Is the memo field storing plain text? html-formatted text? rtf-formatted text?

Hi Mike,

I'm using richtext. I'm sure there's a way since I've done this in Delphi. I'm new to C# and just can't seem to figure it out.

Thanks,

WMI, How to browse schema of current class types?

Hi NG,

how can i browse the WMI Class schema on my local maschine. I would like to fill a tree view with WMI class types registered on my local machine.

i used the following code to get the namespaces:

ManagementClass nsClass = new ManagementClass(
                parentNode.ManagementScope,
                new ManagementPath("__namespace"),
                null );
            foreach(ManagementObject ns in nsClass.GetInstances()){}

the fetched namespaces are ok, but if i try to fetch the class types with

ManagementObjectSearcher searcher = new ManagementObjectSearcher(
					parentNode.ManagementObject.Scope,
					new WqlObjectQuery("select * from meta_class"),
					null);               
				foreach (ManagementClass wmiClass in searcher.Get()){}

there are only __XXXX class types, the Win32_LogicalDisk for instance is missing. Seems like i read the wrong data Frown | :(

Any Idea what it needs to show the display names for each class like Win32_LogicalDisk etc.?

Jerry,
If I understand your question correctly, the code below will grab the class names for a given namespace. Note the use of the "deep" option to force a traversal of all the classes in the namespace, not just the top-level ones. Hope this helps.
Jerry

ManagementPath nsPath = new ManagementPath();
nsPath.NamespacePath = <whatever namespace="" you="" want="">;

ManagementClass nsMgmtClass = new ManagementClass(nsPath);
System.Management.EnumerationOptions enumOpts = new EnumerationOptions();
enumOpts.EnumerateDeep = true;

string clsName = "";

foreach (ManagementObject obj in nsMgmtClass.GetSubclasses(enumOpts)) {
clsName = obj.ToString();
CbxClassName.Items.Add(clsName);
}

Hi NG,

i try to load and save some configuration data at startup/shutdown in my vs.net 2003 addin.

But i can't create a IsolatedStorageFileStream. The exception message is

{"Unable to determine identity of assembly." }

If i run the UserControl which is nested in a ToolWindow standalone everything works fine.

Any Idea?

I am building a multi-threaded application with numerous amount of threads ---- The thing is for each thread it has to be a random name and I do not know howto to create and start random named threads ----

help is greatly appreciated Thanks

Threads = headache
Random threads = insane!

Theortically you could create a hashmap or similar, create a random string value for the key and an instance of the thread for the value.

That way you would have random names associated with the threads, plus you could still enumerate through the collection. Plus the collection could grow and shrink as necessary.

But please... dont Wink | ;-)

print in landscape

Can one change printer orientation to landscape, using c# and no API?
I can't even get hands to default printer.

To print in C# you'll want to investigate the PrintDocument class - probably create a sub-class of it or at least set a print handler. PrintDocument has a PrinterSettings property for setting the printer, and a DefaultPageSettings property which can be used to set landscape orientation.

Here are a couple of articles on the topic:

You are not quite provide sufficient information for an answer.
For example, if you are using a Windows Form application, then are you using the PrintDialog control?? That gives you access to the printers and allows the user to define printing landscape.

i am using Windows Forms application.
But i am printing a Crystal report from Crystal Viewer using its default toolbar button.
I set landscape orientation in Printing Options for the report. So, it is PRESENTED in landscape. But, when it is printed, its printed in default printer orientation.
So I need a way to change default orientation, print report, then change it back.
Unsure | :~

Sounds like "left hand to right ear", but can't see any other way.

Datagrid in Winform

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?

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!
