
string groupName = ...;

// Connect to AD and get the computer container object
DirectoryEntry deDomain = new DirectoryEntry("WinNT://" + domain);
DirectoryEntry deNewComputer = new DirectoryEntry("WinNT://" + domain + "/" + newComputer + ", computer");

// Connect to the group container and add the computer object
DirectoryEntry deGrp = deDomain.Children.Find(groupName, "Group");
if (deGrp.Name != null)
    deGrp.Invoke("Add", new Object[]{deNewComputer.Path.ToString()}); 
deGrp.CommitChanges();

I'm starting an application with windows Forms. I know how change the current Culture and since this action every resouces that open, take the new Culture Value( System.Threading.CurrentThread.CurrentUICulture = new Globalization.CultureInfo (String * IdCulture) (...) )

OK that's right, but what happens with the Main Form that is Loaded since the start of execution?
Can I do a Reload or something like that, by anyway, or assing dinamically another ResX File to the MainForm for translate it without Close()?

Advanced thanks, gurus. I expect your answers Big Grin | :-D

Instead of putting this code in the constructor or something else that initializes controls (default for forms designers), put it in a separate method that re-instantiates the ResourceManager and assigns the localized strings / objects to the respective control properties.

You can also create a ResourceManager for a specific culture rather than setting the current thread's UI culture, but this usually a good idea to do anyway.

Using Explorer control to display HTML code?

I have some code

How can I use Explorer control to display it? And how can I add some images in this control in run-time? D'Oh! | :doh:

Thank u very much Rose | [Rose]

1) Create a new C# Windows application
2) Go in the Toolbox, right-click, add a new item. Choose the "COM components" tab, and select the "Microsoft web browser" (shdocvw.dll)
3) drop the web browser onto the form
4) select the web browser control
5) show the Properties window, click on the laser icon to show all events
6) in front of NavigateComplete, add an event handler, for instance : OnNavigateComplete.
7) go back in the solution tree, right-click and add a reference, browse then choose "Microsoft HTML document" (mshtml.dll)
8) open the C# code
9) add the #using mshtml; statement at the top
10) in InitializeComponent(), add the following code :

// fake IE startup
object o = null;
Show();
axWebBrowser1.Navigate("about:blank", ref o, ref o, ref o, ref o);

Then, implement your event handler like this :

private void OnNavigateComplete(object sender, AxSHDocVw.DWebBrowserEvents2_NavigateComplete2Event e)
{
  IHTMLDocument2 doc = (IHTMLDocument2) this.axWebBrowser1.Document;
  doc.body.innerHTML = @"<img src='http://www.arstdesign.com/iconpdf.gif' border=0>";
}

As you can see, the event handler is only here to temporize before the Internet Explorer instance is up and ready. Once it is, we add the html code to render with a simple doc.body.innerHTML statement.

Good luck!

Adding to the registry directly: http://msdn.microsoft.com/library/en-us/shellcc/platform/shell/programmersguide/shell_basics/shell_basics_extending/fileassociations/fileassoc.asp[^]

From an installer project in VS.NET: http://msdn.microsoft.com/library/en-us/vsinstal/html/vehowaddingremovingfiletypes.asp[^]

Don't forget to search MSDN or your documentation in VS.NET. Good research skills are important.

Any good Active Directory programming books?

I'm looking for book recomendations for developing against Active Directory with C#.

I've gone through the DirectoryServices namespace documentation in the MSDN library, but it falls short in covering the directory entry properties, etc... or I just haven't been looking in the right place.

Any good books or web references would be appreciated.

Thanks,

Hi, I have been trying to look in the msdn library, but found nothing, maybe because i dont know what i am looking for. If you know how to obtain a list of computers in a domain, it would be helpful if you told me, or told me where to look.

Thanks

In most cases, you can P/Invoke NetServerEnum in the Network Management API. There's no native way in .NET. You could possibly, however, use classes in the System.Management namespace to query WMI if you have an AD WMI provider. I can't remember off the top of my head if one comes with NT by default or now, or if it even exists. That's really about the only way without P/Invoking anything.

You can also use a slew of AD functions, but that will include P/Invoke functions and redefining structs and constants when needed.

First thing: pick up a book on programming in C#/.NET. You'll definitely need it because this isn't a drag-n-drop solution and real skill is needed.

Second thing: C# (Csharp as you called it) only targets the .NET Framework. If you don't understand this, you're bound for trouble. You should not only read a good book on this but look over the first few topics in the .NET Framework SDK documentation to understand what .NET is.

Programming isn't something you can just jump into with any decency. If you want to learn, start basic. Creating an email application - especially one that uses specifications like POP3 - isn't an easy task. Start simple like just creating a simple Windows Forms application with a toolbar and some controls and make it do something.

CodeProject here offers a lot of articles for newbies and experienced developers alike. These forums are great for asking questions if you don't understand something in the documentation, but you should at least check the documentation first. Being able to research a problem is very important in any field - especially in programming. It's also a good idea to look over the .NET Base Class Library (BCL) to see what's available because there's a lot of things that can help, although nothing will solve your immediately problem directly.

AFAIK, you should be able to use the same standard date format as in SQL Server. What about this?

strcmd = "select * from table_1 where datentime = '2003-11-12 17:45:34'";

Thank you.
